You should buy the book and read it for yourself. My explanations of what I think I
am reading are naturally going to be less effective then getting the information

you would enjoy reading.

Yea, I suppose they do that as well.

Grin... Math yes... I keep telling myself I am going back to school.  Its just
right up the hill from where I live...  5 minutes walk.... Math would be a cool
