#Monopoles
How many times did I rewind, rewatch/
off the top of my head, I remember that magnets have a north and a south pole. If you cut one in half, a new pole forms at both ends of the shorter magnets. Keep cutting, smaller and smaller. The poles keep appearing at both ends. How small can you keep this going - to the atomic level? Can you reduce a magnet to just one pole (monopole)? Now I have to rewatch to see what his answer was. It took me forever just to grasp the question.

I also (finally!) can remember piezo-electric, but only after learning the Greek, piezo, means to squeeze or compress. Squeeze a crystal, and a spark flares to life. Hence, ignitions to cars and gas stoves. This, I can grasp.

But this new video, hosted by Keating - oh man. There's a LOT to hear, process, internalize, try to remember!
