Hello, I'm Bongwarrior. I wanted to let you know that I undid one or more of your recent contributions to Doppler effect because it didn't appear constructive. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! --Bongwarrior (talk) 23:18, 13 March 2013 (UTC)
