In physics, an anomaly is a classical symmetry — a symmetry of the Lagrangian — that is broken in quantum field theories. Any anomaly can be considered to be a short-distance effect (an ultraviolet effect, in the language of quantum field theory), since it arises during the process of renormalization, when some divergent integrals cannot be regularized in such a way that all the symmetries are preserved simultaneously. However, their effects are often felt at long distances (i.e., by the infra-red physics, in the language o ...

In physics, a physical body is an object which can be described by the theories of classical mechanics, or quantum mechanics, and experimented upon by physical instruments. This includes the determination of position, and in some cases the orientation in space, as well as means to change these, by exerting forces. For instance, the force of gravity will accelerate a body if it is not supported, thus causing ...

The Chelsea Physic Garden ('physic' in the former sense of 'the science of healing'), established by the Worshipful Society of Apothecaries of London, is one of the oldest botanical gardens in Europe (second oldest in Britain), and its rock garden is the oldest English garden devoted to alpine plants. The largest fruiting olive tree in Britain is there, protected by the garden's heat-trapping high brick walls, along with what is doubtless the world's northernmost grapefruit growing outdoors. Jealously guarded during the tenure of the Society, in 1983 the Garden became a registered char ...

For the computer science term, see Action at a distance (computer science). In physics, action at a distance is the interaction of two objects which are separated in space with no known mediator of the interaction. This term was used most often with early theories of gravity and electromagnetism to describe how an object could "know" the mass (in the case o ...

Accelerator physics deals with the problems of building and operating particle accelerators. The experiments conducted with particle accelerators are not regarded as part of accelerator physics. These belong (according to the objectives of the experiments) to particle physics, nuclear physics, condensed matter physics, materials physics, etc. as well as to other sciences and technical fields. The types of experiments done at a particular accelerator and/or its other uses are largely constrained by the characteristics of the accelerator itself, such as energy (per particl ...

Atomic physics (or atom physics) is the field of physics that studies the electron hull of atoms. Lay people often associate the term atomic physics with nuclear power and nuclear bombs, obviously due to the synonymous use of atomic and nuclear in standard English. However, physicists distinguish between atomic physics (dealing with the effects of the electron hull and the nucleus's overall spin and electric charge) and nuclear physics (dealing with the forces within the atomic ...

Atomic, molecular, and optical physics is the study of matter-matter and light-matter interactions on the scale of single atoms or structures containing a few atoms. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of the energy scales that are relevant. Physicists sometimes abbreviate the field as AMO physics. All three areas include both classical and quantum treatments. Atomic molecular and optical physics - Atomic physics. ...

Please remove this notice after the article has been expanded. Details are on this talk page or at Wikipedia:Requests for expansion. A physical phenomenon is a phenomenon that is describable by physics and involved with some form of matter, energy, or spacetime. Physical phenomena are usually regarded as, at least in theory, subjects of observation - Niels Bohr, one of the fathers of quantum mechanics, is quoted with saying the "no pheno ...

Main article: Unsolved problems in physics. Research in physics is progressing constantly on a large number of fronts, and is likely to do so for the foreseeable future. In condensed matter physics, the biggest unsolved theoretical problem is the explanation for high-temperature superconductivity. Strong efforts, largely experimental, are being put into making workable spintronics and quantum computers. In particle physics, the first pieces of experimental evidence for physics beyond the Standard Model have begun ...

Main article: History of physics. See also Famous physicists and Nobel Prize in Physics. Since antiquity, people have tried to understand the behavior of matter: why unsupported objects drop to the ground, why different materials have different properties, and so forth. Also a mystery was the character of the universe, such as the form of the Earth and the behavior of celestial objects such as the Sun and the Moon. Several theories were proposed, most of which were wrong. These theories were largely couched in philosophical ter ...

Throughout the development of particle physics, there have been many objections to the extreme reductionist (or greedy reductionist) approach of attempting to explain everything in terms of elementary particles and their interaction. These objections have been raised by people from a wide array of fields, including many modern particle physicists, solid state physicists, chemists, biologists, and metaphysical holists. While the Standard Model itself is not challenged, it is contended that the properties of elementary particles ...

Physical, Physicalization The physical plane of matter is that one of the many planes in universal nature which is coordinated with our physical senses; and the physical plane of consciousness is therefore the plane on which our consciousness functions when we are using those senses.

It is characterized by the familiar qualities which science studies under the name of properties of matter. In order to understand biological evolution, it is necessary to admit the existence of the next plane above -- the astral plane. The passage of the astral prototypes of organisms from the astral plane to the physical is called physicalization. Differentiation on the physical plane is caused by the psychological and astral life-agents acting in the protyle of the physical plane. Temporary and abnormal physicalization takes place in a spiritualistic materialization.

The quaternary is said, in the Pythagorean numerical system, to be the ideal root of all numbers and things on the physical plane, because the quaternary is projected downwards, so to speak.

Physical dependence describes increased tolerance of a drug combined with a physical need of the drug to function. Abrupt cessation of the drug is typically associated with negative physical withdrawal symptoms. Physical dependence is distinguished from addiction. While addiction tends to describe psychological and behavioral attributes, physical dependence is defined primarily using physical and biological concepts. ...

Sexual touching,, also called "heavy petting", involves touching or carressing of a person's intimate parts. Examples of sexual touching include sensual massage, feeling and kissing a woman's breasts and mutual masturbation. Sexual intercourse is generally considered the ultimate form of physical intimacy.

The complexity of a physical system is equal to the probability of its being in a particular state vector. If one considers a classical Newtonian ball situation with a number of perfectly moving physical bodies bouncing off the walls of a container, the system-state probability does not change over time. The entropy of the system changes over time, but the probability of the state vector does not change. One can periodically evaluate the complexity ...

Particle physicists internationally agree on the most important goals of particle physics research in the near and intermediate future. The overarching goal, which is pursued in several distinct ways, is to find and understand what physics may lie beyond the standard model. There are several powerful experimental reasons to expect new physics, including dark matter and neutrino mass. There are also theoretical hints that this new physics should be found at accessible energy scales. Most importantly, though, there may be unexpected and unpredicted surpr ...

The term 'mathematical' physics is also sometimes used in a special sense, to distinguish research aimed at studying and solving problems inspired by physics within a mathematically rigorous framework. Mathematical physics in this sense covers a very broad area of topics with the common feature that they blend pure mathematics and physics. Although related to theoretical physics, 'mathematical' physics in this sense emphasizes the mathematical rigour of the same type as found in mathematics while theoretical physics emphasizes ...
