Who is This Fermi and Why Does He Ask Questions?. . . Fermi questions receive their name from Enrico Fermi (1901-1954). He was an Italian physicist known for his participation in the Los Alamos atomic bomb project (code named the “Manhattan Project”) during World War II. Fermi is best known for his contributions to nuclear physics and the development of quantum theory. In addition to his contribution to theory, he is also noted as an experimentalist..
