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 Command of the area east of the canal (Egypt) Unified Command of the area east of the canal (Egypt) The Unified command of the area east of the canal is an Egyptian military formation. It groups the Second Field Army and the Third Field Army. A presidential Decree from Abdel Fattah al-Sisi appointed the command's first commander, Lieutenant General Osama Askar. The command was created to combat terrorism in the Sinai, and the unity of command and coordination between the second and third armies. President Abdel Fattah el-Sisi chaired a meeting of the Supreme Council of the Armed Forces in January 2015, during which he issued two declarations. The
