Dear Tom
Thanks for your very interesting note. Of course at the most basic level everything is related, and more specifically we may think of the physics - i.e. acoustics - of music and even of the musicality of some concepts in physics such as the vibrating strings of String theory. Herschel was a professional musician before turning to astronomy. Further back in time there is Newton's correlating colors with notes and Pythagorus' concepts of number, musical scale and the music of the spheres.
Your own work on Structural Resonance sounds most interesting and I hope to study more about it in detail when you publish the material. Resonance of course is the basis of the first electronic musical instrument invented by Léon Theremin .
Einstein was a gifted violinist (but that does not make him a string theorist). Your quoting his letter to Besso where he wonders if his physics would be meaningful if fields are not continuous is most relevant in the context of this contest. His core discovery in general relativity that gravity and acceleration are one would still be a key result in a digital universe, his protest to the contrary notwithstanding. I have tried to show in my in my earlier 2005 Beautiful Universe paper on which my present fqxi paper is based that GR would be greatly simplified in a digital universe, reduced to the 'optics' of refraction in a medium of variable density.
Best wishes for success in your music and physics! Vladimir
