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
Unified Theory (band) to tour in support of their album. However, the tour was soon cancelled after Blind Melon parted ways with Warren. The band were to perform a number of shows with Thorn and Smith's former band mate Shinn, though a lack of preparation time resulted in the band cancelling the tour. Unified Theory released their second album "Cinematic" on iTunes in December 2006. The band did not reunite to perform any shows to promote the album. Unified Theory reunited for one show on August 4, 2010 at the King King in Hollywood. Chris Shinn's other band Everything is Energy opened the
