Students and professors may joke that this Midwestern university is “where fun goes to die,” but that rigor has also propelled the school to produce 49 Rhodes Scholars, 87 Nobel Laureates, and nine Fields Medalists. It’s also home to the world’s first self-sustaining nuclear reactor, Chicago Pile 1, which was constructed in 1942 beneath the stands of the school’s little-used football field (the school’s sports have rarely ranked on any global list). These days, Chicago is perhaps best known for its economics department (No. 4 in the world), which is so ubiquitous in the field that it has an entire school of thought named after it.
