For example, there's a whole museum dedicated to MIT's contributions to naval architecture. The Hart Nautical Galleries is holding an ongoing exhibit that chronicles various devices, structures and even robotic fish that the good folks at MIT have invented over the years. There's even an exhibit devoted to acoustics that shows how whales are able to communicate with one another over long distances without dialing one of those 10-10 numbers. The highlight of the show is the robotic tuna developed to explore the briny deep. You can get to the museum from the Central Square T stop.
Admission is free.
The Hart Nautical Galleries are open between 9 a.m. and 8 p.m., Monday through Friday, at 77 Mass. Ave. in Cambridge. Mass. All rights reserved.
