The Sensual (Quadratic) Form

The distinguished mathematician John Conway presents quadratic forms in a pictorial way that enables the reader to understand them mathematically without traditional theorem-proving. In his customary enthusiastic style, Conway uses his theme to elucidate many mathematical topics from algebra, number theory and geometry, including many new ideas and features.

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.
