Space mirrors have been in the news lately. [[Special:Contributions/2603:8081:9700:1224:0:0:0:3|2603:8081:9700:1224:0:0:0:3]] 03:50, 28 March 2026 (UTC)

As explained in https://what-if.xkcd.com/58/ this wouldn't work anyway since the banner would be moving at 7.8 km/s, or else it would need to be hung from a space-elevator-like counterweight located beyond GSO. If cueball accomplishes THAT kind of feat, I think the astronomers would be more impressed than annoyed.

curses, im too early on the scene for an explanation of what he's gonna do with the items in the titletext; such are the woes of being one of the people writing the explanations that you have to actually ''understand'' the comics - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 02:15, 24 January 2026 (UTC)

If you're otherwise creating fire hazards, a lithium ion battery is a terrible thing to have, and none of the horror stories you've heard involved a sack of them. Flour is a serious explosion hazard. Vinegar and bleach will release chlorine gas when combined. It sounds like an attempt to have the highest ratio of destruction to materials cost with the least effort.

The title text just sounds like a bunch of flammable/noxious substances. So really, he has good intentions. [[User:Tanner07|Tanner07]] ([[User talk:Tanner07|talk]]) 03:57, 24 January 2026 (UTC)

Talk:3189: Conic Sections

Isn't the base of a cone, just a circle? How would this have "corners"? [[User:SDSpivey|SDSpivey]] ([[User talk:SDSpivey|talk]]) 01:41, 3 January 2026 (UTC)
:The cone upon which a conic section exists doesn't actually ''have'' a base, it's just arbitrarily large (possibly infinitely so) in order for the section to only ever lay along the 'curve' of the cone part.
:But, here, the base is wwhere you give up on plotting how far 'down the cone' you go, of the sufficiently large ellipse (or possibly parabolic/hyperbolic curve), which is indeed round but has an sharp (i.e. acute) angle between its flat (and incidentally circular) plane-section and the 'wrapped' pseudo-euclidean plane of the conic-section it intersects with.

I'm pretty sure this is the shape of the flat bottom of a cake cone. [[Special:Contributions/71.212.56.254|71.212.56.254]] 03:02, 3 January 2026 (UTC)

It appears to be a cut-off section of an ellipse, so basically a regular orbit with a sharp line. ([https://www.desmos.com/3d/xnaihdegst Desmos]) [[User:Tanner07|Tanner07]] ([[User talk:Tanner07|talk]]) 04:29, 3 January 2026 (UTC)
