This shows that viewing <electromagnetism> as <gauge theory> does have experimentally observable consequences. TODO understand what that means.

In more understandable terms, it shows that the <magnetic vector potential> matters where the magnetic field is 0.

Gravity and electricity by Hermann Weyl (1918)

{wiki}

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.
