In the natural sciences, especially in atmospheric and Earth sciences involving applied statistics, an anomaly is a persisting deviation in a physical quantity from its expected value, e.g., the systematic difference between a measurement and a trend or a model prediction. [1]
A global anomaly is the quantum violation of a global symmetry current conservation. A global anomaly can also mean that a non-perturbative global anomaly cannot be captured by one loop or any loop perturbative Feynman diagram calculations—examples include the Witten anomaly and Wang–Wen–Witten anomaly.
In astronomy, an anomaly of an elliptical orbit, generally measured with respect to an apsis, usually the periapsis Anomalous precession , another term for "apsidal precession" Eccentric anomaly , an intermediate value used to compute the position of a celestial object as a function of time
Only if an anomaly or series of anomalies resists successful deciphering long enough and for enough members of the scientific community will the paradigm itself gradually come under challenge during what Kuhn deems a crisis of normal science. [12] If the paradigm is unsalvageable, it will be subjected to a paradigm shift. [13]
In physics, quantum mechanics, and quantum field theory, an anomaly is a breaking of a symmetry which exists at the classical level. Anomalous global symmetries are often consistent, but anomalous gauge symmetries are usually inconsistent.

Such examples may arouse suspicions of being generated by a different mechanism, [2] or appear inconsistent with the remainder of that set of data. [3] Anomaly detection finds application in many domains including cybersecurity, medicine, machine vision, statistics, neuroscience, law enforcement and financial fraud to name only a few. Anomalies ...
where M 0 is the mean anomaly at the epoch t 0, which may or may not coincide with τ, the time of pericenter passage. The classical method of finding the position of an object in an elliptical orbit from a set of orbital elements is to calculate the mean anomaly by this equation, and then to solve Kepler's equation for the eccentric anomaly.
