It is a result of studies of linear algebra and the solutions of systems of linear equat... |
Wikipedia:Spherical basis#0 | In pure and applied mathematics, particularly quantum mechanics and computer graphics and their applications, a spherical basis is the basis used to express spherical tensors. The spherical basis closely relates to the description of angular momentum in quantum mechanics and spherical harmonic functions. While spherica... |
Wikipedia:Spherical geometry#0 | Spherical geometry or spherics (from Ancient Greek σφαιρικά) is the geometry of the two-dimensional surface of a sphere or the n-dimensional surface of higher dimensional spheres. Long studied for its practical applications to astronomy, navigation, and geodesy, spherical geometry and the metrical tools of spherical tr... |
Wikipedia:Spherically complete field#0 | In mathematics, a field K with an absolute value is called spherically complete if the intersection of every decreasing sequence of balls (in the sense of the metric induced by the absolute value) is nonempty: B 1 ⊇ B 2 ⊇ ⋯ ⇒ ⋂ n ∈ N B n ≠ ∅ . {\displaystyle B_{1}\supseteq B_{2}\supseteq \cdots \Rightarrow \bigcap _{n\... |
Wikipedia:Spherics#0 | The Spherics (Greek: τὰ σφαιρικά, tà sphairiká) is a three-volume treatise on spherical geometry written by the Hellenistic mathematician Theodosius of Bithynia in the 2nd or 1st century BC. Book I and the first half of Book II establish basic geometric constructions needed for spherical geometry using the tools of Euc... |
Wikipedia:Spherics (Menelaus)#0 | The Spherics (Greek: τὰ σφαιρικά, tà sphairiká) is a three-volume treatise on spherical geometry written by the Hellenistic mathematician Theodosius of Bithynia in the 2nd or 1st century BC. Book I and the first half of Book II establish basic geometric constructions needed for spherical geometry using the tools of Euc... |
Wikipedia:Sphuṭacandrāpti#0 | Sphuṭacandrāpti (Computation of True Moon) is a treatise in Sanskrit composed by the fourteenth-century CE Kerala astronomer-mathematician Sangamagrama Madhava. The treatise enunciates a method for the computation of the position of the moon at intervals of 40 minutes each throughout the day. This is one of only two wo... |
Wikipedia:Spillover (experiment)#0 | In experiments, a spillover is an indirect effect on a subject not directly treated by the experiment. These effects are useful for policy analysis but complicate the statistical analysis of experiments. Analysis of spillover effects involves relaxing the non-interference assumption, or SUTVA (Stable Unit Treatment Val... |
Wikipedia:Spinors in three dimensions#0 | In mathematics, the spinor concept as specialised to three dimensions can be treated by means of the traditional notions of dot product and cross product. This is part of the detailed algebraic discussion of the rotation group SO(3). == Formulation == The association of a spinor with a 2×2 complex traceless Hermitian m... |
Wikipedia:Spiral of Theodorus#0 | In geometry, the spiral of Theodorus (also called the square root spiral, Pythagorean spiral, or Pythagoras's snail) is a spiral composed of right triangles, placed edge-to-edge. It was named after Theodorus of Cyrene. == Construction == The spiral is started with an isosceles right triangle, with each leg having unit ... |
