Worlds Within Worlds: The Story of Nuclear Energy, Volume 2 (of 3): Mass and Energy; The Neutron; The Structure of the Nucleus

"Worlds Within Worlds: The Story of Nuclear Energy, Volume 2 (of 3)" by Isaac Asimov is a scientific publication written during the early 1970s. This book, part of a three-volume series, explores the foundations and implications of nuclear energy, including concepts such as mass and energy, the neutron, and the structure of the atomic nucleus. Asimov aims to elucidate the complex science behind nuclear energy for the general public, reflecting on its transformative impact on society. In this volume, Asimov delves into the intricate relationship between mass and energy, presenting the groundbreaking theory of mass-energy equivalence articulated by Einstein, encapsulated in the famous equation E=mc². He further explains the structure of atomic nuclei, introducing essential concepts such as protons and neutrons, and provides insights into the development of nuclear physics, including nuclear bombardment and the discovery of neutrons. Through engaging explanations and historical context, Asimov illustrates how these scientific advancements pave the way for understanding nuclear reactions and their potential for immense energy generation, while also highlighting the challenges and consequences of harnessing such power.
