Summary
Updated 2026-06-21

He built the first nuclear reactor in a squash court beneath the University of Chicago and stood in the New Mexico desert calculating the yield of the Trinity blast by dropping scraps of paper. Fermi worked both sides of physics — the equations and the hardware — and did both at the highest level.

Biography

About

Enrico Fermi made his name in statistical mechanics in the 1920s, applying Pauli's exclusion principle to ideal gases in what became Fermi–Dirac statistics; particles obeying that principle are now called fermions. He developed a theory of beta decay incorporating a particle he named the neutrino, describing what's now known as weak interaction, one of the four fundamental forces. His neutron experiments led him to discover that slow neutrons were more easily captured by nuclei, work for which he won the 1938 Nobel Prize — though what he thought were new elements turned out to be fission produ…

There are two possible outcomes: if the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery.
