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.

Why HN likes it: 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”
