- 05:3305:33, 11 September 2024 diff hist −1,064 Wave equation Undid revision 1245082638 by Chumpih (talk) Not really a valid reason to revert the entire edit as "potential" is used in the orignal version as well, i.e., the edit is still an improvement. I'll change the phrasing in the next edit though. Tag: Undo
