I'm trying to fix up this article a bit, to make it better express standard views on physics, and to provide references for all the claims made. I'm a mathematical physicist and an expert on general relativity and quantum field theory, so I think I can do this. John Baez (talk) 12:35, 6 September 2016 (UTC)[reply]

better explanation possible?

The text says:

...In the Reissner–Nordström metric, which describes electrically charged but non-rotating black holes, there is a quantity r_q, defined by ... Since this (vastly) exceeds the Schwarzschild radius, the Reissner–Nordström metric has a naked singularity.

It would be great if r_q could be motivated a bit, what is it?--Haraldkir (talk) 12:16, 24 February 2019 (UTC)[reply]

Black hole muon?

Im curious if these calculations generalize to the other charged leptons such as the muon? 87.63.114.242 (talk) 05:37, 21 September 2023 (UTC)[reply]

Nonrelativistic gyromagnetic ratio is 2.

According to the linked wiki entry (https://en.wikipedia.org/wiki/Gyromagnetic_ratio#Gyromagnetic_ratio_for_an_isolated_electron), the gyromagnetic ratio is 2 even if special relativity is ignored. Therefore

This is interesting because calculations ignoring special relativity and treating the electron as a small rotating sphere of charge give a magnetic moment that is off by roughly a factor of 2, the so-called gyromagnetic ratio.

is not correct and should be modified to:

This is interesting because calculations treating the electron as a small rotating sphere of charge give a magnetic moment of 2, the so-called gyromagnetic ratio.

Or do I miss something? 98.35.204.45 (talk) 19:51, 28 October 2024 (UTC)[reply]
