Eighth lecture advanced quantum mechanics
is one of few lectures in the course where calculational flow is being combined with flow of physics: the number of variuos situations we address is significantly bigger than in most of the lectures. There are also pictures. The material is such that a good presentation seems easy. There was a little time problem before the break and in the end of the lecture, I could use several more minutes. The overal timing was however OK. More serious problem is that I am still missing rhythm of the lecture: some pieces I give too slow and some too fast. There were aslo two many blackboard drawings, many of them were extremporized. They could have been at the sheets.
I think the audience appreciated an effort I made, the attention was not lower than for other lectures. There were quite some questions, they’ve also caught me with the hbar coefficients (no, I do not intentionally put incorrect coefficients in intermediate calculations. To confess, somethimes I intentionally do not correct then: proven to sharpen student’s attention). I’ve made a dramatic statement in the end (though did not have much time for that) to prepare the audience for the coherent state: topic of the next lecture.
