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 Lorentz factor, 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) 21:34, 3 June 2013 (UTC)
