"The Spark of Physics and Mathematics: "A Centennial Story of Relativity" focuses on the century-old history since Einstein completed the research results of general relativity in 1915. It tells the process of Einstein and his collaborators creating the general theory of relativity, reviews the origin of the big bang theory, and introduces general relativity, astronomy, quantum mechanics, quantum gravity, and information. The relationship between basic issues in physics such as breath theory and condensed matter physics and black holes is described, and it describes the principles and methods of directly measuring gravitational waves by combining numerical relativity and gravitational wave detection instruments... By reviewing the arduous process of predecessors in developing scientific theories, the book inspires people to explore the unknown, advocate science, and pursue the truth.
