141.101.99.163: /* Your suggestions! What should I ask? */

<big>{{TOC}}</big>'''Hey everyone! I got in touch with [[Randall Munroe]] himself!! Here's what you need to know.'''

I emailed him to ask for the official release date of [[36: Scientists]] (see [[36: Scientists#Trivia|the trivia for more info]]). Surprisingly, he got back to me! You can read the conversation, with a summary of his messages, below. I'll keep you posted if I receive more messages! You can [https://www.explainxkcd.com/wiki/index.php?title=User:FaviFake&action=watch add this page to your watchlist] to keep track of it. I haven't received his explicit permission to feature his messages in full, so it seemed ethical to hide his messages. My emails have not been altered, but in the copy-pasting, links have been removed. These emails were all hyperlinked, I now added back only a few links. The reason I waited a few days before publishing them is because I was very busy.

In his last email, Randall expressed willingness to answer a few more questions, particularly simpler, administrative questions (like the one he answered already), but kindly explained he prefers to avoid too much meta-commentary. Because I didn't want to come up with every question and I wanted to hear everyone, I'll try to send him some that you want, if he agrees to receiving more! You can [[#Your suggestions! What should I ask?|add your suggestions here!]].

Hi,
I'm an editor at explainxkcd.com, which you probably know is the wiki that explains all your comics and provides as much info as possible on them.
{| class="wikitable"
|''[In the copy-pasting, links have been removed. These emails were all hyperlinked, I now added back only a few links.]''
|}
In pursuit of that goal, we have always had an unsolved mystery only you can solve. Comic [[36: Scientists]] was originally posted as a duplicate of comic [[10: Pi Equals]]. You corrected this sometime between April 23, 2006 and July 5, 2006 , when the current version showed up in the web archive (see the two links). The comic looks like one of your old drawings.

So, explain xkcd thinks that when you realized your mistake (over three months after it was originally posted), you probably found an old unused drawing and posted it, to not make it stand out compared to the other comics from that time. This all means we have no date for this comic, since it could've been posted anytime between the two dates mentioned above. You can read more about this here. (If you're interested, we have a more comprehensive history of your webcomic here.)

Could you kindly help us figure this out by checking when you released comic #[[36]], so we can add an official date to it? This is one of the only official comics which we don't know the date of.

Kind regards,

FaviFake

| colspan="2" |Hello Randall,

Thank you so much for your response!! I'm certain the rest of the community will be thrilled to have an official answer.

Unfortunately, this is by far not the only "unsolved mystery" we have encountered in our research of your comic. Because we don't get to talk to you very often, I'd like to ask you if you can answer more of our many questions, if you're up for it. Of course, I do not want to annoy you or waste your time, so please let me know if this is something you'd enjoy! I will try to keep the questions entertaining for you.

Kind regards,

FaviFake

Thank you for the kind words!! I really appreciate the offer. Next time, I'm thinking of asking the community for other simple and administrative questions, because I'm sure I don't represent everyone.
{| class="wikitable"
|''I also asked for his permission to feature this conversation here:''
|}
(Also, would it be okay to feature your responses on our wiki?)

I had drafted the paragraphs below in advance and I'm not sure if they fall outside the boundaries you mentioned, but I figured I’d ask anyway since this is a topic the other editors are very curious about. Of course, no worries if you’d rather not get into the details! We have plenty of simpler questions we can't answer ourselves. Here you go:

On June 17, 2009, you released [[Conservation]] (along with IBM's accompanying blog post), the first comic created with IBM for their "A Smarter Planet" blog. You used the filename conservation.png, as usual. On August 11, 2009, the second comic of the series, [[Prescriptions]], was released (with its blog post), but this time you used an unusual filename: ibm_hc_1.png.

We initially believed these were the only comics you created, mainly because they were the only ones featured on your page xkcd.com/asmarterplanet, but a little over a month ago we discovered two additional never-before-seen comics by experimenting with the image URLs for [[ibm_hc_2]].png and [[ibm_hc_3]].png. We believe you created these two comics as part of the IBM partnership, but for some reason they were never released publicly and were only accessible from imgs.xkcd.com. (Interestingly enough, they are still available!)

Any additional info you can give us would help a ton! For example: their titles, when they were drawn or supposed to be released, or why they were never officially published. Thank you!

{{notice|Update: I haven't heard back. I'm planning to send a final email with a few of the quickest and smaller questions, so if you have any, no matter how small, ask away!}}
===What I think I should reply back===
*I first asked for permission to make the conversation public, so you all can read what he said. I wasn't told not to make it public, I just think I should ask for permission first. I'm not even sure if this was the right thing. If you have thoughts, [[User talk:FaviFake#Contacting Randall Munroe|please send them to me on my talk page]]!
*I didn't think it was fair to do everything myself, so I wanted to also hear what you wanted to ask! Randall asked for simpler, administrative questions (like the one he answered), and not ones that required too much explaining. Please add your suggestions to the section below!
*I think in the first message we should send some of the easiest questions to answer, quick ones like "when was this released", and then we can start to ask slightly more complex (but still administrative) questions.

===Your suggestions! What should I ask?===
{{notice|

Format your suggestions like this:

<nowiki>'''SUMMARY OF SUGGESTION --~~~~''' </nowiki>

{{Done}}'''[[ibm_hc_2]] and [[ibm_hc_3]] (newly-discovered comics) and comic [[36: Scientists]]''' --[[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 16:34, 21 February 2025 (UTC)
:I asked this one already, because I assume it's the most important one right now. You can [[#Email thread|see my question above]].

'''Why were the first comics [[LiveJournal|uploaded seemingly at random]]? --[[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 21:51, 22 February 2025 (UTC)
:Initially, randall posted his comics to LiveJournal ([[LiveJournal|learn more here]]). The new xkcd website opened on January 1, 2006, and the backlog of 41 comics from LiveJournal from [[1: Barrel - Part 1]] to [[44: Love]] was transferred on the same day, but in a completely different order. The only comic that has the same number on both sites is [[3: Island (sketch)]], while all the other comics were uploaded seemingly at random. Also, only eleven of the original comic titles were reused of the new site, and even among the last eleven comics posted on both sites, only six used the same title.

'''When was [[Blue Eyes]] released? --[[User:FaviFake|FaviFake]] ([[User talk:FaviFake|talk]]) 11:01, 23 February 2025 (UTC)'''
:[[xkcd]]'s [[Blue Eyes]] puzzle is a logic puzzle posted around the same time as comic [[169: Words that End in GRY]]. [[Randall]] calls it "The Hardest Logic Puzzle in the World" on its page, but whether it really is the hardest is up to speculation. This is incorrect, as the comic was available long before October 11, 2006. The earliest date we have is [https://web.archive.org/web/20041024201125/http://68.57.186.221:8080/ October 24th, 2004] (see fourth link on the page), and the earliest version of the comic is from [https://web.archive.org/web/20041109034300/http://68.57.186.221:8080/blue_eyes.html November 4th, 2004]. Additionally, both the puzzle [https://xkcd.com/solution.html and the solution] (here's an [https://web.archive.org/web/20061102070433/https://xkcd.com/solution.html earlier version of the solution])were modified and updated several times since its release.

'''Why are some of the april fools' comics late? - [[Special:Contributions/172.71.146.108|172.71.146.108]] 18:55, 22 February 2025 (UTC)'''
:I'm fairly sure we've had this answered already ("things just weren't quite ready/more testing was needed") for some of the more technical ones, in some other place. Whether we can get more detail and for ''every'' not-on-time might be a matter of him having to remember the precise circumstances. And I also would feel uncomfortable if this turned into "why was <random non-April Fool comic> late?". Or early. (When doing Rightpondian book-tours, sometimes surprisingly early, but every now and then it seems he manages to release them from his native Leftpondia even early here in the Rightpondian day.) But this is far too much detail (and far too much expectation), of no importance so long as he continues to average out at three regular comics a week and ''if he wants to'', and ''when he can'', anything a bit more special.
:Consider this a downvote on bothering him with this question, but that's of course only my opinion, in leiu of anything more constructive to add ("What's your favourite cheese..?") [[Special:Contributions/172.69.79.190|172.69.79.190]] 19:42, 22 February 2025 (UTC)

'''What happened to the transcripts in the JSON interface --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 17:38, 23 February 2025 (UTC)'''
:On the [https://xkcd.com/about/ about] page of xkcd there is a description of where:
Is there an interface for automated systems to access comics and metadata?
:Read more here [[Transcript]]. And on this page there is a [[Transcript#End%20of%20transcripts|description]] about how the json info got messed up after [[1608: Hoverboard]] and how they completely ended after [[1677: Contrails]] which had the transcript of [[1674: Adult]].

::::I feel like the answer would either be unsatisfying, or unsurprising. Releasing too many articles may disincentivize people from buying the books, the YouTube page is better marketing, people aren't asking interesting questions, the increased popularity of the article has led to too many questions being asked and it becomes increasingly unfair to answer one over the other. There's a possible litany of reasons without considering other more personal reasons that Randall may not want to share. Also, (and this is my completely unfair opinion) I personally feel like any question asking "why?" is meta-commentary and out of scope. It also feels like entitlement when you ask why someone isn't giving you even more stuff for free. [[Special:Contributions/172.69.23.94|172.69.23.94]] 19:25, 3 March 2025 (UTC)

2120: Brain Hemispheres

2025-03-06T10:43:54Z

141.101.99.163: /* Explanation */ Correct format (those who use it really need to have the basic inkling).

{{comic
| number = 2120
| date = March 6, 2019
| title = Brain Hemispheres
| image = brain_hemispheres.png
| titletext = Neurologically speaking, the LEFT hand is actually the one at the end of the RIGHT arm.
}}

==Explanation==
As a general rule, each cerebral hemisphere controls the opposite side of the body; things on the left half of the body are controlled by the right side of the brain and vice-versa. Biology is complicated,{{Citation needed}} of course, so as with most biology "rules" there are exceptions, such as the {{w|cranial nerves}}, but it's true for most motor functions, if not strictly correct in all cases.

[[Randall]] spoofs this by saying that rather than controlling the left half of the body, the right brain controls the top. This Euler-diagram-like picture echoes maps that display a {{w|territorial dispute}}, suggesting that the halves of your brain fight for control of the region, or "{{w|dual control}}" like in an airplane, where the pilot and the copilot both can control the plane at any time. The reorganization also leaves a gap in the bottom left, implying that the left leg is not controlled by any part of the brain, and instead has a mind of its own.

The title text proposes that the hands should be referred to not by their physical location, but by the hemisphere of the brain they're connected to. Of course, this is not only silly but inconsistent: if the hands were labelled by hemispheres of the brain, the same would presumably apply to the arms. Furthermore, there would be no reason to give left/right names to the hemispheres themselves, since their placement in the skull would be irrelevant.

==Transcript==
:[Cueball is shown with the right half of his brain (on the viewer's left) colored in orange and the left half (on the viewer's right) in iris blue. An iris blue box is overlaid over the right half of the body (on the viewer's left), and an orange box is overlaid over the top half. The boxes are overlapping in a greenish color on the upper right quarter of the body (on the viewer's left).]

2483: Linked List Interview Problem

2025-03-03T20:15:50Z

141.101.99.163: /* Explanation */ Depends upon the coder, the code, the things you're actually trying to do *and* in what development environment. No simple generalusation possible.

{{comic
| number = 2483
| date = June 30, 2021
| title = Linked List Interview Problem
| image = linked_list_interview_problem.png
| titletext = I'd traverse it myself, but it's singly linked, so I'm worried that I won't be able to find my way back to 2021.
}}

==Explanation==
This is another one of [[Randall|Randall's]] [[:Category:Tips|Tips]], this time a coding interview tip.

In computer programming, a {{w|linked list}} is a type of data structure that stores data throughout memory accompanied with memory addresses of the next, and potentially previous data point, establishing a relative ordering for a collection of data. Several common software engineering interview questions involve manipulating or otherwise interacting with linked lists. Possibly because programmers in the current day rarely work with linked lists directly, Randall suggests that such structures belong in a "technology museum," and thinks it would be more beneficial to mankind to email the list to such a museum rather than perform any useful work with it.

A linked list is a way to store sequential data in computer memory. Each piece of data is stored with a pointer to the next piece. This makes it very easy to add new data in the middle, since only one existing pointer must change to point to the new data. The drawback of a naive implementation can be that finding data may require following the entire chain. Technical programming interviewers like to see if applicants are familiar with the structure and the computational complexity concept itself.

Linked lists are, historically, one of the two main data structures that represent sequential data, along with arrays. Unlike arrays, they have the theoretical advantage of {{w|Big O notation|O(1)}} insertions and deletions thanks to not needing to reallocate the entire structure, but have O(n) random access (see {{w|Linked_list#Linked_lists_vs._dynamic_arrays|comparisons}}). However, modern processors' cache structure favors data that are located next to each other, pre-fetching the adjacent items, and modern processors can perform bulk memory moves, making resize operations faster. Finally, using linked lists usually implies dynamic allocation of each list member as opposed to reserving memory for a bunch of items in a bulk and then using that memory once an item has to be added. Memory allocation tends to be slow on modern systems and adds overhead for managing the information, which byte is allocated for what item, which can be significant, particularly for smaller data items; many small allocations also tend to fragment memory, which can lead to it being wasted and unavailable to the app later, particularly in long-running processes such as web servers. These properties tend to make linked lists poorly suited for most system programming applications in which a programmer might write algorithms to manipulate data structures, instead of using existing libraries.

Modern programming languages usually provide abstractions (often named "array," "vector" or "list") which interact with the sequential data at the memory level, providing access to this data while using arrays, linked lists, hybrids of the aforementioned technologies, or other approaches, and the programmer doesn't necessarily need to care one way or another. Additionally the time a malloc() and a free() take, as well of cache considerations may make linked lists way slower than arrays or vectors, very much depending upon how either compiler or interpreter converts the user's code/script into actual machine implementation (in some cases, it's possible that the way it is ultimately handled is ''identical'', though in others it may be possible for either/both of them to be run less than optimally compared to the best usage case). Knowing the underlying concepts is still useful, however, when creating fast running code which scales well to large data, avoiding (e.g.) traversing the list over and over again, or performing particularly inefficient operations.

Cueball's code implements a routine whose name implies that it does a mundane task, specifically traversing a linked list, but in fact emails the contents of the list to a technology museum. This could reveal private data that might be stored in a linked list, such as bank account numbers, medical information, passwords, etc., and would thus be a terrible idea. This is why interviewers - presumably job interviewers - would "get really mad".

In the title text, a {{w|Linked_list#Singly_linked_list|singly linked list}} contains pointers to traverse the list in only one direction; namely, from the head to the end. By contrast, each element in a {{w|Linked_list#Doubly_linked_list|doubly linked list}} contains pointers to both the "next" and "previous" elements, enabling traversal in either direction. Randall continues the implication that such lists are obsolete by implying that traversing such a list would be akin to time travel. Without the "previous element" pointers, Randall is concerned he would not be able to reverse the time travel, as he could not traverse the list in the reverse direction.

==Transcript==
:[Cueball is writing on a whiteboard with a blue pen with Ponytail looking over his shoulder. The text on the board is unreadable, but it is is written in blue above them. It is a piece of code and it reads:]

Talk:1475: Technically

2025-02-12T08:33:11Z

141.101.99.163: Undo revision 365306 by 172.68.234.85 (talk) Seemingly random reversions/snippings? Can't see any good reasons for that.

Technically, it's poor form and rude to ignore someone based on *Clicks Random page* [[User:Xseo|Xseo]] ([[User talk:Xseo|talk]]) 13:45, 19 January 2015 (UTC)

It's also possible that Cueball is purposefully inviting another "technically" sentence by stating he's looking at a bug, since it's unlikely he's looking at a member of the order Hemiptera. [[Special:Contributions/108.162.216.85|108.162.216.85]] 14:21, 19 January 2015 (UTC)

Well, it seems that White hat is responding to being asked if he is taking drugs, and technically, any food item that is consumed only for its taste or other effect on the body and mind, such as chocolate, could be argued to be a drug by a combination of both definitions given in the explanation. [[Special:Contributions/108.162.254.85|108.162.254.85]] 17:39, 19 January 2015 (UTC)

Along the same lines as the "bug" statement, does "a rock with a fossil in it" invite any sort of technical correction? I wouldn't know, personally, but there might be some people out there who would argue that since the fossil was a rock, or some other quibble about the phrase? [[Special:Contributions/108.162.238.192|108.162.238.192]] 20:19, 19 January 2015 (UTC)
:At that point, I'd say we're drastically overthinking this. Rocks are not in and of themselves fossils, but they are the most common substance in which fossils are found.

It seems highly likely that, as per previous comments, both the bug and fossil inclusions are not just purely distractions, but references to items that would commonly invoke pedantic 'technical corrections'.

:"The title text starts to pedantically over-apply Cueball's rule to the comic panel, noting that technically White Hat's sentence started with the word 'well' instead of the word 'technically', and thus Cueball is wrong to have ignored it."

"Whales are not fish" is a very poor example: it's not a technicality, but a very major and quite obvious difference. At least where I live, most people are aware of this, except for very small children or *extremely* uneducated persons. The other examples ("Peanuts are not nuts" and "Tomatoes are fruit") are *way* more appropriate. --[[Special:Contributions/108.162.231.55|108.162.231.55]] 00:48, 1 February 2015 (UTC)
:I would disagree that its a poor example, and I would wager that the majority of people couldn't give the basic definition of a mammal. Whales and fish both swim in the sea, both look alike (albeit on different scales), and are markedly similar in other ways. I know that whales are mammals rather than fish, but I couldn't explain all the differences. I certainly wouldn't call someone extremely uneducated if they thought whales were fish, as to me it is a fairly logical conclusion to come to. --[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 17:21, 3 February 2015 (UTC)
::Actually, the non-technical definition of "fish" is that it swims in water, does not walk on land, and breaths water. And any modern third grader knows that whales breath air, despite fitting the other criteria. Anonymous 20:16, 10 March 2015 (UTC)

3032: Skew-T Log-P

2025-01-02T15:04:35Z

141.101.99.163: /* Explanation */

{{comic
| number = 3032

| title = Skew-T Log-P
| image = skew_t_log_p_2x.png
| imagesize = 569x626px

}}

==Explanation==
{{incomplete|Created by CHATGPT FOR SOME REASON - This needs an explanation. Do NOT delete this tag too soon.}}
The comic is a funny take on a {{w|skew-T log-P diagram}} (the name comes from the temperature (T) lines being skewed at a 45-degree angle, and the pressure (P) lines being logarithmic in scale). These diagrams are mostly used to plot {{w|atmospheric sounding}}s, which are usually made by sending a weather balloon up into the air.

Because the diagrams have a lot of lines on them (isobars, isotherms, adiabats, and mixing ratios, and that's before plotting the actual measurements of temperature and dewpoint temperature), they can be hard to understand if you haven't learned how to. The comic pretends to offer an explanation of how to interpret one such diagram (which may appear to have measurements from two separate weather balloons, one with two solid black lines for its measurements and the other with two dashed black lines, whereas the two lines and various styles of line generally mean different measurements from the same balloon-track), but most of the explanations are blatantly incorrect or humorous in nature.

Tightly packed isobars would indicate stronger winds, which (away from the tropics) would generally be either clockwise or anti-clockwise around the centre of the dominant isobar feature, depending upon whether that's a high pressure or a low pressure and (away from the tropics) which hemisphere.

[[File:Annotated_Skew_T_diagram.png|thumb|An actual Skew-T Log-P diagram, with several real annotations.]]The true design of a Skew-T Log-P diagram is intended to best represent the nature of the weather in any given column of atmosphere. The pressure (vertical axis, with pressure being closely but not directly inversely synonymous to altitude) is shown as a logarithmic scale (i.e. Log-P) due to the more practical separation of values. As height increases, relevent changes in the atmosphere also generally become more spaced out. A linear scale would create a 'busy' area at a lower plot and an effectively featureless upper stretch. The temperature scale is deliberately tilted, rather than orthagonal, which (together with the logarithmic nature of the inverted pressure scale) allows the typical way that temperatures fall with altitude(≈inversely against pressure) to trend roughly vertically, give or take the notable changes that are key to understanding the forecast. Other measurement lines, differently skewed and often also curving across the temperature/pressure skewed-log 'grid', represent various other idealistic relationships (where both T and P vary, keeping another measure constant) that are useful references to meteorologists.

Upon this style of graph are plotted the ''actual'' measurements obtained by (e.g.) releasing a weather balloon. As well as the variation of actual temperatures and pressures, other retrieved data is plotted, such the {{w|dew point}}. The dew point is a function of how the humidity of the air interacts with any given temperature and pressure to produce condensation. By observing how the actual measurements and dew point line converge and cross, the development and nature of clouds can be tracked and pinned to specific cloud layers. Further details may also be included, such as wind-direction and wind-speed indications (often to the side of the plot) to give a visual cue about possible {{w|wind shear}} and/or to suggest which direction of adjacent weather-station readings may hold clues as to what changes may later blow in above the current site.

==Explanation==
{{incomplete|Created by a HIGH-PITCHED HUM GENERATOR THAT WAS LAST MENTIONED EXACTLY 1258 COMICS AGO - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
A {{w|distribution board}}, referred to as a "breaker box" here and also commonly referred to as a "fuse box", "breaker panel", "DB box", and many other names, is a metal box attached to a wall inside a building, usually in some maintenance area, containing several {{w|circuit breakers}} that let power through to various parts of the building. A circuit breaker is an electrical switch, usually in the form of a small lever, that will physically open if too much power is flowing through, as might be the case if a fault occurs, in order to prevent fires and protect appliances.

In most breaker boxes, each individual breaker is labeled to let the operator know what that specific breaker controls. A breaker will usually control something like the outlets or lights in a certain room, or some large appliance.

However, in houses that have been rewired multiple times (or are poorly wired), this can quickly become overcomplicated with seemingly random connections. Randall lives in Boston where much of the housing stock is from the late 1800s or early 1900s, and he is likely to live in a house with non-ideal wiring, which may have inspired this comic.

The comic satirizes these complex wiring setups, with multiple breakers "controlling" arbitrary things, including some that -- in the classic style of XKCD -- may be impossible to hook a breaker up to, getting progressively more absurd to the point of disabling certain laws of physics.

===Table of the breakers labels===
{|class = "wikitable"
! Label next to breaker !! Explanation !! Note
|-
! colspan="3"|Left column of switches
|-
| Kitchen Lights || The lights in the kitchen. || rowspan="3"| Standard items that could be separate
|-
| Living room lights || The lights in the living room.
|-
| Porch lights || The lights on the porch.
|-
| Bathroom lights and one surprise mystery outlet somewhere || The lights in the bathroom, but also a random outlet.
This kind of situation can occur if an electrician – while adding wiring – chooses to wire seemingly logically unrelated things to the same circuit because it's convient/sensible for her to do so. This can mystify future homeowners who don't know the wiring history.
| Standard, but 'kludged'
|-
| North-facing appliances || colspan="2"|Difficult, but not theoretically impossible. Presumably this house has:
#a smart wiring system that knows which outlets control which appliances, and can toggle all outlets,
#all appliances with magnetic compasses that report their orientation to the smart home controler, and
#this breaker is not a simple power on/off but can selectively disable only north-facing appliances.
Alternative explanations:
* The switch may be physically wired only to outlets installed on a southern wall in the property (or ''all'' southern walls, for each room that requires them), with the presumption that everything connected to these exclusively north-facing outlets also faces directly away from the wall(s).
* It could mean the appliances on the north-facing walls of the house.

Note: "North-facing" has broad interpretation, as lax as northeast to northwest or as strict as {{w|Points of the compass#32-wind compass rose|north by east to north by west}}.

|-
| Bathtub drain light || colspan="2"|Bathtub drains typically do not have lights, but this breaker provides power to that and only that. Why it isn't already considered a "bathroom light" is unexplained (unless it's for the bit of the pipe that is ''external'' to that room).
|-
| Appliances whose names contain the letter "F" || colspan="2"|Also difficult but not theoretically impossible. Similar to "North-facing appliances," this would require a smart wiring system that can detect the official names of appliances plugged into each outlet, and the ability of this breaker switch to selectively toggle certain outlets. (Typical electrical systems do not carry data about names, for starters.)
Some common household appliances that this switch might control:
* coffee maker
* refrigerator
* freezer
* fan
* air fryer
* food processor
* waffle iron
* fabric steamer
* fireplace (electric)
|-
| Hot water heater || Usually just a heater that creates (and typically stores) hot water. But given that the next breaker controls the "Regular water heater", this breaker might actually control a water heater that pointlessly heats water that is ''already'' hot.
 This is probably a joke about the fact that the common phrase "hot water heater" is [[technically]] redundant or misleading:
* Redundant because the simpler term "water heater" is enough to describe a device that produces hot water
* Misleading because it's not the purpose of residential water heaters to heat water that is ''already'' hot).
|rowspan="2"|Two "heaters"
|-
| Regular water heater || The heater for regular water. Together with the switch above, this presumes it's for a heater for heating water that is not yet hot (usually called a "hot water heater", hence the joke).
|-
| Outlets in rooms that it's normal to eat pizza in || colspan="2"|This controls every outlet in rooms that it's normal to eat pizza in, such as the dining room and kitchen and – depending on the "normal" habits of the inhabitants – other rooms such as the bedroom, bathroom, or living room (if not already covered by the "living room lights" switch above).
|-
| High-pitched hum generator || colspan="2"|Controls a high-pitched hum generator. This is a call-back to [[1590: The Source]].
|-
| The solution to the cryptogram below: || colspan="2"|Likely a pun on "breaking" or solving a cryptogram, which is a puzzle where a sentence has been encoded using a cipher, usually simple, and the goal is to determine the cipher and recover the original sentence from the encoded one.
Another explanation is that this switch enables or disables the solution somehow, perhaps toggling its knowability or solvability.
|-
| Bugs || colspan="2"|Several interpretations are possible:
* Disable all software bugs in the house*
* Disable all insect bugs in the house – as an efficient form of pest control – perhaps using ultrasonic emitters that drive away bugs. May be a reference to [[2753: Air Handler]].
* Disable power to all covert listening devices, which would be able to be switched off if wired into the house's electrical grid.
* Disable the whole global category of bugs (insects, arachnids, and other small arthropods), in which case we'd have no more pests and we'd reduce disease likes malaria and {{w|Lyme disease}}. Food webs would also collapse, and our world would be overrun with waste.
 <nowiki>*</nowiki>Though it's unlikely that it's what Randall is referring to, computer bugs switches actually exist. It's a feature in some video game emulators to either run an unofficial patched version or to stay true to the original system, for example to allow bug-exploit speedruns of a video game.
|-
! colspan="3"|Right column of switches
|-
| A whirring fan you didn't realize was on until now || colspan="2"|The AC in a building usually creates quiet white noise from fans, which people usually do not hear until they become aware that there is a sound. Other appliances, such as refrigerators or home servers, can have similar effects.
|-
| Dishwasher || colspan="2"|The dishwasher.
|-
| Dishes || colspan="2"|Traditionally, dishes cannot be turned off, as they do not normally require electricity. "Dishes" could be the label for a dishwasher on another house's breaker box, but this one already used that label. Another, unlikely explanation is that this switch controls two or more satellite dishes.
|-
| Hallway lights || The lights in the hallway or hallways. || rowspan="3"|"Hallway" regions
|-
| Hallway outlets || The outlets in the hallway or hallways.
|-
| Hallway floors || This breaker has several potential interpretations:
#A master switch for all floors (storeys) in the building which include hallways, e.g. the guestroom areas in a hotel, whilst possibly excluding the lobby and service levels
#Outlets in the floor
#Electric underfloor heating (heated bathroom floors are a feature in some houses)
#Electrification of the floors -- not common outside of horror and heist movies.
#Disabling all floors entirely, so everything resting on the floors falls through.
|-
| Social media || colspan="2"|This breaker also has several potential interpretations of "turning off social media":
#'Digital detoxes', where someone says "I'm going to turn off my social media" and intends to deny themselves access to all their social media apps.
#A switch for a parent to turn off all social media entering the house to protect their kids and themselves, which references a type of specialized content filter available through Wi-Fi router settings, not traditionally a breaker box.
#A callback to [[908: The Cloud]]. Since most social media platforms are centralized services, it would be theoretically possible to hook up a switch to the main power supply of every server building at once, given some extremely long wires, a breaker capable of handling the abhorrently massive electric load, and agreement from every social media provider([[1439|optional]]).
#The theoretical desire by some to "turn off social media" for the world due to its harmful effects on society. As someone who lived before social media and saw its spread over two decades, Randall may be ruing the impacts of social media on civilization and channeling his desire to put the genie back in the bottle.
|-
| State law || Likely a pun on "State Law Breaker."
Taken literally, it would either disable enforcement of State Law or nullify every single one, creating a state of martial law similar to the premise of the popular movie, "The Purge". It's unclear if this refers to Randall's state of Massachusetts or State Law as a general concept.
| rowspan="2"|"Legal" items
|-
| Federal law || Likely a pun on "Federal Law Breaker," though it could also be taken literally, as above. The ramifications of nullifying every US Federal law are immense. Disabling Federal Law while keeping State Law would theoretically fulfill the goals of the "States Rights" advocates, groups of conservatives across US history aiming to return Federal power to the States.
|-
| Second law of thermodynamics || The Second Law of Thermodynamics, in simple terms, states that the total entropy (or disorder) of an isolated system can only increase over time. It's a fundamental principle that dictates the direction of energy flow and the feasibility of many processes, and provides an arrow of time.
Turning off the second law of thermodynamics would have some pros and cons.
;GOOD STUFF
*'''Perpetual Motion Machines''': Machines that can do work indefinitely without an energy source would become possible, defying our current understanding of energy conservation.
*'''Reversibility of Processes''': Many natural processes that are irreversible under current laws could be reversed. For instance, melted ice could spontaneously turn back into a solid without energy removal.
*'''Recycling Energy''': We could theoretically use the same quantum of energy over and over again, leading to ultra-efficient systems and potentially solving many of the world's energy problems.
*'''Reversing Entropy-Driven Processes''': Things like mixing cream and coffee or ink in water could spontaneously unmix.
;BAD STUFF
*'''End Life as We Know It:''' All living organisms rely on the second law for crucial processes, including metabolism and reproduction. If the second law were negated, life, at least as we understand it, might not be possible.
*'''No Heat Engines:''' Engines rely on the flow of heat from hotter to colder bodies. Without the Second Law, our cars, power plants, refrigerators, and many other devices would not function.
*'''Breakdown of Molecular Processes:''' Molecules spontaneously move from areas of higher to lower concentration due to entropy. Without this, diffusion, osmosis, and many biochemical reactions wouldn't occur as they currently do.
*'''Loss of Directionality:''' One interpretation of the Second Law provides a directionality to time (the so-called "arrow of time"). Without it, causality and our understanding of past, present, and future could be fundamentally altered.
*'''Unpredictable Outcomes:''' Turning off the Second Law could result in a universe where outcomes are not probabilistically predictable. You couldn't rely on anything happening as it "should," leading to chaos in every sense.
 This law of physics was also explored in the What If? article [https://what-if.xkcd.com/145/ Fire From Moonlight].
| rowspan="3"|"Physics" items
|-
| Friction || Friction is the resistive force that opposes the relative motion or tendency of such motion of two surfaces in contact. Turning it off has some upsides and downsides.
;UPSIDES
*'''Perpetual Motion Machines:''' Without friction, once an object starts moving, it would continue indefinitely unless acted upon by another force. This could lead to perpetual motion machines that could generate energy.
*'''Super-Efficient Transport:''' Cars, trains, and other vehicles would glide effortlessly once set into motion, leading to immense energy savings.
*'''Unique Sports:''' New sports and activities would emerge, where players glide or slide over surfaces without friction.
;DOWNSIDES
*'''Walking Would Be Impossible:''' We rely on friction between our feet and the ground to move. Without it, we would be unable to walk, run, or even stand.
*'''No Manual Dexterity:''' Holding, grabbing, or manipulating objects would be impossible. Even simple tasks like holding a glass or writing with a pen would be out of reach.
*'''Catastrophic Mechanical Failures:''' Many machines rely on friction to function. Brakes in cars, for instance, use friction to slow down and stop the vehicle. Without it, uncontrollable accidents would occur.
*'''No Sound:''' Friction between air molecules creates sound waves. Without friction, the world would be silent.
*'''Breathing Difficulties:''' Our respiratory system relies on frictional forces when the alveoli in our lungs exchange oxygen and carbon dioxide with the bloodstream.
*'''No Fire:''' Fire relies on friction for its creation, such as when striking a match. The absence of friction would mean no traditional methods of starting a fire.
*'''Collisions:''' Objects, once set in motion, would continue to move until they hit something, leading to a myriad of unpredictable and uncontrollable collisions.
 Being in a frictionless environment (and a vacuum, as physicists love...) was the subject of [[669: Experiment]].
|-
| Gravity || Gravity is a natural force that attracts two bodies toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.
Turning off gravity would have some advantages and disadvantages.
;ADVANTAGES
* '''Flight''': Without gravity, every leap could turn into a flight. We could push off surfaces and float effortlessly through the air.
* '''No Weight Restrictions''': Large structures could be built without concern for weight-bearing loads. This would drastically change engineering and architectural designs.
* '''New Sports''': Zero-gravity sports and activities could become a reality on Earth. Imagine playing basketball or soccer without gravity!
;DISADVANTAGES
* '''Loss of Atmosphere and Oceans''': Without gravity, Earth's atmosphere would dissipate into space, and water from oceans, rivers, and lakes would float away, making life as we know it impossible.
* '''Unanchored Chaos''': Everything not fixed to the ground, including people, animals, vehicles, and foundationless structures, could become airborne, causing massive destruction and chaos.
* '''Disruption of Celestial Order''': Earth would no longer orbit the Sun, the Moon would drift away rather quickly, and the structural integrity of the universe, including galaxies and solar systems, would be jeopardized.
* '''Everything Exploding''': Most celestial bodies, ranging from the moon to supermassive black holes, would explode from internal pressure and centripetal forces no longer fighting against gravity throwing everything into space.
* '''Aggregation Absence''': Stars, galaxies, and basically anything in space requires gravity to form. Without gravity, no stars, planets, or meteors would form ever again.

Of course, if this switch is turned off, it may simply mean that objects within the house itself are no longer subject to gravity. This would be '''''far''''' less cataclysmic, and as a bonus, this would make it much, much easier to move around the house, get to higher areas, and move objects, but could prove to cause some problems once the breaker is turned back on, especially for the floor.
|-
| Circuit breakers || colspan="2"|If this was turned off, it would presumably turn off the functionality of the circuit breaker itself, if it was wired to include itself. Practically, it would turn of all power in the house since no breaker is supplied or supplying power any more. (Most houses have a main circuit breaker that provides this functionality.) However, because this specifically is a switch for literally circuit breakers and it itself is a circuit breaker, given the other surreal things this breaker box controls, turning it off will possibly make it impossible to turn it on ever again as the switch will no longer function once switched off.

(It might be a perfectly valid label if it refers to multiple subsidiary 'boxes', cascaded off this particular one, each containing one or more additional breakers for convenience or safety. e.g. units dedicated to a shed, garage or workshop room which save the need to traipse all the way to this box's utility cupboard location in the event of an otherwise easily resolved power issue.)

Moreover, if this circuit breaker disables all circuit breakers everywhere, it would result in global infrastructure collapse, halting essential services, including transportation, healthcare, and communication, and leading to widespread chaos.
|-
! colspan="3"|Title text
|-
| colspan="3"|The title text is about causality, arguably another level above the "Physics" switches, and how to use this (unseen) breaker along with the either the last shown switch or another unseen 'meta level' switch that (de)powers the illustrated box.

Turning off the circuit breaker using the CIRCUIT BREAKER switch may lead to a loop, if the disabled breaker can no longer disable itself, leading to it turning back on, etc. Alternatively, turning off the CIRCUIT BREAKER switch might be a one-way street.

Turning the CAUSALITY switch from OFF back to ON might be unlikely to do anything if the circuit breakers upstream of it have been fully deactivated. The separation of cause and effect would ostensibly take precedence over the current switch setting. Turning off CAUSALITY first would prevent either the loop or the permanent disabling of circuit breakers, but would also have many other side effects, including letting switches potentially serve power even if there is no power being served ''to them'', or even spontaneously switching (on or off) without any intervention or reason.

Whether or not turning off causality would actually turn off causality if causality is turned off is an exercise for the reader.

{{incomplete|Created by A 50/50 BLEND OF LITHOSPHERE AND CRUST - Please change this comment when editing this page. Like this? Do NOT delete this tag too soon.}}

This comic reimagines the internal structure of the earth, mixing the real geological layers of the planet with fictional ones. Some of the fictional layers are appropriated from the layers of other objects that have cross-sectional diagrams, such as the layers of a piece of fruit, an eyeball, an item of confectionary or a building.

{| class="wikitable"
! Layer
! scope="col"| Explanation
|-
! scope="row"| Lithosphere/Crust (50/50 Blend)
| The {{w|lithosphere}} is any outermost rocky layer of a planet. On Earth it consists of the {{w|Earth's crust|crust}} and any parts of the upper mantle (see below) that do not convect. To say they are two distinct layers that could be blended together is rather nonsensical.
The upper limit of a planet's lithosphere is usually taken as where it meets the hydrosphere/atmosphere (wherever either may be present, otherwise the vacuum of space) but may or may not include the rock-derived {{w|pedosphere}} (for Earth, especially) or distinct overburden of loose {{w|regolith}}. All of these overlaid layers would typically be far too thin to be reliably distinct in the depiction of this Earth-like planet, and the diagram depicts the surface details only as a 'painted on' blue/greens/browns/etc to distinguish ocean areas and land heights with vertical depths/elevations that are already effectively insignificant at the scale of this diagram, before even considering the such relatively narrow layers of interface material.
|-
! scope="row"| {{w|Upper mantle}}
| An actual layer of the earth's structure.
|-
! scope="row"| Deep mantle
| A pseudo-correct layer of the earth's structure. There is a layer called the {{w|lower mantle}}, which could be what Randall refers to.
|-
! scope="row"| Filler
| This suggests there is space in the earth that was empty, so the creator(s) added some filler to fill up the extra space.
|-
! scope="row"| Vitreous humor
|Vitreous humor ({{w|vitreous body}}) is the transparent gel inside the eye, located between the lens and the retina.
|-
! scope="row"| Mechanical/HVAC layer
| {{w|HVAC}} is an abbreviation for 'Heating, Ventilation and Air Conditioning' - the system used to heat or cool a building. Tall buildings may have a dedicated "HVAC floor" or "{{w|mechanical floor}}" between regular floors, like an extra layer.
|-
! scope="row"| Guacamole
| {{w|Guacamole}} is a dip or sauce made from avocados. [https://www.britannica.com/topic/guacamole Originating from ancient Mexico], it often includes onions, tomatoes and spices. Notably, guacamole is a major component of seven layer dip, and is shown here to be the seventh layer (from the surface).
|-
! scope="row"| Cytoplasm
|{{w|Cytoplasm}} is the "flesh" of both eukaryotic and prokaryotic cells; a jelly-like substance that fills all the otherwise empty space within the cell.
|-
! scope="row"| Cork
|Due to the proximity of the cork layer and the insulation layer, this may possibly be referencing {{w|Cork (material)|cork}}-lined walls, which are used today mostly for high quality soundproofing, but have [https://www.jstor.org/stable/27135713 a considerable history]. Another potential reference could be the fact that baseballs (another spherical shape) have a layer of cork in them (though it is usually in the center). Finally, the cork is a real layer of tissue in many woody plants, part of the bark. This comic was posted the day after Birkenstock Holding plc was listed on the New York Stock Exchange; Birkenstock sandals include a layer of cork.
|-
! scope="row"| Insulation
|Possibly a reference to the {{w|building insulation}} installed in the walls and ceilings of buildings. Technical fabrics used to make clothing also often include an insulation layer, combined with, for example, a waterproof/water-resistant membrane and an inner contact later.
|-
! scope="row"| Seeds
|Part of a fruit which often appear in a distinct layer within, or sometimes on the surface of, the flesh.
|-
! scope="row"| {{w|Pith}}
|Part of a tree trunk or the thick spongy layer of the skin of a citrus fruit. Notably, this layer is below Seeds, which implies the seeds are outside of the pith. Although rare, some fruits do, in fact, have their seeds on the outside of their skin, such as {{w|Cashews}}. However, this is not present in any well-known citrus plants, or, if there are citrus plants like this, they are not discovered yet, let alone well-documented.
|-
! scope="row"| Nougat
|{{w|Nougat}} is a family of confections made with sugar or honey, roasted nuts, whipped egg whites and, sometimes, chopped candied fruit. It often appears as layers within confectionary items (such as Snickers, Double Decker and Mars) and, notably in relation to the comic, it constitutes the second-innermost layer of {{w|Mozartkugel}}n, a spherical confection.
Geography teachers sometimes hand confectionery like this to their students to give them an idea what "concentrically layered structure" means. Most of the time it turns out that this is their least concern, while at the same time a general consensus emerges that this is one of the best ideas said teacher has had in a long time. This layer is possibly an allusion to that practice.
|-
! scope="row"| {{w|Outer core}}
| An actual layer of the earth's structure.
|-
! scope="row"| {{w|Inner core}}
| An actual layer of the earth's structure.
|-
! scope="row"| Secret core
| Likely references secret compartments that may be hidden in the hardest to find recesses of other objects or structures, for the purposes of concealing precious items or closely-guarded secrets. Could also be interpreted as a section of the core that only certain people, such as Randall, are aware of. In the context of "inner core, outer core, secret core" may also be a riff on Leonard Cohen's ''Hallelujah'', a la [[2583: Chorded Keyboard]].
|-
! scope="row"| Kinder toy capsule
| A {{w|Kinder (brand)|Kinder}} toy is a reference to a chocolate egg-shaped confection by the Kinder brand, the {{w|Kinder Surprise}}, a chocolate shell with a plastic 'yolk' capsule in the center. Though that is loose within a void, unlike this 'Earth model', it closely matches this philosophy despite (or because of) being a {{w|Kinder_Surprise#United_States|banned food item}} in the United States, due to a 1938 FDA rule prohibiting a "non-nutritive object" (the plastic egg 'yolk' containing the toy) to be encased inside of an edible item (the outer chocolate layer) unless it has a specific function related to the edible part. It is widely believed that this is because the 'yolk' can be a choking hazard, despite the fact that you'd have to be swallowing a chicken egg-sized confectionery in a single mouthful for that to happen accidentally, or deliberately try to consume the plastic capsule whole. The toys within, however, may contain small pieces that can pose a choking hazard, especially in the toys that are packed as components, requiring some assembly, in order to fit into the capsule. Rules about small components (in toys for young children) and the inclusion of non-food contents within food-items have been used to prohibit this product within the US. To specifically overcome the latter regulations, the {{w|Kinder Joy}} was developed; an egg-shaped packaging containing the chocolate treat in one half and the toy separately within the other.

Randall's punchline of the comic is that there may indeed be a hidden toy at the center of the Earth. The title text explains that due to the {{w|Earth's magnetic field|geomagnetic field}} not behaving as scientific models suggest it should, some geophysicists argue that the hidden toy is – or at least contains – some additional form of magnet which impacts the accepted {{w|Magnetohydrodynamics|magnetohydrodynamic}} effect. A more plausible explanation is that their model is wrong because they've based it on Randall's diagram full of spurious layers!
|}

Since the radius of the earth is 6371 km, if the diagram is to scale then measurement of it gives the Kinder Toy Capsule a radius of about 900 km. This gives the Kinder Toy Capsule a volume of just over 3 billion km3. Assuming a real Kinder Egg has a volume of 60 cm3, and a packing density of 63.5%, the Kinder Toy Capsule could contain 5x1022 (50 sextillion) actual Kinder Eggs. Current mathematical models of the magnetohydrodynamics of the Earth's core do not include the potentially significant contribution of 50 sextillion Kinder Toy Capsules,{{citation needed}} a glaring oversight in a well developed field.

Talk:2838: Dubious Islands

2023-10-07T16:14:33Z

141.101.99.163: Failed to close my link-bracket.

As a native of the North Country of Northern New York, I'm really disappointed that Randall didn't label the St. Lawrence river. :-( [[Special:Contributions/162.158.158.253|162.158.158.253]] 22:49, 6 October 2023 (UTC)

Had a go at the Transcript. Plenty of problems with it, but I was attempting to be partway methodical (generally heading north-to-south, seemed easier than "north-and clockwise" or any other sweep, once I started to do it) and not actually mention 'quoted' words more than once. Unless they're actually written multiple times. (looking at you, Mississippi!) 
But had no option but to repeat some of the quoted text ''within'' the label-descriptor 'tags', perhaps each actual fragment should indeed by given ''all'' boundaries, but I think that's better left for the table that will inevitably have to be put into the main Explanation. There one can actually list the named ''and unnamed'' bordering waters (river, canal, lake, sea and ocean) for actual reference. 
Also the wording. Tried not to repeat "bounded by" synonyms too much, but maybe I should just have chosen one option and repeated it anyway, given the difficulties and contextual issues of doing it absolutely unrepeatably. But it's my best try (at just gone midnight, indicating how personally familiar I might be with the continental US's geography, or not). And thus over to you people who actually know more about the Mississippi than merely how to spell it. (Not sure I've read, and thus spelt, some of the other names given right, either. Definitely check and edit as necessary.) Perhaps a geographic map could (e.g.) even identify the "Nunavuk+" territory with a better actually known descriptor, too! Canada is even less my forté than the US. [[Special:Contributions/162.158.74.63|162.158.74.63]] 23:50, 6 October 2023 (UTC)

Im shocked that Randall conflated the hudson and Champlain when the two dont connect, missing each other by a slim margin.

Southern NJ is made an island by the Delaware River, the Delaware and Raritan canal and the Raritan river. -- [[User:162.158.158.98|162.158.158.98]] ([[User talk:162.158.158.98|talk]]) 03:06, 7 October 2023 (UTC) ''(please sign your comments with <nowiki>~~</nowiki>~~)''

I came to this comic hoping to learn the names of the islands, and then to the explanation hoping they were present but hidden in some way. Irrational! [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 07:43, 7 October 2023 (UTC)

;Where is Long Island?
Oh! Wait. The map only shows _dubious_ islands. {{unsigned ip|172.70.38.72|06:28, 7 October 2023}}
:All actual islands (Hawaii, the myriad of ones in the Canadian arctic, etc) are not there, so I take it as read that this is the contiguous mainland continental North America (stopping at the Panama cut) with divided by all cross-waterways of any significance. i.e. major rivers, hence why no lichen-like tributary 'fan' incursions into these areas; major canals, which means massive irrigation projects (and any actual ship-navigable ones, I presume) or else ever ditch or drain would count, lakes of course (but there's a lot of lakes in the Canadian north that are not shown, let alone used as might be hydrodynamically linked).
:Compared with [https://upload.wikimedia.org/wikipedia/commons/9/90/Map_of_canals_of_the_United_Kingdom.png what Great Britain might look like], so subdivided, it looks positively restrained. I mean, you can probably remove all those with dead-ends to make the 'disconnection map' simpler. And, in today's age, all stretches that are no longer viable/continuous/navigable for various reasons like railways and major roads being slapped over/next to them and rendering them obsolete/uncared-for/etc, but that still leaves quite a lot of [https://upload.wikimedia.org/wikipedia/commons/0/07/England_Wales_Waterway_Map_Simplified.svg islands], such the cut(s, several!) between Thames and Severn, the Humber to various Lancashire 'outlets', etc. And that link doesn't even show the Caledonian Canal cross (alongside/within the Great Glen), the more southerly Forth And Clyde route, etc. [[Special:Contributions/141.101.98.19|141.101.98.19]] 16:08, 7 October 2023 (UTC)

Its worth pointing out the comic was drawn in 2006 -- 'pretty gay' was not nearly as politically incorrect then as it is now. Wow, this is an old comic. [[Special:Contributions/162.158.255.125|162.158.255.125]] 14:33, 8 September 2015 (UTC)

Political incorrectness is a good thing. I'd hope he'd do this one again today. — [[User:Kazvorpal|Kazvorpal]] ([[User talk:Kazvorpal|talk]]) 01:07, 24 April 2019 (UTC)
:Political incorrectness is a good thing? wow. While I also find overly political correctness in many cases over the top, unneccesary and annoying, this is a clear example where political correctness helps to battle discrimination. By using the term "gay" to describe one stereotype associated with homosexuality, this stereotype is further enforced, and people are treated according to it. I do not know a lot about you, but your username sounds like an adjective, so imagine, I started a trend describing people who are e.g. pedophile as "kazvorpal", and this trend catches on. Soon you would find yourself excluded from events, jobs, etc. because people would assume you are a pedophile. Wouldn't you prefer that to not happen? that is one example why political correctness is a good thing. Sorry for the trollfeeding. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 06:04, 24 April 2019 (UTC)
::No, you are suffering from the ravages of inductive reasoning. Political correctness includes a pretense that the speaker is battling discrimination, but it's just virtue signalling. They are, in fact, ''encouraging'' discrimination, and heaping advocacy of censorship and repression on top of it. Using "gay" as a mock pejorative does nothing to harm actual homosexuals, and in fact robs the term of its emotional power, as humor often does. Daniel Tosh incessantly making faux-bigoted comments uses humor to weaken racism, sexism, et cetera. And the end does not justify the means: Repressing the expression of others is evil, even when you're trying to use doing so to impress others about how virtuous you are. — [[User:Kazvorpal|Kazvorpal]] ([[User talk:Kazvorpal|talk]]) 15:43, 29 October 2019 (UTC)

During the COVID-19 pandemic, there was a significant shift from in-person to computer-mediated interactions for both recreational and professional activities. For many, the computer setup used for these interactions is a laptop with a webcam above the screen. As people have become accustomed to looking directly into the camera, i.e. above where the other people's faces are, to simulate eye contact for meetings, Randall implies that there will be issues returning to pre-COVID life. In response, he has designed a baseball cap with an image that resembles a laptop webcam that sits above the wearer's eyes and a message that humorously acknowledges that the reader is likely reverting to virtual meeting habits for in-person interactions and that reminds people that for in-person interactions, one must look the other person's face, not above it like there's a webcam there.

The apparent tendency for the heterosexual male's gaze to gravitate down towards the covered breasts of women they may be talking to is famously lampshaded by ladies' T-shirts with writing such as "Hey! My eyes are up there!" and an arrow. Though its effect may be diluted by the {{w|Saccade|saccadic movements}} that also draw focus towards words that 'demand to be read' (it may even be the intent from at least some of those wearing these garments), which may also be an issue in the case of this hat. For added irony, one could perhaps fit an actual active camera module within the body of the hat seeing the world through a pinhole in the 'fake' camera image.

Actual shirt-based text (as in the Title Text) would represent where a video-conferencer is ''not'' staring at the screen-top camera to 'fake' eye contact on the other screen(s) but truly aimed at the image of the eyes. The view of such an 'honest' stare could look like a 'chest gaze'.

1673: Timeline of Bicycle Design

2021-01-08T10:54:46Z

141.101.99.163: /* Bike Design Analysis */ The skateboard bike doesn't even have an axle!

{{comic
| number = 1673
| date = April 27, 2016
| title = Timeline of Bicycle Design
| image = timeline of bicycle design.png
| titletext = I'll be honest--the 1950s were a rough time for cycling.
}}

==Explanation==
[[Randall]] created what is supposedly a 200 year history for bicycles with 13 designs ranging from 1810 to 2016. However, a cursory glance at each one shows that they are almost all fictitious, heavily flawed, and most don't even fit the definition of "bicycle". The main point of the comic is to show off these silly joke designs.

The only model that both looks like a real model and fits the year is the 1875 model, which resembles the {{w|Penny-farthing}}. The Penny-farthing was popular in the 1870s until the {{w|Safety bicycle}} took over around 1880. The 1875 model appears to be missing handlebars, but it's worth noting that on the real bicycle, the handlebars were very small and close to the saddle, and may be too small to appear in the drawing.

The 1860 model looks like the {{w|American Star Bicycle}}, but that bicycle was first invented in the 1880s.

The 1900 model looks like one of {{w|Paul Scheerbart}} 's perpetual motion machines.

Some of the other examples of "bikes" could, however, look like those in the image at the top of the {{w|Velocipede}} Wikipedia page.

Several of the "bikes" are shown with a human — [[Ponytail]] is "riding" the pole-vaulting bike, [[Cueball]] appears in four designs, and [[Megan]] appears in three. These humans provide a sense of scale and, in some cases, a demonstration of how the bike might be operated. Cueball's appearance in the 1900 design shows how huge that bike is, appearing to dwarf the previous two models while continuing the short trend of ever-increasing size.

Only two of the bikes have pedals (1875 and 2016) and another two have a sprocket with a chain (1900 and 1980). Seven designs include a seat for the rider — eight if you count the device holding Megan in the 1980 model.

The 1925 model is reminiscent of a {{w|fractal}}; {{w|Benoit Mandelbrot}} was born in October 1924.

The 1880 model could be the result of an {{w|evolutionary algorithm}} trying to produce a bicycle. Some sub-optimal algorithms that have been given the task of creating a vehicle have been shown to misplace parts in ways that makes them completely useless and/or inaccessible — for example, placing a small wheel inside a much larger wheel.

This comic (especially the 2016 bicycle) is possibly also a reference to [https://www.liverpool.ac.uk/~rlawson/cycleweb.html The Science of Cycology], a cognitive psychology project run by Rebecca Lawson at the University of Liverpool, which asked study participants to draw a bicycle from memory. The error rate was high, supporting a hypothesis that humans over-estimate their ability to explain how things work. Gianluca Gimini ran a similar project, [http://www.gianlucagimini.it/prototypes/velocipedia.html Velocipedia], in which he asked people to draw free-hand sketches of bicycles from memory, then later rendered some of the results as if they were real bikes.

Also, the designs given for the years from 1825 to 1925 distinctly resemble designs that tend to evolve in the various challenge environments in the genetic evolution games [http://boxcar2d.com/ BoxCar2D] ({{w|Flash Player}}) or [http://rednuht.org/genetic_cars_2/ Genetic Cars 2] ({{w|HTML5}}).

The 1980 design looks strikingly similar to the ''South Park'' "wild whacky action bike".

The title text refers to the scene labeled "1955" which depicts Cueball being chased by 3 bicycle wheels. Whatever caused the wheels to chase Cueball down a hill is left to the reader's imagination. It could be that the wheels have become sentient and are actively chasing Cueball, or it could be that the bicycle failed horribly and Cueball is running from the wreckage. The era this "bike design" is from (1955, which is in the 50s) would be hard to ride a bike in if it was the only available design.

|-
| 1810
| [[File:1673-_1810.png|310px]]
| A single wheel with a long curved bar. Ponytail is riding it like a pole vault.
| {{w|Unicycle}}, {{w|Pole vault}}
| There is no means to propel it once started, since the rider is held off the ground. It would be very difficult to balance on this device as well.
|-
| 1825
| [[File:1673-_1825.png|310px]]
| A large wheel connected to a tiny one, with a complex bar leading to a set of handlebars. Cueball is pushing it from behind.
| {{w|Wheelbarrow}}
| This bike has no seat and no means of propulsion other than being pushed from behind, defeating its purpose as a vehicle.
|-
| 1840
| [[File:1673-_1840.png|310px]]
| Two wheels connected by a single horizontal bar.
| {{w|Skateboard}}
| No means of propulsion or steering. Design is bottom-heavy, making it very difficult to keep balance. The wheels also seem to be welded to the bike, rendering it completely useless.
|-
| 1860
| [[File:1673-_1860.png|310px]]
| A large wheel in back and a small wheel in front, connected to a large seat on top. Megan is sitting on the seat doing nothing.
| {{w|Pennyfarthing}} (backwards),American Star bicycle
| No means of propulsion or steering.
|-
| 1875
| [[File:1673-_1875.png|310px]]
| A large wheel in front with pedals attached, connected by a nearly-vertical rod to a small seat on top. A curved rod connects the seat to a much smaller wheel.
| Pennyfarthing (almost exact match)
| No handlebars are depicted, suggesting that there is no means of steering.
|-
| 1880
| [[File:1673-_1880.png|310px]]
| A very large wheel, connected by a short rod to a much smaller wheel and a seat. These hang from the axle at an odd angle.
| Unicycle (vague)
| The seat and small wheel appear to hang inside or next to the large wheel. A rider could not sit on the seat and would be unable to touch the ground, making it impossible to propel or control the bike.
|-
| 1900
| [[File:1673-_1900.png|310px]]
| An extremely large wheel, connected by a chain to a roughly human-sized wheel on top. Cueball may be standing on it, but it's unclear what he's doing. He appears to be pushing a giant ball or a very big globe.
| Unicycle
| No means of steering, unclear means of propulsion. It would be very difficult to mount this device, to get it moving with human power, and to control and stop it. Additionally, it would require many resources to build and a building several stories tall to store it.
|-
| 1915
| [[File:1673-_1915.png|310px]]
| A large wheel connected by an angled rod to a seat. The seat is connected by a nearly-vertical rod to an extremely small wheel behind the large one. Cueball is sitting on the seat, leaning far forward and apparently turning the large wheel by hand.
| Pennyfarthing, {{w|Wheelchair}}
| No apparent means of steering. Propulsion appears to be by hand, similar to a manual wheelchair, making the device both impractical and uncomfortable.
|-
| 1925
| [[File:1673-_1925.png|310px]]
| A symmetric seat sits atop a vertical rod connected to a wheel. From the center of this wheel, the frame extends out both front and back toward the ground, with progressively smaller wheels attached in a fractal design. It appears that only the wheels at the very ends of the rods touch the ground.
| Unicycle, {{w|Fractal}}, Holman Locomotive
| No means of propulsion or steering other than pushing against the ground. Only the tiniest wheels touch the ground - if these are truly in fractal pattern, they would not withstand the weight of a rider nor be able to roll on anything but the smoothest of surfaces.
|-
| 1940
| [[File:1673-_1940.png|310px]]
| A single seat is connected to four small wheels in a line. Each rod is separate, and the wheels are not directly attached to one another. Megan is standing on the seat and pushing the device forward with a long, flexible pole.
| {{w|In-line Skate}}, {{w|Gondola}}
| No means of steering or propulsion (using a pole doesn't count). Frame would very likely collapse under a rider's weight.
|-
| 1955
| [[File:1673-_1955.png|310px]]
| Cueball is being chased down a hill by three {{w|bicycle wheel|bicycle wheels}}.
| ''n/a''
| This scene suggests a spectacular failure of one or more bicycles, resulting in three wheels rolling down a hill. It's also possible the wheels became sentient and are rebelling against humans.
|-
| 1980
| [[File:1673-_1980.png|310px]]
| A wheel is connected to a triangular frame. Extending up from the frame appears to be a back rest. Just in front of the triangle is a sprocket with no pedals. Two long bars connect from here to a front bar, which extends down to a second wheel and up to a very long set of handlebars. The sprocket connects to the front wheel. Megan is crouched on top of the sprocket with her back resting against the rear frame.
| "Chopper" {{w|Motorcycle}}, Women's {{w|Safety bicycle}}
| No apparent means of propulsion unless the sprocket acts like a {{w|cog wheel}}, requiring the rider to essentially run in place to propel the bike, which would be difficult and uncomfortable in Megan's position. While this is the first of the designs that shows a clear means of steering, the chain would interfere.
|-
| 2016
| [[File:1673-_2016.png|310px]]
| A rear wheel has pedals directly attached to it, and is connected to a horizontal rod. A small fender is attached to this rod under the wheel and almost against the ground. A {{w|kickstand}} hangs down and forward. A triangular frame extends upward toward the front, holding a milk bottle, and a second triangle connects to the front wheel, which also has pedals and a low-hanging fender. A set of touring-style handlebars is attached to the front. Two bars extend backward from the two triangles, and a horizontal bar extends backward. Just above the rear wheel, a seat is suspended inside a forked frame hanging down from the top bar.
| Safety bicycle
| The frame is over-complicated and, despite several strong supports in the front, would still likely collapse under a rider's weight. Front pedals would be nearly impossible to use. Seat cannot be used. Fenders and kickstand could easily strike the ground and interfere with the bike's movement.

:[A regular drawing of a Penny-farthing with very small back wheel (half the size of the front wheel on the 1860 bike) and very large front wheel (larger than the 1860 bike) and pedals in the middle of the front wheel. There are no visible handlebars.]
:1875

:[A huge wheel twice the size of the one on the Penny-farthing, and then a small wheel (like the small one on the Penny-farthing) hangs in a rod from the center of the giant wheel. The small wheel has a saddle attached, but it is not straight up.]
:1880

:[This is the largest bike. Not the largest drawings, but where the other have the characters in roughly the same size, this one has a small drawing of Cueball standing on top of the wheel holding on to some kind of handle bar. The wheel is about three times his height.]
:1900

:[Cueball sits in the "saddle" of a bike design that is similar to the Penny-farthing, but the saddle is more a rod, and the back wheel is on a rod going straight down from where the saddle ends. Also there are no pedals, so Cueball seems to be directly spinning the front wheel by hand.]
:1915

:[A symmetrical saddle sits on top of single bike wheel, as with a unicycle but with no pedals. There are (at least) six progressively smaller wheels in-line to the first, three to front and three to the rear, each new wheel approximately half the size of the one before. A possible fourth wheel, presumed to complete the set of medial stabilisers, can no longer be discerned from the rod that goes through the center of the larger wheels.]
:1925

:[Megan stands on top of a saddle that has four individual rods extending from it, each to a small wheel. One wheel is directly beneath her, one is behind her, one is the same distance in front, and one is farther out in front. Megan is pushing the bike with a long flexible rod resembling a pole vault.]
:1940

:[Cueball is running down a steep hill with his arms up, being chased by three normal-sized bike wheels.]
:1955

:[Megan sits on a bike contraption that seems to have a holder around her mid section rather than her sitting on a saddle. This holder goes to the back wheel below her, and there is actually a sprocket with a chain, although no clear pedals beneath her feet. She holds on to a very long handle bar, which connects with two long rods coming from the sprocket at the front end of the bike far ahead of Megan, below which is a wheel, to where the chain is actually going. Both wheels seem to be normal size.]
:1980

:[Another weird contraption of a bike with pedals on both normal sized wheels which have handlebars on the side pointing down towards the front. The saddle hangs in a swing, connected to a rod above it, which goes to the front of the bike and splits in two rods which connect to the center frame of the bike. In front of these there is a contraption resembling many styles of touring bike handlebars, which sits just above the front wheel. The two wheels are connected with a long rod between the center of the wheels and in the middle of this is the center part of the frame going up toward the handle. On the middle of this is a bottle with a label. Towards the back wheel there are two rods sticking out, one presumably a kickstand, the other possibly a parking brake.]

==Explanation==
Beret Guy's phone is about to "die". Cueball assumes this just means that the battery is running out and it needs to be recharged, but the phone in question appears to "die" in a way analogous to the {{w|Stellar_evolution|life and death}} of a star: expending its fuel while heating up and expanding before ultimately losing its outer layers and becoming a white dwarf or similar "lesser" star. However, this is something phones usually don't do.{{Citation needed}}

Stars constantly undergo fusion reactions. The pressure generated by these reactions counteracts gravity, preventing it from collapsing the star during its main lifespan. As the hydrogen mostly fuses into helium in the core, the core gradually becomes more dense and the region of fusion gradually moves away from the center. Then, the star grows in size, reaching the stage of a Red Giant. When most of the "fuel" for fusion has been consumed, gravity will collapse the star into a white dwarf while the outer layers are shed. For stars much more massive than the Sun, there will be a {{w|Supernova|supernova}} explosion caused by a violent collapse, which is [https://what-if.xkcd.com/73/ very powerful]. Heavier stars have shorter lifespans while producing more energy; Beret Guy probably references this when he refuses the charger.

Both a supernova explosion and the collapse of red giants into white dwarfs shed their outer layers, which is referenced in the title text. Once extra mass is added to the dying star, analogous to "charging", the process only accelerates. The phone seems to have a certain mass because [[Beret Guy]] expects it to go (super)nova. Charging the phone may lead to a {{w|Nova|type 1a nova}}.

The comic also plays on the release of two new {{w|IPhone|iPhone models}} with {{w|IPhone_6|bigger}} screens, planned for 2 days after the release of the comic.

The comic could be also explained by the characteristics of Li-ion batteries, which are used in most cellphones. At the end of their useful life, these batteries grow a bit{{fact}}. In case of severe physical or thermal damage or multiple electrical failures, this type of battery can indeed overheat, leading to a run-away thermal reaction inside. That would result in the battery growing{{fact}} and eventually exploding. Connecting a charger to a battery failing in this manner would probably make the process faster [http://batteryuniversity.com/learn/article/safety_concerns_with_li_ion].

The title text mentions PalmPilot, an early mobile device (but not phone), calculator, one of the commonly used functions of a smart phone, and two-way pager, a device for sending and receiving short text messages. This is a reference to how some particles and atoms decay by breaking into smaller, more elementary particles (humorously implying that the three devices are the more elementary components that make up an iPhone).

==Transcript==
[Beret Guy walks on-panel, carrying a smartphone.]
: Beret Guy: My phone's about to die.
[The phone is now subtly larger.]
: Cueball: Where'd you get a big iPhone? I didn't think they were out yet.
: Beret Guy: It's my regular one. It's just dying.
[The phone increases in size again. Beret Guy now holds it in both hands.]
: Beret Guy: As it consumes its battery, it heats up and expands. Soon it will swell to enormous size, engulfing us both.
[The phone is now the size of Beret Guy's torso; he is clutching it to himself. Cueball is pointing off-panel]
: Beret Guy: Then it will collapse in a violent explosion!
: Cueball: ...do you want to borrow my charger?
: Beret Guy: That would only make it run out ''faster''!

1335: Now

==Explanation==
{{incomplete|I've never created a page for a new comic before, so there are many things to fix. Like the transcript.}}

The picture rotates every 15 minutes with the Earth, showing which regions are currently at which times of day, ignoring {{w|Summer Time}} (aka Daylight-Saving Time) and local variations in {{w|Time Zone}}s. However, the cities and countries listed in the picture follow these local variations.

Every 15 minutes (so far, and presumably forever), the image changes. The names used for the image files refer not to {{w|Universal Time}} as one might expect but rather to the time exactly 12 hours off of that. The picture change seems to happen half-way through a 15-minute time increment (so at 7½ minutes after the hour, then 22½ minutes, then 37½, 52½, and repeating), so that the picture is always correct for the nearest multiple of 15 minutes.

When first posted, the picture was exactly 12 hours off. The name of the image file linked from the page matched Universal Time, rather than being 12 hours off as explained above. Somewhere around 5:10 UTC, this was fixed.

==Explanation==
{{incomplete|Incomplete.}}
This comic shows a number of common events, arranged in a grid. Each of the events flashes with their average frequency.

For example, statistically a child is born somewhere on the world approximately every 0.24 seconds, or four times per second. Therefore the tile "One birth" blinks about 4 times per second.

The table below lists all the events and their duration / frequency. Some events make reference to other comics.

The title text refers to the {{w|Pitch drop experiment}} which measures the flow of a piece of pitch over many years. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop. The title text jokes that Randall tried to include a tile that flashes about once every {{w|decade|ten years}}, but the tiles are all {{w|Animated GIF|animated GIFs}} and while the file format supports animations of any length, the resulting file would be too big (at least 10 megabytes).

This particular frequency is taken from:
* The number of persons called {{w|Amelia_(given_name)|Amelia}} ([http://howmanyofme.com/ est. 82,572 people in the U.S.])
* The number of persons born between November 22nd and December 22nd under the astrological sign of {{w|Sagittarius (astrology)|Sagittarius}} (~1/12th of the population, i.e. approximately 6881 Amelias in the U.S.)
* The frequency of soda (soft drinks) being drunk (216 liters per person per year in the U.S.[http://www.nationmaster.com/graph/foo_sof_dri_con-food-soft-drink-consumption]).
According to our figures, 6881 Amelias drink 1,44 million liters of soft drinks per year in the United States alone, which means that Randall's figures only account for American Amelias (drinking 356 cc or 12 fl. oz. of soda in each drink).

==Explanation==
{{incomplete|Incomplete.}}
This comic shows a number of common events, arranged in a grid. Each of the events flashes with their average frequency.

For example, statistically a child is born somewhere on the world approximately every 0.24 seconds, or four times per second. Therefore the tile "One birth" blinks about 4 times per second.

The table below lists all the events and their duration / frequency. Some events make reference to other comics.

The title text refers to the {{w|Pitch drop experiment}} which measures the flow of a piece of pitch over many years. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop. The title text jokes that Randall tried to include a tile that flashes about once every {{w|decade|ten years}}, but the tiles are all {{w|Animated GIF|animated GIFs}} and while the file format supports animations of any length, the resulting file would be too big (at least 10 megabytes).

|A Sagittarius named Amelia drinks a soda||style="text-align:right;"|7.79||style="text-align:right;"|7.7||style="text-align:right;"|4,000,000||Randall Munroe is a [http://blog.xkcd.com/2014/01/31/the-baby-name-wizard/ fan of The Baby Name Wizard] blog and its [http://www.babynamewizard.com Name Voyager] tool which shows that "[http://www.babynamewizard.com/baby-name/girl/amelia Amelia]" has recently exploded in popularity. 
This particular frequency is taken from:
* The number of persons called {{w|Amelia_(given_name)|Amelia}} ([http://howmanyofme.com/ est. 82,572 people in the U.S.])
* The number of persons born between November 22nd and December 22nd under the astrological sign of {{w|Sagittarius (astrology)|Sagittarius}} (~1/12th of the population, i.e. approximately 6881 Amelias in the U.S.)
* The frequency of soda (soft drinks) being drunk (216 liters per person per year in the U.S.[http://www.nationmaster.com/graph/foo_sof_dri_con-food-soft-drink-consumption]).
According to our figures, 6881 Amelias drink 1,44 million liters of soft drinks per year in the United States alone, which means that Randall's figures only account for American Amelias (drinking 356 cc or 12 fl. oz. of soda in each drink).

1331: Frequency

2014-02-17T10:44:06Z

141.101.99.163: /* Transcript */ wikified

{{comic
| number = 1331
| date = February 17, 2014

}}

Today's comic is animated. While we prepare a gif for the wiki, click on the date above the comic to see the animated version.
==Explanation==
{{incomplete|Incomplete.}}
This comic shows a number of common events, ordered in a grid. Each of the events flashes with their average frequency.

For example, statistically a child is born somewhere on the world approximately every 0.24 seconds, or five times per second. Therefore the tile "One birth" blinks about 5 times per second.

The table below lists all the events and their duration / frequency. Some events make reference to other comics.

The title text refers to the {{w|Pitch drop experiment}} which measures the flow of a piece of pitch over many years. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop. The title text jokes that Randall tried to include a tile that flashes about once every {{w|decade|ten years}}, but the tiles are all {{w|Animated GIF|animated GIFs}} and the file format does not support animations that long.
