This comic depicts an attempted connection of three {{w|Ferris wheel}}s using a {{w|Belt (mechanical)|mechanical belt drive}}, a system typically used to transfer motion between rotating shafts. By connecting the wheels at different circumferences, the relative motion is geared up or down. If the belt passes around the circumference of one wheel and is connected around the hub of another, the latter will rotate significantly faster. In this case, the second wheel's circumference is in turn connected to a third wheel's hub, resulting in even greater rotational velocity. However, this setup is mechanically unsound and possibly dangerous, as Ferris wheels are not intended to be connected in this way.{{cn}} As shown, the first wheel on the left is running at a normal speed, while the other two are rotating increasingly fast, leading to a potentially hazardous situation where passengers are flung around to various (possibly {{w|G-force#Human tolerance|quite hazardous}}) extents.

Ferris wheels can vary widely in size and speed of rotation, but for illustration, let us assume a diameter of about 200 feet (60 m) and around 10 minutes per full rotation. The apparent ratio between the connected wheels in the comic is approximately 12.5:1, meaning the motion is significantly sped up as it’s transferred. The second Ferris wheel, driven by the first, could spin at around 1.3 rpm, with passengers moving at 9 mph (14 km/h), which is faster than usual but not inherently dangerous, depending on how the wheel and its carriages are engineered. However, when this motion is further transferred to the third Ferris wheel, it could spin at 16 rpm, with passengers traveling at over 110 mph (180 km/h), subjecting them to 8 Gs of force—conditions that would be hazardous.

In the caption [[Randall]] says that he was fired for this ill-advised modification, highlighting the impracticality and dangers of the idea. A cruise line also fired the cartoonist due to an unsound engineering proposal earlier in [[2935: Ocean Loop]].

The title text imagines the consequences of leaving the belt drive system in place but switching which wheel is powered. If the most extreme wheel (the third one on the right) is powered, the gearing would be reversed, making for a possibly pleasant and normal ride on the right-hand wheel, but rendering the experiences of the riders on the other two wheels far too slow for an enjoyable carnival ride. One revolution of the center wheel might take two hours and five minutes, while the left wheel would take more than a day (twenty-six hours to be exact)  per revolution.    This exaggerates the impracticality and unintended effects of using a belt drive system on Ferris wheels, humorously illustrating how such an idea would lead to absurdly varied ride experiences.

==Transcript==
:[Three Ferris wheels are shown side by side, with some people stood on the ground for scale. Each of the first two wheels has a belt connecting its circumference to the axle of the wheel to its right. "Agitrons" indicate that the middle wheel is turning notably faster than the left wheel, with the gondolas seen to be rocking significantly at all points round the wheel. The spokes of the right wheel are completely replaced by "motion lines", indicating that the the right wheel is turning the fastest of all. All its gondolas are hanging outwards against centripetal force, interspersed with their own motion lines.]

:[Caption below the panel:]
:The county fair fired me for adding a belt drive to the Ferris wheels.

==Trivia==
The first (slowest) wheel can be seen to notably lack a 'spoke' at approximately the five'o'clock position, supporting the point where its respective passenger seating is hung. Clearly, however, the wheel design is strong enough to withstand much greater forces in the other two versions of the wheel (which appears to be complete in the case of the second, though the thin spokes are only seen as blurs in the third wheel) suggesting that there may not be significant danger from this omission. It does not bode well, however, for general {{w|Occupational Safety and Health Administration|OSHA compliance}} in how they erect/maintain the rides, even before the belt-drive idea added its own issues.

Talk:2970: Meteor Shower PSA

2024-08-11T12:11:53Z

172.70.163.121:

Pretty sure the term "contact binary" in this instance is referring to the small solar system body variety (a peanut asteroid) rather than a contact binary star, but I can't think of a way to explain that in the explanation.[[User:RegularSizedGuy|RegularSizedGuy]] ([[User talk:RegularSizedGuy|talk]]) 06:11, 10 August 2024 (UTC)

Amongst other things, if you ever see a space-rock fall, and land, don't be tempted to just pick it up. It will probably be extremely cold, for a while. And you don't want to leave your sticky fingerprints on it (or, maybe, {{w|Venom (character)|its sticky fingerprints on you}}). If you have a handy (clean) container then perhaps you could scoop it up to stop it from getting lost/soiled where it lies, unless you get more immediate advice directly from experts who might be very interested. (Depends upon who you talk to, and when, but there [https://ukfall.org.uk/report-a-meteorite/ may be some standing advice] that you can follow, if you're not lucky enough to already be an expert in the subject out looking for a particular find.) [[Special:Contributions/172.71.26.87|172.71.26.87]] 14:09, 10 August 2024 (UTC)

It seems to me that the "more dangerous examples" should link to something along the lines of SF stories in which infectious material came to Earth via meteorite. The "Green Rocks" link is more about how sci-fi (term used advisedly) alien substances (including meteorites) can have any magic powers the plot needs. I'm trying to come up with examples, but all that's coming to mind immediately is Walter M. Miller Jr.'s "Dark Benediction". [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 01:07, 11 August 2024 (UTC)
:I (as that editor, and of the prior comment here) had the same difficulty. Even a wikiwalk (or, indeed, a tvtropeswalk) didn't seem to give what I thought was there. I mention the Venom symbiote, above (a near-example; most cases of it, in various continuities, seem to have it being ''brought'' to Earth... if it 'fell in the open' it was part of a sample-return mission crashing and burning), and there are a number of other "mysterious rock falls which 'infects' the locals who find it and touch it" (much parodied and repeated) but I could not find the unambiguous ur-example or whatever 'famously made it famous' in any real sense.
:Green Rocks does have a lot of (obvious) memetic overlap with Smallville and similar treatments around that continuity/canon. (I was mostly worrying that in that case, Clarke aside, pretty much everyone who got 'green rocked' ''at least at first'' found the effects beneficial ...it's where they took that, and/or hidden psychological compulsions, that might have been their ultimate downfall. Or at least quickly found themselves uniquely isolated from society due to unwanted death-prognistication skills/whatever.)
:It was just a bit of a chuck-it-in, really. Had also been looking at non-meteoric examples. Such as if a soviet satellite's RTG landed, 'intact', you might be wise not to just hold it, or the fictional nuclear weapon discovered by farmers in Sum Of All Fears, or the non-fictional (but not 'loaded') [https://www.bbc.co.uk/news/world-us-canada-68189568 real-life equivalent] that luckily wasn't as dangerous as a true Broken Arrow would have been.
:So make of it what you want. I tried to keep the Explanation aside short and sweet, rather than overly explain the joke, but doubtless someone else can refine it (or excise it) in ways that I never found able to. [[Special:Contributions/172.70.163.121|172.70.163.121]] 12:11, 11 August 2024 (UTC)

The bit in the explanation stating that animals might abandon their young if it smells of humans should be removed. That's a myth. --[[Special:Contributions/172.71.22.155|172.71.22.155]] 03:22, 11 August 2024 (UTC)

860: Never Do This

2024-08-05T10:17:42Z

172.70.163.121: /* Explanation */ 'Improved' on link-to-tvtropes (local site template)

{{comic
| number = 860
| date = February 14, 2011
| title = Never Do This
| image = never_do_this.png
| titletext = I call Rule 34 on The Secret House.
}}

==Explanation==
[[Cueball]] shows his new pocket {{w|microscope}} to [[Megan]]. With the curiosity of scientists, they quickly decide to use the microscope to look at a number of different things.

But after they use the microscope to inspect what is under their fingernails, they're both aghast at what they find and {{tvtropes|TroubledFetalPosition|curl into fetal positions}}. Our fingers are how we interact with the world, and all manner of things get trapped under our fingernails; different kinds of dirt, fungus, spores, fragments of insects, insect droppings and so on. Such things that obviously look pretty horrific when magnified a few hundred times. Cueball and Megan never suspected what they would find, and seem unable to process or deal with the horror they have uncovered.

The title text refers to {{w|Rule 34 (Internet meme)|Rule 34}} (see [[305: Rule 34]]), an {{w|internet meme}} which states "If it exists, there is porn of it. No exceptions.". The book referenced is "The Secret House: 24 hours in the strange & wonderful world in which we spend our nights and days" by {{w|David Bodanis}} and is a study in {{w|micrograph|microphotography}}. It features extreme close-ups of everyday phenomena in the common house, but as seen from a microscopic perspective. "Rule 34" states that there must be porn of this nature, but it is not clear what form this would take; it could be lewd drawings of {{w|Moe anthropomorphism|personified}} microscopic objects, or perhaps just images of individual {{w|sperm cells}}.

[[Randall]] may have done this check himself - and now chooses to warn others not to make the same mistake. Thus, the title: '''Never Do This'''. He later gives the same type of advice against using a UV lamp in the bathroom through this comic: [[1469: UV]].

Given his likely negative feelings towards {{w|Valentine's Day}}, as seen in the most of his [[:Category:Valentines|Valentines comics]], it may not be a coincidence he send this gross comic out on February 14. He did not draw any Valentines related comic this year as he for instance did the two years before and the year after.

:Cueball: Check it out—a pocket microscope!
:Megan: Ooh! Let's look at stuff!

:[Cueball holds a pencil; Megan peers at a quarter through the microscope.]

:Cueball: Let's look at the skin under our fingernails!

{{incomplete|Created by 10 MORE THAN AVERAGE MATH TEACHERS - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

The comic depicts various similarly formatted examination questions that might appear on test papers at various points in a student's potential academic career. While they all share a similar feel, they are asking for different things, some of which might be considered more serious and examinable proofs of study than others. The joke is that the first and last questions are the same, but have very different interpretations based on the context.
{| class="wikitable"
|+ Exam numbers
! Exam level !! Question !! Answer
|-
| {{w|Kindergarten}} math || Write down the biggest number you can think of || At a kindergarten-level education, it is assumed that an individual might write down a relatively small number like 300, depending upon whether they have encountered the concept of hundreds. It might also be interpreted as "what's the highest number that you (think you) can count up to". Given the nature of a child's exuberant glee at learning about ''really'' big (but otherwise normal) numbers, they may even try an answer something like "a million billion squillion gazillion... and seven!". It is not certain what criteria would be used to mark this question correct or otherwise, it may actually be a stealth question in child psychology or a question that everybody "gets right" so long as they answer it.
|-
| Pre-{{w|algebra}} || Write down the value of x if x=3x-8 ||

''3x'' refers to the multiplication of 3 and the originally unknown number ''x'', as a convenient shorthand.

By subtracting ''3x'' from both sides, ''-2x = -8''. Divide both sides by -2 to find ''x''=4. Alternately, subtract ''x'' from both sides to give ''0 = 2x - 8'', and as taking 8 from two ''x''s makes it zero, one ''x'' is half that

(Verify by plugging ''x''=4 into the original equation. '''4''' = (3*'''4''') - 8 -> '''4''' = 12 - 8 -> '''4''' = 4.)

Also the subject of [[221: Random Number]].

|-
| {{w|Calculus}} || Write down the value of ∫0π x sin2 x dx ||
The integral can be solved using {{w|List_of_trigonometric_identities#Power-reduction_formulae|a trigonometric identity}} and [https://math.libretexts.org/Bookshelves/Calculus/Calculus_(OpenStax)/07%3A_Techniques_of_Integration/7.01%3A_Integration_by_Parts integration by parts]:

∫0π x sin2 x dx

= ∫0π x (1-cos 2x)/2 dx

= ½ ∫0π x dx - ½ ∫0π x cos 2x dx

= ¼ x2 |0π - ¼ ∫0π x (sin 2x)’ dx

= ¼ x2 |0π - ¼ x sin 2x |0π + ¼ ∫0π (x)’ sin 2x dx

= ¼ x2 |0π - ¼ x sin 2x |0π + ¼ ∫0π sin 2x dx

= ¼ x2 |0π - ¼ x sin 2x |0π - ⅛ cos 2x |0π

= ¼ π2 = 2.4674...

|-
| PhD {{w|Cosmology}} || Write down the Hubble constant to within 1% || The Hubble constant is a component of {{w|Hubble's law}}, which describes the relationship between the distance between galaxies and their speed of separation. Its exact value is not known to this level of precision; it is ''about'' 70 (km/s)/Mpc. Different methods of measuring it have come up with significantly different values, with their own error-bars generally of 2% to 5% (both plus and minus, or assymetrically but with a similar overall range) and resolving this difference (the {{w|Hubble's law#Hubble tension|Hubble tension}}) is one of the great challenges of modern cosmology. PhDs involve advancing their field, so it seems this particular PhD student has completed a thesis solving this problem. This question might have a different acceptable answer if asked again of the student, depending upon further developments in cosmology, and the 'constant' itself is supposed to change over cosmological time (the nature of this change being yet another subject requiring further study, calculation and observation).

What would a correct answer look like? Perhaps 69.9 (km/s)/Mpc.
|-
| {{w|Game Theory}} || Write down 10 more than the average of the class's answers || Game Theory studies "games" (and 'game-like' situations) in which two or more participants take actions that will succeed or fail based on other participants' decisions. In this case, all students' answers will be averaged (likely a simple {{w|arithmetical mean}}), and the best answer would be one that is 10 more than that average.

For instance, if the answers end up being 30, 40, 50, 60, and 70, the (mean) average would be 50, making 60 the best possible answer. As an individual test taker who doesn't know what your classmates are going to write down, the objective is to answer 10 more than your estimate of the average (taking into account your own guess), ''knowing that everyone else will be doing the same.''

Something similar to this question is found in the title text of [[2385: Final Exam]].
|-
| Postgraduate Math || Write down the biggest number you can think of || This question echoes the very first example, but would be expected to be answered very differently (unlike a revisiting of most of the others).
Postgraduate math students can probably think of ''very'' large numbers. While a tempting answer could be "{{w|infinity}}", most mathematicians do not consider infinity to be a number, but rather a class of numbers. (Writing down "Infinity" in this context would be as wrong as writing down "Primes" or "Positive integers"). Even if infinity is an acceptable answer, some infinities are bigger than others. Students familiar with the field of [https://googology.fandom.com/wiki/Googology#History Googology] may give an answer such as [https://en.wikipedia.org/wiki/Rayo%27s_number Rayo's Number], which was the winning entry in the [https://googology.fandom.com/wiki/Big_Number_Duel Big Number Duel].

This might heavily depend upon the branch of mathematics you are studying. Named (finite) numbers, or ones with specific and useful notations, might satisfy some questioning contexts, whilst the existence of a whole further set of trans-finite numbers (i.e. increasingly large types of "infinity") would be important considerations in others. For those associated with more computational mathematics, any infinity would be {{w|NaN|Not a Number}}, and their answer might instead be the ceiling of some binary representation (typically ''28n-1'' for some value of ''n''), the largest unsigned value reliably storable in a given byte form for an integer (e.g. a {{w|Integer (computer science)|double quadword}}). On the other end of the spectrum, many abstract algebraists might answer with some variation of "What ring are we working in, and is it even well ordered?" It also might be a trick question: if you can envision a real number greater than one, are you even doing real math (in a given field)?

As with the kindergarten question, there may be no previously anticipated "correct" answer. It could be another "correct just so long as you answer it" (or perhaps "sensibly" so) or the mark goes only to those giving the greatest valid number across all submissions.
|-
| {{w|Calligraphy}} (title text) || Write down the number 37, spelled out, nicely || Calligraphy is the art of artistic writing. The title text expands the joke outside the realm of math and points out that since calligraphy does not require any math skills, the only way a calligraphy exam would even mention numbers is if one had to write them out in such a way as to showcase their calligraphic skill and aesthetic judgement (choosing a form and adornment of script that is "nice", which may be a highly subjective choice). In this case, it could be rendered as "thirty-seven" or "thirty seven", or possibly, "one score and seventeen" in old-fashioned writing. The subject may choose to render it in a language other than English — for example "dau ar bymtheg ar hugain" would provide significant scope to show off calligraphic skill. {{w|37}} is a number that some people believe [http://thirty-seven.org mysteriously appears more often than it should]; this was a subject of a [https://www.youtube.com/watch?v=d6iQrh2TK98 recent Veritasium video].
|}

This style of final exam question, un-numbered and therefore possibly the ''only'' question upon the whole of each final paper, in some ways (for some instances) echoes the question "What is your name?" that Randall will be aware was the sole question given to Discworld's {{w|List of Discworld characters#Victor Tugelbend|Victor Tugelbend}} in an attempt to ensure he comprehensively passed (or utterly failed) his final student-wizard's exam, after many prior times of deliberately not-quite-passing.

2966: Exam Numbers

The comic depicts various similarly formatted examination questions that might appear on test papers at various points in a student's potential academic career. While they all share a similar feel, they are asking for different things, some of which might be considered more serious and examinable proofs of study than others. The joke is that the first and last questions are the same, but have very different interpretations based on the context.
{| class="wikitable"
|+ Exam numbers
! Exam level !! Question !! Answer
|-
| {{w|Kindergarten}} math || Write down the biggest number you can think of || At a kindergarten-level education, it is assumed that an individual might write down a relatively small number like 300, depending upon whether they have encountered the concept of hundreds. It might also be interpreted as "what's the highest number that you (think you) can count up to". Given the nature of a child's exuberant glee at learning about ''really'' big (but otherwise normal) numbers, they may even try an answer something like "a million billion squillion gazillion". It is not certain what criteria would be used to mark this question correct or otherwise, it may actually by a stealth question in child psychology or a question that everybody "gets right" so long as they answer it.
|-
| Pre-{{w|algebra}} || Write down the value of x if x=3x-8 ||

''3x'' refers to the multiplication of 3 and the originally unknown number ''x'', as a convenient shorthand.

By subtracting ''3x'' from both sides, ''-2x = -8''. Divide both sides by -2 to find ''x''=4. Alternately, subtract ''x'' from both sides to give ''0 = 2x - 8'', and as taking 8 from two ''x''s makes it zero, one ''x'' is half that

(Verify by plugging ''x''=4 into the original equation. '''4''' = (3*'''4''') - 8 -> '''4''' = 12 - 8 -> '''4''' = 4.)
|-
| {{w|Calculus}} || Write down the value of ∫0π x sin2 x dx || The integral of the expression is ''((x-sin(2*x))*2*x-cos(2*x))/8 + C''. Plugging in values for ''x'' gives the result as π2/4 = 2.4674...

If one assumes sin2 is an {{w|iterated function}} instead of a square, one instead gets π2{{w|Struve function|H0(1)}}/2 = 2.8062...
|-
| PhD {{w|Cosmology}} || Write down the Hubble constant to within 1% || The Hubble constant is a component of {{w|Hubble%27s_law|Hubble's law}}, which describes the relationship between the distance between galaxies and their speed of separation. Its exact value is not known to this level of accuracy; it is about 2.3×10-18 Hz. Different methods of measuring it have come up with significantly different values, and resolving this difference (the {{w|Hubble's_law#Hubble_tension|Hubble tension}}) is one of the great challenges of modern cosmology. This question might have a different acceptable answer in the future, depending upon further developments in cosmology (although the 'constant' itself changes over time).
|-
| {{w|Game Theory}} || Write down 10 more than the average of the class's answers || Game Theory studies "games" (and 'game-like' situations) in which two or more participants take actions that will succeed or fail based on other participants' decisions. In this case, all students' answers will be averaged (what kind of average is not stated, but the common assumption would be an {{w|arithmetical mean}}), and the highest- (or perhaps only) scoring answer will be one that is 10 more than that average.

If a student knew what everyone else was thinking, this would incentivise them to answer 10 more than the consensus (taking into account their own forthcoming answer), which would not necessarily be the largest number written down. For instance, if the answers end up being 30, 40, 50, 60, and 70, the (mean) average would be 50, making 60 the most correct answer. Since they presumably do not know each other's answers, they will have to guess what those answers are likely to be, factoring in that each of the other students will also be guessing everyone's answers and responding accordingly.

In reality, most game theory exams test your understanding of game theory as an academic subject, not your ability to win games. (A type of class where actual results may result in better grades is a business negotiation class where the results of practice negotiations can determine one's grade on the assignment.)

Something similar to this question is found in the title text of [[2385: Final Exam]].
|-
| Postgraduate Math || Write down the biggest number you can think of || This question echoes the very first example, but would be expected to be answered very differently (unlike a revisiting of most of the others).
Postgraduate math students can probably think of ''very'' large numbers. While the "best" answer could be "{{w|infinity}}" (since, depending on your definition of the word "number", infinity may be the largest possible number that you will have encountered), students familiar with the field of [https://googology.fandom.com/wiki/Googology#History Googology] may consider infinity a concept rather than a number, and might give an answer such as Rayo's Number, which was the winning entry in the [https://googology.fandom.com/wiki/Big_Number_Duel Big Number Duel]. Even if infinity is an acceptable answer, some infinities are bigger than others.

This might heavily depend upon the branch of mathematics you are studying. However, as named (finite) numbers, or ones with specific and useful notations, might satisfy some questioning contexts, whilst the existence of a whole further set of trans-finite numbers (i.e. increasingly large types of "infinity") would be important considerations in others. For those associated with more computational mathematics, any infinity be {{w|NaN|Not a Number}}, and their answer might instead be the ceiling of some binary representation (typically ''28n-1'' for some value of ''n''), the largest value reliably storable in byte form (e.g. a {{w|Integer (computer science)|double quadword}}).

As with the kindergarten question, there may be no previously anticipated "correct" answer. It could be another "correct just so long as you answer it" (or perhaps "sensibly" so) or the mark goes only to those giving the greatest number across all submissions.
|-
| {{w|Calligraphy}} (title text) || Write down the number 37, spelled out (as "thirty-seven" or "thirty seven"), nicely || Calligraphy is the art of artistic writing. The title text expands the joke outside the realm of math and points out that since calligraphy does not require any math skills, the only way a calligraphy exam would even mention numbers is if one had to write them out in such a way as to showcase their calligraphic skill. {{w|37}} is a number that some people believe [http://thirty-seven.org mysteriously appears more often than it should]; this was a subject of a [https://www.youtube.com/watch?v=d6iQrh2TK98 recent Veritasium video].
|}

This final exam question, un-numbered and therefore possibly the ''only'' question upon the whole of each final paper, in some ways (for some instances) echoes the question "What is your name?" that Randall will be aware was the sole question given to Discworld's {{w|List of Discworld characters#Victor Tugelbend|Victor Tugelbend}} in an attempt to ensure he comprehensively passed (or utterly failed) his final student-wizard's exam, after many prior times of deliberately not-quite-passing.

2964: Olympic Sports

2024-07-29T16:12:06Z

172.70.163.121: /* Explanation */

{{comic
| number = 2964
| date = July 26, 2024
| title = Olympic Sports
| image = olympic_sports_2x.png
| imagesize = 553x328px

}}

==Explanation==
{{incomplete|Created by A VERY CONCERNED OLYMPIC OFFICIAL - Provide an explanation of each sport for the convenience of those unfamiliar with some or all listed sports. Do NOT delete this tag too soon.}}

This comic was officially published on the day of the opening ceremony of the {{w|2024 Summer Olympics|2024 Paris (Summer) Olympics}}, though it actually appeared early the following day.

In this comic, [[Randall]], who has no athletic training, imagines himself participating in various Olympic events, with his degrees of failure measured in terms of their humor potential.

{| class="wikitable"
|+ Olympic sports ranked by how funny it would be if a regular person competed
! How funny !! Sport !! Reason !! Depiction
|-
|rowspan=5| Not that funny || {{w|Rowing}} - One or more people row a boat to a destination.|| The person would struggle to row effectively, falling out of cadence and fouling the oars of the other rowers in their boat. However, if Randall competed in the single sculls, such coordination would not be an issue, and he would likely just be much slower than the other competitors. Or fall in the water. ||
|-
| {{w|Fencing}} - Two contestants attempt to land hits on each other with a long fencing weapon.|| They might fail to land any hits, but it wouldn't be overly humorous. Randall is evidently not masochistic enough to consider putting on protective equipment disastrously wrong and hospitalization funny. ||
|-
| {{w|Weightlifting}} || They might just fail to lift the weights. ||
|-
| {{w|Golf}} - Contestants attempt to hit, with golf clubs, a golf ball into one or more holes in as small a number of hits as possible.|| They would likely miss the ball or hit poorly, due to an incorrect stance/swing when hitting, using a club whose loft (angle of the front face) is inappropriate, or just basic lack of skill. || The illustration depicts Randall missing the hole at very close range.
|-
| {{w|Archery}} - Using a bow and arrow, contestants attempt to hit a target with as much accuracy as possible.|| Arrows might miss the target, but it's not particularly amusing (unless Randall forgoes armbraces & discovers the bowstring's propensity for smacking the inside of his wrist after releasing it). || Randall misses all his shots on the target.
|-
|rowspan=5| Pretty funny || {{w|Swimming}} - Contestants swim to a destination or complete lengths as fast as possible.|| They might struggle to stay afloat (particularly in open water swimming, where they would be buffeted by other contestants) or [https://en.wikipedia.org/wiki/Eric_Moussambani swim awkwardly]. They are also likely to have a markedly different physique to the other competitors, which would have a comic effect. ||
|-
| {{w|Long jump}} - Contestants, with a running start, attempt to jump as far as possible.|| They would likely make a very short jump, or perhaps foul every jump. ||
|-
| {{w|Pole vault}} - Using a bendable pole, contestants attempt to propel (vault) themselves over a bar.|| They might miss the plant and end up dropping the pole and running under the bar. If they did manage to get some lift, but failed to get enough to reach the mat, it would probably be concerning, rather than funny. ||
|-
| {{w|Diving}} - Contestants attempt to fulfil multiple criteria while diving into water.|| Awkward or painful-looking dives could ensue. Potential for injury would be high. ||
|-
| {{w|Hurdles}} - Contestants run on a track with hurdles positioned at various places.|| They might trip and fall over the hurdles, or just knock them all over as they fail to clear them. || Randall repeatedly and unpleasantly runs into the hurdles, unable to jump over any of them. He has his arm raised bent in front of his face in a classic hurdler's pose, but appears to have failed to get much, if any, height off the ground.
|-
|rowspan=5| Incredibly funny || {{w|Figure skating}} [The only Winter Olympic discipline featured in the main comic]|| They might slip and fall continually on the ice (high risk for sprained joints or bone fractures). This might have particular comic potential if Randall were skating as part of a pair, awkwardly attempting to lift and spin a partner, or perhaps doing nothing but being lifted and dragged around by them. ||
|-
| {{w|Horizontal bar}} - A horizontal bar is used to perform gymnastics.|| They might fail to perform any flips or lose their grip on the bar, falling to the safety mats below. In all likelihood, having been lifted to the bar, they would simply hang helplessly beneath it, managing minimal swings backwards and forwards. ||
|-
| {{w|Equestrian sports}} - Various activities involving the use of horses.|| They might struggle to control the horse or fall/get thrown off. || Randall is completely unable to control his horse. He is in the process of falling off and is flailing his arms.
|-
| {{w|Freestyle BMX}} - Contestants ride BMX bikes and perform various tricks, and are then judged by trick quality.|| They might crash or fail to perform tricks. ||
|-
| {{w|Pommel horse}} - Using a gymnastic device somewhat similar to a horse, gymnasts perform various tricks.|| They might awkwardly flop around, fall off, or slip their balance & risk crushing {{tvtropes|GroinAttack|a particularly squashy part}} of their anatomy, which could, depending on one's sense of humor, the context, & the exact aesthetics of the incident, elicit laughter. || Randall is attempting to perform a routine but clearly is not very graceful, balanced or typically dynamic, as made apparent by the rather basic {{w|The_Lexicon_of_Comicana|agitrons}} surrounding him. However, he seems to be unaware of this, excitedly demanding that people look at what he presumably thinks is an impressive feat of athleticism.
|}

The title text may be a reference to ski jumper {{w|Vinko Bogataj}}, whose spectacular crash at a (non-Olympic) ski flying event in 1970 in Oberstdorf, (then) West Germany became emblematic of the expression "the agony of defeat" in the opening narration of the popular US television program "{{w|Wide World of Sports (American TV program)|Wide World of Sports}}". Alternatively the reference may be to {{w|Eddie the Eagle}}, whose poor performance at the {{w|1988 Winter Olympics}} led to the introduction of the top 50 or 30% qualifying rule.

Two page moves later (because I made a typo in the first move), I realized that the category's name was correct and that someone had earlier linked to a nonexistent category that was not mine.

:Hi. I was just trying to submit the following, and got Edit Conflicted about it. Right, then. Obviously it's too late to make my reasoning known (I thought it was an IP who had created the "Charts with Confusion Matrices", or whatever it was, who couldn't have even created the required page, but... well, talk about confusion!) but giving it here anyway...
Removed the category of something to do with "confusion charts", which might be something to do with the appearence as a cross-compare table (akin to a Punnet Square, not ''quite'' the same as a Karnaugh Map; probably has some name such as "compatability matrix", but I can't remember or find what that might be). Anyway, apparently "confusion chart/square/matrix/whatever" isn't a term in use that I've been able to find out there in the real world (also, it is probably supposed to guide one ''away'' from potential confusion, not cause it), it specifically doesn't have a wikipedia entry (or even a wikiledia redirect to another one by another name) and we don't have that category even if we invented the term ourselves. There are other examples of this form already under [[:Category:Charts]], so it's "a thing" that we might want to service with a Category (ideally more "Compatability Matrix" than that other name), but best to create the category and add the comic(s) as members rather than speculatively add spurious non-existent categories then rely on someone else to fulfil them at a later date. Even better to have a quick check to see if everyone agrees to the category title (and need, ...which I would actually tentatively support, in this case, if asked) beforehand.
:...just as a note, as I spent quite some time trying to find out if "confusion charts" were a thing (and coming up blank), so maybe this way I haven't wasted my time quite as much as just going away, or instead just offering a laconic apology for getting in the way.

::Ok, me again. It looks like someone found {{w|Confusion matrix}} after all, as a wikipage. I'd actually looked for various "confusion" things but... Perhaps typoed the search when I tried vs. "matrix"..? Maybe. Seems the most logical mistake to have made. So ignore my above objections. Still, I don't like the name ("deconfusion matrix" would be awful, yet better), and I've never known it by that name. Just left making my opinion known, now, however wrong it turns out to have been.

:That would depend.
When asked "How do you deal with endquote punctuation in quoted speech?" he answered "Yes," with a definite nod of his head, "I would always try to put the punctuation before the quote."
:...that is how I was taught to do it, <mumble>fumphty-fumph</mumble> 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).
On the other hand providing "a set of words", with no clear quotation to them, ellicits no such compunction.
:...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 "a set of words," to be sensible.
If you give a "list", "spread" or "set" of singular terms then no, or even compounded ones if they are ultimately the "be-all" and "end-all".
:...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 "literal", insofar as meaning, or somewhat 'ad hoc', 'foreignish' or just plain constructed.
: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 "...at the end of a sentence (an aside.)", which should have been "... (an aside)." instead, or "(As a whole aside of its own)." for which it ''must'' surely be "(As ... of its own.)"
: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 "...by some editors—and, even more confusingly..."! Looks more like a hyphen, despite "—” and "–”-users changing hyphens-used-as-dashes to one or other of the dashes to try to differentiate them.)
: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)

: 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.
: 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.
: The above insertion (...insertions... seeming to care about punctuation typos!) I might have left for you to blue-pen out of your own Talk page (whatever the intent behind it) except for my spidey-sense saying it really was ''just'' trolling and that you had no reason to even consider a dismissive reply, never mind argue your defence against such an accusation.

::: Understood, but that'd mean inconveniencing even legitimate readers routing through the same Cloudflare gateways.

I cleaned everything up. You should probably restore the newest 3 topics.

: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).
: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.
: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)

== Complaint transcluded from [[user:ArthurGreenham]] ==
:(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..?)
: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.
: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.
: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.
: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.
: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.
:...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.
: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.
:Instead, perhaps hold back upon feeding the spambots the fresh ground that they seem to like to make use of. Perhaps a page for "please create my userspace!" 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.
: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.
:...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!

:*An internal wiki link is defined like <nowiki>[[2696: Precision vs Accuracy]]</nowiki> 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.
:**If you wanted to internally link with [[2696: Precision vs Accuracy|other text]] then using <nowiki>[[2696: Accuracy and precision|other text]]</nowiki> is the way to do it (use the pipe delimiter).
:*When it comes to wikipedia links, though, we have a nice template for it. By using <nowiki>Accuracy and precision}}</nowiki> (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 "A" and it will still link (usually... always good to check) and linking to something like a w|noun}} can generally be written as <nowiki>|noun}}s</nowiki> 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.

:Ban 162.158.107.56 and 172.71.150.83, they seem to be the perpetuators. [[User:Starstar|Starstar]] ([[User talk:Starstar|talk]]) 02:15, 19 November 2022 (UTC)

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]]

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)

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.

The accounts involved seem to be these;
* CobsonTheGemson
* ChuddyCobson
* Cobson
* Stinkycobbypoopoo
* Chud
* GotTheJakkyDoe

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.

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.

I left the above weirdness since I don't know the etiquette for deleting stuff in this section and it would remove some context to the above person's post. Hope I didn't break anything while cleaning up. [[User:Neerti|Neerti]] ([[User talk:Neerti|talk]]) 10:24, 22 December 2022 (UTC)

== Current troll(s) ==
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]])
: It's been like this forever. It's rare enough that the admins leave things fairly open, but lengthy stretches lead to the lockdowns you're asking for, usually for about a week which is usually sufficient. Mixed feelings. There are a lot of tools that could help a lot, but we can't get [[User:Jeff]] to upgrade because his hosting deal depends on some ad stuff that won't port to newer versions. :( [[User:Liv2splain|Liv2splain]] ([[User talk:Liv2splain|talk]]) 04:45, 22 December 2022 (UTC)

::: I find it unfortunate that "rarity" 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. ([[User:bkayes|bkayes]]) 04:17, 23 December 2022 (UTC)

Actually, looking at [https://www.explainxkcd.com/wiki/index.php?title=Special:Log/newusers&limit=500&type=newusers&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)
: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 "new user early posts" precautionary checks do a very good job.
: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 ("Hi, I see your website needs improving - Eric"-types of message), which also seem to be handled by the community (and/or our automated blocking/reverting).
: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.
: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 ==

The latest comic page (2805) is currently being vandalized. Can an admin please look into it?

== Problem with new accounts and IPs ==

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)
: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.
: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.
: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).
: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. ==

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.
A few people have been valiantly fighting back but that doesn't mean this isn't a problem.
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)

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)

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)

: 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)

== Becoming an admin? ==

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).

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)

: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.

: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.
:(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 "the number of edits" or "the net amount of added bytes"/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..!)
: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.

== "Interesting" Account Creations ==

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 <Semi-generic first name> <semi-generic last name> <usally two or three numbers>. 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.

: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.
: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).
:Amongst the current bunch randomly created names, I see a few that are clearly created around the word "Ingredients" (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.

I tried to sign in to make a small edit to #2954, but I can't create an account with my standard user name "Rosuav" due to one already existing; yet there's apparently no email address on file for that username.

:My instinct is that it could be done, but won't be.

:::Think about it, there's potentially a completely separate existing 'owner' of the contentious username. There's no pre-existing presumption that "<n> years of idleness" ever makes an identity forfeit, certainly not explicitly stated. Unlike various other login-mediated services, there's no real 'private space' to argue over ownership (and legitimate access) for, which saves some problems but then renders moot various possible reasons for making exceptional admin-changes.
:::For any purpose that mattersz it doesn't matter if you sign up as <code>JoeBloggs</code> or <code>Joe Bloggs</code> or <code>The Real Joe Bloggs</code> or <code>JoeyBloggs2008</code> or <code>JB003½</code> or <code>The Name's Bloggs, Joe Bloggs. Licenced To Kill, And Drive A Heavy Goods Vehicle</code>. Look at the [[Special:Log/newusers]], and see how meaningless any given username is, and not worth directly contesting in this sort of circumstance.
:::This is just my observation. I'd defer to any actual Admin who might have a more refined opinion (possibly quite different), Or actual community decisions, by ''named users'', that firmly suggested otherwise.

:Also CG accounts have a nasty habit of reverting an error recently added by (usually) an IP, and, if they can't find enough actual useful typos to correct (the spate of searching for rogue "the the"s was actually mostly useful and correct, but didn't take enough care about it). Also, CGs tend to revert any things that even ''suggest the CGs are linked'' as if to try to erase that idea from everyone's memory, rather than laugh it off or ignore it or say "yeah, and..? ...your problem is?" and I rather expect that this comment will get the same treatment.

2959: Beam of Light

2024-07-18T07:56:57Z

| imagesize = 235x419px

}}

==Explanation==
{{incomplete|Created by a BOT FLYING ALONGSIDE A BEAM OF LIGHT NYYOOOOOOOOOOM - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
{{w|Albert Einstein}} is famous for his theory of {{w|special relativity}} (which deals with the interactions between high speeds and the perceptions of time), and he developed this theory, in part, by imagining himself flying alongside a beam of light. {{w|thought_experiment|Thought experiments}} such as this can reveal what appear to be fundamental principles of the universe that can revolutionize scientific understanding.

In this comic, Einstein is depicted having his very first thought experiment about turning into a beam of light. Comic Einstein is at the early stages of theory development, so his thought experiment is less about breaking down the complex nature of relativity and more about how fun it would be to go really fast. So his thought experiment is currently just, so to speak, a flight of fantasy. (Although even Einstein's "NYYOOOM" sound of a car whizzing by is the sound of the {{w|Doppler effect}}, which alludes strongly to the {{w|Relativistic Doppler effect}}.)

In a similar vein, the title text refers to one of the long-standing issues about Mercury: {{w|Tests_of_general_relativity#Perihelion_precession_of_Mercury|its orbit around the Sun}} doesn't ''quite'' match what {{w|Newtonian physics}} would predict. We now know that this is accounted for by {{w|general relativity}}, another of Einstein's notable theories (which relates how gravity, or the space-time curvature that we understand as gravity, influences time and space, including planetary orbits). Again, we find ourselves overhearing his thoughts before he reaches any insights that will start to explain this. Instead he is stuck at just 'imagining' that Mercury is hot due to its proximity to the Sun, which isn't a particularly novel or useful conclusion, or close to what we would now recognize as Einstein's much-lauded theory.

At around the time of the comic's scenario, being only the first stages of Einstein's thoughts about Relativity, the issue of the Sun's heat was still considered a mystery. The {{w|Kelvin–Helmholtz mechanism}} was proposed as the cause of the Sun's heat but was later superseded by the more modern understanding of nuclear fusion. The {{w|Yarkovsky effect}} had also been previously described as how thermal effects may influence orbital dynamics; this is still useful to know about in the case of asteroids but is not considered a significant factor for Mercury. Neither of these things were ever the focus of Einstein's own studies, though in 1915 he showed that General Relativity could explain Mercury's anomalies and independent observations during a 1919 solar eclipse helped confirm the principles and make Einstein famous.

An older version of Einstein was previously drawn in [[1206: Einstein]] and [[1233: Relativity]].

2957: A Crossword Puzzle

{{incomplete|Do NOT delete this tag too soon.}}

{{notice|<big>'''SPOILER ALERT!'''</big> If you read on without trying to look at the crossword clues first, the joke is spoiled and your chance of finding out the joke yourself is gone instantly!|image=warning!!.png}}

This is a crossword puzzle. On a surface level, the answers seem extremely difficult, with questions covering a wide variety of trivia, linguistics, mathematics in various forms, alongside wordplay typical of crossword puzzles. But the joke is that every single letter of every single answer is "A". See explanation for all 51 clues in the [[#Table|table]] below. All the black squares are in a symmetrical pattern, which is generally the case for crossword puzzles in the US and UK. See description of the pattern in the [[#Transcript|transcript]].

The name of this comic, “A Crossword Puzzle”, is a double entendre; the “A” can be interpreted both as the indefinite article “a”, and as an identifier saying that this crossword puzzle is specifically an “A” puzzle, due to the answer being all “a”s.

The title text is a play on a "type A" personality. The term for someone with a competitive and high-achieving personality is "Type A". In the context of the title text, this answer is a hint that the entire puzzle can be completed in a crossword-solving app by typing the letter A repeatedly.

[[Randall]] pays tribute to a similar comic in the header text of this comic. See the [[#Trivia|trivia]] section below. In that trivia section there is also a picture of the solved puzzle.

| 11-Across || {{w|IPv6}} address record || An IPv4 record is an "A" record; an IPv6 record is four times the length and is designated an "AAAA" record. || 4
|-
| 15-Across || “CIPHERTEXT” decrypted with Vigenère key “CIPHERTEXT” || A "{{w|Vigenère Cipher}}" translates the original text by the distance from A from the key, letter by letter. For instance, if the plaintext is "XK" and the key is "CD", the C shifts X 2 forward to become Z, and the D shifts K 3 forward to become N, yielding a ciphertext of "ZN". Since the ciphertext and the key are the same in this case, decryption just shifts all the letters back to A, akin to subtracting a number from itself and getting 0. || 10
|-
| 16-Across || 8mm diameter battery || An {{w|AAAA battery}} is a 1.5V battery that measures 8.3 mm in diameter, 2.2 mm smaller than the more common AAA battery. || 4

Following the example of the pattern in the clue, taking the first letter and every third one after (rather than just every third letter) we determine that '''A'''ph'''a'''nt'''a'''si'''a''' gives us the word "aaaa". This clue is particularly mean because of how it instructs you to visualize the letters highlighted within the word in order to get the answer. || 4
|-
| 19-Across || An {{w|acrostic}} hidden on the first page of the dictionary || The first page of the dictionary (if you ignore the copyright page and the index) is the list of words starting with A. An acrostic of this page, taking the first letter of each line and arranging them in order, would just be a sequence of A's. || 10

At 210x297 mm, it is approximately 0.24" narrower and 0.71" longer than the 8.5"x11" paper used in the United States, and due to having an aspect ratio of 1:sqrt(2), can be cut in half to create two half-sized sheets with exactly the same aspect ratio. || 4
|-
| 22-Across || First four unary strings || A unary number system represents numbers using just one symbol. E.g. 32 in unary would be 11111111111111111111111111111111. The first four strings in unary, if you used A as the first (and only) symbol, would be A, AA, AAA, AAAA. || 10

|-
| 27-Across || A pair of small remote batteries, when inserted || Two {{w|AAA_battery|AAA}} batteries, which are often used to power remote controls for domestic devices. These have been combined to give AAAAAA — "Inserted" is often a cryptic hint that one word should surround another. || 6
|-
| 29-Across || Unofficial Howard Dean slogan || A reference to Howard Dean, an American Democrat who ran for the party's nomination in 2004.

|-

The scream could be transcribed as "AAAAAAAAAAA" || 10
|-
| 1-Down || Game featuring “a reckless disregard for gravity” || {{w|AaAaAA!!! – A Reckless Disregard for Gravity}} - notably the title is commonly extended in promotional material beyond 6 A's. || 6
|-
| 2-Down || 1010101010101010101010102→16 || 10101010 10101010 10101010 in binary is equivalent to "AAAAAA" in hexadecimal. || 6
|-
| 3-Down || Google phone released July ’22 || The {{w|Pixel 6a}} was released in July 22. Stylized in this puzzle as "AAAAAA" ('A'*6) || 6
|-
| 4-Down || It’s five times better than that ''other'' steak sauce || 5 times better than {{w|A1 steak sauce}} would be A5, stylized in this puzzle as "AAAAA". || 5
|-
| 5-Down || ToHex(43690) || The decimal number 43690 converted to hexadecimal is AAAA. || 4
|-
| 6-Down || Freddie Mercury lyric from ''Under Pressure'' || A drawn-out 'Aaaaahhhh' rising in pitch. || 15
|-
| 7-Down || Full-size Audi luxury sedan || Second of three Audi references. As mentioned previously, the A8 is their full-size luxury sedan. || 8
|-
| 8-Down || Fast path through a multiple choice marketing survey || The "fast path" is just to select the first option over and over again. Usually the options are labeled A, B, C, and D (or more) - choosing the first option for every question would be answering entirely with A's. || 7
|-
| 9-Down || 12356631 in base 26 || Randall is expressing base 26 using the letters of the alphabet with 1=A, in which case 1235663110 = AAAAAA26. (It's unclear how one would express the digit 026 this way.) || 6
|-
| 10-Down || Viral Jimmy Barnes chorus || A reference to the music video for Kirin J Callinan's song '{{w|Big Enough}}', which features Jimmy Barnes in a cowboy hat screaming "Aaaaaaaaaaaaaaa!" while in the sky over mountain scenes. || 15
|-
| 11-Down || Ruby Rhod catchphrase || Ruby Rhod is a radio host in the film '{{w|The Fifth Element}}'; he has a scene with a memorable scream. || 5
|-
| 12-Down || badbeef + 9efcebbb || In hexadecimal, badbeef and 9efcebbb add together to equal AAAAAAAA (195,935,983, 2,667,375,547, and 2,863,311,530 in decimal respectively). || 8
|-
| 13-Down || In Wet Leg’s ''Ur Mum'', what the singer has been practicing || In the song "{{w|Ur Mum}}" by Wet Leg, the bridge starts with "Okay, I've been practicing my longest and loudest scream", which is apparently eight As long. || 8
|-
| 14-Down || Refrain from Nora Reed bot || The "Endless Scream" bot on social media, made by Nora Reed, posts "AAAAAAAAAAA" (with or without an h) at varying lengths. || 8
|-
| 20-Down || Mario button presses to ascend Minas Tirith’s walls || {{w|Minas Tirith}}. In Mario games you typically use the A button to jump. In games where you don't press a button to move (e.g. games with a joystick) then the button presses required to ascend a vertical structure would probably all be A. This clue might have been inspired by the {{w|A-button challenge}} / [https://ukikipedia.net/wiki/A_Button_Challenge A Button Challenge], which tallies the amount of A presses needed to beat ''Super Mario 64''. Additionally, Minas Tirith is a city with seven concentric rings, each with a wall around it and higher than the last ring. Presumably, it takes seven jumps to get to the highest area of the city, so the answer is "AAAAAAA". || 7
|-
| 24-Down || Vermont historic route north from Bennington || {{w|Vermont Route 7A}}, or AAAAAAA. || 7
|-
| 26-Down || High-budget video game || A high budget video game is usually referred to as a Triple-A game, or AAA. || 3
|-
| 28-Down || Unorthodox Tic-Tac-Toe win || Tic-Tac-Toe is usually won by getting either three Xs or three Os in a row, making XXX and OOO normal Tic-Tac-Toe wins. One could achieve a win of AAA by making the unorthodox choice of playing with the letter A instead of X or O. Alternatively, Randall is envisaging the grid as defined by rows 1, 2, 3, and columns A, B, C, so an AAA win would be simply playing in the first column each time - a strategy which should be obvious and easy to stop, even for young children who have not yet worked out that ''any'' route to winning can be blocked. || 3
|-
| 29-Down || String whose SHA-256 hash ends “…689510285e212385” || <code>printf AAAAAAAA <nowiki>|</nowiki> sha256sum</code> outputs <code>c34ab6abb7b2bb595bc25c3b388c872fd1d575819a8f55cc689510285e212385</code>.
Note that this 'clue' would be normally be ''particularly'' difficult, in isolation, as the nature of a {{w|hash function}} means that it is possible for multiple inputs to produce a given output, and that finding any of these (and definitely identifying ''all'' of them, to ensure you have the correct original) would require a {{w|brute-force attack}}; i.e. a test of all possible initial states to discover which of them might be viable candidates. Even more problematic is that we are only given a partial hash string, meaning we are possibly talking of a multiple of full hashes, each of them with a possible multiplicity of original plaintexts behind them.
 The number of possible hashes in the clue is 1664/1616, i.e. 1648, or approximately 6x1054, although there really is no reason (aside from the fundemental impracticality) to try to solve this problem from each and every 'hash end'. Instead you would 'only' check every combination of 8 letters (presuming no digits, punctuation or whitespace would be inserted, that no 'foreign'/accented characters are present and that uppercase is universally presumed, is 268; i.e. ~208 {{w|billion|short-scale billion}} possibilities) and discover which (one?) of these sufficiently matches the hash fragment given. Testing a hundred of these every second, it would take a little over 66 ''years'' to complete the task of checking every single possibility (rather than stopping at the first confirmed answer, which might well be the initial one in this particular case).
 In the context of a crossword such as this, however, you can significantly reduce this search by having established (or at least sufficiently narrowed down) the answers to the various across-clues which intersect with ever character of it (this form of crossword grid being of the {{w|Crossword#American-style crosswords|dense type}}, with no singly-clued spaces as with the more open lattice-types), reducing the necessary checks drastically. This could mean, having solved at least some of the perpendicular answers, that you have enough information to 'guess' at some likely answer, and then merely need to ''confirm'' that whatever guess(es) you make will resolve themselves into the clue-answer provided. (Much as you might with a more normally difficult clue, where you merely have to satisfy yourself that the surprise answer is at least justified as resulting from the original hint.)

==Trivia==
*This comic got a [[Header_text#A_Crossword_Puzzle|comic-specific header text]] after the first day it was up.
**This was because one of the comics Randall lists as one of those he enjoys, [https://www.buttersafe.com/ Buttersafe], had already posted a similar comic back in 2011: [https://www.buttersafe.com/2011/02/17/crosswords/ Crosswords].
**Randall had forgotten this, but now pays tribute to this, stating that he must have been accidentally inspired by that comic.

2955: Pole Vault

2024-07-08T10:48:39Z

172.70.163.121: /* Explanation */ Keeping tenses straight

{{comic
| number = 2955
| date = July 5, 2024
| title = Pole Vault
| image = pole_vault_2x.png
| imagesize = 740x179px
| noexpand = true
| titletext = Ugh, and we JUST went through this yesterday with javelin.
}}

==Explanation==
{{incomplete|Created by a LONG POKEY STICK - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
In the comic, [[Cueball]] is making a run as part of a {{w|pole vault}} competition. However, the pole pierces the surface of the Earth, causing it to pop and violently deflate like a balloon.

This does not normally happen during a pole vault,{{Citation needed}} but the title text suggests that the same recently happened during a {{w|Javelin throw|javelin}} competition, presumably when one of the spears pierced the surface in a similar manner to Cueball's pole. No explanation is provided for how the Earth was patched or re-inflated, but apparently the problem was solved in a single day, without needing to cancel the event, suggesting that this is a normal occurrence.

The comic ''may'' be inspired by the upcoming {{w|2024 Summer Olympics|Paris Olympics}}, and the geographical location of the burst is indeed somewhere in the European continent. The view of the ragged and deflating Earth suggests the possible epicenter of the burst has more of a vague relationship with that area than it might to [[Randall|Randall's]] own location in the US (the other 'logical' definite setting he might use). The comic precedes any of the actual official competitions (or indeed the official Opening Ceremony) by three weeks, but perhaps this event (and the javelin one) occurred at one or other of the attending nations' training camps, or national trials for a local athletics squad, already established in the general region. Alternatively, this is simply depicting future events.

Three comics before this one Randall released [[2952: Routine Maintenance]], where the Earth is being subject to a routine maintenance by pushing the tip of a high pressure canister into Earth and blowing air into Earth to expel debris from inside Earth's volcanoes. That idea seems to be similar, but opposite to the one from this comic. With so few days between the releases there might have been some similar thoughts behind the creation of both.

Talk:2953: Alien Theories

2024-07-02T12:37:20Z

172.70.163.121: /* The 5 Observables */

I understood this differently. I think the UFOs have come to Earth to investigate our conspiracy theories about UFOs with capabilities far beyond what the "real" UFOs posses. [[User:Baruch|Baruch]] ([[User talk:Baruch|talk]]) 07:43, 2 July 2024 (UTC)

== Absence of evidence is not evidence of absence ==
A skeptical human would '''not''' confront UFO believers with evidence that aliens do not exist. They would confront them with the fact that none of the supposed evidence so far has held water, making (extraterrestrial) UFO's not more likely to be real than any other random fantasy. Quite a different matter, since there's rarely verifiable evidence of things '''not''' existing. [[Special:Contributions/172.71.90.9|172.71.90.9]] 08:27, 2 July 2024 (UTC)

==The 5 Observables==
Nowadays, the believers' gold standard for <s>UFOs</s> UAPs is this:
{{quote|There are five, consistent observations we continue to see that are uniquely associated with Unidentified Aerial Phenomena or UAPs. Understanding these characteristics and their application requires us to have a very good understanding of advanced physics at the quantum level.

''The five observables can be categorized as follows:

# Hypersonic velocities without signatures
# Low observability
# Trans-medium travel
# Positive lift
|TTSA|https://tothestars.media/de-de/blogs/press-and-news/five-characteristics-unique-to-uaps}}
Basically, if it seems to break physics, it's a UFO. Aliens who got here using established physics would naturally be curious about that. [[Special:Contributions/172.70.243.214|172.70.243.214]] 10:14, 2 July 2024 (UTC)
:It must be said that a given 'observation' could convey all the above by: 1) Camera wobble, 2) Camera panning, 3) Optical artefacts, 4) Scale/distance misunderstanding, w.r.t the background/foreground features, 5) Subsequent unfounded assumptions about trajectory.
:Which is not to say that it's all bad camera use/interpretation of playback. Radar might be involved (with the possibility of radio-mirages) or even a combination of Mk1 Eyeball and electronic recordings which rule out some 'trivial' counter-explanations. But extraordinary claims need extraordinary evidence, and it would be silly to let something perhaps as simple as camera-shake from a moving vehicle suggest that we need to probe quantum physics for operational loopholes.
:It is at least as bad to "want to believe" as it is to want to ''disbelieve''. And while many such cases may share the same basic anomolies, that make it look like some things are consistently anomolous, this doesn't mean that each case is ''identically'' anomolous. If a bright light disappears, in one case it might be because it's no longer reflecting off the background, in another that the (mundane) source is now shaded by a cloud, in a other it's because the camera lens is no longer subjected to flare, or the video compression artefact is no longer generated, or the observer who verbally reported it no longer has it in the corner of their eye/mentally extrapolated as part of their central blind-spot.
:There's undoubtedly a lot of interesting unknown (so far!) stuff out there, to be witnessed. But lumping in ball lightning, in one instance, with the Sun momentsrily gleaming off the crest of a wave in another, with a perfectly legitimate isolated doorbell-/windshield-cam shot of a meteor in another should not result in an assumption of "bright flash == alien spaceship" as explanation all round.
:If aliens are as super-advanced, technically, as many believe, is there any reason to assume that they even need to leave such teasing evidence of their existence? If you can already twist quantum physics around your little-pseudopod, at will, isn't it more likely that you're already getting past mere human/earthtech monitoring of the skies entirely unseen and ''none'' of the UFO-'sightings' are of you.

==Cueball is an alien?==
A previous edit suggested that Cueball is an alien. Is this canon or a conspiracy theory? [[Special:Contributions/172.70.243.213|172.70.243.213]] 10:26, 2 July 2024 (UTC)
:I did not see this prior form of edit, but I did nearly add my own (conspiracy-)theory that:
:*The aliens are seeing the traces of (vastly more superior) other-aliens around Earth,
:*Said other-aliens are ''only'' leaving significant traces here, not on the original aliens' world/other places they visit,
:*The other-aliens are therefore keen to stay out of observation from the non-other aliens,
:*Or at least generate enough deniability (similar to these aliens being sufficiently deniable to any regular human) so that those who ''are'' convinced get described as 'quack-UFOlogists',
:*Obviously,{{Actual citation needed}} a useful tool in this disinformation war would be to have a human(-looking) representative trying to out-argue the (actually correct, but logically tenuous) alien speculations with diversionary tactics and misdirection.
:Thus Cueball is trying to get the visible aliens to abandon their beliefs in the non-visible aliens by making them think that "anything alien" is ''them'' (those present), and ignore the signs of any subsequent 'visitation'.
:(Note though, that given the prior prediliction for the saucer-people to irrationally believe in Bigfoot, beyond even their own level of ubiquitous monitoring, what we probably have here is Cueball being 'the only sane being in the room'. Unusually, for Cueball. Or at least the san''est'', versus a particularly non-sane other. And standing under an open sky, of course.)

2952: Routine Maintenance

2024-07-02T08:45:01Z

172.70.163.121: /* Explanation */

{{comic

| title = Routine Maintenance

| imagesize = 299x413px

| titletext = The worst was the time they accidentally held the can upside down and froze all the Earth's magma chambers solid.
}}

==Explanation==
{{incomplete|Created by an ONCOMING LETHAL DUST CLOUD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

A recommended routine maintenance step for many electronics, such as desktop computer towers, is to remove the buildup of dust on a regular basis. This can help prevent the electrical components from overheating, and lengthen the lifetime of these electronics. To make this job easier, safer, and cleaner, there exist {{w|Gas duster|cans}} of high-pressure gas, as depicted, which force through high-flow gas to displace the dust. (Attempting to do this with air from the lungs would be less effective, may add unintended moisture to the electronics, and could result in a faceful of dust).

The comic suggests that a similar maintenance step is performed on the Earth itself, blowing gas into the Earth to force out the dust from its magma chambers. However, filling the atmosphere with dust would be unhealthy and fatal to living beings, so as a safety measure everyone would have to take shelter.

This may be a reference to one theory about the K-T extinction event — that a crashing meteor sent so much dust into the air that it killed off many plants and animals, including all non-avian dinosaurs, in a much wider area than that directly affected by the initial impact. Those lineages that chanced to survive the global effects must have been able to escape the worst of the disrupted ecosphere while the worst of the atmospheric effects subsided, and were then able to exploit various newly vacant (and/or changed) environmental niches. (This would include our own mammalian ancestors, and the avian dinosaurs that led to todays birds; some of them may, perhaps, have survived by already being more inclined/suited to living in burrows.) However, this dust cloud would have lasted longer than the 48 hours suggested in the comic.

The image suggests that the "routine maintenance" for Earth would involve using the {{w|Hawaii hotspot}} (possibly via its most active volcano, {{w|Kilauea}}), as the point to insert the high-pressure gas, causing volcanoes to erupt in Iceland, the {{w|Aleutian Islands}} or the {{w|Kamchatka Peninsula}}, the {{w|Andes}}, and elsewhere; the two geographically-indeterminate plumes may represent Italy and Indonesia.

The title text mentions using the can upside-down, and this freezing solid the magma chambers. Pressurised canisters of "air", as with similar aerosol sprayers, contain a propellant gas that condenses into a liquid when compressed. When the spray valve is opened, the release of pressure allows some of the liquid to evaporate and take the place of the released gases, or become some of the gas subsequently released (or all of it, if its purpose is not to spray other contents). The transition of the propellant liquid/gas from dense liquid to space-filling gas requires it to 'boil off', this process needing to pick up {{w|Enthalpy of vaporization|heat (or 'enthalpy') energy}}. Under typical operation, the cooling liquid/gas takes heat from the general mass of the can itself as it tries to attain thermal equilibrium. As a result, the can (and the expelled gases) will be cooled a little. Then (ultimately) heat will also be taken from anything touching or surrounding the slightly cooled can and its spray. This is precisely how a purposeful refrigerant acts, either as a one-time process or as a reversible cycle where repressurising a suitable gas can 'release' heat (the heat/enthalpy of condensation) at the 'hot side' of a refrigerator, returning the gas in the system to liquid that it can later let boil again and cool the 'cold side' of the refrigerator.

It is not normally useful for such a can to allow the liquid propellant-in-waiting to exit the container, as it would waste its usefulness as a source of pressure once it does. But by holding the container the wrong way up (which way that is being dependent upon its design, and intended use...) the pressurised contents push the liquid out via the nozzle's stream. The now exposed propellant is now free to evaporate into the air at atmospheric pressure, typically much lower than the constraints it had within the can, after landing directly upon whatever the can was sprayed at. The resulting demand for heat energy (much more rapid than normal, and likely concentrated upon a much smaller target than the can itself represents) produces a greater localised drop in temperature and can lead to freezing nearby liquids (which may or may not be intended/useful). Of course, the total 'cooling effect' of such a can does not change, depending upon how it is (mis)used, it merely changes the extent (and lifetime) of application, and how extreme the temperature change may be within a much more limited 'liberation' of its cooling ability.

Spraying "canned air" with the can inverted is a party trick used to very quickly cool beverages, being able to bring them down from room temperature to ice cold in seconds if performed correctly.

{{w|Freeze spray|Some spray cans are designed to freeze objects}}, e.g. to help in plumbing repairs or finding overheating electronic components. Freeze spray is also used in medical applications. These require careful use to avoid unintentionally damaging exposed skin or objects that can be damaged by local temperature differences, such as glass.

Given the location of the planetary-scale dust-busting 'air canister', it may be considered confusing which 'way up' is the correct orientation, given that Earth-gravity would be pulling the contents sideways (however that changes what the nozzle ends up ejecting from the can itself). But such a large can would also have its own significant internal 'can-centric' gravity that possibly (depending upon how full of still-liquid propellant it is) exceeds that of the Moon, possibly letting all the denser liquid hold itself into the centre of the canister, even against the nearby Earth's gravity. Being significantly closer to the Earth than the Moon is, this can could also be a far greater influence upon Earth's own tides (not alluded to in the comic), making the dusting of the atmosphere or the freezing of some of its magma secondary issues to the sheltering population. But if magma froze to the extent of disrupting or disabling the {{w|Earth's magnetic field}}, this "secondary" issue could quickly become primary, even existential.

:[The nozzle of a "Dust-Off" (compressed air) gas duster can is pointing into a hole on the Earth's surface in the Pacific Ocean around where Hawaii is located, and its trigger is pressed as an arrow indicates, resulting in dust clouds being released from five visible spots of the Earth. These eruptions can be seen in the Aleutian Islands or Kamchatka Peninsula, Iceland, the Andes, and two further in the eastern hemisphere on the other side of the Earth.]

Talk:2951: Bad Map Projection: Exterior Kansas

2024-06-27T23:51:02Z

172.70.163.121: /* How would the rest of the world look? */

Seems weird that it's just the contiguous US, with "hints" 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)

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)

: 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 "near the center", but rather to the right of the center (in the direction of the "Pacific Ocean" tag). --[[Special:Contributions/162.158.86.100|162.158.86.100]] 05:58, 27 June 2024 (UTC)

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)
: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 "rendered as water", 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)

== How would the rest of the world look? ==

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)
: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.
: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.
:(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.)
: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)

: Check out the Wikipedia article "Azimuthal equidistant projection" and scroll to "Sample azimuthal equidistant projection maps". There is an inverse example, that puts California at the center of a world map. Now imagine everything else in the "great sea" of Randall's map, using a similar projection.

That is, I first used this Antipodes Map [https://www.antipodesmap.com] to locate the point opposite to Lebanon, Kansas at 39°48'35"S, 81°26'39.8"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)

2950: Situation

2024-06-25T08:36:31Z

172.70.163.121: /* Explanation */

{{comic
| number = 2950
| date = June 24, 2024
| title = Situation
| image = situation_2x.png
| imagesize = 578x306px
| noexpand = true

}}

==Explanation==
{{incomplete|Created by a Shark, the iceberg of the sea - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic depicts a situation involving multiple pieces of infrastructure: a ship, sailing towards icebergs, which is tethered to an airship flying next to a power plant towards a bridge. Each of these are labelled with details that clearly reference famous disasters, all of which were caused (at least in part) by design failures. All of these incidents are common case studies for engineers studying how things can go very wrong. The implication is that, by putting them all together, most engineers would be highly concerned with the potential for catastrophe.

- "Unsinkable Ocean Liner" refers to the RMS ''{{w|Titanic}}''.

The ''Titanic'' was a British ocean liner which famously {{w|Sinking of the Titanic|sank}} on its maiden voyage in 1912. It was the largest ship in operation at the time, and was called "unsinkable" due to its size and much-lauded design features. The ship struck an iceberg on the fourth day of its first voyage, breaching the hull and ultimately causing it to sink, resulting in 1,496 deaths. Multiple design inadequacies, including too few life boats and inadequate steering ability, were afterwards identified as contributing to the ship sinking and to the high loss of life.

- "Hydrogen-filled [Airship]" refers to the {{w|Hindenburg Disaster}}.

The {{w|LZ 129 Hindenburg|''Hindenburg''}} was a German airship which used hydrogen as a lifting gas. In 1937, during a landing in New Jersey, the ship caught fire and the inflammable hydrogen quickly ignited, causing the ship to crash and resulting in 36 deaths. While the origins of the fire are still debated, the dangers of using large amounts of inflammable gas in airships were made dramatically clear.

Ironically, the hydrogen airship in the comic appears to have been commissioned for the purpose of mitigating iceberg risks (unless 'iceberg spotting' is for the purpose of steering the 'Unsinkable Ocean Liner' towards icebergs, perhaps as a tourist attraction).

- "Soviet Era Nuclear Reactor Undergoing a Turbine Test" refers to the {{w|Chernobyl Disaster}}.

The {{w|Chernobyl Nuclear Power Plant}} is located near the city of Pripyat, in Ukraine (under the Soviet Union at the time of the disaster). On 26 April 1986, a reactor core partially melted during a turbine test. This led to an explosion, causing a massive release of radiation. This incident remains the worst nuclear accident to date. The number of fatalities from the disaster are difficult to calculate; two people died from the initial damage, twenty-eight more from acute radiation sickness, and fifteen people who were directly exposed developed terminal thyroid cancer. The radiation, however, spread far beyond the plant itself and the number of premature deaths ultimately attributable to subsequent exposure can't be calculated directly, though most estimates are easily in the thousands.

- "Bridge Prone to Aeroelastic Flutter in High Winds" refers to the {{w|Tacoma Narrows Bridge (1940)|Tacoma Narrows Bridge}}.

The Tacoma Narrows Bridge, a suspension bridge in the U.S. state of Washington, was initially built in 1940. From the time of its construction, the bridge was observed to sway and {{w|Aeroelasticity#Flutter|flutter}} in high winds. About four months after opening, the bridge fluttered so violently in 40 mile-per-hour (64 km/h) winds that it collapsed into the strait. There were no human fatalities, though several people were injured. This collapse is frequently used to demonstrate the dangers of harmonic vibration in infrastructure, particularly structures exposed to strong winds. The bridge was eventually rebuilt, with a redesign intended to prevent such fluttering.

As illustrated, it appears that the ship is about to sail under the bridge, while the airship will fly over it, causing the tether between the two to snag the bridge.

- The title text refers to the {{w|Space Shuttle Challenger Disaster}}.

The {{w|Space Shuttle Challenger|''Challenger''}} was an American space shuttle which broke up shortly after its launch in 1986, killing all seven crew members aboard before reaching orbit. The disaster was caused by a failure of O-ring seals on one of the shuttle's rocket boosters and the subsequent leak of hot gasses. The likely cause of these failures was because the weather was much colder than normal in the launch area, causing the seals to be well below their design temperature range in the immediate lead-up to being exposed to launch conditions, and were then unable to maintain their integrity. Engineers for the company that had built the boosters raised this concern and recommended postponing the launch, but were overruled.

2948: Electric vs Gas

}}

==Explanation==
{{incomplete|Created by a HYDROGEN INTERNAL COMBUSTION ENGINE RUNNING A GENERATOR. Do NOT delete this tag too soon.}}

{{w|Internal combustion engine|Internal combustion engines}} (ICEs) have long been the most common technology used to propel motor vehicles. In US vernacular, the most common vehicle fuel is known as "{{w|gasoline}}", or "gas" for short, leading to these engines being referred to as "gas engines". Gasoline is a product of petroleum refinement, leading to the name "petrol" being used in other dialects.

{{w|Traction motor|Electric motors}} would seem the more well-suited method for propelling a vehicle, and as early as 1885 were an actual form of motor car engine with which the fledgling internal combustion engine had to compete. Despite this early popularity, over most of the 20th century electric motors were sidelined in everyday car design, as supplying the electricity was considered to be impractical for most forms of transportation. Modern forms are rapidly rising in popularity, and [https://www.iea.org/reports/global-ev-outlook-2024/trends-in-electric-cars now constitute 18% of all global vehicle sales]. [[Randall]] is a strong proponent of {{w|electric vehicle}}s (EVs).

In this strip, [[White Hat]] claims to be comparing the pros and cons of electric motors and gas engines. The joke is that every point he makes goes in favor of electric motors. Despite it being posed as a dilemma, it may be very clear which side of the debate White Hat is promoting. On the other hand, it may indicate that one of the things we might consider a pro in electric motors (the instantaneous power now available, exceeding that of many non-electric engines) he would consider a problem — perhaps more accurately, a problem with the ''drivers'' of such vehicles — recklessly using the enhanced capabilities to accelerate to high speeds at all opportunities, whether safe to do so or not.

The strip offers the following points in favor of electric motors:

* "Cleaner and more efficient". ICEs produce and vent harmful combustion products and toxic chemicals, while electric motors produce no emission byproducts at the point of use. The efficiency of both gas and electric motors vary, but the typical ICE vehicle in the US converts around 25% of available energy into motion, while the typical electric vehicle is in the neighborhood of 80%. Even when considering inefficiencies in the source production and transmission and storage and release of energy, battery-driven electric vehicles are generally more efficient than internal combustion propelled vehicles[https://www.factcheck.org/2024/02/electric-vehicles-contribute-fewer-emissions-than-gasoline-powered-cars-over-their-lifetimes/]. It should be noted that all of this refers to the motors only, and ignores how the fuel and electricity are produced, or the wider environmental impact of the vehicle.

* "More powerful". Electric motors are able to deliver a lot of power from a small motor ''if'' an ample energy supply is available, and can do so 'on demand', often far quicker than a fuel-powered engine that has to put its power through a gearbox in order to service a wide range of road velocities, from standstill to the eventual top speed. Due to battery limitations, short or partial runtime use cases (such as dragsters, hand tools, yard tools, toys and electric scooters) net the most benefit from the small size of a high-powered electric motor.

* "Annoyingly loud". ICEs, by their nature, produce significant noise. Despite noise attenuation measures such as mufflers, they contribute significantly to urban noise. Properly designed electric motors are nearly silent (even if the rest of the vehicle is not). In particular, {{w|blowoff valve|turbocharger blowoff valves}} make particular noises that are completely lacking in an all-electric vehicle being driven at a similar performance level. This might legitimately be considered a problem, though, when everyone is used to a rapidly approaching vehicle providing a very noisy warning of its approach. EV makers have sometimes added [https://www.businessinsider.com/electric-car-ev-fake-engine-sound-hyundai-dodge-toyota-2023-7 fake ICE noises] to appeal to older drivers, and in the U.S. and some other countries, EVs are required to have {{w|Electric vehicle warning sounds|warning sounds}} at low speeds for pedestrian safety.

* "WAY less {{w|torque}} available at standstill". ICEs need to continually operate within a specific range of rotational speeds, which means that a complex system of {{w|transmission|transmission gearing}} is needed to convert this motion into the specific speeds needed at the wheels. When starting from a standstill, this means that torque must be applied to the wheels relatively gradually to avoid stalling the engine. In addition, when a vehicle is standing still, the motor is typically idling at (very) low speed and must be sped up before it produces significant acceleration. Electric motors, in contrast, generally produce their peak torque when at a standstill. This results in electric vehicles having significantly better acceleration and engine responsiveness. Again, this could cause a legitimate problem with drivers changing from ICE to electric motors, because the new cars accelerate more than the driver is used to and provide different feedback. The audible clues of gear changes, whether from automatic or manual systems, are part and parcel of what many people have grown up with and come to rely on in anticipating what might need paying attention to.

The strip offers no points in favor of internal combustion (gas) motors, even those framed as if they were such.

It should be noted that White Hat is deliberately confining his arguments to electric vs gas ''motors'' rather than electric or gas-powered ''vehicles''. Doing so ignores the basic reason why internal combustion vehicles have long dominated transportation in certain specific countries: hydrocarbon fuels are a very dense and fairly easy to handle form of energy ''storage''. Providing electrical power to a moving vehicle requires either that the vehicle remain in contact with a power line (as with an electric train or a tram) or else to carry a high-capacity battery (and the ability to recharge that battery in a reasonable amount of time, while stationary). More popular in the USA is a hybrid system, where a combustion engine provides at least some of the power to an electric motor, which was impractical until comparatively recently. Other methods, such as hydrogen fuel cells (a form of "combustion" that can be used more directly to form electricity), have been proposed, but remain niche, due to various barriers to adoption, or experimental.

A more comprehensive comparison would include many more factors, both against and in favor of electric cars.

Issues raised with electric vehicles typically include:
* Higher cost of purchase (primarily due to the cost of batteries and, in the USA, now a 100% tariff on Chinese EVs), although partially offset by lower costs of operation
* Long charging times compared to refilling a gas tank (there are some approaches which mitigate this by operating either very high powered chargers or a battery swap model, rather than charging in-car, but these are not widely adopted)
* Relatively limited range ([https://ev-database.org/compare/electric-vehicle-longest-range 100-400 miles per charge] as of 2024)
* Shortened range in hot weather and significantly shortened range in cold weather (although ICE vehicles also have this problem)
* Limited charging infrastructure in some places (although ICE vehicles also have this problem)
* Higher vehicle weight, and resulting higher particulate emissions (from tires, but not brakes, because EVs use of regenerative braking reduces wear on their traditional brakes)
* Reliance on various mineral and metal extraction industries in the building of batteries
* Issues disposing of/recycling batteries at end of life
* Increased demand on electricity production
* At highway speeds, the noise of tires against the road is much louder than a properly muffled ICE, thus electric vehicles become nearly as loud as their ICE vehicle counterparts

Other real (or asserted) pros of electric cars are also not mentioned:
* Lower costs of operation (partially offset by higher costs of purchase)
* Can "fill" them at home or while parked without having to stay with them (partially negates the "long charging times" con)
* Higher reliability
* Lower carbon footprint, and reduced dependence on the fossil fuel industry

Rapidly evolving technologies, government policies, and economic realities are changing the relevance and seriousness of these points over time. As of the publication of this strip, the "pros" of EVs do not seem to be universally convincing, as ICEs remain far more popular than EVs in most countries (EVs constitute a majority of new vehicle sales in only four countries: Norway, Iceland, Sweden and Finland). That said, EVs didn't exist as a viable industry 20 years ago, so the current reality reflects rapid and ongoing growth, suggesting that the perceived advantages of EVs are gaining increasing social currency.

The degree of adoption is also likely to impact the viability of different vehicle types. Infrastructure in most countries has long been built around an assumption of ICEs, so things like fueling stations and ICE-qualified mechanics have traditionally been widely accessible. As EVs becoming increasingly dominant, this could shift, with EV charging infrastructure becoming easier to find than ICE fueling stations, and ICE mechanics potentially becoming more difficult to find. There's typically a certain level of inertia in the adoption of any new technology.

In the EU, [https://www.europarl.europa.eu/topics/en/article/20221019STO44572/eu-ban-on-sale-of-new-petrol-and-diesel-cars-from-2035-explained the sale of new ICE cars is banned from 2035] in an effort to move to EVs, and other jurisdictions are adopting similar policies.

Especially in the United States, this topic is highly contentious for political, economic, engineering, and {{w|Rolling coal|tribal}} reasons (as a quick look at the edit history of this page will confirm).

==Trivia==
The etymology of "gasoline" (commonly abbreviated to "gas") is disputed: it may refer to the gaseous {{w|state of matter}} as, though gasoline itself is generally liquid, it readily emits volatile vapours. Otherwise, it has been suggested to have derived from "Cazelin"/"Cazelline", originally a lamp-oil, sold by a man called {{w|John Cassell}} in the 19th century and much copied (including by the "Gazeline" brand) as the market and supply of such fuels expanded. In non-American english, the octane form of motor-fuel (i.e. non-diesel and excluding aviation fuel) is called "petrol" (derived from "petroleum", or 'oil of the rock'), with similar "electric vs petrol (vs {{w|Hybrid electric vehicle|hybrid}})" comparisons. The registered brand name "Petrol" (sold as a solvent, before being repurposed for use as vehicle fuel) could not be trademarked as it was already the common generic term for equivalent products. The unrefined crude mineral oil from which many different hydrocarbon products can be refined is still more widely known as petroleum. Vehicle fuel may now be partly or wholly composed of non-fossil-fuels to distance them from some of the traditional arguments against petrol/gas consumption, leave other considerations unchanged but possibly introduce {{w|Biofuel#Issues|further issues}}.

While ICE vehicles have, to date, proven more popular than electric equivalents, worldwide, bicycles have been outselling cars [https://www.bikeradar.com/features/bike-vs-car-the-sales-race|since at least WWII].

* "Cleaner and more efficient". ICEs produce and vent harmful combustion products and toxic chemicals, while electric motors produce no emission byproducts at the point of use. The efficiency of both gas and electric motors vary, but the typical ICE vehicle in the US converts around 25% of available energy into motion, while the typical electric vehicle is in the neighborhood of 80%. Even when considering inefficiencies in the source production and transmission and storage and release of energy, battery-driven electric vehicles are generally more efficient than internal combustion propelled vehicles[https://www.factcheck.org/2024/02/electric-vehicles-contribute-fewer-emissions-than-gasoline-powered-cars-over-their-lifetimes/]. It should be noted that all of this refers to the motors only, and ignores how the fuel and electricity are produced, or the wider environmental impact of the vehicle.

* "More powerful". Electric motors are able to deliver a lot of power from a small motor ''if'' an ample energy supply is available, and can do so 'on demand', often far quicker than a fuel-powered engine that has to put its power through a gearbox in order to service a wide range of road velocities, from standstill to the eventual top speed. Due to battery limitations, short or partial runtime use cases (such as dragsters, hand tools, yard tools, toys and electric scooters) net the most benefit from the small size of a high-powered electric motor.

* "Annoyingly loud". ICEs, by their nature, produce significant noise. Despite noise attenuation measures such as mufflers, they contribute significantly to urban noise. Properly designed electric motors are nearly silent (even if the rest of the vehicle is not). In particular, {{w|blowoff valve|turbocharger blowoff valves}} make particular noises that are completely lacking in an all-electric vehicle being driven at a similar performance level. This might legitimately be considered a problem, though, when everyone is used to a rapidly approaching vehicle providing a very noisy warning of its approach. EV makers have sometimes added [https://www.businessinsider.com/electric-car-ev-fake-engine-sound-hyundai-dodge-toyota-2023-7 fake ICE noises] to appeal to older drivers, and in the U.S. and some other countries, EVs are required to have {{w|Electric vehicle warning sounds|warning sounds}} at low speeds for pedestrian safety.

* "WAY less {{w|torque}} available at standstill". ICEs need to continually operate within a specific range of rotational speeds, which means that a complex system of {{w|transmission|transmission gearing}} is needed to convert this motion into the specific speeds needed at the wheels. When starting from a standstill, this means that torque must be applied to the wheels relatively gradually to avoid stalling the engine. In addition, when a vehicle is standing still, the motor is typically idling at (very) low speed and must be sped up before it produces significant acceleration. Electric motors, in contrast, generally produce their peak torque when at a standstill. This results in electric vehicles having significantly better acceleration and engine responsiveness. Again, this could cause a legitimate problem with drivers changing from ICE to electric motors, because the new cars accelerate more than the driver is used to and provide different feedback. The audible clues of gear changes, whether from automatic or manual systems, are part and parcel of what many people have grown up with and come to rely on in anticipating what might need paying attention to.

The strip offers no points in favor of internal combustion (gas) motors, even those framed as if they were such.

It should be noted that White Hat is deliberately confining his arguments to electric vs gas ''motors'' rather than electric or gas-powered ''vehicles''. Doing so ignores the basic reason why internal combustion vehicles have long dominated transportation in certain specific countries: hydrocarbon fuels are a very dense and fairly easy to handle form of energy ''storage''. Providing electrical power to a moving vehicle requires either that the vehicle remain in contact with a power line (as with an electric train or a tram) or else to carry a high-capacity battery (and the ability to recharge that battery in a reasonable amount of time, while stationary). More popular in the USA is a hybrid system, where a combustion engine provides at least some of the power to an electric motor, which was impractical until comparatively recently. Other methods, such as hydrogen fuel cells (a form of "combustion" that can be used more directly to form electricity), have been proposed, but remain niche, due to various barriers to adoption, or experimental.

A more comprehensive comparison would include many more factors, both against and in favor of electric cars.

Issues raised with electric vehicles typically include:
* Higher cost of purchase (primarily due to the cost of batteries and, in the USA, now a 100% tariff on Chinese EVs), although partially offset by lower costs of operation
* Long charging times compared to refilling a gas tank (there are some approaches which mitigate this by operating either very high powered chargers or a battery swap model, rather than charging in-car, but these are not widely adopted)
* Relatively limited range ([https://ev-database.org/compare/electric-vehicle-longest-range 100-400 miles per charge] as of 2024)
* Shortened range in hot weather and significantly shortened range in cold weather (although ICE vehicles also have this problem)
* Limited charging infrastructure in some places (although ICE vehicles also have this problem)
* Higher vehicle weight, and resulting higher particulate emissions (from tires, but not brakes, because EVs use of regenerative braking reduces wear on their traditional brakes)
* Reliance on various mineral and metal extraction industries in the building of batteries
* Issues disposing of/recycling batteries at end of life
* Increased demand on electricity production
* At highway speeds, the noise of tires against the road is much louder than a properly muffled ICE, thus electric vehicles become nearly as loud as their ICE vehicle counterparts

Other real (or asserted) pros of electric cars are also not mentioned:
* Lower costs of operation (partially offset by higher costs of purchase)
* Can "fill" them at home or while parked without having to stay with them (partially negates the "long charging times" con)
* Higher reliability
* Lower carbon footprint, and reduced dependence on the fossil fuel industry

Rapidly evolving technologies, government policies, and economic realities are changing the relevance and seriousness of these points over time. As of the publication of this strip, the "pros" of EVs do not seem to be universally convincing, as ICEs remain far more popular than EVs in most countries (EVs constitute a majority of new vehicle sales in only four countries: Norway, Iceland, Sweden and Finland). That said, EVs didn't exist as a viable industry 20 years ago, so the current reality reflects rapid and ongoing growth, suggesting that the perceived advantages of EVs are gaining increasing social currency.

The degree of adoption is also likely to impact the viability of different vehicle types. Infrastructure in most countries has long been built around an assumption of ICEs, so things like fueling stations and ICE-qualified mechanics have traditionally been widely accessible. As EVs becoming increasingly dominant, this could shift, with EV charging infrastructure becoming easier to find than ICE fueling stations, and ICE mechanics potentially becoming more difficult to find. There's typically a certain level of inertia in the adoption of any new technology.

In the EU, [https://www.europarl.europa.eu/topics/en/article/20221019STO44572/eu-ban-on-sale-of-new-petrol-and-diesel-cars-from-2035-explained the sale of new ICE cars is banned from 2035] in an effort to move to EVs, and other jurisdictions are adopting similar policies.

Especially in the United States, this topic is highly contentious for political, economic, engineering, and {{w|Rolling coal|tribal}} reasons (as a quick look at the edit history of this page will confirm).

==Trivia==
The etymology of "gasoline" is disputed: it may derive from "gas", or perhaps from the brand-name fuel "Cazeline" or "Cazelline" sold by a man called John Cassell; "Petrol" has also been a registered brand name for other businesses' motor-fuel products.

While ICE vehicles have, to date, proven more popular than electric equivalents, worldwide, bicycles have been outselling cars [https://www.bikeradar.com/features/bike-vs-car-the-sales-race|since at least WWII].

2948: Electric vs Gas

2024-06-21T08:17:53Z

}}

==Explanation==
{{incomplete|Created by a HYDROGEN INTERNAL COMBUSTION ENGINE RUNNING A GENERATOR. Do NOT delete this tag too soon.}}

{{w|Internal combustion engine|Internal combustion engines}} (ICEs) are the most common technology used to propel motor vehicles. In US vernacular, the most common motor fuel is known as "{{w|gasoline}}", or "gas" for short, leading to these engines being referred to as "gas engines". Gasoline is a product of petroleum refinement, leading to the name "petrol" being used in other dialects.

{{w|Traction motor|Electric motors}} would seem the more well-suited method for propelling a vehicle, and as early as 1885 were an actual form of motor car engine with which the fledgling internal combustion engine had to compete. Despite this early popularity, over most of the 20th century electric motors were sidelined in everyday car design, as supplying the electricity was considered to be impractical for most forms of transportation. Modern forms are rapidly rising in popularity, and now constitute 18% of all global vehicle sales.{{acn}} [[Randall]] has long been a strong proponent of electric vehicles.

In this strip, [[White Hat]] claims to be comparing the pros and cons of electric motors and gas engines. The joke is that every point he makes goes in favor of electric motors. Despite it being posed as a dilemma, it may be very clear which side of the debate White Hat is promoting. On the other hand, it may indicate that one of the things we might consider a pro in electric motors (the instantaneous power now available, exceeding that of many non-electric engines) he would consider a problem — perhaps more accurately, a problem with the ''drivers'' of such vehicles — recklessly using the enhanced capabilities to accelerate to high speeds at all opportunities, whether safe to do so or not.

* Issues disposing of/recycling batteries at end of life
* Increased demand on electricity production

Advancing technologies, political policies, and economic realities are rapidly changing the relevance and seriousness of these points. The current adoption rate of EVs (well under 50%, even in California) is an indication that the general population thinks the cons still win.

Other real (or asserted) pros of electric cars aren't mentioned, which is still not the point of the comic
* Lower costs of operation (partially offset by higher costs of purchase)
* Can "fill" them at home or while parked without having to stay with them (partially negates the "long charging times" con)
* Higher reliability
* Lower carbon footprint, and reduced dependence on the fossil fuel industry

Future economic and political policies may make fueling and maintenance of gas powered personal cars an issue. If in 10 years 100% of cars sold are electric, then after the average 12 year vehicle lifespan of fuel cars has ended it may be that legacy fuel stations are harder to find (and recharging stations easier) in comparison to the other type. At the 20-year mark, most gasoline-fueled cars will be gone and the economic value of providing ubiquitously available fuel to a dwindling number of cherished hold-out 'classic' vehicles will have forced the supply chains to pivot. Maintenance for such cars may become an art of the past and finding a specialized mechanic may be necessary. (As, until recently, it would have been difficult to find an independent EV-qualified mechanic.)

Talk:2944: Magnet Fishing

2024-06-11T09:07:51Z

172.70.163.121:

Isn't the solution to make the competition like skiing: The participants take turns fishing, instead of all fishing at the same time? And they're judged on how quickly they can "catch" a magnet in the water. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 15:44, 10 June 2024 (UTC)

This comic made me cackle. My cat is hiding under my bed now. [[User:Psychoticpotato|Psychoticpotato]] ([[User talk:Psychoticpotato|talk]]) 21:30, 10 June 2024 (UTC)

== Title text ==

I believe the first "ten-way tie" refers to calling the competition a "tie" between ten competitors. It's more common in British English, but can be used as a synonym for game/match/etc. So it's saying "the ten-person match was judged a ten-way draw". {{unsigned|MightyP|16:36, 10 June 2024}}
: It's a pun on tie meaning to knot/tangle the lines, and tie in the sense of competitors finishing equally. [[Special:Contributions/172.70.134.117|172.70.134.117]] 18:29, 10 June 2024 (UTC)
:As a British Englisher(!) myself, I think "cup tie" (e.g. the final culmination of a knockout competition) tends to be what "breaks the tie" between the ''two'' teams that have each reached this stage equally successful against all other opponents. (Also "3rd/4th-place tie", etc.) You don't tend to get N-way competitions called a 'tie' (though, theoretically, a trifurcated bracketing system could bring 27 teams in nine games teams could become nine teams in three games, then three three teams producing the winner, etc).
:Tie/tangle and tie/equally-scored is going to be good enough. If Randall had thought of the "cup tie"-type usage, he could have easily made a tripled-pun version with that ''and'' the two more obvious versions. [[Special:Contributions/172.70.160.248|172.70.160.248]] 21:30, 10 June 2024 (UTC)

The prize is also a bit of wordplay. It refers to a magnetic monopole as already noted, but is also a joke, as a regular fishing pole is technically a "monopole". I've never personally seen a fishing dipole, but I suppose they could exist! {{unsigned|MightyP|16:49, 10 June 2024}}

== Triple pun for some speakers ==

I found it funny that in Austrian, monopole is "Monopol", and we use the same word for monopole and monopoly!
The prize also feels special if you have a monopoly on magnet fishing - without all the others interfering with your magnet like in the comic.

First time ever posting here. Keep up the good spirit! [[Special:Contributions/172.68.50.13|172.68.50.13]] 20:45, 10 June 2024 (UTC)

== Monopoles ==

If you did have a magnetic monopole... Would the field lines look a lot like the strings in this comic?

: It could in the Arctic ocean with a south monopole! Near the monopole the field lines point inward but far away they point in the direction of Earth's field. There are parts of the Arctic ocean with a 90 degree inclination and the lines are vertical instead of north-to-south. Monopoles also have two advantages: The field drops off inverse-square instead of of inverse-cube, giving the "hook" a longer range. Also, if all contestants have the same kind of monopole they will repel instead of sticking to each-other.

: [[Special:Contributions/172.70.80.121|172.70.80.121]] 00:17, 11 June 2024 (UTC)

:: If the contestans' monopoles repelled each other, things could get pretty chaotic with so many of them in close proximity. None of the monopoles would be in a stable position, so the fishing lines would tangle up even worse than if they were all dipoles attracted to each other.

The magnetic field lines coming out of a magnetic monopole look very much like the fishing lines coming away from the magnets all stuck together in the comic. The first thing I thought when I saw the title and the picture was that Randell was drawing a magnetic monopole.

I've noticed that this doesn't seem to be the case in all languages. For example, when native Polish speakers talk rapidly (even when speaking English), they enunciate every sound accurately in quick succession while flattening out the tone and rhythm of their speech. I wonder if this is because Polish is an inflected language where the grammar of the sentence is determined by endings of words rather than word order.

:(Edit conflicted with 162, above, so this is my own reply...) I thought it was that it isn't "ho T'p otato", with the "teh-peh" awkwardness. For me, the natural way to say it is to glottalstop the first T for more "ho'potato" (the other Ts, there I find awkward ''not'' to get the "t>s<" out of, the ">s<"-tail being what makes a full-T not a lazy one). But clearly a different accent involved, as "ha" doesn't work at all for me unless I try to use some sort of (probably awful) Goodfellas-type accent. And my native accent is notoriously good at glottlestopped Ts (that most people misinpersonate badly, by attaching them to the wrong adjacent syllable).
:As for "going to", experimentally holding my finger over the length of my tongue, it seems it barely has to move at all in "going" (the whole tongue wants to rise on the "i", but I can suppress that and do the tone-change from further back, if not straight from the vocal chords). Though continuing through to the "to", with my finger in there, it's no better than "going ku" as I prevent the tongue-tip doing the necessary small movement to fulfil any form of T. I can do better through basic gastromancy, but behind my unmoving jaw and lips (''without'' the finger almost down my throat, of course), I can feel the tongue tip doing it's small but vital "crossing the T" work.

==Explanation==
{{incomplete|Created by a Transportationally convenient but insidiously dangerous robotic car - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

Randall's chart compares different modes of transportation by how convenient and dangerous they are. At the top-left (high in convenience and low in danger) are airliners and trains, as these are both fast-moving vehicles on which many millions of dollars have been spent to make them safer. In the top-right, motorcycles are at the same convenience level, but are rated much more dangerous, since they are easy to lose control of at high speeds, and careless drivers (of cars) can easily hit a motorcycle and cause extreme harm. Things like unicycles (bottom-left) are considered much lower on the convenience scale, being not very fast or easy ways to travel, but relatively safe, while towards the centre, skis are apparently moderately convenient and moderately dangerous, since they are relatively easy to fall on if going fast downhill. Way out on their own in the bottom-right, hot air balloons appear to be unique in being rated least on convenience and highest on danger.

Because a hot air balloon is rated so poorly, if an optimization algorithm considers it the optimal mode of transportation, it must be the result of a sign error (e.g. having a minus sign where a plus sign is supposed to be, or vice versa), making the algorithm optimize for the opposite result by mistake. Presumably, modes of transportation similar to hot air balloons (like zeppelins and blimps) are left off the chart to increase the gap for comedic effect.

In order to compare the relative danger from each mode of transport, one can look at statistics of fatalities and injuries sustained during each activity. Traditionally this can be reported in fatalities/{{w|Killed_or_Seriously_Injured|KSI}} per mile driven or passenger mile (or other unit of distance), to account for the fact that some modes are used much more than others and make valid comparisons. They may also be reported per capita (but this ignores the relative usage of different modes), or per journey (but this doesn't take into account the fact that different modes typically have different journey lengths and times). All of these are somewhat flawed, since they are really measuring the danger ''to'' users of that mode of transport, both from their own conveyance, and from other sources such as other road users. Since ballooning is not a very common mode of transport, hot air balloon incidents are [https://pubmed.ncbi.nlm.nih.gov/9533500/ correspondingly uncommon], and flights are not routinely monitored or registered, it is difficult to draw strong conclusions from the data for hot air balloons.

The title text makes a joke that if a hot air balloon enthusiast disagrees with the ranking and is angered by it, they may wish to remonstrate or retaliate, but will have a difficult time getting to Randall's house with their preferred mode of transportation, because they are limited to travelling in the direction of the wind. If they chose an alternative form of transport, they would be making his point for him. In reality, hot air balloons have some freedom to choose their direction of travel, since by controlling their altitude they can access different wind directions at different heights. Randall should, therefore, be concerned about hot air balloonists who live within a wedge spanned by the various wind directions accessible on a given day. In principle, if the weather conditions are favorable, this could cover every direction from Randall's house. The phrase "hot air balloon people" is reminiscent of "autogyro people" from the title text of [[1972: Autogyros]].

Curiously, the comic includes most common forms of transport, and a number of less common ones, but omits examples such as buses (a mass transit solution arguably more convenient than trains). It is not clear if this is an error, or a deliberate choice to maintain the comic's layout and presentation.

This is the second comic in a row to feature an algorithm.

Talk:2940: Modes of Transportation

172.70.163.121:

I'd say a bicycle is way less dangerous than a car [[Special:Contributions/172.68.192.196|172.68.192.196]] 21:36, 31 May 2024 (UTC) (para 1/4)
:Considering only the two vehicles themselves, I would probably agree with you but this comic is about convenience and danger of various means of transport. Wouldn't you agree that using a bicycle for transport in crowded city traffic is rather more dangerous to the cyclist than using a car is to the driver? {{unsigned ip|172.69.60.138|21:46, 31 May 2024}}
:It depends on whether you're comparing worst case injuries versus injury rate. Since airliners are considered one of the safest, I think it's injury rate. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 22:07, 31 May 2024 (UTC)
:I'd say a bicycle is less dangerous than a unicycle, but apparently walking<unicycle<car<bicycle. No metric I can think of matches that order, neither danger in a vacuum, danger in a self-environment, danger in a car environment, or danger to others in any environment. I'm quite confused. --[[Special:Contributions/172.70.114.29|172.70.114.29]] 05:29, 1 June 2024 (UTC)
::On a per-passenger-mile basis, walking is over ten times more dangerous than driving, and trains are about four times as dangerous as planes. So this comic can't be about risk of death per mile. It must be something more like risk of death per hour, which is extremely low for unicycles since people don't usually ride them in life-threatening situations outside of circuses. Similarly, travelling to and from work on a pogo stick every day would be quite dangerous, but in practice, people hardly ever die on a pogo stick. So it depends how you measure it. [[User:EebstertheGreat|EebstertheGreat]] ([[User talk:EebstertheGreat|talk]]) 06:07, 1 June 2024 (UTC)
::: I can see the danger/hour, but surely the unicycle shouldn't count as a mode of transportation when it is used in a circus? You also don't want to count the hours when a car is stationary and the driver is waiting for someone to enter or leave (which is a significant amount of time for taxi's). So when it is used for actual transportation, it is most certainly more dangerous per hour than many other things on this graph. --[[Special:Contributions/172.70.110.99|172.70.110.99]] 23:58, 1 June 2024 (UTC)
:I think there is a couple that are off on here since I think light aircraft and helicopters are also less dangerous than cars when looking at accident rates vs trips or vs miles traveled. Cars are quite dangerous. They sure are convenient though. [[Special:Contributions/172.64.238.87|172.64.238.87]] 09:57, 1 June 2024 (UTC)
:Agreed: By any metric I can think of, this chart is grossly off on more than one form of transport. For one thing, inline skating is ''much'' safer than skateboarding in almost every scenario except approaching a bunch of mean kids. [[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 21:59, 2 June 2024 (UTC)
: I think the metric he's using is actually ''perceived'' danger.[[Special:Contributions/172.70.90.145|172.70.90.145]] 08:19, 3 June 2024 (UTC)
:: I think the whole chart is on a "perceived" level. I would assume that "convenience" also would include "getting from A to B fast" for which cars and bicylces are too close together. And motorcycles are surely fun but if they were even closely as convenient as a car I would use the former more often than latter - which I don't as a car is MUCH more convenient. I think the meaningfulness of the chart is more like [[Fuck Grapefruit]] a matter of opinion than an actual analysis based on actual statistics. [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 08:39, 3 June 2024 (UTC)

Most deaths are either due to involved cars or people doing races or stunts. [[Special:Contributions/172.68.192.196|172.68.192.196]] 21:36, 31 May 2024 (UTC) (para 2/4)

I would not count "died because plane crashed onto road" into car dangers, as I would not count F1 driver death into the same bucket as car commuters. [[Special:Contributions/172.68.192.196|172.68.192.196]] 21:36, 31 May 2024 (UTC) (para 3/4)
:So I would do the same for bikes. [[Special:Contributions/172.68.192.196|172.68.192.196]] 21:36, 31 May 2024 (UTC) (para 4/4)
::Agreed. Deaths caused by cars should not count against bikes unless "plane crashed onto road" would count against cars & 'flying by nuclear rocket' would count against the poor people walking below.

It's not actually true that a hot air balloon has only one possible direction of travel. It seemed relevant so I added a couple of sentences to the explanation. I suspect Randall is aware of this of course, being a weather nerd. [[Special:Contributions/162.158.74.69|162.158.74.69]] 00:28, 1 June 2024 (UTC)

Meh... A hot air balloon is not a "mode of transportation", that is it's not a means to go from location A (on the ground) to location B (on the ground) A hot air balloon is means of going ''Up'', and staying ''up'' for an reasonable period of time. In most balloon rides, the "destination" is irrelevant, the purpose of the ride is to reach altitude, not travel horizontally. I feel Randall misses the point of balloons here. It shouldn't be only the graph, because it's not a "Mode of transport".
[[User:Zeimusu|Zeimusu]] ([[User talk:Zeimusu|talk]]) 21:13, 1 June 2024 (UTC)
:The graph only addresses how convenient\dangerous things are as a form of transport. A Slip-N-Slide could easily have made the list, if Randall had viewed any such record attempts lately. Putting only practical modes of transport on the chart, would leave the lower right empty. If one wanted to know whether hot-air balloon ''was'' a practical mode of transport, one could theoretically consult a chart like this to find out that it isn't.
:[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 21:59, 2 June 2024 (UTC)

Are American hot air balloonists commonly fond of taking sniper rifles up with them? [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 23:11, 31 May 2024 (UTC)

Dangerous to whom is relevant. Yes, cars are less dangerous to the driver than bicycles and pedestrians, but that is because the main threat to bicyclists and pedestrians is cars. If you count victim deaths in addition to perpetrator deaths, then cars are the least safe vehicle. [[Special:Contributions/172.71.99.30|172.71.99.30]] 01:56, 1 June 2024 (UTC)Regret

Are scooters really more convenient than bikes or does Randall just think they are cooler? Please discuss. [[Special:Contributions/172.69.58.128|172.69.58.128]] 04:17, 1 June 2024 (UTC)
:The convenience of scooters probably includes their relative storability/carryability between uses, easier to hop on and off (also you might get away with scootering down long corridors where a bike would be (more) frowned upon) and takes less maintenance. (Electric ones do have the additional fuss of charging (and ICE ones needing fuel/being more disruptively noisy), but hard to tell whether Randall means shove-along or motorised in any way). Probably he doesn't mean mopeds (also known as 'scooters', in some contexts), but they also may be considered like bicycles but marginally more convenient (when fuelled/serviced) and commensurately a little bit more dangerous (though I'd argue further over to near full-on-motorbikes, myself). But it's a lot of speculation either way. [[Special:Contributions/172.71.242.28|172.71.242.28]] 11:32, 1 June 2024 (UTC)
:Very inconvenient, and definitely more dangerous. No way to transport anything except in a rucksack. Terribly small wheels. Muscle-powered very strenous compared to a bike. Electrical make you freeze to death in winter. Wear down very quickly (bearings in wheels and steering, brakes). Only use for scooters are flat, smooth passages, certainly indoors. --[[Special:Contributions/172.71.246.69|172.71.246.69]] 09:49, 2 June 2024 (UTC)
:I think Randall's use of "scooters" here, may include mopeds & ebikes, since ebikes aren't listed here, yet are roughly equivalent to (or even just ''are'') a moped, while mopeds & high-output ebikes <45MPH are often classed among "scooters". [[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 21:59, 2 June 2024 (UTC)
::A "high-output e-bike" is (or should) be classified under "motorbike". And I already (before I read this) included reference to electrically-assisted bicycles under the Bicycles entry itself. There may be various distinctions recognised under different local laws, but power-assisted-pedalling versions (augmenting, but not making insigificant, the riders' 'normal' effort) and power-rather-than-pedalling versions (which would go all the way up to those with ''no pedals'', totally reliant upon the motor) would probably sit either side of the notional divide that might be recognised by those in charge of classifying them. [[Special:Contributions/172.69.79.182|172.69.79.182]] 22:43, 2 June 2024 (UTC)
:::I suspect what ProphetZarquon was getting at is that they are often ''referred to'' as "scooters", as opposed to legally classed as such.[[Special:Contributions/172.70.163.121|172.70.163.121]] 10:41, 3 June 2024 (UTC)

I would expect that unicycles are more dangerous than bicycles. For that matter, bicycles are probably more dangerous than tricycles, and those would be slightly less safe than quadcycles. There we probably hit the optimal point, but I doubt anyone has done an in dept study into this matter. Just for starters: a double blind test would not be particularly safe for the riders. [[Special:Contributions/172.71.98.101|172.71.98.101]] 07:00, 1 June 2024 (UTC)
:When you have learnt how to ride a bike, a tricycle can actually be ''harder'' to ride, due to having to unlearn your existing bicycling instincts. To turn (or not to turn) on a bicycle involves at least 'microleaning', as well as steering, which can actually work against the steering geometry on a tricyle (perhaps a quadricycle is less effected, as one reverts to car-like behaviour/has to account for uneven road surfaces even more differently). Before you have the bike-riding skills (especially on front-wheel-pedal kids' trikes, which have yet more things going on than proper road-cycling tricycles) you generally don't get into the wrong mode of balance where you actually veer off exactly the opposite way to what you intend and maybe start to lift one of the rear wheels off the ground, or more.
:For similar reasons, it's much better to have a completely new passenger ('stoker') on a tandem who is not a cyclist than one who is (but it being their first time on a tandem). The 'steersman' does not need too much complication from their "luggage" instinctively leaning on their own (or unconsciously tugging left/right on their fixed-handlebars), at least until they've practiced their coordination so that there's just the right amount of weight redistribution at the right time to make the whole machine correctly metastable for the circumstances. A non-cyclist can generally be asked to "just sit there and pedal" and not, despite being told, throw themselves around in various ways not related to the (synchronised with the steersman) pedal-revs. [[Special:Contributions/172.71.242.28|172.71.242.28]] 11:32, 1 June 2024 (UTC)

Hot air balloons can be particularly dangerous in large groups, each being approximately 1.11% of an extinction level event. [[Special:Contributions/172.69.246.143|172.69.246.143]] 15:53, 1 June 2024 (UTC)

== Other in-between modes of transport? ==

So which modes of transports belong in the white band between the "Zone of specialty and recreational vehicles" and the Hot air balloons? I would suggest the Autogyro (see [[1972:_Autogyros|#1972]]) between the skis and the hot air balloon. Any other suggestions?

== Explain "sign error" (done?) ==

I came here to find out what a sign-error is, but the description assumes I already know. {{unsigned ip|162.158.74.69|22:58, 31 May 2024}}
: I think he means if you have erroneously given a negative as a positive, and thereby flipped your y-axis the wrong way up - making inconvenient things appear convenient.[[Special:Contributions/172.70.162.186|172.70.162.186]] 08:33, 3 June 2024 (UTC)
::''And'' flipped the x-axis. Or at least how you treat it. Note that one axis is "more is better" (convenience) and the other is "less is better" (danger), so any analysis that looks at comparative overall desirability has to treat one axis's position in a negative manner, whether seeking the coordinate with least deviation from perfection, the most deviation from imperfection, the most desirable vector away from a midpoint or whatever. The choice of exactly how to compare might juggle the effective linear rank of all items, although it visually looks like Trains would always rank first in most treatments (except those with a very weird weighting between the two measures, or even an 'ideal' position not on the "not dangerous at all" edge but maybe at a 'comfortably desired' amount of thrill).
::So you need to apply exactly one sign-flip to identify the (normally) practical zone for being best (not very convenient and very dangerous; nor undangerous and inconvenient). Apply that sign-flip to ''x'' instead of ''y'' (or vice-versa, depending upon your goal-seeking method) and you're identifying Hot Air Balloons as your perfect solution instead of (by Randall's apparent perception) Trains.
::At this point, you've not (just) flipped the Convenience axis over. Either you've flipped ''both'' around or you're now not doing the sanity-check on the original graph ''at all'' and just relying upon your doubly-missigned 'algorithm' (one input flipped, the other ''de''flipped).
::A related sign-error coordinate thing is in 3D data, where left-handed and right-handed coordinate systems are just a single sign-flip away (or all three flipped!), but often also combined with whether you should go with ''z'' being 'into' (or out of!) the paper graph (standard x-along and y-up, from 2D graphing) or it being 'up' (or 'down'!) with x/y being both laid horizontally. Both can be made true on a 'tabletop map', but less obvious which is the best way to use on a vertical screen. All this before you start applying other rotations, of course, to the data you initially define in whichever choice of fundemental coordinates you wish. But it can be confusing if you're unsure as to which baseline (left/right-handed, and "which axis is ''z''" probably less certain than subsequently filling in where the other two are) either to implement yourself or to interact with when you start work atop another basic implementation. I probably had more designs come up sideways (in some manner) than I ever did have them accidentally mirrored, whenever I started to dabble in a new 3D platform.

669: Experiment

2024-05-31T18:29:24Z

172.70.163.121: Undo revision 343368 by 172.70.134.147 (talk) No suggestion of Beret Guy. Every suggestion of a vacuum.

{{comic
| number = 669
| date = November 30, 2009
| title = Experiment
| image = experiment.png
| titletext = The other two are still lost on the infinite plane of uniform density.
}}

==Explanation==
Problems in the study of {{w|kinematics}} often idealize the environment of the problem for the sake of simplicity. Specifically, it is assumed that objects are moving in a {{w|vacuum}} and that there is no {{w|friction}}. Then the complicated effects of air resistance and surface frictions can be ignored, and the more basic principles of momentum and energy can be explored. In more advanced physics, it is often easier or necessary to ignore friction if the process being studied is very complicated. So it could be said that "physics professors like working in a frictionless vacuum".

In the comic, [[Black Hat]] and [[Danish]] have interpreted that statement to mean that physics professors like doing their work while they are in a frictionless vacuum, instead of liking to work with problems which are set in a frictionless vacuum. Apparently, they have drugged a physics professor and put him in a glass dome (with his laptop so he can work) which they can evacuate and make frictionless. The professor wakes up confused from the drugs, and as the air is pumped out to make a vacuum (presumably slowly enough to prevent {{w|explosive decompression}} from coming into play), his words fade to silence because sound waves requires a substance such as air to travel through. As he starts to panic, he tries to run, presumably for the door we see in the last panels. However, without friction on the floor, he cannot exert any force to move forward, and his feet skate uselessly on the ground until he loses balance and falls. At this point he is probably suffering from {{w|asphyxiation}}. Black Hat and Danish are observing from outside the dome, and decide that physics professors have lied about liking to work in frictionless vacuums.

The title text refers to another common idealization, of an infinite {{w|plane}} of uniform {{w|density}}. An infinite plane extends forever in two dimensions, which makes calculations easier because surface-related properties are identical everywhere. "Uniform density" could refer to the mass density of the plane, or more likely an {{w|electric charge}} density, which makes a common problem in basic {{w|electromagnetism}} involving calculating the {{w|electric field}}. The "other two physicists" that Black Hat and Danish are experimenting on are lost on the infinite plane, since there are no edges or landmarks anywhere to give them direction.

It should be noted that, although a vacuum can be approximated using a {{w|vacuum pump}}, {{w|frictionless plane|frictionless surfaces}} and infinite planes are only imaginary constructs and do not exist in our universe.{{Citation needed}}{{Actual citation needed|reason=A source for this could be interesting to read}}

2939: Complexity Analysis

2024-05-30T08:11:42Z

}}

==Explanation==
{{incomplete|Created by a PERPETUALLY OPTIMISTIC BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
[[Cueball]] is teaching about an algorithm's complexity. The average-case runtime of the algorithm is written as O(n log n), in {{w|Big O notation}}, expressing the asymptotic runtime of the algorithm as the number of inputs to it grows larger and larger. This is an error by [[Randall]] (or Cueball), as Big-O notation represents only the worst-case, not average-case time complexity.

The "best case" for an algorithm is typically its runtime when its inputs have optimal values and it runs in as little time as possible. The joke here is that not only does it run quicker than this by being terminated early because it's 'unnecessary', but its runtime appears to be an hour shorter still because of an act of Congress changing {{w|daylight saving time}}, giving it an end time (in local time) that is an hour less than it would otherwise have been. Potentially this would result in an end time that is less than its start time, and therefore an apparently ''negative'' 'runtime'. Daylight saving time is a [[:Category:Daylight saving time|recurrent theme]] on xkcd, and it is clear that Randall is not a fan, so Congress making surprise DST changes is another way for Randall to mock the concept.

The "worst case" refers to the movie {{w|Groundhog Day (movie)|Groundhog Day}}, in which the same events occur over and over in a sort of time loop. (This movie has been referenced before in [[1076|1076: Groundhog Day]].) If the hardware running the algorithm is stuck in this kind of loop that resets to a previous time before it ever gets finished, then the algorithm would never terminate. This gives rise to a philosophical question as to whether the whole world is reset after every day, or just the town where the movie takes place. If it is just the town, and you can still connect to their hardware from outside, then from that perspective the algorithm would appear to be taking an interminably long time to run. If the whole world resets, since people (aside from the movie's main character) do not experience the reset of the day, it would only appear to take as long as it did on the final day when it successfully completed.

This may be an indirect reference to the {{w|halting problem}}, a famous problem in computer science. The halting problem is {{w|undecidable}}, meaning that there is no general algorithm that can tell whether a given algorithm will halt.

The title text refers to perhaps an even more famous problem in computer science: {{w|P versus NP problem|P versus NP}}. This asks whether every problem whose solution can be quickly verified (in nondeterministic polynomial time, {{w|NP_(complexity)|NP}}) can also be quickly solved (in polynomial time, {{w|polynomial time|P}}). The P-versus-NP problem is one of the seven {{w|Millennium Prize Problems}}, and as such has a $1 million prize for its solution. Presumably, the problem discussed here is in NP, so if P=NP, its worst-case runtime would be some polynomial ''O(nk)''. However, P vs. NP is a Millennium Prize Problem for a reason, and most computer scientists expect that P != NP, so hoping for a breakthrough in proving P=NP is "perpetually optimistic". This may be a reference to {{w|Optimism bias}} and the {{w|Planning Fallacy}}, whereby people tend to assume that the most favourable outcome will be is the most likely.

1048: Emotion

2024-05-29T12:50:47Z

172.70.163.121: /* Explanation */

{{comic
| number = 1048
| date = April 27, 2012
| title = Emotion
| image = emotion.png
| titletext = Fortunately, the internet has a virtually inexhaustible supply of code that doesn't work and people who are wrong, which bodes well for a return to normalcy. [Note: Click to read context for the cancer comics. She's doing well.]
}}
{{Quote| In October my fiancée was diagnosed with stage III breast cancer. [...] She’s been in nonstop treatment for the last eight months, which has been an emotional and physical ordeal that’s hard to describe. We both have all the support we could ask for—including an incredible medical team—and we’ve had some really good moments during these months, but it’s still a terrifying and isolating experience. Treatment is ongoing, and there’s no well-defined end point; things are going to continue to be scary and difficult for a while.|[[Randall Munroe]]}}
Here's the [http://blog.xkcd.com/2011/06/30/family-illness/ link] referenced in the image text, which is a blog post from 2011 regarding his fiancée's breast cancer.

==Explanation==
This is a mostly serious comic in which [[Randall]] expresses his thoughts while his fiancée started to suffer from {{w|breast cancer}}. He doesn't care about many things like politics anymore, there is just his fiancée's cancer and his romance with her. This is one of many [[:Category:Cancer|comics about cancer]] he made because of her cancer.

Some of his withdrawn activities are shown here:
*Politics became prominent in 2008 due to the upcoming {{w|United States presidential election, 2008|US presidential election in November 2008}}.
*"Code not working even though it ''should'' work" is a common frustration in software development, when the developer is convinced to have covered every possible scenario, but their code still does not run as expected, because of some obscure tiny problem which they didn't think of and which often takes much time (and frustration) to find.
*{{w|Joss Whedon}} is best known as the creator and showrunner of the television series ''{{w|Buffy the Vampire Slayer (TV series)|Buffy the Vampire Slayer}}'' (1997–2003), ''{{w|Angel (1999 TV series)|Angel}}'' (1999–2004) and ''{{w|Firefly (TV series)|Firefly}}'' (2002), so he's the "cause" of emotions for Randall during the time they were aired.
*"People being wrong on the internet" is something that can easily annoy and preoccupy an internet-savvy guy like Randall, who knows the things they're (incorrectly) talking about; this was previously dealt with in the comic [[386: Duty Calls]].

Eventually, Randall's fiancée's cancer, once diagnosed, monopolizes almost all of his emotions, wiping out nearly everything else as insignificant in comparison. Only a sliver of romance and tiny bits of 'people being wrong on the Internet' appear to occupy the small amount of space in his mind not taken up by cancer. As the threat posed by the cancer slowly wanes, romance can expand out again (with a small peak of romance around mid- to late-2011, presumably due to his marriage to his aforementioned fiancée). As the thoughts of cancer continue to gradually recede from Randall's mind, a space opens up (the question marks) that the cancer concern used to occupy. The ordeal wiped out all the previous, more trivial concerns, pre-occupying him entirely with the disease. Now that there is a little less reason to worry, he's not used to thinking about anything else. His previous preoccupations no longer seem important, so what to fill his time with?

==Transcript==
:[A graph showing the approximate fractional causes of Randall's emotions, with percentages on the Y axis and time on the X axis. "Politics", "Romance", "Code not working even though it ''should'' work", "people being wrong on the internet", and "other" all vary all throughout the time period from 2006 to midway 2010. There is a wedge of Joss Whedon that tapers out starting from 2006 to around mid 2007. There is a noticeable increase in "Politics" around fall, 2008 that tapers off sharply afterwards and appears again in the second half on 2010, until..

:Around approximately September 2010, everything else is compressed into a tiny fraction of around 2-3%. The rest is filled with cancer. The tiny wedge of everything does begin to slowly expand to be filled half with romance and half with an area filled with question marks.]

1701: Speed and Danger

2024-05-23T10:37:51Z

172.70.163.121: /* Explanation */ punc

{{comic
| number = 1701
| date = July 1, 2016
| title = Speed and Danger
| image = speed_and_danger.png
| titletext = NASCAR removed the passenger seats because drivers hated how astronauts kept riding along with them and loudly announcing "Ahh, what a nice and relaxing drive."
}}

==Explanation==

In this {{w|scatter plot}} [[Randall]] plots the speed of several vehicles (including people on foot for "normal sports") and how disastrous a crash would be. The punchline is that space {{w|rocket}}s travel so dangerously fast, and crashes are so utterly catastrophic, that it pushes literally every other kind of crash to the "slow and safe" corner by comparison. (A similar punchline was used in the title text of [[388: Fuck Grapefruit]].)

With the plot Randall makes the observation that the danger of a crash is greatly influenced by its speed and highlights the concept of relativity between what we perceive as "fast," normal sports and two different types of racing cars, vs. a much faster vehicle, a rocket during launch. A rocket may appear to ascend slowly (and of course it begins its ascent slowly), but on the way to orbit it ends up moving very fast. But before it reaches the more extreme speed regime it will be far away from the ground (and the casual observer), where there is nothing to compare this speed to as opposed to a race car speeding by a spectator during a race.

Apart from the high speed, there is also the altitude to take into account for a rocket launch, and the vast amount of fuel needed to get into orbit, and any sort of catastrophic failure is almost certainly fatal ({{w|Apollo 13}} notwithstanding).

Racing cars are often involved in crashes, but at that speed it is possible to construct them so even serious crashes may not be fatal. Although rockets are also made as safe as possible, it is a completely different regime of ''speed and danger'', and the risk of something going wrong during a take off is much higher,{{Actual citation needed}} and it is impossible to prevent a lethal disaster if the launch fails during the ascent. This results in a much higher mortality rate for each crashed rocket (probably 100%) vs. crashed sports/race cars.

Rocket launches are compared to "normal {{w|sports}}" (presumably meaning people running approximately 25 km/h, and possibly also {{w|polo}} {{w|horse}}s galloping approximately 40 km/h), {{w|NASCAR}} (which reaches speed of 320 km/h), and {{w|Formula One}} (F1), where the fastest race cars go 380 km/h. Although peak speed for an F1 car is higher than NASCAR, the average lap speed is much lower as F1 tracks have slow corners while NASCAR ovals can be negotiated with much less speed variation. It is also arguable whether F1 is more dangerous than NASCAR - there have been fewer fatalities in F1 this millennium, though fewer cars compete and races are of shorter duration. The 2016 Formula one season had 21 races, with each race lasting 1.5~3 hours. The NASCAR season had 36 races, with each race lasting 3~5 hours.

A rocket launched to reach the {{w|International Space Station|ISS}} needs to match the speed of the space station which moves at 27,600 km/h. A rocket that needs to {{w|Escape velocity|escape}} from Earth needs to reach 40,270 km/h, but so far no humans have escaped. However, the astronauts going to the Moon came close, with {{w|Apollo 10}} setting the {{w|List_of_spaceflight_records#Fastest|speed record}} for manned flights with 39,896 km/h. (It was only about [https://www.quora.com/Why-was-Apollo-10-the-fastest-of-all-the-Apollo-missions 0.4% faster] than the next 7 missions that, in contrast to Apollo 10, were supposed to land on the Moon). The lowest of the rocket speeds mentioned above is still more than 70 times as fast as the highest speed for race cars.

The title text serves to emphasize the point further, as an astronaut (used to the several G's of acceleration during takeoff and overall much higher speeds) would likely find a NASCAR car moving at ~300 km/h paltry compared to what they're acclimated to and has supposedly aggravated NASCAR drivers by making a point of saying so. And thus this is used to explain why there are no passenger seats in NASCAR cars, to prevent astronauts from joining the drivers for a nice, slow ride.

2787: Iceberg

172.70.163.121: Undo revision 342619 by Apollo11 (talk) Typoing Randall's name, and it may not be exactly him who has 'my' hobby. Best to just revert.

{{comic

| noexpand = true
| titletext = 90% of the iceberg is hidden beneath the water, but that 90% only uses 10% of its brain, so it's really only 9%.
}}

==Explanation==
This is another comic in the [[:Category:My Hobby|My Hobby series]]. The previous comic in this series was [[2733: Size Comparisons]], released just over 4 months prior. The [https://www.agcas.org.uk/write/MediaUploads/Resources/ITG/iceberg_metaphor.pdf iceberg metaphor] is a famous metaphor sometimes [https://pubmed.ncbi.nlm.nih.gov/31633371/ misattributed to Freud]. Just as a real iceberg floats with the vast majority of its body below the water's surface (often simplified as 90%, which does quite closely reflect the general range of buoyancy for ice in cold sea-water), the iceberg as metaphor represents a system where the large majority is unseen, invisible, or hidden in some way.

In this case, Ponytail is using it to illustrate the fact that about 95% of the mass in the universe does not appear to be in the form of ordinary ("{{w|baryonic matter|baryonic}}") matter, but rather {{w|dark matter}} and {{w|dark energy}}. Dark matter is known to not interact at all with ordinary baryonic matter except by gravity, and has been detected only by its gravitational effects. Excluding dark energy, dark matter accounts for about 85% of the total mass of the universe. So baryonic matter is like the "tip of the iceberg," visible to us above the surface, while dark matter is like the invisible majority of the iceberg below the surface.

The questioner in the audience purposely misunderstands the metaphor by taking it literally, thinking that Ponytail is saying that the part of an iceberg below the surface is literally made of dark matter. He points out that the {{w|Titanic}} sank after its hull was damaged by hitting the underwater part of an iceberg, which wouldn't be possible if it were made of dark matter. Cueball has previously been confused about dark matter in [[2186: Dark Matter]].

The title text references the myth that we use only 10% of our brain, and we could become more intelligent or powerful by "unlocking" the remaining 90%. If icebergs had brains, and the 90% in the "dark matter" part underwater used only 10% of its brain, while the tip also used 10% of its brain, then most of the cognition would occur in the underwater part. Hence the "9%" figure would refer to the cognition occurring underwater, with 1% of its cognition occurring above water. In reality, human beings use pretty much all of their brain. They just don't use it all at the same time; at any given instant, between 2% and 16% of neurons are firing, depending on how active the brain is in that moment. The effect of using one's whole brain would depend on precisely what is meant by that -- for example, all excitatory neurons firing with no inhibition for a prolonged period would be a {{w|seizure}} (most likely fatal), but there's no reason to exclude inhibitory neurons and adenosine when "using all of one's brain at once".

See [https://www.explainxkcd.com/wiki/index.php?title=1167:_Star_Trek_into_Darkness&diff=338228&oldid=338217 here], for details. (The stray "z", in the reason was supposed to be a comma, bloomin' touchscreen keyboard!)

Basically <code><nowiki>{{w|Page Title|link text}}</nowiki></code> supplies the necessary bits in what 'raw' might be <code><nowiki>[[wikipedia:Page Title|link text]]</nowiki></code>. Not ''much'' saving time, but just enough to be worthwhile. And far better than <code><nowiki>[https://en.m.wikipedia.org/wiki/Apollo_(spacecraft) whatever else you might use]</nowiki></code>... ;)

(PS, Columbia or Eagle? I mean, neither are ''called'' "Apollo". I suppose technically Eagle is ''more'' than a spacecraft, as it can land (or ditch into the sea, ironically for Aquarius!), but ''an'' Apollo craft could be anything from early boilerplate ones onward, and anything from the full stack to any free-flying component, and thus Apollo 11 is any/all of it from the base of its first stage to the tip of its escape-tower. Not to be pedantic, just wondering out loud. :p ) [[Special:Contributions/172.70.162.99|172.70.162.99]] 18:51, 26 March 2024 (UTC)

:(I have no idea what the second paragraph is so straight to the ps! ;) Comlumbia obvously, the Eagle already has so much hype (plus it bugs me that they put an ACTUAL EAGLE on the mission patch, it would've looked so much cooler with a rocket or the Eagle) That being said, the entire Apollo program was pretty freaking awsome, like, they did stuff that half a decade earlier people couldnt have dreamed of doing (techniclly they did dream it, but yk what i mean)!! As for the rocket itself, yes its called the Saturn V, but my names Apollo11 soooooooooooo :p And no worries beung pedantic, i love the decussion ;) [[User:Apollo11|Apollo11]] ([[User talk:Apollo11|talk]]) 19:01, 26 March 2024 (UTC)

# Use a spell-checker. (Or a spill-chucker!) You ''really'' need to, and you know you do.

You seem to be taking to heart the punctuation-before-the-Citation-needed standard (which is good, only sometimes it's even more complicated{{Citation needed}}),{{Citation needed}} but I see you recased an example of {{template|citation needed}} to {{template|Citation Needed}}, earlier. Now, it doesn't really matter because there are templates for "citation needed" and "Citation Needed". And also "cn" plus "fact" for the really lazy editors. ;) Anyway, all of these (maybe more, I'd have to check) redirect to the ''main'' "Citation needed" one. (Reflected in {{template|Actual citation needed}}, where "actual citation needed" ''plus'' "acn" redirect there, although {{template|Actual Citation Needed}} - "for completeness" - is actually a 'copy' template in its own right.) I wouldn't bother ''only'' changing various CN variations to "Citation needed"s (there ''is'' also a {{template|Citation neededs}}, but that's a '''s'''truckthrough version of "Citation needed" rather than an ungrammatical "Citation''s'' needed"!), but if you're already editing anything else, it would not at all hurt to get everything to capital-C small-n version. It gives the server ''very very slightly'' less work to do. ;) Probably. Not that it matters. But, as you seem to be a 'details person', I thought I'd pass on a detail you may not have already known... :p [[Special:Contributions/172.69.195.156|172.69.195.156]] 02:11, 27 February 2024 (UTC)
:You have not read the above (properly, at least). The {{template|Citation needed}} is the 'proper' one (for xkcd version of 'proper'), whilst {{template|cn}} is a lazy version that redirects. There's no reason at all to change "Citation needed" to "cn". (Not much reason to change the other way, either, but could be justified if one is editing something else..)
:I reverted the one where you made the "SIGHTation needed" into a CN, as that was clearly a deliberate variation by some past wag. No point changing it to the (not-quite-)standard one. [[Special:Contributions/172.69.194.115|172.69.194.115]] 17:31, 27 February 2024 (UTC)

== New User and User Talk pages ==

You're trying to be helpful, but... Anyone who ''really'' wants them will probably ask (or wait until they have page-creation rights themself). Looking at all the ones you've made for people, how many have even then been used (by the user concerned)? I suggest you don't need to create them, not even to un-redlink someone's [https://www.explainxkcd.com/wiki/index.php?limit=50&title=Special%3AContributions&contribs=user&target=Cleonis&namespace=&tagfilter=&start=&end= comic discussion] .sig links. It's normally not a big concern, and there's enough people who can help out if someone actually asks for it when you're not paying attention.
 As for the rest of us: ironically, I slightly wanted to drop a note to a long-term user the other day. (Comparatively, i.e. that they've been around for a bit longer than yourself.) They didn't have a User Talk page, so I resorted to a different way of commenting. They can create their own pages, if they want (and, if I was a username myself, I definitely could have by now). Yet I definitely wouldn't consider it valid to give the whole historic userbase any such 'missing' user-spaces.
 I'm no authority on this matter, or even a 'real user' in any properly identifiable way, but please do consider my advice that comes from long but informal experience of this kind of matter. You're not the first eager new contributor to try to help out like this. And you're not the first to have made the odd error (giving a spam-only account a Welcoming page ...which thankfully never got used to further the spamming, the account seemingly abandoned by that point ''anyway''), but of course this was probably before you even started lurking here (certainly before your current username, perhaps even prior to any IP-only-editing you might have done before that). Heck, some 'helpful' people even created the occasional User and/or User Talk spaces for IPs (don't do that, either, it's at best neutrally useless - even from my own IP-wise perspective).
 You at least seem to be doing it from a genuinely helpful position. For that, I thank you, and maybe also some of those actual new users do (if they've notice. But maybe no more. Unasked for, at least? [[Special:Contributions/172.71.242.29|172.71.242.29]] 16:13, 11 March 2024 (UTC)
:postscript - even while I was writing this, it seems that one of the users who ''hadn't'' seemed to want to use their page actually went and did so. And, elsewhere, proclaimed they weren't vandalising any more. I leave it up to others to make judgements on what's happening there, and the timing with respect to other recent interactions, but still not being particular auspicious. Time will tell how this all turns out. Anyway, just to note this.

==Official Apology==
From: Z1m

To: 42

Listen, I'm sorry for everything, 42. We all make mistakes sometimes, and I think the safest course of action so neither of us gets banned is to either leave each other alone or just say nice things to each other. 
I'm aware it's the Internet, and what I said can't be taken back (unless I delete it). 
But really, I'm sorry. 
To change the subject though, I'm glad I found someone who (used to) read Artemis Fowl! Maybe we can trade favorite book titles sometime! :)

:Just a note from a perpetual observer about the newline thing.
:Using one or more : (at the start of a line) gives indents. If you are already indenting, then a simple newline and : (or multiple ::s, the same numbed as you were on) handles the textflow properly and ''renders'' it as a linefeed, rather than 'merely' a simple whitespace that continues. I'm doing that here.
;I can also use other markup, like the ; I used here...
:...but that's not how that is meant to be used, and...
;:...only lines up with "<nowiki>;:</nowiki>", in this case...
:;...and not with "<nowiki>:;</nowiki>" in this other. ;)
:Honestly, though, that's not what ; is to be used for. It's actually really more for ";Item:Definition of some kind", like:
;Item:Definition of some kind
:Though is often repurposed as ";Unofficial 'header' title", within Talk pages, that doesn't create a TOC entry. Just just so gou know. :p
:If you're writing at the 'zero indent' level, then a double-linefeed in the wikisource forces a line-break in the HTML, but it looks messy in viewing/re-editing the markup, so one way to avoid that is to invoke the <nowiki> </nowiki>, even in the middle of an actual wikisource line! (But that can be confusing, so don't do that without ''good'' reason.
:I also prefer to use "<nowiki> </nowiki>" (it adheres to standard non-container extensible HTML tag notation better) and like to put it at the ''start'' of the new line text rather than at the end of the old one's (but this is practically the same – I just find that seeing <nowiki> </nowiki>s at the start of every intended new line is easier to visually check than having them at random column positions according to the paragraph length that precedes it, hence it's my preference only).
:Another useful note is that when you're in a wikitable markup, the 'contents' of a cell can have linebreaks. Whether a line-started "|" or a successive midline "||" (trust me, when you're used to wikitabls markup, you'll know what I'm saying!), the ''very first'' newline in the wikisource is understood as a renderable newline (because it's not the "|"-at-start-of-line of the next column's cell, or the "|-" tween-line, otherwise expected), but you need to invoke any second, third, etc linebreaks with one or other of the br-tag/double-newline/etc methods. Otherwise it'll just be treated as whitespace and 'unwrap' into a continuous second-para. (As always, if in doubt use the Preview button, check it appears like you think it ought to.)
:But there's ''loads'' of different ways to wikimarkup various conceptual layouts, and all kinds of different styles that you could adopt. This is just a "the more you know..!" infodump, which may ''or may not'' be useful to relatively new editors like yourselves. So take note or ignore, or ignore until you suddenly realise you might need to know these things, then try to make sense of it. Or ''maybe'' I'll be around to answer further questions!

A PSA is a {{w|Public Service Announcement}}. Some drivers, when having priority by the rules of the road (termed "{{w|Traffic#Passage_priority_(right_of_way)|right of way}}", in US legal statutes), will let others take it before them. This comic is saying that people who exhibit this behavior are actually {{w|The_Terminator|Terminator}}-style assassins, sent to kill people by sending them into contention with other traffic and making it look like an accident.

Despite the PSA's conspiratorial presentation, this is good advice. This gesture is sometimes called "the wave of death", because it is common for such "generous" drivers to forget about other lanes that also have priority over the crossing driver or pedestrian, and cluelessly wave them through right into the path of another car which is traveling at full speed. Always check for yourself that your way is clear, and if your view is blocked, sit tight. In this comic, there is a queue of vehicles (including a large tractor-trailer truck) held up by the 'considerate' driver that would obscure the immediate view of the moving vehicle at the most potentially dangerous time. Randall's exaggeration has comical intent and also could help make the advice more memorable - and therefore more likely to save lives.

The title text explains that Randall made this PSA because he has experienced this multiple times in the last month. Since this behavior is often catastrophically dangerous, he believes the action could only be performed by time-travelling assassins. As such, he has not accepted the right of way, and thus believes himself to have evaded death. He then says that, since he already knows this trick, the assassins should try harder. Such a claim that assassins are actively trying to murder him using "right of way" would be treated as a conspiracy theory by most people. Furthermore, if there really is an assassin with time-traveling capabilities out to get Randall, there would probably be more efficient ways to kill him (and make it look like an accident), like traveling back to when Randall was a child. The "try harder" bit also doesn't make sense for time travelers, since they can travel back to ''before'' he's learned this valuable lesson.

===Alternate interpretation of the waving gesture===

Note that in this comic, as illustrated, there is potentially sufficient room for the waiting car to pass the first set of lanes and (illegally) stop next to the median, protected from passing traffic on both sides, to stop halfway through its left turn to wait for the second stream of traffic to subside. Waiting in this turning area next to the median is a common maneuver in rural US areas where these types of non-signaled intersections are common, though it is illegal in many jurisdictions. (Turn lanes are not legally usable for merging in many, although not [https://le.utah.gov/xcode/Title41/Chapter6A/41-6a-S801.html?v=C41-6a-S801_2015051220150512 all], jurisdictions, &and stopping in an intersection is also not permitted.) There's no reason to assume that the would-be assassin is not simply waving the waiting car to the safety of the median area. Randall's message of caution is still sound, but he accidentally illustrated an intersection diagram that fails to optimally support his case.

172.70.163.121:

Did the best I could on the explanation, even if it's a bit clunky. [[User:Trogdor147|Trogdor147]] ([[User_talk:Trogdor147|talk]]) 03:59, 14 May 2024 (UTC)

Pretty lame strategy. Even with someone waving me on, when I get past them I'll look to the right to make sure. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 04:22, 14 May 2024 (UTC)
: Right? Just pull into the median in front of the left-turners, then re-assess the situation. --[[User:Coconut Galaxy|Coconut Galaxy]] ([[User talk:Coconut Galaxy|talk]]) 12:59, 14 May 2024 (UTC)
::Just an FYI: It's illegal to use turn lanes for merging, & illegal to wait mid-intersection. By law, you must not enter the intersection until the right-of-way is clear. No stopping partway through; that can get you a ticket.
::[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 18:07, 14 May 2024 (UTC)
:: As a pedestrian (amongst my other road-uses), I occasionally have to cross a two-lane carriageway (to the median, then across the opposite two-lane carriageway) near a junction (roundabout, in the UK; and the first lane dedicated to turning in (left, equiv. to a US right-turn) to the side-road) and the initial lane is often either entirely empty or jammed up by those trying to turn into the retail park that sits there. I have to juggle the kindness of drivers who will slow (or stay stopped) to let me across their lane with the possibility of having other (faster-moving) traffic still coming up on the other lane. It's possible to use the twixt-lane white line as a kind of unofficial demi-median (the stopped driver will not forget that they let you go there), but I'd rather not surprise the through-traffic lane by giving them an alarming glimpse of a pedestrian maybe about to step out in front of them, so I might try to indicate to the kind driver (with friendly gestures) that I'm observing someone coming up on their offside (due to slight bend, on entry to the junction, they might not see them in their own offside mirror), perhaps even then stand back and wave them past because ''I'' can see a glut of offside traffic, from my head-height position. Or just avoid those times of the day when there's heavy shopping/commuting traffic causing that sort of problem.
:: (Yes, it ''is'' a proper crossing point. Dropped kerbs for those that need dropped kerbs, though not given pelican/zebra/etc explicit crossing markings and signage. An alternate way 'across' is a walk down to a canal that the onward road crosses by bridge, under that bridge on the tow-path and then back to meet the opposite side of the road.)
:: The junction-exit carriageway is far simpler. You can see when traffic is coming down the through-road ''or'' spinning round the island from the RP exit (or U-turning from the first carriageway!) and either there's a third-of-a-mile queue backed up from the next junction or there's no traffic impeding those going that way to leave me with space to cross.
:: The opposite crossing is a matter of the 'easy' junction-exit carriageway (as just given) plus an unrestricted view of the fast-lane, but then you need to catch the eye of any queued turn-lane vehicles (and look at what round-the-roundabout traffic might be holding the front of that queue up, in the near future) to make sure that when you take advantage of a clear offside then the subsequent nearside cars don't start shuffling up. And recognise the oblivious/inconsiderate/obtuse drivers by their general road positioning and attitude at the wheel. (It's a bit of an art, but stood me in good stead so far.)
:: There is also, elsewher, a ''particularly'' akward right-turn (UK, remember) onto a mainish road, that I sometimes need to drive round. It comes in as single-becoming-double lane, but these days that double is buslane and singular other (from the right, the double-becoming-single is also buslane nearside, except for inward turners who aren't in contention with me but ''are'' potentially view-blocking). Between the two carriageways (which merge, at the single-lane side, as two standard single contra-carriageways beyond an actual light-controlled staggered pedestrian crossing) is the central turning refuge that I potentially need to pause in to turn right, and left-approaching traffic may need to pause in (crossing my path) to turn into the road I'm emerging from. The most problematic are the turning-in cars that ''don't signal'' (or far too late), given that everyone (not a bus) has to keep right anyway on this widened stretch, but some of them are keeping right in order to turn right. And driver-to-driver visual communication (or even seeing if they're glancing in your direction/meeting your questioning gaze) is isn't helped by angled windscreens often drowning out (apparent) driver-on-driver visibility by the reflection of the sky above. So it pays to be cautious, and taking a moment before taking apparent cues (arm waves, light flashes, etc) as you think they might be intended.

Uncontrolled intersection with a left turn onto a 4-lane road? US road design, combined with US car-centric settlement planning, must have been made by those more clever, trying-harder assassins that Randall mentions in the title text, and it looks like they've got a lot of people on their list.

: You are assuming the assassins are "good guys", it is just as likely that Randall will do something that most of us would regard as a good thing but it impedes the assassin's, or their master's, evil plan; akin to Skynet sending the Terminators to kill Sarah/Young John Connor to remove the human resistance as an effective counter to the machine uprising. There's also the possibility that Randall is part of a "butterfly effect" scenario where he doesn't directly do anything of note, but something he does will have downstream effects that result in someone else doing something impactful to the assassin's preferred future.[[Special:Contributions/172.70.135.56|172.70.135.56]] 16:01, 14 May 2024 (UTC)

:First, the people in the car usually don't think of the OTHER lane (and kids won't, either).
:Second, I am trying to teach my kids to look left and right and only cross the road when there are no cars. If a car approaches, they are to wait until it has passed. Well, but then the car STOPS and the kid gets irritated and doesn't know what to do, because when they are small they just stare at the car and not at the driver, so they never see the waving. And so we are at a stalemate, the car is just standing there, the kid is just standing there, and chances are the kid will decide to cross the road right at the same moment the driver decides he has waited long enough.--[[Special:Contributions/172.70.243.227|172.70.243.227]] 21:29, 14 May 2024 (UTC)

I remember when taking my driver's education class (in New Jersey, in 1987), the instructor made a point of teaching us to ignore civilians waving and to never wave other traffic anywhere. If you wave a car in this manner, and it ends up getting into a collision, you can be held liable for the damage. You could also be charged with directing traffic without authorization - something typically only done by law enforcement officers and road construction crews.

I must point out, no one has a privilege to go. The "right of way" only refers to the side of the road. Stop using the term wrong. [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 20:46, 14 May 2024 (UTC)

::Like everything else in the comic and the comments here, that depends on jurisdiction. For example, in Australia "right of way" doesn't exist - at least not as a right that can be asserted. Throughout the road rule legislation, references are made to situations where a driver has to give way to other traffic, but there is nothing that explicitly gives a driver "right of way" over any other traffic. As a driver I am obliged to recognise situations where I have to give priority to other drivers, but there is no explicit right to take priority. The legislation also requires all drivers to do what they can to avoid collisions. [[User:Paddles|Paddles]] ([[User talk:Paddles|talk]]) 23:38, 14 May 2024 (UTC)

I want to clarify that the initial post on this thread is not entirely correct, as it is dependent on the jurisdiction, whether it be on a national level, state level, etc. Where I am from in the United States in the state of Utah, for instance, it is codified in Utah traffic code 41-6a-801 Subsections (3)(b)(i) and (3)(d) (see https://le.utah.gov/xcode/Title41/Chapter6A/41-6a-S801.html?v=C41-6a-S801_2015051220150512 if you want) that traffic can turn into the turn lane and wait until the opportunity arises to merge, provided they do not travel further than 500 feet in that lane (in addition to other qualifications that are largely irrelevant to the present subject). While that is inapplicable in the case of this comic, as I do not know of ANY jurisdiction where turning onto a median itself is legal, that does not necessarily mean that it is illegal to turn into a dual direction turn lane and then merge into traffic in all jurisdictions. Apologies if I formatted this comment poorly.[[User:SilentLurker|SilentLurker]] ([[User talk:SilentLurker|talk]]) 23:00, 14 May 2024 (UTC)

If this has happened to Randall several times during the last month alone, then MAYBE he has a habit of stopping his car too far out and/or too far on the left? So that the left-turning time travellers would have difficulties getting past him?

1013: Wake Up Sheeple

2024-05-13T18:40:49Z

172.70.163.121: /* Explanation */ sp.

{{comic
| number = 1013
| date = February 6, 2012
| title = Wake Up Sheeple
| image = wake_up_sheeple.png
| titletext = You will be led to judgement like lambs to the slaughter--a simile whose existence, I might add, will not do your species any favors.
}}

==Explanation==
[[Cueball]] is going through the traditional street-protester refrain about the government having control over our lives and shouts "{{rw|wake_up|wake up}}, sheeple!" through a megaphone. ''{{w|Sheeple}}'' is a {{w|portmanteau}} of ''sheep'' and ''people'' used as a derisive term to describe people who thoughtlessly wander through their daily lives going exactly where they are "herded" by the powers that be.

However, in this comic, the Sheeple are humanoid sheep-men who have slumbered beneath the Earth for ten thousand years, and whom Cueball has inadvertently awoken with his repeated mantra, similar to saying "bloody mary" in a mirror three times (much as in [[555: Two Mirrors]]). The Sheeple appear to be some kind of {{w|Cthulhu_Mythos|eldritch}} {{tvtropes|EldritchAbomination|abomination}} who will destroy the human race, and judging from [[Megan|Megan's]] reaction and the off-panel voices, Cueball seems to be the only one previously unaware of their existence.

The title text says the humans will be led "like lambs to the slaughter" which is a phrase that appears many times in older texts, the Bible as an example. The phrase means that someone or something would be led to its destruction without it thinking to escape from the disaster. The Sheeple are likely to take it amiss, because it indicates the uncaring frequency with which humans kill juvenile sheep.
