The Little Book of String Theory covers vast territory, from the first superstring revolution, when physicists proposed that strings might account for all particles and forces of nature, to the second revolution, when they realised that string theory is barely about strings. He describes possible experimental tests of the theory and the many theoretical challenges that lie ahead, all in an engaging,…
