Hi all, I'm new to the forum so I hope this is the right place to pose this question. I've managed to find answers to nearly all of the questions I've had regarding certain aspects of physics on the forums, but haven't seen this addressed anywhere. According to Wikipedia ( https://en.wikipedia.org/wiki/Proton-to-electron_mass_ratio ), there is a new "formula" that can be used to calculate the proton/electron mass ratio. Personally, I can't find any reasonining behind the use of many of the constants in this formula. Not only that, but the "source" (if it can even be called that) for the formula also doesn't seem to provide any reasoning behind the derivation: http://phxmarker.blogspot.cz/2015/08/the-razors-edge-muonic-proton-radius-in.html I'm wondering if this formulation holds any validity whatsoever. I can't put together what the Fine structure or Rydberg constants have to do with the derivation and was hoping somebody here could help make sense of it. To me, it just seems to be elaborate numerology but I'd be happy with any insight people could provide. thanks!
