Classical unified field theories since antisymmetry seemed essential for electromagnetism, the symmetry requirement was relaxed for one or both fields. Einstein's proposed unified-field equations (fundamental laws of physics) were generally derived from a variational principle expressed in terms of the Riemann curvature tensor for the presumed space-time manifold. In field theories of this kind, particles appear as limited regions in space-time in which the field strength or the energy density are particularly high. Einstein and coworker Leopold Infeld managed to demonstrate that, in Einstein's final theory of the unified field, true singularities of the field did have trajectories resembling point particles. However, singularities are
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
