The term and idea was first introduced initialized by Hermann Weyl when he was working on combining electromagnetism and general relativity to formulate Maxwell's equations in curved spacetime in 1918 and published as Gravity and electricity by Hermann Weyl (1918). Based on perception that $U(1)$ symmetry implies charge conservation. The same idea was later adapted for quantum electrodynamics, a context in which is has even more impact.

Amazing systems programming tutorials. Whenever you Google a hard topic, his blog comes up.

Also has many great contributions on Stack Overflow: stackoverflow.com/users/8206/eli-bendersky

As of 2016, Eli worked at Google (reference). TODO before that, I had found his earlier info previously but lost it.

Eli focuses mostly on compiler toolchains.

He also has some mathematics stuff, so cute: eli.thegreenplace.net/2015/change-of-basis-in-linear-algebra/

Huge interest overlap with Ciro Santilli, e.g. he's into

Toy/test/tought experiment algorithm.

Their only undergraduate courses that matter:

Ciro Santilli has a tutorial at Linux Kernel Module Cheat.

What you would see the moving rod look like on a photo of a length contraction experiment, as opposed as using two locally measured separate spacetime events to measure its length.

The type of feeling of confusion and distrut for your sense that some Koans attempt to instill.

Ciro Santilli's preferred version of it is physics and the illusion of life.
