Monthly Meeting November

Music and Astronomy.

We will talk about mathematical and psycho-physical foundations of music; what makes it beautiful — tones, octaves, intervals, consonances, and cords; about types of musical instruments, temperaments, and the art of musical tuning. From this we will draw connection to the “sounds” and harmony of the Cosmos, discuss problems of resonances and stability of planetary systems, motions of moons and geometry of rings. Together we will try to discover the unique “melody” of our Solar system. I’ll use my violin to illustrate my talk.

Our speaker, Sergei Gulyaev, is Professor of Astronomy and Space Science and Director of the Institute for Radio Astronomy and Space Research at Auckland University of Technology.
