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
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
