Lecture #24.

I watched most of the new material parts of lecture #24 now. I suspect we will get to the end of the course by the time of the break in lecture #24. I hope I can get to the break by 6PM tonight. Then I will spend a few hours until about 9 PM with both exam review sections on lecture tapes #12 and #24. I just took about an hour break to talk with my dad and eat some food.
