Bismuth crystals don't form like that in nature. All of those are man-made.
But pyrite does
Salt crystals are cubic.
But do they form like cubes in nature like pyrite does?
Wombat poop is cube shaped.
…it's, like, an hour before I've got to head to bed; you can't be giving me rabbit-holes to head down.
What science teacher would say that?
Lol had a grade 4 teacher tell me once that circles aren't natural and an invention of man kind. I figure she must have been a werewolf or something. Never actually seen a full moon or doesn't remember seeing it.
The moon isn't perfectly round, also if it were it would be a sphere not a circle.
Found another werewolf.
Found someone who didn't finish high school.
The moon is round enough that a lot of circle based math works on it
That just depends on what your tolerance for error is. For a lot of purposes your head is round enough that assuming it's perfectly round still works out to be accurate enough. Doesn't make it round.
it was explained in an anime called Ruri Rocks.
it cristalizes into a cube as it cools. that's normal, but the cristalisation is exothermic. this makes the areas in the middle of the faces hotter than the edges, so it cannot cristalize in the centre of the faces and only on the cube edges.
it's explained better in that anime.
Yeah, I think it’s probally art teachers that would have more of a use for such a statement.
watch Ruri Rocks.
they explain why they form like that.
great anime
