Thank Steven that was excelent. Again I focused on something that confused me.
But thanks to you all of you I am trying to understand it all without trying to rewrite anything...but its not easy for me. I looked into getting a math tutor but gave up on the idea so it is a frustration to have these interests and no tools so to speak. You would have noticed the thread re the trcking in the double slit..that was very interesting.
