"In this slender volume, about a dozen experts reflect succinctly on a variety of currently interesting topics, from black hole entropy in string theory to the challenge of dark energy. The book should interest primarily graduate students in physics and also some undergraduates ... is a fine reflection of the internationalism of modern science that stretches across nations and continents, race, and religion."Choice"It provides a broad, clear and precise overview of how his five famous papers sowed the seeds of revolution of 20th-century physics. For many, including the authors of this book, he was certainly a hero and a model ... I certainly enjoyed the elegant approach of explaining abstract concepts and their future implications through the words of some of the renowned experts in the field."CERN Courier
