Description
In 1885, the Russian crystallographer Evgraf Stepanovich Fedorov was studying the molecular structure of crystals, when he discovered that there are only five families of polyhedrons (cube, truncated octahedron, rhombic dodecahedron, hexagonal prism and elongated rhombic dodecahedron) able to pave space, using translations only.
In 2012, the Japanese mathematician Jin Akiyama demonstrated that it is possible to create an element of each of these five families by joining Pentadra (irregular pentahedrons). A Pentadron cannot be divided into equal polyhedrons. It is a mathematical atom.
