The Man Who Loved Only Numbers: The Story of Paul Erdös and the Search for Mathematical Truth

The biography of a mathematical genius. Paul Erdos was the most prolific pure mathematician in history and, arguably, the strangest too. ’A mathematical genius of the first order, Paul Erdos was totally obsessed with his subject – he thought and wrote mathematics for nineteen hours a day until he died. He travelled constantly, living out of a plastic bag and had no interest in food, sex, companionship, art – all that is usually indispensible to a human life. Paul Hoffman, in this marvellous biography, gives us a vivid and strangely moving portrait of this singular creature, one that brings out not only Erdos’s genius and his oddness, but his warmth and sense of fun, the joyfulness of his strange life.’ Oliver Sacks For six decades Erdos had no job, no hobbies, no wife, no home; he never learnt to cook, do laundry, drive a car and died a virgin. Instead he travelled the world with his mother in tow, arriving at the doorstep of esteemed mathematicians declaring ‘My brain is open’. He travelled until his death at 83, racing across four continents to prove as many theorems as possible, fuelled by a diet of espresso and amphetamines. With more than 1,500 papers written or co-written, a daily routine of 19 hours of mathematics a day, seven days a week, Paul Erdos was one of the most extraordinary thinkers of our times.

About the Author :
Paul Hoffman is the publisher of Encyclopaedia Britannica. He is the host of the five-part PBS series Great Minds of Science and a frequent correspondent on television shows such as CBS, This Morning and The News Hour with Jim Lehrer. For ten years, Hoffman was the president and editor-in-chief of Discover magazine. He is the author of ten books including Archimedes’ Revenge. He lives in Chicago, Illinois and Woodstock, New York. Paul Hoffman first met Erdós in 1986 and interviewd him over the last ten years of his life, even following him on his mathematical sojourns. Hoffman’s 1987 profile of Erdós in the Atlantic Monthly won the National Magazine Award for feature writing, the most prestigious award in American magazine publishing. In their citation the judges proclaimed it ‘a minor classic, written with amazing clarity and wit’.

Review :
"Hoffman's playful, plainspoken and often hilarious biography of a monkish, impish, generous genius is purest pleasure." Mail on Sunday "Paul Hoffman's wittily articulated life of the mathematical genius Paul Erdos opens a door to a sunlit upland of pure logic, populated by bungee-bouncing, bearded maniacs and absurdly intelligent men who never learnt to tie their own shoelaces...Anyone with an interest in the science of numbers should read this." Observer "The Man Who Loved Only Numbers is one of the most accessible and engaging introductions to the world of pure mathematics you are ever likely to come across." Graham Farmelo, Sunday Telegraph "A wonderful, playful, insightful life of this century's most unusual mathematician." Ian Stewart, Independent
