5.2, due February 16

First of all, can I just point out how awesome it is that the author used the phrases "honest-to-goodness" and "if doing this makes you uncomfortable"?  When I read each of those lines, I laughed right out loud.  As far as the math of this section goes, it really isn't all that hard...until you get to page 127. Once I got to that point, I was lost.  The math started to get more theoretical and less concrete.  I was waiting for an example to explain the theorems but there wasn't one! It kinda left me hanging....
