This thread might be a tad old, but I'm just adding my two cents for anyone that is still interested. Generically speaking, there are 2 independent notions that can be defined on a (Riemann-Cartan) manifold: 1) The metric, for determining infinitesimal lengths 2) The connection, for...

An observation interferes with the current state of the electron. If the electron is in some (initially superimposed) state, then performing a measurement will "throw" it into one of the constituent Eigenstates. This is what "destroys" or changes the behaviour of the electron as it passes...

Well, if you take a Hydrogen atom, isolated from everything else (in terms of interaction) and then measure the electron's energy, it will be in an energy eigenstate after the measurement.

I have not seen this book you speak of, just went through the contents on Amazon's free preview. Based purely on that, the approach in Sakurai (Modern QM) seems to be kind of similar. If you want a start, you can look through Sakurai's book. It has one section on the Density matrix (3...
