91Hypernombre — Les hypernombres sont des nombres associés à des dimensions, découverts par le Dr. Charles A. Musès (1919 – 2000). Les hypernombres forment un système complet, cohérent, relié et naturel. Il existe dix niveaux d hypernombres, chacun possède sa… …
92Кватернионы и вращение пространства — Эта статья или раздел нуждается в переработке. Пожалуйста, улучшите статью в соответствии с правилами написания статей …
93Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… …
94Klein quartic — In hyperbolic geometry, the Klein quartic, named after Felix Klein, is a compact Riemann surface of genus 3 with the highest possible order automorphism group for this genus, namely order 168. As such, the Klein quartic is the Hurwitz surface of… …
95Holonomy — Parallel transport on a sphere depends on the path. Transporting from A → N → B → A yields a vector different from the initial vector. This failure to return to the initial vector is measured by the holonomy of the connection. In differential… …
96Polar decomposition — In mathematics, particularly in linear algebra and functional analysis, the polar decomposition of a matrix or linear operator is a factorization analogous to the polar form of a nonzero complex number z where r is the absolute value of z (a… …
97Root mean square deviation (bioinformatics) — The root mean square deviation (RMSD) is the measure of the average distance between the backbones of superimposed proteins. In the study of globular protein conformations, one customarily measures the similarity in three dimensional structure by …
98Binary tetrahedral group — In mathematics, the binary tetrahedral group is an extension of the tetrahedral group T of order 12 by a cyclic group of order 2.It is the binary polyhedral group corresponding to the tetrahedral group, and as such can be defined as the preimage… …
99Binary octahedral group — In mathematics, the binary octahedral group is an extension of the octahedral group O of order 24 by a cyclic group of order 2. It can be defined as the preimage of the octahedral group under the 2:1 covering homomorphism:mathrm{Sp}(1) o… …
100Biquaternion — Die Biquaternionen sind ein hyperkomplexes Zahlensystem, das von William Kingdon Clifford in der zweiten Hälfte des 19. Jahrhunderts beschrieben wurde. Vor Clifford hatte Arthur Cayley bereits die Quaternionen mit komplexen Koeffizienten (also… …
