  2. Uncertainty principle - Wikipedia

    en.wikipedia.org/wiki/Uncertainty_principle

    The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum, can be simultaneously known. In other words, the more accurately one property is measured ...

  3. Conjugate variables - Wikipedia

    en.wikipedia.org/wiki/Conjugate_variables

    In quantum mechanics, these same pairs of variables are related by the Heisenberg uncertainty principle. The energy of a particle at a certain event is the negative of the derivative of the action along a trajectory of that particle ending at that event with respect to the time of the event.

  5. Quantum fluctuation - Wikipedia

    en.wikipedia.org/wiki/Quantum_fluctuation

    3D visualization of quantum fluctuations of the quantum chromodynamics (QCD) vacuum [1]. In quantum physics, a quantum fluctuation (also known as a vacuum state fluctuation or vacuum fluctuation) is the temporary random change in the amount of energy in a point in space, [2] as prescribed by Werner Heisenberg's uncertainty principle.

  6. Wave function collapse - Wikipedia

    en.wikipedia.org/wiki/Wave_function_collapse

    The concept of wavefunction collapse was introduced by Werner Heisenberg in his 1927 paper on the uncertainty principle, "Über den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik", and incorporated into the mathematical formulation of quantum mechanics by John von Neumann, in his 1932 treatise Mathematische Grundlagen der ...

  7. Uncertainty - Wikipedia

    en.wikipedia.org/wiki/Uncertainty

    In physics, the Heisenberg uncertainty principle forms the basis of modern quantum mechanics. [ 17 ] In metrology , measurement uncertainty is a central concept quantifying the dispersion one may reasonably attribute to a measurement result.

  8. Generalized uncertainty principle - Wikipedia

    en.wikipedia.org/wiki/Generalized_uncertainty...

    The Generalized Uncertainty Principle (GUP) represents a pivotal extension of the Heisenberg Uncertainty Principle, incorporating the effects of gravitational forces to refine the limits of measurement precision within quantum mechanics. Rooted in advanced theories of quantum gravity, including string theory and loop quantum gravity, the GUP ...

  9. Complementarity (physics) - Wikipedia

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

    In physics, complementarity is a conceptual aspect of quantum mechanics that Niels Bohr regarded as an essential feature of the theory. [1] [2] The complementarity principle holds that certain pairs of complementary properties cannot all be observed or measured simultaneously. For example, position and momentum or wave and particle properties.
