Answer the following question: Information:  - Elliptic geometry, a special case of Riemannian geometry, is a non-Euclidean geometry, in which, given a line "L" and a point "p" outside "L", there exists no line parallel to "L" passing through "p", as all lines in elliptic geometry intersect. Elliptic geometry has a variety of properties that differ from those of classical Euclidean plane geometry. For example, the sum of the interior angles of any triangle is always greater than 180°.  - Ezra Cornell (January 11, 1807  December 9, 1874) was an American businessman, politician, philanthropist and educational administrator. He was the founder of Western Union and a co-founder of Cornell University. He also served as President of the New York Agriculture Society and as a New York state Senator.  - In mathematics, particularly in the theories of Lie groups, algebraic groups and topological groups, a homogeneous space for a group "G" is a non-empty manifold or topological space "X" on which "G" acts transitively. The elements of "G" are called the symmetries of "X". A special case of this is when the group "G" in question is the automorphism group of the space "X"  here "automorphism group" can mean isometry group, diffeomorphism group, or homeomorphism group. In this case "X" is homogeneous if intuitively "X" looks locally the same at each point, either in the sense of isometry (rigid geometry), diffeomorphism (differential geometry), or homeomorphism (topology). Some authors insist that the action of "G" be faithful (non-identity elements act non-trivially), although the present article does not. Thus there is a group action of "G" on "X" which can be thought of as preserving some "geometric structure" on "X", and making "X" into a single "G"-orbit.  - In Riemannian geometry, the sectional curvature is one of the ways to describe the curvature of Riemannian manifolds. The sectional curvature "K"() depends on a two-dimensional plane  in the tangent space at a point "p" of the manifold. It is the Gaussian curvature of the surface which has the plane  as a tangent plane at "p", obtained from geodesics which start at "p" in the directions of  (in other words, the image of  under the exponential map at "p"). The sectional curvature is a smooth real-valued function on the 2-Grassmannian bundle over the manifold.  - Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.  - Andrew Dickson White (November 7, 1832  November 4, 1918) was an American historian and educator, who was the cofounder of Cornell University and served as its first president for nearly two decades. He was known for expanding the scope of college curriculae. A politician, he had served as state senator in New York. He was later appointed as a US diplomat to Germany and Russia, among other responsibilities.  - A mathematical problem is a problem that is amenable to being represented, analyzed, and possibly solved, with the methods of mathematics. This can be a real-world problem, such as computing the orbits of the planets in the solar system, or a problem of a more abstract nature, such as Hilbert's problems.<br> It can also be a problem referring to the nature of mathematics itself, such as Russell's Paradox.  - In mathematics, hyperbolic geometry (also called BolyaiLobachevskian geometry or Lobachevskian geometry) is a non-Euclidean geometry. In hyperbolic geometry the parallel postulate of Euclidean geometry is replaced with:  - Cornell University is an American private Ivy League and federal land-grant doctoral university located in Ithaca, New York. Founded in 1865 by Ezra Cornell and Andrew Dickson White, the university was intended to teach and make contributions in all fields of knowledgefrom the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's motto, a popular 1865 Ezra Cornell quotation: "I would found an institution where any person can find instruction in any study."  - Euclidean geometry is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the "Elements". Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions (theorems) from these. Although many of Euclid's results had been stated by earlier mathematicians, Euclid was the first to show how these propositions could fit into a comprehensive deductive and logical system. The "Elements" begins with plane geometry, still taught in secondary school as the first axiomatic system and the first examples of formal proof. It goes on to the solid geometry of three dimensions. Much of the "Elements" states results of what are now called algebra and number theory, explained in geometrical language.  - A mathematician is someone who uses an extensive knowledge of mathematics in his/her work, typically to solve mathematical problems.  - Daina Taimina ( Latvian : Taimia ; born August 19 , 1954 ) is a Latvian mathematician , currently Adjunct Associate Professor at Cornell University , known for crocheting objects to illustrate hyperbolic space .  - Mathematics (from Greek  "máthma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.  - In mathematics, hyperbolic space is a homogeneous space that has a constant negative curvature, where in this case the curvature is the sectional curvature. It is hyperbolic geometry in more than 2 dimensions, and is distinguished from Euclidean spaces with zero curvature that define the Euclidean geometry, and elliptic geometry that have a constant positive curvature.  - Classics or classical studies is the study of classical antiquity. This covers the ancient Mediterranean world, particularly ancient Greece and Rome. It encompasses the study of ancient languages, literature, philosophy, history, and archaeology. Traditionally in the West, the study of the Greek and Roman classics was considered one of the cornerstones of the humanities and a necessary part of a rounded education. Since the 20th century, however, Classics is no longer a part of a typical elite education.  - In geometry, Euclidean space encompasses the two-dimensional Euclidean plane, the three-dimensional space of Euclidean geometry, and certain other spaces. It is named after the Ancient Greek mathematician Euclid of Alexandria. The term "Euclidean" distinguishes these spaces from other types of spaces considered in modern geometry. Euclidean spaces also generalize to higher dimensions.  - 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.
