Force Field (chemistry)
In the context of chemistry and molecular modelling, a force field is a computational method that is used to estimate the forces between atoms within molecules and also between molecules. More precisely, the force field refers to the functional form and parameter sets used to calculate the potential energy of a system of atoms or coarse-grained particles in molecular mechanics, molecular dynamics, or Monte Carlo simulations. The parameters for a chosen energy function may be derived from experiments in physics and chemistry, calculations in quantum mechanics, or both. Force fields are interatomic potentials and utilize the same concept as force fields in classical physics, with the difference that the force field parameters in chemistry describe the energy landscape, from which the acting forces on every particle are derived as a gradient of the potential energy with respect to the particle coordinates. ''All-atom'' force fields provide parameters for every type of ato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Field (physics)
In physics, a force field is a vector field corresponding with a non-contact force acting on a particle at various positions in space. Specifically, a force field is a vector field \vec, where \vec(\vec) is the force that a particle would feel if it were at the point \vec. Examples *Gravity is the force of attraction between two objects. A gravitational force field models this influence that a massive body (or more generally, any quantity of energy) extends into the space around itself. In Newtonian gravity, a particle of mass ''M'' creates a gravitational field \vec=\frac\hat, where the radial unit vector \hat points away from the particle. The gravitational force experienced by a particle of light mass ''m'', close to the surface of Earth is given by \vec = m \vec, where ''g'' is the standard gravity. *An electric field \vec is a vector field. It exerts a force on a point charge ''q'' given by \vec = q\vec. Work Work is dependent on the displacement as well as the for ...

Force Field (technology)
In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble or deflector shield, is a barrier made of things like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, plasma, particles, radiation, solid light, or pure force. It protects a person, area, or object from attacks or intrusions or even deflects energy attacks back at the attacker. This fictional technology is created as a field of energy without mass that acts as a wall, so that objects affected by the particular force relating to the field are unable to pass through the field and reach the other side, are deflected or destroyed. Actual research in the 21st century has looked into the potential to deflect radiation or cosmic rays, but also more extensive shielding. This concept has become a staple of many science-fiction works, so much so that authors frequently do not even bother to explain or justify th ...

Spinal Cord
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone). The backbone encloses the central canal of the spinal cord, which contains cerebrospinal fluid. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and then enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around long in adult men and around long in adult women. The diameter of the spinal cord ranges from in the cervical and lumbar regions to in the thoracic area. The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force-field Analysis
In social science, force-field analysis provides a framework for looking at the factors ("forces") that influence a situation, originally social situations. It looks at forces that are either driving movement toward a goal (helping forces) or blocking movement toward a goal (hindering forces). The principle, developed by Kurt Lewin, is a significant contribution to the fields of social science, psychology, social psychology, community psychology, communication, organizational development, process management, and change management. History Lewin, a social psychologist, believed the "field" to be a Gestalt psychological environment existing in an individual's (or in the collective group) mind at a certain point in time that can be mathematically described in a topological constellation of constructs. The "field" is very dynamic, changing with time and experience. When fully constructed, an individual's "field" (Lewin used the term "life space") describes that person's motives, value ...

Smash Mouth (album)
''Smash Mouth'' is the third studio album by American rock band Smash Mouth. It was released on November 27, 2001 by Interscope Records. It is notable in that it was their first album with new drummer Michael Urbano and its release was delayed a few months due to the death of lead vocalist Steve Harwell's son, Presley Scott Harwell. The album was eventually certified Gold by the RIAA for sales in excess of 500,000 in the U.S. Smash Mouth held a contest on their website in the fall of 2000 to name their third album. The result was a two-way tie with the winning suggestion being to self-title the album. It was released in the fall of 2001 along with the single " Pacific Coast Party". Track listing Personnel Smash Mouth *Steve Harwell – lead vocals *Paul De Lisle – bass, backing vocals *Greg Camp – guitars, backing vocals * Michael Urbano – drums, programming Touring members *Michael Klooster – keyboards *Mark Cervantes – percussion Additional personnel *Le ...

Forcefield (art Collective)
Forcefield was an American noise band and art collective, founded in 1997 in Providence, Rhode Island, closely associated with Fort Thunder.Smith, Roberta (16 December 2006).Looking for Graphic Lightning From Fort Thunder, ''The New York Times''. Retrieved 19 October 2012. Work Known for performing in colorful full-body knit-wear of their own design, the band rarely played outside of Rhode Island but did two US tours with their Fort Thunder roommates Lightning Bolt. Members included Meerk Puffy ( Matt Brinkman), Gorgon Radeo ( Jim Drain), P Lobe ( Ara Peterson), and Le Geef (Leif Goldberg). The group become more widely recognized after being included in the 2002 Whitney Biennial, but disbanded shortly afterwards.
