19.1 & 19.2, due on November 16

Interesting

My husband and his brother talk about Quantum science all the time. They think "Flatland" by Dr. Quantum is fantastic, so I've watched it with them many times. It was fun seeing the quantum science being used for cryptography!

Challenging

I didn't relate very much to the polaroid example because I don't know what it means for the filters to have vertical or horizontal polarization, but it was still really cool. Also, what does orthogonal mean? By the end of the first section, I was basically reading another language.

To be honest, the key distribution of 19.2 seems really magical and mythical; I don't really understand how it works and why Alice would be able to see Bob's string any differently than Eve would observe.
