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 ...
v. t. e. In sociology, anomie or anomy (/ ˈænəmi /) is a social condition defined by an uprooting or breakdown of any moral values, standards or guidance for individuals to follow. [1][2] Anomie is believed to possibly evolve from conflict of belief systems [3] and causes breakdown of social bonds between an individual and the community ...
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. [1]
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 ...
Anomalistic psychology. In psychology, anomalistic psychology is the study of human behaviour and experience connected with what is often called the paranormal, with few assumptions made about the validity of the reported phenomena.
Scientists. v. t. e. In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. [1][2] In classical physics, a classical anomaly is the failure of a symmetry to be restored in the limit in which the symmetry-breaking parameter ...
Apparitional experiences. A common type of anomalous experience is the apparitional experience, which may be defined as one in which a subject seems to perceive some person or thing that is not physically present. Self-selected samples tend to report a predominance of human figures, but apparitions of animals, [5] and even objects [6] are also ...
