Hello, I'm Materialscientist. I noticed that you recently removed some content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Materialscientist (talk) 12:49, 4 August 2012 (UTC)
