In physics, a particle is an object, or body, with only a few degrees-of-freedom, including position, and perhaps orientation in space. In physics, particularly in quantum physics a system observable is a property of the system state that can be determined by some sequence of physical operations. ... 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. ... The phrase degrees of freedom is used in three different branches of science: in physics and physical chemistry, in mechanical and aerospace engineering, and in statistics. ... The word position can have one of several meanings: 2-dimensional or 3-dimensional location; Occupation, Job In finance, a position means entitlement to receive or obligation to deliver an asset or financial instrument, as in long position (ownership) and short position (obligation to deliver); In politics and government a... Orientation can refer to different things. ... Attempting to understand the nature of space has always been a prime occupation for philosophers and scientists. ...


The homogeneity and isotropy of space, being symmetries with respect to translation and rotation, may provide for particle properties such as momentum and angular momentum. These are common to classical mechanics and quantum mechanics. Certain internal degrees-of-freedom provide fixed physical properties, such as (electric) charge, or variable ones, such as spin angular momentum, most of which can only be understood within quantum mechanics. Homogeneity in physics In physics, homogeneity is the quality of having all properties independent of the position. ... Isotropy (the opposite of anisotropy) is the property of being independent of direction. ... Symmetry is a characteristic of geometrical shapes, equations and other objects; we say that such an object is symmetric with respect to a given operation if this operation, when applied to the object, does not appear to change it. ... Translation is an activity comprising the interpretation of the meaning of a text in one language — the source text — and the production of a new, equivalent text in another language — called the target text, or the translation. ... Rotation is the movement of a body in such a way that the distance between a certain fixed point and any given point of that body remains constant. ... In physics, momentum is a physical quantity related to the velocity and mass of an object. ... In physics, angular momentum intuitively measures how much the linear momentum is directed around a certain point called the origin; the moment of momentum. ... In physics, Classical mechanics is one of the two major sub-fields of study in the science of mechanics, which is concerned with the motions of bodies, and the forces that cause them. ... Fig. ... The article on electrical energy is located elsewhere. ... Charge is a word with many different meanings. ... The terms spin and SPIN have several meanings, including those primarily discussed as spinning: For spin in sub-atomic physics, see spin (physics) For the stalled aircraft maneuver or any of several forms of loss of control in aircraft, see spin (flight) For the periodical, see Spin Magazine For the...

Particles erupt from the collision point of two relativistic (100GeV) gold ions in the STAR detector of the Relativistic Heavy Ion Collider.
Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them.
This divide of efforts in particle physics is reflected in the names of categories on the preprint archive [1]: hep-th (theory), hep-ph (phenomenology), hep-ex (experiments), hep-lat (lattice gauge theory).
