Nuclear fission is the physical process in which the nucleus of an atom splits apart, releasing energy that has shaped science, industry, and global politics for nearly a century.Nuclear fission is the physical process in which the nucleus of an atom splits apart, releasing energy that has shaped science, industry, and global politics for nearly a century. This book traces that process from its discovery in the late 1930s through its development into both weapons and power generation. You will learn how fission works at the atomic level, how scientists first identified and explained it, and how nations applied this knowledge during and after the Second World War. The book also examines how nuclear power plants operate, the debates surrounding their safety and waste management, and the ongoing role of fission in energy policy today. Written to inform rather than persuade, it offers a clear, factual introduction to a subject that continues to influence technology and public debate. This book was generated by an artificial intelligence and reviewed for accuracy and clarity.Nuclear fission is the physical process in which the nucleus of an atom splits apart, releasing energy that has shaped science, industry, and global politics for nearly a century.
