Here's an updated version of the Invertible Matrix Theorem, reflecting what we've covered in Units 1 and 2.

If you're interested in checking out the Twitter bots I mentioned in class the other day, here are some links:

- @KarlMarxovChain - A Markov bot that uses the writings of philosopher Karl Marx
- @autoblake - A Markov bot that uses the writings of poet William Blake
- @BabbageBot - The Markov bot I created that uses the writings of scientist Charles Babbage
- @TwoHeadlines - This bot randomly puts together two current news headlines.
- @NSA_PRISMbot - This bot randomly generates fake NSA surveillance reports.
- @RemixMyProf - This bot takes actual tweets that include the phrase "my professor" and replaces "professor" with a randomly chosen medical professional (or "4th grade teacher").
- @WhitmanFML - This bot takes actual tweets that include the hashtag "#FML" (look it up, if you don't know what it stands for) and concatenates them with lines from Walt Whitman's poetry, joining the two pieces of text at the word "and."

For more information on Markov bots, see this short article. For some code you can use to create your own Twitter bots, see Roger Whitson's code on GitHub and this tutorial from Al Sweigart.
