Classical guitar — A modern classical guitar from the front and side String instrument Hornbostel–Sachs classification 321.322 5 (Composite chordophone sounded by the bare fingers or … Wikipedia
Classical unified field theories — Since the 19th century, some physicists have attempted to develop a single theoretical framework that can account for the fundamental forces of nature – a unified field theory. Classical unified field theories are attempts to create a unified… … Wikipedia
Classical guitar technique — This article is about the Contemporary classical guitar technique. For the baroque guitar technique see Baroque guitar and for the romantique guitar technique, see Romantic guitar. The classical guitar technique is a fingerstyle technique used by … Wikipedia
Curvature invariant — In Riemannian geometry and pseudo Riemannian geometry, curvature invariants are scalar quantities constructed from tensors that represent curvature. These tensors are usually the Riemann tensor, the Weyl tensor, the Ricci tensor and tensors… … Wikipedia
Classical field theory — A classical field theory is a physical theory that describes the study of how one or more physical fields interact with matter. The word classical is used in contrast to those field theories that incorporate quantum mechanics (quantum field… … Wikipedia
Classical treatment of tensors — A tensor is a generalization of the concepts of vectors and matrices. Tensors allow one to express physical laws in a form that applies to any coordinate system. For this reason, they are used extensively in continuum mechanics and the theory of… … Wikipedia
Sectional curvature — In Riemannian geometry, the sectional curvature is one of the ways to describe the curvature of Riemannian manifolds. The sectional curvature K(σp) depends on a two dimensional plane σp in the tangent space at p. It is the Gaussian curvature of… … Wikipedia
Gaussian curvature — In differential geometry, the Gaussian curvature or Gauss curvature of a point on a surface is the product of the principal curvatures, κ 1 and κ 2, of the given point. It is an intrinsic measure of curvature, i.e., its value depends only on how… … Wikipedia
Ricci curvature — In differential geometry, the Ricci curvature tensor, named after Gregorio Ricci Curbastro, provides one way of measuring the degree to which the geometry determined by a given Riemannian metric might differ from that of ordinary Euclidean n… … Wikipedia
Membrane curvature — is the geometrical measure or characterization of the curvature of membranes. The membranes can be naturally occurring or man made (synthetic). An example of naturally occurring membrane is the lipid bilayer of cells, also known as cellular… … Wikipedia
Affine curvature — This article is about the curvature of affine plane curves, not to be confused with the curvature of an affine connection. Special affine curvature, also known as the equi affine curvature or affine curvature, is a particular type of curvature… … Wikipedia
