... (b) The net electric field points in the –x direction, or 180 counterclockwise from the +x axis. 14. For it to be possible for the net field to vanish at some x > 0, the two individual fields (caused by q1 and q2) must point in opposite directions for x > 0. Given their locations in the figure, we ...

... • The algorithm can be looked upon as evolution of the quantum state from jsi to jt i, governed by a Hamiltonian containing two terms, jt iht j and jsihsj. The former represents a potential energy attracting the state toward jt i, and the latter represents a kinetic energy diffusing the state throug ...

... Newton’s first law of motion, supports the Abraham momentum [2,4]. The recoil of an absorbing or radiating atom in a medium [5,6] and the phenomenon of diffraction [7], however, argue with equal weight for the Minkowski momentum. Application of the Lorentz force law to the problem confirms the valid ...

Renormalization
In quantum field theory, the statistical mechanics of fields, and the theory of self-similar geometric structures, renormalization is any of a collection of techniques used to treat infinities arising in calculated quantities.Renormalization specifies relationships between parameters in the theory when the parameters describing large distance scales differ from the parameters describing small distances. Physically, the pileup of contributions from an infinity of scales involved in a problem may then result in infinities. When describing space and time as a continuum, certain statistical and quantum mechanical constructions are ill defined. To define them, this continuum limit, the removal of the ""construction scaffolding"" of lattices at various scales, has to be taken carefully, as detailed below.Renormalization was first developed in quantum electrodynamics (QED) to make sense of infinite integrals in perturbation theory. Initially viewed as a suspect provisional procedure even by some of its originators, renormalization eventually was embraced as an important and self-consistent actual mechanism of scale physics in several fields of physics and mathematics. Today, the point of view has shifted: on the basis of the breakthrough renormalization group insights of Kenneth Wilson, the focus is on variation of physical quantities across contiguous scales, while distant scales are related to each other through ""effective"" descriptions. All scales are linked in a broadly systematic way, and the actual physics pertinent to each is extracted with the suitable specific computational techniques appropriate for each.
