Sum over paths

Web15 Jul 2024 · The path that has the least action just contributes the most. To get your measurement prediction, you have to sum over all these random paths. This is called … Web12 Jan 2006 · So, what is this sum over paths? Feynman's theory assigns a complex number to each path. Technically, it is the exponential of [math]i=\sqrt{-1}[/math] times the "action". In turn, the action is the integral of the Lagraingian over the path (or if you prefer to remain covariant, the Lagrange density integrated over space-time):
