  2. Quantum mechanics - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics

    Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.

  3. Quantum - Wikipedia

    en.wikipedia.org/wiki/Quantum

    The word quantum is the neuter singular of the Latin interrogative adjective quantus, meaning "how much"."Quanta", the neuter plural, short for "quanta of electricity" (electrons), was used in a 1902 article on the photoelectric effect by Philipp Lenard, who credited Hermann von Helmholtz for using the word in the area of electricity.

    "Conundrum" (song), an instrumental song by Jethro Tull on their album Bursting Out "Conundrum" (), the two-hour series finale of primetime soap opera Dallas"Conundrum" (Star Trek: The Next Generation), a 1992 fifth-season episode of Star Trek: The Next Generation

  5. Quantum mechanics of time travel - Wikipedia

    en.wikipedia.org/wiki/Quantum_mechanics_of_time...

    The theoretical study of time travel generally follows the laws of general relativity. Quantum mechanics requires physicists to solve equations describing how probabilities behave along closed timelike curves (CTCs), which are theoretical loops in spacetime that might make it possible to travel through time.

    Quantum Conundrum is a puzzle-platform game developed by Airtight Games and published by Square Enix. [3] It was directed by Portal lead designer Kim Swift.The game was released for Microsoft Windows via Steam in June 2012, and for PlayStation 3 via PlayStation Network, and Xbox 360 via Xbox Live Arcade in July 2012.

  7. Problem of time - Wikipedia

    en.wikipedia.org/wiki/Problem_of_time

    In classical mechanics, a special status is assigned to time in the sense that it is treated as a classical background parameter, external to the system itself.This special role is seen in the standard Copenhagen interpretation of quantum mechanics: all measurements of observables are made at certain instants of time and probabilities are only assigned to such measurements.

  8. Quorum call - Wikipedia

    en.wikipedia.org/wiki/Quorum_call

    In legislatures, a quorum call is used to determine whether a quorum is present. Since attendance at debates is not mandatory in most legislatures, it is often the case that a quorum of members is not present while the debate is ongoing.

  9. Quantum complexity theory - Wikipedia

    en.wikipedia.org/wiki/Quantum_complexity_theory

    Quantum complexity theory is the subfield of computational complexity theory that deals with complexity classes defined using quantum computers, a computational model based on quantum mechanics.
