<p>The overall atmosphere at Yale is not just about the colleges themselves, it's how they are arranged on the campus. Yale's dorms are no more than 2-3 minutes away from each other; most are right across the street. In fact, Yale has the most compact undergraduate dorms in the Ivy League. That means the students there can pretty much go anywhere and run into everyone they know, on literally any trip from one end of the campus to the other. Because of the compactness, the campus is buzzing with life 24/7. Yale is really unlike any other campus I've visited in the U.S. because of that.</p>
<p>In contrast, to use just one example, at Harvard some of the dorms are a 15 minute hike from the other dorms. That may not sound like a huge difference but it is actually a massive one when you consider 10 excursions per day from the vicinity of one dorm to another (for fun, for a class, for a meal, whatever) - that would take 20 minutes per day at Yale, versus over two hours per day at Harvard. The result of a more spread-out campus, like Harvard's, is students simply don't go out and see each other as much. At Cornell it's more like 30 minutes. That kind of situation kills campus life. It's not something you really notice until you visit a few different campuses for some length of time.</p>
<p>This kind of collegiality extends to faculty, research opportunities, grad students, etc., as well. Since Yale is in a smaller city, most of the faculty live within walking distance of the campus (60% live within the central town area of New Haven), or, at most, a 10 minute drive. At universities in larger cities such as Chicago, D.C., or New York, it's likely that many of the faculty live an hour away. That means they're much less likely to be on the campus at times when they don't really have to be (in the evenings, or on days when they don't have to teach). With the grad schools, to use examples again, Harvard and Cornell have great medical campuses but they are in totally different cities. Yale's is a short walk from the central campus, and is like a city into itself with tens of thousands of people. That means research opportunities are right there. Same goes for Yale's arts schools, museums, law school, etc. - they are literally situated right among all of the undergraduate dormitories, if not literally connected altogether. Obviously, there are a few schools out there are also compact (Wesleyan, Dartmouth, etc.), but none of them have even 1/50th the resources of Yale.</p>
<p>In that sense, Yale combines the best attributes of a small community with the resources of a great urban university. It definitely has to do with the colleges, but it also has a lot to do with how the place is laid out.</p>
