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 Launch Vehicle Lift Launch Vehicle(HLV-Variant):- A potential heavy-lift variant (HLV) of the unified launcher capable of placing up to 10 ton class of spacecrafts into Geosynchronous Transfer Orbit would include: Unified Launch Vehicle The Unified Launch Vehicle (ULV) is a development project by the Indian Space Research Organisation (ISRO) whose core objective is to design a modular architecture that could eventually replace the PSLV, GSLV Mk I/II and LVM3 with a single family of launchers. The design may include a heavy-lift variant dubbed HLV, as well as super heavy-lift variant called SHLV with a cluster stage of five SCE-200 engines each replacing
