Naturally Occurring Quasicrystals

It's a riveting account of years of research to discover Quasicrytals from theory, to experiments, to literally hunting in a meteor field in eastern Russia!

- Nzen - 9435 sekunder sedantl;dr Quasicrystals are aperiodic structures. The author notes that the conditions for creating them are rare, given the need for instantaneous high temperature. They recount that these can happen during space debris impact and when lightning hits sand. They close out by describing some of the chemical 'formulas' for these materials, given that characterizing a prototypical section is difficult without repeating elements.
I don't have anything to say about quasicrystals, other than it seems right up this blog's alley, as the other most recent articles are about math and materials (like feldspars [0]).
