Recent advances in quantum electrodynamics (QED) have enabled scientists to calculate the energy of an electron with unprecedented accuracy. This is made possible by taking into account the effects of the electromagnetic field on the electron’s energy and momentum. The result is a much more precise calculation of the electron’s energy than was previously possible, which could have implications for the development of new technologies. This breakthrough could also help researchers better understand the behavior of electrons in different materials.
