“There is geometry in the humming of the strings, there is music in the spacing of the spheres.”
Pythagoras is known for the Pythagorean theorem, Pythagorean tuning, the five regular solids,
the Theory of Proportions, the sphericity of the Earth, Music of the spheres (the idea that the movements
of celestial bodies—the Sun, Moon, and planets—are a form of music) and the identity of the morning
and evening stars as the planet Venus.
