Strongly recommended as a mind-bending, approachable explanation of aperiodic patterns, even enjoyable with kids.

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.

“My kids and I geeked out over the Veritasium video on Penrose tiles” (HN, 2023)

on HN thread First nuclear detonation created ‘impossible’ quasicrystals
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]

on HN thread The first atomic bomb created ‘forbidden’ quasicrystal
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]
