Ephraim Fischbach (born 1942) is an American physicist and a professor at Purdue University. He is best known for his attempts to find a fifth force of nature [1] and his research relating to the detection of neutrinos. [2] He has also done work relating to the prediction of solar flares [3] and the detection of radiation by cell phones. [4]

Fischbach studies variation in radioactive decay rates, suggesting that neutrino emission from the Sun reduces the rate of nuclear decay. [5] He reanalysed the Eötvös experiment, which he saw as evidence for a fifth physical force. [6] However, in 1992, he and Carrick Talmadge conducted an experiment which found no compelling evidence for a fifth force. [7]

Fischbach has been a fellow of the American Physical Society since 2001, and a professor at Purdue since 1979. He also was an associate professor at the Institute for Theoretical Physics in Stony Brook, New York from 1978 to 1979. He received a B.A. in physics in 1963 from Columbia University and a Ph.D. in 1967 from the University of Pennsylvania.
