A mindblow moment to start your day off right:

In a system of n elastically-interacting objects, conservation of energy is an ellipsoid in 2n-dimensional (linear+angular) velocity space.

Take a moment to think about that and understand it.

@Felthry I saw a YouTube video on this, modeling a weird system of elastic collisions to count the digits of Pi. It was so hecking cool.

@starkatt Seeing that video is what made us realize that, actually!
