Quasicrystals and Symmetries

Quasi crystals are a new form of matter that challenge traditional symmetry rules in solids. Unlike regular crystals, which have repeating atomic patterns, quasi crystals exhibit forbidden symmetries and repeat at irrational frequencies. This unique structure is analogous to disharmonic sound, which appears noisy but is actually ordered. The video explains the differences between random, crystal, and quasi crystal arrangements, highlighting the complexity and unpredictability of quasi crystal patterns.
