One of the three sections into which the French astronomer Nicolas Louis de Lacaille divided the oversized Greek constellation of Argo Navis, the Argonauts’ ship, in his southern star catalogue of 1756. In that preliminary catalogue he gave it the French name Voilure du Navire, which was Latinized to Vela in his final catalogue, Coelum australe stelliferum of 1763.
- Platonic solid (Wikipedia)
In geometry, a Platonic solid is a convex, regular polyhedron in three-dimensional Euclidean space. Being a regular polyhedron means that the faces are congruent (identical in shape and size) regular polygons (all angles congruent and all edges congruent), and the same number of faces meet at each vertex.
