Quantum Electrodynamics (QED)

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's why it's called quantum theory, we are showing how particles, or quanta, run the whole show. The electromagnetic force was the first one to get a facelift, so let's check out how these quantum field theories work by looking at quantum electrodynamics!Watch the whole Modern Physics playlist: http://bit.ly/ProfDavePhysics2Classical Physics Tutorials: http://bit.ly/ProfDavePhysics1Mathematics Tutorials: http://bit.ly/ProfDaveMathsGeneral Chemistry Tutorials: http://bit.ly/ProfDaveGenChemOrganic Chemistry Tutorials: http://bit.ly/ProfDaveOrgChemBiochemistry Tutorials: http://bit.ly/ProfDaveBiochemBiology Tutorials: http://bit.ly/ProfDaveBioEMAIL► [email protected]► http://patreon.com/ProfessorDaveExplainsCheck out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!Amazon: https://amzn.to/2HtNpVHBookshop: https://bit.ly/39cKADMBarnes and Noble: https://bit.ly/3pUjmrn Book Depository: http://bit.ly/3aOVDlT Learn more about your ad choices.
