In the 6th century BC, Pythagoras developed the science of harmonics. Legend has it that he was inspired by the sounds emanating from a blacksmith’s shop; producing experimental music with hammers and anvils, Pythagoras realized that the relationship between different musical notes can be expressed in the form of simple mathematical ratios.
Pythagoras saw in this a fundamental theory of the universe, and redefined the world – from the motion of celestial bodies to the emotional fluctuations in a human body – as iterations of a kind of cosmic music. More than a millennium later, Johannes Kepler interpreted this musica universalis as proof of Divine splendor, and devoted his career to a description of the geometric and harmonic order of our solar system.
Efforts to chart this celestial harmony can produce strikingly aesthetic images. Kepler’s sketches proved as much in his publications – as does this work by software developer Howard Arrington. Arrington used his own Ensign software to visualize the relationship between pairs of planets, producing a series of intriguing geometric mosaics. Better yet, he shares the program with which he created his images, so that you, too, can capture the music of the cosmos.
