The [[Golden Ratio]] also is called the golden mean or golden section. Other names include extreme and mean ratio, medial section, divine proportion, divine section , golden proportion, golden cut, and golden number.<ref>[http://en.wikipedia.org/wiki/Golden_ratio]</ref> | The [[Golden Ratio]] also is called the golden mean or golden section.

[[Plato]] (427–347 BC), in his Timaeus, describes five possible regular solids (the [[Platonic Solids]]: the tetrahedron, cube, octahedron, dodecahedron, and icosahedron), some of which are related to the [[Golden Ratio]].<ref>[https://en.wikipedia.org/wiki/Golden_ratio Golden Ratio]</ref> | |||
The term "[[Phi]]" was coined by American mathematician Mark Barr in the 1900s. Phi has continued to appear in mathematics and physics, including the 1970s Penrose Tiles, which allowed surfaces to be tiled in five-fold symmetry. In the 1980s, phi appeared in quasi crystals, a then-newly discovered form of matter. | The term "[[Phi]]" was coined by American mathematician Mark Barr in the 1900s.
