- pfortuny 7mo agoNot in 3D.

- adrian_b 7mo agoThat image just demonstrates what was mentioned in the article, that the sphere cannot be covered only with regular hexagons, but a part of them must be replaced with regular pentagons, so the angles that are multiples of 30 degrees are not sufficient. So the previous poster was right.
- pfortuny 7mo agoAn angle projected on a plane is not the same as a 3D angle. Also see the structure of diamond (109 degs).
- SAI_Peregrinus 7mo agoNot in 3D Euclidean space. I'm pretty sure 3D Hyperbolic space allows it just fine.
- BigTTYGothGF 7mo agoThe universe seems perfectly happy to have, for example, 5-member rings tho.
- dekhn 7mo agoSee buckyballs as a trivial refutation of your point.
- HappySweeney 7mo agoAre buckyballs organic?
- dekhn 7mo agoYes! Not sure why you're asking- things don't have to be created by biological processes to be organic (this concept is totally unrelated to "organic" in the supermarket).
- andrewflnr 7mo agoFormally, yes. "Organic chemistry" is not too far off a synonym for "chemistry with carbon involved".
- IAmBroom 7mo ago"Not too far off" = "exactly defined as".
- andrewflnr 7mo agoI wasn't sure if there were any weird edge cases, but yeah.
- dekhn 7mo agoI mean, I don't think diamonds are considered "organic"; same for graphite. But that's where the term "organic" itself starts to break down as a category.
- andrewflnr 7mo agoI was also thinking carbonates in a geologic context.
