  2. Dynamical pictures - Wikipedia

    en.wikipedia.org/wiki/Dynamical_pictures

    In quantum mechanics, dynamical pictures (or representations) are the multiple equivalent ways to mathematically formulate the dynamics of a quantum system. The two most important ones are the Heisenberg picture and the Schrödinger picture .

  3. Einstein's thought experiments - Wikipedia

    en.wikipedia.org/wiki/Einstein's_thought_experiments

    Quantum mechanics, at least in the Copenhagen interpretation, appeared to allow action at a distance, the ability for two separated objects to communicate at speeds greater than light. By 1928, the consensus was that Einstein had lost the debate, and even his closest allies during the Fifth Solvay Conference, for example Louis de Broglie ...

  4. 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. Quantum mechanics can describe many systems that classical physics cannot.

  5. Heisenberg picture - Wikipedia

    en.wikipedia.org/wiki/Heisenberg_picture

    The original Heisenberg paper translated (although difficult to read, it contains an example for the anharmonic oscillator): Sources of Quantum mechanics B.L. Van Der Waerden The computations for the hydrogen atom in the Heisenberg representation originally from a paper of Pauli [3]

  6. Bohr–Einstein debates - Wikipedia

    en.wikipedia.org/wiki/Bohr–Einstein_debates

    In many textbook examples and popular discussions of quantum mechanics, the principle of indeterminacy is explained by reference to the pair of variables position and velocity (or momentum). It is important to note that the wave nature of physical processes implies that there must exist another relation of indeterminacy: that between time and ...

  7. Thought experiment - Wikipedia

    en.wikipedia.org/wiki/Thought_experiment

    Examples of thought experiments include Schrödinger's cat, illustrating quantum indeterminacy through the manipulation of a perfectly sealed environment and a tiny bit of radioactive substance, and Maxwell's demon, which attempts to demonstrate the ability of a hypothetical finite being to violate the 2nd law of thermodynamics.

  8. Copenhagen interpretation - Wikipedia

    en.wikipedia.org/wiki/Copenhagen_interpretation

    Quantum mechanics cannot easily be reconciled with everyday language and observation, and has often seemed counter-intuitive to physicists, including its inventors. [note 1] The ideas grouped together as the Copenhagen interpretation suggest a way to think about how the mathematics of quantum theory relates to physical reality.

  9. Quantum mind - Wikipedia

    en.wikipedia.org/wiki/Quantum_mind

    The quantum mind or quantum consciousness is a group of hypotheses proposing that local physical laws and interactions from classical mechanics or connections between neurons alone cannot explain consciousness, [1] positing instead that quantum-mechanical phenomena, such as entanglement and superposition that cause nonlocalized quantum effects, interacting in smaller features of the brain than ...
