Hello, I'm GrayStorm. I wanted to let you know that one or more of your recent contributions to Cherenkov radiation have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective.
