dynamics in space

Lately, I saw on BBC world an interview with Steve Nash, an NBA basketball player on the importance of practice, practice, practice. Then, I went to see a video on youtube.com about his skills in action, and it was stunnning to see how much control he had about his body and the direction of the basketball. In the interview he also used a lot of mathematical terms, like "linear", "equation", "equilibrium". I conclude that his perception on movements and forces must have been very sharp. Whatever it is that controls our movements or allows reflection on it, our machineries to process laws of mechanics come back in many other realms as well, such as in economy (growth and output curves), thermodynamics (entropy and energy) or recently in collaborative systems.
