There a particle’s actual path is determined by calculating the action along all paths. All path integrals contribute to the particle’s motion with the largest integrals dominating. This is related to non-locality and is quite an amazing concept.

Over the centuries, … WebbOur simplified approach (the assumption of light traveling at the speed of light) reduces our least action principle to a least time principle: the arrows associated with the path of …
Webb5 juni 2015 · The principle of least action is the basic variational principle of particle and continuum systems. In Hamilton's formulation, a true dynamical trajectory of a system between an initial and final configuration in a specified time is found by imagining all possible trajectories that the system could conceivably take, computing the action (a … WebbAdaptive Quantum Monte Carlo Approach States for High-Dimensional Systems.
