| Also, remember if the commutator of two operators is nonzero that their eigenstates do not share the same basis. | Also, remember if the commutator of two operators is nonzero that their eigenstates do not share the same basis. | ||

| + | What you said is mainly correct, but remember knowing Lx with more certainty means you know (Lz + Ly) with less certainty, not so much each one indiviually. | ||

| I agree with you, Andromeda, about the notation. It's going to take some getting used to. The concepts and the general ideas are all fairly simple and logical, it's just translating what the notation is saying or taking what you want to do and translating it into the notation to begin solving a problem that's difficult. I don't know about the exam. I'm guessing we'll be told today in lecture what it'll cover and when it'll be. | I agree with you, Andromeda, about the notation.

| + | The notation is a little tricky to learn but I've found that if anything looks simple and the notation is screwing you up then the easiest thing to do is refer back to chapter 3 and see if there is a simple one or two sentence that describes what you're looking for. Today in lecture Yuichi said the test will be on the 11th. | ||

| + | I found that writing all the different notation out with what it means, kinda like making an equation sheet, helps cement it into my brain. | ||
| + | ===Devlin=== | ||
| + | I still find myself moving slowly because of the new notation as well. I think it'll just take practice. | ||
