In physics, a unified field theory (UFT), occasionally referred to as a uniform field theory, is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a single field.
There is no accepted unified field theory, and thus it remains an open line of research. The term was coined by Einstein, who attempted to unify the general theory of relativity with electromagnetism. The " theory of everything" and Grand Unified Theory are closely related to unified field theory, but differ by not requiring the basis of nature to be fields, and often by attempting to explain physical constants of nature.
This article describes unified field theory as it is currently understood in connection with quantum theory. Earlier attempts based on classical physics are described in the article on classical unified field theories.
There may be no a priori reason why the correct description of nature has to be a unified field theory. However, this goal has led to a great deal of progress in modern theoretical physics and continues to motivate research.
Usage examples of "unified field theory".
It was his notion that once we tied Planck's constant to the speed of light, we would not only have the practical effect of miniaturizing and deminiaturizing in an essentially energy-free manner, but that we would have the theoretical effect of being able to work out the connection between quantum theory and relativity and finally have a good unified field theory.
Einstein said that the reason he could spend the last quarter-century of his life in a search (unsuccessful) for a unified field theory was that he could afford to.
A flavour of the material is given by these monograph titles: ``The Unique Brain Development of the Chrysto-peds of Srom Norba X', `Fire Worship and Sacrifice on Srom Sodrat IF, `The History of the Intergalactic Scientific Institute', and `The Application of Unified Field Theory and the Mechanics of the Stardrive to Space Travel'.
It takes little imagination to picture him pondering unified field theory in the Institute's quiet, lonely, almost ascetic surroundings.
The triangular Unified Field Theory diagram he had drawn for Yagharek was at the top of the papers that covered it.
Antonescu's unified field theory settled that in pre-Federation times.
Einstein spent half his life searching for that single set--for a Unified Field Theory--and failed.
My work has always been involved with the theory of particle movement, sub-atomic particles that is, and their relation to the unified field theory&hellip.
