 As far as I can tell, determinate states are just eigenfunctions of certain operators.  For example, the stationary states we've been studying are determinate states of the Hamiltonian.  For the stationary states, every measurement of the particle in a stationary state gives a corresponding energy.  It really is just eigenfunctions and eigenvalues. As far as I can tell, determinate states are just eigenfunctions of certain operators.  For example, the stationary states we've been studying are determinate states of the Hamiltonian.  For the stationary states, every measurement of the particle in a stationary state gives a corresponding energy.  It really is just eigenfunctions and eigenvalues.

 +I think indeterminacy is the phenomenon in QM when you have a bunch of identical systems all in the same state and you don't get the same result each time you measure the observable. So a determinate state is the idea that you could prepare some state where you get the same value for every measurement of the system (Griffith calls it 'Q'). Its in a state that is 'determinate'.

 The test was fairly straightforward. After the first test, I made a more concentrated effort at studying for this one and it seems to have paid off.  The test was fairly straightforward.

 +I'm not quite sure I've got all correct answers for the test but it was reasonable length and also appropriate amount of time.
