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.
Plene scriptum. In orthography, a plene scriptum (Latin for 'fully written') is a word containing an additional letter, usually one which is superfluous – not normally written in that word – nor needed for the proper comprehension of the word. Today, the term applies mostly to sacred scripture.
Polydactyly. Polydactyly or polydactylism (from Greek πολύς (polys) 'many' and δάκτυλος (daktylos) 'finger'), [1] also known as hyperdactyly, is an anomaly in humans and non-human animals resulting in supernumerary fingers and/or toes. [2] Polydactyly is the opposite of oligodactyly (fewer fingers or toes).
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 ...
Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, [9] is a congenital heart defect characterized by four specific cardiac defects. [4] Classically, the four defects are: [4] pulmonary stenosis, which is narrowing of the exit from the right ventricle; a ventricular septal defect, which is a hole allowing blood to flow between ...
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 ...
Congenital heart defect. A congenital heart defect (CHD), also known as a congenital heart anomaly, congenital cardiovascular malformation, and congenital heart disease, is a defect in the structure of the heart or great vessels that is present at birth. [ 7 ] A congenital heart defect is classed as a cardiovascular disease. [ 10 ]
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 ...
