December 2017 edit

  Hello, I'm DVdm. I noticed that you made a change to an article, Old quantum theory, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. DVdm (talk) 15:54, 2 December 2017 (UTC)Reply

Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article. DVdm (talk) 17:26, 2 December 2017 (UTC)Reply
