The final is takehome final I will post problems on
Thursday Dec.7 at about 10 AM. The exam is due on Friday Dec. 8^{th}
at 5 PM. You will need to return your work to Hassan (He will be
in his office JFB 212A at 45 PM) or in my mailbox in
the department office. I the latter case you need to ask office attendant to
put a time stamp on your work. 
The final will include one
simple problem on density matrix and one simple problem on nonequilibrium
SM. The other problems will cover material of MT01 and MT02 and will be more
involved. 
IMPORTANT FOR ME
(and future students) Please answer the
questions about the content of the course and return the question sheet. alongside with
your final. Your work on the final must
be strictly independent. No group study or consultations with other people
are allowed. We will cross check your solutions. 
Labor Day holiday Monday, September 3
