... be situated at rest in S’ at some small distance from the wire. First, consider the viewpoint of the S-observer. According to all the above-mentioned authorities, the S-observer, with respect to whom the wire is at rest, judges it to be electrically neutral; so he measures zero electric field. This ...

... a. According to Newton’s first law of motion, an objects state of motion does not change as long as the net force acting on it is zero. b. Inertia is the tendency of an object in motion to slow down and come to a complete stop if it travels far enough in the same direction. 36. What is Newton’s seco ...

Mean field theory and Hartree
... Mean field theory and Hartree-Fock theory Perhaps the first mean-field theory was the alteration of the Curie law χ ∝ 1 / T for a paramagnet, to the Curie-Weiss law χ ∝ 1 / (T − Tc ) for a ferromagnet at T above the Curie temperature Tc. The derivation says that roughly speaking, a microscopic spin ...

... According to Newton's Second Law, the net force on a mass must change if its acceleration changes in either magnitude or direction. No net force means the body moves at constant velocity (which need not be zero). In this lab you will record the force on a body connected by a string over a pulley to ...

Fundamental interaction
Fundamental interactions, also known as fundamental forces, are the interactions in physical systems that don't appear to be reducible to more basic interactions. There are four conventionally accepted fundamental interactions—gravitational, electromagnetic, strong nuclear, and weak nuclear. Each one is understood as the dynamics of a field. The gravitational force is modeled as a continuous classical field. The other three are each modeled as discrete quantum fields, and exhibit a measurable unit or elementary particle.Gravitation and electromagnetism act over a potentially infinite distance across the universe. They mediate macroscopic phenomena every day. The other two fields act over minuscule, subatomic distances. The strong nuclear interaction is responsible for the binding of atomic nuclei. The weak nuclear interaction also acts on the nucleus, mediating radioactive decay.Theoretical physicists working beyond the Standard Model seek to quantize the gravitational field toward predictions that particle physicists can experimentally confirm, thus yielding acceptance to a theory of quantum gravity (QG). (Phenomena suitable to model as a fifth force—perhaps an added gravitational effect—remain widely disputed). Other theorists seek to unite the electroweak and strong fields within a Grand Unified Theory (GUT). While all four fundamental interactions are widely thought to align at an extremely minuscule scale, particle accelerators cannot produce the massive energy levels required to experimentally probe at that Planck scale (which would experimentally confirm such theories). Yet some theories, such as the string theory, seek both QG and GUT within one framework, unifying all four fundamental interactions along with mass generation within a theory of everything (ToE).
