What is quantum electrodynamics (QED)?
Quantum electrodynamics (QED) is the theory of quantum field explaining how electrically charged particles interact with each other through the replacement of photons (light "quata" or small packets of light). Photons, and therefore interaction in QED spreads at the speed of light. QED is referred to as the theory of breakup, with a mathematically specified measuring field representing electromagnetic power. Theory also explains magnetism because magnetism and electricity are two manifestations of the same basic force, electromagnetism. It was found that one forecast of QED was accurate up to 0.0038 parts per million, probably the most accurate and accurate physical forecast ever created. Calculating the right solutions to the behavior of systems with interacting parts or larger -electron orbitals increase exponentially heavier with increasing the number of components, while some calculations require literally decades to calculate and verify. Theory has been developed to satisfaction at the end of the 1940s, thanks to an independent work withIn-Itiro Tomonaga, Julian Schwinger and Richard Feynman. They won the 1965 Nobel Prize for physics for their efforts.
If electromagnetism was the only force of nature in space, QED would offer a complete description of its exact nature. However, it is not and search continues to the theory of quantum field that integrates all four forces. In addition, the solution of equations in QED is more difficult, more difficult than conventional quantum mechanical problems, because QED is the generalization of quantum mechanics to special relativity. The images most great with QED are Richard Feynman's feynman diagrams that use direct and grids to analyze different ways to exchange photons to physically interact.
The theory of QED still produces mathematical infinity in certain contexts, and while many of these problems have been solved, they persist at a certain level. ad hoc RenormalIsaration algorithms have been developed to exterminate these theoretical imperfections. These infinity suggest that QED is by no means a final theory, so the future is an open discovery of a more accurate theory that considers electromagnetism in connection with the other three natural forces.
