31. This concept is applied in key predictions of quantum electrodynamics ( QED, see above ). 32. Despite his crucial role in the development of quantum electrodynamics , he wrote the following in 1985: 33. For the most accurate predictions in all situations, Maxwell's equations have been superseded by quantum electrodynamics . 34. In particle physics, quantum electrodynamics ( QED ) is the relativistic quantum field theory of electrodynamics. 35. This has led to the theory of quantum electrodynamics , arguably the most successful theory in physics. 36. Surely quantum electrodynamics was so named as a play on Q . E . D .. 37. The first complete quantum field theory, quantum electrodynamics , provides a fully quantum description of the Coulomb potential. 38. An example is quantum electrodynamics ( QED ), where one finds by using beta function is positive. 39. For quantum electrodynamics the work was extended. 40.
