The first part of homework 4 is posted in the Assignments tab. You should get started on it; it’ll be a longer assignment than usual since it covers three lectures of material and you have a week and a half to do it.
Also, come to office hours tomorrow to get your old homeworks (and if you have questions, of course).
Also also, the next exam is tentatively scheduled for Wednesday, 23 October 2013, and will cover chapter 3.
Also also also, how dope is Gursky?
