Notes and Miscellany
PS A walk thorugh Agrawal et. al's paper "PRIMES is in P". One or two formulas differ slightly from the linked paper, since I started writing this when they were at version 3 of the paper, and now it's at version 6. All differences are slight optimizations, and don't affect the proof in any way. I presented this in Algebra class, winter '06.
HTML A presentation on my work with the algorithmic uncertainty principle.
PDF Notes I took during John Baez's class on algebraic topology.
PDF Slides about the Rosetta Stone paper above; there are notes.

HTML Stuff I've put online that I later realized was wrong.

Other stuff
Art Songs, drawings, illumination, essays, and puns.
Miriam's music My wife Miriam's albums. I particularly like Summertime and Sing, Sing.
Family A few nice pictures of us.
Cristian Calude A picture of my advisor and me.
Science toys Cut it out, put it together, and wonder at the universe.
Scripts Javascript source code and greasemonkey scripts.
