<t>sometimes, it hurts to know too much physics too.I did study n-body problems many years ago.

<t>All known motion is described by Hamilton's equations, and the time evolution is called a Hamiltonian flow.Brownian (aka Weiner) is defined as a random walk and its process is a stochastic flow.Hamiltonian flows and stochastic flows are mutually exclusive (very well known). So why would anyone ca...
