Electrons embedded in a cloud of positive charge.<br /><br />Schrodinger's equation - wave equation for energy states of an electron, among other things. The first problem usually solved in a QM class is the problem of an electron trapped in a potential well.<br /><br />Schrodinger's cat - an analogy for the quantum superposition of states - cat in the box may or may not be dead, not known until observed. In my opinion, the dumbest physics analogy ever, but I haven't come up with another one.<br /><br />Einstein: some measurements depend on perspective (relativity)<br /><br />Pauli Exclusion Principle - no two identical fermions (e.g. electrons and protons) can occupy the same state at the same time. <br /><br />Bohr: among his many contributions, defined operators that commute or don't. Commute means that they can be applied in any order and the result is the same. For example, adding 2 to something, then adding 4, is the same as doing it the reverse order. However, adding 2 then dividing by 2 doesn't commute.<br /><br />Hope this helps??<br /><br />E.P.<br /><br />p.s. I went to grad school with a woman from Hamilton, Ohio and we were always asking her for a ride to school. If you get the joke, you shouldn't be reading this - you should be finishing your thesis. You can't mooch off your adviser forever, though many have tried.E. P.https://www.blogger.com/profile/12794103242916034865noreply@blogger.com
