# Talks

In 2007, I started experimented with posting material related to my presentations on my webpage. The LaTeX package, beamer makes excellent documents for presentations. However, in many situations, I find a chalk-board talk more effective and only prepare hand-written notes for myself. I plan to continue posting material for my talks on this page for the moment, but I've found two major problems. First, there is an enormous amount of repetition in my formal presentations using beamer documents. Second, my informal notes for chalk-board talks can be very messy.
