  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.

  3. Constant conjunction - Wikipedia

    en.wikipedia.org/wiki/Constant_conjunction

    The philosopher David Hume used the phrase frequently in his discussion of the limits of empiricism to explain our ideas of causation and inference.In An Enquiry concerning Human Understanding and A Treatise of Human Nature, Hume proposed that the origin of our knowledge of necessary connections arises out of observation of the constant conjunction of certain impressions across many instances ...

  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. Happened-before - Wikipedia

    en.wikipedia.org/wiki/Happened-before

    This means that for any two events ,, if happened before then cannot have happened before . Let us observe that the asymmetry property directly follows from the previous properties: by contradiction, let us suppose that ∀ a , b , {\displaystyle \forall a,b,} we have a → b {\displaystyle a\to b\;} and b → a {\displaystyle b\to a} .

  6. Conditional dependence - Wikipedia

    en.wikipedia.org/wiki/Conditional_Dependence

    In essence probability is influenced by a person's information about the possible occurrence of an event. For example, let the event be 'I have a new phone'; event be 'I have a new watch'; and event be 'I am happy'; and suppose that having either a new phone or a new watch increases the probability of my being happy.

  7. Event (relativity) - Wikipedia

    en.wikipedia.org/wiki/Event_(relativity)

    One of the goals of relativity is to specify the possibility of one event influencing another. This is done by means of the metric tensor, which allows for determining the causal structure of spacetime. The difference (or interval) between two events can be classified into spacelike, lightlike and timelike separations. Only if two events are ...

  8. Independence (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Independence_(probability...

    Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes.Two events are independent, statistically independent, or stochastically independent [1] if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect the odds.

  9. Event (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Event_(probability_theory)

    In probability theory, an event is a subset of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. [1] A single outcome may be an element of many different events, [2] and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. [3]
