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 settlement planning and Planning - 2032, on 18 & 19 April 2012. The seminar has strongly recommended that the development of rural and urban settlements in India should not be planned separately. The fundamental objective for a unified settlement plan includes: The strategies for achieving the objectives include: Unified settlement planning Unified settlement planning (USP) is the component of regional planning where a unified approach is applied for a region's overall development. The USP approach is most often associated with urban planning practices in India. Regions use their land in for various purposes, including agriculture, manufacturing, and public administration.
