Anomalous perturbations are divided into two categories based on the magnitude of its effects, Macro-AP and Micro-AP.

** Anomalous dynamics ( Random walk # Anomalous diffusion ), the stochastic motion of objects with mean squared displacement ( MSD ) that deviates from the relation for normal dynamics, MSD ~ t, where t is the time the process is seen ; anomalous dynamics are either faster than normal dynamics ( MSD > t ) or slower ( MSD < t )

Anomalous dispersion can also be used to produce group and phase velocities that are in different directions.

Among these are the Koestler Parapsychology Unit at the University of Edinburgh ; the Parapsychology Research Group at Liverpool Hope University ( this closed in April 2011 ); the SOPHIA Project at the University of Arizona ; the Consciousness and Transpersonal Psychology Research Unit of Liverpool John Moores University ; the Center for the Study of Anomalous Psychological Processes at the University of Northampton ; and the Anomalistic Psychology Research Unit at Goldsmiths, University of London.

* Anomalous increase of the astronomical unit: Recent measurements indicate that planetary orbits are widening faster than if this were solely through the sun losing mass by radiating energy.

Cepheid variables are divided into several subclasses which exhibit markedly different masses, ages, and evolutionary histories: Classical Cepheids, Type II Cepheids, Anomalous Cepheids, and Dwarf Cepheids.

Anomalous propagation ( shorten as Anoprop ) includes different forms of electromagnetic ( EM ) wave propagation that are not encountered in a standard atmosphere due to a non standard distribution of temperature and humidity with height in the atmosphere.

Anomalous planes are planes which do not fit into other categories.

Anomalous X-ray Pulsars ( AXPs ) are now widely believed to be magnetars — young, isolated, highly magnetized neutron stars.

Anomalous theories have been studied in great detail and are often founded on the celebrated Atiyah – Singer index theorem or variations thereof ( see, for example, the chiral anomaly ).

Anomalous Propagation is different from ground clutter, ocean reflections ( sea clutter ), biological returns from birds and insects, debris, chaff, sand storms, volcanic eruption plumes, and other non-precipitation meteorological phenomena.

Clutter may also originate from multipath echoes from valid targets caused by ground reflection, atmospheric ducting or ionospheric reflection / refraction ( e. g. Anomalous propagation ).

On the other hand, Anomalous Diffraction Theory applies to optically soft but larger particles.

" Anomalous diffusion " commonly refers only to this very generic model, and not the many other possibilities that might be described as anomalous.

Anomalous operation, also known as anomalous perturbation, is any paranormal phenomena in which it is said that an individual ( a ) uses Psi ( parapsychology ) to influence a physical event, or ( b ) to effect a physical change, in object.

An example of Anomalous operation would be the use of Psi to manipulate a random number generator into giving out pre-selected results, or causing a compass needle to change its heading.

Anomalous dispersion happens in areas of rapid spectral variation with respect to the refractive index.

Anomalous dispersion plays a fundamental role in achieving backward propagating and superluminal light.

He was, for the final years of his life, president of the Association for the Scientific Study of Anomalous Phenomena.

* Anomalous X-ray scattering ( MAD or SAD phasing ) – the X-ray wavelength may be scanned past an absorption edge of an atom, which changes the scattering in a known way.

Anomalous compared with the three distinctions already made is the small region of the Oltrepò Pavese, formed by the Apennine foothills beyond the Po River.

Davidson, for example, subscribes to Anomalous Monism, according to which there can be no strict psycho-physical laws which connect mental and physical events under their descriptions as mental and physical events.

Anomalous propagation can be a limiting factor for the propagation of radiowaves, especially the super refraction.

Anomalous Propagation ( AP ) refers to false radar echoes usually observed when calm, stable atmospheric conditions, often associated with super refraction in a temperature inversion, direct the radar beam toward the ground.

From 1984 – 1986, Kazuma Yamane studied the development of cute handwriting, which he called Anomalous Female Teenage Handwriting, in depth.

In 2011, Bem published the article " Feeling the Future: Experimental Evidence for Anomalous Retroactive Influences on Cognition and Affect " in the Journal of Personality and Social Psychology that offered statistical evidence for psi.

* Nocturnal Lights ( NL ): Anomalous lights seen in the night sky.

They also may have relatively large amounts of trace elements that are associated with meteorites, such as nickel, platinum, iridium, and cobalt.

Two examples are kamacite and taenite, which are found in iron meteorites ; these species differ by the amount of Ni in the alloy ; kamacite has less than 5 – 7 % nickel and it's a variety of native iron, whereas the nickel content of taenite ranges from 7 – 37 %.

Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids.

All other meteorites are known as finds.

Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals ; iron meteorites are largely composed of metallic iron-nickel ; and, stony-iron meteorites contain large amounts of both metallic and rocky material.

However, an estimated 500 meteorites ranging in size from marbles to basketballs or larger do reach the surface each year ; only 5 or 6 of these are typically recovered and made known to scientists.

Few meteorites are large enough to create large impact craters.

Examples of craters caused by iron meteoroids include Barringer Meteor Crater, Odessa Meteor Crater, Wabar craters, and Wolfe Creek crater ; iron meteorites are found in association with all of these craters.

Such events are generally so energetic that the impactor is completely destroyed, leaving no meteorites.

On stony meteorites, the heat-affected zone is at most a few mm deep ; in iron meteorites, which are more thermally conductive, the structure of the metal may be affected by heat up to 1 cm below the surface.

In most cases, the largest meteorites in a shower are found farthest down-range in the strewn field.

Most meteorites are stony meteorites, classed as chondrites and achondrites.

Only 6 % of meteorites are iron meteorites or a blend of rock and metal, the stony-iron meteorites.

About 86 % of the meteorites that fall on Earth are chondrites, which are named for the small, round particles they contain.
