The Soma cube is one of the most famous mechanical puzzles in the world. The main challenge is to build a cube or other structures from all seven pieces. The puzzles in this collection use the pieces as building blocks only, and showcase many versatile challenges, from all types of recreational mathematics fields. For example, you will find symmetry puzzles, cover-up puzzles and even fraction puzzles. The chapters are divided according to the number of pieces used; from single-piece puzzles to puzzles requiring a complete set. From the moment we changed the rules, we felt that the sky is the limit! There is something magical and enchanting in those seven pieces that enabled us to find many puzzles and challenges! Most of the puzzles demonstrated are new and original. Some are based on classic puzzles, as well as more modern ones, modified and presented by using the set of Soma pieces. This is a unique collection of puzzles - all you need is a set of the Soma cube. The puzzles range from easy to difficult and they appeal to a wide audience - all within the reach of the general public. It presents many geometrical and mathematical principals, and makes them easier to understand. However, no special knowledge in mathematics or geometry is required.

Sidney Coleman was a physicist's physicist. He is largely unknown outside of the theoretical physics community, and known only by reputation to the younger generation. He was an unusually effective teacher, famed for his wit, his insight and his encyclopedic knowledge of the field to which he made many important contributions. There are many first-rate quantum field theory books (the ancient Bjorken and Drell, the more modern Itzykson and Zuber, the now-standard Peskin and Schroder, and the recent Zee), but the immediacy of Prof. Coleman's approach and his ability to present an argument simply without sacrificing rigor makes his book easy to read and ideal for the student. Part of the motivation in producing this book is to pass on the work of this outstanding physicist to later generations, a record of his teaching that he was too busy to leave himself.
