> If quantum mechanics makes Newtonian mechanics (NM) "obsolete", then what does that imply for Special relativity (SR)? Ah. That's unsatisfying :) It would be super satisfying to have one coherent theory of everything. [1] Why hasn't anybody thought of that before? ;) [1]: And then, again, it is of course useful to have efficient ways to work within subsets of the grand theory, such as NM.
