## Are the Feynman Lectures available on video?

If you want to enjoy some of the material covered in those books on video, watch Feynman deliver the first of a series of seven lectures at Cornell below in a series recorded by the BBC, in addition to several other Feynman lectures on the same YouTube playlist.

**What is QED theory?**

quantum electrodynamics (QED), quantum field theory of the interactions of charged particles with the electromagnetic field. It describes mathematically not only all interactions of light with matter but also those of charged particles with one another.

**Is QED a QFT?**

QED is a relatively simple QFT in which the only dynamic entities are the electromagnetic field and one or more fermion fields (such as the electron field). In QED, electron particles are quanta of the electron field, as suggested in the question.

### How precise is QED?

The agreement found this way is to within ten parts in a billion (10−8), based on the comparison of the electron anomalous magnetic dipole moment and the Rydberg constant from atom recoil measurements as described below. This makes QED one of the most accurate physical theories constructed thus far.

**What does QED mean?**

quod erat demonstrandum

Definition. Latin abbreviation for quod erat demonstrandum: “Which was to be demonstrated.” Q.E.D. may appear at the conclusion of a text to signify that the author’s overall argument has just been proven.

#### Are Feynman lectures good for learning physics?

maybe some physicists discount feynman’s lectures because he is explaining a way of thinking that they already have as second nature, but for me it is very helpful. also as a researcher in mathematics, i have found it useful not just to know how to do certain technical things, but why and when to do them.
