| titletext = They always try to explain that they're called 'solar physicists', but the reporters interrupt with &amp;quot;NEVER MIND THAT, TELL US WHAT'S WRONG WITH THE SUN!&amp;quot;&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&amp;quot;Breaking news&amp;quot; is a phrase which describes news reports which are considered important enough to interrupt (or &amp;quot;break&amp;quot;) scheduled broadcasts. The phrase is also often used to describe scheduled reports on important current events. When a new development in an active story occurs, news channels will often interview an expert in the field to educate laymen in what, exactly, is happening. Thus, when you turn on the local news and see a scientist being interviewed, it is likely that something new has come up regarding their field of study that could affect you.&lt;br /&gt;
&lt;br /&gt;
How much it affects you could range from an interesting bit of information about your local area, to the complete annihilation of the human race. So, to help identify how serious the issue likely is, [[Randall]] has made this chart showing how worried you should be depending on the field of the scientist. A [[#The fields of science|table]] has been arranged to explain the amount of worry needed for each field below.&lt;br /&gt;
&lt;br /&gt;
To the far left, the least worrying are {{w|archaeologist}} and {{w|economist}}. An archaeologist studies ancient human civilizations, which would be unlikely to harm any modern person. Economists study and explain the trends of finances and resources, which are also unlikely to pose an immediate threat.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
Following this, it shows {{w|Nutrition|nutritionists}} and eventually {{w|criminologists}}. A nutritionist studies nutrition in the human body, and is likely discussing which food options are healthy or unhealthy. While this may be important, it is not a cause for immediate concern. A criminologist, however, studies criminal behavior. If a criminologist is being interviewed on the news, there is likely a change in criminal actions within the neighborhood, be it more or less. It is also possible there may be a serial criminal working in the area. However, because crime is a relatively rare occurrence, and one for which precautions can be taken, it is still unlikely to be an immediate threat to the viewer.&lt;br /&gt;
&lt;br /&gt;
It then moves past researchers studying different types of organisms, before reaching astronomers. Still only very few events would be local regarding astronomy, but it could of course be regarding a pending meteor strike.&lt;br /&gt;
&lt;br /&gt;
A {{w|virologist}} studies {{w|Virus|viral}} infections and their spread, and a {{w|vulcanologist}} studies {{w|volcanoes}}. Viruses spread quickly, and can be fatal, meaning a breaking news development in one's locale regarding viruses is likely to mean imminent danger. Volcanoes, depending on their size, can potentially demolish entire countries, thus having one making headlines nearby is also very concerning.&lt;br /&gt;
&lt;br /&gt;
The last point to the right (most worried) &amp;quot;Astronomer who studies the Sun&amp;quot;, also called a &amp;quot;{{w|solar physicist}}&amp;quot; (mentioned in the title text), could be really troublesome, but not especially locally. If there are serious problems with the Sun it will be a world-wide problem. But you should still be worried. &lt;br /&gt;
&lt;br /&gt;
The title text mentions that the reason they are not called solar physicists, is that before they can tell the reporter this, they are interrupted by the anxious reporter who wishes to know what's wrong with the Sun. This is not really something that happens so often{{Citation needed}} that the title texts &amp;quot;They always try&amp;quot; has any real meaning. And this is also why no one knows or uses the term solar physicists...&lt;br /&gt;
&lt;br /&gt;
==The fields of science==&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
! Field !! Worry level !! Explanation&lt;br /&gt;
|-&lt;br /&gt;
| Archeologist || Extremely low (~2.7%) || Likely just dug up some old ruins or bones. Unlikely to involve bad news, though it may possibly cause problems (e.g. if a construction project is delayed to accommodate an archaeological investigation).&lt;br /&gt;
|-&lt;br /&gt;
| Economist || Very low (~7.3%) || News about the economy could be either good or bad, and in most cases is just more of the usual ups and downs rather than anything cataclysmic. Could also be a report on a big stock market crash.&lt;br /&gt;
|-&lt;br /&gt;
| Nutritionist || Very low (~12.0%) || Possible fad diet. Note that nutritionists tend not to be a protected profession, compared to dietitians. May be alarming if it involves credible information about bad health consequences of eating, or not eating, a particular food.&lt;br /&gt;
|-&lt;br /&gt;
| Criminologist || Low (~26.6%) || Probably just crime statistics. Sometimes just correcting people who mistakenly believe crime is on the rise, and even a large increase in an otherwise ordinary crime rate is still a small risk overall. Specific threats (such as a dangerous criminal on the loose) are usually addressed by police representatives.&lt;br /&gt;
|-&lt;br /&gt;
| Ornithologist || Medium (~43.3%) || This would indicate the discovery of a strange behavior exhibited by birds. A newsworthy event involving ornithologists could indicate some imminent problem with the ecological environment, such as a mass migration or death event suggesting toxic pollutants in the environment. A possible reference to ''{{w|The_Birds_(film)|The Birds}}'' or ''{{w|Birdemic}}'', two films with similar premises (horror films centered around flocks of birds suddenly becoming hostile to humans) but vastly different critical evaluations (''The Birds'' was directed by {{w|Alfred Hitchcock}} and is generally considered a classic; ''Birdemic'' was low-budget and is notoriously poor-quality).&lt;br /&gt;
|-&lt;br /&gt;
| Botanist || Medium (~46.0%) || Similar to an ornithological related news. Seeing how plants are both more fundamental to the environment and more &amp;quot;boring&amp;quot; to the general public than birds; if something news worthy involves a botanist, then it is more likely a more fundamental and more impactful change to the environment.&lt;br /&gt;
|-&lt;br /&gt;
| Marine Biologist || Medium (~53.3%) || Similar to Botanist news. However, as oceans represent the substantial majority of the Earth's surface, and are very far removed from local concerns, anything which is news-worthy of them is likely a major impact to the environment on a global scale. Additionally this may be a referential nod to the ''{{w|Godzilla}}'' franchise, as a marine biologist would be a likely interview candidate if a hitherto unknown amphibious monster were observed to come out of the ocean on a destructive visit to coastal cities.&lt;br /&gt;
|-&lt;br /&gt;
| Entomologist || Medium high (~62.6%) || There might be a new invasive insect species that could cause health concerns, ranging from {{w|Locust|famine}} to {{w|Mosquito|blood-transmitted diseases}}.&lt;br /&gt;
|-&lt;br /&gt;
| Astronomer || High (~82.0%) || Possible inbound meteor, or perhaps sighting of incoming alien ships.&lt;br /&gt;
|-&lt;br /&gt;
| Virologist || Very high (~88.0%) || A disease that is incurable and spreads fast might ravage or even destroy a city, country, or (in an extreme case) all human life. Slightly over two years after this comic's release, an example of a worrisome virus appeared in the form of {{w|COVID-19}},{{Citation needed}} which resulted in many interviews with epidemiologists. &lt;br /&gt;
|-&lt;br /&gt;
| Vulcanologist || Very high (~93.3%) || A volcano might erupt soon, the danger of which could range from an isolated area to a planetwide concern.&lt;br /&gt;
|-&lt;br /&gt;
| Astronomer who studies the Sun || Extremely high (~98.6%) || There might be something wrong with the Sun, the consequences of which could range from {{w|Solar_storm_of_1859|major disruption of modern technology}} to the end of life on earth. The title text elaborates that, [[1475: Technically|technically]], the correct term is &amp;quot;{{w|Solar physics|solar physicist}}&amp;quot;. Unsurprisingly, reporters (and the general audience) aren't particularly interested in such a pedantic matter, and want to be informed about the more pressing issue regarding the fiery ball that maintains the Earth's orbit and capacity for life.{{Citation needed}}&lt;br /&gt;

&lt;div&gt;I'm just a school teacher of Geography and English who isn't at all good at maths or anything IT-related and rather enjoys practical analogue activities, many of them outdoors, as well as playing lead guitar in an old-school rock band. So I might not look like a (stereo)typical ''xkcd'' fan at first glance, but I love it even so. Big fan of ''What If'', too, especially as in my position as a Geography teacher I often get asked similar questions that I'm more or less expected to answer on the spot, and Randall's great work actually helped me quite a bit then and again. Also, on second thought, I do dabble a bit in amateur stargazing and other such stuff amateurs are not meant to do, so there's that.&lt;br /&gt;
&lt;br /&gt;
Btw. I loathe and despise everything connected with generative AI. The way it has been introduced to the public and is currently used I see a very black dystopian future ahead, where creativity, art, music, independent original thought in general is stifled because it lures too many stupid people into thinking all of these were obsolete as activities to bother pursuing yourself. It's the one invention from the past one hundred years that makes me deeply concerned. Ok, so there's nuclear weapons, but the two pretty much share the lead on humanity's all-time worst inventions list. My favourite dream is of a huge solar storm that deletes all this AI stuff along with the 90% of the internet that (in compliance with Sturgeon's Law) are crud. Since it'd delete the whole internet, I hope and pray us webcomic creators will manage to make analogue backup prints in time so we can re-upload it all afterwards. Webcomics make up a vast bulk of the good 10% if you ask me.&lt;br /&gt;
&lt;br /&gt;
Btw.Btw. I've been a webcomic creator myself for many years, even though it all is currently on a prolonged hiatus. Unlike many creators who say this, I'm really going to bring it back one day.&lt;br /&gt;

&lt;br /&gt;
Anyways, all of the above is why I don't identify as a nerd. I've got nothing against nerds, and I don't even think of it as an offensive term, but rather as one of respectful endearment. I just know I'm not one of them, OK? There's certain skill sets I'll never get up to a high enough level, either. However, I do value intellectual curiosity and an open mind above everything else, and I love an occasional challenge even outside of my comfort zone, and whenever I can make a productive contribution here, I'll be happy to.

Where's Greenland? [[User:SubtrEM|SubtrEM]] ([[User talk:SubtrEM|talk]]) 20:00, 30 July 2025 (UTC)&lt;br /&gt;
:It is on the backside of North America globe of course. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:49, 31 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
My first edit! Hope it's ok! [[User:Jkusa.jr| Jkusa.jr]] 08:12, 30 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Wait, maybe I'm crazy, but I feel like there's actually a good map idea here? If you made proper globes centered on each continent.... Does this exist? [[Special:Contributions/2601:241:8002:3E0:CE5:D9D:CF64:76FD|2601:241:8002:3E0:CE5:D9D:CF64:76FD]] 21:36, 30 July 2025 (UTC)&lt;br /&gt;
:Well... that is what a globe is. You just turn it until it is on the continent you wish and look from the right angel ;-) Drawing a globe on a paper does nothing to remove the distortion from normal flat maps. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:49, 31 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Not sure what the joke is!  Another dis of the concept of continents?   [[Special:Contributions/2A09:BAC3:9C1B:1955:0:0:286:B1|2A09:BAC3:9C1B:1955:0:0:286:B1]] 22:01, 30 July 2025 (UTC)&lt;br /&gt;
:It is a bad map projection. That is a joke in it self. Another way to badly draw a map, that is the ongoing joke. Of course there is also the silly joke in the title text like the Earth is actually spread over 7 spheres. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:50, 31 July 2025 (UTC)&lt;br /&gt;
:The thing is, attempts to translate a full sphere to a flat map requires various compromises (e.g. points that are close in real life may appear far apart on the map). Translating subsets of a full sphere out onto their own complete spheres technically requires the ''opposite'' type of compromises (e.g. points that are far apart in real life are now very close...). And add to that inevitable choice of angular and area distortions. [[Special:Contributions/82.132.244.235|82.132.244.235]] 10:12, 31 July 2025 (UTC)&lt;br /&gt;
:It sometimes ''does'' feel as if a lot of people around the world were living on different planets, so we might as well go all out with the concept. Makes sense to me. [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 11:59, 31 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Yet another map that ignores/erases New Zeeland. {{unsigned|ProfKrueger|01:28, 31 July 2025}}&lt;br /&gt;
:No it doesn't ignore it. Just like Greenland is on the other side of the globe in North America so is NZ on the other side of Australias globe. You cannot either see Sydney or Tasmania or LA or other Western states in the US. In Europe you cannot see most of Scandinavia (although the important part is there ... Denmark ;-) and Madagascar is also left our near Africa as is the entire middle east and most of Russia. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 07:49, 31 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
Thought Randall was becoming political leaving out N.Korea, Middle east, and Russia; then noticed the colossal China...--[[User:Darth Vader|Darth Vader]] ([[User talk:Darth Vader|talk]]) 09:42, 31 July 2025 (UTC)&lt;/div&gt;</summary>

&lt;div&gt;Discovered this explanation fresh off the griddle. The transcript doesn't even exist yet wow. Also, hi! This is my first time commenting! Did I do it right? [[User:Giraffequeries|Giraffequeries]] ([[User talk:Giraffequeries|talk]]) 22:54, 25 July 2025 (UTC)&lt;br /&gt;
:(Yes, looks like you did.)&lt;br /&gt;
:A couple of hours on, and nobody's attempted the Transcript yet. If you're still around right now-ish and you've got more time than everyone elses seems to have (including me, sorry), that could be your next thing.&lt;br /&gt;
:Check prior Transcripts for the right kind of way (and a few wrongs, but hey?), and imagine the words+'markup' being read through the hypothetical screen-readers. That might not know how to 'audible' a table, may at best shout/stress '''bold-strong'''/''italics-emphasis'', but perhaps not correctly.&lt;br /&gt;
:But just getting the words down helps the next soul with a few more minutes at hand. Any normal weekend, I'd be happy to do it right now, but I've got to be up in five hours, and I mildly regret just checking right now to see if I might have missed the latest comic popping up when it was a bit earlier and I was prepping my weekend bags. :) [[Special:Contributions/82.132.236.123|82.132.236.123]] 01:49, 26 July 2025 (UTC)&lt;br /&gt;

Given that this wiki doesn't really like tables, and this one is formatted rather simply, maybe we should just transfer its content to the transcript and retain only explanations in the main part, as separate paragraphs?

Just a small explanation to the Quarternary/Tertiary naming issue because this has become rather obscure and is seldomly spelled out in newer geology textbooks: When the first geologists came up with a table of geologic epochs it consisted of four parts: &amp;quot;Primary&amp;quot;, &amp;quot;Secondary&amp;quot;, &amp;quot;Tertiary&amp;quot; and &amp;quot;Quarternary&amp;quot;. Only the last two names have survived into our time, because the first two parts became split up into the systems that we still use today rather quickly. This is also the main reason that most stratigraphers want to get rid of the terms Tertiary and Quarternary and why Paleogene/Neogene were invented instead. [[Special:Contributions/2003:DD:472A:5500:35F8:1CD8:D274:E286|2003:DD:472A:5500:35F8:1CD8:D274:E286]] 14:46, 26 July 2025 (UTC)&lt;br /&gt;

The Quaternary is obviously so called because it's the period of Quatermass. [[Special:Contributions/82.13.184.33|82.13.184.33]] 09:46, 28 July 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
If y'all disagree with my docutainment interpretation, feel free to erase it again of course, but the common denominator in Randall's table here really ''is'' each period's entertainment value as a focal point. Also, I'd like to add that it's not a bad thing at all for a documentary to be entertaining; quite the opposite. For example, I might never have studied geography if it wasn't for films about interesting foreign places and cool-looking books about volcanoes and dinosaurs and weather, all of which I devoured in my childhood.

*Need more explanation for the entries with birds and raptors: give an explanation similar to the other time periods, and add why he both links and and hates raptors. These are the main jokes in the comic, yet they are not explained at all. Also, were there birds so early?}}&lt;br /&gt;
&lt;br /&gt;
This comic depicts a table representing planet Earth's geological time scale. The table lists the 12 geological periods of the {{w|Phanerozoic}} Eon and the {{w|Precambrian}} Eon. The names are listed in chronological order. The first six formal Periods (Cambrian through Permian) belong to the {{w|Palaeozoic}} Era, the next three to the {{w|Mesozoic}} Era, and the final three to the {{w|Cenozoic}} Era. For each period, [[Randall]] has chosen to highlight his rather idiosyncratic likes and dislikes among their characteristics, instead of accompanying each geological name with facts pertinent to it, such as the duration of the period represented, the state of the Earth (e.g. glaciated) during the period, or the flora and fauna most commonly associated with the period. That way the whole setup and style is strongly reminiscent of a typical TV show synopsis in tabular form as could be found at various places on the internet, including [https://en.wikipedia.org/wiki/Xena:_Warrior_Princess_season_2 Wikipedia]. This may refer to the way heavily CGI-assisted reconstructions of life in past geological periods are a popular topic for documentary and so-called docutainment shows, which often focus more on entertainment value than the science behind it (hence the term ''docutainment'').&lt;br /&gt;

|The {{w|Precambrian}} (italicized in the comic since it's not a {{w|Period (geology)|geologic period}}) is the first 88% of Earth's history, including the time 4.1 to 3.4 billion years ago when life on Earth began. It's an informal 'catchall' term encompassing the {{w|Hadean}}, {{w|Archaean}}, and {{w|Proterozoic}} Eons that preceded the Phanerozoic. The {{w|Snowball Earth}} hypothesis says that during some time spans in the past, Earth became nearly or entirely frozen, with no liquid water on the surface. It's related to the idea of the {{w|Greenhouse and icehouse Earth#Icehouse Earth|icehouse Earth}}, times when the planet fluctuates between glacial and interglacial periods (such as now).&lt;br /&gt;

|A series of mountain-building events during the middle to late Devonian, collectively termed the {{w|Acadian orogeny}}, resulted in a section of the present-day Appalachian Range from the Canadian maritimes to the Carolinas, including what is now the Boston area of Massachusetts. (At the time, Boston was in the tropics, just south of the equator.) {{w|Placoderm}} fishes, which were common in but did not survive the Devonian, were characterized by plates of {{w|dermal bone}} in the head and thoracic portions of the body. Not all placoderms were giants, or apex predators.

The title text expands on the &amp;quot;third&amp;quot; &amp;lt;em&amp;gt;v&amp;lt;/em&amp;gt; &amp;quot;fourth&amp;quot; Quaternary Period complaint by postulating the existence of an unnamed geologic period within the Cenozoic Era &amp;quot;that geologists won't tell us about&amp;quot;. In fact, the use of &amp;quot;Quaternary&amp;quot; (and &amp;quot;Tertiary&amp;quot;) in recent/current geological nomenclature is a relic of four centuries of the history of geological studies in Western Europe, complicated by the religiously-inspired acceptance until the beginning of the 19th century, among European scholars, of an Earth that was only 6000 years old. See {{w|Geologic time scale#Formulation of a modern geologic time scale|this summary}} for more details, but briefly, &amp;quot;Primary&amp;quot; rocks were those considered to have been present, in solid formations such as mountains, before the &amp;quot;Great Deluge&amp;quot; of Noah (the {{w|Genesis flood narrative}}), while &amp;quot;Secondary&amp;quot; rocks represented the rubble from the Flood. Igneous and metamorphic rocks came to be understood as &amp;quot;primary&amp;quot;, and eldest (within the context of a 6000-year-old Earth), and sedimentary rocks as &amp;quot;secondary&amp;quot;. Demonstrably more recent geological formations came to be known as &amp;quot;tertiary&amp;quot; (relatively newer) and &amp;quot;quaternary&amp;quot; (even more recent). As the idea of Earth being billions of years old gained acceptance and tools for accurately dating rocks became available, &amp;quot;primary&amp;quot; and &amp;quot;secondary&amp;quot; fell away as descriptors for both rock types and rock ages, replaced by terms that convey information about the rocks more precisely and accurately. &amp;quot;Tertiary&amp;quot; was applied to &amp;quot;Cenozoic minus Quaternary&amp;quot;, and survived in formal nomenclature into the 21st century. No similar replacement for the term &amp;quot;Quaternary&amp;quot; has yet been accepted, and so the name persists as fodder for cartoonists who wonder, not without cause, how a &amp;quot;third&amp;quot; element in Earth history could be labeled a &amp;quot;fourth&amp;quot; element.&lt;br /&gt;

&lt;br /&gt;
This comic depicts a table representing planet Earth's geological time scale. The table lists the 12 geological periods of the {{w|Phanerozoic}} Eon and the {{w|Precambrian}} Eon. The names are listed in chronological order. The first six formal Periods (Cambrian through Permian) belong to the {{w|Palaeozoic}} Era, the next three to the {{w|Mesozoic}} Era, and the final three to the {{w|Cenozoic}} Era. For each period, [[Randall]] has chosen to highlight his rather idiosyncratic likes and dislikes among their characteristics, instead of accompanying each geological name with facts pertinent to it, such as the duration of the period represented, the state of the Earth (e.g. glaciated) during the period, or the flora and fauna most commonly associated with the period. That way the whole setup and style is strongly reminiscent of a typical TV show synopsis in tabular form as could be found at various places on the internet, including [https://en.wikipedia.org/wiki/Xena:_Warrior_Princess_season_2 Wikipedia].&lt;br /&gt;

|The {{w|Precambrian}} (italicized in the comic since it's not a {{w|Period (geology)|geologic period}}) is the first 88% of Earth's history, including the time 4.1 to 3.4 billion years ago when life on Earth began. It's an informal 'catchall' term encompassing the {{w|Hadean}}, {{w|Archaean}}, and {{w|Proterozoic}} Eons that preceded the Phanerozoic. The {{w|Snowball Earth}} hypothesis says that during some time spans in the past, Earth became nearly or entirely frozen, with no liquid water on the surface. It's related to the idea of the {{w|Greenhouse and icehouse Earth#Icehouse Earth|icehouse Earth}}, times when the planet fluctuates between glacial and interglacial periods (such as now).&lt;br /&gt;

|Due to the non-random location of impact of one type of meteorite, {{w|Rings of Earth|it is proposed}} that those may have formed a planetary ring system around Earth before colliding with it. The volcanic eruption(s) that deposited the {{w|Deicke and Millbrig bentonite layers}} of ash during the Late Ordovician are thought to have been among the largest in the last 600 million years of Earth history.

Igneous and metamorphic rocks came to be understood as &amp;quot;primary&amp;quot;, and eldest (within the context of a 6000-year-old Earth), and sedimentary rocks as &amp;quot;secondary&amp;quot;. Demonstrably more recent geological formations came to be known as &amp;quot;tertiary&amp;quot; (relatively newer) and &amp;quot;quaternary&amp;quot; (even more recent). As the idea of Earth being billions of years old gained acceptance and tools for accurately dating rocks became available, &amp;quot;primary&amp;quot; and &amp;quot;secondary&amp;quot; fell away as descriptors for both rock types and rock ages, replaced by terms that convey information about the rocks more precisely and accurately. &amp;quot;Tertiary&amp;quot; was applied to &amp;quot;Cenozoic minus Quaternary&amp;quot;, and survived in formal nomenclature into the 21st century. No similar replacement for the term &amp;quot;Quaternary&amp;quot; has yet been accepted, and so the name persists as fodder for cartoonists who wonder, not without cause, how a &amp;quot;third&amp;quot; element in Earth history could be labeled a &amp;quot;fourth&amp;quot; element.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by A HOT-TEMPERED NEIGHBOUR. Don't remove this notice too soon.}}&lt;br /&gt;
&lt;br /&gt;
Using electricity to heat the home used to involve direct use of {{w|Joule heating|resistive heating}}, but has more recently been replaced by developments in heat-pump technology which, much like the operation of a typical refrigerator, uses a small amount of power to move heat to where it is most needed (away from where the heat is ''not'' required). This is most commonly done using an {{w|air source heat pump}} which can extract heat from the ambient outside air and use that to heat the inside of a household, and its hot-water supply. Because of the varying nature of the external climate, this is less efficient (or at least more technically difficult) in colder weather, the time when the heating would be most appreciated.&lt;br /&gt;
&lt;br /&gt;
An alternate method of harvesting heat is the {{w|ground source heat pump}}. This does the same job of extracting heat energy from ''its'' surroundings (pipes sent deep into the ground, rather than just being exposed to the air by the side of the building), and benefits from the more constant temperature of the pedosphere (or deeper), giving a ''relatively'' warm heat-source, to extract energy from, even in the depths of winter. If set up to also cool the home, it also finds the same small range of ground-temperatures useful in being ''cooler'' than the ambient air of summer, thus being more suited to disperse excess heat into whilst cooling the indoors environment. A further method, the water source heat pump, similarly makes use of a sufficiently large body of water's tendency to provide a near constant 4°C temperature (whatever the external conditions) in its depths.&lt;br /&gt;
&lt;br /&gt;
In this comic, Randall goes further and finds a handy source of heat (in winter) and cold (in summer)… the house of a neighbour, which is itself being actively maintained (perhaps by more traditional heating and cooling technology) at a temperature which approaches his own preference for temperature. Being thermally inverted to the current seasonal conditions, it would be even more economical to tap into for heat during cold times and coolness during the warmer ones. At least it would be for Randall, not the neighbour who is now forced to effectively air-condition ''two'' buildings, instead of the one they thought they were maintaining.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The title text addresses some of the issues involved when trying to properly install the Neighbour-Source Heat Pump, without the neighbour realising that they are about to be leeched from in this way.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
While the small-scale application suggested here can thus be assumed to cause neighbourly trouble, this concept has been in use on much larger scales for about the last ten years &amp;lt;url=https://www.bbc.com/future/article/20200908-the-buildings-warmed-by-the-human-body&amp;gt;BBC, 9/9/2020&amp;lt;/url&amp;gt; with virtually no repercussions - which is largely due to the tapped neighbouring premises not being residential buildings.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|This page was created by a bot that should not have tried this. The explanation is still a DRAFT. Don't remove this notice too soon.}}&lt;br /&gt;
This is another one of [[Randall|Randall's]] [[:Category: Tips|Tips]], this time an Aerospace tip. &lt;br /&gt;
&lt;br /&gt;
{{w|Drafting (aerodynamics)|Drafting}} is an aerodynamic technique where one moving object follows another one closely to reduce drag by using the first objects {{w|slipstream}}. It is used in various sports, most prominently {{w|cycling}}.&lt;br /&gt;
&lt;br /&gt;
The comic explores the idea of using drafting for rockets and states that while it theoretically works, it isn't really recommended. &lt;br /&gt;
&lt;br /&gt;
The title text gives more details on this, claiming that although there is an efficiency gain of 5% through drafting via the general mechanism, it also comes with a 99% loss. Trying to closely follow a rocket, directly against the flow of its extremely hot and high-speed exhaust, could have adverse effects on the follower's flight. There might also be a risk to the leader, if the follower collides with it or if the follower explodes.&lt;br /&gt;
&lt;br /&gt;
Generally, this could be understood because land transportation is based on traction (pulling yourself along a surface via friction). At higher speeds (above 60km/h), the dominant force becomes wind drag. {{w|Energy-efficient driving}} at these higher speeds can be improved by drafting behind another vehicle. This doesn't apply to rockets because they do not move themselves via friction but rather via Newton's third law (throwing stuff backwards). This means that the front rocket would just push the back rocket against its own thrust (among other bad effects).&lt;br /&gt;
&lt;br /&gt;
It should be mentioned that drafting behind another land vehicle in regular traffic is a potentially lethal high-risk endeavour, as the truck in front of you may suddenly have to brake for one reason or another{{Citation needed}} and human reaction times are generally too long when you're close enough for this method to have any significant effect. Rockets do not suddenly brake in mid-flight{{Citation needed}}, so this may be said in their favour as leading vehicles - that is of course, if you feel that blowing up in a spectacular fireball is preferable to being violently crushed into a metal pancake.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A rocket with two boosters is launching going towards the top right corner. It has a two-stage core and two boosters, and they produce three flames from their exhaust and beneath these flames is a large exhaust plume fanning out behind the rocket most of the way towards the bottom of the panel. A smaller rocket is following the first rocket. It is very close to the first rocket, so most of the smaller rocket is inside the exhaust plume from the larger rocket. The smaller rocket does not have boosters, but still produces three smaller flames from its exhaust. Beneath these flames the smaller rocket also leaves a large but slimmer exhaust plume that exits the panel at the bottom left corner.]&lt;br /&gt;
&lt;br /&gt;

:Aerospace tip: Although the technique reduces atmospheric drag for many types of vehicles, you should '''''never''''' try to improve rocket launch efficiency through drafting.&lt;br /&gt;

&lt;br /&gt;
Using rice paper you could easily reach 9 steps by pure hand pressure, although reaching fusion point -at or around 80 steps- would definitely require strong fingers indeed. Black holes clearly cannot exist, because they would require folding Chinese paper more than a red-blooded American can do, and this is not an option.{{unsigned ip|141.101.68.192|22:13, 3 January 2025}}&lt;br /&gt;
&lt;br /&gt;
The current explanation that it's impossible to create a black hole by folding paper is only right in practical terms. If you manage to keep folding while keeping the same thickness the density of the paper will be far beyond that of a neutron star.--[[User:Pere prlpz|Pere prlpz]] ([[User talk:Pere prlpz|talk]]) 22:42, 3 January 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
I would be impressed if you did manage to keep folding, since the goal size can be measured in Planck lengths with only six digits. Would you define it as a 'fold' after the entire thing fits inside an electron? (Tangentially, I'm not sure what theory suggests here - can a black hole exist at a scale which makes quantum tunnelling trivial?) {{unsigned ip|172.68.210.114|23:09, 3 January 2025}}&lt;br /&gt;
:I don't think we'll be able to answer that until we unify QM and GR. I don't think we currently have a theory that addresses quantum-sized black holes. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 23:23, 3 January 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
This strip loosely follows a routine by Emo Philips in the 1980's where he describes tearing a piece of paper in half repeatedly until it explodes.  He didn't give a count though. [[Special:Contributions/172.71.154.140|172.71.154.140]] 01:22, 4 January 2025 (UTC)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
So, based on some quick math: &lt;br /&gt;
If we take the 10^110 meters of paper needed to complete this many folds, then you definitely can easily make a black hole. Generously assuming a 1mm wide strip, this gives us a folded stack of paper 1mm wide, 10^53 meters tall and long. 1 light year is 10^15 meters. So this piece of paper is now 10^38 light years long and wide. I.e. something like 10^27 universes tall and long.&lt;br /&gt;
&lt;br /&gt;
Using the 70g per square meter number used above, you get 7^105 kg total mass. One solar mass is roughly 2^30 kg. Our paper weighs something like 10^54 times as much as the observable universe. This is very likely enough to reverse the expansion of the universe, and cause the entire observable universe to turn into a black hole. Or would it be a new big bang? I wonder what theoretical physics would say about a universe with 10^54 times as much mass / energy.&lt;br /&gt;
&lt;br /&gt;
Also how exact does this comment system work? Is it easier if I just make an account? &lt;br /&gt;

I wonder what theoretical physics would say about a universe with 10^54 times as much mass / energy.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic references various questions submitted by people and used in the [[what if? (blog)|''what if?'' blog]] and the ''[[What If? (book)|What If?]]'' and ''[[What If? 2]]'' books. In particular, promoting [[Randall]]'s new book, ''What if? 2'' (released 6 days after the date of this comic publication). This comic has a list of things not to do, an extension of a previous list, and is purportedly things Randall discovered as he was doing research for his book.  A visit to the [https://what-if.xkcd.com/archive/ What If? archive] shows the titles, publishing date, and a thumbnail for each article.  Many of the acts described under the &amp;quot;new&amp;quot; section of the list are depicted in these thumbnails (see table below); others are references to examples or hypotheticals explored within the articles. The entries are all in order of their appearance in the book.  &lt;br /&gt;
&lt;br /&gt;
The title text says that Randall is tempted to tell people that all the things in the book were things that he actually tried to do, not that he calculated the solutions for their problems. Many of the questions and answers in his new book are impossible to attempt in real life.{{citation needed}}&lt;br /&gt;

|Eat Tide Pods&lt;br /&gt;
|N/A&lt;br /&gt;
|{{w|Consumption of Tide Pods|Tide Pod}}s are a brand of laundry detergent sold in small packets (&amp;quot;pods&amp;quot;) of water-soluble gel. Many children have tried to eat them, thinking them to be candy, and have had to go to the hospital to treat poisoning. In 2017 and 2018, a satirical &amp;quot;challenge&amp;quot; originated around eating Tide Pods.&lt;br /&gt;
|-&lt;br /&gt;
|156,813&lt;br /&gt;
|Walk on stilts in a thunderstorm&lt;br /&gt;
|N/A&lt;br /&gt;
|Taller objects are more likely to be struck by lightning, so walking on stilts outdoors would increase the risk of death by electrocution. It would also presumably risk falling and injuring oneself that way, since the ground becomes wet in a rainstorm.&lt;br /&gt;
|-&lt;br /&gt;
|156,814&lt;br /&gt;
|Set off fireworks at a gas station&lt;br /&gt;
|N/A&lt;br /&gt;
|This has the risk of potentially causing an explosion in the gas station, from the sparks of the fireworks.&lt;br /&gt;
|-&lt;br /&gt;
|156,815&lt;br /&gt;
|Feed your cat treats that are the exact shape and texture of a human hand&lt;br /&gt;
|N/A&lt;br /&gt;
|This probably runs the risk of the cat learning that treats are in the shape of your hand, resulting in the cat attempting to eat your hand, instead of the cat treat.&lt;br /&gt;

|Lean over a geyser vent and try to look down into it&lt;br /&gt;
|Geyser&lt;br /&gt;
|Geysers shoot steam and hot water upward. If a person were to lean over the geyser and look down during an eruption, they would be struck in the face by this hot liquid and gas mixture and severely injured or killed.{{Actual citation needed}} This is a reference to the question from ''What-If? 2'' (called, appropriately enough, &amp;quot;Geyser&amp;quot;), in which it is asked what might happen to a person if they stood on top of the Old Faithful geyser as it erupted.&lt;br /&gt;
|-&lt;br /&gt;
|156,817&lt;br /&gt;
|Fly a hot-air balloon over a firing range&lt;br /&gt;
|[https://what-if.xkcd.com/81/ Catch!]&lt;br /&gt;
|A hot air balloon could present an irresistible target to the people firing their weapons at the range. The balloon could be shot and you could fall to your death. Shooting bullets up and over the designated backstop and berm is also a public danger to anyone past downrange.&lt;br /&gt;

|Peel away the earth's crust&lt;br /&gt;
|Lose Weight the Slow and Incredibly Difficult Way&lt;br /&gt;
|This is a reference to an entry in the new book, and an image of what it would look like is shown in [[2575: What If? 2]], where a potato peeler is used to remove the crust of the Earth. Several *What If* blog posts also result in massive damage to the earth's crust, including what happened to Texas [https://what-if.xkcd.com/153/ here]. &lt;br /&gt;
&lt;br /&gt;
This is a reference to a chapter from the new book, which refers to removing the Earth's mass to lose weight.&lt;br /&gt;

|156,822&lt;br /&gt;
|Fill a lava lamp with actual lava&lt;br /&gt;
|[https://what-if.xkcd.com/122/ Lava Lamp]&lt;br /&gt;
|A {{w|lava lamp}} is a glass lamp, which contains a wax mixture inside, and heats so that the wax rises and falls. Putting actual lava inside a regular lava lamp would most likely cause the lamp to melt and the glass to shatter, not to mention handling lava is very dangerous, [https://youtu.be/h5Zwg3Ag-bE?t=632 all of which has been proven to be true.][https://youtu.be/h5Zwg3Ag-bE?t=704 (If you want to skip Mr Rober's ad, come back and click here.)] However, in this entry, Randall says it would be fairly easy to find a material that would be able to handle the heat of the lava and thus this would be rather anticlimactic.&lt;br /&gt;
|-&lt;br /&gt;
|156,823&lt;br /&gt;
|Drink the blood of someone with a viral hemorraghic (''sic'') fever&lt;br /&gt;
|[https://what-if.xkcd.com/98/ Blood Alcohol]&lt;br /&gt;
|Drinking someone else's blood is a bad idea unless you are a vampire. If someone has a {{w|viral hemorrhagic fever}}, it is much worse, as they have a very serious and likely deadly disease which can be transmitted by sharing bodily fluids, such as blood. Drinking blood is the theme of this answer. Randall teaches us that drinking blood would induce vomiting, and would be a VERY bad idea.&lt;br /&gt;
|-&lt;br /&gt;
|156,824&lt;br /&gt;
|Eat meat from rabid animals&lt;br /&gt;
|Short Answers #4&lt;br /&gt;
|Eating meat from rabid animals could give you {{w|rabies}}, a virus which is nearly always fatal if not treated prior to the appearance of initial symptoms. Pathogen contamination in cooked foods can persist on the surface of ''e.g.'' tongs, chopsticks, or a fork used to grill, which is why the USDA doesn't generally allow kitchen utensils to touch raw or ready to eat foods at all. Exceptions for utensils which touch only raw or partially cooked foods, such as grill spatulas and the like, are often allowed and can be negotiated on a case-by-case basis when they would otherwise be prohibited. The rabies virus permeates essentially all nerve tissue before symptoms appear.&lt;br /&gt;

|Perform your own laser eye surgery&lt;br /&gt;

|156,826&lt;br /&gt;
|Tell California poultry regulators that your farm is selling Pokemon eggs&lt;br /&gt;
|Read All the Laws&lt;br /&gt;
|While issuing false statements to government regulators is a violation of both California and Federal law, for which prison sentences can reach ten years and fines can reach ten thousand dollars plus any compensatory damages, as per [https://california.public.law/codes/ca_penal_code_section_132 California Penal Code § 132] and [https://www.law.cornell.edu/uscode/text/18/1001 18 U.S. Code § 1001], there is some question about whether any competent regulatory authority would ever take such an assertion seriously, and whether they would be liable for greater damages for doing so than the potential liability of the original culprit involved. Actually doing this, even to county level regulators, could result in a series of events very disadvantageous to you, your farm, and your employees. However, declaring that you're producing Pokémon eggs to your local municipality is probably harmless, and likely to brighten the day of your local regulators.{{cn}} Furthermore, as mentioned in ''What If? 2'', [https://california.public.law/codes/ca_food_and_agric_code_section_27637 California Food and Agricultural Code § 27637] bars anyone from making false or misleading statements about eggs, and Poké Balls could be considered a type of egg.&lt;br /&gt;

|Pump ammonia into your abdomen&lt;br /&gt;
|Ammonia Tube&lt;br /&gt;
|{{w|Ammonia}} is an [https://en.wikipedia.org/wiki/EPA_list_of_extremely_hazardous_substances extremely hazardous substance] and pumping it into your abdomen would result in a painful death due to ammonia toxicity. As the book mentions, however, at the very least some of it would be neutralized with your stomach acid.&lt;br /&gt;

|156,829&lt;br /&gt;
|Suspend yourself inside a 10-meter ball of sunscreen and fall into the Sun&lt;br /&gt;
|Sunscreen&lt;br /&gt;
|Despite its name, sunscreen only protects against some types of radiation from the sun. No amount is going to be adequate protection if you are right inside the sun.{{Actual citation needed}} Also, sunscreen, being a gel, would evaporate when exposed to vacuum. When exposed to the plasma of the coronal surface or the Sun's interior, it would quickly ionize along with anything inside it, becoming plasma like the rest of the Sun.&lt;br /&gt;

Putting actual lava inside a regular lava lamp would most likely cause the lamp to melt and the glass to shatter, not to mention handling lava is very dangerous, [https://youtu.be/h5Zwg3Ag-bE?t=632 all of which has been proven to be true.] However, in this entry, Randall says it would be fairly easy to find a material that would be able to handle the heat of the lava and thus this would be rather anticlimactic.&lt;br /&gt;

|Drink the blood of someone with a viral hemorraghic (''sic'') fever&lt;br /&gt;
|[https://what-if.xkcd.com/98/ Blood Alcohol]&lt;br /&gt;
|Drinking someone else's blood is a bad idea unless you are a vampire. If someone has a {{w|viral hemorrhagic fever}}, it is much worse, as they have a very serious and likely deadly disease which can be transmitted by sharing bodily fluids, such as blood. Drinking blood is the theme of this answer. Randall teaches us that drinking blood would induce vomiting, and would be a VERY bad idea.&lt;br /&gt;

|Eat meat from rabid animals&lt;br /&gt;
|Short Answers #4&lt;br /&gt;
|Eating meat from rabid animals could give you {{w|rabies}}, a virus which is nearly always fatal if not treated prior to the appearance of initial symptoms. Pathogen contamination in cooked foods can persist on the surface of ''e.g.'' tongs, chopsticks, or a fork used to grill, which is why the USDA doesn't generally allow kitchen utensils to touch raw or ready to eat foods at all. Exceptions for utensils which touch only raw or partially cooked foods, such as grill spatulas and the like, are often allowed and can be negotiated on a case-by-case basis when they would otherwise be prohibited. The rabies virus permeates essentially all nerve tissue before symptoms appear.&lt;br /&gt;

|Tell California poultry regulators that your farm is selling Pokemon eggs&lt;br /&gt;
|Read All the Laws&lt;br /&gt;
|While issuing false statements to government regulators is a violation of both California and Federal law, for which prison sentences can reach ten years and fines can reach ten thousand dollars plus any compensatory damages, as per [https://california.public.law/codes/ca_penal_code_section_132 California Penal Code § 132] and [https://www.law.cornell.edu/uscode/text/18/1001 18 U.S. Code § 1001], there is some question about whether any competent regulatory authority would ever take such an assertion seriously, and whether they would be liable for greater damages for doing so than the potential liability of the original culprit involved. Actually doing this, even to county level regulators, could result in a series of events very disadvantageous to you, your farm, and your employees. However, declaring that you're producing Pokémon eggs to your local municipality is probably harmless, and likely to brighten the day of your local regulators.{{cn}} Furthermore, as mentioned in ''What If? 2'', [https://california.public.law/codes/ca_food_and_agric_code_section_27637 California Food and Agricultural Code § 27637] bars anyone from making false or misleading statements about eggs, and Poké Balls could be considered a type of egg.&lt;br /&gt;

|{{w|Ammonia}} is an [https://en.wikipedia.org/wiki/EPA_list_of_extremely_hazardous_substances extremely hazardous substance] and pumping it into your abdomen would result in a painful death due to ammonia toxicity.

|Suspend yourself inside a 10-meter ball of sunscreen and fall into the Sun&lt;br /&gt;
|Sunscreen&lt;br /&gt;
|Despite its name, sunscreen only protects against some types of radiation from the sun. No amount is going to be adequate protection if you are right inside the sun.{{Actual citation needed}} Also, sunscreen, being a gel, would evaporate when exposed to vacuum. When exposed to the plasma of the coronal surface or the Sun's interior, it would quickly ionize along with anything inside it, becoming plasma like the rest of the Sun.&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|Created by a THE FIVE BEST EXPLAINXKCD USERS COMBINED INTO ONE - Table of each moons with its special ingredients as well as the volume and surface area, and compare the combined volume and combined surface area to that of Mars (also check both the actual surface area of the five as well as the surface area of a sphere with the total moons volume, which would be a much smaller surface area than of the five moons sum of surface area... Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic jokes that it is possible (and perhaps intended) to use the five largest moons in the outer solar system (the {{w|Galilean moons}} and {{w|Titan (moon)|Titan}}) as ingredients to create a “better” planet that has the “coolest features”. Apparently, though, Randall couldn't actually think of anything cool that {{w|Ganymede (moon)|Ganymede}} and {{w|Callisto (moon)|Callisto}} could contribute, so these have just been used as 'filler'. (Though Ganymede has a magnetic field, which is kind of cool...)&lt;br /&gt;
&lt;br /&gt;
Note that {{w|Moon|Earth's moon}} is the fifth-largest moon of the solar system overall ({{w|Europa (moon)|Europa}} is the sixth), so it would have been included had  &amp;quot;outer solar system&amp;quot; not been specified.&lt;br /&gt;

|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
If all of these moons were lumped together, the total volume of “Randall's planet” would be 2.48×10&amp;lt;sup&amp;gt;11&amp;lt;/sup&amp;gt; km&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;, assuming no further material compaction, with a surface area of 1.91×10&amp;lt;sup&amp;gt;8&amp;lt;/sup&amp;gt; km&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;. This is about 1½ times the volume of Mars, or roughly a 15% larger diameter. The combined mass, however, is smaller than that of Mars.&lt;br /&gt;
&lt;br /&gt;
The title text takes it further, treating asteroids as a “to-taste” ingredient in this “recipe”, treating it more like preparing a food dish rather than making a new {{w|Mars}}-sized planet.&lt;br /&gt;

It could possibly be related to the recently discovered asteroid [https://www.esa.int/ESA_Multimedia/Images/2024/06/Close_approach_of_asteroid_2024_MK 2024 MK] that made a close approach to Earth on June 29, 2024, but it could be any of the {{w|Jet Propulsion Laboratory}}'s Center for Near Earth Objects Studies' [https://cneos.jpl.nasa.gov/sentry/ Sentry objects]. &lt;br /&gt;
&lt;br /&gt;
Blondie mentions that according to the astronomers the asteroid only has a 'one-in-6000 chance of &amp;quot;doing something cool&amp;quot;,' meaning that there is only a small chance that the asteroid will have a direct impact on Earth's surroundings. What the astronomers deem as &amp;quot;something cool&amp;quot; would presumably be that the asteroid hits the Earth or the Moon. She then states that further observations have shown that this will not happen and the asteroid will just be yet another boring dot in the sky. &lt;br /&gt;
&lt;br /&gt;
The joke is that most people are afraid that an asteroid getting close to us would actually hit, and hope to hear that it will not. If this asteroid gets close enough that it will actually be a visible dot, then it is indeed very close to Earth given the normal sizes of {{w|Near-Earth object|near-Earth asteroids}}. Many people interested in the night sky would find it interesting to be able to see an asteroid with their naked eye.&lt;br /&gt;
&lt;br /&gt;
The title text may refer to another asteroid that gets even closer than the one depicted, because this one should come closer than the Moon according to calculations (presumably by the astronomers). However, this asteroid will not hit the Moon even though it gets this close, so the astronomers ask, what is the point? Again she says that the astronomers hope for some visible effect. The statement that it will not hit the Moon leaves it open if Earth will be hit or not.&lt;br /&gt;
&lt;br /&gt;
Unlike almost all of [[Randall]]'s other comics, this one involves {{w|boredom}} or ''ennui''. Because something interesting does not occur is often the most important experience in scientific inquiry, confirming the {{w|null hypothesis}}.

I assumed the lava lake would be used like a sand trap, so the golfer would want to hit the ball, rather than collect it. As such, the ball would likely be coated with a material of sufficiently high combustion temperature to be able to survive (at least for a while) on the surface of the lava. The golfer would then require shoes that allow for walking on the lake, but I believe such exist. &lt;br /&gt;
My question is, how difficult would it be to hit the golf ball off of the surface of the &amp;quot;lake&amp;quot;? There would be the added challenge of a &amp;quot;divot&amp;quot; composed of some of the lava following the ball, but at least you shouldn't need to worry about &amp;quot;repairing&amp;quot; the damage? [[User:Galeindfal|Galeindfal]] ([[User talk:Galeindfal|talk]]) 15:55, 3 September 2024 (UTC)&lt;br /&gt;
: My gut feeling (awaiting the results of further testing) is that lava adhered to your ball would impede your play. Unfortunately, current USGA rules would only allow you to clean away just enough to be able to identify your ball (e.g. if your ball was entirely encased in rock, you would be allowed to chip away at the rock until you can see the ball at which point you would have to stop chipping. This means that, tactically speaking, you would want to chip away at the outside, and at the areas where you don't think the ball actually is, first to attempt to remove as much rock as possible before the ball can be seen.) You would not be allowed a full cleaning until you reached the green. &lt;br /&gt;
: One slight advantage would be that an encased rock ball would result in a lot more embedded pitches (where a ball lands with enough force to create its own divot) which would permit you to move your ball a club-length away to escape the divot. It is probable that this advantage would not be enough to offset the disadvantage of having to hit a ball encased in lava rock. &lt;br /&gt;
: The introduction of lava hazards would likely require a new section in the rulebook to cover the above issues as well as the use of rock tumblers as enhanced cleaning machines, the introduction of new club types designed to survive the rigours of lava play, permissible footwear and enhanced caddy insurance policies.

This article contains a cool photo of golfers with a huge ash cloud erupting behind them: [https://www.golfpass.com/travel-advisor/articles/lava-golf-plenty-of-u-s-courses-live-in-the-shadows-of-nearby-volcanoes] It's probably a safe distance, really, but the photo makes it look as if it was right behind them.

: Two miles (3.2 klicks) from the golf course to Halemaumau, the main vent of the Kilauea summit caldera. (pats and caresses ground) Good volcano. Nice volcano. The eruption cloud shown resulted from the draining of the lava lake that had been in Halemaumau for a decade or so, before an earthquake opened a hole in the magma chamber. The lava flowed underground down the mountain and resurfaced in the Leilani Estates housing subdivision, destroying much of it. This was 2018 (as shown in the picture caption). We were living on the Big Island at the time (in Kailua Kona, safely on the other side of Mauna Loa from the eruption). Fun times! Sorta.

I do not think this current discussion is actually about XKCD at all, much less this comic. Perhaps the internet itself is that sixth lava lake, with all the hot mess it contains. [[Special:Contributions/172.68.22.253|172.68.22.253]] 02:54, 3 September 2024 (UTC)&lt;br /&gt;

In fact, the Volcano Golf Course [https://volcanogc.com] is built on an active volcano, Kilauea.&lt;br /&gt;
&lt;br /&gt;
: Also on Hawaii Island is the [https://www.fourseasons.com/hualalai/golf/ Hualalai Golf Course], which is one of several that have been built on the {{w|Hualalai}} volcano, which erupts less frequently than Kilauea, but is nonetheless considered active (the Kona airport is built on an 1801 lava flow).

:: Immediately I start wondering why there might not have been a perfectly workable airport ''beneath'' the 1801 lava flow.

Is the female character Megan, or [https://www.explainxkcd.com/wiki/index.php/Danish Danish]? Hair length and association with Black Hat suggest the latter. [[Special:Contributions/172.71.147.191|172.71.147.191]] 05:12, 3 September 2024 (UTC)&lt;br /&gt;

She would be traditionally be devious/sociopathic enough to have made the comment just now ''in order that'' Black Hat would do (something like) this.&lt;br /&gt;
:Image-wise, the figure sits somewhere between the 'reference images' of Megan's hair (right thickness, grown a bit longer here) and that of Danish (finer and more casually-longer), and there are a number of ambiguous appearances that are just a subtle change in hair away from either, so I couldn't say for sure without taking into account the dialogue/activities involved.

I assumed the lava lake would be used like a sand trap, so the golfer would want to hit the ball, rather than collect it. As such, the ball would likely be coated with a material of sufficiently high combustion temperature to be able to survive (at least for a while) on the surface of the lava. The golfer would then require shoes that allow for walking on the lake, but I believe such exist. &lt;br /&gt;
My question is, how difficult would it be to hit the golf ball off of the surface of the &amp;quot;lake&amp;quot;? There would be the added challenge of a &amp;quot;divot&amp;quot; composed of some of the lava following the ball, but at least you shouldn't need to worry about &amp;quot;repairing&amp;quot; the damage?

This one contains a cool photos of golfers with a huge ash cloud erupting behind them: [https://www.golfpass.com/travel-advisor/articles/lava-golf-plenty-of-u-s-courses-live-in-the-shadows-of-nearby-volcanoes] It's probably a safe distance, really, but the photo makes it look as if it was right behind them.

There is a nice site called [https://apod.nasa.gov/ Astronomy Picture of the Day] that is like this.  Alas, it is &amp;quot;A cool space thing happened three days ago - sorry you missed it&amp;quot;.  --[[User:Divad27182|Divad27182]] ([[User talk:Divad27182|talk]]) 11:41, 31 August 2024 (UTC)&lt;br /&gt;

Sounds like it needs a sky dome camera system (like they made for immersive filmimg) on the roof coupled with statistical analysis (mistakenly aka AI) to recognise and record 'interesting' things, coupled with localised alerts for known phenomena. A product for someone? [[User:RIIW - Ponder it|RIIW - Ponder it]] ([[User talk:RIIW - Ponder it|talk]]) 11:46, 31 August 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
Most cool astronomical events don't come up so suddenly that you need an alarm. We know about eclipses years in advance, meteor showers recur annually, comets have months of warning, and unusual auroras are usually known a few days early. Anything sudden will probably also be short-lived, so by the time you get outside it will be over. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:26, 31 August 2024 (UTC)&lt;br /&gt;
:If you're anything like me, you're often eager to see (predicable space phenomenon) and then get reminded of it a day too late when the photos starts appearing on the internet. Though that could just as easily solved with a reminder on a standard calendar app, if only you had something reminding youto set up reminders. What would be nice would be an app where you put in your location and it gives you the next week's A) weather forecast, and B) list of interestingly visible space thingies.

&lt;br /&gt;
Seems like there should be a name for these alerts, like &amp;quot;Amber Alert&amp;quot; for missing children. I nominate &amp;quot;Neil Alert&amp;quot; -- it should probably use Neil deGrasse Tyson's voice. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:28, 31 August 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
Since the characters in the comic are the same as in the previous ISS comic, I like to think that they're in the ISS and Megan is getting ready to do an EVA (ignore the fact that such a desk wouldn't make sense, or the walking, or that prepping for the EVA would probably take well over a full orbit) [[Special:Contributions/172.71.223.93|172.71.223.93]] 17:58, 31 August 2024 (UTC)&lt;br /&gt;

&lt;br /&gt;
Does anyone know of anything like this? Something that will tell me about things like upcoming meteor showers, comets, auroras, etc. the day before, rather than hearing about it the day after from people who somehow knew about it? To this day I still have no idea how people find out about these things before they happen {{unsigned ip|162.158.154.134|13:35, 1 September 2024}}&lt;br /&gt;
:Offline, the national (and local) Weather broadcasts might give info on &amp;quot;what might be visible tonight&amp;quot;. Or at least respond to the preceding News programme's &amp;quot;and finally...&amp;quot; if it features the note that supermoons will happen or aurora have a decent chance to and all that remains is the hope of clear sky. That's UK television, can't speak for wherever you are/what you might watch.&lt;br /&gt;
:Online, it would depend upon what you can imagine wanting to know. Keep an eye on something obvious like space.com (which might have internal/external links to gateways that push notifications on various subjects) or go the full hog and search for &amp;quot;aurora alert&amp;quot;, &amp;quot;meteor alert&amp;quot;, &amp;quot;rocket launch alert&amp;quot; in every sort of phrnomenon that you think might (if timed/located well) interest you and be visible.&lt;br /&gt;
:The comic device might be either configured to deal with everything the comic characters might be interested in, nails absolutely ''anything'' (without prejudice/selectability) or perhaps (over time) has an AI/heuristic element that 'learns' what random phenomena most interest you as it collates so many possible feed options (itself, or via its manufacturer's centrally maintained servers).&lt;br /&gt;
:But it looks like a project ripe for a 'Maker' to try. Set up an Arduino/Raspberry Pi/whatever with a &amp;quot;speaker/siren and lights&amp;quot; housing and an internet connection with suitably configured feed-scraping commands run within it (or via a separate computer to which it connects) that makes a fuss whenever a suitable notification is passed. Add to that maybe some skyward-facing camera(s) with one degree or other of image-processing applied to their images to (for example) identify when a particularly nice sunset is happening with plenty of rose-tinted clouds. With enough foresight (and the right processing) it could pick up particularly aesthetic cloudscapes, the spontaneous murmurations of starlings, an amusing conjunction of contrails, the first snowflakes of winter or (back to space things) a surprise Earth-skimming bolide... whatever your imagination, technical tinkering and subsequent data-munging could get your &amp;quot;Sky's-Pi Alarm&amp;quot; (or whatever it is) to make its noises for.&lt;br /&gt;
:I don't actually subscribe to anything (as proxy for my imagined self-contain/collating device), so I can't tell you any particularly good sources of info, but there'll be some out there. Like you can get earthquake alerts (or at least &amp;quot;yeah, we also know about it, be careful&amp;quot; semi-simultaneous detection), tornado alerts, flood aleets and other hobbyist/public-safety notification systems.

At the moment, a device like this might actually be useful for all of us who irritate their friends and family by going out every evening at around 10 when it's dark but Corona Borealis is still a fair distance above the horizon, because of this [https://www.skyatnightmagazine.com/space-science/t-coronae-borealis-nova nova-in-waiting]. There is a distinct chance it'll be cloudy on the nights it happens anyway, because ''that's reality: always pissing on the epic moment'' ([https://www.goodreads.com/book/show/89186.Pushing_Ice?from_search=true&amp;amp;from_srp=true&amp;amp;qid=cSxwg6qHB1&amp;amp;rank=6 this last part is a quote, here's the source]) As with many glorious celestial events, if you don't know what it signifies, it'll just be another of many inconspicious little dots of light, and if you don't know or care what the constellations normally look like, you won't even notice. It'll still be an awesome once-in-a-lifetime event to watch, but be aware at all times that for all practical purposes (and for so-called &amp;quot;normal&amp;quot; people) the awesomeness is all in your head.* [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 15:30, 1 September 2024 (UTC)&lt;br /&gt;
:* see [[1644: Stargazing]], [[2017: Stargazing 2]] and [[2274: Stargazing 3]] for further reference. To be honest, I'm actually waiting on xkcd's take on the event as much as on T Coronae Borealis going boom already.

I previously changed the words from the alarm in the Transcript to italics, but I wasn't convinced that the noises from the alarm were also italicized.  I see someone else changed them to italics as well, but I wonder if anyone else is of the same mind as myself. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 14:16, 1 September 2024 (UTC)&lt;br /&gt;
:The transcript shouldn't actually use (or rely upon) formatting, really, though saying something like &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;:[The device emits sounds and speech, in italics] ''The things the device says''&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt; in both description ''and'' markup would satisfy both human and non-human readers better than one method alone. I've not been involved in that transcript, probably won't, but it's the kind of expansion that I'd expect (done with more thought than this quick note, maybe).

To this day I still have no idea how people find out about these things before they happen {{unsigned ip|162.158.154.134|13:35, 1 September 2024}}&lt;br /&gt;
:Offline, the national (and local) Weather broadcasts might give info on &amp;quot;what might be visible tonight&amp;quot;. Or at least respond to the preceding News programme's &amp;quot;and finally...&amp;quot; if it features the note that supermoons will happen or aurora have a decent chance to and all that remains is the hope of clear sky. That's UK television, can't speak for wherever you are/what you might watch.&lt;br /&gt;
:Online, it would depend upon what you can imagine wanting to know. Keep an eye on something obvious like space.com (which might have internal/external links to gateways that push notifications on various subjects) or go the full hog and search for &amp;quot;aurora alert&amp;quot;, &amp;quot;meteor alert&amp;quot;, &amp;quot;rocket launch alert&amp;quot; in every sort of phrnomenon that you think might (if timed/located well) interest you and be visible.&lt;br /&gt;
:The comic device might be either configured to deal with everything the comic characters might be interested in, nails absolutely ''anything'' (without prejudice/selectability) or perhaps (over time) has an AI/heuristic element that 'learns' what random phenomena most interest you as it collates so many possible feed options (itself, or via its manufacturer's centrally maintained servers).&lt;br /&gt;
:But it looks like a project ripe for a 'Maker' to try. Set up an Arduino/Raspberry Pi/whatever with a &amp;quot;speaker/siren and lights&amp;quot; housing and an internet connection with suitably configured feed-scraping commands run within it (or via a separate computer to which it connects) that makes a fuss whenever a suitable notification is passed. Add to that maybe some skyward-facing camera(s) with one degree or other of image-processing applied to their images to (for example) identify when a particularly nice sunset is happening with plenty of rose-tinted clouds. With enough foresight (and the right processing) it could pick up particularly aesthetic cloudscapes, the spontaneous murmurations of starlings, an amusing conjunction of contrails, the first snowflakes of winter or (back to space things) a surprise Earth-skimming bolide... whatever your imagination, technical tinkering and subsequent data-munging could get your &amp;quot;Sky's-Pi Alarm&amp;quot; (or whatever it is) to make its noises for.&lt;br /&gt;
:I don't actually subscribe to anything (as proxy for my imagined self-contain/collating device), so I can't tell you any particularly good sources of info, but there'll be some out there. Like you can get earthquake alerts (or at least &amp;quot;yeah, we also know about it, be careful&amp;quot; semi-simultaneous detection), tornado alerts, flood aleets and other hobbyist/public-safety notification systems.

At the moment, a device like this might actually be useful for all of us who irritate their friends and family by going out every evening at around 10 when it's dark but Corona Borealis is still a fair distance above the horizon, because of this [https://www.skyatnightmagazine.com/space-science/t-coronae-borealis-nova nova-in-waiting]. There is a distinct chance it'll be cloudy on the nights it happens anyway, because ''that's reality: always pissing on the epic moment'' ([https://www.goodreads.com/book/show/89186.Pushing_Ice?from_search=true&amp;amp;from_srp=true&amp;amp;qid=cSxwg6qHB1&amp;amp;rank=6 this last part is a quote, here's the source]) As with many glorious celestial events, if you don't know what it signifies, it'll just be another of many inconspicious little dots of light, and if you don't know or care what the constellations normally look like, you won't even notice. It'll still be an awesome once-in-a-lifetime event to watch, but be aware at all times that for all practical purposes (and for so-called &amp;quot;normal&amp;quot; people) the awesomeness is all in your head.* [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 15:30, 1 September 2024 (UTC)&lt;br /&gt;
:* see [1644: Stargazing], [2017: Stargazing 2] and [2274: Stargazing 3] for further reference. To be honest, I'm actually waiting on xkcd's take on the event as much as on T Coronae Borealis going boom already.

I previously changed the words from the alarm in the Transcript to italics, but I wasn't convinced that the noises from the alarm were also italicized.  I see someone else changed them to italics as well, but I wonder if anyone else is of the same mind as myself. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 14:16, 1 September 2024 (UTC)&lt;br /&gt;
:The transcript shouldn't actually use (or rely upon) formatting, really, though saying something like &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;:[The device emits sounds and speech, in italics] ''The things the device says''&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt; in both description ''and'' markup would satisfy both human and non-human readers better than one method alone. I've not been involved in that transcript, probably won't, but it's the kind of expansion that I'd expect (done with more thought than this quick note, maybe).

:*It's all readable in the page history. Not worth reading, IMO, but it's there. But now not ''here''. Bye bye the whole (limited) discussion as a non-executive decision on my part. &lt;br /&gt;

The symmetry of the truss intrigues me. Struts that are diagonal across the faces of the cuboids is normal, but is it a real thing to also use the body diagonal? Never seen that IRL, not sure if it makes sense from the statics. --[[Special:Contributions/172.70.247.82|172.70.247.82]] 22:16, 19 August 2024 (UTC)&lt;br /&gt;
: Struts as shown provide some left-right stability, but not as effectively as struts across the face would.  They also provide some redundant front-back stability with the struts running along the faces. [[Special:Contributions/172.68.71.90|172.68.71.90]] 14:47, 21 August 2024 (UTC)&lt;br /&gt;
: I mentally modeled the flexibility modes, and it very much depends upon whether the verticals are solid (with their resistence to bending playing a big part alongside the incident horizontals'/diagonals' exactvmethod of attachment) or are just sections of rod between a suitable receiver-'node' at each junction.&lt;br /&gt;
: in particular, the strength of any one of the three 'boxes' (each level between adjacent horizontal cross-sectional perimeters) is somewhat less secure, as a single level can 'fold' sideways over each side's vertical-diagonal strut (along with the respective front/back horizontals, held 'square' by the internal cross-brscing). Only the continuation and linking with the other 'boxes' really guarantees any innate stability, and if each node is free-twisting then the likely first result of any failure is that the tower topples forwards and/or backwards as it folds up due to the unbraced facing and hindside quadrilaterals.&lt;br /&gt;
: But it does depend a lot upon the exact nature of the linkages (which can only be guessed at), and other failure-modes could involve node-slippage if they merely grip the cross-braces to the entirely top-to-bottom poles and there's potential for sliding there instead of primarily rotation (or over-stressed failure in any given length of rod).&lt;br /&gt;
: The support (or additional pressure) provided by the access staircase is also probably a factor. It could even be the most important bit in holding it up! ...if firmly anchored at the other end and robust enough in itself.&lt;br /&gt;
: I'd definitely add other diagonals (including opposite-type body-diagonals, perhaps tied to the existing one as they pass right across each other), just to be sure. The more the better, of course, but there's probably a limit through diminishing concerns. And too many diagonals primarily in a helical pattern could concentrate forces into a particular type of rotational failure if you also add too much brace-weight in doing so.

The explanation mentions there might be more complex calculus examples where the shape might not be a cylinder. I think some further explanation could be added that this does not change the pressure (hydrostatic paradox) but indeed change the rate of emptying the object. If differing cross sections are relevant at all. [[Special:Contributions/108.162.221.103|108.162.221.103]] 05:40, 20 August 2024 (UTC)&lt;br /&gt;
: Non-prismatic geometries are I think the ones being alluded to here, i.e a frustrum with the pointy end down will have a greater reduction in pressure for a given volume of flow towards the end than at the start, which may offset the reduction in absolute pressure. I've also seen examples where the flow rate is considered constant and the problem is to work out the fluid depth as a function of time, e.g. filling a pyramidal pool from a hose.

:: Yes... [[User:Transgalactic|Transgalactic]] ([[User talk:Transgalactic|talk]]) 10:10, 21 August 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is there anyone else who thought the calculus teacher was abusing the tank as a model for the complex plane, demonstrating how to [https://en.wikipedia.org/wiki/Removable_singularity remove a singularity] from a holomorphic function by puncturing the plane? I wasn't confronted with that particular tank-emptying problem in high school, so my first encounter with &amp;quot;holes&amp;quot; in maths was in complex analysis. The title text was a mystery. [[User:Transgalactic|Transgalactic]] ([[User talk:Transgalactic|talk]]) 10:10, 21 August 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
As a mathematician, I'm surprised I didn't know about this idea. (It's definitely not my field!) I actually thought the flow would be constant, an algebraic problem. Oh, I'm sure I saw these types of problems in Calculus (and I remember problems like this in Differential Equations), but I thought those were just to make the math more complicated, not based in reality... So is it the weight of the liquid remaining above the hole that is the source of the pressure (i.e., would it be the same if the top of the tank were open), or is it the air pressure in the tank as the volume of liquid decreases and volume of air increases? [[User:Mathmannix|Mathmannix]] ([[User talk:Mathmannix|talk]]) 11:08, 21 August 2024 (UTC)&lt;br /&gt;
:A sealed-top would change the dynamics (like trying to pour the contents of a 2 litre (or whatever the US equivalent is) pop/soda bottle, it will tend to 'glug glug glug' intermittently unless you: a) incline the bottle to allow an optimum amount lf free akr back into the emltying bottle or, b) initialise the up-ended emptying with a spin sufficient to create a 'waterspout' effect up through which the replacement air can (more) freely pass.&lt;br /&gt;
:Though there are other possible factors, in that example, including the potential pressure of any self-releasing carbonation pressure (e.g. giving the bottle a shake, or a foreign body, before releasing the 'pour') and/or squeezing/'milking' the soft plastic container strategically to create another form of pressurised expulsion.&lt;br /&gt;
:For the 'classical' problem, one should probably assume sufficient inward venting (either an open/part-open top or a second hole drilled near the top to effect this purpose) as well as a reasonably unexotic liquid (neither molasses, cornstarch-mixture, anything that is actually a very fine dry powder, anything that reacts significantly with/upon air, any liquid very close to its vapour-point nor ''specifically'' supercooled helium) or any additional elements (stirrers, baffles, spongey inners, inner membranes or the contents being a layered combination of imiscable liquids of different densities that may or may not react slightly all across the interface plane). Most things that aren't actually exotic (and even a few that are, and might warrant a warning /¡\) are close enough to water to treat as if just that, at least under the further assumption that we're working at or around Standard Temperature and Pressure. But a slightly different density, viscosity and surface tension (plus the nature of the container, e.g. extreme hydrophilic or hydrophobic inner coatings where water is involved) ''could'' (in combination) drastically change the actual outcome given enough of the right kind of simultaneous differences imparted.

&lt;br /&gt;
In order to remove calculus from the scenario one needs a pressurization system that keeps Pair + Pliquid, constant at the hole.  This requires sensing the height of the liquid surface and increasing the air pressure as the surface drops, the relationship depending on the density of the liquid.

I wish my maths teachers back in the day had come up with any examples like this and I might have got a notion that calculus can be good for something after all, that there is an actual justification of learning it. I still might have failed in grasping it, mind you, but at least I'd have the decency to feel just a tiny little bit bad about it. I realise this is probably making me the odd one out here, but I felt I should mention it because it's linked to a fundamental problem of teaching - teaching anything at all, not just maths: most of the time you need to sell to your students the notion that knowledge and skills outside of your fields of interests, those that certainly don't relate to any career you have in mind for yourself, are valuable enough to justify the pain of learning them. You see, generations of &amp;quot;dumb&amp;quot;, &amp;quot;lazy&amp;quot; students like I used to be myself have got it right on instinct: anything complex and abstract is literally painful to learn. Thinking hard in fact generally hurts, even if you pretend to yourself you like it (as I do, too, but what we really like are the results we come up with when we're done). Psychologists recently hammered this fact home in a large meta study [https://www.ru.nl/en/research/research-news/thinking-hard-hurts] [https://psycnet.apa.org/doiLanding?doi=10.1037%2Fbul0000443]). So with something as complex and abstract as calculus, you'll have to sell to them it's worth learning anyway, even despite a very real prospect of being able to live a perfectly happy and successful life without it, and if it's only of the weak basis of &amp;quot;it may still turn out to come in handy at some point&amp;quot;. I'm a teacher myself, in case you're wondering, and if I taught maths and calculus and suchlike, transferring to it the same &amp;quot;signature&amp;quot; hands-on approach I'm somewhat known for using in geography, it'd be quite possible you'd see me drill an actual hole into an actual barrel (and likely make a show of installing a tap to make it reusable, too).

If the tank were sufficiently pressurized, they might end up having to mop up careless calculus teachers.

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|The title text isn't explained}}&lt;br /&gt;
This is the seventh comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #45: Exterior Kansas.&lt;br /&gt;
&lt;br /&gt;
[[File:Exterior_Kansas_Azimuthal_Projection.png|thumb|left|Projection of the world from the same perspective as the comic. This uses an azimuthal equidistant projection, so distances from the center point (39°50′S 98°35′E) are correct but areas are distorted.]]&lt;br /&gt;
&lt;br /&gt;
This comic portrays an unusual projection of a map of the contiguous United States based loosely on an {{w|azimuthal projection}}. Maps of individual countries are common, especially in academic settings. It is typical for such maps, which only display a limited area of the globe, to use a projection that does not severely distort the shape of the country or its internal borders, but a country that is large enough (as with the United States) will always noticeably suffer from certain distortions of at least one element chosen from distances, areas or angles. This usually occurs at its extremities (though some projections can be made more faithful to its extremities at the expense of distorting its interior). &lt;br /&gt;
&lt;br /&gt;
Here, however, Randall has opted for a much different projection. Rather than placing the geographical center of the country in the middle and the borders on the outside, this map has gone the opposite direction, with the border of the US toward the center, and the geographical center of the contiguous US (Kansas) and surrounding states distorted to surround the entire map. This, understandably, results in the shape of both the national and state borders being largely unrecognizable as it effectively puts ''every'' bit of the chosen map features out towards the distorted extremities. Much of the internal area of Kansas itself (should one wish to display further internal features) may be located far beyond the comic's edges, perhaps even to infinitely far away on the projected plane.&lt;br /&gt;
&lt;br /&gt;
[[File:Azimuthal_equidistant_projection_SW.jpg|300px|thumb|right|Polar {{w|azimuthal equidistant projection}}, as on the {{w|flag of the United Nations}}, but with an &amp;quot;exterior Antarctica&amp;quot;]]&lt;br /&gt;
&lt;br /&gt;
If Alaska and Hawaii were present in this map and represented in geographically accurate locations (as opposed to inset, as is common in many maps of the United States), Alaska would in the upper right of the empty space, between Minnesota and Washington, while Hawaii would be in the center to the right, off the coast of California. Both would be rather small, with Hawaii particularly compressed (to an extent dictated by the exact projection method used). Additionally, if all 50 states were included, the geographical center would be further to the northwest, resulting in an &amp;quot;Exterior South Dakota&amp;quot; projection.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the fact that {{w|Geographic center of the United States#Contiguous United States|the geographic center of the contiguous United States}} is within Kansas. This map projection instead causes Kansas to show up as the exterior of the US, which makes it the outer edge.&lt;br /&gt;
&lt;br /&gt;
The statement that ''topologists now believe it's actually their outer edge'' plays with the notion that map projections influence your perspective on the world, as it is known to be the case with more familiar examples like Mercator vs. Gall-Peters projections, or world maps with the South Pole on top and so on. Similarly, or so the claim goes, any notions of interior and edge may just be a matter of perspective.&lt;br /&gt;
If you were to enclose a small square in four walls, but define this to be the outside, you'd effectively create a roofless building of which the floor area encompasses almost the entire surface of the Earth (minus the small square) - see ''So Long And Thanks For All The Fish'' by Douglas Adams for a classic example of this gag. Randall has always been fond of exploring how map projections influence our perspective both in a parodistic way and by playing it straight, e.g. in: [[503: Terminology]], [[977: Map Projections]], or [[2838: Dubious Islands]]&lt;br /&gt;
&lt;br /&gt;

: As the center of the map corresponds to Kansas' antipode (Kerguelen in the Indian Ocean https://www.geodatos.net/en/antipodes/united-states/kansas-city), Hawaii isn't really &amp;quot;near the center&amp;quot;, but rather to the right of the center (in the direction of the &amp;quot;Pacific Ocean&amp;quot; tag). --[[Special:Contributions/162.158.86.100|162.158.86.100]] 05:58, 27 June 2024 (UTC)&lt;br /&gt;

== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use. If it's a near-side orthographic projection and, say approaching +1 radii up from the surface-tangent, then it could perhaps be 'over the horizon' in the direct projection and thus 'beyond the singularity' of the inverted-radius version.)&lt;br /&gt;
:I'd have to mess with some map data, to be sure the existing features fit either idea of projection (or find the actual one (ab)used), but this'd probably be what I'd do, straight off the bat. And then I could apply it to extraterratorial features, also. I've got some of the necessary data and mungable code handily sitting on a machine that I am ''unhandily'' not going to next use until at least the weekend, and reimplimenting it on this tablet would mean starting from first principles again/testing/etc... ;) [[Special:Contributions/172.70.163.120|172.70.163.120]] 09:23, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Check out the Wikipedia article &amp;quot;Azimuthal equidistant projection&amp;quot; and scroll to &amp;quot;Sample azimuthal equidistant projection maps&amp;quot;. There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the &amp;quot;great sea&amp;quot; of Randall's map, using a similar projection.

: Yay! A task for a geography teacher (i.e. me, and I'm a big fan of Randall's work with maps), and I just happen to have the right bookmarks for this kind of thing in my browser. So here's a little toy to play around with: [https://www.worldmapgenerator.com/en/wizard/step/centering/?config=eyJpZCI6IkNVU1RPTV9XSVpBUkQiLCJsYXllcklkcyI6WyJDTElQX1BBVEgiLCJCQUNLR1JPVU5EIiwiU1BIRVJFIiwiR1JBVElDVUxFUyIsIkxBTkQiLCJPQ0VBTiJdLCJwcm9qZWN0aW9uSWQiOiJBWklNVVRIQUxfRVFVSURJU1RBTlQiLCJyZW5kZXJpbmdBZGFwdGVySWQiOiJDQU5WQVMiLCJtYXBUaGVtZUlkIjoiREVGQVVMVCIsImNlbnRlciI6WzAsMF0sInJvdGF0aW9uIjpbLTgxLDQwLDBdLCJ6b29tIjowLjksIndpemFyZFN0ZXBQcm9ncmVzc0lkeCI6MywidmVyc2lvbiI6IjEuMC4wIn0%3D] I hope my settings got preserved in the link as they should, else whoever added all those letters and numbers clearly has something to answer for! If the link works as it should it'll show you what a map of the whole wide world would look like in an Azimuthal Equidistant Projection with Kansas on the exterior. That is, I first used this Antipodes Map [https://www.antipodesmap.com] to locate the point opposite to Lebanon, Kansas at 39°48'35&amp;quot;S, 81°26'39.8&amp;quot;E , which is quite literally in the middle of the Indian Ocean, near the islands of Saint Paul and Nouvelle Amsterdam (which, incidentally, belong to France and are mainly known for being as far away from anything as you can possibly get on this planet*) and then set the centre of the worldmapgenerator.com map approximately there. It's not a very precise tool, but it'll do - it's precise enough for me to use in lessons anyway. Surprisingly, you actually get a more or less usable map for much of the world (if you're not too fussy or trying to navigate with it or anything), ''except only'' for North and Middle America. :D [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 16:04, 27 June 2024 (UTC)&lt;br /&gt;

Me being a geomatician and having a couple of friends who are map projection nerds, we had a short discussion (https://mastodon.social/@EvenRouault/112688667438256248) and I ended up implementing a web map version of a Oblique Stereographic map in the style of this: https://ivan.sanchezortega.es/2024-06-exterior-kansas/ .  You'll notice that a Oblique Stereographic projection does create a coastline that matches the one in the comic much closer to the Azimuthal Equidistant projection (and therefore, I'll hypothesize that Randall used a compromise projection). I'd like to add an image of my map to this explanation, but I seem to lack permissions. [[User:Ivansanchez|Ivansanchez]] ([[User talk:Ivansanchez|talk]]) 14:47, 29 June 2024 (UTC)&lt;br /&gt;

==Explanation==&lt;br /&gt;
{{incomplete|The title text isn't explained}}&lt;br /&gt;
This is the seventh comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #45: Exterior Kansas.&lt;br /&gt;
&lt;br /&gt;
[[File:Exterior_Kansas_Azimuthal_Projection.png|thumb|left|Projection of the world from the same perspective as the comic. This uses an azimuthal equidistant projection, so distances from the center point (39°50′S 98°35′E) are correct but areas are distorted.]]&lt;br /&gt;
&lt;br /&gt;
This comic portrays an unusual projection of a map of the contiguous United States based loosely on an {{w|azimuthal projection}}. Maps of individual countries are common, especially in academic settings. It is typical for such maps, which only display a limited area of the globe, to use a projection that does not severely distort the shape of the country or its internal borders, but a country that is large enough (as with the United States) will always noticeably suffer from certain distortions of at least one element chosen from distances, areas or angles. This usually occurs at its extremities (though some projections can be made more faithful to its extremities at the expense of distorting its interior). &lt;br /&gt;
&lt;br /&gt;
Here, however, Randall has opted for a much different projection. Rather than placing the geographical center of the country in the middle and the borders on the outside, this map has gone the opposite direction, with the border of the US toward the center, and the geographical center of the contiguous US (Kansas) and surrounding states distorted to surround the entire map. This, understandably, results in the shape of both the national and state borders being largely unrecognizable as it effectively puts ''every'' bit of the chosen map features out towards the distorted extremities. Much of the internal area of Kansas itself (should one wish to display further internal features) may be located far beyond the comic's edges, perhaps even to infinitely far away on the projected plane.&lt;br /&gt;
&lt;br /&gt;
[[File:Azimuthal_equidistant_projection_SW.jpg|300px|thumb|right|Polar {{w|azimuthal equidistant projection}}, as on the {{w|flag of the United Nations}}, but with an &amp;quot;exterior Antarctica&amp;quot;]]&lt;br /&gt;
&lt;br /&gt;
If Alaska and Hawaii were present in this map and represented in geographically accurate locations (as opposed to inset, as is common in many maps of the United States), Alaska would in the upper right of the empty space, between Minnesota and Washington, while Hawaii would be in the center to the right, off the coast of California. Both would be rather small, with Hawaii particularly compressed (to an extent dictated by the exact projection method used). Additionally, if all 50 states were included, the geographical center would be further to the northwest, resulting in an &amp;quot;Exterior South Dakota&amp;quot; projection.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the fact that {{w|Geographic center of the United States#Contiguous United States|the geographic center of the contiguous United States}} is within Kansas. This map projection instead causes Kansas to show up as the exterior of the US, which makes it the outer edge.&lt;br /&gt;
&lt;br /&gt;
The statement that ''topologists now believe it's actually their outer edge'' plays with the notion that map projections influence your perspective on the world, as it is known to be the case with more familiar examples like Mercator vs. Gall-Peters projections, or world maps with the South Pole on top and so on. Similarly, or so the claim goes, any notions of interior and edge may just be a matter of perspective.&lt;br /&gt;
If you were to enclose a small square in four walls, but define this to be the outside, you'd effectively create a roofless building of which the floor area encompasses almost the entire surface of the Earth (minus the small square) - see ''So Long And Thanks For All The Fish'' by Douglas Adams for a classic example of this gag. Randall has always been fond of exploring the way map projections influence our perspective both in a parodistic way and by playing it straight, e.g. in: [[503: Terminology]], [[977: Map Projections]], or [[2838: Dubious Islands]]&lt;br /&gt;

This is the seventh comic in the series of [[:Category:Bad Map Projections|Bad Map Projections]] displaying Bad Map Projection #45: Exterior Kansas.&lt;br /&gt;
&lt;br /&gt;
[[File:Exterior_Kansas_Azimuthal_Projection.png|thumb|left|Projection of the world from the same perspective as the comic. This uses an azimuthal equidistant projection, so distances from the center point (39°50′S 98°35′E) are correct but areas are distorted.]]&lt;br /&gt;

&lt;br /&gt;

This map projection instead causes Kansas to show up as the exterior of the US, which makes it the outer edge.&lt;br /&gt;
he statement that ''topologists now believe it's actually their outer edge'' draws on the same concept as Wonko the Sane's house in ''So Long And Thanks For All The Fish'' by Douglas Adams. Said house has its outer walls on the inside, declaring the rest of the world to be inside an asylum for its own safety. By challenging common notions about what's outside and inside by a radical change of perspective Wonko the Sane effectively constructed a building with the floor area of almost the entire Earth's surface (works only on 3D-surfaces like a planet). Similarly, this map projection seems to declare that you can see geographical centre of the USA as their outer edge, if you just change your perspective. The map projections we're familiar with may have a great influence on our perspective on the world (cf. Mercator vs. Gall-Peters projections, Winkel-Triple projection centred on China, Australian world map with South on top, and so on), a topic Randall has always been fond of exploring both in a parodistic way or playing it straight, e.g.: [[https://www.explainxkcd.com/wiki/index.php/503:_Terminology]][[https://www.explainxkcd.com/wiki/index.php/977:_Map_Projections]][[https://www.explainxkcd.com/wiki/index.php/2838:_Dubious_Islands]]&lt;br /&gt;

Seems weird that it's just the contiguous US, with &amp;quot;hints&amp;quot; about what lies within.  I hope Randall will release another version with the rest of the world included.[[Special:Contributions/162.158.158.61|162.158.158.61]] 03:20, 27 June 2024 (UTC)&lt;br /&gt;

Would the center be both poles ''and'' Kansas's antipode? --[[Special:Contributions/172.68.27.150|172.68.27.150]] 03:58, 27 June 2024 (UTC)&lt;br /&gt;

: As the center of the map corresponds to Kansas' antipode (Kerguelen in the Indian Ocean https://www.geodatos.net/en/antipodes/united-states/kansas-city), Hawaii isn't really &amp;quot;near the center&amp;quot;, but rather to the right of the center (in the direction of the &amp;quot;Pacific Ocean&amp;quot; tag). --[[Special:Contributions/162.158.86.100|162.158.86.100]] 05:58, 27 June 2024 (UTC)&lt;br /&gt;

'''To make the explanation of the title text more complete:''' The statement that ''topologists now believe it's actually their outer edge'' seems to allude to a concept similar to that behind Wonko the Sane's house in ''So Long And Thanks For All The Fish'' by Douglas Adams. Said house has its outer walls on the inside, declaring the rest of the world to be inside an asylum for its own safety. By challenging common notions about what's outside and inside by a radical change of perspective Wonko the Sane effectively constructed a building with the floor area of almost the entire Earth's surface. Similarly, this map projection seems to declare that you can see geographical centre of the USA as their outer edge, if you just change your perspective a little. The map projections we're familiar with may have a great influence on our perspective on the world (cf. Mercator vs. Gall-Peters projections, Winkel-Triple projection centred on China, Australian world map with South on top, and so on), a topic that I believe Randall has always been fond of exploring both in a parodistic way or playing it straight. [https://www.explainxkcd.com/wiki/index.php/503:_Terminology][https://www.explainxkcd.com/wiki/index.php/2082:_Mercator_Projection][https://www.explainxkcd.com/wiki/index.php/977:_Map_Projections][https://www.explainxkcd.com/wiki/index.php/1799:_Bad_Map_Projection:_Time_Zones][https://www.explainxkcd.com/wiki/index.php/2489:_Bad_Map_Projection:_The_Greenland_Special][https://www.explainxkcd.com/wiki/index.php/2807:_Bad_Map_Projection:_ABS(Longitude)][https://www.explainxkcd.com/wiki/index.php/1389:_Surface_Area][https://www.explainxkcd.com/wiki/index.php/2838:_Dubious_Islands][https://www.explainxkcd.com/wiki/index.php/850:_World_According_to_Americans][https://www.explainxkcd.com/wiki/index.php/1500:_Upside-Down_Map]. So, what do you think of this as an addition? [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 13:55, 25 August 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use. If it's a near-side orthographic projection and, say approaching +1 radii up from the surface-tangent, then it could perhaps be 'over the horizon' in the direct projection and thus 'beyond the singularity' of the inverted-radius version.)&lt;br /&gt;
:I'd have to mess with some map data, to be sure the existing features fit either idea of projection (or find the actual one (ab)used), but this'd probably be what I'd do, straight off the bat. And then I could apply it to extraterratorial features, also. I've got some of the necessary data and mungable code handily sitting on a machine that I am ''unhandily'' not going to next use until at least the weekend, and reimplimenting it on this tablet would mean starting from first principles again/testing/etc... ;) [[Special:Contributions/172.70.163.120|172.70.163.120]] 09:23, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Check out the Wikipedia article &amp;quot;Azimuthal equidistant projection&amp;quot; and scroll to &amp;quot;Sample azimuthal equidistant projection maps&amp;quot;. There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the &amp;quot;great sea&amp;quot; of Randall's map, using a similar projection.

: Yay! A task for a geography teacher (i.e. me, and I'm a big fan of Randall's work with maps), and I just happen to have the right bookmarks for this kind of thing in my browser. So here's a little toy to play around with: [https://www.worldmapgenerator.com/en/wizard/step/centering/?config=eyJpZCI6IkNVU1RPTV9XSVpBUkQiLCJsYXllcklkcyI6WyJDTElQX1BBVEgiLCJCQUNLR1JPVU5EIiwiU1BIRVJFIiwiR1JBVElDVUxFUyIsIkxBTkQiLCJPQ0VBTiJdLCJwcm9qZWN0aW9uSWQiOiJBWklNVVRIQUxfRVFVSURJU1RBTlQiLCJyZW5kZXJpbmdBZGFwdGVySWQiOiJDQU5WQVMiLCJtYXBUaGVtZUlkIjoiREVGQVVMVCIsImNlbnRlciI6WzAsMF0sInJvdGF0aW9uIjpbLTgxLDQwLDBdLCJ6b29tIjowLjksIndpemFyZFN0ZXBQcm9ncmVzc0lkeCI6MywidmVyc2lvbiI6IjEuMC4wIn0%3D] I hope my settings got preserved in the link as they should, else whoever added all those letters and numbers clearly has something to answer for! If the link works as it should it'll show you what a map of the whole wide world would look like in an Azimuthal Equidistant Projection with Kansas on the exterior. That is, I first used this Antipodes Map [https://www.antipodesmap.com] to locate the point opposite to Lebanon, Kansas at 39°48'35&amp;quot;S, 81°26'39.8&amp;quot;E , which is quite literally in the middle of the Indian Ocean, near the islands of Saint Paul and Nouvelle Amsterdam (which, incidentally, belong to France and are mainly known for being as far away from anything as you can possibly get on this planet*) and then set the centre of the worldmapgenerator.com map approximately there. It's not a very precise tool, but it'll do - it's precise enough for me to use in lessons anyway. Surprisingly, you actually get a more or less usable map for much of the world (if you're not too fussy or trying to navigate with it or anything), ''except only'' for North and Middle America. :D [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 16:04, 27 June 2024 (UTC)&lt;br /&gt;

:::: Yeah, I'll accept Cookies if essential, but often they aren't, so it's not even a very good joke to make. Maybe they do just do everything in URL-encoded/GET data.

It's frightening how many 'interested parties' are potentially getting info (dozens to hundreds, at a time).

Me being a geomatician and having a couple of friends who are map projection nerds, we had a short discussion (https://mastodon.social/@EvenRouault/112688667438256248) and I ended up implementing a web map version of a Oblique Stereographic map in the style of this: https://ivan.sanchezortega.es/2024-06-exterior-kansas/ .  You'll notice that a Oblique Stereographic projection does create a coastline that matches the one in the comic much closer to the Azimuthal Equidistant projection (and therefore, I'll hypothesize that Randall used a compromise projection).

The symmetry of the truss intrigues me. Struts that are diagonal across the faces of the cuboids is normal, but is it a real thing to also use the body diagonal? Never seen that IRL, not sure if it makes sense from the statics. --[[Special:Contributions/172.70.247.82|172.70.247.82]] 22:16, 19 August 2024 (UTC)&lt;br /&gt;
: Struts as shown provide some left-right stability, but not as effectively as struts across the face would.  They also provide some redundant front-back stability with the struts running along the faces. [[Special:Contributions/172.68.71.90|172.68.71.90]] 14:47, 21 August 2024 (UTC)&lt;br /&gt;
: I mentally modeled the flexibility modes, and it very much depends upon whether the verticals are solid (with their resistence to bending playing a big part alongside the incident horizontals'/diagonals' exactvmethod of attachment) or are just sections of rod between a suitable receiver-'node' at each junction.&lt;br /&gt;
: in particular, the strength of any one of the three 'boxes' (each level between adjacent horizontal cross-sectional perimeters) is somewhat less secure, as a single level can 'fold' sideways over each side's vertical-diagonal strut (along with the respective front/back horizontals, held 'square' by the internal cross-brscing). Only the continuation and linking with the other 'boxes' really guarantees any innate stability, and if each node is free-twisting then the likely first result of any failure is that the tower topples forwards and/or backwards as it folds up due to the unbraced facing and hindside quadrilaterals.&lt;br /&gt;
: But it does depend a lot upon the exact nature of the linkages (which can only be guessed at), and other failure-modes could involve node-slippage if they merely grip the cross-braces to the entirely top-to-bottom poles and there's potential for sliding there instead of primarily rotation (or over-stressed failure in any given length of rod).&lt;br /&gt;
: The support (or additional pressure) provided by the access staircase is also probably a factor. It could even be the most important bit in holding it up! ...if firmly anchored at the other end and robust enough in itself.&lt;br /&gt;
: I'd definitely add other diagonals (including opposite-type body-diagonals, perhaps tied to the existing one as they pass right across each other), just to be sure. The more the better, of course, but there's probably a limit through diminishing concerns. And too many diagonals primarily in a helical pattern could concentrate forces into a particular type of rotational failure if you also add too much brace-weight in doing so.

As a mathematician, I'm surprised I didn't know about this idea. (It's definitely not my field!) I actually thought the flow would be constant, an algebraic problem. Oh, I'm sure I saw these types of problems in Calculus (and I remember problems like this in Differential Equations), but I thought those were just to make the math more complicated, not based in reality... So is it the weight of the liquid remaining above the hole that is the source of the pressure (i.e., would it be the same if the top of the tank were open), or is it the air pressure in the tank as the volume of liquid decreases and volume of air increases? [[User:Mathmannix|Mathmannix]] ([[User talk:Mathmannix|talk]]) 11:08, 21 August 2024 (UTC)&lt;br /&gt;
:A sealed-top would change the dynamics (like trying to pour the contents of a 2 litre (or whatever the US equivalent is) pop/soda bottle, it will tend to 'glug glug glug' intermittently unless you: a) incline the bottle to allow an optimum amount lf free akr back into the emltying bottle or, b) initialise the up-ended emptying with a spin sufficient to create a 'waterspout' effect up through which the replacement air can (more) freely pass.&lt;br /&gt;
:Though there are other possible factors, in that example, including the potential pressure of any self-releasing carbonation pressure (e.g. giving the bottle a shake, or a foreign body, before releasing the 'pour') and/or squeezing/'milking' the soft plastic container strategically to create another form of pressurised expulsion.&lt;br /&gt;
:For the 'classical' problem, one should probably assume sufficient inward venting (either an open/part-open top or a second hole drilled near the top to effect this purpose) as well as a reasonably unexotic liquid (neither molasses, cornstarch-mixture, anything that is actually a very fine dry powder, anything that reacts significantly with/upon air, any liquid very close to its vapour-point nor ''specifically'' supercooled helium) or any additional elements (stirrers, baffles, spongey inners, inner membranes or the contents being a layered combination of imiscable liquids of different densities that may or may not react slightly all across the interface plane). Most things that aren't actually exotic (and even a few that are, and might warrant a warning /¡\) are close enough to water to treat as if just that, at least under the further assumption that we're working at or around Standard Temperature and Pressure. But a slightly different density, viscosity and surface tension (plus the nature of the container, e.g. extreme hydrophilic or hydrophobic inner coatings where water is involved) ''could'' (in combination) drastically change the actual outcome given enough of the right kind of simultaneous differences imparted.

In order to remove calculus from the scenario one needs a pressurization system that keeps Pair + Pliquid, constant at the hole.

I wish my maths teachers back in the day had come up with any examples like this and I might have got a notion that calculus can be good for something after all, that there is an actual justification of learning it. I still might have failed in grasping it, mind you, but at least I'd have the decency to feel just a tiny little bit bad about it. I realise this is probably making me the odd one out here, but I felt I should mention it because it's linked to a fundamental problem of teaching - teaching anything at all, not just maths: most of the time you need to sell to your students the notion that knowledge and skills outside of your fields of interests, those that certainly don't relate to any career you have in mind for yourself, are valuable enough to justify the pain of learning them. You see, generations of &amp;quot;dumb&amp;quot;, &amp;quot;lazy&amp;quot; students like I used to be myself have got it right on instinct: anything complex and abstract is literally painful to learn. Thinking hard in fact generally hurts, even if you pretend to yourself you like it (as I do, too, but what we really like are the results we come up with when we're done). Psychologists recently hammered this fact home in a large meta study [https://www.ru.nl/en/research/research-news/thinking-hard-hurts] [https://psycnet.apa.org/doiLanding?doi=10.1037%2Fbul0000443]). So with something as complex and abstract as calculus, you'll have to sell to them it's worth learning anyway, even despite a very real prospect of being able to live a perfectly happy and successful life without it, and if it's only of the weak basis of &amp;quot;it may still turn out to come in handy at some point&amp;quot;. I'm a teacher myself, in case you're wondering, and if I taught maths and calculus and suchlike, transferring to it the same &amp;quot;signature&amp;quot; hands-on approach I'm somewhat known for using in geography, it'd be quite possible you'd see me drill an actual hole into an actual barrel (and likely make a show of installing a tap to make it reusable, too).

The symmetry of the truss intrigues me. Struts that are diagonal across the faces of the cuboids is normal, but is it a real thing to also use the body diagonal? Never seen that IRL, not sure if it makes sense from the statics. --[[Special:Contributions/172.70.247.82|172.70.247.82]] 22:16, 19 August 2024 (UTC)&lt;br /&gt;
: Struts as shown provide some left-right stability, but not as effectively as struts across the face would.  They also provide some redundant front-back stability with the struts running along the faces. [[Special:Contributions/172.68.71.90|172.68.71.90]] 14:47, 21 August 2024 (UTC)&lt;br /&gt;
: I mentally modeled the flexibility modes, and it very much depends upon whether the verticals are solid (with their resistence to bending playing a big part alongside the incident horizontals'/diagonals' exactvmethod of attachment) or are just sections of rod between a suitable receiver-'node' at each junction.&lt;br /&gt;
: in particular, the strength of any one of the three 'boxes' (each level between adjacent horizontal cross-sectional perimeters) is somewhat less secure, as a single level can 'fold' sideways over each side's vertical-diagonal strut (along with the respective front/back horizontals, held 'square' by the internal cross-brscing). Only the continuation and linking with the other 'boxes' really guarantees any innate stability, and if each node is free-twisting then the likely first result of any failure is that the tower topples forwards and/or backwards as it folds up due to the unbraced facing and hindside quadrilaterals.&lt;br /&gt;
: But it does depend a lot upon the exact nature of the linkages (which can only be guessed at), and other failure-modes could involve node-slippage if they merely grip the cross-braces to the entirely top-to-bottom poles and there's potential for sliding there instead of primarily rotation (or over-stressed failure in any given length of rod).&lt;br /&gt;
: The support (or additional pressure) provided by the access staircase is also probably a factor. It could even be the most important bit in holding it up! ...if firmly anchored at the other end and robust enough in itself.&lt;br /&gt;
: I'd definitely add other diagonals (including opposite-type body-diagonals, perhaps tied to the existing one as they pass right across each other), just to be sure. The more the better, of course, but there's probably a limit through diminishing concerns. And too many diagonals primarily in a helical pattern could concentrate forces into a particular type of rotational failure if you also add too much brace-weight in doing so.

{{incomplete|Created by a TIME TRAVELLING BOT WITH NO CELL SERVICE IN THE PROTOZOIC ERA- Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Time travel is a common sci-fi/fantasy plot, in which someone from one era is sent forward or backward in time to another era. Normally, the travel itself goes off without a hitch, with the usual threats to the time traveler being what happens at some point ''after'' they arrive at their destination. More rarely, a time traveler might immediately encounter some hazard because of where their time travel method has deposited them.&lt;br /&gt;
&lt;br /&gt;
This comic takes the latter situation to the extreme, observing different causes of death for potential time travelers through the ages based on the geologic evolution of earth, from its formation over 4 billion years ago to the present, see detailed explanation in the [[#Table of death causes|table]]. The chart only shows the most likely cause for a given period of time, although the title text shows that there may always be others possible.&lt;br /&gt;
&lt;br /&gt;
The title text suggests that an alternative fate within the &amp;quot;eaten by fish&amp;quot; era is the exact opposite. Seafood allergies are not unknown in the present day and, having fortuitously avoided the primary &amp;quot;Starving&amp;quot; fate from the prior era, it may be that the traveler tries eating a &amp;quot;fish&amp;quot;, in this case not a fish but a {{w|trilobite}} a kind of shellfish, and finds that ''either'' some existing allergy is just as applicable to the prehistoric ancestors of shellfish ''or'' that the flesh of the creatures of that age spark off an allergic condition that (as a modern human) they were not previously aware of. &lt;br /&gt;
&lt;br /&gt;
The former might be the one intended, as a person with a known shellfish (or lactose, or peanut, etc) allergy might double-check the possible presence of a problematic ingredient in a potential snack by referencing online resources; a facility that is claimed not to be available, here, with the smartphone stuck in the past, long before any reliable phone-service/wifi is available to connect to. Otherwise, suspecting the food has not agreed with them, they are now denied access to the best online information on how to properly treat their symptoms.&lt;br /&gt;

! Scope=“col” | Time frame&lt;br /&gt;
! scope=&amp;quot;col&amp;quot; | Explanation&lt;br /&gt;
|-&lt;br /&gt;
| Lava || Earth Forms || During the formation of the Earth, the surface was a hellish landscape of lava. &lt;br /&gt;
|-&lt;br /&gt;
| Asphyxiation || 4 billion years ago || Before {{w|cyanobacteria}} started photosynthesising and producing oxygen, the atmosphere of the Earth was mainly composed of hydrogen sulphide, methane, and carbon dioxide. Humans need oxygen to breathe.{{citation needed}}&lt;br /&gt;
|-&lt;br /&gt;
| Meteors || 3.9 billion years ago || During the {{w|Late Heavy Bombardment}}, the Earth's surface was subjected to a large number of asteroid and comet impacts, destroying much of Earth's early crust.&lt;br /&gt;
|-&lt;br /&gt;
| Asphyxiation || 3 billion years ago || According to the table the heavy bombardment was so severe that this would be the most likely cause of death during a period, where there where still no oxygen, as shown by the death by asphyxiation also long after the meteors returned to normal level. However, even when these meteors came at an alarming rate, the chance of being hit by one of these before asphyxiation in an atmosphere without any oxygen seems remote. Of course if the time machine had some oxygen along with it, and the reason people died from lack of oxygen was that they stayed put for a long time, before their supply ran out, a meteor might have a chance. However, this would then be on the assumption that the time travlers cannot travel back to the present. If they do not die quickly upon arrival, then why could they then not return. Of course this discussion is only relevant if time travel was actually possible.&lt;br /&gt;
|-&lt;br /&gt;
| Slightly slower asphyxiation || 2 billion years ago|| Cyanobacteria had started photosynthesising, leading to the {{w|Great Oxygenation Event|Oxygen Catastrophe}}, but the oxygen levels weren’t high enough to support human life. &lt;br /&gt;
|-&lt;br /&gt;
| Freezing || Less than 1 billion years ago || During the {{w|Cryogenian|Cryogenian Ice Age}}, the Earth’s temperature fell to -12°C, much too cold to support human life if not properly prepared.&lt;br /&gt;
|-&lt;br /&gt;
| Starving || 600 to 485 million years ago || During this time, the temperature was mild and comfortable; however, the only life during this time was single-cell organisms and – especially later – tiny multicellular organisms, which humans cannot eat or would not tolerate.&lt;br /&gt;
|-&lt;br /&gt;
| Eaten by fish || 485 to 250 million years ago || During the {{w|Great Ordovician Biodiversification Event}} and subsequent times, fish {{w|Evolution of fish|evolved jaws}} and some species grew quite large.&lt;br /&gt;
|-&lt;br /&gt;
| Trampled || 252 to 66 million years ago || The {{w|Mesozoic Era}} is often called the “Age of Dinosaurs.&amp;quot; The majority of these dinosaurs were herbivorous and many were quite large, so being eaten would be less likely than being trampled on.&lt;br /&gt;
Note that this is an almost exact inversion of what happens in the classic story ''{{w|A Sound of Thunder}}'', in which the traveler survives personally unscathed but tramples an 'age of dinosaur' creature (to unfortunate effect).&lt;br /&gt;
|-&lt;br /&gt;
| Eaten by mammals || 66 million years ago to sometime before now || The {{w|Cenozoic Era}}, which began 66 million years ago, is often referred to as the &amp;quot;Age of Mammals&amp;quot;. Though some eras have more likely causes of death (such as wars, but that would basically be during the &amp;quot;Now&amp;quot; period in the table), overall being eaten by large mammals is probably the biggest risk.&lt;br /&gt;
|-&lt;br /&gt;
| Time machine door gets stuck || Roughly present day || As the timeline approaches the present day, the conditions on Earth become more than suitable enough for a human time traveler to survive extended periods of time &amp;amp;mdash; as evidenced by the fact hominids and early humans begin to emerge. As such there's nothing else more likely to kill them than getting stuck in the time machine and starving (or, if the time machine is air-tight, asphyxiating). This assumes the Time Machine is also a {{w|Faraday Cage}} (that can block the signal of an emergency call) or the traveler doesn't take their phone with them, although the title text indicates they will. Or that the now extends back before cell phones, maybe covering the entire period of human civilization.&lt;br /&gt;

Seems weird that it's just the contiguous US, with &amp;quot;hints&amp;quot; about what lies within.  I hope Randall will release another version with the rest of the world included.[[Special:Contributions/162.158.158.61|162.158.158.61]] 03:20, 27 June 2024 (UTC)&lt;br /&gt;

Would the center be both poles ''and'' Kansas's antipode? --[[Special:Contributions/172.68.27.150|172.68.27.150]] 03:58, 27 June 2024 (UTC)&lt;br /&gt;

&lt;br /&gt;
: As the center of the map corresponds to Kansas' antipode (Kerguelen in the Indian Ocean https://www.geodatos.net/en/antipodes/united-states/kansas-city), Hawaii isn't really &amp;quot;near the center&amp;quot;, but rather to the right of the center (in the direction of the &amp;quot;Pacific Ocean&amp;quot; tag). --[[Special:Contributions/162.158.86.100|162.158.86.100]] 05:58, 27 June 2024 (UTC)&lt;br /&gt;

I don't think the middle part is meant to be seen as 'water', just 'out of scope'. [[User:Jaap-Jan|Jaap-Jan]] ([[User talk:Jaap-Jan|talk]]) 07:44, 27 June 2024 (UTC)&lt;br /&gt;
:Yeah, this is similar to a map like https://suncatcherstudio.com/uploads/patterns/us-maps/pdf-png/usa-map-states-names-color-010101.png  In that map, Canada and Mexico aren't &amp;quot;rendered as water&amp;quot;, they're not rendered at all, and neither are the oceans.  I'm going to edit that. [[Special:Contributions/162.158.78.73|162.158.78.73]] 13:34, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use. If it's a near-side orthographic projection and, say approaching +1 radii up from the surface-tangent, then it could perhaps be 'over the horizon' in the direct projection and thus 'beyond the singularity' of the inverted-radius version.)&lt;br /&gt;
:I'd have to mess with some map data, to be sure the existing features fit either idea of projection (or find the actual one (ab)used), but this'd probably be what I'd do, straight off the bat. And then I could apply it to extraterratorial features, also. I've got some of the necessary data and mungable code handily sitting on a machine that I am ''unhandily'' not going to next use until at least the weekend, and reimplimenting it on this tablet would mean starting from first principles again/testing/etc... ;) [[Special:Contributions/172.70.163.120|172.70.163.120]] 09:23, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Check out the Wikipedia article &amp;quot;Azimuthal equidistant projection&amp;quot; and scroll to &amp;quot;Sample azimuthal equidistant projection maps&amp;quot;. There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the &amp;quot;great sea&amp;quot; of Randall's map, using a similar projection.

: Yay! A task for a geography teacher (i.e. me, and I'm a big fan of Randall's work with maps), and I just happen to have the right bookmarks for this kind of thing in my browser. So here's a little toy to play around with: [https://www.worldmapgenerator.com/en/wizard/step/centering/?config=eyJpZCI6IkNVU1RPTV9XSVpBUkQiLCJsYXllcklkcyI6WyJDTElQX1BBVEgiLCJCQUNLR1JPVU5EIiwiU1BIRVJFIiwiR1JBVElDVUxFUyIsIkxBTkQiLCJPQ0VBTiJdLCJwcm9qZWN0aW9uSWQiOiJBWklNVVRIQUxfRVFVSURJU1RBTlQiLCJyZW5kZXJpbmdBZGFwdGVySWQiOiJDQU5WQVMiLCJtYXBUaGVtZUlkIjoiREVGQVVMVCIsImNlbnRlciI6WzAsMF0sInJvdGF0aW9uIjpbLTgxLDQwLDBdLCJ6b29tIjowLjksIndpemFyZFN0ZXBQcm9ncmVzc0lkeCI6MywidmVyc2lvbiI6IjEuMC4wIn0%3D] I hope my settings got preserved in the link as they should, else whoever added all those letters and numbers clearly has something to answer for! If the link works as it should it'll show you what a map of the whole wide world would look like in an Azimuthal Equidistant Projection with Kansas on the exterior. That is, I first used this Antipodes Map [https://www.antipodesmap.com] to locate the point opposite to Lebanon, Kansas at 39°48'35&amp;quot;S, 81°26'39.8&amp;quot;E , which is quite literally in the middle of the Indian Ocean, near the islands of Saint Paul and Nouvelle Amsterdam (which, incidentally, belong to France and are mainly known for being as far away from anything as you can possibly get on this planet*) and then set the centre of the worldmapgenerator.com map approximately there. It's not a very precise tool, but it'll do - it's precise enough for me to use in lessons anyway. Surprisingly, you actually get a more or less usable map for much of the world (if you're not too fussy or trying to navigate with it or anything), ''except only'' for North and Middle America. :D [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 16:04, 27 June 2024 (UTC)&lt;br /&gt;

:::: I am actually on a desktop system, I can probably go in there and remove the &amp;quot;don't do anything until the Accept is clicked&amp;quot; popover ''without clicking on the popover'', and even check out what it tries to store, or doesn't... I'm not even overly paranoid about these things, but I agree with above poster that it's bad form. ''Especially'' if it's a joke (no reason to suppose it is).&lt;br /&gt;
:::: Yeah, I'll accept Cookies if essential, but often they aren't, so it's not even a very good joke to make. Maybe they do just do everything in URL-encoded/GET data. It's my own prefered method, to make fully transparent GET data on websites I use (barring anything that needs to be POST-submitted), and if I ever use cookies it's a single own-site-only cookie for session control, not the mass of &amp;quot;Legitimate Use&amp;quot; (as if!) items.&lt;br /&gt;
:::: Have you ever gone and looked in the list? (Assuming the &amp;quot;Do you accept cookies&amp;quot; doesn't do a &amp;quot;Yes, accept all&amp;quot;/&amp;quot;No, reject all (inessential)&amp;quot; and gives you the 'option' to painstakingly turn off half a dozen &amp;quot;default cookie sets&amp;quot;.) It's frightening how many 'interested parties' are potentially getting info (dozens to hundreds, at a time). And, realistically, I'm not sure I even believe that by selecting 'off' on that kind of dialogue that I'm actually not being Cookified just as much as if I accidentally clicked on the prominent &amp;quot;Accept All&amp;quot;.&lt;br /&gt;

Me being a geomatician and having a couple of friends who are map projection nerds, we had a short discussion (https://mastodon.social/@EvenRouault/112688667438256248) and I ended up implementing a web map version of a Oblique Stereographic map in the style of this: https://ivan.sanchezortega.es/2024-06-exterior-kansas/ .  You'll notice that a Oblique Stereographic projection does create a coastline that matches the one in the comic much closer to the Azimuthal Equidistant projection (and therefore, I'll hypothesize that Randall used a compromise projection). I'd like to add an image of my map to this explanation, but I seem to lack permissions.

&lt;br /&gt;
== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use. If it's a near-side orthographic projection and, say approaching +1 radii up from the surface-tangent, then it could perhaps be 'over the horizon' in the direct projection and thus 'beyond the singularity' of the inverted-radius version.)&lt;br /&gt;
:I'd have to mess with some map data, to be sure the existing features fit either idea of projection (or find the actual one (ab)used), but this'd probably be what I'd do, straight off the bat. And then I could apply it to extraterratorial features, also. I've got some of the necessary data and mungable code handily sitting on a machine that I am ''unhandily'' not going to next use until at least the weekend, and reimplimenting it on this tablet would mean starting from first principles again/testing/etc... ;) [[Special:Contributions/172.70.163.120|172.70.163.120]] 09:23, 27 June 2024 (UTC)&lt;br /&gt;

There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the &amp;quot;great sea&amp;quot; of Randall's map, using a similar projection.

: Yay! A task for a geography teacher (i.e. me, and I'm a big fan of Randall's work with maps), and I just happen to have the right bookmarks for this kind of thing in my browser. So here's a little toy to play around with: [https://www.worldmapgenerator.com/en/wizard/step/centering/?config=eyJpZCI6IkNVU1RPTV9XSVpBUkQiLCJsYXllcklkcyI6WyJDTElQX1BBVEgiLCJCQUNLR1JPVU5EIiwiU1BIRVJFIiwiR1JBVElDVUxFUyIsIkxBTkQiLCJPQ0VBTiJdLCJwcm9qZWN0aW9uSWQiOiJBWklNVVRIQUxfRVFVSURJU1RBTlQiLCJyZW5kZXJpbmdBZGFwdGVySWQiOiJDQU5WQVMiLCJtYXBUaGVtZUlkIjoiREVGQVVMVCIsImNlbnRlciI6WzAsMF0sInJvdGF0aW9uIjpbLTgxLDQwLDBdLCJ6b29tIjowLjksIndpemFyZFN0ZXBQcm9ncmVzc0lkeCI6MywidmVyc2lvbiI6IjEuMC4wIn0%3D] I hope my settings got preserved in the link as they should, else whoever added all those letters and numbers clearly has something to answer for! If the link works as it should it'll show you what a map of the whole wide world would look like in an Azimuthal Equidistant Projection with Kansas on the exterior. That is, I first used this Antipodes Map [https://www.antipodesmap.com] to locate the point opposite to Lebanon, Kansas at 39°48'35&amp;quot;S, 81°26'39.8&amp;quot;E , which is quite literally in the middle of the Indian Ocean, near the islands of Saint Paul and Nouvelle Amsterdam (which, incidentally, belong to France and are mainly known for being as far away from anything as you can possibly get on this planet*) and then set the centre of the worldmapgenerator.com map approximately there. It's not a very precise tool, but it'll do - it's precise enough for me to use in lessons anyway. Surprisingly, you actually get a more or less usable map for much of the world (if you're not too fussy or trying to navigate with it or anything), ''except only'' for North and Middle America. :D [[User:PaulEberhardt|PaulEberhardt]] ([[User talk:PaulEberhardt|talk]]) 16:04, 27 June 2024 (UTC)&lt;br /&gt;

:::: I am actually on a desktop system, I can probably go in there and remove the &amp;quot;don't do anything until the Accept is clicked&amp;quot; popover ''without clicking on the popover'', and even check out what it tries to store, or doesn't... I'm not even overly paranoid about these things, but I agree with above poster that it's bad form. ''Especially'' if it's a joke (no reason to suppose it is).&lt;br /&gt;
:::: Yeah, I'll accept Cookies if essential, but often they aren't, so it's not even a very good joke to make. Maybe they do just do everything in URL-encoded/GET data. It's my own prefered method, to make fully transparent GET data on websites I use (barring anything that needs to be POST-submitted), and if I ever use cookies it's a single own-site-only cookie for session control, not the mass of &amp;quot;Legitimate Use&amp;quot; (as if!) items.&lt;br /&gt;
:::: Have you ever gone and looked in the list? (Assuming the &amp;quot;Do you accept cookies&amp;quot; doesn't do a &amp;quot;Yes, accept all&amp;quot;/&amp;quot;No, reject all (inessential)&amp;quot; and gives you the 'option' to painstakingly turn off half a dozen &amp;quot;default cookie sets&amp;quot;.) It's frightening how many 'interested parties' are potentially getting info (dozens to hundreds, at a time). And, realistically, I'm not sure I even believe that by selecting 'off' on that kind of dialogue that I'm actually not being Cookified just as much as if I accidentally clicked on the prominent &amp;quot;Accept All&amp;quot;.&lt;br /&gt;

I don't think the middle part is meant to be seen as 'water', just 'out of scope'. [[User:Jaap-Jan|Jaap-Jan]] ([[User talk:Jaap-Jan|talk]]) 07:44, 27 June 2024 (UTC)&lt;br /&gt;
:Yeah, this is similar to a map like https://suncatcherstudio.com/uploads/patterns/us-maps/pdf-png/usa-map-states-names-color-010101.png  In that map, Canada and Mexico aren't &amp;quot;rendered as water&amp;quot;, they're not rendered at all, and neither are the oceans.

== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use. If it's a near-side orthographic projection and, say approaching +1 radii up from the surface-tangent, then it could perhaps be 'over the horizon' in the direct projection and thus 'beyond the singularity' of the inverted-radius version.)&lt;br /&gt;
:I'd have to mess with some map data, to be sure the existing features fit either idea of projection (or find the actual one (ab)used), but this'd probably be what I'd do, straight off the bat. And then I could apply it to extraterratorial features, also. I've got some of the necessary data and mungable code handily sitting on a machine that I am ''unhandily'' not going to next use until at least the weekend, and reimplimenting it on this tablet would mean starting from first principles again/testing/etc... ;) [[Special:Contributions/172.70.163.120|172.70.163.120]] 09:23, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Check out the Wikipedia article &amp;quot;Azimuthal equidistant projection&amp;quot; and scroll to &amp;quot;Sample azimuthal equidistant projection maps&amp;quot;. There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the &amp;quot;great sea&amp;quot; of Randall's map, using a similar projection.

: As the center of the map corresponds to Kansas' antipode (Kerguelen in the Indian Ocean https://www.geodatos.net/en/antipodes/united-states/kansas-city), Hawaii isn't really &amp;quot;near the center&amp;quot;, but rather to the right of the center (in the direction of the &amp;quot;Pacific Ocean&amp;quot; tag). --[[Special:Contributions/162.158.86.100|162.158.86.100]] 05:58, 27 June 2024 (UTC)&lt;br /&gt;

I don't think the middle part is meant to be seen as 'water', just 'out of scope'. [[User:Jaap-Jan|Jaap-Jan]] ([[User talk:Jaap-Jan|talk]]) 07:44, 27 June 2024 (UTC)&lt;br /&gt;
:Yeah, this is similar to a map like https://suncatcherstudio.com/uploads/patterns/us-maps/pdf-png/usa-map-states-names-color-010101.png  In that map, Canada and Mexico aren't &amp;quot;rendered as water&amp;quot;, they're not rendered at all, and neither are the oceans.  I'm going to edit that. [[Special:Contributions/162.158.78.73|162.158.78.73]] 13:34, 27 June 2024 (UTC)&lt;br /&gt;
&lt;br /&gt;
== How would the rest of the world look? ==&lt;br /&gt;
&lt;br /&gt;
Currently the center is all water. If I understand correctly the rest of the world could be added, but how would it look? For example, would Europe and Asia cover a good part of the water or would they be tiny specs in the middle (almost making this a world map already)&lt;br /&gt;
:My impression (without measuring/replicating) is that this is mathematically (or whatever) a gnomonic projection (which can only show half the world, anyway, even on a sheet stretching up to infinity) radially inverted. As such quite a lot of features that aren't shown ('beyond/within' the 'coastline'/borders) couldn't be, anyway, as more than half the world away. Map-centre would be the compressed singularity of the Great Circle exactly 90° off the 'centre of Kansas' that itself now exists at infinite-radius-every-angle far off the page.&lt;br /&gt;
:Though it could just be stereographic with any negatively positioned projection origin. Instead of -1, for gnomonic, with a -2 radii origin you would get the whole surface (at infinity!) in ways that whatever you do to radially invert (probably the direct reciprocal) and otherwise scale (clearly choosing the additional 'zoom level' factor that neatly brings the Kansas border more or less into frame) to compress all offshore/over-border territories into the 'oceanic' centre. Or it could just be a useful rescale of a -2r projection ''of'' the Kansas-antipode, such that all borders of Kansas are pulled into frame.&lt;br /&gt;
:(Regarding Hawaii, if quick googling is right about Hawaii being 3,600km from Kansas(-centre?), then that puts it at various preskewed factors towards the 'hemispherical horizon' of ~10,000km or the antipodal point at ~20,000km, before then being further squashed by the particular coordinate conversion system in use.

I don't want to be disrespectful, but it seems that the current set of admins lacks the collective time or ability to upgrade Mediawiki/MySQL and install widely available anti-vandalism and anti-spam measures. But you have perhaps the most technically inclined, supportive, and motivated audience you could hope for here. Why not use the main page top banner to ask for expert Mediawiki volunteers or if that doesn't work, funds to hire such a consultant to upgrade blocking and filtering tools or a new hosting solution if needed? I believe you'd be surprised with the extent of community support you can muster, and manually chasing vandalism is becoming tiresome.

Can we please have some agreement that &amp;lt;code&amp;gt;.&amp;quot;&amp;lt;/code&amp;gt; is better than &amp;lt;code&amp;gt;&amp;quot;.&amp;lt;/code&amp;gt;? [[Special:Contributions/172.71.150.29|172.71.150.29]] 07:08, 24 August 2022 (UTC)&lt;br /&gt;
:That would depend.&lt;br /&gt;
 When asked &amp;quot;How do you deal with endquote punctuation in quoted speech?&amp;quot; he answered &amp;quot;Yes,&amp;quot; with a definite nod of his head, &amp;quot;I would always try to put the punctuation before the quote.&amp;quot;&lt;br /&gt;
:...that is how I was taught to do it, &amp;lt;mumble&amp;gt;fumphty-fumph&amp;lt;/mumble&amp;gt; years ago, and when it is clear quoted speech (with 66s, 99s) then that's probably best. Except when it might confuse, but then a rewrite (or clearly indicated paraphrase/part-quote) might be useful. You'll note I example-quote 'wrongly' in some places below, to accomodate other factors. Like an exclamation point as a feature of the holding sentence that makes no sense at all to be translated to within the quoted sentence(-fragmant).&lt;br /&gt;
 On the other hand providing &amp;quot;a set of words&amp;quot;, with no clear quotation to them, ellicits no such compunction.&lt;br /&gt;
:...it gets a bit hazy, because a partial quote of a real full sentence (or an incomplete/incompleted quote) could go either way. But I would not consider &amp;quot;a set of words,&amp;quot; to be sensible.&lt;br /&gt;
 If you give a &amp;quot;list&amp;quot;, &amp;quot;spread&amp;quot; or &amp;quot;set&amp;quot; of singular terms then no, or even compounded ones if they are ultimately the &amp;quot;be-all&amp;quot; and &amp;quot;end-all&amp;quot;.&lt;br /&gt;
:...noting that I might personally single-quote in this case (I know not why I have adopted this principle, exactly), though I've often seen such things changed by others and it may be more contested than even the terminator punctuation. I might say that the 'true' difference is whether it is a definite &amp;quot;literal&amp;quot;, insofar as meaning, or somewhat 'ad hoc',  'foreignish' or just plain constructed.&lt;br /&gt;
:But this is just my opinion. And, regardless of my preference to quote-punctuation ordering, I've seen several recent occasions where paren-punctuation ordering was totally off (IMO). Either &amp;quot;...at the end of a sentence (an aside.)&amp;quot;, which should have been &amp;quot;... (an aside).&amp;quot; instead, or &amp;quot;(As a whole aside of its own).&amp;quot; for which it ''must'' surely be &amp;quot;(As ... of its own.)&amp;quot;&lt;br /&gt;
:Now, obviously too much ()ing is awkward, especially if nested, but I prefer the clearer in/out indication than other methods — like the mdash — which seem to be the favoured method by some editors — and, even more confusingly, often without spacing both sides. (Like &amp;quot;...by some editors—and, even more confusingly...&amp;quot;! Looks more like a hyphen, despite &amp;quot;—” and &amp;quot;–”-users changing hyphens-used-as-dashes to one or other of the dashes to try to differentiate them.)&lt;br /&gt;
:Ultimately, though, the people here will have learnt (or redeveloped) their own typographical standards over a wide range of educational eras (or under teachers/mentors whose own learnt-preferences might themselves be several decades passed into history) and with additional localisation/localization complications as well. I tend to agree with you (with caveats as mentioned) but it won't be universally acceptable. [[Special:Contributions/172.70.85.13|172.70.85.13]] 21:34, 24 August 2022 (UTC)&lt;br /&gt;

Bearing in mind the idiotic vandal(s) we have had before, and always ended up dealing with through sheer force of the more righteous and honest userbase, I think that drastic actions aren't necessary.

== Hey ==&lt;br /&gt;
&lt;br /&gt;
I cleaned everything up. You should probably restore the newest 3 topics.&lt;br /&gt;
&lt;br /&gt;
:It could definitely do with a cleanup (not the only page like this!), but in a positive and considered manner, not just wiping and expecting unwarrented deletions to be restored after your removal. Archival sub-pages (restricted/fully-protected) should be involved, perhaps, for reference/history (on top of the History view itself).&lt;br /&gt;
:Not just wiping by an unisigned contributor, as you did. I'm a hairbreadth from just reverting it all back again, on principle, and maybe someone else will do that anyway.&lt;br /&gt;
:But defering to known named users (esp. the admins) and their decision on how to procede. (Please do delete this contribution if you see fit to do any restoration and make my opinions moot.) [[Special:Contributions/172.68.138.79|172.68.138.79]] 20:26, 23 October 2022 (UTC)&lt;br /&gt;
::I agree that it needed cleanup, and also agree that wiping everything was not the best way to go about doing it. I've moved most of the deleted content to the &amp;quot;talk&amp;quot;/archive page, and put back some discussions.

== Complaint transcluded from [[user:ArthurGreenham]] ==&lt;br /&gt;
:(Ok, so, the above transclusion is subject to change at any time, as proven by While False going in there and 'wikilinking' everything since I first saw the transclusion inserted here, so perhaps a little less ephemeral explanation is needed..?)&lt;br /&gt;
:Point the first: I have no issues with While False, in general. Seems to be a good editor in general. As I recall, did a lot to counter that particularly recurring bad-faith editor who the current expanded admin set will recall. And regular editing from you, mate..? As good as anyone else, I would say. No bad-faith detected in you at all.&lt;br /&gt;
:Point the second: You do seem to be a bit too gung-ho with new pages, and similar experiments with markup. Just because you can, it seems. If those with the power to remove pages choose not to, then I'm not complaining, but I still think it's a bit... self-indulgant. Not that a mere IP like me can rightfully complain.&lt;br /&gt;
:Point the third: Clearly, among the mass of newly registered users (who never then contribute) there is a large cohort generated by some external script(s) for the intention of SEO/propogation of linky-links. I suspect that they're set to do this on any wiki that they can create accounts upon, mindlessly and with the initiating 'intelligence' not bothered how well they do it (economies of scale, as per spamming/etc) because some will do it and fulfil whatever purpose.&lt;br /&gt;
:Point the fourth: But, back a long time ago, our chief admin here (and his then current peers/etc?) set it up so that new users just did not so easily create brand new pages. Without overly restricting the spamming of user-registration (or, more importantly, legitimately interested actual contributors) it stymied the scripts that were creating users that then could not create (and write their spam upon) the pages they were programmed to create.&lt;br /&gt;
:Point the fifth: But if someone who is an autoconfirmed user looks at the accounts created (I'm guessing here, so corrects me if I'm wrong) and decides to make the pages that new and heretofor uncontriutive users ''cannot'' create for themselves, there are times (at least two, that I know of) that the mindless spam-script has not given up and moved on from putting their random link-spam upon RandomNewname's user page. And as RandomNewname ''has'' a page, it does its preprogrammed stuff.&lt;br /&gt;
:...and the world does not stop turning, if that happens. But it does just marginally increase the benefits vs costs of the spam-engine technique (which are probably already breaking even and more, across all speculative spam-destinationa) and I'd suggest we shouldn't be helping with that any more than we already have to.&lt;br /&gt;
:Maybe theusaf could add to their own bot some sort of detection of a suspicious level of linkspamming upon a user's own pages (to neuter these that leak through, like the ones that it deals with in other circumstances), but that'd be difficult without having false-positives upon genuine new users with (once they can) a genuine reason to populate their userspace with various external links.&lt;br /&gt;
:Instead, perhaps hold back upon feeding the spambots the fresh ground that they seem to like to make use of. Perhaps a page for &amp;quot;please create my userspace!&amp;quot; if we want genuine users (or at least ones that can find and read instructions) to get a userspace more quickly than the normal limits apply, so any established (named) editor can give them their Welcome-templated editspace.&lt;br /&gt;
:We can't so easily protect against conscious bad-faith editors (we will just have to deal with them, as we have done), but we seem to have sufficient anti-bot defences. If misguided editing doesn't open up cracks in the walls.&lt;br /&gt;
:...Ok, that looks like a rant, but was just intended to cover (much of) the issue as I saw it in a way that explained my accumulated thinking on the matter. And I clearly think too much. This is not a diatribe against anybody (except the spambot originators), just a plea for action (or, rather, inaction) in a key way. And perhaps some moderator-level cleanup, so that the above transclusion is now effectively red-linked (then delete/archive this horribly overblown entry). Leaving it up to you lot. Have fun!

==2696: Accuracy and precision==&lt;br /&gt;
This is my first edit/post here. Could someone please include the Wikipedia link to &amp;quot;Accuracy and precision&amp;quot; [https://en.wikipedia.org/wiki/Accuracy_and_precision], which is a separate article from 'accuracy' and 'precision'? Thanks! unsigned ip|172.71.98.97|16:04, 9 November 2022}}&lt;br /&gt;
:If someone else hasn't done already, it's trivial enough to do yourself in a similar way to how you edited here, in any one of a number of ways.&lt;br /&gt;
:*By bare URL (shows the URL, like https://en.wikipedia.org/wiki/Accuracy_and_precision but not really suitable here)&lt;br /&gt;
:*As you did it above, with [] around the URL, giving a 'reference'-like link. Occaisionally useful, but a little impersonal in most cases.&lt;br /&gt;
:**Or use URL and alternate text in the []s (space-separated) &amp;lt;nowiki&amp;gt;[https://en.wikipedia.org/wiki/Accuracy_and_precision like this]&amp;lt;/nowiki&amp;gt;, which looks [https://en.wikipedia.org/wiki/Accuracy_and_precision like this] and is most useful for non-wiki links that you can describe well, or associate into the flow of text.&lt;br /&gt;
:*An internal wiki link is defined like &amp;lt;nowiki&amp;gt;[[2696: Precision vs Accuracy]]&amp;lt;/nowiki&amp;gt; and renders as [[2696: Precision vs Accuracy]], which is common site practice (you could alse link to [[2696]] or [[Precision vs Accuracy]], in most cases, which are redirects) but doesn't help in the above link's case.&lt;br /&gt;
:**If you wanted to internally link with [[2696: Precision vs Accuracy|other text]] then using &amp;lt;nowiki&amp;gt;[[2696: Accuracy and precision|other text]]&amp;lt;/nowiki&amp;gt; is the way to do it (use the pipe delimiter).&lt;br /&gt;
:*When it comes to wikipedia links, though, we have a nice template for it. By using &amp;lt;nowiki&amp;gt;Accuracy and precision}}&amp;lt;/nowiki&amp;gt; (or with the underscored version of the title, if you wish) you get a link to {Accuracy and precision}}, with the nicer aesthetic. '''Probably what you wanted.''' You can lowercase the &amp;quot;A&amp;quot; and it will still link (usually... always good to check) and linking to something like a w|noun}} can generally be written as &amp;lt;nowiki&amp;gt;|noun}}s&amp;lt;/nowiki&amp;gt; should you wish the flow of text to seemlessly render the link as being for multiple noun}}s, thanks to a little more background trickery.&lt;br /&gt;
:**If you want to use more &amp;lt;nowiki&amp;gt;Accuracy_and_precision|replaced text}}&amp;lt;/nowiki&amp;gt; then you get aAccuracy_and_precision|replaced text}} rendering. '''Another possibility for what you'd wish to use, here.'''&lt;br /&gt;
:**Similar templates exist for linking the likes of emplate|wiktionary}} and evenemplate|tvtropes}}, should you need them.&lt;br /&gt;
:**...noting that the latter needs the NoSpacesVersion of the title and because tropes|TVTropesWillRuinYourLife|TV Tropes Will Ruin Your Life}}, it has a slightly more forboding format, even though it isn't really ''that'' much worse than [[214: The Problem with Wikipedia]]. ;)&lt;br /&gt;
:In case that's of any use to you, or anybody else. There are a few more tips and tricks, but this covers a lot of the usage-cases.&lt;br /&gt;
:Also, in discussion pages and ones like this, it's useful to sign your contribution with the four tildes. But it's easy to forget and there are templates to mark unsigned contribution. As I did above. Don't worry about it. It just lets you datestamp and demarkate elements of conversation in a useful manner. As a first edit, you can be forgiven, but just so you know for future!

As of the 22nd, the users ChuddyCobson and CobsonTheGemson are responsible for a large amount of attacks and image vandalism, most of them NSFW (inappropiate and/or gore). Can something be done about them? [[User:Gyozaplanet|Gyozaplanet]]&lt;br /&gt;
&lt;br /&gt;
I noticed the image for 1460 has been vandalized.  But, in looking at the history it shows an old vandalism that was fixed.  But following the link in the alleged fix gets the vandalized image.  I'm out of my depth for fixing this, but couldn't find a better place to report it.  It's getting too late and I'm far too tired to do more...  (As an aside to what I came here for, are the above two things vandalism here?  That's a rathole I'm not continuing down.) [[User:MAP|MAP]] ([[User talk:MAP|talk]]) 09:37, 22 December 2022 (UTC)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
A few hours ago I decided to visit this wiki, and got quite the surprise on the front page, in that it was heavily vandalized. Decided to make an account after looking at recent changes and saw how much there was.&lt;br /&gt;
&lt;br /&gt;
The accounts involved seem to be these;&lt;br /&gt;
* CobsonTheGemson&lt;br /&gt;
* ChuddyCobson&lt;br /&gt;
* Cobson&lt;br /&gt;
* Stinkycobbypoopoo&lt;br /&gt;
* Chud&lt;br /&gt;
* GotTheJakkyDoe&lt;br /&gt;
&lt;br /&gt;
Kinda confused since they don't seem to be bots but I assume they're using a script or something to automate their vandalism. As far as I know, A few other people and I reverted more or less everything those accounts have done but it's possible some stuff fell through the cracks.&lt;br /&gt;
&lt;br /&gt;
Also some of the gifs I reverted (most notably the gif for 381) seem to still have the same image so I'm hoping that's just a cache thing that'll sort itself out in time.&lt;br /&gt;
&lt;br /&gt;

== Current troll(s) ==&lt;br /&gt;
There's trolls posting extremely obscene stuff on the homepage, and frankly I'm appalled. The Admins need to take several steps to lock down the main page so that it's not possible for readers to view such obscene content (for example, why are arbitrary images that don't come from xkcd.com allowed???) Why are random users allowed to post arbitrary images that are not filtered/scanned in any way? ([[User:bkayes|bkayes]])&lt;br /&gt;
: It's been like this forever.

::: I find it unfortunate that &amp;quot;rarity&amp;quot; is any sort of excuse for allowing this to happen. XKCD is a fantastic source of quality STEM entertainment, and thus is a great resource to get younger audiences interested in such fields through humor. Many high school age and younger people regularly view xkcd content. However, some of the comics are quite obscure or contain a lot of depth, which is why explainxkcd has been such a great resource for everyone to learn things that are outside of their depth (including younger audiences). The knowledge that someone can open explainxkcd and have the slightest chance that they see extreme gore/porn is absolutely absurd and unacceptable for a wiki that is serving solely family friendly science content. I can no longer recommend explainxkcd to people I know (and especially not younger people) because of the lack of modern anti-trolling tooling, and that really sucks. I understand the issues surrounding locking down the text explanations, but the images should be a trivially solvable problem. Compare a checksum between the image found at *.xkcd.com and the image uploaded and reject an image that doesn't match, or better yet *use the official xkcd RSS feed* (https://xkcd.com/rss.xml) to download the images directly, and don't allow any user edits of the images. Then you can deal with vandalization of the text some other time, locking down the images is really the highest priority here I think.

Actually, looking at [https://www.explainxkcd.com/wiki/index.php?title=Special:Log/newusers&amp;amp;limit=500&amp;amp;type=newusers&amp;amp;user= Special:Log/newusers] is pretty ominous. Nearly all of the last 500 (within the past 4 days), and also the next few thousand, are suspicious. The CAPTCHA probably needs to be replaced with something more difficult that is perhaps not as trivially automatable? And all those users blocked? Not sure. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 22:05, 4 July 2023 (UTC)&lt;br /&gt;
:As a regular checker of such things, I know for a fact that you get hundreds of 'suspicious' accounts created every day, and most of them 'go nowhere'. The account creation speedblocks may not be very good. Or, possibly, tens of thousands of accounts are ''tried'' to be created, with 'just' a small percentage of them getting past the CAPTCHA/etc to get noticed by us - the actual top-level site admins will have access to the 'failed to register fully' logs. ''But'', the actual page vandalism is very rarely any of these 'mechanised spam accounts'. I presume because the CAPTCHAs throttle down the 'lucky' accounts' abilities to do anything they were programmed to do ''once'' registered. And, no, the accounts aren't blocked (i.e. disabled accounts, except on very ''rare'' occasions when an Admin gets annoyed with a conspicuously used spam-login), if the actual Block Log is to be believed, but so many get created and ''never'' used so it looks like the &amp;quot;new user early posts&amp;quot; precautionary checks do a very good job.&lt;br /&gt;
:We're also getting that idiot (I presume the same idiot as we've had for a year or two now) who manually creates accounts, such as you have been dealing with (and me, and others) over the last 24 hours or so. As a stupid human rather than a 'smart' bot, the CAPTCHA is no block to him/her/them. And the occasional IP gets used in that way, too (and I mostly successfully revert vandalism as only an IP; usefully, I hope) which might just be lazy vandalism, on top of the baseline stupidity. But the precautions against them are different. As with the 'Eric's (&amp;quot;Hi, I see your website needs improving - Eric&amp;quot;-types of message), which also seem to be handled by the community (and/or our automated blocking/reverting).&lt;br /&gt;
:I don't see increasing the severity of the CAPTCHA to be a solution to much, honestly. Not from my perspective, certainly, though I know there's no reason to take my own unattributable word on that.&lt;br /&gt;
:Instead, we should keep on keeping on. The community handles these things as they need to be. The admins know the 'hidden fight' going on in the background, but won't (and shouldn't) reveal too much about the extent of the first-line defences against bad faith 'automated' edits and the rest.

== Vandalism on page 2805 ==&lt;br /&gt;
&lt;br /&gt;
The latest comic page (2805) is currently being vandalized. Can an admin please look into it?&lt;br /&gt;
&lt;br /&gt;
== Problem with new accounts and IPs ==&lt;br /&gt;
&lt;br /&gt;
So I'm sure many of you are well aware of the vandalism happening recently. But what concerns me the most is that all the edits were done by many, many different IPs, meaning that we can't just block one, and this site could get overrun by systematic IP vandalism. Also, the new accounts being created seem very suspicious. For such a small community, there's no way that there can be around 100 new users each day. The actual usernames of the users seem to follow a very repetitive pattern (generic first name + generic last name + random number). [[Special:Contributions/172.70.42.209|172.70.42.209]] 18:44, 24 July 2023 (UTC)&lt;br /&gt;
:As a fellow IP (and not a vandal myself, at least by intent) I find that the advantages of being able to leap in and correct (often 'named') damage outweigh the relatively small amount of IP-led vandalism. And the details of how the IPs represent the (limited, but geographically distributed) Cloudflare gateways has been noted before a number of times, together with what can be done about/with them.&lt;br /&gt;
:About the new accounts... Look back for ''years'', and you'll see the same (or similar) patterns. Almost all the truly rogue (presumably automated generation/'registering') then do nothing else as the site blocks the (still automated) attempts to do something with them.&lt;br /&gt;
:The worst danger this site is threatened by is the actual manually-posting individuals who (IPed or named) can do what they like so long as (like us legitimate editors) they are prepared to be sat at the keyboard and spend/waste the time in navigating the initial CAPTCHAs/etc to set down their changes. And there's not much more anybody can do about them without ruining everyone else's experience to a similar degree. Perhaps there's some adjustments possible, but none seem necesary to address the account-spam and other precautions are intercepting/reverting the lion's share of the edit-spam (with or without accounts).&lt;br /&gt;
:Not up to me, but I trust in those who it is up to. To continue with what is happening right now or to respond in new ways to anything that needs a new approach. Not saying that I don't have ideas of my own, for if I were able to intervene, but I doubt it'd be useful to voice them.

== Large amounts of vandalism involving disturbing imagery. ==&lt;br /&gt;
&lt;br /&gt;
Page 2805 has a huge vandalism problem. Vandals (it seems to be the same few people over and over, or maybe one person with multiple addresses) keep covering the page with weird, disturbing photos and way-too-bright colors.&lt;br /&gt;
A few people have been valiantly fighting back but that doesn't mean this isn't a problem.&lt;br /&gt;
I would like to please request that the page be locked to prevent further vandalism, and that you please ban all the people that have vandalized it in this way before (and/or take some other action to prevent future vandals) . Thank you very much! [[User:(insert name here)|(insert name here)]] ([[User talk:(insert name here)|talk]]) 01:20, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
There also seems to be a parser problem where instead of vandals replacing the page source, the vandalism is appended to the end, even though it isn't in the source. [[Special:Contributions/172.71.174.230|172.71.174.230]] 03:39, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
The optimal way to go would be to add bots that automatically replace questionable content like divs and detect image/word spam (like the one in Wikipedia). They would always be on so the vandals would get overwhelmed. Similarly I'd suggest monitoring the constant stream of IP addresses and created accounts. Most editors are IP addresses though, so you might want to watch out for that. Does ExplainXKCD have semiprotection capabilities? You would definitely want to do that, especially the important articles like [[xkcd]], [[Randall Munroe]], [[Cueball]], [[1:_Barrel_-_Part_1]], and ALL of the templates (the vandals were targeting those the most).

&lt;br /&gt;
: I agree that the important pages (primary pages, plus all templates) need to be protected somehow so that this can't happen again. It's nice to have a low threshold to editing; it's nicer having a resource that can be depended on and doesn't require random volunteers jumping in to save. (Let's be honest; the images the vandal posted could have been much, much worse.) -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 12:28, 25 July 2023 (UTC)&lt;br /&gt;

== Becoming an admin? ==&lt;br /&gt;
&lt;br /&gt;
Hi. I've been contributing occasionally for eight years now, and I think I've been helpful. But, almost half of the edits were last night in that wave of vandalism. It was very frustrating knowing that I had the same tools as the (14-year-old?) vandal, and the only end-point to the fun would be one of us throwing in the towel, and it was probably going to me (bedtime).&lt;br /&gt;
&lt;br /&gt;
I don't have the time and/or commitment to do regular moderation work, but I (think I) am a reasonable person, who deals with conflicts rationally and could help out in a pinch. Is there a chance I could be given some more powers to help out if (when) such a crap-storm happens again? Thanks for your consideration... -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 11:14, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
:I saw your efforts, early on in my own day, definitely looked to be amongst the helpful editors. I later picked up several cases (might have missed a couple, that others IDed before me) after I got online, and undid that latest form of vandalism in both templates (agree with above, they probably should be semi-protected) and pages. A simple Undo even at my level was sufficient to revert practically everything. What might have been handy was one of the top-moderators being around to use the mass-revert tools to streamline that, and keep on top of the account (or account''s'', as the problematic one would definitely open new accounts - we've seen them do this before) deserving to be blocked and banished. Unfortunately, the freedom of a wiki (which I value) doesn't really work well with over-administration. But that's a discussion to be had by those already at the top levels. I don't envy them.

I'm almost glad I'm not the only one with this issue with the user and talk page. I was kind of asking myself what I've done not to be permitted a user page, you know. I remember trying to create one once upon a time, which included a link to my own webcomic. It didn't save for some reason and after that I wasn't permitted to create a user page.

:With a dozen edits (up to and including the above), and a decent amount of time, I'd have expected you to be over the nominal threshold to give you the right to create your pages.&lt;br /&gt;
:(I'm not entirely sure what the criteria are, off the top of my head, though I know it's been discussed elsewhere. And if I were configuring it, I'd not put too much weight on &amp;quot;the number of edits&amp;quot; or &amp;quot;the net amount of added bytes&amp;quot;/whatever, as it could encourage pointless editing-for-the-sake-of-editing, rather than relying upon 'time served' to weed out those who are in a rush to create havoc... but there's arguments to make it a combination of criteria. And it's not up to me, anyway..!)&lt;br /&gt;
:Firstly, have you tried again recently, like right now? If you have, and it still won't 'take', or even let you get that far, then there's plenty of longer-term/higher-intensity users that ''might'' look kindly upon your participation and answer your plight. But do try again.&lt;br /&gt;

== XKCD Browser ==&lt;br /&gt;
&lt;br /&gt;
I made a [https://github.com/kristianbenoit/XKCD XKCD browser] in python with pygame and think it could be useful to others. The idea was to popup a comic the morning after it was published from a crontab. There could be a hotkey to point to todays discussion on explainxkcd. I wonder where/how would be the place to advertise it ? [[User:Kbenoit|Kbenoit]] ([[User talk:Kbenoit|talk]]) 15:36-40, 20 February 2024 (UTC)&lt;br /&gt;
:Here's a good start. Perhaps on the comic discussions for similar things ([https://uni.xkcd.com/ unixkcd], etc). As and when you get a User page here then you can perhaps expound on it there (assuning you aren't leaving the explanation to the github webspace.

Maybe indeed I should have pointed at [[UniXKCD]], or [[Talk:UniXKCD]], but I wasn't sure that was even the best place on here. Look around the [[:Category:Interactive comics]], and/or ones featuring browsers lrominently, maybe.&lt;br /&gt;
::I repeat that you (Kristian, with our help at bumping the contribution here) have already now made it known/knowable, at least to those who browse this site widely, but once you get a Userspace page you can perhaps do a little bit more in your own free space and also push people there through subtle pointers or signature-links in further on-context contributions. This isn't really a place for random advertising, but definitely contextual links to offsite xkcd 'fandom' is not something I'd personally have issues with (certainly compared to some other things that might get snuck on here).

== Vandalism-related Ban Request ==&lt;br /&gt;
&lt;br /&gt;
Hey, if any of the admins see this, can you please ban Jupitale? They’ve made 11 vandalism-related edits, within the time frame of about 21 hours. Even though they haven’t ben active since February 28, I feel like it’s better to err on the more cautious side. Thanks! ^_^ [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 01:09, 5 March 2024 (UTC)&lt;br /&gt;
:It'd be even more cautious not to [https://www.explainxkcd.com/wiki/index.php?title=User:Ash123&amp;amp;action=history create userpages] for a user that [https://www.explainxkcd.com/wiki/index.php?title=Talk:1211:_Birds_and_Dinosaurs&amp;amp;diff=prev&amp;amp;oldid=336532 was only here to spam us].. (Note to admins: add Ash123 to that todo list, if we're calling them out, and I know I've reverted some other single-spamming usernames recently.) But you just know that a ban for anyone like 'Jupitale' (as much as they'd deserve it) is going to be of no actual consequence to them.&lt;br /&gt;
:And hold off on all those other userpages, 42. It's not your job, and you might not be right about the usefulness of the ones you're (seemingly randomly) creating. Without even being asked.  [[Special:Contributions/172.69.194.217|172.69.194.217]] 01:55, 5 March 2024 (UTC)&lt;br /&gt;

We need to know a few more details to the idea.&lt;br /&gt;
:And I presume you meant &amp;quot;a countdown in a suitably xkcx-ish manner, as there have been countdowns for books/etc but not a consistent approach, just some wide ranging but apt creative teasers [[Special:Contributions/172.69.194.225|172.69.194.225]] 11:32, 25 March 2024 (UTC)&lt;br /&gt;

== Unblock request ==&lt;br /&gt;
&lt;br /&gt;
Hello! I tried to sign up for an account a couple years ago, but I happened to sign up during a major vandal attack, and an admin blocked me based on a mistaken accusation of vandalism and sockpuppetry. I had used the account [[User:Danny E. Corchado]], then I used [[User:Danny Corchado]] to attempt to appeal my block shortly afterwards; both accounts are now blocked. I no longer have the password to the former, but I can log in to the latter account. Can someone please unblock [[User:Danny Corchado]]? If someone creates [[User talk:Danny Corchado]], I should be able to edit that page to prove I do control the account.

::Really? You actually think this could work like that? Both(/'both'?) of you? I wondered why you (42) randomly created that user's page from (from 'your' perspective) the mists of time. Which doesn't help unblock anyone, there's not even any logic in that request. (Once unblocked, whoever controls the account can prove that ''they control the account''. But where does that lead anyone?)&lt;br /&gt;
::And why would you associate ''in any way'' with an account 'of no account' that was linked with vandalism? You can only be judged by your actions, as you can choose any name (within reason) that you want. &amp;quot;Mr Corchado&amp;quot; still has uncounted options left if he absolutely must post, in all good faith, as 'Dan Corchado' or similar.

Hi. When I logged in today, I saw that the Main Page was deleted just 2 minutes before by Mark Hurd.

== &amp;quot;Interesting&amp;quot; Account Creations ==&lt;br /&gt;
&lt;br /&gt;
Hi. So I was looking at the user creation log, and I noticed a suspicious number of accounts-at least 90% of them-are being created using a &amp;lt;Semi-generic first name&amp;gt; &amp;lt;semi-generic last name&amp;gt; &amp;lt;usally two or three numbers&amp;gt;. This would be kinda weird in the first place, however, almost none of the accounts are active. That and the fact that these accounts are being created no less than 10 minutes from each other made me think somethings a little weird. Maybe I'm just dumb. Just wanted to bring it to your attention in case this wasn't a normal thing.[[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 17:17, 15 April 2024 (UTC)&lt;br /&gt;
I looked a bit further, the exact same thing happened two months ago as well, but the names were random letters instead [[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 17:34, 15 April 2024 (UTC)&lt;br /&gt;
:It's been happening (in various forms) for years. Maybe a decade, if not more. For as long as I've been paying attention, certainly, which might well be that long.&lt;br /&gt;
:Without access to the whole admin logs, it seems to reflect the intention of 'bots to spam, spam and spam again, automatically, creating accounts they will use to do so but then hitting the actually rather effective anti-bot defenses, so they do absolutely nothing (well, maybe they're lucky every now and again, but practically insignificant successes, and IP-only spams seem to dominate, at maybe twice a week for who-knows-how-many wctual attempts).&lt;br /&gt;
:Amongst the current bunch randomly created names, I see a few that are clearly created around the word &amp;quot;Ingredients&amp;quot; (rather than a feedstock to create 'FirstnameLastname', which has long been the main default). I take it that each meta-pattern we see as indicative of a different bot-farmer's efforts, so this might have been started up for a particular spam-theme. Which maybe we'll get an idea of if it gets lucky. Though I'm in no hurry to find out such details. [[Special:Contributions/172.71.242.13|172.71.242.13]] 12:39, 16 April 2024 (UTC)&lt;br /&gt;

I don't want to be disrespectful, but it seems that the current set of admins lacks the collective time or ability to upgrade Mediawiki/MySQL and install widely available anti-vandalism and anti-spam measures. But you have perhaps the most technically inclined, supportive, and motivated audience you could hope for here. Why not use the main page top banner to ask for expert Mediawiki volunteers or if that doesn't work, funds to hire such a consultant to upgrade blocking and filtering tools or a new hosting solution if needed?

== Basic punctuation standards ==&lt;br /&gt;
Can we please have some agreement that &amp;lt;code&amp;gt;.&amp;quot;&amp;lt;/code&amp;gt; is better than &amp;lt;code&amp;gt;&amp;quot;.&amp;lt;/code&amp;gt;? [[Special:Contributions/172.71.150.29|172.71.150.29]] 07:08, 24 August 2022 (UTC)&lt;br /&gt;
:That would depend.&lt;br /&gt;
 When asked &amp;quot;How do you deal with endquote punctuation in quoted speech?&amp;quot; he answered &amp;quot;Yes,&amp;quot; with a definite nod of his head, &amp;quot;I would always try to put the punctuation before the quote.&amp;quot;&lt;br /&gt;
:...that is how I was taught to do it, &amp;lt;mumble&amp;gt;fumphty-fumph&amp;lt;/mumble&amp;gt; years ago, and when it is clear quoted speech (with 66s, 99s) then that's probably best. Except when it might confuse, but then a rewrite (or clearly indicated paraphrase/part-quote) might be useful. You'll note I example-quote 'wrongly' in some places below, to accomodate other factors. Like an exclamation point as a feature of the holding sentence that makes no sense at all to be translated to within the quoted sentence(-fragmant).&lt;br /&gt;
 On the other hand providing &amp;quot;a set of words&amp;quot;, with no clear quotation to them, ellicits no such compunction.&lt;br /&gt;
:...it gets a bit hazy, because a partial quote of a real full sentence (or an incomplete/incompleted quote) could go either way. But I would not consider &amp;quot;a set of words,&amp;quot; to be sensible.&lt;br /&gt;
 If you give a &amp;quot;list&amp;quot;, &amp;quot;spread&amp;quot; or &amp;quot;set&amp;quot; of singular terms then no, or even compounded ones if they are ultimately the &amp;quot;be-all&amp;quot; and &amp;quot;end-all&amp;quot;.&lt;br /&gt;
:...noting that I might personally single-quote in this case (I know not why I have adopted this principle, exactly), though I've often seen such things changed by others and it may be more contested than even the terminator punctuation. I might say that the 'true' difference is whether it is a definite &amp;quot;literal&amp;quot;, insofar as meaning, or somewhat 'ad hoc',  'foreignish' or just plain constructed.&lt;br /&gt;
:But this is just my opinion. And, regardless of my preference to quote-punctuation ordering, I've seen several recent occasions where paren-punctuation ordering was totally off (IMO). Either &amp;quot;...at the end of a sentence (an aside.)&amp;quot;, which should have been &amp;quot;... (an aside).&amp;quot; instead, or &amp;quot;(As a whole aside of its own).&amp;quot; for which it ''must'' surely be &amp;quot;(As ... of its own.)&amp;quot;&lt;br /&gt;
:Now, obviously too much ()ing is awkward, especially if nested, but I prefer the clearer in/out indication than other methods — like the mdash — which seem to be the favoured method by some editors — and, even more confusingly, often without spacing both sides. (Like &amp;quot;...by some editors—and, even more confusingly...&amp;quot;!

: As the IP who subsequently reverted those back out of existence (wasn't sure you'd seen it, but was clear to me it wasn't a useful/good-faith commentary, and now I find that you had and had certainly ignored it in-situ) I have mixed opinions. I could not have done my (good faith) edit if somehow restricted, in a way someone had previously gotten around. Bearing in mind the idiotic vandal(s) we have had before, and always ended up dealing with through sheer force of the more righteous and honest userbase, I think that drastic actions aren't necessary. But I can think of a few minor tweaks that maybe the current adminship can still hold in reserve and occasionally employ, without preventing the likes of me (long time contributor, but not yet decided to make it 'official') occasionally poking registered users' Talk pages with genuine queries or comments under most circumstances that may actually warrant it.&lt;br /&gt;
: That said, we have indeed had a spate of vandalism, recently, which I'm inclined to believe is 'our old friend' who probably decided he(?) was bored again. A few novel tricks (nonsense 'cat on keyboard' edits with no clear pattern to the nonsense or what it replaces) but in association with some of the old ones (global word replacements throughout an article). Quickly recorrected in all cases, SFAICT, so not a big problem.&lt;br /&gt;

:Not just wiping by an unisigned contributor, as you did. I'm a hairbreadth from just reverting it all back again, on principle, and maybe someone else will do that anyway.&lt;br /&gt;

== Complaint transcluded from [[user:ArthurGreenham]] ==&lt;br /&gt;
:(Ok, so, the above transclusion is subject to change at any time, as proven by While False going in there and 'wikilinking' everything since I first saw the transclusion inserted here, so perhaps a little less ephemeral explanation is needed..?)&lt;br /&gt;
:Point the first: I have no issues with While False, in general. Seems to be a good editor in general. As I recall, did a lot to counter that particularly recurring bad-faith editor who the current expanded admin set will recall. And regular editing from you, mate..? As good as anyone else, I would say. No bad-faith detected in you at all.&lt;br /&gt;
:Point the second: You do seem to be a bit too gung-ho with new pages, and similar experiments with markup. Just because you can, it seems. If those with the power to remove pages choose not to, then I'm not complaining, but I still think it's a bit... self-indulgant. Not that a mere IP like me can rightfully complain.&lt;br /&gt;
:Point the third: Clearly, among the mass of newly registered users (who never then contribute) there is a large cohort generated by some external script(s) for the intention of SEO/propogation of linky-links. I suspect that they're set to do this on any wiki that they can create accounts upon, mindlessly and with the initiating 'intelligence' not bothered how well they do it (economies of scale, as per spamming/etc) because some will do it and fulfil whatever purpose.&lt;br /&gt;
:Point the fourth: But, back a long time ago, our chief admin here (and his then current peers/etc?) set it up so that new users just did not so easily create brand new pages. Without overly restricting the spamming of user-registration (or, more importantly, legitimately interested actual contributors) it stymied the scripts that were creating users that then could not create (and write their spam upon) the pages they were programmed to create.&lt;br /&gt;
:Point the fifth: But if someone who is an autoconfirmed user looks at the accounts created (I'm guessing here, so corrects me if I'm wrong) and decides to make the pages that new and heretofor uncontriutive users ''cannot'' create for themselves, there are times (at least two, that I know of) that the mindless spam-script has not given up and moved on from putting their random link-spam upon RandomNewname's user page. And as RandomNewname ''has'' a page, it does its preprogrammed stuff.&lt;br /&gt;
:...and the world does not stop turning, if that happens. But it does just marginally increase the benefits vs costs of the spam-engine technique (which are probably already breaking even and more, across all speculative spam-destinationa) and I'd suggest we shouldn't be helping with that any more than we already have to.&lt;br /&gt;
:Maybe theusaf could add to their own bot some sort of detection of a suspicious level of linkspamming upon a user's own pages (to neuter these that leak through, like the ones that it deals with in other circumstances), but that'd be difficult without having false-positives upon genuine new users with (once they can) a genuine reason to populate their userspace with various external links.&lt;br /&gt;
:Instead, perhaps hold back upon feeding the spambots the fresh ground that they seem to like to make use of. Perhaps a page for &amp;quot;please create my userspace!&amp;quot; if we want genuine users (or at least ones that can find and read instructions) to get a userspace more quickly than the normal limits apply, so any established (named) editor can give them their Welcome-templated editspace.&lt;br /&gt;
:We can't so easily protect against conscious bad-faith editors (we will just have to deal with them, as we have done), but we seem to have sufficient anti-bot defences. If misguided editing doesn't open up cracks in the walls.&lt;br /&gt;
:...Ok, that looks like a rant, but was just intended to cover (much of) the issue as I saw it in a way that explained my accumulated thinking on the matter. And I clearly think too much. This is not a diatribe against anybody (except the spambot originators), just a plea for action (or, rather, inaction) in a key way. And perhaps some moderator-level cleanup, so that the above transclusion is now effectively red-linked (then delete/archive this horribly overblown entry). Leaving it up to you lot. Have fun!

==2696: Accuracy and precision==&lt;br /&gt;
This is my first edit/post here. Could someone please include the Wikipedia link to &amp;quot;Accuracy and precision&amp;quot; [https://en.wikipedia.org/wiki/Accuracy_and_precision], which is a separate article from 'accuracy' and 'precision'? Thanks! unsigned ip|172.71.98.97|16:04, 9 November 2022}}&lt;br /&gt;
:If someone else hasn't done already, it's trivial enough to do yourself in a similar way to how you edited here, in any one of a number of ways.&lt;br /&gt;
:*By bare URL (shows the URL, like https://en.wikipedia.org/wiki/Accuracy_and_precision but not really suitable here)&lt;br /&gt;
:*As you did it above, with [] around the URL, giving a 'reference'-like link. Occaisionally useful, but a little impersonal in most cases.&lt;br /&gt;
:**Or use URL and alternate text in the []s (space-separated) &amp;lt;nowiki&amp;gt;[https://en.wikipedia.org/wiki/Accuracy_and_precision like this]&amp;lt;/nowiki&amp;gt;, which looks [https://en.wikipedia.org/wiki/Accuracy_and_precision like this] and is most useful for non-wiki links that you can describe well, or associate into the flow of text.&lt;br /&gt;
:*An internal wiki link is defined like &amp;lt;nowiki&amp;gt;[[2696: Precision vs Accuracy]]&amp;lt;/nowiki&amp;gt; and renders as [[2696: Precision vs Accuracy]], which is common site practice (you could alse link to [[2696]] or [[Precision vs Accuracy]], in most cases, which are redirects) but doesn't help in the above link's case.&lt;br /&gt;
:**If you wanted to internally link with [[2696: Precision vs Accuracy|other text]] then using &amp;lt;nowiki&amp;gt;[[2696: Accuracy and precision|other text]]&amp;lt;/nowiki&amp;gt; is the way to do it (use the pipe delimiter).&lt;br /&gt;
:*When it comes to wikipedia links, though, we have a nice template for it. By using &amp;lt;nowiki&amp;gt;Accuracy and precision}}&amp;lt;/nowiki&amp;gt; (or with the underscored version of the title, if you wish) you get a link to {Accuracy and precision}}, with the nicer aesthetic. '''Probably what you wanted.''' You can lowercase the &amp;quot;A&amp;quot; and it will still link (usually... always good to check) and linking to something like a w|noun}} can generally be written as &amp;lt;nowiki&amp;gt;|noun}}s&amp;lt;/nowiki&amp;gt; should you wish the flow of text to seemlessly render the link as being for multiple noun}}s, thanks to a little more background trickery.&lt;br /&gt;
:**If you want to use more &amp;lt;nowiki&amp;gt;Accuracy_and_precision|replaced text}}&amp;lt;/nowiki&amp;gt; then you get aAccuracy_and_precision|replaced text}} rendering. '''Another possibility for what you'd wish to use, here.'''&lt;br /&gt;
:**Similar templates exist for linking the likes of emplate|wiktionary}} and evenemplate|tvtropes}}, should you need them.&lt;br /&gt;
:**...noting that the latter needs the NoSpacesVersion of the title and because tropes|TVTropesWillRuinYourLife|TV Tropes Will Ruin Your Life}}, it has a slightly more forboding format, even though it isn't really ''that'' much worse than [[214: The Problem with Wikipedia]]. ;)&lt;br /&gt;
:In case that's of any use to you, or anybody else. There are a few more tips and tricks, but this covers a lot of the usage-cases.&lt;br /&gt;
:Also, in discussion pages and ones like this, it's useful to sign your contribution with the four tildes. But it's easy to forget and there are templates to mark unsigned contribution. As I did above. Don't worry about it. It just lets you datestamp and demarkate elements of conversation in a useful manner. As a first edit, you can be forgiven, but just so you know for future!

:...I must say, I never thought about that, or I might have not concentrated on the link-formatting stuff (which I hope was just as useful, in its own way).&lt;br /&gt;

As of the 22nd, the users ChuddyCobson and CobsonTheGemson are responsible for a large amount of attacks and image vandalism, most of them NSFW (inappropiate and/or gore). Can something be done about them? [[User:Gyozaplanet|Gyozaplanet]]&lt;br /&gt;
&lt;br /&gt;
I noticed the image for 1460 has been vandalized.  But, in looking at the history it shows an old vandalism that was fixed.  But following the link in the alleged fix gets the vandalized image.  I'm out of my depth for fixing this, but couldn't find a better place to report it.  It's getting too late and I'm far too tired to do more...  (As an aside to what I came here for, are the above two things vandalism here?  That's a rathole I'm not continuing down.)

&lt;br /&gt;
&lt;br /&gt;
A few hours ago I decided to visit this wiki, and got quite the surprise on the front page, in that it was heavily vandalized. Decided to make an account after looking at recent changes and saw how much there was.&lt;br /&gt;
&lt;br /&gt;
The accounts involved seem to be these;&lt;br /&gt;
* CobsonTheGemson&lt;br /&gt;
* ChuddyCobson&lt;br /&gt;
* Cobson&lt;br /&gt;
* Stinkycobbypoopoo&lt;br /&gt;
* Chud&lt;br /&gt;
* GotTheJakkyDoe&lt;br /&gt;
&lt;br /&gt;
Kinda confused since they don't seem to be bots but I assume they're using a script or something to automate their vandalism. As far as I know, A few other people and I reverted more or less everything those accounts have done but it's possible some stuff fell through the cracks.&lt;br /&gt;
&lt;br /&gt;
Also some of the gifs I reverted (most notably the gif for 381) seem to still have the same image so I'm hoping that's just a cache thing that'll sort itself out in time.&lt;br /&gt;
&lt;br /&gt;

There's trolls posting extremely obscene stuff on the homepage, and frankly I'm appalled.

: It's been like this forever.

::: I find it unfortunate that &amp;quot;rarity&amp;quot; is any sort of excuse for allowing this to happen. XKCD is a fantastic source of quality STEM entertainment, and thus is a great resource to get younger audiences interested in such fields through humor. Many high school age and younger people regularly view xkcd content. However, some of the comics are quite obscure or contain a lot of depth, which is why explainxkcd has been such a great resource for everyone to learn things that are outside of their depth (including younger audiences). The knowledge that someone can open explainxkcd and have the slightest chance that they see extreme gore/porn is absolutely absurd and unacceptable for a wiki that is serving solely family friendly science content. I can no longer recommend explainxkcd to people I know (and especially not younger people) because of the lack of modern anti-trolling tooling, and that really sucks. I understand the issues surrounding locking down the text explanations, but the images should be a trivially solvable problem. Compare a checksum between the image found at *.xkcd.com and the image uploaded and reject an image that doesn't match, or better yet *use the official xkcd RSS feed* (https://xkcd.com/rss.xml) to download the images directly, and don't allow any user edits of the images. Then you can deal with vandalization of the text some other time, locking down the images is really the highest priority here I think.

Actually, looking at [https://www.explainxkcd.com/wiki/index.php?title=Special:Log/newusers&amp;amp;limit=500&amp;amp;type=newusers&amp;amp;user= Special:Log/newusers] is pretty ominous. Nearly all of the last 500 (within the past 4 days), and also the next few thousand, are suspicious. The CAPTCHA probably needs to be replaced with something more difficult that is perhaps not as trivially automatable? And all those users blocked? Not sure. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 22:05, 4 July 2023 (UTC)&lt;br /&gt;
:As a regular checker of such things, I know for a fact that you get hundreds of 'suspicious' accounts created every day, and most of them 'go nowhere'. The account creation speedblocks may not be very good. Or, possibly, tens of thousands of accounts are ''tried'' to be created, with 'just' a small percentage of them getting past the CAPTCHA/etc to get noticed by us - the actual top-level site admins will have access to the 'failed to register fully' logs. ''But'', the actual page vandalism is very rarely any of these 'mechanised spam accounts'. I presume because the CAPTCHAs throttle down the 'lucky' accounts' abilities to do anything they were programmed to do ''once'' registered. And, no, the accounts aren't blocked (i.e. disabled accounts, except on very ''rare'' occasions when an Admin gets annoyed with a conspicuously used spam-login), if the actual Block Log is to be believed, but so many get created and ''never'' used so it looks like the &amp;quot;new user early posts&amp;quot; precautionary checks do a very good job.&lt;br /&gt;
:We're also getting that idiot (I presume the same idiot as we've had for a year or two now) who manually creates accounts, such as you have been dealing with (and me, and others) over the last 24 hours or so. As a stupid human rather than a 'smart' bot, the CAPTCHA is no block to him/her/them. And the occasional IP gets used in that way, too (and I mostly successfully revert vandalism as only an IP; usefully, I hope) which might just be lazy vandalism, on top of the baseline stupidity. But the precautions against them are different. As with the 'Eric's (&amp;quot;Hi, I see your website needs improving - Eric&amp;quot;-types of message), which also seem to be handled by the community (and/or our automated blocking/reverting).&lt;br /&gt;

:Instead, we should keep on keeping on. The community handles these things as they need to be.

== Vandalism on page 2805 ==&lt;br /&gt;
&lt;br /&gt;
The latest comic page (2805) is currently being vandalized. Can an admin please look into it?&lt;br /&gt;
&lt;br /&gt;
== Problem with new accounts and IPs ==&lt;br /&gt;
&lt;br /&gt;
So I'm sure many of you are well aware of the vandalism happening recently. But what concerns me the most is that all the edits were done by many, many different IPs, meaning that we can't just block one, and this site could get overrun by systematic IP vandalism. Also, the new accounts being created seem very suspicious. For such a small community, there's no way that there can be around 100 new users each day. The actual usernames of the users seem to follow a very repetitive pattern (generic first name + generic last name + random number). [[Special:Contributions/172.70.42.209|172.70.42.209]] 18:44, 24 July 2023 (UTC)&lt;br /&gt;
:As a fellow IP (and not a vandal myself, at least by intent) I find that the advantages of being able to leap in and correct (often 'named') damage outweigh the relatively small amount of IP-led vandalism. And the details of how the IPs represent the (limited, but geographically distributed) Cloudflare gateways has been noted before a number of times, together with what can be done about/with them.&lt;br /&gt;
:About the new accounts... Look back for ''years'', and you'll see the same (or similar) patterns. Almost all the truly rogue (presumably automated generation/'registering') then do nothing else as the site blocks the (still automated) attempts to do something with them.&lt;br /&gt;
:The worst danger this site is threatened by is the actual manually-posting individuals who (IPed or named) can do what they like so long as (like us legitimate editors) they are prepared to be sat at the keyboard and spend/waste the time in navigating the initial CAPTCHAs/etc to set down their changes. And there's not much more anybody can do about them without ruining everyone else's experience to a similar degree. Perhaps there's some adjustments possible, but none seem necesary to address the account-spam and other precautions are intercepting/reverting the lion's share of the edit-spam (with or without accounts).&lt;br /&gt;
:Not up to me, but I trust in those who it is up to. To continue with what is happening right now or to respond in new ways to anything that needs a new approach. Not saying that I don't have ideas of my own, for if I were able to intervene, but I doubt it'd be useful to voice them.

&lt;br /&gt;
== Large amounts of vandalism involving disturbing imagery. ==&lt;br /&gt;
&lt;br /&gt;
Page 2805 has a huge vandalism problem. Vandals (it seems to be the same few people over and over, or maybe one person with multiple addresses) keep covering the page with weird, disturbing photos and way-too-bright colors.&lt;br /&gt;
A few people have been valiantly fighting back but that doesn't mean this isn't a problem.&lt;br /&gt;
I would like to please request that the page be locked to prevent further vandalism, and that you please ban all the people that have vandalized it in this way before (and/or take some other action to prevent future vandals) . Thank you very much! [[User:(insert name here)|(insert name here)]] ([[User talk:(insert name here)|talk]]) 01:20, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
There also seems to be a parser problem where instead of vandals replacing the page source, the vandalism is appended to the end, even though it isn't in the source. [[Special:Contributions/172.71.174.230|172.71.174.230]] 03:39, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
The optimal way to go would be to add bots that automatically replace questionable content like divs and detect image/word spam (like the one in Wikipedia). They would always be on so the vandals would get overwhelmed. Similarly I'd suggest monitoring the constant stream of IP addresses and created accounts. Most editors are IP addresses though, so you might want to watch out for that. Does ExplainXKCD have semiprotection capabilities? You would definitely want to do that, especially the important articles like [[xkcd]], [[Randall Munroe]], [[Cueball]], [[1:_Barrel_-_Part_1]], and ALL of the templates (the vandals were targeting those the most). [[User:84596Gamma|84596Gamma]] ([[User talk:84596Gamma|talk]]) 11:53, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
: I agree that the important pages (primary pages, plus all templates) need to be protected somehow so that this can't happen again. It's nice to have a low threshold to editing; it's nicer having a resource that can be depended on and doesn't require random volunteers jumping in to save. (Let's be honest; the images the vandal posted could have been much, much worse.) -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 12:28, 25 July 2023 (UTC)&lt;br /&gt;

== Becoming an admin? ==&lt;br /&gt;
&lt;br /&gt;
Hi. I've been contributing occasionally for eight years now, and I think I've been helpful. But, almost half of the edits were last night in that wave of vandalism. It was very frustrating knowing that I had the same tools as the (14-year-old?) vandal, and the only end-point to the fun would be one of us throwing in the towel, and it was probably going to me (bedtime).&lt;br /&gt;
&lt;br /&gt;
I don't have the time and/or commitment to do regular moderation work, but I (think I) am a reasonable person, who deals with conflicts rationally and could help out in a pinch. Is there a chance I could be given some more powers to help out if (when) such a crap-storm happens again? Thanks for your consideration... -- [[User:Dtgriscom|Dtgriscom]] ([[User talk:Dtgriscom|talk]]) 11:14, 25 July 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
:I saw your efforts, early on in my own day, definitely looked to be amongst the helpful editors. I later picked up several cases (might have missed a couple, that others IDed before me) after I got online, and undid that latest form of vandalism in both templates (agree with above, they probably should be semi-protected) and pages. A simple Undo even at my level was sufficient to revert practically everything. What might have been handy was one of the top-moderators being around to use the mass-revert tools to streamline that, and keep on top of the account (or account''s'', as the problematic one would definitely open new accounts - we've seen them do this before) deserving to be blocked and banished. Unfortunately, the freedom of a wiki (which I value) doesn't really work well with over-administration. But that's a discussion to be had by those already at the top levels. I don't envy them.

No, that's not true: I'm looking for something that would make the battle ''unfair'' by making it easier to clean things up than it is to vandalize them. For instance, of the 123 vandalisms I reverted over the pat 24 hours, a third of them were from the top four IP addresses, and two thirds were from the top ten. If you only look at the first three quads of the IP addresses, half came from just two subnets. Block a few IP addresses, and the moderation load would go way down. (And that ignores the work the other users did.)&lt;br /&gt;

== Escape speed is no longer incomplete ==&lt;br /&gt;
&lt;br /&gt;
Can you delete the text at the top of every page except the main page that says ''&amp;quot;We still need to complete some explanations like this one: 2765: Escape Speed. All incomplete explanations are here.&amp;quot;''? Escape speed is no longer incomplete, so that is wrong.[[User:B_for_brain|B for brain]] ([[User_talk:B_for_brain|talk]]) ([https://www.youtube.com/channel/UCg4bo-hj-mDyOOUp_Yp0pug youtube channel] [https://bforbrain.weebly.com/ wobsite (supposed to be a blag)] 14:03, 27 December 2023 (UTC)&lt;br /&gt;

== Vandal Issue ==&lt;br /&gt;
&lt;br /&gt;
we've got vandals all over [[2875: 2024]], and they're getting persistent &amp;lt;span style=&amp;quot;font-family: 'Comic Sans MS'&amp;quot;&amp;gt;[[User:SomeoneIGuess|someone, i guess]]&amp;lt;sup&amp;gt;([[User talk:SomeoneIGuess|talk i guess]]&amp;amp;#124;[[Special:Contributions/SomeoneIGuess|le edit list]])&amp;lt;/sup&amp;gt;&amp;lt;/span&amp;gt;  16:50, 2 January 2024 (UTC)&lt;br /&gt;

::Deleting the vandal's ignorant... let's call it &amp;quot;self-defense&amp;quot; to be generous.

== XKCD Browser ==&lt;br /&gt;
&lt;br /&gt;
I made a [https://github.com/kristianbenoit/XKCD XKCD browser] in python with pygame and think it could be useful to others. The idea was to popup a comic the morning after it was published from a crontab. There could be a hotkey to point to todays discussion on explainxkcd. I wonder where/how would be the place to advertise it ? [[User:Kbenoit|Kbenoit]] ([[User talk:Kbenoit|talk]]) 15:36-40, 20 February 2024 (UTC)&lt;br /&gt;
:Here's a good start. Perhaps on the comic discussions for similar things ([https://uni.xkcd.com/ unixkcd], etc). As and when you get a User page here then you can perhaps expound on it there (assuning you aren't leaving the explanation to the github webspace.

Maybe indeed I should have pointed at [[UniXKCD]], or [[Talk:UniXKCD]], but I wasn't sure that was even the best place on here.

::I repeat that you (Kristian, with our help at bumping the contribution here) have already now made it known/knowable, at least to those who browse this site widely, but once you get a Userspace page you can perhaps do a little bit more in your own free space and also push people there through subtle pointers or signature-links in further on-context contributions. This isn't really a place for random advertising, but definitely contextual links to offsite xkcd 'fandom' is not something I'd personally have issues with (certainly compared to some other things that might get snuck on here).

== Vandalism-related Ban Request ==&lt;br /&gt;
&lt;br /&gt;
Hey, if any of the admins see this, can you please ban Jupitale? They’ve made 11 vandalism-related edits, within the time frame of about 21 hours. Even though they haven’t ben active since February 28, I feel like it’s better to err on the more cautious side. Thanks! ^_^ [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 01:09, 5 March 2024 (UTC)&lt;br /&gt;
:It'd be even more cautious not to [https://www.explainxkcd.com/wiki/index.php?title=User:Ash123&amp;amp;action=history create userpages] for a user that [https://www.explainxkcd.com/wiki/index.php?title=Talk:1211:_Birds_and_Dinosaurs&amp;amp;diff=prev&amp;amp;oldid=336532 was only here to spam us].. (Note to admins: add Ash123 to that todo list, if we're calling them out, and I know I've reverted some other single-spamming usernames recently.) But you just know that a ban for anyone like 'Jupitale' (as much as they'd deserve it) is going to be of no actual consequence to them.&lt;br /&gt;
:And hold off on all those other userpages, 42. It's not your job, and you might not be right about the usefulness of the ones you're (seemingly randomly) creating. Without even being asked.  [[Special:Contributions/172.69.194.217|172.69.194.217]] 01:55, 5 March 2024 (UTC)&lt;br /&gt;

Can we please have an xkcd-like countdown on the top of every page for how many days left till the next april fool's comic?

:What certainty is there that there'll be one? If/when get the April Fool, or past it, do we reset for the next, or start counting down to the next hypothetical New Year, Christmas, Halloween comic or &amp;quot;Two/Seven/Ten Years&amp;quot; reanniversary? We need to know a few more details to the idea.&lt;br /&gt;
:And I presume you meant &amp;quot;a countdown in a suitably xkcx-ish manner, as there have been countdowns for books/etc but not a consistent approach, just some wide ranging but apt creative teasers [[Special:Contributions/172.69.194.225|172.69.194.225]] 11:32, 25 March 2024 (UTC)&lt;br /&gt;

== Unblock request ==&lt;br /&gt;
&lt;br /&gt;
Hello! I tried to sign up for an account a couple years ago, but I happened to sign up during a major vandal attack, and an admin blocked me based on a mistaken accusation of vandalism and sockpuppetry. I had used the account [[User:Danny E. Corchado]], then I used [[User:Danny Corchado]] to attempt to appeal my block shortly afterwards; both accounts are now blocked. I no longer have the password to the former, but I can log in to the latter account. Can someone please unblock [[User:Danny Corchado]]? If someone creates [[User talk:Danny Corchado]], I should be able to edit that page to prove I do control the account.

::Really? You actually think this could work like that? Both(/'both'?) of you? I wondered why you (42) randomly created that user's page from (from 'your' perspective) the mists of time. Which doesn't help unblock anyone, there's not even any logic in that request. (Once unblocked, whoever controls the account can prove that ''they control the account''. But where does that lead anyone?)&lt;br /&gt;
::And why would you associate ''in any way'' with an account 'of no account' that was linked with vandalism? You can only be judged by your actions, as you can choose any name (within reason) that you want. &amp;quot;Mr Corchado&amp;quot; still has uncounted options left if he absolutely must post, in all good faith, as 'Dan Corchado' or similar. You've been here long enough (longer than your current username) to know all this. Sheesh... [[Special:Contributions/172.70.85.77|172.70.85.77]] 11:03, 1 April 2024 (UTC)&lt;br /&gt;

== Main Page Deletion ==&lt;br /&gt;
&lt;br /&gt;
Hi. When I logged in today, I saw that the Main Page was deleted just 2 minutes before by Mark Hurd. If I remember correctly, he was confirmed to have passed on Wikipedia, and other Admins were talking about de-sysopping him. Can someone please explain this? Thanks, [[User:42.book.addict|42.book.addict]] ([[User talk:42.book.addict|talk]]) 15:44, 11 April 2024 (UTC)&lt;br /&gt;

== &amp;quot;Interesting&amp;quot; Account Creations ==&lt;br /&gt;
&lt;br /&gt;
Hi. So I was looking at the user creation log, and I noticed a suspicious number of accounts-at least 90% of them-are being created using a &amp;lt;Semi-generic first name&amp;gt; &amp;lt;semi-generic last name&amp;gt; &amp;lt;usally two or three numbers&amp;gt;. This would be kinda weird in the first place, however, almost none of the accounts are active. That and the fact that these accounts are being created no less than 10 minutes from each other made me think somethings a little weird. Maybe I'm just dumb. Just wanted to bring it to your attention in case this wasn't a normal thing.[[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 17:17, 15 April 2024 (UTC)&lt;br /&gt;
I looked a bit further, the exact same thing happened two months ago as well, but the names were random letters instead [[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 17:34, 15 April 2024 (UTC)&lt;br /&gt;
:It's been happening (in various forms) for years. Maybe a decade, if not more. For as long as I've been paying attention, certainly, which might well be that long.&lt;br /&gt;
:Without access to the whole admin logs, it seems to reflect the intention of 'bots to spam, spam and spam again, automatically, creating accounts they will use to do so but then hitting the actually rather effective anti-bot defenses, so they do absolutely nothing (well, maybe they're lucky every now and again, but practically insignificant successes, and IP-only spams seem to dominate, at maybe twice a week for who-knows-how-many wctual attempts).&lt;br /&gt;
:Amongst the current bunch randomly created names, I see a few that are clearly created around the word &amp;quot;Ingredients&amp;quot; (rather than a feedstock to create 'FirstnameLastname', which has long been the main default). I take it that each meta-pattern we see as indicative of a different bot-farmer's efforts, so this might have been started up for a particular spam-theme. Which maybe we'll get an idea of if it gets lucky. Though I'm in no hurry to find out such details. [[Special:Contributions/172.71.242.13|172.71.242.13]] 12:39, 16 April 2024 (UTC)&lt;br /&gt;
