What a discussion ... I sorta wish that I'd looked into this thread earlier, but then would really have started goofing off too much at work. That delightful piece on harmonies made for fun reading.
While you guys are somewhere remotely close to the topic, what's your take on Lewis Little's Theory of Elemental Waves? It slipped under my casual physics radar back in 1996, and I still can't remember how I stumbled across it.
