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
Operation Unified Resolve Peshawar. Anti-coalition forces, led by former Afghan prime minister Gulbuddin Hekmatyar, have attacked coalition forces with their usual retinue of rockets, mines, and bobby traps. Hekmatyar has been organizing alliances between the remaining anti-coalition forces in the area and increasing their coordination. In addition to hunting the Taliban and al-Qaeda fighters, Operation Unified Resolve also distributes humanitarian assistance to the Afghan people in the nearby valleys. Operation Unified Resolve Operation Unified Resolve is an air and ground operation to flush out and trap al-Qaeda fighters hiding in the eastern Afghanistan provinces.
