Nuclear fission

principle · 1938 · Electric age

A uranium nucleus splits, releasing energy and neutrons (Hahn, Meitner).

Principles and materials it uses

E = mc² — uses. The energy is the mass defect.
Neutron — uses. Fission by neutrons.

Where it is used

Chain reaction — is used in. Fission neutrons cause new fissions.
Small modular reactor — is used in. Nuclear fission provides the heat.

History: what it evolved from and what it influenced

Radioactivity — evolved from. Studying radioactive decay led to the discovery of fission.
