Bill, <><><> I read Maxwell when a grad student during the Vietnam War era. I seem to remember after the thirty-five intervening years that then I didn't understand everything, but had sufficient faith that what I was seeing represented div{D}=rho etc. etc. from the then current text books. Incidentally, MKS units were not what Maxwell used. I now am told that Mike Underhill has copies of these books so I'll borrow them off him and have another look for you.<><><> Incidentally, div{D}=rho is actually a first order differential equation in four dependent variables (Dx Dy Dz and rho) and four independent variables (x,y,z,t) although the t is implicit. Etc etc for the other three equations.<><><> Do you really want to bother yourself with all this history? Yes, I know it is fun, but can't you just sit back and watch and listen to all the amazing consequences we have spun out of this dry mathematics, technologically speaking? <><><> All the best,,,,,, David.
