Energy-time uncertainty

The energy-time uncertainty principle is not only different from the usual position-momentum uncertainty relation, it cannot be derived in the same way. This video describes a derivation in terms of the time derivative of an expectation value. (This lecture is part of a series for a course based on Griffiths' Introduction to Quantum Mechanics.
