  2. Bell test - Wikipedia

    en.wikipedia.org/wiki/Bell_test

    An experiment free of the locality loophole is one where for each separate measurement and in each wing of the experiment, a new setting is chosen and the measurement completed before signals could communicate the settings from one wing of the experiment to the other. An experiment free of the detection loophole is one where close to 100% of ...

  3. Superposition principle - Wikipedia

    en.wikipedia.org/wiki/Superposition_principle

    The superposition principle, [1] also known as superposition property, states that, for all linear systems, the net response caused by two or more stimuli is the sum of the responses that would have been caused by each stimulus individually.

  4. Schrödinger's cat - Wikipedia

    en.wikipedia.org/wiki/Schrödinger's_cat

    In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is unobserved in a closed box, as a result of its fate being linked to a random subatomic event that may or may not

  6. Law of superposition - Wikipedia

    en.wikipedia.org/wiki/Law_of_superposition

    The law of superposition is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields pertaining to geological stratigraphy.In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will lie at the bottom of the sequence, while newer material stacks upon the surface to form new deposits over time.

  7. Bell's theorem - Wikipedia

    en.wikipedia.org/wiki/Bell's_theorem

    In Bell tests, there may be problems of experimental design or set-up that affect the validity of the experimental findings. These problems are often referred to as "loopholes". The purpose of the experiment is to test whether nature can be described by local hidden-variable theory, which would contradict the predictions of quantum mechanics.

  8. Measurement problem - Wikipedia

    en.wikipedia.org/wiki/Measurement_problem

    In quantum mechanics, the measurement problem is the problem of definite outcomes: quantum systems have superpositions but quantum measurements only give one definite result. [ 1 ] [ 2 ] The wave function in quantum mechanics evolves deterministically according to the Schrödinger equation as a linear superposition of different states.

  9. Coulomb's law - Wikipedia

    en.wikipedia.org/wiki/Coulomb's_law

    Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force . [ 2 ]
