... - A unit or quantum of light a particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy. Ground State - The lowest energy state of a quantized system. Excited State - A state in which an atom has more energy than it does at its ground state. Emission-Line Spectru ...

INTRODUCTION TO ELEMENTARY PARTICLE PHYSICS
... However, some general features of this behavior have nothing to do with the detailed form of the interactions. Instead they follow directly from relativity, from quantum mechanics, or from the combination of the two. For example, in relativity, energy and momentum are always conserved, but (rest) ma ...

Quantum Theory
... When two particles or events affect each other without any signal or force. Determinism, and our common sense, says that this is totally impossible. Quantum mechanics predicts when it will or will not happen, and what the probability of the outcome will be. ...
