Veritasium explains how Penrose tilings and quasicrystals overturned the belief that 5-fold symmetry and non-periodic crystals were impossible, including an interview with Paul Steinhardt.
Strongly recommended as a mind-bending, approachable explanation of aperiodic patterns, even enjoyable with kids.

My kids and I geeked out over the Veritasium video on Penrose tiles ( ▶ this video ). It is pretty exciting to see approachable math like this being discovered before our eyes.
Great video thanks for sharing. My brain still hurting, it tried to explode at 14.38 :-) ▶ this 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
The Youtube channel "Veritasium" featured a great video on Penrose tilings and their relationship to quasicrystals [0]. A fascinating example of a mathematical discovery with a previously unsuspected physical incarnation. [0] ▶ this video
I just happened to come across this fascinating video[0] yesterday that explained the same thing. And he mentioned the crystal as well. [0] The Infinite Pattern That Never Repeats: ▶ this video
