RayRaz, Glad you got through it ok. math is really important - The thing that griped me when I was learning it is that nobody ever told me what all that trig and calculus was for except for Dr Brown and he couldn't make up for the years of neglect by teachers that should have been teaching 'how to be boring' rather than math. I had to learn programming inorder to see that it all had a purpose - especially in graphics! You'll like that site - it talks about exactly the type of things you're asking about. I used to be able to do that type of stuff until I got shot, got an anesthesia I was allergic to, and my math skills went to zero (I guess it killed a few brain cells or something.) One thing you will find is the unified field equation hasn't been completely solved yet - maybe you'll be the one to do it! BTW: Dr. Michio Kaku will be on the Art Bell/George Noory program sometime this week. I think Tuesday Morning for you if you can find a station that carries it. cheers, - TJ
