Leonard Susskind, a famous American physicist and one of the creators of string theory, once proposed a revolutionary concept for understanding the Universe and man's place in it. With his research, Susskind inspired a galaxy of modern physicists who believed that this theory could unambiguously predict the properties of our Universe. Now, in his first book for a wide range of readers, Susskind clarifies and rethinks his views, arguing that this idea is by no means universal and will have to give way to the much broader concept of a gigantic “cosmic landscape.” Research at the beginning of the 21st century allowed science to rise to a new level in understanding the world, says Susskind. And this fascinating book, which takes the reader to the front lines of battles in modern physics, is a clear confirmation of this.
