Jackson's Classical Electrodynamics, but hidden underneath it would be Griffiths' Intro to Electrodynamics
omg. Kat Abughazaleh just posted that if she's elected, she'll swear in on a copy of Octavia Butler's Parable of the Sower.
If you were elected to public office (never mind whether you'd ever actually run), what book would you swear in on?

It has become tradition among my friends for the officiant to hold Jackson’s Classical Electrodynamics during weddings.

I had three jokes about quantum electrodynamics but it turned out they’re all the same joke
I have a joke about Occam’s razor but you guys will overthink it.
I have a joke about Fermat's Last Theorem but it's too long to fit in the margin here.

Using the N-word in a non-racial way is like using is like using Quantum Electrodynamics in a non-scientific way.
A Scottish Tory peer has spoken out in defence of using the N-word.
Nigel Biggar argued in a blogpost that it is 'stupidly unjust' for people to be punished for using the N-word if they did not mean it in a racist way.

Here is a thread about tiny discrepancies, the marvelous predictive power of Quantum Electrodynamics, and the sort of immigrant success story that the current administration is doing everything in their power to eliminate. 🧪 ⚛️
Physicist Polykarp Kusch was born #OTD in 1911. His measurements of the magnetic moment of the electron revealed that its value disagrees with naive predictions by a tiny amount — about 0.1%.
Quantum Electrodynamics offers a marvelous explanation of this minuscule discrepancy. 🧪 ⚛️

The irony here is that, in my view, the most elegant introduction to SR is via electrodynamics. It feels clean and inevitable, uses familiar calculus, and also hints at the horrifying complexity of GR.

I know I'm not the only one to have noticed the fact that many- indeed most - such correspondents are Electrical Engineers (usually retired). I was delighted therefore to see that there's now a nice little paper on arXiv by David Garfinkle with the title Relativity for…

I wrote the equations on the blackboard behind Oppenheimer for one scene in Fat Man and Little Boy. I based them on the lecture notes for his electrodynamics class.

Freeman Dyson submitted a lovely little two-page paper to Physical Review #OTD in 1951. It showed that perturbation theory in quantum electrodynamics produces a divergent series. It's one of my favorites, an absolute classic of the field. 🧪 ⚛️

But my favorite bit of field theory work by Dyson is his short, beautiful paper – two pages! – showing that perturbation theory in quantum electrodynamics produces a divergent series.
It is a fantastically simple and elegant piece of reasoning. A real classic. (6/n)

Divergence of Perturbation Theory in Quantum Electrodynamics
An argument is presented which leads tentatively to the conclusion that all the power-series expansions currently in use in quantum electrodynamics are divergent after the renormalization of mass and ...

This is a mind-blowing podcast.
NASA is bringing Hal Puthoff and other experts together to talk UAP physics: extended electrodynamics, zero-point energy, and advanced propulsion.
This podcast shows that a whole hidden world of UAP research is emerging.
