The good, of course, is always beautiful, and the beautiful never lacks proportion.” —Plato
Plato’s words continue to echo truth to this day. Architects, for example, must carefully map out their creations in an orderly fashion. While there are endless ways to do that, ancient architects knew of a hidden code: the Golden Ratio, also called the Golden Mean or the Divine Proportion, and related to the Golden Rectangle, the Golden Triangle, and other, similar terms.
