Highlights include a geometric sector designed by Galileo, electrical experimentation apparatus purchased on Harvard's behalf by Benjamin Franklin, a suite of clocks illustrating the development of modern synchronized time-keeping, medical apparatus designed, in part, by Charles Lindbergh (yes, that Charles Lindbergh), and the artifacts of top-secret research conducted by Harvard scientists during World War II. Check the second floor gallery for the special exhibition "Measuring Difference" illustrating what—and who—was measured in the Americas.
