Understanding Nuclear Energy and Its History

The video explores the history and development of nuclear energy, starting with early skepticism from scientists like Robert Millikan and Rutherford. It discusses Becquerel's accidental discovery of radioactivity and Einstein's E=mc², which inspired science fiction writers. The challenges of nuclear reactions are highlighted, particularly the difficulty of altering atomic nuclei. The discovery of the neutron by Leo Szilard revolutionized nuclear physics, enabling controlled nuclear chain reactions and the development of atomic bombs. The video concludes with an Audible sponsorship and audiobook recommendations.
