Abstract
Three properties of quasicrystals will be proved in this essay. Quasicrystals are almost periodic patterns (such patterns are carefully defined below). Every mean-periodic function whose spectrum is contained in a quasicrystal is almost periodic. Finally simple quasicrystals are universal sampling sets.
