There's also one for a .gz file of some source format (probably LaTeX with some physics macro package(s)), but I couldn't get either one to work (got "408 Forbidden"). I assumed then that perhaps it wouldn't be available until after peer review or perhaps one had to have a loginid and password to give the web server first. > >But my Quantum-Mechanics course 10 years ago was obviously not enough >for me to be able to follow that paper. ;-) > I never had a full course, just maybe two-thirds of a semester in a survey course probably more like 20 years ago. Too bad, though, because it seemed pretty cool at the time. :-( But from the abstract, it kind of looks like a good understanding of quantum physics might not be enough. A course in general relativity, which isn't even offered in a lot of universities these days, might also be necessary. Anyway, it seemed like they came up with a nifty idea, though it fortunately remains one for science fiction (for now). Scott Bennett, Comm.
