  2. Solenoid (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Solenoid_(mathematics)

    The Smale-Williams solenoid. In mathematics, a solenoid is a compact connected topological space (i.e. a continuum) that may be obtained as the inverse limit of an inverse system of topological groups and continuous homomorphisms

  3. Vector space - Wikipedia

    en.wikipedia.org/wiki/Vector_space

    In mathematics and physics, a vector space (also called a linear space) is a set whose elements, often called vectors, can be added together and multiplied ("scaled") by numbers called scalars. The operations of vector addition and scalar multiplication must satisfy certain requirements, called vector axioms.

    As well as being an elegant theorem in its own right, Lagrange's four square theorem has useful applications in areas of mathematics outside number theory, such as combinatorial design theory. The quaternion-based proof uses Hurwitz quaternions , a subring of the ring of all quaternions for which there is an analog of the Euclidean algorithm .

  6. Mathematics education - Wikipedia

    en.wikipedia.org/wiki/Mathematics_education

    Discovery math: a constructivist method of teaching (discovery learning) mathematics which centres around problem-based or inquiry-based learning, with the use of open-ended questions and manipulative tools. [23] This type of mathematics education was implemented in various parts of Canada beginning in 2005. [24]

  7. Pendulum - Wikipedia

    en.wikipedia.org/wiki/Pendulum

    "Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.

    [12] [13] This was effectively the logistic equation, [14] originally derived by Pierre François Verhulst. [15] In 1920 Lotka extended the model, via Andrey Kolmogorov , to "organic systems" using a plant species and a herbivorous animal species as an example [ 16 ] and in 1925 he used the equations to analyse predator–prey interactions in ...

  9. Mathematics and art - Wikipedia

    en.wikipedia.org/wiki/Mathematics_and_art

    Mathematics and art are related in a variety of ways. Mathematics has itself been described as an art motivated by beauty. Mathematics can be discerned in arts such as music, dance, painting, architecture, sculpture, and textiles. This article focuses, however, on mathematics in the visual arts. Mathematics and art have a long historical ...
