Why do we do proofs? - Dr Joel Feinstein

My three screencasts on proof were produced using a combination of Camtasia, LaTeX Beamer class, and Windows Journal on my tablet laptop. As you can read in my blog "Explaining Mathematics" (see link in the description above), this procedure works better if the laptop is running on mains power, rather than on battery power. The two screencasts on "How do we do proofs?" were recorded with the tablet using mains power, while this screencast was recorded using battery power. Joel Feinstein
