Frederick Reines’s zodiac sign is Aries. According to astrologers, the presence of Aries always marks the beginning of something energetic and turbulent. They are continuously looking for dynamic, speed and competition, always being the first in everything - from work to social gatherings. Thanks to its ruling planet Mars and the fact it belongs to the element of Fire (just like Leo and Sagittarius), Aries is one of the most active zodiac signs. It is in their nature to take action, sometimes before they think about it well.
Frederick Reines was born in the Year of the Horse. Those born under the Chinese Zodiac sign of the Horse love to roam free. They’re energetic, self-reliant, money-wise, and they enjoy traveling, love and intimacy. They’re great at seducing, sharp-witted, impatient and sometimes seen as a drifter. Compatible with Dog or Tiger.
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.
The neutrino was a subatomic particle first proposed theoretically by Wolfgang Pauli on December 4, 1930, to explain undetected Energy that escaped during beta decay when neutron decayed into a proton and an electron so that the law of conservation of Energy was not violated. Enrico Fermi renamed it the neutrino, Italian for "little neutral one", and in 1934, proposed his theory of beta decay which explained that the electrons emitted from the nucleus were created by the decay of a neutron into a proton, an electron, and a neutrino:
The neutrino accounted for the missing Energy, but Fermi's theory described a particle with little mass and no electric charge that would be difficult to observe directly. In a 1934 paper, Rudolf Peierls and Hans Bethe calculated that neutrinos could easily pass through the Earth, and concluded "there is no practically possible way of observing the neutrino." In 1951, at the conclusion of the Greenhouse test series, Reines received permission from the head of T Division, J. Carson Mark, for a leave in residence to study fundamental physics. Reines and his colleague Clyde Cowan decided to see if they could detect neutrinos. "So why did we want to detect the free neutrino?" he later explained, "Because everybody said, you couldn’t do it."
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.
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". Publication of the thesis was delayed until after the end of World War II; it appeared in Physical Review in 1946.
In 1944 Richard Feynman recruited Reines to work in the Theoretical Division at the Manhattan Project's Los Alamos Laboratory, where he would remain for the next fifteen years. He joined Feynman's T-4 (Diffusion Problems) Group, which was part of Hans Bethe's T (Theoretical) Division. Diffusion was an important aspect of critical mass calculations. In June 1946, he became a group leader, heading the T-1 (Theory of Dragon) Group. An outgrowth of the "tickling the Dragon's tail" experiment, the Dragon was a machine that could attain a critical state for short bursts of time, which could be used as a research tool or power source.
Reines participated in a number of nuclear tests, and writing reports on their results. These included Operation Crossroads at Bikini Atoll in 1946, Operation Sandstone at Eniwetok Atoll in 1948, and Operation Ranger and Operation Buster–Jangle at the Nevada Test Site. In 1951 he was the Director of Operation Greenhouse series of nuclear tests in the Pacific. This saw the first American tests of boosted fission weapons, an important step towards thermonuclear weapons. He studied the effects of nuclear blasts, and co-authored a paper with John von Neumann on Mach stem formation, an important aspect of an air blast wave.
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.
In 1953, they made their first attempts using one of the large reactors at the Hanford nuclear site in what is now known as the Cowan–Reines neutrino experiment. Their detector now included 300 litres (66 imp gal; 79 US gal) of scintillating fluid and 90 photomultiplier tubes, but the effort was frustrated by background noise from cosmic rays. With encouragement from John A. Wheeler, they tried again in 1955, this time using one of the newer, larger 700 MW reactors at the Savannah River Site that emitted a high neutrino flux of 1.2 x 10 / cm sec. They also had a convenient, well-shielded location 11 metres (36 ft) from the reactor and 12 metres (39 ft) underground. On June 14, 1956, they were able to send Pauli a telegram announcing that the neutrino had been found. When Bethe was informed that he had been proven wrong, he said, "Well, you shouldn’t believe everything you read in the papers."
In spite or perhaps because of his role in these nuclear tests, Reines was concerned about the dangers of radioactive pollution from atmospheric nuclear tests, and became an advocate of underground nuclear testing. In the wake of the Sputnik crisis, he participated in John Archibald Wheeler's Project 137, which evolved into JASON. He was also a delegate at the Atoms for Peace Conference in Geneva in 1958.
In 1966, Reines took most of his neutrino research team with him when he left for the new University of California, Irvine (UCI), becoming its first dean of physical sciences. At UCI, Reines extended the research interests of some of his graduate students into the development of medical radiation detectors, such as for measuring total radiation delivered to the whole human body in radiation therapy.
Reines had prepared for the possibility of measuring the distant events of a supernova explosion. Supernova explosions are rare, but Reines thought he might be lucky enough to see one in his lifetime, and be able to catch the neutrinos streaming from it in his specially-designed detectors. During his wait for a supernova to explode, he put signs on some of his large neutrino detectors, calling them "Supernova Early Warning Systems". In 1987, neutrinos emitted from Supernova SN1987A were detected by the Irvine–Michigan–Brookhaven (IMB) Collaboration, which used an 8,000 ton Cherenkov detector located in a salt mine near Cleveland. Normally, the detectors recorded only a few background events each day. The supernova registered 19 events in just ten seconds. This discovery is regarded as inaugurating the field of neutrino astronomy.
In 1995, Reines was honored, along with Martin L. Perl with the Nobel Prize in Physics for his work with Cowan in first detecting the neutrino. Unfortunately, Cowan had died in 1974, and the Nobel Prize is not awarded posthumously. Reines also received many other awards, including the J. Robert Oppenheimer Memorial Prize in 1981, the National Medal of Science in 1985, the Bruno Rossi Prize in 1989, the Michelson–Morley Award in 1990, the Panofsky Prize in 1992, and the Franklin Medal in 1992. He was elected a member of the National Academy of Sciences in 1980 and a foreign member of the Russian Academy of Sciences in 1994. He remained dean of physical sciences at UCI until 1974, and became a professor emeritus in 1988, but he continued teaching until 1991, and remained on UCI's faculty until his death.
Reines died after a long illness at the University of California, Irvine Medical Center in Orange, California, on August 26, 1998. He was survived by his wife and children. His papers are in the UCI Libraries. Reines Hall at UCI was named in his honor.
From then on 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 Future researchers to come. Cowan left Los Alamos in 1957 to teach at George Washington University, ending their collaboration. On the basis of his work in first detecting the neutrino, Reines became the head of the physics department of Case Western Reserve University from 1959 to 1966. At Case, he led a group that was the first to detect neutrinos created in the atmosphere by cosmic rays. Reines had a booming voice, and had been a singer since childhood. During this time, besides performing his duties as a research supervisor and chairman of the physics department, Reines sang in the Cleveland Orchestra Chorus under the direction of Robert Shaw in performances with George Szell and the Cleveland Orchestra.
