I've put quick intros to these subjects on my web site, and I'd like to invite readers to comment. The goal of the tutorials is to give as quick an introduction as possible with the miminum of unnecessary technicalities, and yet to get to the essence of the matter . No doubt improvment is possible. Maxwell's Equations www.berkeleyscience.com/maxwells.htm What's unusual - I was always a little buffaloed by the curl and gradient operators, and I set out to give the reader a feel for these operators. I discovered I could present the essence of Maxwell's equations without using them at all, and I'm happy with the result. Special relativity www.berkeleyscience.com/relativity.htm What's unusual - the derivation of the Lorentz transform is by experiment and not algebra. There is also a very quick proof of e=mcc. General relativity www.berkeleyscience.com/gr.htm What's unusual - this you have to see to believe - no use of Einstein's notation so everything is written out - plus there is a special 2-d pedagogical solution to the field equations.
