# gst: Brownian motion from trading

<< The kinetic theory of molecules, involving many collisions between particles, leads to the emergence of physical Brownian motion. By generalizing the kinetic framework, the study showed the emergence of financial Brownian motion from decisions made by individual traders. >>
