This is called the principle of least action. We know it applies in our everyday world, and now—thanks to a new study —we know it applies in the quantum world as well.

The modern formulation of the least action principle was given by the Euler–Lagrange equation in the 1750s. Similarly, the second law of thermodynamics states that the entropy ...

Lagrange discovered what today we call the principle of least action. All physical laws, including Newton's laws, flow from this single unifying principle.

The principle of least action has been a key law of physics since the 18th century, but has only now been directly observed in the quantum realm thanks to an experiment with single particles of light.
