Uppsättning 14 Bravais-gallerier

Set of easy to handle models of the 14 fundamental lattice types (Bravais lattices), from which Auguste Bravais postulated that practically all naturally occurring crystal lattices can be derived by shifting along the axes. Made of wooden balls in six different colours connected via metal rods. The six colours distinguish the six different systems into which […]
