in quantum mechanics, these same pairs of variables are related by the Heisenberg uncertainty principle.(adsbygoogle = window.adsbygoogle || []).push({});

The energy of a particle at a certain event is the negative of the derivative of the action along a trajectory of that particle ending at that event with respect to the time of the event.

what is the meaning ????

please explain as simply as possible.......
