In this comic, Randall returns to one of his pet subjects: map projections. Unusually, this time it is from the perspective of people living - or, in this case, sailing - upon the world that is quite literally being mapped.

Two sailing ships, of circa 19th century design, are engaged in a close chase across the Atlantic, the aggressor flying the Skull And Cross-Bones of a stereotypical pirate vessel. The ship being chased, however, has a plan to escape. And the means to do so. At a crucial moment, Cueball is told to flip an incongruous large switch that (like several other artefacts in Randall's universe) alters the nature of their reality.

Whereas beforehand the world is directly represented upon a simply contiguous map, the {{w|Robinson projection}p, it is now changed to a one (which is actually the new reality) known as Goode Homolosine in which the flattening of the world mitigates localised warping of angle/distance/area by introducing discontinuities in relatively 'unused' parts of the mapped world, such as the centre of the Atlantic.

By precisely timing the change (as they cross a particular meridian, possibly the 40°W one), the pursuer now finds themselves on the wrong side of the very real gap, allowing the pursued ship to escape whatever fate they were trying to avoid. Though there is still an oceanic connection, it requires sailing down the edge towards the tropics, rounding this particular rent in the planet's surface and heading back up the other side. This is vastly further than Cueball's ship needs to travel to reach (presumably) any European port in which they can safely moor.

The title text elaborates on the policies of the black-flagged ship: crewmates are never to look into the "projection abyss" and to never hit the button labeled "DYMAXION." The first rule suggests that changing the projection of physical reality produces a gap in reality, a void. This may be dangerous to gaze into or simply unnerving to crewmates, hence the rule. The second rule references a button that seems to do the same thing as the lever but changes the world into a Dymaxion map. The Dymaxion projection is somewhat notorious for projecting the globe of the Earth in a manner that creates sections of triangles in the effort to preserve land scale as much as possible, bucking the trend of most map projections causing land masses and their sizes relative to each other becoming warped, and therefore inaccurate. However, the formation is strange and somewhat mind-bending, so turning the world into a Dymaxion projection may be bad. This would be cause for creating a rule against pressing the button in question.

Discussion

The flag on the lefthand ship (port-side, if you will :P) looks like the Rising Sun Flag that the Japanese Navy uses as its ensign. 172.70.110.147 02:31, 5 February 2022 (UTC)

Actually, that the Navy used in 1889 (not uses). 172.70.110.147 02:31, 5 February 2022 (UTC)

I reckon it looks more like a Jolly Roger. 108.162.249.87 02:44, 5 February 2022 (UTC)

Ah, you're right. I was thinking Union Jack for a minute but thought there were too many streaks. The upper and lower portions of the skull nearly touch the edge of the flag, making it look like something akin to a sunburst. 172.70.114.99 02:46, 5 February 2022 (UTC)

If you look at the 2x size image and zoom in it is very clearly the Skull and Crossbones flag from pirates. Which makes a lot of sense. --Kynde (talk) 17:27, 13 February 2022 (UTC)

Okay, I added an initial description for the title text and made a bunch of edits. I'll stop now to let other people get in on the action. :P 172.70.114.99 02:54, 5 February 2022 (UTC)

Yeah, I kept edit-conflicting (except the first time, when I ended up just appended to some else's first edit) and I think I have reached the point where I've unruined everything of everyone else's that I didn't fully intend to change or add to. But it's late (GMT) and I need my sleep so if I've accidentally rushed through some stuff I shouldn't have then please fill your boots and tweak it back (or onwards) to how it should be. G'night! 162.158.159.11 03:07, 5 February 2022 (UTC)

G'night. I think we were conflicting. It was my first experience live editing and it was fun. lol 172.70.230.157 03:08, 5 February 2022 (UTC)

If that is the goode one, I'd like to keep clear of the Baad Homolosine. 141.101.105.41 14:08, 6 February 2022 (UTC)

What's the reason for thinking the ships are sailing towards Europe? The prevailing wind in the north Atlantic is more or less westerly, so ships tacking into the wind are more likely to be heading west. 162.158.222.155 20:00, 6 February 2022 (UTC)

They're pointing right, which matches the map? (Was posting the following comment, but might as well answer this straight away.) Also, being chased by a pirate towards all those lovely New World riches seems funny idea, on balance. Although of course it depends on when and how a privateer discovers a possible prize... for some reason in the very middle of the Atlantic rather than in a more bottlenecked part of the trade-routes. Perhaps the merchantman was spotted leaving the vicinity of Bermuda (they have the sails for it!), with signs of carrying cargo of value, and it was considered worth chasing all the way to the mid-Atlantic, just about catching them up. The voice 'from the map' comes from the Easterly ship, as well, so that can really only mean that it went just a little more east prior to the gap-in-the-map appears and it would make Europe the most practical destination afterwards. As for the winds, matching the map position with prevailing/trade-wind diagrams, they could easily be caught in a north-westerly/north-easterly zone that naturally forms a gyre in the atmospheric flow (on average, and of course passing weather systems can send contrary winds any which way off the various edges of a rotating or counter-rotating pressure-system as it moves loosely across the ocean. On the whole I think it was a reasonable assumption to make that they're Europe-bound (by inclination and/or because that's the way the chase takes them), based upon both illustrative convention and the general logistics of the situation, but then with the possible top-mast flags 'error' I'm not sure exactly how strictly Randall intended this all to be. He could have colour-coded the dots, individually, if he was even that bothered - not just made them both red. 172.70.85.79 20:23, 6 February 2022 (UTC)

Very long explanation for nothing ;-) That they are sailing east is clear from the fact that the red dot closest to Europe is the one being chased, and it just crosses the meridian from the west to the east so they can throw the switch. End of all other arguments. ;-) --Kynde (talk) 17:27, 13 February 2022 (UTC)

Westerlies blow from the West to the East. It could be argued they're within the Trade Wind latitudes, but the ships are positioned far enough up North for me to believe they're meant to be in the Westerlies. 172.70.230.157 21:35, 28 February 2022 (UTC)

So by my (less than encyclopedic) reckoning, that's a fast gaff-rigged sloop flying chasing what appears to be a more cumbersome gunter-rigged (or bermuda?) schooner (iffy on that one, but it's not a ketch). What's most strange is that they're triangular, not square, as a merchantman/non-raider should need (especially in a chase such as this) as much sail as possible just to get its deeper and wider hull moving. Neither are using topsails, maybe because the wind conditions are contrary. Yes, the top-flags are pointing backwards, but then that's also a common artist error (with anything other than a modern wingsail), while both ships are flying clearly foreward sails (not spinnakers, I'm sure) and the chased one seems distinctly inflated to the direction of travel. Era-specific peculiarities are beyond my easy assessment (or indeed what century such an encounter might actually be in). 172.70.85.79 20:23, 6 February 2022 (UTC)

I think it is safe to say that Randall did not think too much about how the ships sails worked. For one if the ship has the wind in from the back, then the flags would blow the other way, since the ship will never sail as fast as the wind. --Kynde (talk) 17:30, 13 February 2022 (UTC)

Nah. Randall knows full well how sails and flags work. I reckon he deliberately drew it that way to drive traffic to this site. We should thank him. :-) --172.70.90.121 16:06, 1 March 2022 (UTC)

It should be noted that the Dymaxion map used afloat would almost assuredly be of the "contiguous oceans" variety of projections, not one of the versions that splits the oceans to produce contiguous land masses... 162.158.107.104 16:21, 7 February 2022 (UTC)

Changing the projection would be extremely unhelpful for any other ships traveling the Atlantic between North America and Europe which hadn't arrived at the meridian yet, as they would have to travel hundreds of miles out of their way to continue their journey. Not to mention, any ship that was on the meridian elsewhere in the ocean would be split in half. --172.70.178.25 21:42, 7 February 2022 (UTC)

The strange large anachronistic square incongruous inscribed otherworldly ¿synthetic? reality-warping switch....

Interesting edits about the switch, along the way. Generally I think compounded adjectival descriptors go by the order of opinion, size, age, shape, (existential) quality, colour, origin, material and purpose - though there are disagreements and alternate versions of that list. What is incongruousity? An opinion or a quality (or origin, at a push?), I'd guess, making each order potentially valid. (In advance of any further arguments, I suggest "strange large" rather than an edit-war, though I personally like its incongruousness being mentioned, and incongruousicity in general. YMMV.) 162.158.159.73 17:22, 5 February 2022 (UTC)
