Theory of everything differ both from gravity and from electromagnetism. A further hurdle was the acceptance that in a TOE, quantum mechanics had to be incorporated from the start, rather than emerging as a consequence of a deterministic unified theory, as Einstein had hoped. Gravity and electromagnetism could always peacefully coexist as entries in a list of classical forces, but for many years it seemed that gravity could not even be incorporated into the quantum framework, let alone unified with the other fundamental forces. For this reason, work on unification, for much of the twentieth century, focused on understanding the three "quantum" forces:
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
