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
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.
