Yale-Led Team Solves Half-Century Carbon-Crystal Mystery
slew writes "Unlike its more famous carbon cousins: diamonds and fullerenes, you've probably never heard of M-Carbon, but this form of compressed graphite which is as hard as diamonds has baffled researcher for half a century. Over the past few years, many theoretical computations have suggested at least a dozen different crystal structures for this phase of carbon, but new experiments showed that only one crystal structure fits the data: M-carbon."
Nice of TFS to not link to anything describing M-carbon.
Maybe this will help. Maybe it was "common knowledge", but I personally hadn't heard of the stuff till now.
How is the Riemann zeta function like Trump rallies? Both have an endless number of trivial zeros.
Though he has been baffled, his name has not been released.
