Since this is HN, I can wholeheartedly recommend the National Cryptologic Museum (between DC and Baltimore, pay really good attention to the signs so you don't make a wrong turn and having an awkward interaction with NSA Police). In addition to math stuff, there's a lot of exhibits on the history of computing that is kept pretty well up to date (when I went ~5 years ago they already had a display talking about Heartbleed).
