q1 - What is the quantum mechanical interpretation of the expansion coefficients of the wave function in an eigenbasis?

q2 - What is a complete set of commuting observables?

q3 - Which of the following are true?

In the Dirac notation, bras and kets are exactly the same.

All observables that don't commute with H are constants of motion.

In quantum mechanics, two back to back measurements of the same quantity never give the same result.

None of the above.

Below is a space for your thoughts, including general comments about today's assignment (what seemed impossible, what reading didn't make sense, what we should spend class time on, what was "cool", etc.): (If you don't mind, please include your e-mail address for quick replies from Prof. Kim-Shapiro - this is optional)
