Our lives have benefited immensely from the scientific evolution over the years. This book provides an overview of the lives of three great scientists, Newton, Faraday and Einstein, who made the most significant contributions to physics. Newton and Faraday laid the foundation of Newtonian mechanics and electro-magnetic theory, respectively, that constituted the two greatest contributions to classical physics. Newton elucidated the motion of celestial bodies with the three laws of motion, while Faraday researched electro-magnetic phenomena and discovered electro-magnetic induction, magneto-optical effect, etc. Furthermore, Einstein contributed to the foundation of quantum mechanics and relativity theory which comprise the two greatest theories in modern physics. By elucidating photoelectric effect, Einstein proved the correctness of the concept of quantum proposed by Planck which resulted in quantum mechanics being considered as an epoch-making mechanics following Newtonian mechanics. Einstein renovated the concept of time-space and derived the Lorentz transformation supporting relativity principle. This book will take the readers on a journey to understand the progress from classical physics to modern physics.
