Occasionally I write out some of my notes and stick them here for easy access. They probably are not useful to anyone else, but if you do find them useful please let me know. Be careful: anything that you find here is probably full of typos!
Thanks to Juan Jottar for catching a typo in a previous version.
A quick and dirty review of the geometry underlying Arnowitt, Deser, and Misner's Hamiltonian approach to General Relativity.
Reference sheet for an undergraduate Particle Physics course. Unfortunately, the (+,-,-,-) signature is used throughout.
A visual reference for Murray Gell-Mann's Eightfold Way. From the same course as the particle physics formula sheet.
A LaTeX template for letters with a simple letterhead that includes your school's logo. Replace the file signature.pdf to add your scanned signature to the closing.
A simple Beamer style for presentations with LaTeX. The title page features basic info as well as a logo. The style file includes macros for putting gradients in the background of a slide, and various color boxes to use as callouts. An extensively documented example .tex file is included.
