Hi, There is one question that couldn't answer when studying physics (or found in any text): Where originally did Classical Mechanics went wrong? QM texts just go straight into the details and nuts and bolts of QM without touching this question, and general physics texts do talk about phenomena such as interference, light particle/wave duality, etc... without actually stating a phenomenon showing the discrepancies between calculations done by CM, QM and empirical data. It could be that I haven't read all the books carefully enough or haven't read the right sort of thing... so if anyone can clarify this for me that would be incredible. :!!) And similarly, what is the problem between QM/Rel and putting the two together? Thanks!
