WebPhysicist Richard Feynman won his scientific renown through the development of quantum electrodynamics, or QED, a theory describing the interaction of particles and atoms in radiation fields. As a part of this work he invented what came to be known as "Feynman Diagrams," visual representations of space-time particle interactions. WebMar 8, 2016 · Electrons or positrons (same as electrons with a positive charge) are real particles, a small ripple in the electromagnetic field. Virtual particles, on the contrary, are disturbances that can not be created on their own and have to be the result of real particles or fields interacting with each other. In fact, virtual particles are not ... procyclingstats consonni
