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.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that “my ignorance is just as good as your knowledge.”
