Webb29 maj 2024 · 1. 2. I first remember the principle of least action while learning about Feynman diagrams. 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. Webb1 maj 2024 · Introduction. The principle of least action (PLA) is one of the most general laws of theoretical physics and simultaneously one of the most philosophically controversial laws. Over the centuries, many scientists have linked it to hopes of a universal theory, despite the related metaphysical disputes about causality.
