collision-production mode

That is the official status of LHC now. http://home.web.cern.ch/about/updates/2015/06/lhc-experiments-back-business-record-energy Thought, it would be okay to mention it at that spot over at LHC. Though, it is not that important. (I think i added a ref for it too) prokaryotes (talk) 13:06, 4 June 2015 (UTC)[reply]

That phrase was used for April where no (relevant) collisions occured. I'm fine with using it for now, as we now have collisions. --mfb (talk) 17:42, 4 June 2015 (UTC)[reply]

EM Drive

Hi mfb,
You haven't been following this very closely have you? You ask Then where would the momentum of the EM wave come from, if not from the apparatus initially? Answer F=2P/c... Google it. Ask NASA and the other five counties that are studying the EM Drive. If you question the math, post it on the talk page or Wikipedia:Reference desk/Mathematics but don't revert unless you have reason Sutor, ne ultra crepidam. So don't take offense that I am reverting your edits. --Aspro (talk) 22:09, 5 September 2016 (UTC)[reply]

If the satellite is able to accelerate by purely internal mechanisms, this violates conservation of momentum. The details of where in the satellite the momentum is do not matter. Everyone agrees that it violates conservation of momentum unless there is some exhaust in some way. --mfb (talk) 22:19, 5 September 2016 (UTC)[reply]

Which part is unclear? --mfb (talk) 11:45, 6 September 2016 (UTC)[reply]

Muonium

I don't understand the reason for your change of 16 September. It is the case that uncertainty related to the structure of the proton limits the precision of calculations of the energy levels of hydrogen. If the original statement was unclear, I would be happy to change it, rather than undo your change. — Fcy (talk) 04:33, 29 October 2016 (UTC)[reply]

The old version suggests that the energy levels of muonium could be calculated more precisely than the energy levels of regular hydrogen. That is not true. The largest source of uncertainty in both cases is the proton size and structure - this uncertainy is much more important for muonium. Muonium is used to measure the proton radius for this reason. --mfb (talk) 10:46, 29 October 2016 (UTC)[reply]

You're thinking of muonic hydrogen, in which the electron of hydrogen is replaced by a negative muon, rather than muonium, in which the proton is replaced by a positive muon. —Fcy (talk) 16:31, 29 October 2016 (UTC)[reply]

Oops. Reverted my edit, thanks. --mfb (talk) 16:38, 29 October 2016 (UTC)[reply]

Dimensionless Constants

Please read the talk page. We are having a disagreement (deletion of Jim Johnson reference)and I would like your opinion.Thanks Jim Johnson2602:304:B10B:A640:40A9:7E78:F78E:8DA2 (talk) 01:22, 20 November 2016 (UTC) I mean Dimensional Physical Constants.
