Five fold symmetry meaning
WebJun 28, 2024 · Still, five-fold symmetry in crystals was still a fringe idea when Shechtman published his paper. The paper triggered a frantic race for other chemists to produce and observe the same type of structure. Some were successful and praised Shechtman, naming the structure “quasicrystals” and publishing several papers. But others were less thrilled.
