But you can literally sort of do the mathematics of Schrödinger's equation around a carbon atom, and you can make the argument that instead of this cubic structure, there could be a kind of hexagonal structure that is even more stable >> Mhm. >> and even more hard, okay? >> The question is, is that real? >> Right. >> So, 1962, they published this paper in nature and in the 1966-67

It was one of the first sort of science field trips that my family took and I got to see the Meteor Crater in Arizona. It is an awesome awesome place. 50 m is about the size of the meteorite that hit Arizona and it has a bunch of shards that fell all over Arizona and that they've been recovered. >> Mhm. >> Okay?
