A deviation from a rule or from what is regarded as normal; an outlier. / Something or someone that is strange or unusual.

plural of anomaly

(astronomy, celestial mechanics) The angle PCR formed by P = the periapsis of a celestial body's elliptical orbit, C = the center of that elliptical orbit, and R = the corresponding point to that celestial body (the projection of the celestial body along a direction parallel to the minor axis of its orbit onto the auxiliary circle (a circle which shares a diameter with the major axis of the celestial body's orbit)).

(astronomy, celestial mechanics) An orbital parameter of a celestial body (in an elliptic orbit); the mean motion multiplied by the time since the last passage through periapsis; the angle PCM (measured in radians) defined by P = the periapsis, C = the center of the elliptical orbit, and M = the mean planet.

(astronomy, celestial mechanics) The angle PFC formed by P = the periapsis of a celestial body's elliptical orbit, F = the focus of that orbit, and C = the current position of the celestial body.

(physics) The discrepancy between current scientific models and the actual increase in speed observed during a planetary flyby by a spacecraft.

(quantum mechanics) Any phenomenon that arises when a quantity that becomes zero according to classical physics acquires a finite value when quantum rules are utilized.

(physics) A variation in the heat capacity of a solid at low temperatures which arises from the thermal population of discrete energy levels as the temperature is raised
