Publication Date: November 15, 2011
What exactly is the Golden Ratio? How was it discovered? Where is it found? These questions and more are thoroughly explained in this engaging tour of one of mathematics' most interesting phenomena. Veteran educators and prolific mathematics writers trace the appearance of the Golden Ratio throughout history and demonstrate a variety of ingenious techniques used to construct it and illustrate the many surprising geometric figures in which the Golden Ratio is embedded. Requiring no more than an elementary knowledge of geometry and algebra, the authors give readers a new appreciation of the indispensable qualities and inherent beauty of mathematics.
Alfred S. Posamentier (River Vale, NJ) is the dean of the School of Education and professor of mathematics education at Mercy College in Dobbs Ferry, NY. He has published over fifty books in the area of mathematics and mathematics education, including The Pythagorean Theorem; Math Charmers; and (with Ingmar Lehmann) The Glorious Golden Ratio; Mathematical Amazements and Surprises; The Fabulous Fibonacci Numbers; and Pi: A Biography of the World's Most Mysterious Number.
Ingmar Lehmann (Berlin, Germany) is on the mathematics faculty at Humboldt University in Berlin. He also heads the Berlin Mathematics Student Society for gifted secondary school students. A prolific author of books on mathematics and mathematics education, he is the coauthor with Alfred S. Posamentier of The Glorious Golden Ratio; Mathematical Amazements and Surprises; The Fabulous Fibonacci Numbers; and Pi: A Biography of the World's Most Mysterious Number.
"Beautiful geometric constructions abound, making browsing the book a pleasure. Valuable for all mathematics collections...highly recommended."
- Choice: Current Reviews for Academic Libraries
"Requiring no more than an elementary knowledge of geometry and algebra, The Glorious Golden Ratio will give all readers a new appreciation of the indispensable qualities and the inherent beauty of mathematics."
- Mathematical Review
"The reader of mathematical literature will feel at home in Posamentier's book. The work is sophisticated and serious, leaving the reader to reflect on the properties and nature of the iconic golden ratio."
- Sacramento/ San Francisco Book Review
"From relationships between the Golden Ratio and other famous number sets to appearances in nature, literature and technology, this provides a wide-ranging discussion that requires only a basic knowledge of geometry and algebra to prove inviting. College-level collections will welcome this discussion!"
