Ping-Pong Physics and Vlogging
One of my favorite results from Classical Mechanics has to do with the stability of rigid bodies as they rotate about certain axes. I demonstrate this theorem in a YouTube video, which is my first attempt at vlogging (though these words may render my attempt but a partial one!). Click on the video below (or click here) to see and hear me talking about rotating ping-pong paddles. If you don't own a ping-pong paddle, try my demonstration at home with your television's remote control. You should easily be able to find the axis about which rotation is unstable. That's how I discovered one of nature's beautiful workings when I was a teenager.
