Potpourri

If you’re looking for a quick study break in Boston between the three p-sets that are due tomorrow, the five clubs you chair, and the four classes you attend sporadically, then make a trip to the Mary Baker Eddy Library’s Mapparium. Open Tuesdays through Sundays from 10 a.m. to 4 p.m., admission with a student ID is only $4, with an additional $1 discount if you present your Charlie Card when purchasing tickets. Although a visit to the library is shorter and less expensive than the ride to and from, the three-story, to-scale glass globe is well-worth the trip. After a brief, patriotic, democracy-promoting audio/visual presentation, you are left to take in the globe yourself, as well as experiment with its acoustics. Stand in the middle of the walkway that passes through the southern hemisphere of vibrant-colored countries, and your voice resonates as if it were being projected in surround-sound. Whisper to friends from the other side of the world and they will hear you perfectly. A visit to this lesser-known Boston destination may only last 20 minutes, but it’s an experience that you are unlikely to find anywhere else.
