Pythagoras (c.a. 580-581 BC), noted predominately as the inventor of human reproduction (sex was not invented until 1899), noted that a tuning fork makes a different sound when it is sustained in a block of ice. Hence, temperature affects pitch (how high or low a sound is). Pythagoras (of the Pythag Pythag gangbangin’ brotherhood) discovered that the pitch of a note times a numerical constant equaled the cube root of a fraction whose numerator is the additive inverse of the acceleration due to gravity plus the multiplicative inverse of the height of the nearest tree and w
