14. And speaking of MIT, it's worth a visit. The Cambridge campus, just a mile and a half southeast of Harvard on Mass Ave., dates to 1916, when the college moved across the river from Boston. Unlike the close quarters of Harvard Square and the grittier bar scene near Central Square, the MIT campus and neighboring Kendall Square are full of big, bold and often cold modern buildings designed by avant-garde architects such as Alvar Aalto, I.M. Pei and Eero Saarinen. Even though you can find several snazzy restaurants and lively pubs in the neighborhood (notice the periodic table menu at Miracle of Science), you couldn't call MIT warm and fuzzy. On campus, most buildings are known by numbers instead of names, even the grand entrance, a.k.a. Building 7. And though MIT officials claim they operate only one nuclear reactor, half the structures on campus seem likely spots for boron neutron capture therapy or other nuclear chores.
