[Unified-mailman] Quiz reviews

[Mark Drela]

Folks,

As Jenny mentioned, we will be having the Fluids quiz reviews
in the Tue and Thu recitations this week.  Since there isn't
enough time to review everything in detail, I will select topics
by popular demand, in a Q&A format.  So please think about 
what you would *most* like to review.  I suggest that you 
also bring the quiz crib sheet as a handy topic list.
