Classical unified field theories to isospin rather than electromagnetism; this is related to a discrete (or ""internal"") symmetry known to Einstein as "displacement field duality". Einstein became increasingly isolated in his research on a generalized theory of gravitation, and most physicists consider his attempts ultimately unsuccessful. In particular, his pursuit of a unification of the fundamental forces ignored developments in quantum physics (and vice versa), most notably the discovery of the strong nuclear force and weak nuclear force. Inspired by Einstein's approach to a unified field theory and Eddington's idea of the affine connection as the sole basis for differential geometric structure for space-time,
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. For society to
