Ravi Vakil, described in the San Francisco Chronicle as a legend in the world of math competitions has finally released his long-awaited second edition of A Mathematical Mosaic: Patterns & Problem Solving. Regarded by many as a seminal book in the field of mathematics competitions, the first edition of A Mathematical Mosaic has received wide acclaim from mathematics teachers, professors and the mathematics community at large. In the pages of this book, Ravi shares what mathematics is really about: beauty, elegance, and the discovery of deep and interconnected patterns. These patterns of nature are often best understood through puzzles and problems, both easy and hard. He also profiles eleven other Olympiad winners including Noam Elkies, the youngest professor to receive tenure at Harvard. This book is a must for teachers seeking to challenge their best students, and for students preparing for mathematics competitions. - from Amzon
