The Fermi–Pustyl'nikov model, named after Enrico Fermi and Lev Pustyl'nikov, is a model of the Fermi acceleration mechanism.
Enrico Fermi ( ; ] ; 29 September 1901 – 28 November 1954) was an Italian physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1.
 He has been called the "architect of the nuclear age" and the "architect of the atomic bomb".
 He was one of the very few physicists in history to excel both theoretically and experimentally.
 Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements.
 He made significant contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics.
The Enrico Fermi Award is an award honoring scientists of international stature for their lifetime achievement in the development, use, or production of energy.
 It is administered by the U.S. government's Department of Energy.
 The recipient receives $50,000, a certificate signed by the President and the Secretary of Energy, and a gold medal featuring the likeness of Enrico Fermi.
Enfield High School is a secondary school established in 1893 in Enfield, Connecticut.
 The Enfield High School campus is located in the Connecticut River Valley, on Enfield Street (U.S. Route 5) in Enfield's Historical District.
 The school has an enrollment of approximately 1400 students.
 The present facility was built in 1964 on Enfield Street.
 The facility underwent a $6.2 million renovation and library addition completed in 2005, and a $103 million "as-new" renovation and significant expansion completed in 2017.
 In May 2010, Enfield High School and Enrico Fermi High School underwent a consolidation process as part of the restructuring and improvement plan of Enfield Public Schools.
 Enfield High School operates as the town's sole high school, which houses both students from Enfield High School and the previous Enrico Fermi High School, which closed its doors in 2016.
In physics or engineering education, a Fermi problem, Fermi quiz, Fermi question, Fermi estimate, or order estimation is an estimation problem designed to teach dimensional analysis, approximation, and such a problem is usually a back-of-the-envelope calculation.
 The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data.
 Fermi problems typically involve making justified guesses about quantities and their variance or lower and upper bounds.
Herbert Lawrence Anderson (May 24, 1914 – July 16, 1988) was an American nuclear physicist who contributed to the Manhattan Project.
 He was also a member of the team which made the first demonstration of nuclear fission in the United States, in the basement of Pupin Hall at Columbia University.
 He participated in the first atomic bomb test, codenamed Trinity.
 After the close of World War II, he was a professor of physics at the University of Chicago until 1982.
 There, he helped Fermi establish the Enrico Fermi Institute and was its director from 1958 to 1962.
 The latter part of his career was as a senior fellow at Los Alamos National Laboratory.
 He was a recipient of the Enrico Fermi Award.
 Anderson's lineage to Rabbi Meir Katzenellenbogen, the Maharam of Padua, is detailed in "The Unbroken Chain".
A Fermi gas is a phase of matter which is an ensemble of a large number of fermions (named after Enrico Fermi).
 Fermions are particles that obey Fermi–Dirac statistics.
 These statistics determine the energy distribution of fermions in a Fermi gas in thermal equilibrium, and is characterized by their number density, temperature, and the set of available energy states.
The Fermi paradox or Fermi's paradox, named after physicist Enrico Fermi, is the apparent contradiction between the lack of evidence and high probability estimates, for the existence of extraterrestrial civilizations.
 The basic points of the argument, made by physicists Enrico Fermi (1901–1954) and Michael H. Hart (born 1932), are:
Oscar D'Agostino (29 August 1901 – 16 March 1975) was an Italian chemist and one of the so-called "Via Panisperna boys", the group of young scientists led by Enrico Fermi: all of them were physicists, except for D'Agostino, who was a chemist.
The Institute for Nuclear Studies was founded September 1945 as part of the University of Chicago with Samuel King Allison as director.
 On November 20, 1955 it was renamed The Enrico Fermi Institute for Nuclear Studies.
 The name was shortened to The Enrico Fermi Institute (EFI) in January 1968.
