4. And another nice thing is when you make a mistake you learn something.

Thanks for the correction and the comments. I learned something.

I doubt it would have been photons that I was learning about all those years ago, though. I recall going to some early lectures on superconducting ceramics many years ago, that could have been it. In any case it was at least 25 years ago when I had that problem when I had to study the sorting of beads into containers, early in the days of combinatorial chemistry.

My son, an excellent undergraduate student in Materials Science Engineering likes to tell me, by the way, why my demonstrations when he was a kid were lousy. He also likes to correct me on the pronunciation of certain terms and names.

I love it.

Thanks again.
