As the list of lectures and papers given over a long career will indicate,
I have prepared presentations on a wide variety of subjects over the past four and a half decades.
Beginning around 2006, I began using Power Point. Fifteen sample Power Point presentations from the past eleven years,
in pdf form, can be found on the "Select Power Point Presentations" page.
