When particles get zinging around near c in, say, the Bevatron here at Berkeley, not only does it require more energy to accelerate them, but when they smash into something (i.e. an antiparticle or something like that) the energy released is significantly *more* than can be acounted for by the particles rest mass (by a factor of several hundred if I remember correctly). I doubt Mr. Ritz accounted for that. After all, his time was long before particle accelerators. -- Another student, lost in the sea that is called Bezerekely. His name? E.
