Oops it was only 10+ years ago the first French experiment was conducted.

I'm not a friend to Bohr.
As I have said before I'm an Einstien guy and favor an elegant universe. If superstrings exist it makes sense to me that the smallest possible particle is a wave and is an active part of a vibrating universe.

If you ever make an oil drop experiment in your kitchen, B flat 3 octaves above high C works well. btw B flat is the background pitch for the entire universe. Its just deeper than one can an imagine, or hear.

I used an underwater speaker but it doesn't matter. What does matter is a perfectly level fluid table.
