Energy operator

In quantum mechanics, energy is defined in terms of the energy operator, acting on the wave function of the system as a consequence of time translation symmetry. (Wikipedia).

Teach Astronomy - Energy

http://www.teachastronomy.com/ Scientists define energy as the ability to do work. You can also think of energy as something that can cause a change. This sounds vague. But scientists have defined energy in many careful ways, and it is a clearly quantifiable concept in physics. Next ti

How Quantum Physics Explains Creation of Energy (from Outside a System) - Parth G Quantum Mechanics

The Creation and Annihilation Operators (collectively known as the Ladder Operators) are a very useful tool in quantum mechanics. We'll be taking a look at what they represent and how we can use them. Before delving into the world of quantum mechanics, we'll first be looking at an importa
