I went to Boston this past Sunday to participate in the rally for science. The speakers were very good and the crowd was bigger than I expected, although I'm not sure what the official count was on the number of people there.
Scientists are more subdued than "normal" protesters. Their enthusiasm for chanting protest slogans was noticeably (to me) muted. These are people who think deeply about issues and work hard to maintain a cool head - exactly the sort of people we need running our government!
