What does Pythagoras have to do with the moon?


This year marks the 50th Anniversary of the Apollo 11 moon landing. To commemorate this remarkable technological achievement, the Australian National University is currently hosting a series of lectures exploring the moon through the ages (Works that Shaped the World: ANU Discovery Series 2019).

I was recently invited to present a lecture in the series. I chose to speak about the mysterious Greek philosopher Pythagoras and his theory of the music of the spheres, that is, the theory that each planet and heavenly body emits a sound as it travels through space and that these sounds combine to produce harmonious music.

What would Pythagoras have made of the moon landing? What would he think about his name being ascribed to an impact crater on the north-western rim of the Moon? What would he make of our efforts to hear the ‘sounds’ of planets or to transmit music into space?

Join me for a voyage of discovery, starting in the sixth century BC and ending in the present day, exploring the life and ideas of Pythagoras: a truly remarkable, multidisciplinary and unconventional thinker:
