Richard Phillips Feynman (/fanmn/; May 11, 1918 February 15, 1988) was an American theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all time.

The Cold War saw periods of both heightened tension and relative calm. International crises arose, such as the Berlin Blockade (19481949), the Korean War (19501953), the Berlin Crisis of 1961, the Vietnam War (19591975), the Cuban Missile Crisis (1962), the Soviet war in Afghanistan (19791989) and NATO exercises in November 1983. There were also periods of reduced tension as both sides sought detente. Direct military attacks on adversaries were deterred by the potential for mutual assured destruction using deliverable nuclear weapons. In the Cold War era, the Generation of Love and the rise of computers changed society in very different, complex ways, including higher social and local mobility.
Through what time period did the Berlin Blockade last?
A: 19481949

In 1941, the General Anaya borough was merged to the Central Department, which was then renamed "Mexico City" (thus reviving the name, but not the autonomous municipality). From 1941 to 1970, the Federal District comprised twelve delegaciones and Mexico City. In 1970 Mexico City was split into four different delegaciones: Cuauhtemoc, Miguel Hidalgo, Venustiano Carranza and Benito Juarez, increasing the number of delegaciones to sixteen. Since then, in a de facto manner, the whole Federal District, whose delegaciones had by then almost formed a single urban area, began to be considered a synonym of Mexico City.
Which boroughs was the Mexico City borough split into?
A: Cuauhtemoc, Miguel Hidalgo, Venustiano Carranza and Benito Juarez
