Science is not born ready and perfect, a beautiful thing that rose from the foam of the ocean, but is the product of human beings who made mistakes, sweated, lied, stole the ideas of others, but sometimes received divine inspiration and discovered wonderful treasures. Felix Dotan describes the development of modern science and its principles in clear and fluent language, emphasizing the human aspect and accompanied by many stories and illustrations. In doing so, he presents the reader with a friendly science book that is accessible to all. The book begins with the dawn of chemistry and the nature of energy. From here, it moves on to deal extensively with the development of the theory of electricity and the great inventions that accompanied it. It then discusses the phenomena involved in the conduction of electricity in gases, X-rays, radioactivity, and the discoveries of elementary particles. The subsequent chapters deal with the structure of the atom and the nucleus, nuclear energy for the purposes of war and peace, and the future energy of thermonuclear fusion. The final chapter summarizes the fascinating discoveries of recent decades: neutron stars, exploding stars that radiate more energy in one second than the sun radiates in a million years, and black holes, mysterious structures whose existence has only been proven in recent years.
