Hello, I'm DVdm. I wanted to let you know that I undid one of your recent contributions, such as the one you made with this edit to Michelson–Morley experiment, because it didn’t appear constructive to me. 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) 12:44, 27 October 2013 (UTC)
