title: The Circle: A Mathematical Exploration beyond the Line
author: Alfred S. Posamentier
description: A fascinating book taking the reader full circle through the circles baffling properties.As a layperson I was fascinated by the authors subtle way of leading me through complex mathematical formulasall connected with the circle but never circular.A cleverly written book offering new perspectives for the nonexperts.<br /><br />Arthur Mettinger, professor, University of Vienna, Department of English and American Studies; and academic president, FH Campus Wien University of Applied Sciences<br /><br />This book should be read by everyone who thinks math and geometry are difficult or boring. The authors, leading mathematicians themselves, have taken the topic of circles and shown us how fascinatingmagic, indeedand central to our experience of the world circles are. Posamentier and Geretschlger have explored the world of circles and their many applications in everyday life as well as in geometry, in a way that the most nervous layperson can understand and enjoy. I for one will never look at architecture or art in the same way after reading this book. I especially commend it to every teacher or confused student of mathematics.<br /> <br /> Baroness Pauline Perry, former president of Lucy Cavendish College, Cambridge University<br /> <br /> After reading this wonderful book, which helped me to recall my early memories of the geometry of circles, I was absolutely enchanted by the wonderful relationships involving circlesas well as their constructions and their appearances in our culture and on the spherethat we should have been exposed to in our school days but never were! This is the book that all who have even the slightest interest in geometry will love, to have their knowledge of circles enriched.Great book!<br /> <br /> Charlotte Frank, PhD, senior advisor, McGraw-Hill Education; former director of curriculum and instruction, New York City Board of Education; and former regent, University of the State of New York<br /> <br /> This is a remarkable addition to the geometry literature, giving a very incisive new insight into the role of the circle and how it relates to the line and other geometrical forms. Whatever your background, this is sure to help you reinforce your comprehension of all things geometric.<br /> <br /> Peter Taylor (AO), emeritus professor, University of Canberra<br /> <br />Alfred S. Posamentier and Robert Geretschlger are a congenial mathematical author team; they are impressive not only for their superior content competence but also for their extraordinary talent to present mathematics to the general audience as a fascinating, enriching adventure. This book not only enhances the readers knowledge but also is remarkable for its modest tone and splendid style.<br /> <br /> Rudolf Taschner, professor of mathematics, Vienna University of Technology, and 2004 Austrian Scientist of the Year<br /> <br />This volume is a treasure trove on everything you want to know about circles. Starting from simple results in Euclidean geometry, it reaches far both in space and time, revisiting many famous historical problems and considering more modern topics such as inversive geometry and combinatorial geometry. . . . Afantastic collaboration between two noted mathematicians.<br /><br /> Andy Liu, Professor Emeritus, Department of Mathematical and Statistical Sciences, University of Alberta, and vice president, International Mathematics Tournament of the Towns
