l. F.W. Aston, “The Mass-Spectra of Chemical Elements,” Philosophical Magazine and Journal of Science, 39, 611-625 (1920). In the course of a systematic program to measure the masses of atoms, Aston found that four hydrogen nuclei (protons) are heavier than a helium nucleus (an alpha particle) and two positive electrons [see Eq. (1)]. This fundamental discovery is the experimental basis of our understanding of how stars like the sun shine. The original paper is rarely cited, perhaps because the text is mainly devoted to a description of Aston’s new apparatus and to a discussion of the many different masses that he measured. The hydrogen-helium mass difference is only briefly discussed.

The author tells an exciting story with historical accuracy.

21. H.N. Russell, “On the Sources of Stellar Energy,” Pub. Ast. Soc. Pacific, August (1919). If you like to read mystery stories and to figure out “Who did it” from limited clues, then you will love this paper. A year before Aston’s measurements of the mass of hydrogen and of helium and two decades before Bethe’s calculations of nuclear fusion rates, Russell used well-known observations of stars and simple physical reasoning to infer that the rate of the “unknown process” that supplies stellar energy must increase rapidly with increasing stellar temperature. Incredibly, he also correctly deduced that this dependence of energy production on temperature would lead to stars being stable over very long periods of time. These insights are presented in the text of a closely-reasoned lecture that contains no equations.
