Hello, I'm Widr. I wanted to let you know that I undid one or more of your recent contributions to Bernoulli's principle 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. Widr (talk) 18:16, 12 January 2013 (UTC)
