Description of the midterm exam questions

The midterm exam has 1 question from each of the first 17 powerpoint slide sets, and zero or one question from each other page that I link to on the course web site, making 21 equal-weight questions. The questions generally require short answers, e.g., "What happens when you irradiate polywater with N-rays?" Some may have tricks designed to benefit people who understand the topic and to catch people doing superficial pattern matching. A few may require a little extra searching, but this is an open book exam. The exam should be easy if you study.
