More precisely, each generator of the corresponding Lie algebra leads to one separate conserved current, such that a single symmetry can lead to multiple conserved currents.
This is basically the local symmetry version of Noether's theorem.
Then to maintain charge conservation, we have to maintain local symmetry, which in turn means we have to add a gauge field as shown at Video "Deriving the qED Lagrangian by Dietterich Labs (2018)".

Of course those racist Nazis are a bunch of idiots, but how can you be surprised when freedom-of-speech focused tech gets used by them? www.theverge.com/2019/7/12/20691957/mastodon-decentralized-social-network-gab-migration-fediverse-app-blocking
Obviously, a few large instances dominate the user base for all practical purposes: kevq.uk/centralisation-and-mastodon/. And likely the network splits into hate-speech/non-hate-speech blacklist boundaries. And since the dominating closed networks will never lose user counts (???), the only instance that dominates will be the main hate speech one.
The flagship instance was mastodon.social and then in 2020 they closed signups for it and created a secondary mastodon.online.
The multi-instance thing is confusing and problematic. E.g. replies and likes might not show up across instances in some occasions: www.reddit.com/r/Mastodon/comments/ynt7ta/is_there_a_way_to_see_post_replies_displayed_on/
The "advanced interface" feature is bad. Really bad. MacOS file browser inspired.
The key initial quantum electrodynamics experiments:
Einstein for the theoretical explanation of the photoelectric effect from 1905, notably published as on a Heuristic Viewpoint Concerning the Production and Transformation of Light by Einstein (1905).
To Peter D. Mitchell for the discovery of the mechanism of ATP synthesis in the mitochondria, a central part of cellular respiration.
But too insane, and did not keep up with internet age, and so Ciro wants to kill it now.
Also sometimes called helium II, in contrast to helium I, which is the non-superfluid liquid helium phase.

TODO is there any relationship between this and the Josephson effect?
Experimental observation published as Experimental Evidence for Quantized Flux in Superconducting Cylinders.
This appears to happen to any superconducting loop, because the superconducting wave function has to be continuous.
Video "Superconducting Qubit by NTT SCL (2015)" suggests that anything in between gets cancelled out by a superposition of current in both directions.
Islam has some really nice things in it.
Ciro Santilli especially appreciates the ideas of
