2.6 Mutual Attraction - The Nature of Code

TL;DR

Explore interactive gravitational N-Body simulations with attractor dynamics and Euler integration.

Transcript

Welcome to another nature of code video.   This one is all about mutual attraction  and the N-Body problem. Now, I don't know   how you arrived here. This is a followup to the  previous video about gravitational attraction,   but I'm actually making it all those two years  later. I just watched the end of that video. So I think I know if you're wat... Read More
