Gravity as an Emergent Phenomenon
... Currently, there exist several potential solutions to reconcile gravity with quantum mechanics, or at least discover the fundamental nature of gravity. The first and most intuitive solution for physicists is to quantize gravity just like how the electromagnetic fields have been. If the other forces ...

The effects of the Aharonov-Bohm type as tests of the relativistic
... Moving charges are considered by relativity to form a current regardless of the fact that the forces on currents and their fields have been tested on moving charges or current elements forming closed currents only. Thus, it turns out that, theoretically, there is some arbitrariness in the expression ...

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.
