Reliable sources[edit]
Hello, I'm DVdm. I noticed that you made a change to an article, Photon, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation 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. See also wp:secondary sources. - DVdm (talk) 18:20, 25 May 2013 (UTC)
