With the discovery, between 1845 and 1847, of the principle of conservation of energy, the importance of energy for human life and progress was recognized, and scientists gave energy the romantic name of `The Queen of the Worldâ. Some twenty years later scientists discovered entropy, a measure of the dissipation of energy. This book outlines the history of the formulation of these two notions. Ideas and concepts that were crystallizing in the human mind for thousands of years as the result of observation, practical experience, and developments in technology are described, together with philosophers, scientists, engineers, and inventors who contributed to their formulation.
