"A lighthearted yet far-reaching look at the history of numbers and how we use them." — Publishers Weekly Have you ever wondered what humans did before numbers existed? How they organized their lives, traded goods, or kept track of their treasures? What would your life be like without them? Numbers began as simple representations of everyday things, but mathematics rapidly took on a life of its own, occupying a parallel virtual world. In Are Numbers Real?, Brian Clegg explores the way that math has become more and more detached from reality, and yet despite this is driving the development of modern physics. From devising a new counting system based on goats, through the weird and wonderful mathematics of imaginary numbers and infinity, to the debate over whether mathematics has too much influence on the direction of science, this fascinating and accessible book opens the reader's eyes to the hidden reality of the strange yet familiar entities that are numbers. Praise for Are Numbers Real? "A compact, very readable, and highly entertaining history of the development and use of mathematics to answer the important practical questions involved in advancing civilization... a superb introduction to mathematics, science, and that branch of philosophy devoted to exploring the nature of reality." —Dr. James Stein, California State University, Long Beach "Clegg tackles a very deep question in his usual way; with clarity, wit and a wonderfully clear narrative writing style. For me, numbers are like natural language: They obviously don't exist in a physical sense—you cannot trip over the number 2 in the street—yet numbers are at the heart of understanding the universe. Clegg covers a wide variety of subjects to seek out the truth of the matter in an engaging and hugely accessible way. I personally couldn't put it down." —Dr. Peet Morris, University of Oxford
