Quasicrystals: Sections of Hyperspace

Since the moment Dan Shechtman discovered a material with an ordered but aperiodic (“quasiperiodic”) structure, which was believed to be impossible at the time, he began a long battle to convince his colleagues that his data were real. His efforts were finally rewarded with a Nobel Prize. The picture shows the projected electron density distribution function of decagonal Al-Co-Ni with Penrose tiling as an example of a quasicrystal.
