Last brain-burner, midterm, think announcement of Fall 2007

So we want to start ultra-fast, minimum possible delay.
Have your calculator ready to go as soon as you sit down. The calculations themselves are not tricky, but we want to do them as rapidly and accurately as possible so that you have time to THINK!
Also: I am only going to make two time announcements: 15 minutes to go and 5 minutes to go. This will cut down on distraction.
