About this book

Atoms, electricity and energy develop as connected lines of inquiry in Isaac Asimov's account of nuclear science. This first volume begins with John Dalton's attempts to compare the weights of atoms, using the proportions of hydrogen and oxygen in water. Later measurements refine those early figures, while Michael Faraday's work raises the possibility that electricity also comes in small units. The explanations introduce scientific terms through particular experiments and numerical examples.

The discussion of isotopes shows why atoms of the same element can have different masses. Lead and neon provide examples, and the description of Thomson's apparatus explains how curved paths revealed two kinds of neon atoms. Readers interested in the foundations of atomic physics can follow how measurements prompted new ideas about matter. The book's historical approach makes changing models and experimental evidence the thread of its explanation.
