2.9-2.11, due on September 14

The Interesting

I liked reading about these random number generators. I have used random number generators in many statistics classes to help simulate real life, but I've never stopped to wonder how they work. 

The Challenging

I have a hard time connecting the theory and logic of linear congruential generators to the symbols they use to talk about it, which made it really hard to understand the second half of 2.10. Also, I don't really understand how to calculate how long it would take computers to decrypt something and why it's best if it's logarithmic. In 2.11, my main question is understanding the different equations they show, how they connect to the different matrices, and how to find the period (what is the period?). However, I think these things will make a lot more sense after I hear them explained in class.
