If you are anywhere near DC this weekend the USA Science & Engineering Festival takes place on Saturday and Sunday. The schedule includes exhibitions, stage shows, and a monster book fair, with literally hundreds of events and exhibits taking place. A few of the events I am looking forward to are the Stargazing Party at the Air and Space Museum with Bill Nye and a team from Celestron, and of course the Mythbusters presentation. I am really going to have to restrain myself at the Book Fair, or you might find me collapsed under the volumes as I try to get them home using the Metro.
