I checked the Actinides and it looks like the criteria for "fire" is half-life < 1 day. [[User:SpriteGuard|SpriteGuard]] ([[User talk:SpriteGuard|talk]]) 18:11, 21 August 2024 (UTC)
:I would have found it funnier, if only on table-esthetic grounds, if all radioactive elements had been filed as Fire. (I'm a chemist.) [[Special:Contributions/198.41.242.175|198.41.242.175]] 07:58, 22 August 2024 (UTC)

The four classical Elements are still recognised by scientists; They just repurposed the word "element", and so have adopted "state" to describe this older classification - Solid, Liquid, Gas and Plasma exactly map to the classical 'elements'. I think we can forgive the medieval alchemical community for not recognising Bose-Einstein Condensate as their fifth element.

Everyone knows that the 5th element is Leeloo Dallas. Obviously the Bose-Einstein Condensate would have to be the 6th Element.[[Special:Contributions/172.70.111.60|172.70.111.60]] 15:00, 22 August 2024 (UTC)

He's done this comparison between 'classical' and 'modern' elements before... for example in comic #965. [[Special:Contributions/172.70.58.3|172.70.58.3]] 05:52, 22 August 2024 (UTC)

I did what I could for the Fire section earlier, and I've just gone back and added some relevant What-If context for both Mercury and Astatine. The latter is nasty stuff - lucky it can't really exist under standard temperature and pressure, or we'd all be screwed. [[User:Darkwolf218|Darkwolf218]] ([[User talk:Darkwolf218|talk]]) 08:45, 22 August 2024 (UTC)
:The issue of STP doesn't really apply to the whole "fire" grouping, anyway. The thing making them "fire" is not really influenced by changes in temperature and pressure (not unless you're going the way of stellar temperatures and being pressured by an essentially neutronium soup, but we're drifting into many more things being dragged into this, ultimately). The likes of phosphorous is not shown as "fire", when it can be indeed aflame under STP (to not be, you have to ensure the pressure is not from ''our typical mix of'' "air", but one which is quite a bit less reactive), and I'm really not sure (without looking up likely examples) how many of the non-"fire" elements (other than itself, of course) would not effectively set on fire if the pressure requirements was to be provided by a fluorine atmosphere...
:But any concept of "standard temperature, pressure ''and environment''" is obviously beyond the scope of this humorous take. One could even imagine that it be "an infinite space" of the target (nonclassical) element (c.f. "infinite plane" assumptions), without boundary or container, but how that effects the fire/earth boundary of certain radioactive materials (w.r.t. the ability to have a critical density, given a supercritical mass ''without'' being forced together) I think is not necessarily open (or easily obtained) information.

:Phosphorous combines with other elements, like oxygen, to make fire. Radioactive elements produce heat and sometimes higher-frequency light (i.e. "fire") ''all by themselves''. STP with neon as the gas might be a good starting point to think about this, although I wouldn't bet against neon interacting at least a little with some of the more aggressive fire elements.

::To be most sure (given fluorine's actual reactiveness with elements that have more stealth 'shell slots' available to attach to), I'd suggest helium over any other choice. Assuming you [[2766: Helium Reserve|have it]] or [[2972: Helium Synthesis|can get it]], naturally.
::Though, as pointed out, the tendencies of radioactivity really aren't subject to temperature or (short of metals being compressed to super-criticality in nuclear-weapons, which isn't really the same thing) pressure in any way. These do dictate the precise memberships of the non-Fire elements (you can freeze mercury or melt sodium or condense nitrogen, etc), but talking of STP isn't really so necessary in the context of the 'firey fringes', assuming it's based upon arbitrarily-timed half-life-length.

I feel like Munroe just discovered the Aristotle Version of [https://tomlehrersongs.com/the-elements Tom Lehrer's song The Elements] {{unsigned ip|172.70.80.229|16:52, 4 September 2024 }}

172.68.35.59: /* Delaware/Pennsylvania Arc */

==Delaware/Pennsylvania Arc==
The Delaware/Pennsylvania arc is a circle, sure, but so is every other allegedly "straight" line on the map. The 49N parallel looks like a straight line on some projections, but a polar projection shows that it is clearly a circle around a point on the Earth's axis. The Delaware/Pennsylvania arc is only unique for NOT being aligned with the axis. [[Special:Contributions/172.71.102.20|172.71.102.20]] 19:07, 13 September 2024 (UTC)
:The "Delaware/Pennsylvania arc" has a long and juicy history. Not a circle. [https://en.wikipedia.org/wiki/Twelve-Mile_Circle Twelve-Mile Circle] Signed- --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 20:36, 13 September 2024 (UTC)
:True about map projections, but the Venn section title here does say *Weird*. The Delaware/Pennsylvania arc is indeed "weird"; few other such arcs are found in regular map content, and the original story for it is indeed uncommon. <s>Great Circle</s> Parallel latitude "arcs" aren't weird in either way.

::North-South lines are great-circle arcs, but non-equatorial East-West lines - as well as many diagonal ones - are minor-circle arcs (is that the right term?), just link the 12-Mile Circle.

This may be inspired Joël Lapointe's very recently announced discovery of a 15km-diameter "pit" he found near Marsal Lake (Quebec) using Google Maps.
