Bordeaux has a question on Problem 10 of the homework.

Schedule and Appointments

My door is generally (not perpetually) open, and you are usually welcome to enter when it is. However, I ask that you try to keep to posted office hours, or make an appointment for an alternate time (email is generally best), whenever possible. Occasionally I will either be out of the office or otherwise unavailable; these will generally not be noted on the weekly schedule. Open space on the schedule does not imply availability; this is especially true during the summer months.

To make an appointment, consult my weekly meeting and teaching schedule and then email me a suggested time you would like to meet. (Note: This is a typical weekly schedule, so disregard the date.)
