- 9/19 - Markov chains, which are introduced in Problem Set 6, #6,
have a huge range of applications. For example, they are used in
chemistry to model reactions, in economics to model asset pricing, and
in biology to model population processes. A less serious (but fun!)
application is to use this math to figure out which squares in the
game Monopoly are landed on most frequently.
Here are a couple of
*Scientific American*articles which explain more: "How Fair Is Monopoly?" and "Monopoly Revisited". You should see that the math here is basically the same as that in Problem Set 6, #6.The articles mention that "eigenvectors" are a fast way to do some of the computations; we'll be talking about those in a few weeks!

- 9/6 - Here's a nice intro to how Google uses linear systems, written by Jameel Al-Aidroos. If you're interested in learning more about Google PageRank, take a look at this article. It features a lot of ideas we'll be studying later in the semester.
