91Paley construction — In mathematics, the Paley construction is a method for constructing Hadamard matrices using finite fields. The construction was described in 1933 by the English mathematician Raymond Paley.The Paley construction uses quadratic residues in a… …
92Transversal (geometry) — A transversal cutting two parallel lines In geometry, a transversal is a line that passes through two or more other lines in the same plane at different points. When the lines are parallel, as is often the case, a transversal produces several… …
93Neuro emotional technique — NET Neuro Emotional Technique (NET) is an innovative, mind body, stress reduction intervention that helps resolve dysfunctional psychophysiological states called neuro emotional complexes (NEC’s). NEC’s originate in past anxiety arousing events… …
94Circle packing in a circle — is a two dimensional packing problem with the objective of packing unit circles into the smallest possible larger circle. Minimum solutions:[1] Number of unit circles Enclosing circle radius Density Optimality Diagram 1 1 1.0000 Trivially optimal …
95CRISTAUX - Cristallographie — Le nom de cristal fut d’abord réservé aux substances minérales naturelles limitées par des formes polyédriques plus ou moins parfaites. L’existence de formes polyédriques était alors considérée comme le critère essentiel de la définition du… …
96Platonic solid — In geometry, a Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex; thus, all… …
97Mood (psychology) — A mood is a relatively long lasting emotional state. Moods differ from emotions in that they are less specific, less intense, and less likely to be triggered by a particular stimulus or event.[1] Moods generally have either a positive or negative …
98Regular polytope — In mathematics, a regular polytope is a polytope whose symmetry is transitive on its flags, thus giving it the highest degree of symmetry. All its elements or j faces (for all 0≤ j ≤ n , where n is the dimension of the polytope) cells, faces and… …
99Hausdorff paradox — In mathematics, the Hausdorff paradox, named after Felix Hausdorff, states that if you remove a certain countable subset of the sphere S ², the remainder can be divided into three subsets A , B and C such that A , B , C and B ∪ C are all… …
100Spherical trigonometry — Spherical triangle Spherical trigonometry is a branch of spherical geometry which deals with polygons (especially triangles) on the sphere and the relationships between the sides and the angles. This is of great importance for calculations in… …
