Hello,
As we mentioned today, Johanna, who was scheduled to come tomorrow, is sick. We will instead use tomorrow (Tuesday) as a seminar to discuss the recent lectures, and leave Wednesday for you to catch up on reading, and to work on Assignment 3. We expect that Johanna will instead be able to come on Monday 26th, and Patrick Kratt will be rescheduled into a space Section 4 (so you will not miss any of these important lectures, don't worry)!
See you tomorrow...
Christian and Cecilia
