I ran into a description of harmonic drives earlier. I hadn’t seen anything quite like them before, and they are just so cool – flexible driven gear for high torque, high fraction engagement, and inherently loaded for zero-backlash. Even though there is a little marketing in it, this description is really better than wikipedia’s. I love it when neat things just appear in my field of awareness.

I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. It’s when you know you’re licked before you begin but you begin anyway and you see it through no matter what. You rarely win, but sometimes you do.
