Curvature in physics
Did you know?
A closely related notion of curvature comes from gauge theory in physics, where the curvature represents a field and a vector potential for the field is a quantity that is in general path-dependent: it may change if an observer moves around a loop. Two more generalizations of curvature are the scalar curvature and … See more In mathematics, curvature is any of several strongly related concepts in geometry. Intuitively, the curvature is the amount by which a curve deviates from being a straight line, or a surface deviates from being a plane See more In Tractatus de configurationibus qualitatum et motuum, the 14th-century philosopher and mathematician Nicole Oresme introduces … See more As in the case of curves in two dimensions, the curvature of a regular space curve C in three dimensions (and higher) is the … See more By extension of the former argument, a space of three or more dimensions can be intrinsically curved. The curvature is intrinsic in the sense that it is a property defined at every point in the space, rather than a property defined with respect to a larger space that … See more Intuitively, the curvature describes for any part of a curve how much the curve direction changes over a small distance travelled (e.g. angle … See more The curvature of curves drawn on a surface is the main tool for the defining and studying the curvature of the surface. Curves on surfaces For a curve drawn on a surface (embedded in three-dimensional Euclidean space), … See more The mathematical notion of curvature is also defined in much more general contexts. Many of these generalizations emphasize different aspects of the curvature as it is … See more WebThe annexins are a family of Ca 2+-dependent peripheral membrane proteins.Several annexins are implicated in plasma membrane repair and are overexpressed in cancer cells. Annexin A4 (ANXA4) and Annexin A5 (ANXA5) form trimers that induce high curvature on a membrane surface, a phenomenon deemed to accelerate membrane repair.
