Academic Alliance. The University of Chicago is not a member of the rebranded consortium, but will continue to be a collaborator. The university operates more than 140 research centers and institutes on campus. Among these are the Oriental Institute—a museum and research center for Near Eastern studies owned and operated by the university—and a number of National Resource Centers, including the Center for Middle Eastern Studies. Chicago also operates or is affiliated with several research institutions apart from the university proper. The university manages Argonne National Laboratory, part of the United States Department of Energy's national laboratory system, and co-manages Fermi National Accelerator Laboratory (Fermilab), a nearby particle physics laboratory, as well as a stake in the Apache Point Observatory in Sunspot, New Mexico. Faculty and students at the adjacent Toyota Technological Institute at Chicago collaborate with the university. In 2013, the university formed an affiliation with the formerly independent Marine Biological Laboratory in Woods Hole, Mass. Although formally unrelated, the National Opinion Research Center is located on Chicago's campus. The University of Chicago has been the site of some important experiments and academic movements. In economics, the university has played an important role in shaping ideas about the free market and is the namesake of the Chicago school of economics, the school of economic thought supported by Milton Friedman and other economists. The university's sociology department was the first independent sociology department in the United States and gave birth to the Chicago school of sociology. In physics, the university was the site of the Chicago Pile-1 (the first controlled, self-sustaining man-made nuclear chain reaction, part of the Manhattan Project), of Robert Millikan's oil-drop experiment that calculated the charge of the electron, and of the development of radiocarbon dating by Willard F. Libby in 1947. The chemical experiment that tested how life originated on early Earth, the Miller–Urey experiment, was conducted at the university. REM sleep was discovered at the university in 1953 by Nathaniel Kleitman and Eugene Aserinsky. The University of Chicago (Department of Astronomy and Astrophysics) operated the Yerkes Observatory in Williams Bay, Wisconsin from 1897 until 2018, where the largest operating refracting telescope in the world and other telescopes are located.
