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.
