  • Understanding electrodynamics is crucial for explaining phenomena like electromagnetic waves.

And then I guess that was then the bedrock on which Feynman and Schwinger and Tom and Arga built quantum electrodynamics, which is the first kind of complete quantum field theory.

Examples

  • He could one day work on quantum electrodynamics, which, you know, is this theory of the subatomic world and and light.

  • So he's saying that you can't use classical electrodynamics down to subatomic dimensions.

  • And then in June, he wrote a paper named Electrodynamics of moving bodies.

  • So you see now we're not really doing electrodynamics at the moment.

  • In classical electrodynamics, yeah, but it's a conserved.

  • Published a version of his famous equation in 1905 in a seminal research paper titled "On the Electrodynamics of Moving Bodies."

    Academic text (2003)
  • The research in electrodynamics focuses on how moving electric charges produce forces.

  • In electrodynamics, scientists analyze the interactions between charged particles in motion.

Morphology

electrodynamics = dynamics (semi-transparent) = electro + dynamic + s

The word is built from electro- plus dynamics, but the specialized physics sense is only partly predictable from the base word.

Etymology

Electrodynamics joins electro- and -dynamics. The electro- part comes from a Greek word for 'amber', a stone that when rubbed makes static electricity and gives us electric and electron, and -dynamics means 'force' or 'power', like in dynamic, so electrodynamics is the study of electric forces in motion.
