Homework 2 (assigned 9/04, due 9/05 11:30 PM)

Use NB to annotate the following two files:

a) AngEtAl.pdf: 

   - follow instructions for reaction commentaries (except for deadline)

b) OptionalPaperSignup.pdf:
   
   - sign up to be responsible for briefly summarizing/evaluating two
     papers that only you will have mandatorily read (for two
     different classes, and not a class you are already leading). Read
     the instructions for optional papers to learn more.

     - annotate your name next to one of the optional papers that I
       have already listed in the file.

     - annotate your name next to the title of a different class, to
       indicate that for this discussion you (rather than me) will
       find an optional paper to present.

   NOTE: Only one person can sign up for any given class!
