Anomaly (physics), a failure of a symmetry of a theory's classical action. Conformal anomaly, a quantum phenomenon that breaks the conformal symmetry of the classical theory. Chiral anomaly, an anomalous nonconservation of a chiral current. Gauge anomaly, the effect of quantum mechanics that invalidates the gauge symmetry of a quantum field theory.
Anomalistics is the use of scientific methods to evaluate anomalies (phenomena that fall outside current understanding), with the aim of finding a rational explanation. [1] The term itself was coined in 1973 by Drew University anthropologist Roger W. Wescott, who defined it as being the "serious and systematic study of all phenomena that fail ...
Abnormality (or dysfunctional behavior) is a behavioral characteristic assigned to those with conditions that are regarded as rare or dysfunctional. [1][2] Behavior is considered to be abnormal when it is atypical or out of the ordinary, consists of undesirable behavior, and results in impairment in the individual's functioning. [3] As applied ...
v. t. e. In data analysis, anomaly detection (also referred to as outlier detection and sometimes as novelty detection) is generally understood to be the identification of rare items, events or observations which deviate significantly from the majority of the data and do not conform to a well defined notion of normal behavior.

The Medieval Warm Period (MWP), also known as the Medieval Climate Optimum or the Medieval Climatic Anomaly, was a time of warm climate in the North Atlantic region that lasted from c. 950 to c. 1250. [2] Climate proxy records show peak warmth occurred at different times for different regions, which indicate that the MWP was not a globally ...
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] Similarly, a standardized anomaly equals an anomaly divided by a ...
Cerebral palsy. Cerebral palsy (CP) is a group of movement disorders that appear in early childhood. [1] Signs and symptoms vary among people and over time, [1][3] but include poor coordination, stiff muscles, weak muscles, and tremors. [1] There may be problems with sensation, vision, hearing, and speech. [1]
A congenital physical anomaly is an abnormality of the structure of a body part. It may or may not be perceived as a problem condition. It may or may not be perceived as a problem condition. Many, if not most, people have one or more minor physical anomalies if examined carefully.
