The Glorious Golden Ratioby Alfred S. Posamentier
Synopses & Reviews
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. The authors trace the appearance of the Golden Ratio throughout history, 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.
Book News Annotation:
Having teamed up before for books on Fibonacci numbers and Pi, Posamentier (mathematics education, Mercy College, Dobbs Ferry, New York) and Lehmann (mathematics, Humboldt U., Berlin) explore the features and implications of a ratio that has permeated art and architecture since prehistoric times. High school algebra and geometry should be enough mathematical background to follow the discussion. The topics include the golden ratio in history, the numerical value of the golden ratio and its properties, unexpected appearances, the plant kingdom, and fractals.
