Great video thanks for sharing. My brain still hurting, it tried to explode at 14.38 :-) [VIDEO] Also quite interesting these are found in a few meteorites. I wonder if somebody is confidentially keeping some quasicrystal with very special properties somewhere. "Third-ever natural quasicrystal found in Siberian meteorite" [LINK]

My kids and I geeked out over the Veritasium video on Penrose tiles ( [VIDEO] ). It is pretty exciting to see approachable math like this being discovered before our eyes.
