Problem: Information: - The Ivy League is a collegiate athletic conference comprising sports teams from eight private institutions of higher education in the Northeastern United States. The conference name is also commonly used to refer to those eight schools as a group beyond the sports context. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, the University of Pennsylvania, Princeton University, and Yale University. The term "Ivy League" has connotations of academic excellence, selectivity in admissions, and social elitism. - Lake Erie is the fourth-largest lake (by surface area) of the five Great Lakes in North America, and the thirteenth-largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is deep. Lake Erie's northern shore is bounded by the Canadian province of Ontario, with the U.S. states of Ohio, Pennsylvania, and New York on its southern and easternmost shores and Michigan on the west. These jurisdictions divide the surface area of the lake by water boundaries. The lake was named by the Erie people, a Native Americans people who lived along its southern shore. That Iroquoian tribe called it ""Erige"" "("cat")" because of its unpredictable and sometimes violently dangerous nature. It is a matter of conjecture whether the lake was named after the tribe, or if the tribe was called ""Erie"" because of its proximity to the lake. - New Jersey is a state in the Northeastern United States and mid-Atlantic regions of the United States. It is bordered on the north and east by New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, and on the southwest by Delaware. New Jersey is the fourth-smallest state but the 11th-most populous and the most densely populated of the 50 United States. New Jersey lies entirely within the combined statistical areas of New York City and Philadelphia and is the third-wealthiest U.S. state by per capita income as of 2014. - The Pennsylvania State University (commonly referred to as Penn State or PSU) is a public, land-grant, research-intensive university with campuses and facilities throughout Pennsylvania. Founded in 1855, the university has a stated threefold mission of teaching, research, and public service. Its instructional mission includes undergraduate, graduate, professional and continuing education offered through resident instruction and online delivery. Its University Park campus, the flagship campus, lies within the Borough of State College and College Township. It has two law schools, Penn State Law, on the school's University Park campus, and Dickinson Law, located in Carlisle, 90 miles south of State College. The College of Medicine is located in Hershey. Penn State has another 19 commonwealth campuses and 5 special-mission campuses located across the state. Penn State has been labeled one of the "Public Ivies," a publicly funded university considered as providing a quality of education comparable to those of the Ivy League. - Pennsylvania (Pennsylvania German: "Pennsylvaani"), officially the Commonwealth of Pennsylvania, is a state located in the northeastern and Mid-Atlantic regions of the United States. The Appalachian Mountains run through its middle. The commonwealth borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east. - George Washington Atherton ( June 20 , 1837 -- July 26 , 1906 ) was president of the Pennsylvania State University from 1882 until his death in 1906 . He earned a degree from Yale in 1863 and taught at universities such as the University of Illinois and Rutgers before accepting the position of president at Penn State .
