RADIOACTIVITY

Maxwell''s equations of the electromagnetic field contributed to the development of research on radioactivity where light is considered as a quantum of energy with the property of a wave - corpuscle. And using the laws of special relativity theory the research developed to the discovery of new particles which led to the emergence of quantum field theory which played a key role in the development of particle physics and the discovery of new forces in addition to gravity and electromagnetism. In this book a brief history of radioactivity the elementary particles discovered and the contributions of relativistic quantum mechanics are presented.
