Monday Night Philosophy understands thoroughly that music matters. Pythagoras (whom we all know from basic geometry) thought so, too – he is well known for having uncovered the mathematical ratios underlying musical harmonies. He was so taken with his discovery that he proclaimed “all is number,” and that there is a divine harmony, a music of the spheres, caused by the planets racing around a central fire in perfectly circular orbits. This first idea led directly to the development of the lush harmonies that came to define European classical music. The second, while partially obfuscating the realities of our solar system, nevertheless inspired Ptolemy, Copernicus and Newton in their search for the physical truth of our universe. Join us for a conversation of where the excitement with sound all began.
