  2. Mathematical formulation of quantum mechanics - Wikipedia

    en.wikipedia.org/wiki/Mathematical_formulation...

    The phenomenology of quantum physics arose roughly between 1895 and 1915, and for the 10 to 15 years before the development of quantum mechanics (around 1925) physicists continued to think of quantum theory within the confines of what is now called classical physics, and in particular within the same mathematical structures.

    One particle: N particles: One dimension ^ = ^ + = + ^ = = ^ + (,,) = = + (,,) where the position of particle n is x n. = + = = +. (,) = /.There is a further restriction — the solution must not grow at infinity, so that it has either a finite L 2-norm (if it is a bound state) or a slowly diverging norm (if it is part of a continuum): [1] ‖ ‖ = | |.

    en.wikipedia.org/wiki/Past_paper

    A past paper is an examination paper from a previous year or previous years, usually used either for exam practice or for tests such as University of Oxford, [1] [2] University of Cambridge [3] College Collections. Exam candidates find past papers valuable in test preparation.

  5. Mathematical formulation of the Standard Model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_formulation...

    This article describes the mathematics of the Standard Model of particle physics, a gauge quantum field theory containing the internal symmetries of the unitary product group SU(3) × SU(2) × U(1). The theory is commonly viewed as describing the fundamental set of particles – the leptons, quarks, gauge bosons and the Higgs boson.

  6. Actuator - Wikipedia

    en.wikipedia.org/wiki/Actuator

    An actuator can be just a mechanism that is directly driven by the motions or forces of other parts of the system. An example is the camshafts that drive the intake and exhaust valves in internal combustion engines, driven by the engine itself.

  7. Perturbation theory (quantum mechanics) - Wikipedia

    en.wikipedia.org/wiki/Perturbation_theory...

    In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a mathematical solution is known, and add an additional "perturbing" Hamiltonian representing a weak ...

    Known in Ghana as the Maths Queen, Dr Angela Tabiri is the first African to win The Big Internet Math Off competition - quite an achievement for someone who had not initially planned to study ...

  9. Hugh Everett III - Wikipedia

    en.wikipedia.org/wiki/Hugh_Everett_III

    Hugh Everett III (/ ˈ ɛ v ər ɪ t /; November 11, 1930 – July 19, 1982) was an American physicist who, in his 1957 PhD thesis, proposed relative state interpretation of quantum mechanics. This influential approach later became the basis of the many-worlds interpretation (MWI).
