Consider two electrons that interact with each other. classically, their interaction would be described in terms of the electrostatic force. in quantum mechanics, their interaction is interpreted in terms of emission and absorption of photons: one of the two electrons emits a photon with energy δe, which is then absorbed by the other electron after a short period of time. how long can the photon survive before it is absorbed without violating the uncertainty principle?
