Shechtman’s 10-Fold Symmetry Note: alloy defied crystal rules; quasicrystals reshaped materials science

In 1982, materials scientist Dan Shechtman observed an unusual tenfold symmetry in an aluminum-manganese alloy, defying the established definition of crystals. Despite initial skepticism and resistance from the scientific community, his persistent research led to the discovery of quasicrystals, a new form of atomic ordering. This groundbreaking finding revolutionized crystallography and earned Shechtman the Nobel Prize in Chemistry.
