  2. Causality (physics) - Wikipedia

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

    Causality is the relationship between causes and effects. [1] [2] While causality is also a topic studied from the perspectives of philosophy and physics, it is operationalized so that causes of an event must be in the past light cone of the event and ultimately reducible to fundamental interactions. Similarly, a cause cannot have an effect ...

  3. Causal analysis - Wikipedia

    en.wikipedia.org/wiki/Causal_analysis

    Causal analysis is the field of experimental design and statistics pertaining to establishing cause and effect. [1] Typically it involves establishing four elements: correlation, sequence in time (that is, causes must occur before their proposed effect), a plausible physical or information-theoretical mechanism for an observed effect to follow from a possible cause, and eliminating the ...

  4. Causality - Wikipedia

    en.wikipedia.org/wiki/Causality

    Causality is an influence by which one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is at least partly responsible for the effect, and the effect is at least partly dependent on the cause. [1]

  5. Causal notation - Wikipedia

    en.wikipedia.org/wiki/Causal_notation

    In nature and human societies, many phenomena have causal relationships where one phenomenon A (a cause) impacts another phenomenon B (an effect). Establishing causal relationships is the aim of many scientific studies across fields ranging from biology [1] and physics [2] to social sciences and economics. [3]

  6. Causal system - Wikipedia

    en.wikipedia.org/wiki/Causal_system

    The idea that the output of a function at any time depends only on past and present values of input is defined by the property commonly referred to as causality. A system that has some dependence on input values from the future (in addition to possible dependence on past or current input values) is termed a non-causal or acausal system , and a ...

  7. Retrocausality - Wikipedia

    en.wikipedia.org/wiki/Retrocausality

    Retrocausality, or backwards causation, is a concept of cause and effect in which an effect precedes its cause in time and so a later event affects an earlier one. [ 1 ] [ 2 ] In quantum physics , the distinction between cause and effect is not made at the most fundamental level and so time-symmetric systems can be viewed as causal or retrocausal.

  8. Potentiality and actuality - Wikipedia

    en.wikipedia.org/wiki/Potentiality_and_actuality

    In philosophy, potentiality and actuality [1] are a pair of closely connected principles which Aristotle used to analyze motion, causality, ethics, and physiology in his Physics, Metaphysics, Nicomachean Ethics, and De Anima. [2] The concept of potentiality, in this context, generally refers to any "possibility" that a thing can be said to have.

  9. Causal sets - Wikipedia

    en.wikipedia.org/wiki/Causal_sets

    Although this definition uses the reflexive convention we could have chosen the irreflexive convention in which the order relation is irreflexive and asymmetric. The causal relation of a Lorentzian manifold (without closed causal curves) satisfies the first three conditions. It is the local finiteness condition that introduces spacetime ...
