Particle physics

Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter (particles with mass) and radiation (massless particles). Although the word "particle" can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), "particle physics" usually investigates the irreducibly smallest detectable particles and the irreducibly fundamental force fields necessary to explain them. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity.

Subatomic particles

Modern particle physics research is focused on subatomic particles, including atomic constituents such as electrons, protons, and neutrons (protons and neutrons are composite particles called baryons, made of quarks), produced by radioactive and scattering processes, such as photons, neutrinos, and muons, as well as a wide range of exotic particles. Dynamics of particles is also governed by quantum mechanics; they exhibit wave–particle duality, displaying particle-like behaviour under certain experimental conditions and wave-like behaviour in others. In more technical terms, they are described by quantum state vectors in a Hilbert space, which is also treated in quantum field theory. Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles.

Energy

In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed. The "ability of a system to perform work" is a common description, but it is difficult to give one single comprehensive definition of energy because of its many forms. For instance, in SI units, energy is measured in joules, and one joule is defined "mechanically", being the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton. However, there are many other definitions of energy, depending on the context, such as thermal energy, radiant energy, electromagnetic, nuclear, etc., where definitions are derived that are the most convenient.

Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy, and obey the law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.

High energy

High energy may refer to:

  • High energy physics, a branch of physics dealing with subatomic particles and ionizing radiation
  • Hi-NRG, a kind of dance music
  • High Energy (The Supremes album), 1976
  • "High Energy" (The Supremes song), 1976
  • High Energy (Freddie Hubbard album), 1974
  • "High Energy" (Evelyn Thomas song), 1984
  • High Energy, a 1990s professional wrestling tag team consisting of Owen Hart and Koko B. Ware
  • See also

  • High Inergy
  • High Energy (The Supremes song)

    "High Energy" is a dance/disco song by The Supremes. Released as the album's title-track single in 1976 from their penultimate album High Energy, this energic, sound-bursting tune featured lead vocals by Susaye Greene. Greene, new to the group, was brought in to dub her vocals although Scherrie Payne had already recorded lead vocals prior to Greene's entry into the trio. As such, this was the final single to feature former member Cindy Birdsong's vocals, and the sixth and final single of the group to feature four members. Written by Harold Beatty, Brian Holland and Edward Holland, Jr., the song peaked at position nine on the dance/disco charts later that same year.

  • High Energy (The Supremes album)

    High Energy is the twenty-eighth studio album by The Supremes, released in 1976 on the Motown label. The first album since 1968's Reflections to include four Supremes members (not counting albums after Diana Ross was given individual billing containing outtakes from Florence Ballard's tenure in the group), it also is notable for featuring the last Billboard Hot 100 Top 40 pop hit for the group, "I'm Gonna Let My Heart Do the Walking". The album sold around 125,000 copies in the USA.

    Overview

    The penultimate studio album released by the group, the Supremes began recording High Energy in December 1975, when its lineup consisted of Scherrie Payne, Mary Wilson and Cindy Birdsong. Birdsong left the group in February 1976, and her replacement, Susaye Greene, was overdubbed on two tracks, including "I'm Gonna Let My Heart Do the Walking". Greene also assumed lead vocal duties on the title track. Along with Meet The Supremes and Reflections, these are the only studio albums to include four members of the group rather than the usual three. (Let the Sunshine In and Cream of the Crop both had Florence Ballard appear on a previously recorded track for each album, though she had long been dismissed from the group).
