10.5 up to Theorem 10.18, due on November 12

DIFFICULT
I'm not fully understanding this Restriction business, why we need it and what help is provides and how it correlates with Theorem 10.18.  Trying to understand Theorem 10.18 is a little odd.  I hope that this will be clarified in lecture tomorrow.

REFLECTIVE
Some things are familiar from earlier sections in the chapter.  We have talked about Cantor earlier this book when we talked about denumerability.  This section seams to be pretty difficult, good thing we are spending two lectures on it.
