The Square Root of 2

Using no more than the most basic algebra and geometry, Flannery (Cork Institute of Technology, Ireland) manages to convey not only why irrational numbers are fascinating, but how the whole enterprise of mathematical thinking is imaginative, intriguing, and engaging. A startlingly original and informative dialog, this book is a one-of-a-kind introduction to the pleasure and playful beauty of mathematical thinking.
