Science and the Unseen World by Sir Arthur Stanley Eddington... This book attempts to shed light on a world that lies beyond the world that physics can describe. Eddington starts from scientific premises, as usual, wondering whether the methods of science are capable of explaining that invisible world, or at least inaugurating a method capable of revealing the secrets of that unseen world, but he starts, as usual, from his physical knowledge, and tries, using it and his scientific method, to explore the depths of that hidden thing. Eddington, the famous astronomer, mathematician, and physicist, was the first to prove Einstein's general theory, the first to write about it in English. Einstein himself praised him when he said that what he wrote was the most accurate thing ever written about relativity in any language. He contributed to the development of non-Euclidean geometry, which helped greatly in providing a valid geometry for understanding the world in light of the theory of relativity itself. He did not stop there, but he had many of his own studies on the origin, development, movement, and structure of stars. He was also one of the first enthusiasts of quantum theory. Thus, we see in this book the approach of one of the smartest scientific minds of the twentieth century to the matter of that secret and his point of view regarding it, which is the vision that sails us between the shores of science, philosophy and religion and fills souls with inspiration.
