In very old times, people counted – one, two, many. I want to show you now that they were right.
Let’s consider the motions of isolated bodies:
1. N = 1 - simple motion;
2. N = 2 - Keplerian orbits;
3. N = 3 - this is the difficult problem. In general, this problem can be studied only by computer simulations.
