Book of the Week
I can’t pass up mention of a new book, Beyond the Quadratic Formula, which appeared for sale just three days ago at the eBooks Store of the Mathematical Association of America. I understand that a print version will be available in July. Here’s the blurb:
The quadratic formula for the solution of quadratic equations was discovered independently by scholars in many ancient cultures and is familiar to everyone. Less well known are formulas for solutions of cubic and quartic equations whose discovery was the high point of 16th century mathematics. Their study forms the heart of this book, as part of the broader theme that a polynomial’s coefficients can be used to obtain detailed information on its roots. A closing chapter offers glimpses into the theory of higher-degree polynomials, concluding with a proof of the fundamental theorem of algebra. The book also includes historical sections designed to reveal key discoveries in the study of polynomial equations as milestones in intellectual history across cultures.
Could be interesting. I might buy a copy or two.
