ThreeBody - 2.0.1

The program ThreeBody illustrates some solutions of the 3 bodies problem in celestial mechanic.

ThreeBody is an application working under Mac OS X (Tiger or Leopard). It's a scientific program for a general public: its aim is to remain us a fundamental idea, i.e. that even in the case of a perfectly deterministic problem like the law of gravitation (le law in 1/r^2 from Isaac Newton), as soon as we have more than two bodies (planets), one cannot predict the asymptotic behavior (in the long range) of the system. So one may say that even in the case of a simple deterministic situation, the liberty is still alive.
