Abstract

Looking through my files, I find that I gave 13 lectures in 2016, or just over one a month. Using that number as a rough annual average, this would imply somewhere over 400 lectures during the course of my career, though this could be off by 100 or so, plus or minus. Each of those lectures involved several hours of prep time, and some few involved tens of hours of preparation, so I've devoted a fair amount of my life to their creation and presentation.
