    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.

      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

    3. @MontagFTBMar 2023· in “Mathematicians discover shape that can tile a wall and never repeat”

      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.

      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
