A reflection on the impact of being a lover of math

I picked this book up by chance and found that I couldn't put it down. I carried it everywhere I went in order to read more as soon as I could. This book was a reflection on the life of Paul Erdos but also to my great surprise on many other mathematicians. This book is a great way to discover how math has impacted and changed not only the mathematicians lives but ours from their discoveries.

A Good Look at a Great Mathematician

The story of Paul Erdos was fantastic and fascinating. To begin with, he had no home. His entire earthly belongings were in two suitcases; one held a few items of clothing, the other was full of mathematical papers which accompanied him as he traveled around the world going from one mathematics conference to another, pausing long enough only to deposit some works in an archive at the home of Ronald Graham and Fan Chung, a husband-and-wife team of remarkable mathematicians in their own right.Paul Erdos was known as the greatest of mathematical collaborators; he co-authored far more papers with other mathematicians than did anyone else. The extent of his collaborations with other matheamticians has given rise to what is now known as the 'Erdos number' which is simply this: If you co-authored a paper with Erdos you have an Erdos number of one, if you wrote a paper with someone who wrote a paper with Erdos, your Erdos number is two, and so forth and so on. As far as I know, the highest Erdos number is eight. Approximately five hundred mathematitians have an Erdos number of one, the number having an Erdos number of two or higher is well into the thousands; a compete listing is maintained by Jerry Grossman of Oakland University. Erdos had virtually his own language, to him the Unites States was 'Sam' (for Uncle Sam) and the Soviet Union was 'Joe' (for its long-time leader Joseph Stalin.) Women were 'bosses' and men were 'slaves'. A person 'died' when he or she ceased doing mathematics; when that same person actually expired, he or she 'left'.This book gives a good look at what goes on in the mind of a mathematician. While there is plenty of mathematics in this volume, the book is written in such a manner as to be understandable by anyone with a high-school education; little or no specialized training in mathematics is required to reap full enjoyment from it. Even if you are unfamiliar with such concepts as Mersenne or Fermat primes or repunits, this book will be both entertaining and enlightening. I believe this book is a better 'read' than Sylvia Nasar's "A Beautiful Mind;" the major focus of the latter book was not so much about mathematics as it was about schizophrenia.There is no doubt that Paul Erdos was one of the most extraordinary people you could ever wast to meet. This work belongs in the library of any person who may be even the least bit curious about what goes on on the mind of an extraordinary human being.

Affectionate and balanced portrait of a mathematical genius

I very much enjoyed this biography (Hoffman calls it "in large part a work of oral history") of the legendary Hungarian mathematician, Paul Erdös. Hoffman's relaxed style with his attention to detail and concrete expression makes it a pleasure to read. You don't need to know any mathematics. Hoffman mentions the math and occasionally goes lightly into it, but for the most part the focus is on the eccentric and loveable mathematician himself and his many friends and collaborators. In fact, the title is somewhat ironic since Erdös was very much a people person, a man who loved and was loved by others. It is only in the case of "romantic" love that Erdös loved only numbers.By the way, Hoffman does indeed go into Erdös's sex life in a completely tasteful and PG-13 sort of way. He was a man who dearly loved his mother and children but practiced a deep and abiding celibacy all his life. His friends made many jokes about his uneasiness with "bosses" (his pet name for women) and once made a bet with him that he could not go to a burlesque show. He did however, but took off his glasses so he couldn't see anything.Erdös was a pure mathematician, a child prodigy who fell in love with numbers at an early age and never lost his love while wandering over the entire globe searching for collaborators. He was himself a caricature of the absent-minded professor, a man who asked others to tie his shoes for him, a man who could not drive, who worked nineteen hours at day at mathematics, often calling his friends up at four in the morning to share an insight. He paid no attention to his appearance, cared nothing for literature, the arts, sports, etc., only for his beloved math. He had a way with children and an ability to impose on his friends, often arriving unannounced at their houses and staying for days or weeks at a time. He freely gave away his money to any number of charities, and sometimes to outright strangers on a whim. He cared nothing for worldly goods. He didn't even like applied mathematics, referring to colleagues who had gone that route, as being "dead." Indeed, only children and pure mathematics delighted him.There's a child-like simplicity to the man that charms us. Hoffman's book reflects this as a kind of fairy tale life lived in delight in spite of all the horror going on in the world. There is a pristine beauty to living one's life so incredibly focused on one thing. In a sense it is like an addiction and in another it is like an all-consuming love. It is the kind of life few of us could ever live (or would want to live), but it is the kind of life we can admire and read about with pleasure.Hoffman sometimes slips away from Erdös to write about his family and friends, especially about Ronald Graham, Erdös's long-time friend and collaborator, a very interesting man himself, a world class juggler and a practical as well as theoretical mathematician. Hoffman recalls some Hungarian history, some Cold War history, and relates anec

What a biography should be

Paul Erdos, a giant of twnetieth century mathematics, takes center stage in this biography which discusses the extent of both his brilliance and eccentricities. This is a man who made up his own language, roamed the world to discuss mathematical theory, befriended and frustrated his hosts and collabortators, and in is universally remembered as a loving genius. The book itself is a series of vignettes about Erdos's life woven together with explanations of numberous mathematical problems and theories, as well as stories of other math legends. It is very inclusive of the Erdos's predecessors as well as contemporaries, and shows the evolution of mathematics, within the larger context of a biography.I loved this book, mainly because of Erdos, who was a wonderful character. I was a poor math student in school, but Hoffman's descriptions made these incredibly complex ideas that Erdos played with understandable and interesting. Also, I learned a lot about the field of mathematics, mathematicians, and about passion. These men and women devote their lives to theorems that may never have any real appication, but they do it because of a love for the subject. It was facsinating and inspiring throughout, and a wonderful book for those who want a good story, great characters, and an understandable lesson in math.

Inspiring peek at an exceptional mathematician

This book should be required reading for anyone who is currently studying mathematics, but I would also highly recommend it for anyone remotely intrigued by the magic of numbers. As a math major I have at times grown weary of slogging through theorem after theorem, but I picked up Hoffman's book for a little summer reading, and was immediately captivated. My awe of the beauty of mathematics was totally resuscitated from the third year slump to which it had fallen victim. I was at turns amused, educated, inspired and touched. Hoffman deftly interlaces anecdotes about Paul Erdos with tales of some of the finest mathematical minds, and many of their most important discoveries. This is not just a mere biography of a great mathematician, and those who approach it as such will miss the whole point. It is not only about Paul Erdos but about "the search for mathematical truth", the tragedy of failure as well as the ecstasy of the perfect proof, "straight from the Book". Mathematics was Erdos' life. To separate him from the body of knowledge that he embraced and spent his life furthering would be a complete disservice, and would give only a fraction of his story.

A biography that mostly isn't one

Being something of a 'lapsed' mathematician (long ago math major, long unused), I'm always interested in books that involve numbers and people who love numbers. I'm usually not fond of biographies, but I'd heard good things about this one and decided to give it a try. To my surprise and joy, it turned out to be more about numbers and math in general, than about those irritating details of a person's life that usually get in the way of a good read. I agree with one of the earlier reviews here that trying to write an entire book devoted just to Paul Erdos would probably have been futile -- his entire life was numbers. This book opens doors for people who aren't familiar with the various theories and offers some 'math surprises' for those of us who were familiar with math in a former life. I'm still puzzling over the tiling result. (Sorry, you'll have to read the book to find out what it was.) Loved it. Highly recommend it. Have so far purchased two copies as gifts and will likely purchase at least two more (I have a lot of math-oriented friends).
