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.

There's a third dimension now?

[–] [email protected] 47 points 3 weeks ago (2 children)

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

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

[–] [email protected] 3 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

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

[–] [email protected] 2 points 3 weeks ago

This is madness!!!

[–] quinceyBones 29 points 3 weeks ago* (last edited 3 weeks ago)

Yes, time is the third dimension.

[–] [email protected] 8 points 3 weeks ago

Always has been

[–] [email protected] 2 points 3 weeks ago

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

[–] [email protected] 32 points 3 weeks 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

[–] [email protected] 94 points 3 weeks 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.

[–] [email protected] 37 points 3 weeks ago

Neither does popcorn.

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

[–] [email protected] 30 points 3 weeks 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.

[–] [email protected] 28 points 3 weeks ago

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

[–] [email protected] 27 points 3 weeks ago

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

[–] [email protected] 26 points 3 weeks ago (2 children)

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

[–] [email protected] 10 points 3 weeks ago (1 children)

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

[–] [email protected] 3 points 3 weeks ago

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

[–] [email protected] 2 points 3 weeks ago

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

[–] [email protected] 21 points 3 weeks ago

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

Clearly the artist believes in the axiom of choice

[–] [email protected] 11 points 3 weeks ago

Sure it does, it's just not round.

[–] [email protected] 8 points 3 weeks ago (1 children)

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.

[–] [email protected] 2 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

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

[–] [email protected] 1 points 2 weeks ago

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

[–] [email protected] 7 points 3 weeks 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

[–] [email protected] 4 points 3 weeks ago

I wonder who's the artist behind the symbol

[–] [email protected] 3 points 3 weeks ago

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

Conservation of area is not a law of nature.

[–] [email protected] 1 points 3 weeks ago

Looks almost like a human heart.
