The Wikipedia article of the day for July 29, 2017 is Isidor Isaac Rabi.
Isidor Isaac Rabi (1898–1988) was an American physicist and Nobel laureate. Born on 29 July 1898 into a traditional Jewish family in what was then part of Austria-Hungary, Rabi came to the United States as a baby and was raised in New York's Lower East Side. In collaboration with Gregory Breit, he developed the Breit-Rabi equation, and predicted that the Stern–Gerlach experiment could be modified to confirm the properties of the atomic nucleus. During World War II he worked on radar at the MIT Radiation Laboratory, and on the Manhattan Project. He was awarded the Nobel Prize for Physics in 1944 for his discovery of nuclear magnetic resonance, used in spectroscopy and imaging. He was also one of the first scientists in the US to work on the cavity magnetron, a key component in microwave radar and microwave ovens. After the war, he served on the General Advisory Committee of the Atomic Energy Commission, and was its chairman from 1952 to 1956. He was Science Advisor to President Dwight D. Eisenhower, and was involved in the creation of the Brookhaven National Laboratory (1947) and CERN (1954).
