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) the character of the band members. Comparisons were also made between vocalist Chris Shinn and Shannon Hoon, due to their similar vocal styles and lyrical content, though Allmusic writer Greg Prato believes Shinn has "brought a more modern rock sound to the proceedings."

The lineup consisted of Chris Shinn (lead vocals, rhythm guitar), formerly of Celia Green, former Blind Melon members Christopher Thorn (lead guitar) and Brad Smith (bass) as well as Dave Krusen (drums) formerly of Pearl
