Unified field theory 1820 Hans Christian Ørsted discovered that electric currents exerted forces on magnets, while in 1831, Michael Faraday made the observation that time-varying magnetic fields could induce electric currents. Until then, electricity and magnetism had been thought of as unrelated phenomena. In 1864, Maxwell published his famous paper on a dynamical theory of the electromagnetic field. This was the first example of a theory that was able to encompass previously separate field theories (namely electricity and magnetism) to provide a unifying theory of electromagnetism. By 1905, Albert Einstein had used the constancy of the speed of light in Maxwell's theory to
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
