    8½ (Italian: Otto e mezzo) is a 1963 comedy drama film co-written and directed by Federico Fellini. The metafictional narrative centers on Guido Anselmi (Marcello Mastroianni), a famous Italian film director who suffers from stifled creativity as he attempts to direct an epic science fiction film. Claudia Cardinale, Anouk Aimée, Sandra Milo ...

    en.wikipedia.org/wiki/Runge–Kutta_methods

    t. e. In numerical analysis, the Runge–Kutta methods (English: / ˈrʊŋəˈkʊtɑː / ⓘ RUUNG-ə-KUUT-tah[1]) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. [2]

  4. Stationary phase approximation - Wikipedia

    en.wikipedia.org/wiki/Stationary_phase_approximation

    In mathematics, the stationary phase approximation is a basic principle of asymptotic analysis, applying to functions given by integration against a rapidly-varying complex exponential. This method originates from the 19th century, and is due to George Gabriel Stokes and Lord Kelvin. [1] It is closely related to Laplace's method and the method ...

    [1] [2] This scale is more widely used in the United States [3] than other similar and more descriptive [4] [5] scales such as the Zadoks scale or the BBCH scale. Like other scales of crop development, the Feekes scale is useful in planning management strategies that incorporate plant growth information for the use of pesticides and fertilizers ...

    en.wikipedia.org/wiki/Lax–Wendroff_method

    What follows is the Richtmyer two-step Lax–Wendroff method. The first step in the Richtmyer two-step Lax–Wendroff method calculates values for f(u(x, t)) at half time steps, t n + 1/2 and half grid points, x i + 1/2. In the second step values at t n + 1 are calculated using the data for t n and t n + 1/2.

  8. Duplicate bridge movements - Wikipedia

    en.wikipedia.org/wiki/Duplicate_bridge_movements

    There are several considerations in determining the fairness of a bridge movement. A complete movement, in which each entrant plays against all of the other entrants or in which all entrants in each scoring field play against all of the same field of opponents, is inherently the fairest choice. The worst scenario is a movement that is one round short of complete: one entrant does not play ...

  9. Spin (physics) - Wikipedia

    en.wikipedia.org/wiki/Spin_(physics)

    Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2]: 183–184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory.
