Making a Robot Chainsaw. Carving dogs. https://youtu.be/ix68oRfI5Gw via @stuffmadehere
Putting a chainsaw on a robot arm, now what could go wrong with that?
(Second robot arm video today. Maybe I should revive my idea of a universal exercise machine based on 2 Kuka robots…)

I like how he CNC'd a wood demo prop for the local maximum problem of gradient [des|as]cent in order to explain both the technique and the problem to the audience. That's a commitment to explanation that's rarely seen in "professional" educators.

Gradient descent (when I learned OR we cared about minimizing things
) was invented by
[drumroll please]
Newton. Yes, that Newton.
(Technically he invented a descent method to find a function's zeros by increments, but that's the foundation of the whole thing. OR, that is.)
