&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a Big Bird. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&amp;quot;Big industry&amp;quot; is a common nickname used to describe monopolistic or near-monopolistic practices in the United States. To be &amp;quot;in someone's pocket&amp;quot; means to be taking bribes, or to be influenced by lobbyists or grant money.&lt;br /&gt;
&lt;br /&gt;
Of the 8 industries listed, {{w|Big Tobacco}} and {{w|Big Pharma}} are nicknames that are commonly used. The mining industry is generally referred to in this context by sector, as {{w|Big Coal}} or {{w|Big Oil}}. The U.S. automobile industry was until recent decades referred to as &amp;quot;Detroit,&amp;quot; later meaning only the {{w|Big Three automobile manufacturers}} before falling out of common usage. [https://www.bloomberg.com/news/articles/2019-03-27/warren-calls-for-breakup-of-big-ag-in-appeal-to-family-farmers Big Ag] is sometimes used to describe the farming and agricultural industry, and while the rest are purely fictional, Randall could be imagining a possible future in which these industries become big players in the political arena. &amp;quot;Big Foot&amp;quot; is likely a reference to the mythical creature {{w|Bigfoot}}.&lt;br /&gt;
&lt;br /&gt;
[https://bulbapedia.bulbagarden.net/wiki/Chansey_(Pok%C3%A9mon) Chansey], mentioned in the title text, is a {{w|Pokémon}} who carries around an egg in her marsupial-like front pouch. Randall has seemingly ruminated on the phrase &amp;quot;in the pocket of Big Egg&amp;quot; while drawing the comic, and began to think of Chansey, for whom the phrase would be rather literal.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&amp;lt;!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.--&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The word league is in a diamond-shaped region, which probably connotes to the baseball diamond.&lt;br /&gt;
&lt;br /&gt;
I think Randall kind of missed an opportunity with the title text: he should have used the new terms as a way to fill the blank areas in the diagram, for instance 'Great Emerald' for the currently empty set Great+Small+Little+Large.[[Special:Contributions/141.101.99.221|141.101.99.221]] 14:31, 11 March 2019 (UTC)&lt;br /&gt;
:No, I think the diagram itself is meant to be completely correct. But I didn't check all 100+ combinations. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 14:57, 11 March 2019 (UTC)&lt;br /&gt;
::Yes, I believe the diagram is correct now, but as per the title text Randall will start using new combinations of terms, probably to get their usage mainstream and move the location of the words in the diagram. I'm saying he should have created terms that would fill some blank areas. For instance, his Large Dipper would make Dipper appear in the Big+Little+Large area where we already have League.[[Special:Contributions/141.101.99.95|141.101.99.95]] 15:16, 11 March 2019 (UTC)&lt;br /&gt;
:::I understood what you said (the first time around) and agree.  Randall's title text is to acknowledge or engage the patterns he's discovered in the comic (as usual), and he could do that more thoroughly by making up words that would make the chart more balanced.  [[Special:Contributions/162.158.78.100|162.158.78.100]] 16:27, 11 March 2019 (UTC)&lt;br /&gt;
:He could also have placed “man” between “little” and “big” just to reference the movie ☺&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Any such diagram will inevitably have small lacunae. But &amp;quot;Friendly Giant&amp;quot; is a particularly large one. [[Special:Contributions/162.158.63.172|162.158.63.172]] 15:21, 11 March 2019 (UTC)&lt;br /&gt;

Endian? Scott? Tits?[[Special:Contributions/108.162.219.112|108.162.219.112]] 15:23, 11 March 2019 (UTC)&lt;br /&gt;
:Yeah, what about Little Endian? It's missing! [[Special:Contributions/172.68.143.156|172.68.143.156]] 19:28, 11 March 2019 (UT&lt;br /&gt;

Besides the transcript of what's in each category, what about a table to explain ''why'' the items categorized as they are, like:&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
!Item&lt;br /&gt;
!Big&lt;br /&gt;
!Great&lt;br /&gt;

|butterfly&lt;br /&gt;

{Unsigned|172.69.62.160}&lt;br /&gt;
:Yeah, it seems reasonable, I like it. Add it [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 15:57, 11 March 2019 (UTC)&lt;br /&gt;
::Second but leave the unused cells blank dont put N/A in the cell. [[User:M|M]] ([[User talk:M|talk]]) 16:15, 11 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I don't know why, but the shape of this diagram feels really satisfying to me. [[User:Hawthorn|Hawthorn]] ([[User talk:Hawthorn|talk]]) 16:29, 11 March 2019 (UTC)&lt;br /&gt;
:For me it’s just hard to look at. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 16:41, 11 March 2019 (UTC)&lt;br /&gt;
:Came here to say exactly that.  The symmetry is really pleasing.  I've been considering how effective adding colours would be as well. [[User:Cosmogoblin|Cosmogoblin]] ([[User talk:Cosmogoblin|talk]]) 17:55, 11 March 2019 (UTC)&lt;br /&gt;
::It looks like these style Venn diagrams are generated by http://bioinformatics.psb.ugent.be/webtools/Venn/ ... haven't tried it myself.  Don't know if they invented it or took it from elsewhere. [[Special:Contributions/162.158.79.149|162.158.79.149]] 21:17, 11 March 2019 (UTC)&lt;br /&gt;
:Could it be because they look like eggplants?  Kind of like the eggplant emojis? [[User:N0lqu|-boB]] ([[User talk:N0lqu|talk]]) 15:45, 12 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Again I wonder if he does these sorts of comics just to see how far we'll take it [[User:Cgrimes85|Cgrimes85]] ([[User talk:Cgrimes85|talk]]) 16:51, 11 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Uhhh...isn’t the bottom part just the transcript?[[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 17:08, 11 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Shouldn't this go in the Venn Diagram category? [[Special:Contributions/172.68.132.95|172.68.132.95]] 00:10, 12 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Can anyone make the table's cells be more regular in size across columns? [[Special:Contributions/172.68.132.95|172.68.132.95]] 00:54, 12 March 2019 (UTC)&lt;br /&gt;
:Done [[Special:Contributions/141.101.104.35|141.101.104.35]] 15:28, 12 March 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I am disappointed that he only referenced the &amp;quot;little big planet&amp;quot; game but not the &amp;quot;little big adventure&amp;quot; one. [[Special:Contributions/141.101.96.187|141.101.96.187]] 08:04, 12 March 2019 (UTC)&lt;br /&gt;

		<summary type="html">&lt;p&gt;172.68.142.179: fixed typo &amp;quot;comands&amp;quot; to commands&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;On {{w|April_Fools%27_Day|April Fools' Day}} in 2010 [[Randall]] altered the website to mimic a {{w|Unix}} command line interface. This interface is still available on [https://uni.xkcd.com uni.xkcd.com] and the source code is available on [https://github.com/chromakode/xkcdfools GitHub].&lt;br /&gt;
&lt;br /&gt;
The comic [[721: Flatland]] which was released on March 31, 2010 was still up on April 1st, 2010, but had in it self nothing to do with the Unix interface or the April Fools' Day joke of that interface.&lt;br /&gt;
&lt;br /&gt;
This Unix interface is thus in itself not one of Randall's [[:Category:April fools' comics|April fools' comics]], but since also the not existing comic [[404: Not Found]] is listed in that category, this stunt is none the less listed under these comics.&lt;br /&gt;
&lt;br /&gt;
'''The terminal lists a few available commands:'''&lt;br /&gt;
* &amp;lt;code&amp;gt;next&amp;lt;/code&amp;gt; shows the next comic. Shows the error &amp;quot;Time travel mode not enabled&amp;quot; on the last comic (see &amp;lt;code&amp;gt;enable time travel&amp;lt;/code&amp;gt;).&lt;br /&gt;
* &amp;lt;code&amp;gt;prev&amp;lt;/code&amp;gt; shows the previous comic.&lt;br /&gt;
* &amp;lt;code&amp;gt;first&amp;lt;/code&amp;gt; shows the first comic.&lt;br /&gt;
* &amp;lt;code&amp;gt;last&amp;lt;/code&amp;gt; shows the last comic.&lt;br /&gt;
* &amp;lt;code&amp;gt;display [number]&amp;lt;/code&amp;gt; shows the comic with the specified number.&lt;br /&gt;
* &amp;lt;code&amp;gt;random&amp;lt;/code&amp;gt; shows a random comic.&lt;br /&gt;
* &amp;lt;code&amp;gt;ls&amp;lt;/code&amp;gt; shows the content of the current directory.&lt;br /&gt;
* &amp;lt;code&amp;gt;cat [filename]&amp;lt;/code&amp;gt; shows the content of the file.&lt;br /&gt;
* &amp;lt;code&amp;gt;cd [directory]&amp;lt;/code&amp;gt; changes to the specified directory.&lt;br /&gt;
&lt;br /&gt;
'''But there are several undocumented commands as well:'''&lt;br /&gt;
* &amp;lt;code&amp;gt;a/s/l&amp;lt;/code&amp;gt; [https://www.urbandictionary.com/define.php?term=a%2Fs%2Fl A/S/L] is not a unix command, but an acronym of Age/Sex/Location. The following replies are possible:&lt;br /&gt;

: &amp;lt;code&amp;gt;42/M/FBI Field Office&amp;lt;/code&amp;gt; answered by an FBI agent (referencing the old [http://tvtropes.org/pmwiki/pmwiki.php/Main/ThereAreNoGirlsOnTheInternet trope] that all girls on the internet are FBI agents impersonating them).&lt;br /&gt;

&lt;div&gt;I have deleted the entire paragraph with the Alternatively, explanation that this could be an analogue to the process of meiosis and pregnancy... It seems extremely far fetched to me... [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:01, 27 April 2016 (UTC)&lt;br /&gt;

Seconded. This is a bizarre comic, and there will be a bizarre explanation, but that is clearly not it. [[Special:Contributions/141.101.70.181|141.101.70.181]] 13:04, 27 April 2016 (UTC)&lt;br /&gt;

I third the above comments. It could also help explain the title text, as the 1955 panel shows a broken and failed cycle, which can happen when a detrimental mutation (like weak wheel linkages) is selected by the AI to be passed on. {{unsigned ip|173.245.54.52}}&lt;br /&gt;
&lt;br /&gt;
Would have seconded it, only looks like I'm fourthing it, instead. Also I adjusted 1925's transcript description as the numbers were wrong.  (I also suspect it's related to the stabilisation applied to the [https://postalheritage.wordpress.com/tag/pentacycle/ Pentacycle], only without visible in/out-of-page stability. (Because the third dimension doesn't exist? Well apart from 1900 that looks to be a bicycle version of the [http://www.thisvictorianlife.com/cycling.html Rudge], with a solid insert to the spoked wheel ('poor man's disc-wheel' kit?) obscuring all but the spurious over-wheel drive-chain and the rider's head.)

&lt;br /&gt;
Can you include the 'Alternatively,' explanation down here so I (and presumably others) don't have to wade through the page's history?  We could list all sorts of far-fetched explanations, it has definitely happened on other comics. {{unsigned ip|108.162.242.135}}&lt;br /&gt;
&lt;br /&gt;
I have a feeling that this is related to the idea that nobody can draw a bicycle. For example, [https://www.behance.net/gallery/35437979/Velocipedia this artist created 3D renderings of bicycles drawn by strangers]. [[User:Rael|Rael]] ([[User talk:Rael|talk]]) 14:51, 27 April 2016 (UTC)&lt;br /&gt;
:I'm not certain there's a relation, unless it's Randall pointing out that it's rather difficult for him to draw a bicycle while maintaining a simple stick-figure theme? Regarding that guy's experience asking strangers to draw a bicycle: Most people do not draw very well. At all... Many people can't even draw faces very well &amp;amp; we look at faces *all the time*. We're predisposed to spot faces even when they're not there, yet most people get the proportions wrong. I'm not sure why he was surprised that most people couldn't draw a mechanically accurate representation. Bicycles are moderately complex machines that many people feel overwhelmed by, to the point of omitting otherwise advantageous equipment, such as multiple gears. {{unsigned ip|141.101.98.25}}&lt;br /&gt;
::Well, as you could see, most of the people who tried to draw bicycles were able to at least sketch something that resembled a bicycle.  You don't have to be an artist to get the basic idea down.  The thing I found more interesting was that many of the drawings were just plain wrong (e.g. the chain going all the way between the front and back wheels) or lacked significant parts.  In some cases, it's clear that the drawer just overlooked one or two things - easy to do - and in other cases, it shows that the person actually had difficulty recalling the basic structure of a bicycle.  Everyone who participated clearly knows what a bike is and, from a practical standpoint, how it works.  But from a brain-sciences perspective, there's a difference between the symbolic memory of a bicycle (I know what it is and how to use it, and I can remember what color mine is, etc.) and detailed visual memory (I know all the parts and can reconstruct them visually).  That's what's being exposed in that experiment. :)&lt;br /&gt;
::That said, I agree that I don't think there's a strong relation between this comic and that experiment.  I think it's more likely that Randall is poking fun at both genetic algorithms (perhaps self-learning AIs) and design prototyping (throw a bunch of stuff at the wall and see what sticks).

Does anyone else think the 1980 bike resembles a horse-drawn carriage minus the horses? Specifically, the two long parts Megan is holding look like reins. [[Special:Contributions/108.162.246.122|108.162.246.122]] 16:06, 27 April 2016 (UTC)&lt;br /&gt;

:: Indeed, there is a movement for both chopper and lowrider bicycles. I have seen both and the 1980's bicycle looks almost like a lowrider bike I saw in Arvada CO probably in 2014. [[Special:Contributions/162.158.255.89|162.158.255.89]] 17:29, 27 April 2016 (UTC)&lt;br /&gt;
The 1980 design is reminiscent of long-wheelbase recumbent bicycles, which were originally designed in the 1930s and enjoyed a resurgence starting in the later 20th century.  An Iowa company produced a bicycle called a 'Linear' about this time which did have extremely long handlebars; steering it was more like using a tiller on a boat.  The fallacy here is using a chaindrive to power the (steerable) front wheel; this simply would not work. [[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 20:18, 28 April 2016 (UTC)&lt;br /&gt;
:actually, chain drive to the front wheel would work fine.  You would have to fix the front wheel rigidly to the frame, of course, which means the rear wheel must do the steering.  It seems possible the odd structure holding the rider (Megan) is intended to let her steer the rear wheel by twisting her body. {{unsigned ip|108.162.212.50}}&lt;br /&gt;
I came here thinking I did not get the joke. After reading the description I see I am not the only one. [[Special:Contributions/108.162.246.119|108.162.246.119]] 16:23, 27 April 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Same here. I think the joke is just Randall exaggerating actual bicycle designs. Either that or it's &amp;quot;The Evolution of the Bicycle&amp;quot; in an alternate reality. [[Special:Contributions/173.245.52.62|173.245.52.62]] 17:30, 27 April 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is the point of the timeseries that while most things in biology evolve gradually over time (think all of those Evolution of Man t-shirts), undergoing great changes in form, we basically hit all the possible bicycle designs in the first 20 years and it has gone along essentially unchanged ever since? There are specialty bikes made possible by new frame materials, but they are all &amp;quot;Safety Bicycles&amp;quot;. The takeaway of the comic could be either about the simplicity of the solution to the bicycle &amp;quot;problem&amp;quot;, or about the difference between engineered design and the natural selection.

&lt;br /&gt;
The 1955 design reminds me of the movie &amp;quot;Rubber&amp;quot;. http://www.imdb.com/title/tt1612774/ Is that too tenuous of a connection?&lt;br /&gt;
[[User:ChrisPwildcat|ChrisPwildcat]] ([[User talk:ChrisPwildcat|talk]]) 19:11, 27 April 2016 (UTC)&lt;br /&gt;
: I definitely made the same connection. (Wow, the scene where the tire stares into its own reflection &amp;amp; remembers all of its actions so far... I felt empathy for that tire. WTH?) The 1955 design definitely implies that the wheels are trying to kill Cueball. {{unsigned ip|141.101.98.25}}&lt;br /&gt;
:: Perhaps you are feeling sorry for the 1955 tires.  That is because you are crazy.  The 1980 design is much better. &amp;amp;lt;/ikea&amp;amp;gt; :) [[User:KieferSkunk|KieferSkunk]] ([[User talk:KieferSkunk|talk]]) 14:38, 29 April 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
This reminds me of certain videos I watched about evolution, in sequence, the picutres could be describe various models (some of them apparently unfit, thus discontinued) of bicycles as if they were derived from the laws that govern evolution (random mutation and natural selection).

&lt;br /&gt;
(Re: 1955) &amp;quot;This is obviously the most ridiculous of all of these designs&amp;quot; - clearly, someone has really badly misspelt the word &amp;quot;awesome&amp;quot; here. Please fix. [[Special:Contributions/141.101.98.92|141.101.98.92]] 08:12, 28 April 2016 (UTC)&lt;br /&gt;

&lt;br /&gt;
Could this be related to either UI design philosophies or business process design ideas that prevailed in those eras? [[Special:Contributions/162.158.255.18|162.158.255.18]] 20:00, 19 May 2016 (UTC)&lt;br /&gt;

&lt;br /&gt;
Quick question: I noticed this explanation is included in &amp;quot;Category:Multiple Cueballs&amp;quot;.  Is this correct?  It stands to reason that we may just have the same Cueball appearing in multiple photos as he attempts to demonstrate how to use each bike design.  If we do consider this an instance of multiple Cueballs, should we also have a category for multiple Megans, since she appears three times as well?

&lt;br /&gt;
In my honest opinion, it is a reference to https://www.youtube.com/watch?v=GOFws_hhZs8 [[Special:Contributions/162.158.196.191|162.158.196.191]] 00:09, 2 May 2016 (UTC)GianniPiccioni&lt;br /&gt;

Could the 1940 design resemble a tank? It was the beginning of WWII. {{unsigned ip|141.101.70.151}}&lt;br /&gt;
&lt;br /&gt;
Regarding the explanation of the 1900's design: &amp;quot;... but it's unclear what he's doing.&amp;quot;: Imho it's not unclear but quite obvious that Cueball's operating the device with somthing like this: http://thumbs.dreamstime.com/z/industrial-wheel-valve-handle-vintage-rusty-equipment-machine-part-40567595.jpg What do you think? [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 12:37, 2 May 2016 (UTC)&lt;br /&gt;
: And for the 1940's design: Why does using a pole not count for propulsion and steering? https://en.wikipedia.org/wiki/Punt_%28boat%29 [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 12:49, 2 May 2016 (UTC)&lt;br /&gt;
:: I'm honestly not sure how you can make out what Cueball is doing on the 1900 bike - do you have access to a higher-resolution image than I do?  Even zooming in on the one in the comic, I can only make out that Cueball is standing on the thing, but otherwise not determine what he's doing.  As for the 1940 design: Pushing the pole against the ground is a means of external propulsion - as in, the bike has no way to be propelled within itself (pedals, etc.).  Using the pole on the ground is in the same vein as pushing a wheelbarrow from behind - the only difference is that the person pushing the pole is on the bike, and so you can still call it a vehicle. [[User:KieferSkunk|KieferSkunk]] ([[User talk:KieferSkunk|talk]]) 19:51, 3 May 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
:: Maybe my mind is just filling the gaps, but I derive it from Cueball's posture. But indeed, I cannot actually see what he's doing. Maybe we could agree on something like &amp;quot;Due to low resolution it's not perfectly clear what he's doing, but presumably the upper wheel might be something like a big crank wheel Cueball's operating&amp;quot;? For the 1940's: To be honest I don't see why this should be called &amp;quot;external&amp;quot; (and therefore being invalid as propulsion at all?). The wheelbarrow on the other hand is external. Why? The 1940's design is - from a propulsion point of view - the same as a rowboat, while the wheelbarrow is a sailboat. Or if you get more modern: The 1940's design is a normal rocket while the wheelbarrow is this: https://en.wikipedia.org/wiki/Beam-powered_propulsion. But that's not my point. I simply want to know what's making using a pole invalid in regard to being a means of propulsion at all.

&lt;br /&gt;
Someone keeps insisting that Megan appears 4 times and Cueball only 3, and at one point they specifically said it was Megan on the 1900 bike.  I'm pretty sure it's Cueball on the 1900 bike, so he would appear in 1825, 1900, 1915 and 1955, with Megan showing up in 1860, 1940 and 1980.  Does anyone see differently here? [[User:KieferSkunk|KieferSkunk]] ([[User talk:KieferSkunk|talk]]) 20:09, 3 May 2016 (UTC)&lt;br /&gt;
: Agree. 3 Megan, 4 Cueball (and 1 Ponytail) [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 07:17, 4 May 2016 (UTC)&lt;br /&gt;
&lt;br /&gt;
On the 1925 bicycle, I don't think it's just the wheels at the ends that touch the ground; it seems like all of them do. A reason for the wheels at the end to be farther down could just be because of the way Randall accidentally drew them; when I draw fractals like that, it's hard to keep the tiniest bits in line with the rest because of how small they would have to be (don't know if that makes sense at all).

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 2098&lt;br /&gt;
| date      = January 14, 2019&lt;br /&gt;
| title     = Magnetic Pole&lt;br /&gt;
| image     = magnetic_pole.png&lt;br /&gt;
| titletext = People keep trying to come up with reasons that we should worry about the magnetic field collapsing or reversing, but honestly I think it's fine. Whatever minor problems it causes will be made up for by the mid-latitude auroras.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a CONVECTION CURRENT IN THE OUTER CORE and a thing happening. Well, four things. Well, four things and a lizard. Include relevant wikipedia and news article links. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Over the last couple of months, {{w|Earth's magnetic field|Earth's magnetic fields}} have been [https://www.nature.com/articles/d41586-019-00007-1 shifting rapidly]. Although the magnetic fields do move regularly, the current shift has been unexpected and unprecedented. As many location systems are reliant on the magnetic fields to function, the accuracy of such tools is being shifted beyond the maximum acceptable error.&lt;br /&gt;
&lt;br /&gt;
Locational and navigational systems use the magnetic field, in addition to a model, to do fancy math and pop out data. Due to the rapid shifts, a new model was scheduled to be out; however, because of the {{w|United States federal government shutdown of 2018–2019|US government shutdown}}, the model has been considerably delayed.&lt;br /&gt;
&lt;br /&gt;
As shifts occur, the error of geopositional data will increase until a new {{w|World Magnetic Model|model}} is released. The effect is especially pronounced as you move toward the poles. &lt;br /&gt;
&lt;br /&gt;
Cueball is saying that because of the currently published {{w|magnetic declination}} data being slightly incorrect, his {{w|Schooner|schooners}} (old merchant sailing ships) may go off-course and crash on {{w|Shoal|shoals}}. This is to illustrate how magnetic pole shift doesn't actually have much of an effect on too many people's daily lives, since most people don't need to worry about things like ship navigation and modern ships use navigation aids that do not rely on magnetic poles location &amp;amp;ndash; in contrast to old vessels which used a {{w|compass}} mostly.&lt;br /&gt;
&lt;br /&gt;
Since the movement is only equal to about two-fifths of a degree, it wouldn't cause very much disruption for [[Cueball]] or require him to adjust anything about his lifestyle or habits, but since the speed of the change has been steadily increasing over the past few years, it may mean we are heading for a geomagnetic reversal in the next few decades; something very exciting indeed. During a magnetic reversal, the poles wouldn't just switch places, but several different poles would form and interact very chaotically, and, statistically speaking, it's likely that one of them would end up close enough to where [[Randall]] lives to cause auroras to become more common at some point during the transition.&lt;br /&gt;
&lt;br /&gt;
In the title text, Randall mentions that there are reasons people could be concerned, but says that they would be more than made up for by newly being able to experience mid latitude auroras.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[White Hat and Cueball are talking to each other. White Hat has a cellphone in his hand, while Cueball is raising his hands in the air in mock exasperation.]&lt;br /&gt;
:White Hat: I just read that the Earth's North magnetic pole is drifting rapidly.&lt;br /&gt;
:Cueball: Oh no! I must update our declination tables post haste, lest our merchant schooners run aground on the shoals!&lt;br /&gt;
&lt;br /&gt;
:[Caption below the panel:]&lt;br /&gt;
:I like when the Earth's magnetic field does weird stuff, because it's a huge, cool, urgent-seeming science thing, but there's nothing I personally need to do about it.&lt;br /&gt;

| titletext = The phone will be collected by the toll operators and mailed back to you within 4-6 weeks.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This is the fifth entry in the ongoing [[:Category:xkcd Phones|xkcd Phone series]], and once again, the comic plays with many standard tech buzzwords, and horribly misuses all of them, to create a phone that sounds impressive but self-evidently isn't to even the most ignorant customer. The previous comic in the series [[1707: xkcd Phone 4]] was released almost 8 months before this one and the next [[1889: xkcd Phone 6]] was released 7 months later.&lt;br /&gt;
&lt;br /&gt;
The slogan beneath the phone, &amp;quot;We're trying to catch up to Apple but refuse to skip numbers&amp;quot;, is a reference to inconsistent product numbering, such as {{w|Samsung}} releasing the {{w|Note 7}} after the {{w|Note 5}}, likely in an attempt to catch up to the numbering of either the {{w|iPhone}} or {{w|Galaxy S}} series, both of which were already at 7. Similarly, there was also no official ''iPhone 2''. But there is an [[xkcd Phone 2]] available. The trademark sign behind the word &amp;quot;numbers&amp;quot; possibly indicates a reference to the {{w|Numbers (spreadsheet)|Apple spreadsheet app}} with the same name.&lt;br /&gt;
&lt;br /&gt;
This phone seems to have a curved display. But the edges are curved down and not up, as they are on other curved phones.&lt;br /&gt;
&lt;br /&gt;
The title text that says that the phone will be returned to you by the toll operators is a reference to E-ZPass partnership feature; see explanation in the table regarding that feature.&lt;br /&gt;
&lt;br /&gt;
===List of features===&lt;br /&gt;
&lt;br /&gt;
; Hook shot&lt;br /&gt;
&lt;br /&gt;
: In ''{{w|The Legend of Zelda}}'' the [http://zelda.gamepedia.com/Hookshot Hookshot] is a recurring weapon/tool.  It is a machine consisting of a chain and hook. When used, the chain extends and sends the hook which is attached to it. It is used to bring items to {{w|Link (The Legend of Zelda)|Link}} or bring Link closer to a goal (''Link'' is the name shared by the main protagonists, each possessing the Spirit of the Hero). Likely a reference to new video game ''{{w|The Legend of Zelda: Breath of the Wild}}'', which was released a week prior to this comic (ironically, that game does not feature the Hookshot).&lt;br /&gt;
&lt;br /&gt;
In the comic the hook shot is shown as a small port upon the phone's top; the hook itself is not visible, suggesting it is contained in the device until use. Most Hookshots in the game series are large enough to be grasped in or encompass the hand, with the hook being large and extending out of the tool even without use. The size of the port and absence of the hook before use implies a very small hook and a very thin chain, making it impractical for use in either of the tool's functions.&lt;br /&gt;
&lt;br /&gt;
; Bluetooth speaker&lt;br /&gt;
&lt;br /&gt;
: {{w|Bluetooth}} speakers are often used to play audio from a smartphone wirelessly, usually with more volume and better quality than the phone's small built-in speaker can provide. Embedding a bluetooth speaker into the phone would allow the phone to play audio from outside sources through its built-in speaker, which could be useful if no better speakers were available but would generally be avoided given the previously noted limitations of phone speakers. This is perhaps a jab at the current trend of playing music or Internet content audibly in public through the tiny, tinny speaker embedded in most phones. The Bluetooth speaker is located in the normal place for a phone's speaker.&lt;br /&gt;
&lt;br /&gt;
; Stained-glass display&lt;br /&gt;
&lt;br /&gt;
: {{w|Stained glass}} is colored glass, traditionally used for decorative windows in buildings most often churches. It is generally much thicker and because of the color much less transparent, especially for some colors, than the glass types normally used for touch-screens, making the phone difficult to use as it would remove some of the colors shown on the screen below the glass. A typical feature noticed about the glass for real phones would be its strength, as in work phones for construction workers.&lt;br /&gt;
&lt;br /&gt;
; Gallium chassis remains solid up to 85&amp;amp;deg;F&lt;br /&gt;
&lt;br /&gt;
: Many high-end electronic devices have chassis made of alloys of light metals such as {{w|magnesium}} or {{w|titanium}} rather than {{w|steel}} or {{w|plastic}}. Besides being lightweight and of superior quality and durability than ordinary sheet steel or cheap plastic, these are often perceived as bragging points by the users, boasting about 'rare' metal chassis.&lt;br /&gt;
&lt;br /&gt;
: {{w|Gallium}}, however, is an uncommon metal with a very low melting point of 85&amp;amp;nbsp;°F (or 29.8&amp;amp;nbsp;°C), making it one of only four pure metals (along with {{w|Mercury (element)|mercury}}, {{w|rubidium}} and {{w|caesium}}) that can be liquid around room temperature. Because the melting point is lower than the average {{w|human body temperature}} of 98.6&amp;amp;nbsp;°F (37&amp;amp;nbsp;°C) a gallium smartphone chassis would melt in the user's bare hand, assuming it hadn't already done so due to heat produced by its internal components. Even if the electronics had good heat management, cooling in smartphones is normally accomplished by distributing heat to the case, not exhausting it. &lt;br /&gt;
&lt;br /&gt;
: A similar real advertisement regarding the chassis would be that it was {{w|waterproof}} down to some depth (say, 85 feet or 25 meters). See also the feature below regarding this.&lt;br /&gt;
&lt;br /&gt;
; Soundproof&lt;br /&gt;
&lt;br /&gt;
: A {{w|Soundproof}} chassis could result in the unwanted effect that the speakers and microphone may not work as no sound may enter or leave the phones chassis. A more likely feature would be waterproof (see above point).&lt;br /&gt;
&lt;br /&gt;
; Can feel pain&lt;br /&gt;
&lt;br /&gt;
: Possibly a reference to {{w|intelligent personal assistant|intelligent personal assistants}} like {{w|Siri}}, {{w|Cortana (software)|Cortana}} or {{w|Amazon Alexa|Alexa}} gaining consciousness (see [[1807: Listening]] for the latter). Such {{w|artificial intelligence}} references is a [[:Category:Artificial Intelligence|recurring subject]] on xkcd. &lt;br /&gt;
&lt;br /&gt;
: This could mean that either the phone feels pain for damages inflicted upon it or it feels the user's pain level (regarding either physical and/or emotional pain).  The meaning would quickly become apparent for the user if the chassis melts on contact with exposed skin leaving the phone with &amp;quot;open wounds&amp;quot;. &lt;br /&gt;
&lt;br /&gt;
: This could be seen as a similar feature of the first xkcd phone, [[1363: xkcd Phone]], where the title text notices (among many other things) that the ''phone will drown'' if submerged in water. A similar thing is also mentioned for [[1549: XKCD Phone 3]]. That phone is ''waterproof but can drown''. Since this phone is soundproof but not waterproof, per the two points above, the drowning issue may still be relevant. The second phone, [[1465: xkcd Phone 2]], ''cries when lost'' a similar display of emotions/feelings. That phone also mentions waterproofing, but here it is only the interior, and although it is washable, it is only a one-time feature (like the fold-ability of this one; see two points below). Finally it also [[1707: xkcd Phone 4]] mentions that it is waterproof, but not between 30-50 m down...&lt;br /&gt;
&lt;br /&gt;
; E-ZPass partnership: Phone can be dropped into coin basket to pay tolls&lt;br /&gt;
&lt;br /&gt;
: {{w|E-ZPass}} is an electronic toll collection system. The vehicle drives through the toll lane without stopping, and sensors detect the pass and deduct the appropriate amount from the user's account. The phone's integration with E-ZPass is absurd since the phone needs to be dropped into a coin basket to work. Not only would you have to stop in order to throw the phone into the coin basket, which defies the idea of E-ZPass, but you would also lose your phone.&lt;br /&gt;
&lt;br /&gt;
: In the '''title text''', however, it says that the phone will be retrieved by the toll operators and returned by mail within 4–6 weeks. So this slightly mitigates the problem of losing the phone, but there would be about a month where the phone could not be used.&lt;br /&gt;
&lt;br /&gt;
; Foldable (once)&lt;br /&gt;
&lt;br /&gt;
: Almost anything long and slim can be &amp;quot;folded&amp;quot; by simply snapping it in half. But as it says, this can only be done once, because the phone cannot be unsnapped and will not work any more once it has been folded. &lt;br /&gt;
&lt;br /&gt;
: This is a reference to the [http://www.digitaltrends.com/mobile/samsung-foldable-smartphone-news/ rumors of the new Samsung Galaxy X] that is really foldable like a piece of rubber. See [https://www.youtube.com/watch?v=fro_CNjxYwM this video].&lt;br /&gt;
&lt;br /&gt;
: It could also refer to the fact that a version of iPhone had a weak spot that lead it to easily folding and breaking. And it could be a reference to {{w|Flip (form)|flip phones}}.&lt;br /&gt;
&lt;br /&gt;
; Screen transfers images to skin&lt;br /&gt;
&lt;br /&gt;
: Transferring images to the skin sounds like either real {{w|tattoos}} or the water tattoos used by children or other kinds of {{w|temporary tattoos}}. Likely it should be understood that it would be possible to transfer the image displayed on the screen to your skin, hopefully when activating the feature rather than by accident, and, preferably, also not permanently. This may also be a reference to the experimental Cicret Bracelet's ability to project images onto your arm: [http://www.snopes.com/photos/technology/cicret.asp]&lt;br /&gt;
&lt;br /&gt;
; Retina storage&lt;br /&gt;
&lt;br /&gt;
: This is a play on the name of Apple's prized &amp;quot;{{w|Retina Display}}&amp;quot;. The joke may be in reference to Apple's possession of a trademark for the word &amp;quot;retina&amp;quot; in regards to computer equipment, which is made to seem absurd by the unusual use. It is not made clear whose retinas are meant to be stored. It could also be a reference to retinally implanted computers. The retina storage is a slot at the bottom of the phone right of the charging port.&lt;br /&gt;
&lt;br /&gt;
; Background task automatically catches and eats Pokémon&lt;br /&gt;
&lt;br /&gt;
: A reference to {{w|Pokémon Go}}, an augmented reality game where the goal is to go to specific locations and play a mini-game in order to catch virtual creatures called {{w|Pokémon}} (see [[1705: Pokémon Go]]). This phone apparently catches Pokémon automatically, similar to the external device {{w|Pokémon_Go#Pok.C3.A9mon_Go_Plus|Pokémon Go Plus}}. However, this feature also eats them, which is something that is not part of the game and wouldn't be desirable, as it is about collection and storing as many different Pokémon as possible. It could be a coincidence, but it seems funny that the label for this background feature is the only one that points at the back of the phone. &lt;br /&gt;
&lt;br /&gt;
; Supercuts partnership: Trims hair fed into charging port&lt;br /&gt;
&lt;br /&gt;
: {{w|Supercuts}} is an American hair salon chain that provides hair cuts and styling.  The implication here is that the user can get a haircut by Supercuts by sticking hair into the charging slot. This is not only impractical and would only work for hair long enough to be fed into the port, but it would most likely result in a bad haircut. Also the slot would soon be filled with hair. The charging slot is otherwise placed in the normal spot and looks like a regular charging port.&lt;br /&gt;
&lt;br /&gt;
: This feature could actually be quite dangerous if the hair is not removed from the charging slot afterwards because the hair could melt or catch fire inside the phone. &lt;br /&gt;
&lt;br /&gt;
; Squelch knob&lt;br /&gt;
&lt;br /&gt;
: {{w|Squelch}} is a feature of radios (CB, ham, scanner, etc) which quiets background noise when no usable signal is present.  It cuts off audio completely when only noise is present.  As different environments can have differing levels of background noise, an adjusment such as a knob is required to set the level at which the squelch circuit deactivates and lets audio through (&amp;quot;opening&amp;quot; or &amp;quot;breaking&amp;quot; the squelch). For a smartphone, perhaps this knob could control the &amp;quot;signal-to-noise&amp;quot; ratio of your Facebook feed or other social media platforms. It takes the place of the headphone jack, replacing the normal hole with a small knob.&lt;br /&gt;
&lt;br /&gt;
; IBM buckling-spring Home button&lt;br /&gt;
&lt;br /&gt;
: {{w|IBM}} {{w|Buckling spring|buckling-spring}} keyboards are favorites of geeks for the feeling of quality and auditory feedback (keys click loudly when pressed) they provide. Real smartphones' home buttons, typically located exactly as in this image, provide little to no such satisfaction when pressed.&lt;br /&gt;
&lt;br /&gt;
; Cot-caught merger switch&lt;br /&gt;
&lt;br /&gt;
: This is a reference to the {{w|cot–caught merger}}, a linguistic change happening among English speakers, particularly in some parts of North America and the British Isles, which causes caught (previously pronounced &amp;quot;kawt&amp;quot;) to be pronounced the same as cot (pronounced &amp;quot;kot&amp;quot;). The switch is clearly visible on the side of the phone. A real feature physically similar to this is the slide switch on the iPhone and iPad, allowing the user to (un)lock the orientation of the screen or to (un)mute the device.&lt;br /&gt;
&lt;br /&gt;
; 60x optical zoom camera&lt;br /&gt;
&lt;br /&gt;
: A powerful optical {{w|zoom lens}} is usually a desirable feature for cameras. However, as shown in the comic, it results in very bulky lens. If 60× zoom should be achieved the lens needs to be as big as shown on the backside of the phone, and the whole idea of being able to carry the smartphone easily in a pocket would be defied.&lt;br /&gt;
&lt;br /&gt;
: For that reason, such lenses are never used in smartphones, although rarely some devices, like the {{w|Samsung Galaxy Camera}}, use a smaller lens with a similar design. But this is no longer a smartphone. &lt;br /&gt;
&lt;br /&gt;
: This feature would seem to be a jab at the variety of add-on devices, including close-up lenses, handles, and external flashes, that are currently in use to enhance the phone's ability to function like a camera (and the {{w|selfie stick}}). &lt;br /&gt;
&lt;br /&gt;
: Some phones might instead mention their {{w|digital zoom}} level instead. But that is not a popular feature among photo enthusiasts, as digital zooming gains no additional optical resolution. Users would actually be better off using the maximum optical zoom, and then enlarging their images with photo-editing software, which might offer better, but slower, algorithms (e.g. {{w|linear resampling}} versus {{w|Lanczos resampling}}). Likewise, (mobile phone) cameras are often advertised with their high number of {{w|megapixel}}s, while retaining their small {{w|image sensor size}}. As each individual sensor gets less light, it creates more {{w|image noise}}.&lt;br /&gt;
&lt;br /&gt;
: Randall has made several comics about cameras before; see for instance [[1719: Superzoom]] and other comics linked via this.&lt;br /&gt;
&lt;br /&gt;
: Contrast the [https://www.easy-macro.com EasyMacro] band - 4x zoom with little appreciable thickness.&lt;br /&gt;
&lt;br /&gt;
: Assuming 60x is referring to the base focal length of the iPhone and that the xkcd Phone 5 has the same dimensions as the iPhone 7 Plus then in 35mm format this lens would be 30-1800mm f/0.4-f/24. This is a completely infeasible (but not physically impossible) lens in 35mm format, but similar small format lenses (albeit with more reasonable aperture ranges) do exist in mass production, for example the Nikon P900.&lt;br /&gt;
&lt;br /&gt;
; LORAN navigation&lt;br /&gt;
&lt;br /&gt;
: {{w|LORAN}} (Long Range Navigation) was a precursor to modern {{W|Global Positioning System|GPS}} navigation, using land-based transmitters. Once developed for sea shipping, it is accurate to about 300 meters (1,000 feet). The joke, of course, is that all modern smartphones have integrated GPS navigation which is far more accurate. Due to the much lower frequencies involved, reception of LORAN signals though is much better in areas with obstructed view of the sky. However {{w|LORAN#Commercial_use.2C_decommissioning|LORAN has been decommissioned}} more or less completely since before 2000.&lt;br /&gt;
&lt;br /&gt;
: Incidentally, some receivers of the {{w|Decca Navigator System}} (which operates on a similar principle as LORAN) featured moving map displays, something we associate with modern GPS devices. &lt;br /&gt;
&lt;br /&gt;
; 28-factor authentication&lt;br /&gt;
&lt;br /&gt;
: An {{w|Authentication#Factors and identity|authentication factor}} is a way of proving one's identity. There are [http://www.nikacp.com/images/10.1.1.200.3888.pdf 3 generally recognized forms]: something you know, something you have, and something you are. It can be a password, a fingerprint, a physical key, etc.... Secure applications may include two or more factors; a common example is the &amp;quot;PIN and chip&amp;quot; system used with credit cards, where you need both the card and secret code to authorize a transaction. Many online services now provide two-factor authentication to protect against password-based attacks. 28-factor authentication would likely be very secure in theory but also so impractical that it would be unusable. The user will need to prove their identity 28 different ways which would be so time consuming that would outweigh the convenience of a smart phone. A 2-factor smoke detector was soon after mentioned in one of the tips in [[1820: Security Advice]].&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[An image of a smartphone with a common optical camera lens attached on its back is shown. Over the entire length the case is slightly rounded. There are several features visible as bottom like features at the top and bottom of the front as well a microphone like slit at the top. A sliding switch is visible on the side, and at the bottom there is a knob, a connector port and a small slit. Clockwise starting from the top left all the labels read:]&lt;br /&gt;

}}&lt;br /&gt;
==Explanation==&lt;br /&gt;
The comic makes fun of Wikipedia talk pages. On Wikipedia, every article has a place to discuss the content of the page, called a &amp;quot;{{w|Help:Using talk pages|talk page}}&amp;quot;. In this case, the comic talks about the talk page of an article about a city. While some of the topics are quite normal for such a page (e.g. the quality of the images) others are not (e.g. too many murders and mine disasters in the city). The topics discussed suggest that the city has many problems and is a bad place to live in or visit.&lt;br /&gt;
&lt;br /&gt;
The topics show a common problem at Wikipedia's talk pages: People often use them as a place to talk about the ''subject'' of the article, but it is for talking about the ''article'' itself. Someone at the top of the talk page is suggesting a better name for the city.&lt;br /&gt;
&lt;br /&gt;
The article repeatedly refers to &amp;quot;the murders&amp;quot;, suggesting that the city might be well-known for them. It seems that the editors cannot agree on how notable &amp;quot;the murders&amp;quot; are. &amp;quot;Not that notable&amp;quot; refers to Wikipedia's general criteria for including information in articles. Material which is not noteworthy should be removed; however, different editors often disagree about what is notable, resulting in conflicting edits as text is inserted and then removed (an &amp;quot;edit war&amp;quot;). Someone replies that &amp;quot;all cities have murders&amp;quot;. While true, many cities in low-crime countries would not have a series of them so well-known that when someone talks about &amp;quot;the murders&amp;quot; any reader could be expected to know what they are talking about, making this sound like an attempt to make the city sound nicer than it is. &amp;quot;I think the murderer is reverting my edits&amp;quot; suggests the murders are being committed by ''one person'' who is influencing how they are shown on Wikipedia - perhaps trying to prevent Wikipedia from publishing evidence of them or possibly publicise them by adding ''more'' information about them. This raises the possibility that the discussion of the murder visible in the infobox picture may have been ''initiated by the murderer''.&lt;br /&gt;
&lt;br /&gt;
The {{w|WP:Infobox|infobox}} is a short fact sheet that many articles in the (English) Wikipedia have; it generally includes an image illustrating the subject of the article. The question of which picture is best for the infobox (because this image is so prominent) can cause edit wars. It emerges that the photograph of the city has a murder in it. Instead of forwarding the picture to law enforcement, someone uses the image editing software Photoshop to erase the murder so the picture will be less objectionable. It appears that murders are so common in the city that any random photograph of the city has a chance of showing a murder, to the point where a second photo proposed as a replacement for the infobox picture is found to show ''another'' murder.&lt;br /&gt;
&lt;br /&gt;
{{w|Voltaire}} was a French Enlightenment writer. As a prominent and very opinionated intellectual, [https://en.wikiquote.org/wiki/Voltaire#Misattributed he gets a lot of quotes falsely attributed to him]; most famously, he did not actually say &amp;quot;I disagree with what you say, but I will defend to the death your right to say it&amp;quot; (that was {{w|Evelyn Beatrice Hall}}).&lt;br /&gt;
&lt;br /&gt;
It seems that the people who are editing the article are getting desperate to find a non-bleak picture of the city. When a non-bleak picture is added, it turns out to be from the 2016 Disney film ''{{w|Zootopia}}''. The fictional city which is the setting and title of the film has a distinctive [http://vignette2.wikia.nocookie.net/disney/images/4/43/Zootopia_City_Full.jpg look] which is far from bleak, but is not a picture of the city. (Zootopia is called Zootropolis in many European countries for trademark reasons.)&lt;br /&gt;
&lt;br /&gt;
The city apparently is a mining city and there have been some mining disasters. An editor is complaining that this section is too long, but another editor points out that this is because there have been so many mining disasters that a large section is needed to cover the topic. &lt;br /&gt;
&lt;br /&gt;
{{w|1982 Secession}} refers to Key West, Florida seceding from the United States in 1982 to form the {{w|Conch Republic}}.&lt;br /&gt;
&lt;br /&gt;
A known problem on Wikipedia is &amp;quot;coatracking&amp;quot;, where people use articles to promote topics that are not strictly the subject of the article (perhaps by writing far more about them than is necessary, when they could just be mentioned in passing). Here, it emerges that the article on a city expresses a dubious opinion on condom use. This is against several Wikipedia policies: it would be irrelevant to the article and sounds like an editor's attempt to publicise their views.&lt;br /&gt;
&lt;br /&gt;
{{w|Andrew Lloyd Webber}} is an English composer famous for writing ''The {{w|Phantom Of The Opera}}''. Webber is also known for writing the music for ''{{w|Starlight Express}}'', a rock opera about anthropomorphized trains, which is probably another factor in the train station joke. Meanwhile, {{w|Frank Lloyd Wright}}, who shares his middle name and last initial, was an American architect, who designed more than 1,000 structures. As it turns out it was the composer who was responsible for the train station. Another editor announces he's putting a mention of a collapse of the station roof (presumably recently), the implication being Andrew is a lot better at composing than architectural engineering.&lt;br /&gt;
&lt;br /&gt;
It is complained that the article is promoting the &amp;quot;Lake Festival Laser Show&amp;quot; too much. In the title text, it emerges that the laser show is so impressive that it has caused a number of aeroplanes to crash. This probably refers to the fact that laser pointers should not be aimed at aircrafts, as they can be distracting to the pilots. The article has been promoting this area of crashed planes as the &amp;quot;Lakeshore Air Crash Museum&amp;quot;, despite it not having any educational purpose.&lt;br /&gt;
&lt;br /&gt;
==Examples==&lt;br /&gt;
*{{w|Talk:Key West, Florida#What's with the Chicken photo}} questions the relevance of free range chickens.&lt;br /&gt;
*{{w|Talk:Rio de Janeiro#Oh, there's no crime in Rio?}} suggests crime incidence in Rio has been suppressed to promote tourism.&lt;br /&gt;
*{{w|Talk:Kirkcaldy}} discusses naming.&lt;br /&gt;
*{{w|Talk:Isfahan}} has many naming proposals.&lt;br /&gt;
*{{w|Talk:Chattanooga, Tennessee}} has disputes over crime and notability of residents.&lt;br /&gt;
*{{w|Talk:Muara Bungo}} indicates someone ''repeatedly'' tried to delete the second-largest city in Jambi, Sumatra.&lt;br /&gt;
*{{w|Talk:Arvada, Colorado}} held a heated argument considerably longer than the article, concerning the existence of a scandal in the police department.  A year later, one editor deemed the issue unimportant and removed it entirely.&lt;br /&gt;
*{{w|Talk:Sutton-in-Ashfield}} discusses the cultural significance of town landmarks.&lt;br /&gt;
*{{w|Talk:Abergele}} has residents arguing over who should be included.&lt;br /&gt;
*{{w|Talk:Tucson, Arizona}}:&lt;br /&gt;
** ''I heard you can get Chicago-style deep dish pizza even in Tucson! Is this true? If so, it probably should be added to the article.''&lt;br /&gt;
** ''Um...I heard this place is kinda dangerous.''&lt;br /&gt;
** ''Shouldn't the headline-indicated shooting be included?''&lt;br /&gt;
** ''Why are there three photos showing snow in the vicinity of Tucson? I know snow is an event for us, but I think other Wikipedians know what it looks like.''&lt;br /&gt;

==Explanation==&lt;br /&gt;

Much like [[558: 1000 Times|comic 558]], this comic addresses the difficulty ordinary people have with large numbers. Though most if not all people intuitively understand the difference between one object and two objects, or one object and ten objects, or even one object and a hundred objects, as numbers increase most people's ability to innately conceive of the numbers being discussed decreases remarkably quickly. When numbers reach the millions and the billions, and especially the trillions, most people don't truly process the numbers at all, and instead conceive of them as some version of a drastically-oversimplified concept such as &amp;quot;very big.&amp;quot; Where comparing one to ten is simple, comparing &amp;quot;very big&amp;quot; to a different &amp;quot;very big&amp;quot; can prove extremely challenging, and will certainly require non-intuitive, conscious thinking.&lt;br /&gt;
&lt;br /&gt;
The comic represents this challenge by providing a graph which represents [[Randall]]'s ''intuitive'' conception of the values of various very large numbers, and said conception's misalignment with reality. Though some trends reflect the real value of the numbers on the graph, i.e. 100 million larger than 10 million larger than 1 million and 1 billion larger than 1 million, the curve is far from the linear (exponential on the log-scaled axes) path it should take, with 1 billion being intuitively understood as less than 100 million, based, presumably, on the fact, easily comprehended on an intuitive level, that '''100 is larger than 1''', and therefore the presence of 100 in 100 million places it at a higher value than the 1 in 1 billion would place the latter. In reality, of course, 1 billion is ten times larger than 100 million, but the comic deals not with actual reality, but with the perception of reality  of these numbers '''before conscious thought is applied'''. &lt;br /&gt;
&lt;br /&gt;
The most interesting parts of the graph, and the parts where the disconnect between intuition and reality becomes clearest, are the dashed sections labeled with question marks, the one between 100 million and 1 billion, the other between 100 billion and 1 trillion. Here two competing intuitive understandings compete for dominance. On the one hand, the intuitive understanding described above, with 100 trumping 1, would see the curve taking a sharp downturn. On the other hand, the path from 100 million to 1 billion is paved with such numbers as 500 million, 700 million, and 900 million, all of which would theoretically be seen intuitively as larger than 100 million, thanks to the fact that 9 is greater than 7, and 7 greater than 5, and so on, bending the curve up rather than down. These two conflicting intuitions leave Randall with no single intuitive path for the two dashed sections, leading to their dashed and questioned state.&lt;br /&gt;
&lt;br /&gt;
The comic's caption and title highlight another problem surrounding the intuitive grasping of large numbers: the flaws in the English words used for them. For instance, nothing about the world &amp;quot;million&amp;quot; suggests smallness relative to the world &amp;quot;billion&amp;quot; on an intuitive scale. This unintuitive language contributes greatly to the &amp;quot;100 trumps 1&amp;quot; intuitive fallacy described above. &lt;br /&gt;
&lt;br /&gt;
The title text references a classic, and highly relevant, example of a disconnect between British and American English. For all English speakers, 1 million constitutes 1,000 thousands, or, said less ambiguously, 10^6. However, the definition of billion varies depending which side of the Atlantic Ocean you happen to land on. In America, 1 billion equals 1,000 millions, or 1000*10^6=10^9. [https://en.oxforddictionaries.com/explore/how-many-is-a-billion/ In Britain], 1 billion equals ''1 million'' millions, or 10^6*10^6=10^'''12'''. In other words, 1 billion objects in England would register as 1,000 billion objects to an American, despite the fact that the number of objects has remained the same. Though people in Britain often use the American definition as of the past few decades, the fact that such a staggering difference of terminology was able to remain, and be almost completely unknown, perfectly highlights Randall's point about the failure of human intuition, and English terminology, in the discussion of extremely large numbers.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
A bra is pictured here, but instead of a traditional clasp, a {{w|Rubik's cube}} is used instead. The comic is a metaphor for how many men (and potentially women who don't wear bras) have difficulty removing their woman lover's bra before sex.&lt;br /&gt;
&lt;br /&gt;
Women who wear bras are going to be quite adept at unhooking their bras simply due to experience and muscle memory. However many common bra clasps are unique to bras and aren't found on other clothing, so their bra-less lover, lacking that experience, might fumble with the clasp for quite some time. In the heat of the moment, a lover may feel frustrated if they feel that the act of removing a bra is needlessly complicated and distracts from the activity at hand (namely sex). Depending on the clasp mechanism, attempting to remove the bra may seem as frustrating (hence the comic title) and complicated as solving a Rubik's cube.&lt;br /&gt;
&lt;br /&gt;
A literal bra clasped with a Rubik's cube would doubtless be especially frustrating, as someone wishing to remove the bra would have to solve the Rubik's cube every time in order to undo the clasp. This would doubtless prove annoying, especially for a partner who may want to remove the wearer's clothing without impediment.  A normal bra clasp can be tricky enough for the inexperienced user, but the addition of the Rubik's Cube element is going too far. However, it is possible that this is actually a nerdsnipe bra, as it appears to be a front-clasped bra, making the Rubik's cube a red herring.&lt;br /&gt;
&lt;br /&gt;
The title text is an imagined conversation between someone trying to undo this bra and someone who is likely wearing the bra. The first person explains that they can &amp;quot;do it&amp;quot; (i.e. undo the bra) in under a minute, which is a reasonably impressive skill to have if you are not a professional {{w|speedcuber}}. The second person replies that they've noticed, a sarcastic reply that relies on the alternative, sexual meaning of &amp;quot;do it&amp;quot;, implying a complaint about the first person's speedy performance in bed.&lt;br /&gt;

This comic shows the trend of having a simple and satisfactory explanation for something, and the exasperation with repeatedly realizing the inadequacy of the explanation, making revisions, and having a more complex yet still inadequate model.&lt;br /&gt;
&lt;br /&gt;
As Randall began his schooling, he learned that mixing the primary colours of pigment (red, blue, and yellow) together he could create almost any colour, so colour must be a combination of those 3 colours.&lt;br /&gt;
&lt;br /&gt;
He also learned about rainbows, and that the colours in the rainbow were just different wavelengths of light. Somehow these different wavelengths created unique colours. &lt;br /&gt;
&lt;br /&gt;
As Randall got older, philosophy and a discussion on perception came into play, and Randall came to the realization that his experiences are analogous to but not necessarily the same as his peers.&lt;br /&gt;
&lt;br /&gt;
As he got older, Randall learned about colour spaces as used in pigments, light, and printing, possibly from computer science (Red, Green, Blue; Red, Yellow, Blue; Cyan, Magenta, Yellow, Key) as well as the physics of electromagnetic rays and the biology of vision, understanding that visible light is a small portion of the electromagnetic spectrum - one crudely interpreted by the 3 types of cones in our eyeballs.&lt;br /&gt;
&lt;br /&gt;
Randall then learned about the opponent process model, wherein the signal from cones are not interpreted individually, but in difference to one another. &amp;quot;Responses to one color of an opponent channel are antagonistic to those to the other color. That is, opposite opponent colors are never perceived together – there is no &amp;quot;greenish red&amp;quot; or &amp;quot;yellowish blue&amp;quot;.&amp;quot; (from wikipedia)&lt;br /&gt;
&lt;br /&gt;
After that, Randall comes to understand the modeling of colour spaces and the design and limits of human visual perception - despite only having three cones, color space cannot be made into a triangle and still cover the gamut of human colour experience. &lt;br /&gt;
&lt;br /&gt;
Klein manifolds are beyond me, you'll have to fill in something about that.&lt;br /&gt;
&lt;br /&gt;
Eventually, the modeling becomes so complex (and yet still unsatisfactory) that Randall hopes it becomes someone else's problem.&lt;br /&gt;

I'm familiar with klein manifolds, they're peculiar 4D dimensional topological objects related to mobius strips. I have no Idea how they might relate to color, and doing a search for &amp;quot;a hyperdimensional four-sided quantum Klein manifold&amp;quot; returned pictures of bicycles... &lt;br /&gt;
&lt;br /&gt;
It might be good to point out in the explaination that he progresses from a dual nature of color (light, and paint) at the beginning and then trends to a unified explaination of color. [[Special:Contributions/172.68.142.179|172.68.142.179]] 18:27, 28 August 2017 (UTC) Sam&lt;/div&gt;</summary>

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|New page, what sandwich debate? What is &amp;quot;bacon&amp;quot; referring to?}}&lt;br /&gt;
&lt;br /&gt;
This comic is formatted as a graph showing various Internet trends over the years according to [https://trends.google.com/trends/explore?date=all&amp;amp;q=robot%20monkeys,pirates%20vs%20ninjas,zombies,bacon,definition%20of%20sandwich Google Trends]. The caption states that these &amp;quot;random obsessions,&amp;quot; as stated in the title, have 9-10 year cycles, and so predicts that the sandwich debate will be over by around 2024.&lt;br /&gt;
&lt;br /&gt;
Discussions about the definition of &amp;quot;sandwich&amp;quot; are surprisingly common on the web, such as &amp;quot;Is hot dog a sandwich?&amp;quot; (See this [https://www.reddit.com/r/Sandwiches/comments/6587ub/what_is_a_sandwich_debate/ discussion] on Reddit)&lt;br /&gt;
&lt;br /&gt;
The title text is a joke based on the debate over the definition of a sandwich. The speaker, presumably [[Randall]], starts out with the fairly reasonable stance that open-faced sandwiches are not true sandwiches, but then veers off into the absurd by claiming that literally every other physical object in the universe ''is'' a sandwich. We can only hope that Randall does not extend this view to {{w|Cannibalism|human beings}}.&lt;br /&gt;
&lt;br /&gt;
The other obsessions mentioned are, in order: robot monkeys, pirates vs ninjas, zombies, and bacon.&lt;br /&gt;
&lt;br /&gt;
Though the trend is dying out, as seen by the fact the graph is past the peak, there has been an explosion in bacon flavored/scented products as well as items of clothing and decor that look like bacon. The YouTube channel Epic Meal Time was also part of the bacon fad, as adding large quantities of bacon to the meal being prepared was one of the running gags of the channel.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Is it Blondie, just with more details to her hair?}}&lt;br /&gt;
A woman (maybe a different version of [[Blondie]], or Rachel from Animorphs) warns [[Cueball]] about not browsing for more than two hours in {{w|privacy mode|incognito mode}} as he might get stuck there forever.&lt;br /&gt;
&lt;br /&gt;
Incognito mode/private mode is a feature in a web browser that automatically clears any cookies and web history when the browser window is closed. One could become metaphorically &amp;quot;trapped&amp;quot; in this mode if they don't want to lose this data (for example if they've found a useful page which they want to refer back to, or if they're on a website like YouTube which uses cookies to provide recommended videos and they're finding the recommendations interesting), meaning that they can never close the browser again. Presumably this is more likely to happen after a longer browsing session. The only option to keep browsing data when the incognito/private session is closed is to bookmark or write down the URLs of interesting pages; there is no way to keep the cookies, so things such as recommended YouTube videos from within the incognito browsing session will inevitably be lost when it is closed.&lt;br /&gt;
&lt;br /&gt;
''{{w|Animorphs}}'' is a book series by {{w|K. A. Applegate}} featuring several teenagers who have a special power: they can {{w|shapeshifting|morph}} into various animals whose DNA they have absorbed through alien technology. However, if they stay morphed for over two hours, they will get stuck in that form until they die (this is presumably where the &amp;quot;two hours&amp;quot; in the comic comes from).&lt;br /&gt;
&lt;br /&gt;
In this comic [[Randall]] pokes fun at this by relating it to surfing in incognito mode/privacy mode in a browser. As explained above, staying for too long in incognito mode may cause the user to become &amp;quot;stuck&amp;quot; in this mode until something causes the browser to close, such as the browser/computer crashing or a power failure. This is analogous to the Animorphs who become stuck in animal form if they spend too long in that form.&lt;br /&gt;
&lt;br /&gt;
An alternative interpretation revolves around the use of incognito/private browsing modes when the user is paranoid. They may use this mode if, for example, they don't want the risk of anyone else discovering what they've been doing online, and they find it safer to simply use incognito mode rather than manually deleting the relevant cookies and browsing history afterwards. If they use this mode a lot, the sense of paranoia that initially led them to use incognito mode can reinforce itself, and over time they may become uncomfortable browsing outside of incognito mode. This is another way in which one may become &amp;quot;trapped&amp;quot; in incognito mode after extended use.&lt;br /&gt;
&lt;br /&gt;
===Relation to Animorphs===&lt;br /&gt;
&lt;br /&gt;
The caption explains that tech tips from Animorphs are the worst, i.e. the woman is an Animorph, and this was not good advice.&lt;br /&gt;
&lt;br /&gt;
The title text continues the idea that an Animorph tech support team would be the worst possible explaining that their solutions are always the same. And then it gives an example which references a common occurrence in the Animorphs book series wherein the protagonists uses their ability to morph into animals to infiltrate enemy strongholds. In the example it is an update for {{w|Apple Inc.|Apple's}} {{w|MacOS|OS X}} (a popular commercial operating system), that broke something. The solution is to infiltrate Apple by morphing apples. That advice, however, is nonsensical within the rules for morphing, put forth in the books, since the children can only turn into animals and not into fruits like apples.&lt;br /&gt;
&lt;br /&gt;
Animorphs has been referenced before, first only in the title texts of [[1187: Aspect Ratio]] and [[1360: Old Files]], and then later in the main comic in [[1380: Manual for Civilization]], with the books being the actual manual...&lt;br /&gt;
