Don't I have any chemists reading Building Batman? No? No chemists training to become Batman? Oh, well...
I was thinking about the Final Fermi Problem and it occurs to me that I made a bad estimate:
I said that each carbon is bound to 8 others because of the crystal structure. That's not true.
Carbon is tetravalent which means it will always have the equivalent of 4 four bounds, no matter the crystal structure.
Now you and I know that when estimating that factor of two isn't a big deal but I thought I'd better tell you in case you're you're doing this last Fermi question or in case a chemist stumbles past Building Batman.
PS If you are a chemist, you might get a kick out of this periodic table
