62Klein bottle — In mathematics, the Klein bottle is a certain non orientable surface, i.e. , a surface (a two dimensional manifold) with no distinct inner and outer sides. Other related non orientable objects include the Möbius strip and the real projective… …
63Transversality — in mathematics is a notion that describes how spaces can intersect; transversality can be seen as the opposite of tangency, and plays a role in general position. It formalizes the idea of a generic intersection in differential topology. It is… …
64Geometry — (Greek γεωμετρία ; geo = earth, metria = measure) is a part of mathematics concerned with questions of size, shape, and relative position of figures and with properties of space. Geometry is one of the oldest sciences. Initially a body of… …
65Mundell–Fleming model — The Mundell–Fleming model, also known as the IS LM BP model, is an economic model first set forth (independently) by Robert Mundell and Marcus Fleming.[1][2] The model is an extension of the IS LM model. Whereas the traditional IS LM Model deals… …
66Stress (physics) — Stress is a measure of the average amount of force exerted per unit area. It is a measure of the intensity of the total internal forces acting within a body across imaginary internal surfaces, as a reaction to external applied forces and body… …
67Centripetal force — Not to be confused with Centrifugal force. Classical mechanics Newton s Second Law …
68Surface normal — Normal vector redirects here. For a normalized vector, or vector of length one, see unit vector. A polygon and two of its normal vectors …
69Helix — This article is about the shape. For other uses, see Helix (disambiguation). The helix (cos t, sin t, t) from t = 0 to 4π with arrowheads showing direction of increasing t …
70Homotopy — This article is about topology. For chemistry, see Homotopic groups. The two dashed paths shown above are homotopic relative to their endpoints. The animation represents one possible homotopy. In topology, two continuous functions from one… …
