Frederick Reines

Frederick Reines ();〔 (March 16, 1918 – August 26, 1998) was an American physicist. He was awarded the 1995 Nobel Prize in Physics for his co-detection of the neutrino with Clyde Cowan in the neutrino experiment. He may be the only scientist in history "so intimately associated with the discovery of an elementary particle and the subsequent thorough investigation of its fundamental properties".
A graduate of the Stevens Institute of Technology and New York University, Reines joined the Manhattan Project's Los Alamos Laboratory in 1944, working in the Theoretical Division in Richard Feynman's group. He became a group leader there in 1946. He participated in a number of nuclear tests, culminating in his becoming the director of the Operation Greenhouse test series in the Pacific in 1951.
In the early 1950s, working in Hanford and Savannah River Sites, Reines and Cowan developed the equipment and procedures with which they first detected the supposedly undetectable neutrinos in June 1956. Reines dedicated the major part of his career to the study of the neutrino's properties and interactions, which work would influence study of the neutrino for many researchers to come. This included the detection of neutrinos created in the atmosphere by cosmic rays, and the 1987 detection of neutrinos emitted from Supernova SN1987A, which inaugurated the field of neutrino astronomy.
== Early life ==
Frederick Reines was born in Paterson, New Jersey, one of four children of Gussie (Cohen) and Israel Reines. His parents were Jewish emigrants from the same town in Russia, but only met in New York City, where they were later married. He had an older sister, Paula, who became a doctor, and two older brothers, David and William, who became lawyers. He said that his "early education was strongly influenced" by his studious siblings. He was the great-nephew of the Rabbi Yitzchak Yaacov Reines, the founder of Mizrachi, a religious Zionist movement.
The family moved to Hillburn, New York, where his father ran the general store, and he spent much of his childhood. He was an Eagle Scout. Looking back, Reines said: "My early childhood memories center around this typical American country store and life in a small American town, including Independence Day July celebrations marked by fireworks and patriotic music played from a pavilion bandstand."〔(【引用サイトリンク】publisher=Nobel Foundation )
Reines sang in a chorus, and as a soloist. For a time he considered the possibility of a singing career, and was instructed by a vocal coach from the Metropolitan Opera who provided lessons for free because the family did not have the money for them.〔 The family later moved to North Bergen, New Jersey, residing on Kennedy Boulevard and 57th Street. Because North Bergen did not have a high school, he attended Union Hill High School in Union Hill, New Jersey,〔〔 from which he graduated in 1935.〔
From an early age, Reines exhibited an interest in science, and liked creating and building things. He later recalled that:
The first stirrings of interest in science that I remember occurred during a moment of boredom at religious school, when, looking out of the window at twilight through a hand curled to simulate a telescope, I noticed something peculiar about the light; it was the phenomenon of diffraction. That began for me a fascination with light.〔

Ironically, Reines excelled in literary and history courses, but received average or low marks in science and math in his freshman year of high school, though he improved in those areas by his junior and senior years through the encouragement of a teacher who gave him a key to the school laboratory. This cultivated a love of science by his senior year. In response to a question seniors were asked about what they wanted to do for a yearbook quote, he responded: "To be a physicist extraordinaire."〔
Reines was accepted into the Massachusetts Institute of Technology, but chose instead to attend Stevens Institute of Technology in Hoboken, New Jersey, where he earned his Bachelor of Science (B.S.) degree in mechanical engineering in 1939, and his Master of Science (M.S.) degree in mathematical physics in 1941, writing a thesis on "A Critical Review of Optical Diffraction Theory".〔 He married Sylvia Samuels on August 30, 1940.〔 They had two children, Robert and Alisa.〔 He then entered New York University, where he earned his Doctor of Philosophy (Ph.D.) in 1944. He studied cosmic rays there under Serge A. Korff,〔 but wrote his thesis under the supervision of Richard D. Present〔 on "Nuclear fission and the liquid drop model of the nucleus".〔(【引用サイトリンク】publisher=New York University )〕 Publication of the thesis was delayed until after the end of World War II; it appeared in Physical Review in 1946.〔
