The universe is always optimizing to the least amount of action.The least action principle has a rich history involving great thinkers such as Newton, Lagrange, Fermat, Euler, Maupertuis, and Hamilton.Maupertuis faced ridicule but was ultimately proven right, showcasing the recurring theme of history and science.Small changes have minimal impact in the universe, leading to the exploration of quantum mechanics and the possibility of a least action explanation.
