Bob,
I think this is a pretty cool link! I started reading, got halfway through part #2, then decided to print the whole thing so I could read & hopefully absorb it a bit later.
Re-visiting Physics equations after 30+ years is an interesting experience, and I only wish some of my old Professors had used the car as a basis for some of their lectures- which most of us slept through!
Thanks fo this,
John Russell
