You don't need to be science-savvy to enjoy a trip to the MIT Museum. And every last Sunday of the month through June, you won't need a dime either. One of the newer exhibits, 5000 Moving Parts, looks at kinetic art, i.e. things that move unpredictably. And if that's not your thing, well, no big deal, the museum has robots and holograms and stuff too.
January 26, MIT Museum, Building N51, 265 Massachusetts Ave., Cambridge, 617-253-5927, mit.edu.
