The commutation from hell

< Si,Sj > = i eijk h/(2pi) Sk

(Those should be square brackets, but I can't get them to come out right)

who'da thunk it?
:shrug:

what's purple and commutes?

So... My quantum prof was quite a wit, and there is a truely pricessless story from the year before I had him, when one of my friends, also with a razor sharp wit was in his class:

It's the week before easter, and things had been moving pretty smootly and he was ahead of schedule. It was friday and rather than start in on the new material about the Born Approximation, he decided to finish up early. So he announced to the class his decision that since it's friday, he's going to finish class early today.

My friend replied that in light of this decision it was in fact a "good friday".

The professor one upped him by responding that he had decided that it was in the best intrest of continuity to "pass over" some material for later.

To which my friend agreed replying that it was probably in the classes best interest to "kill the first Born approximation"...

;)

doesn't take long to hear em all...
