Section 19.1-19.2, due on November 20

1. How do Alice and Bob establish the bases they are working with? I didn't understand that from the reading.

2. I haven't taken a physics class is four years, so it was fun to revisit that area. I also knew what polarization looked like because 3D movie glasses are often polarized. When you put one of those lenses perpendicular to another lense, you can't see through them. I was really interested to find out that this concept can be used to establish a key.
