Thanks for those links to those Mark Ioffe pages, that was actually close to what I was looking for when I found your site. I'll have to read over them when I can.
Hmm, I'd never thought about the time-varying difference between [d R(t) / dt] and [~w] for constant angular velocities. But what you say would be right [~w] would be constant and [d R(t) / dt] would still vary if R(t) changes...
