Classical unified field theories a survey of classical relativistic field theories of gravitation that have been motivated by theoretical concerns other than unification, see Classical theories of gravitation. For a survey of current work toward creating a quantum theory of gravitation, see quantum gravity. The early attempts at creating a unified field theory began with the Riemannian geometry of general relativity, and attempted to incorporate electromagnetic fields into a more general geometry, since ordinary Riemannian geometry seemed incapable of expressing the properties of the electromagnetic field. Einstein was not alone in his attempts to unify electromagnetism and gravity; a large number of mathematicians and
The Unified Field / Quiet the Mind a carnival. Towards the end of the video, a man takes the window wiper away from the homeless man and the latter walks away until he reaches a cliffside. Again, he waves his hands like a conductor making the waves move in time until the song ends. He smiles. The concept of the video is based on the unified field theory. Quiet the Mind The music video, the fourth to be directed and edited by Chris in collaboration with Danny Drysdale, includes scenes of him playing the guitar and submerged up to his waist in a puddle of water wearing
