Can't see the other side- if it's a 2 dimensional representation of a 3 dimensional object in can still be accurate because of perspective.

[-] Blackout@fedia.io 65 points 1 month ago

There's a third dimension now?

[-] NounsAndWords@lemmy.world 47 points 1 month ago

Not really, but it's a useful assumption for lots of different types of maths.

[-] JackFrostNCola@lemmy.world 4 points 1 month ago

As long as everything you imagine in 3D space is spherical

[-] Klear@lemmy.world 3 points 1 month ago* (last edited 1 month ago)

Quaternions make a whole lot more sense when you imagine a third spatial axis and use them to rotate a hypothetical 3D object.

[-] nichtburningturtle@feddit.org 2 points 1 month ago

This is madness!!!

[-] quinceyBones@lemmy.zip 29 points 1 month ago* (last edited 1 month ago)

Yes, time is the third dimension.

[-] nightwatch_admin@feddit.nl 8 points 1 month ago

Always has been

[-] ZoopZeZoop@lemmy.world 2 points 1 month ago

Yes, and now some bozos are even discussing a 4th dimension. Something to do with chess, I think.

[-] KazuchijouNo@lemy.lol 32 points 1 month ago

My thoughts precisely, they are just assumimg this is just a 2D circle, when in reality it's more likely to be a 3D sphere. They aren't accounting for the area of a 3D object, we don't even know the thickness of the "slices" that are flying.

Sphere vs circle

[-] davidgro@lemmy.world 95 points 1 month ago

Generally explosions do in fact involve an object suddenly increasing in volume (with corresponding decrease in density)

Said objects typically become partially gaseous, but if the rest of it is porous then it's not unusual at all for that to increase in volume also.

Easy example: popcorn.

[-] CeruleanRuin@lemmings.world 37 points 1 month ago

Neither does popcorn.

[-] Rivalarrival@lemmy.today 33 points 1 month ago

Why assume it started off as a sphere? Everything makes sense if it started off as an irregular blob.

[-] fallingcats@discuss.tchncs.de 30 points 1 month ago

It might well have started our as a sphere. But you also need to rotate pieces in the third dimension of you want to pay the sphere back together.

[-] mindbleach@sh.itjust.works 28 points 1 month ago

Sphere looks like circle. Chop sphere in half, lay flat, looks like two circles. BOOM, Banach-Tarski!

[-] apotheotic@beehaw.org 28 points 1 month ago

I mean, its representing a 3 dimensional object, so a lot of those "areas" are actually volumes which can stack "behind" one another

[-] Th4tGuyII@fedia.io 26 points 1 month ago

Only if you assume the object was round. I mean it was almost certainly meant to be round, but it could be right ¯\_(ツ)_/¯

[-] frank@sopuli.xyz 10 points 1 month ago

If it was round it wouldn't have blown up!

[-] ArtieShaw@fedia.io 3 points 1 month ago

Right? Round isn't what I'd think to call "a funny shape." Maybe some folks do though.

[-] MeowZedong@lemmygrad.ml 2 points 1 month ago

I presume it was a round-bottom flask as explosions are usually the fault of chemists.

[-] harcesz@szmer.info 21 points 1 month ago

Do you people hate the SAUCE? What sort of savagery is this?

[-] PapaStevesy@lemmy.world 11 points 1 month ago

Sure it does, it's just not round.

Clearly the artist believes in the axiom of choice

[-] mihor@lemmy.ml 8 points 1 month ago

On a similar note, I don't know which doofus created the cancerogenic warning symbol. It's so stupid that I didn't understand it when I first saw it and thought it meant that it irritates breathing or something. Truly stupid.

[-] psud@aussie.zone 2 points 1 month ago* (last edited 1 month ago)

Could you link to the symbol? It's not on the Wikipedia list of hazard symbols

It's the middle bottom one here, isn't it

[-] mihor@lemmy.ml 1 points 1 month ago

Yes, it's the middle bottom one. Looks like a guy's chest is exploding for some reason. 🙃

[-] smuuthbrane@sh.itjust.works 7 points 1 month ago

It just means the explosion had so much energy some of it was converted to mass. As you cannot determine what kind of explosion that is, this explanation cannot be disproven in general terms.

That symbol must be very triggering for Superman

[-] And009@reddthat.com 4 points 1 month ago

Assumed it's a shitpost. But it isn't!! This is serious.

[-] thedarkfly@feddit.nl 4 points 1 month ago

I wonder who's the artist behind the symbol

[-] leftzero@lemmynsfw.com 3 points 1 month ago
[-] black_mouflon@beehaw.org 2 points 1 month ago

Conservation of area is not a law of nature.

[-] user1234@lemmynsfw.com 1 points 1 month ago

Looks almost like a human heart.
