Pi

”“There is something for everyone in this book and everyone should read this book because it will be for some, a revelation that mathematics can be fun and beautiful, something they may not have realized during earlier encounters. Math teachers will find a host of ideas to enrich their instruction since Pi, as you know, comes up everywhere. This book is highly recommended and should provide a major step toward increasing the popularity of mathematics.”-Education Update “A joyful exploration…written in a conversational style reminiscent of children’s science books. The writing is clear and crisp and draws the reader into the author’s enthusiasm…I highly recommend [this book] to high school and college students and teachers of both. The book captures the excitement and fascination of pi and can serve as a starting point for more detailed discussion.”-Mathematics Teacher“I enjoyed reading the book…for its many applications, curiosities, and anecdotes.”-Science “Readers curious about pi could start here…Recommended.” -Choice

Alfred S. Posamentier is an American educator and a lead commentator on American math and science education, regularly contributing to The New York Times and other news publications. He has created original math and science curricula, emphasized the need for increased math and science funding, promulgated criteria by which to select math and science educators, advocated the importance of involving parents in K-12 math and science education, and provided myriad curricular solutions for teaching critical thinking in math.

Dr. Posamentier was a member of the New York State Education Commissioner’s Blue Ribbon Panel on the Math-A Regents Exams. He served on the Commissioner’s Mathematics Standards Committee, which redefined the Standards for New York State. And he served on the New York City schools’ Chancellor’s Math Advisory Panel.

Posamentier earned a Ph.D. in mathematics education from Fordham University (1973), a master’s degree in mathematics education from the City College of the City University of New York (1966) and an A.B. degree in mathematics from Hunter College of the City University of New York.

Ingmar Lehmann is retired from the mathematics faculty at Humboldt University in Berlin. For many years, he led the Berlin Mathematics Student Society for gifted secondary school students, an organization with which he is still closely engaged today.

He is the author of numerous mathematics texts in Germany and the coauthor with Alfred S. Posamentier of some other books, including The Secrets of Triangles, The Glorious Golden Ratio, Magnificent Mistakes in Mathematics, and The Fabulous Fibonacci Numbers.
