Unified field theory classical field theory and, two years later, that of Theodor Kaluza, who extended General Relativity to five dimensions. Continuing in this latter direction, Oscar Klein proposed in 1926 that the fourth spatial dimension be curled up into a small, unobserved circle. In Kaluza–Klein theory, the gravitational curvature of the extra spatial direction behaves as an additional force similar to electromagnetism. These and other models of electromagnetism and gravity were pursued by Albert Einstein in his attempts at a classical unified field theory. By 1930 Einstein had already considered the Einstein–Maxwell–Dirac System [Dongen]. This system is (heuristically) the super-classical [Varadarajan] limit
Unified Theory (band) "a little too much like its members' former projects." However, "there are a couple of unique gems in the derivative dust." "The Stranger" stated that the album "sounds like Jane's Addiction, but not as hard." "Classic Rock" stated that the band's "self-titled debut has to be one of the most exciting, spiritual albums of recent times" and that "their sound combines flashes of the off-the-wall genius that was Blind Melon's calling card, the odd reminder of the 90s Seattle scene and a whole host of fascinating influences." In support of the album, Unified Theory performed a number of dates in
