Wesleyan, NYU CAS and GW Elliott School

My son is doing his revisits at three schools to which he was fortunate enough to be accepted: Wesleyan University, NYU College of Arts and Sciences, and the George Washington University Elliott School of International Affairs. He is interested in astronomy, economics and international relations (not fully decided, and I suspect he will not be fully decided by May 1). He had originally leaned toward NYU because of the New York City campus and access to internships and international campuses, but was pleasantly surprised to be admitted to Wesleyan and is also intrigued by the small liberal arts college experience. Any reactions or advice would be welcome. I don’t think he can make a bad choice, but he really wants to make the best choice.

Interesting choice for a possible astronomy major since an observatory is the most prominent architectural feature on campus and Wesleyan purchased its first telescope in 1835. By 1869, it was already in possession of the second best instrument in the United States, behind only Harvard’s (Potts, David, Wesleyan University, 1831-1910, p.78.)

Nowadays, most research is done off-campus in conjunction with major research universities around the world. And, get this: A NASA sponsored study of the mysterious interstellar clouds surrounding the galaxy is being led by a Wesleyan undergraduate:
