Editing Talk:2082: Mercator Projection

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->

The choice of characters in this comic is...interesting. I never got the impression that White Hat was gullible. [[User:GreatWyrmGold|GreatWyrmGold]] ([[User talk:GreatWyrmGold|talk]]) 21:27, 7 December 2018 (UTC)

I can convince people that all of Randal's maps are real? [[User:Linker|Linker]] ([[User talk:Linker|talk]]) 00:53, 8 December 2018 (UTC)

But wait, how does driving north reach Alaska? I thought it was an island near Hawaii to the southwest. More seriously, should we mention that the Mercator does have useful properties such as preserving angles or is that too much for explaining the comic?

People putting a joke in the incomplete tag but completely ignoring the “Please mention here why this explanation isn't complete.” part is really annoying [[User:DrMeepster|DrMeepster]] ([[User talk:DrMeepster|talk]]) 07:38, 8 December 2018 (UTC)
:Good Dr. It is an autobot that fills in the first page of the explanation, and here it is always clearly incomplete. Others may later delete that it is a bot that has made the explanation, but not knowing if it is complete, but also now knowing if it is not. And then there is the large text stating do not delete too soon. So I agree that reasons should be given for old comics that are suddenly listed as incomplete, but that the newest comic is listed as incomplete is just basic info ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 18:29, 9 December 2018 (UTC)
::Why doesn’t the autobot explicitly say that it is incomplete by virtue of being a new comic? [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 19:54, 9 December 2018 (UTC)

Perhaps it should elaborate on "ridiculous" i.e. Cueball claims that the Mercator projection changes the topology of land and water masses, not just their relative size and (oh it's a long time since I did maths, so I'll call it) squishiness.

Mercator map projection has the advantage that shortest line between two points on Earth (on globe) is straight line in this projection. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 11:17, 8 December 2018 (UTC)

The largest islands in Lake Ontario are either the western parts of the Thousand Islands or the southern-most part of the City of Toronto.  Neither would be considered "in the middle" of the lake.  While Lake Erie has some islands in the middle, like Middle Island, Lake Ontario does not have similar navigation targets/hazards.

Both the XKCD comic (in its caption) and the explanation (in its current form) misuse the word "fact."  The point that Randall is trying to make is that you can convince people of '''lies''' or anyway '''mistaken ideas''' by referring to the Mercator projection.  '''Facts''' are by definition correct.

::Facts can also be anything ''presented'' as objectively real. Under that definition, this is proper usage. [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 20:02, 9 December 2018 (UTC)
:: Falsehoods presented as fact are facts only in the mind of someone like Trump. For the rest of us, Canada as an island is not a fact. Does still count as a factoid though; they by definition may only look like facts, and may or may not be true. [[Special:Contributions/162.158.38.106|162.158.38.106]] 17:01, 15 April 2020 (UTC)

I wonder if it is possible to make a map projection stupid enough to support this at first glance. [[User:Saklad5|Saklad5]] ([[User talk:Saklad5|talk]]) 20:05, 9 December 2018 (UTC)

-:White Hat is just a fill in character as Cueball so he can both be one way or the opposite. Definitely not like Black Hat or Beret Guy. I have added an example of Cueball spreading misinformation in the explanation, and also here it is White Hat that is the victim, just to show that your statement is not generally valid for White Hat. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 12:35, 10 December 2018 (UTC)

-::I'm afraid you are mistaken. A straight line on Mercator translates to a {{w|rhumb line}}, not a {{w|great-circle distance|great circle}}. Rhumb lines are useful for navigation, more so than great circles if all you have is a compass, but they are not (necessarily) the shortest distance between two points.

-: You could probably do it with a janky Peirce quincuncial that's not centered on the North Pole. [[Special:Contributions/172.68.59.108|172.68.59.108]] 15:05, 10 December 2018 (UTC)
-The trivia should be merged with the main explanation. The fact that a projection can't erase a border, such as the land border between the US and Canada, is an important part of the joke. -[[Special:Contributions/108.162.238.161|108.162.238.161]] 06:33, 10 December 2018 (UTC)
