Nuclear Energy Explained: How does it work? 1/3
Kurzgesagt – In a Nutshell · 2015
Lays out, in plain terms, how splitting a uranium nucleus releases energy and how a reactor controls the chain reaction to turn that into electricity.
Assumes you know the vocabulary.
Nobel Lecture: The Chemical Nature of the Alpha Particles from Radioactive Substances
Ernest Rutherford · 1908
Establishes that the alpha particles thrown off by radioactive elements are helium nuclei, tying radioactive decay directly to the transmutation of…

Establishes that the alpha particles thrown off by radioactive elements are helium nuclei, tying radioactive decay directly to the transmutation of one element into another.

Recounts the chemical evidence that bombarding uranium with neutrons splits the nucleus into much lighter elements, releasing far more energy than any known chemical reaction.

Covers nuclear reactions through the compound-nucleus picture Bohr introduced in 1936 — a reaction as formation of a short-lived intermediate state sharing its energy among all nucleons, then decaying independently of how it formed.

Describes the first electrical counter for individual alpha particles, replacing counting scintillation flashes by eye and founding quantitative radiation detection.

Reports the experiments identifying a neutral particle of roughly proton mass ejected from beryllium under alpha bombardment, establishing the neutron as a fundamental nuclear constituent.

Proposes that a neutron striking a nucleus first forms a short-lived compound nucleus sharing its energy among all nucleons before decaying, explaining the resonance peaks in reaction cross sections.
Maria Goeppert Mayer
Explains why nuclei with certain 'magic numbers' of protons or neutrons are unusually stable, by treating nucleons as independent particles filling shells much as electrons fill shells in atoms.

Works out the chain of nuclear fusion reactions that fuses hydrogen into helium and keeps the sun and other stars burning for billions of years.
