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 The Unified Field / Quiet the Mind "The Unified Field" / "Quiet the Mind" is the first release, a double A-side, by IAMX and is taken from the fifth studio album "The Unified Field". On 19 October the name of the release was confirmed on IAMX's PledgeMusic page. The Unified Field The music video, which was filmed in Sydney, Australia, shows a homeless man on a street moving his hands as if playing a piano. He observes a tattooed man washing a car window and then leaving the window wiper down on a bench. The homeless man picks it up
