Make sure you include a theoretical physicist in your discussion. That way when you finally get tired of it he will explain that until they (physicists) find a way to resolve relativity and quantumn mechanics, this discussion is pointless. LOL! (I once had this discussion with a group comprised of 3 engineers, 2 physicist (one theoretical the other bio,) 1 anthropologist, 1 industrial psychologist and a psychiatrist. If it hadn't been for the theoretical physicist I think we would still be sitting there, actually standing there, discussing the issue. Of course, I find that theoretical physicists try to claim that membrane theory (the current way of resolving the two) must be understood in order to deal with any problem.)

Happy New Year!
