## From Beautiful Tilings to Improbable Crystals

“There are no quasicrystals only quasi-scientists.” Linus Pauling the two time Noble Laureate. So, what are these quasicrystals, who discovered them and why did Linus Pauling disagree with their existence. We shall begin to answer these questions. The crystallographic restriction theorem: A 3 Dimensional Lattice (crystal) can only have 1, 2, 3, 4, or 6-foldContinue reading “From Beautiful Tilings to Improbable Crystals”
