Sorry it's been 6th months since the last one of these. I've been a little swamped with school. Good news is, it's full steam ahead, now ( Read more... )

Here's the continuation of the last post, where we look at the problem I mentioned and see where it leads. (90% of this material is stolen from Griffiths E&M book. I blame Asma.)

So, I know I still haven't finished the second half of that earlier physics post, where we'll derive the Schrodinger equation from classical mechanics, but I thought I would take a little detour first. There was a problem that's been bugging me since the middle of last semester. I asked Asma about it the other night, and she gave me some very nice ( Read more... )
