Surface theory
In mathematics, the differential geometry of surfaces deals with the differential geometry of smooth surfaces with various additional structures, most often, a Riemannian metric. Surfaces have been extensively studied from various perspectives: extrinsically, relating to their embedding in … See more The volumes of certain quadric surfaces of revolution were calculated by Archimedes. The development of calculus in the seventeenth century provided a more systematic way of computing them. Curvature of general … See more Definition It is intuitively clear that a sphere is smooth, while a cone or a pyramid, due to their vertex or edges, are not. The notion of a "regular surface" … See more For any surface embedded in Euclidean space of dimension 3 or higher, it is possible to measure the length of a curve on the surface, the angle between two curves and the area of a region on the surface. This structure is encoded infinitesimally in a See more Once a metric is given on a surface and a base point is fixed, there is a unique geodesic connecting the base point to each sufficiently … See more It is intuitively quite familiar to say that the leaf of a plant, the surface of a glass, or the shape of a face, are curved in certain ways, and that all of … See more Surfaces of revolution A surface of revolution is obtained by rotating a curve in the xz-plane about the z-axis. Such … See more Curves on a surface which minimize length between the endpoints are called geodesics; they are the shape that an elastic band stretched between the two points would take. Mathematically they are described using ordinary differential equations and … See more WebAug 28, 2024 · The BET theory was developed by Stephen Brunauer (Figure 2.3. 1 ), Paul Emmett (Figure 2.3. 2 ), and Edward Teller (Figure 2.3. 3 ) in 1938. The first letter of each publisher’s surname was taken to name this theory. The BET theory was an extension of the Langmuir theory, developed by Irving Langmuir (Figure 2.3.
