Between chemistry classes, gemstones, and electronics, the idea of crystals, that is, substances with an ordered and periodic arrangement of atoms is quite common. But about 40 years ago, a strange particle was discovered by scientists that hasn’t become commonplace in our world yet: quasicrystals. These are structures with curious atomic arrangements, which, while superficially similar to crystals, lack periodicity despite being ordered. Because of their structures, quasicrystals exhibit symmetries forbidden to crystals and are endowed with interesting properties that crystals cannot show, such as high resistance to heat flow, current flow, and corrosion.
