  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. Causality - Wikipedia

    en.wikipedia.org/wiki/Causality

    Causality is one of the most fundamental and essential notions of physics. [46] Causal efficacy cannot 'propagate' faster than light. Otherwise, reference coordinate systems could be constructed (using the Lorentz transform of special relativity ) in which an observer would see an effect precede its cause (i.e. the postulate of causality would ...

  4. 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 ...

  5. 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 ...

  6. 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]

  7. Causal reasoning - Wikipedia

    en.wikipedia.org/wiki/Causal_reasoning

    The study of causality extends from ancient philosophy to contemporary neuropsychology; assumptions about the nature of causality may be shown to be functions of a previous event preceding a later one. The first known protoscientific study of cause and effect occurred in Aristotle's Physics. [1] Causal inference is an example of causal reasoning.

    One experiment involving 285 birds has found 96% of them had white striping and woody breast, meaning tougher meat. And while it's found to be safe for consumption, Chipotle and Panera have now ...

  9. 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.
