How best to describe the addition of dimensions? The admirable first author goes as far as the second row, but there appear to be more... ahem... 'depths'. The first is 'sideways', though from this non-playing angle it's depthways; the second adds verticality; the third initially looks to be '4d represented in 3d' perspective (now further represented in 2d, by perspective method), but the sole cube atop confuses me; the fourth is... busy... and seems to go with a hyper(hyper)cubic continuation.

not quite what is demonstrated in the comic but there is a game called 5 dimensional chess with multiverse time travel --[[Special:Contributions/172.68.57.189|172.68.57.189]] 19:00, 19 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think this would require 5 dimensions rather than 4 as the middle rows are 4d slices of a 5d space just as the second row is a 2d slice of a 3d space&lt;br /&gt;

:I see it as there being a basic 1D between the opponents. On the Nth row away from you (on your half of the board) there's an additional N lateral dimensions. Row 1, sideways (8 columns). Row 2, sideways and up/down (7 levels). Row 3, those plus some form of superimposition indicated by scale/perhaps a sub-gridlevel elevation (6 of these?). Row 4, all those plus ??? (gonna assume 5). (...Row 5=Profit?) [[Special:Contributions/162.158.158.131|162.158.158.131]] 22:25, 19 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Is there an error on the top board of this image?  If I look at the sequence of squares on the vertical, they alternate black/white except for the top board.  Even if I were missing some aspect of the logic, I feel like there should be some symmetry between top and bottom. [[Special:Contributions/108.162.221.70|108.162.221.70]] 20:52, 19 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
Note that white made a horse move on the left side of the board, forward one and up two [[Special:Contributions/172.68.57.189|172.68.57.189]] 21:11, 19 May 2021 (UTC)&lt;br /&gt;
:There's at least one black piece on (its) row 3, possibly a knight, and both players have at least one of their pieces on (their) row 4. There are four obvious white pieces forward of the two starting ranks (with no obvious sign that these are established starting positions in this esoteric board*) so there may be a third black piece out there, obscured from clear view. Or more likely that black Knight's movement (two squares forward, three up, one sideways and 0+ squares in the fourth-way direction) is multiple moves (2f1u then 2u1s would be the most simple projected moves).&lt;br /&gt;
:(* - The starting ranks appear to be as per 2D chess, with white's far bishop no longer in starting position, but if that's the one now in the nearest start-level 4th rank then it must not have made just one single 2D-like bishop's move to get there, nor is it obviously a pawn brought forward (2f starter then 1f second move, with or without an en-passant), so it may not be quite so simple, or else we've seen more than 4 white moves (and 3/4 black ones). Or both plus some possible exchange of pieces already.) [[Special:Contributions/162.158.158.131|162.158.158.131]] 22:25, 19 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
I interpreted the comic as the first row is normal chess- 2 dimensional. The second row starts the boards above and below- 3d. The third row would be 4d, and the 4th row would be 5d. ----&lt;br /&gt;
&lt;br /&gt;
Pretty sure this is just funny commentary on people making more and more complex variations of chess, Quantum Chess, 4D Chess, 5D chess with time travel etc... but part of me looks at this and goes &amp;quot;that could be a real game... that could actually be a good game.&amp;quot; just me?

&lt;br /&gt;
Looking at this, I note that there seems to be an assumption in the explanation that n-dimensional chess means chess with an unlimited number of dimensions. I believe that what Randall was actually saying with the &amp;quot;N&amp;quot; was &amp;quot;any number N&amp;quot;, not &amp;quot;all numbers N together&amp;quot;, i.e. &amp;quot;The problem with 3, 4, 5, 6, ... , N dimensional chess is&amp;quot;, and that his objection is that you always only get one number for N. His board, of course, is designed to give you as few as two dimensions up to five dimensions available for any particular piece depending upon the row.&lt;br /&gt;
&lt;br /&gt;
True n-dimensional chess, where there are an unlimited number of dimensions, would probably be unplayable by any Turing machine, including, of course, humans. [[User:Geek Prophet|Geek Prophet]] ([[User talk:Geek Prophet|talk]]) 23:58, 19 May 2021 (UTC)&lt;br /&gt;
:If you have an infinite number of dimensions to work with, there is a straightforward means for a king to escape forever - just alternate linear moves with diagonal moves, always away from the opposing pieces, and always along a dimension not previously traversed (there are an infinite number of these, so always one more). Any opposing piece will be one dimension behind, at the very least. [[Special:Contributions/108.162.237.4|108.162.237.4]] 01:45, 20 May 2021 (UTC)&lt;br /&gt;
::That surely only works if you don't end up stuck in an infinitely-dimensioned corner (infinite dimensions but still finite+nonwrapping extent in each dimension).&lt;br /&gt;
::I'm not sure if there's a foolproof way not to find yourself in that corner, by evading through heretofor unused dimensions strictly around the centre of the board (where a finite number of pieces may not be able to coordinate an all-sides trap) but once there a single infinitely-dimensional queen moved one square away from all the relevent edges, protected by some handy rearward piece, could force the endgame.&lt;br /&gt;
::If the king itself is in that one-space-out position (not yet immediately restricted by the edge, ''any'' edge) I ''think'' it can still be considered corralled by a suitably-placed finite smattering of sufficiently-positioned (for their respective powers of projection) pieces, so even if the centre squares are freely dodgable round (which they might not be, if the opposing king is already safely stationed there, denying 3x3x3x...3 spots to the victimised king) there's a potential to be tactically/psychologically forced towards a definitely entrapping position the moment you stray towards any edge.&lt;br /&gt;
::(If the queen/etc is '≤2D in movement, like a 2D queen except throughout the ∞D of choice' (i.e. confined to a planar diagonal), then it may be less potent for a given distance and not be able to project a no-king-may-pass barrier even without confounding pieces, so might not be the key to the corner-shoving tactic. But then the king would surely be 'choose your single plane' too, in the moves available in its attempt to escape.)&lt;br /&gt;
::Boundaryless arenas (including wrap-around finite boards, or at least 'only' 8&amp;lt;sup&amp;gt;∞&amp;lt;/sup&amp;gt; in their infiniteness) might well be trivially always in an escapable position. But I have my doubts even about the fully-wrapping version, as the attacker's 'left behind' pieces may be considered significant danger again as they are then actually ''ahead'' of any king's fleeing move, and the question now is whether the king can still dodge ever-'sideways' against a concerted and sufficiently analytic opponent still with enough (2? 16? However-many-you-can-initially-start-with-on-such-a-board?) pieces of the right kinds.&lt;br /&gt;
::That said, whatever my proficiency with dimensional projections, I'm definitelt rubbish at chess in its standard form. So ICBW. [[Special:Contributions/141.101.98.60|141.101.98.60]] 09:24, 20 May 2021 (UTC)&lt;br /&gt;

It looks like the 3rd row adds a cube on a stack of alternating colored squares, and then the 4th row does something similar with a tesseract.  It gets a little crowded, so hard to be sure. [[User:Orion205|Orion205]] ([[User talk:Orion205|talk]]) 01:36, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
It might make sense to just add a link to chessvariants.com, since there are a surprising number of multidimensional chess variants in existence besides the aforementioned 5D chess with time travel. [[User:JakobWulfkind|JakobWulfkind]] ([[User talk:JakobWulfkind|talk]]) 02:38, 20 May 2021 (UTC)&lt;br /&gt;
: That site's pretty hard to navigate.  Do you know how to enumerate all existing variants of chess that are infinitely dimensioned, or at least &amp;gt;3 dimensioned? Additionally, this is a pretty exciting topic, is there any capacity for the wiki to dedicate additional pages to it?

&lt;br /&gt;
I don't think the explanation really needs anything to do with intelligence. &amp;quot;Fourth-dimensional chess&amp;quot; is lingo for complexity or cunning, so I think the comic is a joke based on that phrase. [[Special:Contributions/172.69.142.50|172.69.142.50]] 05:36, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
I was disappointed that Randall did not include two odd squares - one on either side of the board - for the one-dimensional chess starting point.  Of course since he does things by rows, this would necessarily limit the number of 1D starting points to one per player - and it would break the symmetry of an 8x8x? board and make it tough to pick which piece starts on the 1D row. [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 13:14, 20 May 2021 (UTC)&lt;br /&gt;
:My (nearly) initial thoughts, too. Row0: Square; Row1: Lateral line of squares (7 or 9 wide, to centre?); Row2: Stacked array of squares (7||9 x 5||7?); Row 3: A cube(/tesseract-slice) of oportunities; then Row4 either Row3 from the other side or a further hyper-version (singular, or doubled with anti-Row4, leading onto anti-Row3, etc...)&lt;br /&gt;
:Another thought I had was that every enhanced-Manhattan step from the home-row should lead to additional spread into a new dimension - to keep that consistent arrange for the branches out from each side to 'kiss' exactly in (non-euclidean) perfect contact. As with 2D chess, any four moves away from the back row (not backwards, not the most basic sideways movement) puts you onto the opponent's half. Or make it Euclidean but then it'd be on one ''several'' opponents' 'halves'. [[Special:Contributions/141.101.99.251|141.101.99.251]] 14:54, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
::You can probably get away with the board being exactly a 8-cube of squares; row 0 will be one square, row 1 will be 8 squares, row 2 will be a 2-dimensional mess (triangle?) of squares where each square connects to exactly two row 1 squares, and so on until row 8, which will again be a square. 9-cube works too, though rows 1 and 8 will have to consist of 9 squares instead of 8. --[[Special:Contributions/162.158.63.78|162.158.63.78]] 16:53, 20 May 2021 (UTC)&lt;br /&gt;

Couldn't you play some of the middle parts with components from 5D chess with time traveling and multiverses or whatever it was(forgot the name)? [[User:Sarah the Pie(yes, the food)|Sarah the Pie(yes, the food)]] ([[User talk:Sarah the Pie(yes, the food)|talk]]) 13:53, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
If a king can move to any other space that's the same or adjacent in any dimension, then a king on the fourth or fifth row would have 188 possible moves (80 in its own row, 81 in the other high-D row, and 27 in the adjacent lower-D row). This would probably make it near-impossible to get a checkmate in this situation. Getting trapped between a neighboring (protected) queen and a 2-steps-away king would do it, of course; and you could maybe replace the queen in that arrangement with a combination of pawns and/or bishops, depending on how those generalize; but it seems it would be trivially easy to foresee any of those traps and avoid it. So I think this game would be unwinnable. [[Special:Contributions/162.158.62.95|162.158.62.95]] 18:45, 20 May 2021 (UTC)&lt;br /&gt;
: The king can't invent new dimensions if they're threatened, obviously! 20:15, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
I'm imagining a form of chess, with computer opponents, where players can add new rules so long as the rules are consistent, and there's like a public wiki of rules to draw from.  I'm thinking an infinitely large board where players can invent secret dimensions and move along them [maybe in a limited manner for chess], but if observed or if a player guesses the dimension, the pieces can be found. 20:15, 20 May 2021 (UTC)&lt;br /&gt;
&lt;br /&gt;
My interpretation: the outermost rows are 1D.  Within them, you can only move back and forth within the row.  The next rows are 2D.  Within them, you can move within the row as well as up and down.  The next rows are 3D.  In addition to the previous moves, you can move to different levels on each square.  The innermost rows are 4D.  Within each square, there are two ways to move (which level and which vertical plane).  So obviously I'm not counting moving between the inner and outer rows as an extra dimension, though of course you may.[[User:CityZen|CityZen]] ([[User talk:CityZen|talk]]) 23:09, 20 May 2021 (UTC)&lt;/div&gt;</summary>

		<summary type="html">&lt;p&gt;CityZen: /* Explanation */ It is flat out incorrect to say &amp;quot;resolution has been decreasing&amp;quot;.  The Y-axis scale is not resolution, but rather resolvable size, which is inversely related to resolution.&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1204&lt;br /&gt;
| date      = April 26, 2013&lt;br /&gt;
| title     = Detail&lt;br /&gt;
| image     = detail.png&lt;br /&gt;
| titletext = 2031: Google defends the swiveling roof-mounted scanning electron microscopes on its Street View cars, saying they 'don't reveal anything that couldn't be seen by any pedestrian scanning your house with an electron microscope.'&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Google Earth}} is mapping software provided by Google that allows people to see the Earth from a birds-eye-view perspective. If you zoom in close enough, you can see individual streets – or in this case, a neighborhood.&lt;br /&gt;
&lt;br /&gt;
{{w|Optical resolution|Resolution}} is a term (roughly) representing the scale of the smallest identifiable feature in an image. In the context of terrestrial image mapping, this would correspond to the width of the square occupied by a single pixel in a terrestrial satellite image. In this strip, Randall points out that the resolution of images available to Google Earth has been improving at an exponential rate for the past decade. This is due to the improving quality of satellite imaging technology, as well as integration of additional data sources, such as aerial photography and street-level roaming cameras. Each tick in the scale represents a resolution improvement by three orders of magnitude.&lt;br /&gt;
&lt;br /&gt;
The {{w|Planck length}} is a unit of length and in principle the shortest measurable length, thus making it effectively the &amp;quot;resolution&amp;quot; of our reality. It is around 1.6×10&amp;lt;sup&amp;gt;-35&amp;lt;/sup&amp;gt; m, close to 10&amp;lt;sup&amp;gt;-20&amp;lt;/sup&amp;gt; times the diameter of a proton. The comic shows how the current growth trend in resolution of Google Earth will hit the Planck length around the year 2100, even though such result is currently considered impossible to achieve.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the fact that the trendline predicts an available resolution in the nanometer range by 2031, which would necessitate (using today's technology) the use of {{w|scanning electron microscope}}s to achieve. It also refers to some heat that Google received before about it's vehicle mounted cameras being an invasion of privacy. Google came back saying that nothing the cameras pick up can't be seen by a pedestrian walking by.&lt;br /&gt;

There is a controversy whether 4′33″ (4 mins 33 secs) was the intended duration. The original manuscript is lost, the first performance lasted 4′33″ (and there is a transcript of it with the exact duration of each movement shown), and later editions only show three movements “tacet”.

&lt;br /&gt;
The comic is about the difficulty of the tar program options.&lt;br /&gt;
&lt;br /&gt;
Even if his life depended on it and after years of usage, Bob/Randall could not come up with the right parameters without looking them up. So a situation is shown, where Bob's life depends on coming up with the right parameters:&lt;br /&gt;
&lt;br /&gt;
* It shows an atomic warhead&lt;br /&gt;
* It has a user interface, which requests any valid tar command&lt;br /&gt;
* If it is not entered on the first try within 10s, the bomb is not disarmed and potentially explodes on the spot&lt;br /&gt;
&lt;br /&gt;
Randall has come up with a situation, where the unix guy Bob can be the hero by knowing tar parameters. This is a pipe dream of a geek; nobody cares IRL, if you know tar parameters on the first try.&lt;br /&gt;
&lt;br /&gt;
It is hilarious, that&lt;br /&gt;
* the bomb says in full detail the rules including that you should not cheat and it probably has no means to check whether you cheated. This is no game, but feels like one. In war and love every means is allowed - even cheating; it would also be self-defense for disarming the bomb; Bob and his colleagues are not even considering to cheat.&lt;br /&gt;
* the user has root access to the bomb, shown by the bomb as ~#, the tilde is the home directory, the # signifies super-user rights; even if the available programs prevent the bomb from being shutdown or disabled by a nonintended way, normally no root access is given for users of linux devices during normal usage; and disarming the bomb with official rules is normal usage of a bomb; a root prompt should not be necessary, if the bomb software is designed and configured well; possibly the unix prompt is a simulation for entering an answer&lt;br /&gt;
* Bob shurely needs more than 10s to come. So the bomb will have announced that questions, which require unix knowledge will follow - or has already asked other Unix questions; perhaps after 10s without entering anything a new question comes up&lt;br /&gt;
* this bomb can be disarmed with &amp;quot;common knowledge&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Small notes:&lt;br /&gt;
* The screen looks to be really grayscale (esp. the inverted &amp;quot;TEN&amp;quot;) - not just because of the comic; it has at least 3 colors (black, white, tar gray); it could be that the &amp;quot;TEN&amp;quot; is updated dynamically and is thus inverted&lt;br /&gt;
* The comic is quite black: The screen and the bomb; Randall seldomly uses solid black areas; the bomb is a gloomy topic so it is black like &amp;quot;tar&amp;quot; (pun)&lt;br /&gt;

I think there is a visual double pun in this strip: the bomb disarmed by a tar command is a reference to the [[wikipedia:Tar (computing)#Tarbomb|tarbombs]], but it also looks like the [[wikipedia:File:Tsar Bomba Revised.jpg|Tsar Bomb(a)]]. --[[User:Koveras|Koveras]] ([[User talk:Koveras|talk]]) 08:24, 1 February 2013 (UTC)&lt;br /&gt;

Googling tar commands would definitely take more than 10 seconds, especially considering that Rob did not take his computer. (A smartphone is an option, but...) &lt;br /&gt;

&lt;br /&gt;
== Explanation is not exact ==&lt;br /&gt;
I think the current explantion is missing an important point: the tar commands are not that much difficult. What makes tar complicated is that there are many different implementations. The linux guy knows only gnu tar, but some unices have much different implementations and different commands. &amp;quot;tar --help&amp;quot; is certainly not available on an old hpux, for example. '''That''' make is difficult to type a valid tar command – even more if you don't know the implementation.&lt;br /&gt;

&lt;br /&gt;
I'm a Windows user, so bear with me. Couldn't he type something like &amp;quot;man tar&amp;quot; to get the proper usage of the &amp;quot;tar&amp;quot; command on this particular system? It's a &amp;quot;man&amp;quot; command, so it shouldn't count as a try towards typing a &amp;quot;tar&amp;quot; command. Of course, maybe the bomb would explode if he entered anything else.

:Yeah, all standard Unix installations should have man installed.  But many mini installations don't, so these days Google is the standard backup.[[User:CityZen|CityZen]] ([[User talk:CityZen|talk]]) 14:58, 1 February 2013 (UTC)&lt;br /&gt;
&lt;br /&gt;
Randall's joke is spot on, as usual. I've been using UNIX for nearly 30 years. Windows User's solution is elegant. Before Google there was the &amp;lt;code&amp;gt;man&amp;lt;/code&amp;gt; command. In all seriousness, productivity on a UNIX box can be greatly enhanced simply by keeping good notes. I keep patterns of all sorts of UNIX commands handy so I don't have to look them up. As Wikipedia implies, &amp;lt;code&amp;gt;tar -tf&amp;lt;/code&amp;gt; (I prefer &amp;lt;code&amp;gt;-t&amp;lt;b&amp;gt;v&amp;lt;/b&amp;gt;f&amp;lt;/code&amp;gt;) should be memorized because one quickly learns that one should ''always'' inspect tarballs before unpacking them. ''– [[User:Tbc|tbc]] ([[User talk:Tbc|talk]]) 14:11, 1 February 2013 (UTC)''&lt;br /&gt;
&lt;br /&gt;
One of the reasons that tar is so useful is that it can often do exactly what you want when other, more obvious commands cannot.  For instance, recursively copying a directory from one place to another (using &amp;quot;cp&amp;quot;) can be tricky when symbolic links are involved, and thus people memorize incantations like &amp;quot;tar cf - . | (cd dest; tar xf -)&amp;quot;.  As well, it's a standard tool that's guaranteed to be found on every Unix installation (unlike zip/unzip).[[User:CityZen|CityZen]] ([[User talk:CityZen|talk]]) 14:58, 1 February 2013 (UTC)&lt;/div&gt;</summary>

&lt;div&gt;Of course with '''''vertical''''' mirror vertical axis is selected: perceived switching of left and right (really close with far to mirror surface).  When '''standing on''' '''''horizontal''''' mirror we will perceive switching bottom from top. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 09:09, 10 December 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
You're certainly correct, but I think that the original question is not really asking about text (or other things) which are perpendicular to the mirror, but rather text which is parallel to it (and thus the close vs. far doesn't come into it).  For example, when reading signs in your rear view mirror or holding a book in front of your chest while looking in a mirror.  I've added a little bit to the explanation to attempt to help clarify what's happening in that situation.  I'm not sure if it really helps or not.

&lt;br /&gt;
Easier way to describe it: Imagine you hold a piece of glas. Write on the glass and hold it in front of the mirror, so that you can see both the original text and the mirrored text. Both versions of the text will look identical. So the mirror doesn't change anything. [[Special:Contributions/62.220.2.194|62.220.2.194]] 11:10, 10 December 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
Another way: draw a line between the real object and its reflection.  Things are reflected around that line.  If that line is going up &amp;amp; down (relative to your eyes), then things are reflected left/right (relative to your eyes).  If that line is horizontal (again relative to your eyes), then things are reflected top/bottom.  So it's not so much whether the mirror is horizontal or vertical, but rather what direction you are looking into the mirror (although that can be influenced a lot by the mirror's orientation).[[User:CityZen|CityZen]] ([[User talk:CityZen|talk]]) 04:17, 11 December 2012 (UTC)&lt;br /&gt;

I always wonder: Since the sky goes from red to blue to red and the optical spectrum goes from red to green to blue. How come the sky is never green?&lt;br /&gt;
: Because of human color perception. You only perceive green in polychromatic light when said light is stronger in the middle wavelengths than the low or high wavelengths; in other words, you would need a process in the sky that removed ''both'' the high and low wavelengths from white light. As the sun sets, only the lower wavelengths are removed, so you perceive yellows and reds -- this perception of color is &amp;quot;one-sided&amp;quot;, i.e. it is not interfered with by even longer wavelengths. By the way, sometimes you do see green briefly in the sky, it's called a [http://en.wikipedia.org/wiki/Green_flash Green Flash]. --[[User:Prooffreader|Prooffreader]] ([[User talk:Prooffreader|talk]]) 16:41, 10 December 2012 (UTC)&lt;br /&gt;

==Explanation==&lt;br /&gt;
A {{w|Faraday cage}} is a cage of conducting material that interferes and blocks out {{w|electromagnetic radiation}} like cell phone signals (provided the material is of the appropriate thickness and the gaps between &amp;quot;bars&amp;quot; are significantly smaller than the wavelength of the radiation). A {{w|cage match}} is a form of wrestling in which the two participants are held in a hexagonal cage and left to fight each other. The comic caption is a play on the two terms, putting [[Cueball]] into a cage match in the faraday cage that is blocking his reception.&lt;br /&gt;
&lt;br /&gt;
The title text is a play on a rule in cage matches that states that a participant wins if they can escape the cage.  {{w|Tunneling_diode|Tunneling diodes}} are capable of fast operation, allowing a device to generate high frequency signals, which are more capable of penetrating the mesh openings in a Faraday cage.  The statement is one you might hear in a bad science fiction movie, since it includes a kernel of truth in a casserole of nonsense.&lt;br /&gt;

:: +1 on '''s/Randall/Cueball/g''' (and '''s/(girlfriend|partner|wife)/Megan/gi''') with an explanation that the comic very likely depicts real-world events in Randall's and (real-world) Megan's life.  Though it might be tributary to make the inferential leap, I think would be entirely &amp;quot;unscientific&amp;quot; to do so (which is so ''un''Randall...)

::::Crying out about social injustice is the adult version of screaming &amp;quot;Ouch!&amp;quot; when a parent grabs a child's arm to get their attention. Democracy is not do-what-you-want-to. Democracy is having a discussion and then acting upon the results of that discussion. There have been [[explain_xkcd:Community_portal/Proposals#Randall_in_Comics|many]] [[Talk:1117:_My_Sky|discussions]] about having Randall in comics. The result was that whenever Randall decides to place himself in a comic, that we should honor that. So, instead of using a generic character he put himself and his wife into the comic. So, we honor that. We do not know the name of his wife, Randall is a very private person, we respect his privacy and only go by the information he gives out, and we don't make wild speculations, this is why we don't refer to her by (any) name; it's the most respectful thing we can do.&lt;br /&gt;
&lt;br /&gt;
::::To prevent vigilante edit warring I've locked the page. Now, if you think that the site should not recognize when Randall specifically puts himself in comics, then there is a reason to bring this discussion back to the table.

== Explanation ==&lt;br /&gt;
&lt;br /&gt;
This comic marks the second year of [[Randall Munroe]]'s wife's battle with cancer, and appears to depict actual events from those two years.&lt;br /&gt;
Keeping with tradition, we will refer to Randall's character as [[Cueball]] and his wife's as [[Megan]].&lt;br /&gt;
&lt;br /&gt;
Some explanations:&lt;br /&gt;
* Panel 1: Megan receives a diagnosis over the phone as Cueball sits by her side supportively.&lt;br /&gt;
* Panel 2: Megan undergoing IV (intravenous) {{w|chemotherapy}}. Because of the hair loss that results from chemotherapy, many patients opt to shave their heads when they undergo chemotherapy. Her hair grows back over the course of the following panels.&lt;br /&gt;
* Panel 3: The two of them spending time alone together. &lt;br /&gt;
* Panel 4: The couple are waiting for the results of a scan. A phone sits on the middle of the table while they wait for it to ring.&lt;br /&gt;
* Panel 5: More chemotherapy. The couple are playing {{w|Scrabble}}, in which players use letter tiles to spell words in a cross-word style. Megan uses the fact that she has cancer as leverage to get Cueball to ignore the fact that the word she has played (zarg) is not a real word.&lt;br /&gt;
* Panel 6: Someone suggests they come for a visit next year, but all they can think about are the words &amp;quot;next year&amp;quot;, indicating that they know the future is very much in doubt. &lt;br /&gt;
* Panel 7: They get married.&lt;br /&gt;
* Panel 8: The couple watching humpback whales.&lt;br /&gt;
* Panel 9: Cueball is paraphrasing a line from the song &amp;quot;{{w|Still Alive}}&amp;quot; ([http://www.youtube.com/watch?v=l_S0PGu-cH4 video]) from the video game ''{{w|Portal}}'' (''&amp;quot;I'm doing science and I'm still alive&amp;quot;'').&lt;br /&gt;
* Panel 11: Cueball and Megan have dinner to celebrate the fact that she has made it two years since her {{w|biopsy}}.&lt;br /&gt;
The title text is referring to a possible side-effect of chemotherapy drugs, the {{w|Chemotherapy#Neurological adverse effects|inability to concentrate}}.&lt;br /&gt;

== Explanation ==&lt;br /&gt;
&lt;br /&gt;
This comic marks the second year of [[Randall Munroe]]'s wife's battle with cancer, and appears to depict actual events from those two years.&lt;br /&gt;
Keeping with tradition, we will refer to Randall's character as [[Cueball]] and his wife's as [[Megan]].&lt;br /&gt;
&lt;br /&gt;
Some explanations:&lt;br /&gt;
* Panel 1: Megan receives a diagnosis over the phone as Cueball sits by her side supportively.&lt;br /&gt;
* Panel 2: Megan undergoing IV (intravenous) {{w|chemotherapy}}. Because of the hair loss that results from chemotherapy, many patients opt to shave their heads when they undergo chemotherapy. Her hair grows back over the course of the following panels.&lt;br /&gt;
* Panel 3: The two of them spending time alone together. &lt;br /&gt;
* Panel 4: The couple are waiting for the results of a scan. A phone sits on the middle of the table while they wait for it to ring.&lt;br /&gt;
* Panel 5: More chemotherapy. The couple are playing {{w|Scrabble}}, in which players use letter tiles to spell words in a cross-word style. Megan uses the fact that she has cancer as leverage to get Cueball to ignore the fact that the word she has played (zarg) is not a real word.&lt;br /&gt;
* Panel 6: Someone suggests they come for a visit next year, but all they can think about are the words &amp;quot;next year&amp;quot;, indicating that they know the future is very much in doubt. &lt;br /&gt;
* Panel 7: They get married.&lt;br /&gt;
* Panel 8: The couple watching humpback whales.&lt;br /&gt;
* Panel 9: Cueball is paraphrasing a line from the song &amp;quot;{{w|Still Alive}}&amp;quot; ([http://www.youtube.com/watch?v=l_S0PGu-cH4 video]) from the video game ''{{w|Portal}}'' (''&amp;quot;I'm doing science and I'm still alive&amp;quot;'').&lt;br /&gt;
* Panel 11: Cueball and Megan have dinner to celebrate the fact that she has made it two years since her {{w|biopsy}}.&lt;br /&gt;
The title text is referring to a possible side-effect of chemotherapy drugs, the {{w|Chemotherapy#Neurological adverse effects|inability to concentrate}}.&lt;br /&gt;

== Explanation ==&lt;br /&gt;
&lt;br /&gt;
This comic marks the second year of [[Randall Munroe]]'s wife's battle with cancer, and appears to depict actual events from those two years, though this type of progression could be common in many couples' experiences. Randall's wife's cancer has been the subject of [[:Category:Cancer|several previous comics]].&lt;br /&gt;
&lt;br /&gt;
Some explanations:&lt;br /&gt;
* Panel 1: Randall's wife-to-be (at that point) receives a diagnosis over the phone as Randall sits by her side supportively.&lt;br /&gt;
* Panel 2: Undergoing {{w|chemotherapy}} through an IV. Because of the hair loss that results from chemotherapy, many patients opt to shave their heads when they undergo chemotherapy. Her hair grows back over the course of the following panels.&lt;br /&gt;
* Panel 3: The two of them spending time with one-another, and no one else. This is very important for couples in a situation like that. Nature is a good resort for many, as long as health permits.&lt;br /&gt;
* Panel 4: The couple are waiting for the results of a scan; it appears a phone is on the middle of the table that they are waiting to ring.&lt;br /&gt;
* Panel 5: More chemotherapy. The couple are playing {{w|Scrabble}}, as referenced in the title text, which is a very popular board game in which players use letter tiles to spell words in a cross-word style. She uses the fact that she has cancer as leverage to get Randall to ignore the fact that the word she has played (zarg) is not a real word.&lt;br /&gt;
* Panel 6: Someone suggests they come for a visit next year, but all they can think about are the words &amp;quot;next year&amp;quot;, suggesting their fears that they won't be able to go anywhere, or that one of them might even be dead by next year.&lt;br /&gt;
* Panel 7: Randall and his fiancé get married.&lt;br /&gt;
* Panel 8: The couple watching humpback whales. See panel 3.&lt;br /&gt;
* Panel 9: Randall is paraphrasing a line from the song &amp;quot;{{w|Still Alive}}&amp;quot; ([http://www.youtube.com/watch?v=l_S0PGu-cH4 video]) from the video game ''{{w|Portal}}'' (''&amp;quot;I'm doing science and I'm still alive&amp;quot;'').&lt;br /&gt;
* Panel 11: Randall and his wife have dinner to celebrate the fact that she has made it two years since her biopsy.&lt;br /&gt;
The title text is referring to a possible side-effect of chemotherapy drugs, the [http://en.wikipedia.org/wiki/Chemotherapy#Neurological_adverse_effects inability to concentrate].&lt;br /&gt;

Flip cancer. Lost my mother-in-law to it and now my dad is undergoing chemo for stage IV lung cancer.&lt;br /&gt;
:Seconded. This strip hits close to home, even years after the fact. And given that of my parents and grandparents only one grandmother was not yet diagnosed with any type of cancer, both frequentist and Bayesian statisticians probably agree I should be cautious myself.

&lt;div&gt;In the explanation: &amp;quot;The next three digits are the exchange number (the middle digit being always 2 or higher)&amp;quot;. That cannot be true. After my area code, my exchange number is 504...the middle digit being a zero i.e. &amp;lt;2. Where did you get the information that the middle exchange number has to be a 2 or higher?

I guess this has something to do with keeping your phone number even when switching providers? We got a law in Norway around that time, which says you're able to keep your phone number while switching. Only difference is that here you can only tell, from the first two of eight digits, which ''provider'' you had in 2005 (or whenever it took effect). --[[User:Buggz|Buggz]] ([[User talk:Buggz|talk]]) 08:31, 2 November 2012 (UTC)&lt;br /&gt;

:It probably does.

: According to wikipedia, mobile number portability was implemented in the USA in 2003.11.24. The comic would make sense with 2003, but why 2005? Maybe it only caught on enough in 2005: http://www.pyramidresearch.com/pa_may26_mnp.htm&lt;br /&gt;
&lt;br /&gt;
: One reason for switching to a new &amp;quot;local&amp;quot; number would be so that those who have land lines aren't making &amp;quot;long-distance&amp;quot; phone calls to your cell phone. My brother just recently moved back from the east coast and is keeping his same cell phone number, which doesn't affect my other siblings and myself because we only use cell phones (which only count the number of minutes used). But my mom still uses land lines most of the time and so she's being billed for a long-distance call whenever she calls him, even though he lives about a mile away from her. But since most people are ditching the land lines, I think it'll be a moot point in about 5-10 years. --[[User:Joehammer79|Joehammer79]] ([[User talk:Joehammer79|talk]]) 13:45, 2 November 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
It has to do with cell phones versus land lines. Back in the day (before the early 2000s), many people still had a land line as their primary or only phone. Your phone number's area code would be based on the area in which you lived. If you moved to a new area, you would get a new phone number, and if you moved out of the previous area code, a new area code. But with a cell phone, when you moved you kept the same number, including the area code. This was especially true after the 2003 law made it so you could keep the same number even if you switch your provider. The year 2005 has to do with when many people made their cell phone their primary or only phone. As [http://usatoday30.usatoday.com/tech/news/2003-03-24-cell-phones_x.htm this USA TODAY]article mentions, in 2003 18% of Americans with cell phones considered their cell phone their primary phone. Given the rapid growth of the industry, it is possible that 2005 is when more than half of cell phone owners in America considered their cell phone their primary phone.&lt;br /&gt;
&lt;br /&gt;
:The details differ, of course (&amp;quot;your mileage may vary&amp;quot;).  There are so many possible reasons why this occurs.  My parent's cell phones (612) don't match their home land-line (763) due to area code splits -- they didn't move or cause the disconnect themselves.  As for me, my first cell phone matched theirs, but in 2005 I moved to Michigan (586 area), creating a disconnect.  Then to make things worse, early next year (2006) I got a second line (and new phone) on my new girlfriend's account, and she lived on the other side of the city (734).  We married and moved near where I was living &amp;amp; working, but both still have &amp;quot;734&amp;quot; cell phones for family purposes.  So Randall's &amp;quot;living&amp;quot; can also be &amp;quot;dating / where significant other is living&amp;quot;. --BigMal27 / [[Special:Contributions/192.136.15.149|192.136.15.149]] 15:54, 2 November 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
For anyone from outside the US, the key fact here is that in the US, your mobile phone has an area code the same as a landline. I used to live in the US, and it blew my mind to learn that mobile phones had area codes there. I was like, but.... Huh? That's like saying your car has a postal address.[[User:Carlisle|Carlisle]] ([[User talk:Carlisle|talk]]) 15:06, 2 November 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
:In the US, our cars kind of do have a postal address -- the state they are titled &amp;amp; registered in, the same state emblazoned on the license plate in the back (and sometimes the front also).  However, the states don't like it when you operate an &amp;quot;out-of-state&amp;quot; car in their territory for too long.  Specifically, you are using public roads that you are not paying for.  Then, when you transfer title and are assigned a new plate, you get a new letter/number combination.  License plates -- and specifically the random ID (or &amp;quot;vanity plate&amp;quot; custom ID) they hold -- are not portable between states. --BigMal27 / [[Special:Contributions/192.136.15.149|192.136.15.149]] 15:47, 2 November 2012 (UTC)&lt;br /&gt;

::In the past, in Italy you had to do the same when you moved from one province to another. Now, if you move, you pay car taxes to a different province, but your license plate stays the same. At the time, the province code was part of the license number, now it isn't anymore. If you have an old plate with a province code, you keep it even if you move.&lt;br /&gt;

&lt;br /&gt;
::In the UK the first two letters on a car's plate are for where it was registered, but after that they may as well be meaningless, you do see more S plates in Scotland, M plates in Manchester etc. but the letters don't always even indicate the car was bought as new in that place, I take photos for car dealers and you often see new cars for sale with plates from other parts of the country. Still, actually being able to post to a car would be funny.&lt;br /&gt;
::On the subject of postal addresses, I had an Irish friend at uni, and when we were exchanging addresses to write to each other at the end of first year he gave his address as (not his real name, obviously) Sean Murphy, Kilbeggan, Ireland. We all laughed but he said, the postman knows who everyone is so they don't need street names and numbers, we asked what if they got a new postman, and he said 'that wouldn't happen'.[[User:Carlisle|Carlisle]] ([[User talk:Carlisle|talk]]) 23:10, 4 November 2012 (UTC)&lt;br /&gt;

I'm 34 and live in the USA and it still took me a while to understand this.  The 2005 date is because even though the portability law was passed in 2003, it was still difficult to do and not very common to keep you number until 2005.&lt;br /&gt;

I think title text refers to the expansion of the universe and the speed of light.  The observable universe is viewed from light that originated in the past.  The further away the object, the further back in time we observe it.  In an expanding universe, the universe we observe today is actually how it looked in the past (smaller) and we are unable to observe it's present size (larger) due to the great distances and the time it takes for the light to arrive.  Thus, the universe is larger than it appears, no matter if you view it traveling towards or away from any object.  --[[User:Bpiltz|Bpiltz]] ([[User talk:Bpiltz|talk]]) 15:47, 24 October 2012 (UTC)&lt;br /&gt;

The ACTUAL reason he says &amp;quot;Universe is larger than it appears&amp;quot; is because Edwin Hubble was part of the &amp;quot;Great Debate&amp;quot;, which was a scientific conundrum in the early 20th century about whether the universe contained multiple galaxies or merely the Milky Way. Scientists were uncertain which theory was correct until Hubble's data, which conclusively showed, via observations of Cepheid variable stars, that galaxies such as Andromeda are located much too far away (about 2 million light years) to be located within our own galaxy. Consequently, the universe is much larger than it might originally appear to be. &lt;br /&gt;

The ACTUAL reason he says &amp;quot;Universe is larger than it appears&amp;quot; is because Edwin Hubble was part of the &amp;quot;Great Debate&amp;quot;, which was a scientific conundrum in the early 20th century about whether the universe contained multiple galaxies or merely the Milky Way. Scientists were uncertain which theory was correct until Hubble's data, which conclusively showed, via observations of Cepheid variable stars, that galaxies such as Andromeda are located much too far away (about 2 million light years) to be located within our own galaxy. Consequently, the universe is much larger than it might originally appear to be. &lt;br /&gt;

&lt;div&gt;Perhaps his motivation is to restore natural wind patterns to the environment. I remember reading about the ecological impact of wind power includes lessened wind currents. Some organisms rely on the wind to propagate the species, such as winds that blow seeds or how some spiders &amp;quot;parachute&amp;quot; on wind currents. Or it could be that he just likes to mess with people. --[[User:Joehammer79|Joehammer79]] ([[User talk:Joehammer79|talk]]) 13:46, 10 October 2012 (UTC)&lt;br /&gt;

Am I the only one who is also entertaining the possibility that the fan setup in the picture is not acting with, but rather counteracting the wind, which is turning the windmill that supplies it power? I understand that the alt-text makes it seem like Munroe's thinking about 'making up' for our interference with insolation (and presumably wind, water etc.) patterns. But, if we're going to bring in logic here, EVERYTHING falls apart :D I had a little fun trying to model what kind of a dynamic equilibrium the hitherto described windmill-fan arrangement would settle into.

Traffic signals really are one of the most inscrutable inventions to ever be made. I mean, red means stop, yellow means caution, green means go. Unless you're in a turn lane, which means you have to watch for the green arrow, if there is one, or wait for an opening. Unless you're turning right, which is permitted to turn at any time providing there aren't any cars. Unless there's a sign that says &amp;quot;No Right Turn On Red&amp;quot;. There's also the crazy cities that have special right turn lights. Then there's the intersections that have a sign for each lane telling what can and cannot be done. Or, if you're really lucky one of those intersections that has the LED screen that dynamically changes what the lane can and cannot do. And to top it all off, the Colorado Department of Transportation (as well as a few other states I'm sure) are testing out a 4-stage left turn light to increase the safety of drivers. [https://www.auroragov.org/cs/groups/public/documents/document/003604.pdf] Yes, you read that pamphlet correctly. There is a special 4th light, just to blink yellow, because you couldn't just make the yellow light blink, like it does anyway after 9pm. No. There has to be a whole special light that indicates when a left-turn-er must use special caution to turn.&lt;br /&gt;
&lt;br /&gt;

: There is a problem with a blinking yellow arrow.  Blinking yellow is already used.  It means you have the right of way, but the other direction may proceed as well.  What is wanted here is blinking red, which means that you stop, but may proceed, as someone else has the right of way.  As for adding a fourth light, this just confuses things even more, particularly with respect to color blind individuals.  Having said that, Virginia's variant is to have lights with both left arrows and solid greens.  If it is green arrow, you have the right of way, while solid green means the other direction also has a green.

::so the blinking yellow left arrow generally means the same as a round green light - you can go when it's clear, but the opposite traffic has a green light too. I love this idea because a lot of the time where there is a separate left-turn signal, there are advanced lefts for both ways, and then left turners get a red left arrow and have to stop while people going straight get a green - so even where there's no oncoming traffic, you can't turn. this way, you just lose your &amp;quot;advance&amp;quot; status and go back to the regular rule of &amp;quot;turn if you can, otherwise you end up turning as the lights go yellow&amp;quot;&lt;br /&gt;
&lt;br /&gt;
::I think what Lcarsos is pointing out if you check the PDF link, is that the new left-turn lane has 4 lights, all of which are left-arrow shaped. Thus, his point is why couldn't they make the 2nd light (yellow left arrow) blink, instead of installing a third light which is also a yellow left arrow whose job is to blink?&lt;br /&gt;
&lt;br /&gt;
::I can think of a few possible reasons - first, perhaps an all-blinking light has different bulbs which are more efficient for blinking and won't burn out as much; second, because they want to distinguish between the two lights more strongly (i.e. if you glance over between blinks, you don't have to wait a moment to see if it will blink - if you see the 3rd light up, you know it's going to blink without waiting for it to actually blink); similarly, I suppose there could be colour blindness issues where they want to make it clear which light is which.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1114&lt;br /&gt;
| date      = September 28, 2012&lt;br /&gt;

| imagesize =&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
The comic explains how weapons would really behave if they were made out of unusual materials. In fantasy stories, using unusual materials for weapons traditionally makes the weapons more powerful and cooler despite limited explanation for exactly why materials of extraterrestrial origin are so superior to their earthen counterparts.&lt;br /&gt;
&lt;br /&gt;
On the other hand, iron from meteorites was often mixed with &amp;quot;terrestrial&amp;quot; iron in the early stages of human development to create relatively high quality steel for swords. Undeveloped metalworking techniques at the time meant that extraterrestrial metal was often more refined and plentiful than man-made metal ingots.[http://www.sciencedirect.com/science/article/pii/0016703767901408 Research] has shown that meteorites have an abundance of the chemical element Antimony (Sb) which by itself is a very brittle metal and therefore swords forged from metals harvested from meteorites are not as strong as lore may make one think. &lt;br /&gt;
&lt;br /&gt;
The second panel is a reference to stories set in Middle Earth and the sword is Sting, which glows blue when Orcs are near. Sting used to belong to Bilbo Baggins, when he grew old he gave it to Frodo Baggins as a gift. The dagger in question, though, glows because of the radioactive properties of Actinium (Ac) which is also highly toxic. Definitely not a dagger you would want to carry around for your every day battles.&lt;br /&gt;
&lt;br /&gt;
The word &amp;quot;Eldritch&amp;quot; in the third panel means sinister, or ghostly.&lt;br /&gt;
&lt;br /&gt;
The fourth panel mentions that the weapon gives a +2 to a player's attribute. This is a reference to role-playing games in which it is common to find items that are able to improve one's character by increasing desirable attributes.  In this case, however, +2 to cancer risk would definitely not be considered a desirable attribute to increase.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

| titletext = This exotic blade was wrought from a different fallen star. The meteorite was a carbonaceous chondrite, so it's basically a lump of gravel glued into the shape of a sword. A SPACE sword!&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
The comic explains how weapons would really behave if they were made out of unusual materials. In fantasy stories, using unusual materials for weapons traditionally makes the weapons more powerful and cooler despite limited explanation for exactly why materials of extraterrestrial origin are so superior to their earthen counterparts.&lt;br /&gt;
&lt;br /&gt;
On the other hand, iron from meteorites was often mixed with &amp;quot;terrestial&amp;quot; iron in the early stages of human development to create relatively high quality steel for swords. Undeveloped metalworking techniques at the time meant that extraterrestrial metal was often more refined and plentiful than man-made metal ingots.[http://www.sciencedirect.com/science/article/pii/0016703767901408 Research] has shown that meteorites have an abundance of the chemical element Antimony (Sb) which by itself is a very brittle metal and therefore swords forged from metals harvested from meteorites are not as strong as lore may make one think. &lt;br /&gt;
&lt;br /&gt;
The second panel is a reference to stories set in Middle Earth and the sword is Sting, which glows blue when Orcs are near. Sting used to belong to Bilbo Baggins, when he grew old he gave it to Frodo Baggins as a gift. The dagger in question, though, glows because of the radioactive properties of Actinium (Ac) which is also highly toxic. Definitely not a dagger you would want to carry around for your every day battles.&lt;br /&gt;
&lt;br /&gt;
The word &amp;quot;Eldritch&amp;quot; in the third panel means sinister, or ghostly.&lt;br /&gt;
&lt;br /&gt;
The fourth panel mentions that the weapon gives a +2 to a player's attribute. This is a reference to role-playing games in which it is common to find items that are able to improve one's character by increasing desirable attributes.  In this case, however, +2 to cancer risk would definitely not be considered a desirable attribute to increase.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Cueball and Megan are in a weapon store talking to a bearded salesman wearing a hat.]&lt;br /&gt;
&lt;br /&gt;
:[Salesman holds up a sword]&lt;br /&gt;
:Salesman: This sword was forged from a fallen star. Antimony impurities make the blade surpassingly ''brittle'' and ''weak''.&lt;br /&gt;
&lt;br /&gt;
:[Salesman holds up a dagger]&lt;br /&gt;
:Salesman: And this dagger is made of metal from a far-off kingdom. It glows blue.&lt;br /&gt;
:Off-panel: When orcs are near?&lt;br /&gt;
&lt;br /&gt;
:Salesman: No, always. Radiation from the Actinium content.&lt;br /&gt;
:Megan: ...Does it have eldritch powers?&lt;br /&gt;
&lt;br /&gt;
:Salesman: It gives the wearer +2 to cancer risk.&lt;br /&gt;
:Cueball: I think we should find another shop.&lt;br /&gt;

&lt;div&gt;&amp;quot;extraterrestrial metal was often more refined and plentiful than man-made metal ingots.&amp;quot; -I'd love to read about this. Citation needed! --[[User:Buggz|Buggz]] ([[User talk:Buggz|talk]]) 08:59, 28 September 2012 (UTC)&lt;br /&gt;
:Sure. Wikipedia. https://en.wikipedia.org/wiki/Iron_meteorite. It was mostly cultures with little industry picking up meteorites and finding that the stuff lying on the ground was miles better than the awful fragile metal that they were making from rocks.

&lt;br /&gt;
In fantasy stories, the world is usually much more complicated place. Meteorite, which may have easily traveled billions kilometres going through places with environment greatly different from anything available on the planet, can easily develop interresting properties. Still, for every super-cool super-effective sword, there must be many other meteorites whose properties make them LESS usefull for weapons.&lt;br /&gt;
Even in our universe, meteorites may went through temperatures and magnetical fields much greater that available for preindustrial civilization. -- [[Special:Contributions/89.177.52.2|89.177.52.2]] 10:42, 28 September 2012 (UTC)&lt;br /&gt;

That salesman was likely to sell a flashlight as a lightsabre.--[[User:DelendaEst|DelendaEst]] ([[User talk:DelendaEst|talk]]) 11:20, 28 September 2012 (UTC)&lt;br /&gt;
&lt;br /&gt;
It is possible that Randall drew inspiration from the piece of news that was making rounds yesterday, best exemplified by an article in The Register titled [http://www.theregister.co.uk/2012/09/27/tibetan_alien_statue_discovered_by_nazis/|Tibetan STATUE found by 1930s NAZI expedition is of ALIEN ORIGIN].  Many publications ran a similar headline, stating that the statue, and not the material it is made from, is of extraterrestrial origin.

&lt;br /&gt;
The explanation should perhaps also address how in various computer/fantasy games one will often come across a weapons dealer, a non-player character who will happily sell you whatever he has in stock.
