About the Authors
  • The distinguished mathematician John Conway presents quadratic forms in a pictorial way that enables the reader to understand them mathematically without proving theorems in the traditional fashion. One learns to sense their properties. In his customary enthusiastic style, Conway uses his theme to cast light on all manner of mathematical topics from algebra, number theory and geometry, including many new ideas and features.

    • Conway is a very distinguished mathematician and well-known author
    • Contains many original insights into the subject
    • Can be appreciated without formal mathematical training
