    The book is about the life story of John Forbes Nash - a mathematical genius and inventor of a theory of rational behaviour for which he was awarded a Nobel Prize in 1994. Presenting a characterization of schyzophrenia, the author helps in informing the reader about the circumstances under which a spontaneous recovery from his dementing and degenerative disease believed to be so rare, became a possibility for John Nash. Finally, the story of Nobel Prize winner John Forbes Nash, Jr. proves that psychiatrists are wrong about schyzophrenia being a brain disease like Alzheimers and Parkinson's.

    I read very few biographies, so I have trouble evaluating this within its field. That said, I found it fascinating, but a bit drier than I typically like my (recreational) nonfiction.But it is a fascinating and disturbing story. Nash lived (still is living, I guess) a really complicated life, even aside from his illness. Like many geniuses, he was a "difficult" personality. (He apparently used to stand on the table in the middle of Princeton's math department grad student meetings and put down anybody who might challenge his intellect.) This naturally caused him certain social frictions, but he was apparently forgiven a lot because of his genius. And then, when his schizophrenia struck, he was protected further by colleagues who respected him.And there was a lot of protecting going on. For example, when he pushed his pregnant wife down the stairs. (Bits that they leave out of shallow, fantasized Hollywood treatments.) Or that he cheated on her. Or the fact that he treated his son like a pariah. Some of this is entangled with his illness, of course, but not all. And a lot of the looking the other way happened before his illness was public knowledge. It makes me reflect on the structure of society in general, and academia specifically, and what we regard as sufficient excuse for bad behavior. (I had a long rant on scientific academia here, but I'm too tired to make it coherently now, and this really isn't the best venue.)As a math geek, I wish there had been a bit more about his math itself. It's difficult, I guess, because most of what he worked on was extremely abstruse stuff -- even to someone who has studied a reasonable amount of (mostly applied) math. I understand Nash equilibria, but, interestingly enough, even though he won the Nobel for this idea, he and the mathematical community generally felt that this was far from his most interesting and important contribution. And that's probably the most accessible thing he worked on. (Which is probably why it was able to become important in economics circles.) His other works are so involved that I have trouble parsing the statement of the theorems, let alone the proofs.But really, this is the story of his life. Like all of us, he lived a complicated, difficult life. More complicated and difficult than many, but still a very human life.

    More reviews at The Story Within The StoryAt first glance, a biography of a mathematician would seem to make for a read dryer than the Sahara. However, John Nash is no ordinary mathematician and Sylvia Nasar is no ordinary biographer. In her capable hands, the life of John Nash comes to life…in all of its brilliant, dark, pessimistic, extraordinary, callous wonder. John Forbes Nash, Jr. is a mathematical genius whose extraordinary mind developed the structure for what became known as Game Theory – revolutionizing both mathematics and economics in the second half of the twentieth century. The power of his theories culminated with him being awarded the Nobel Prize for Economics nearly fifty years after his groundbreaking work began. But it came at a heavy price. By the age of thirty, Nash was suffering from his first bouts of paranoid schizophrenia, a disease he would suffer with for three decades. He was institutionalized by his family on several occasions and left for dead by most of the mathematics community. Left to wander the campus of Princeton University as a “ghost” and a “crazy man,” Nash did the unthinkable – he began recovering from a disease that there was thought to be no recovery from. He even begin to work on mathematics research again. It was a recovery that physiatrists thought was impossible.“I've made the most important discovery of my life. It's only in the mysterious equation of love that any logic or reasons can be found.”A Beautiful Mind is really not about mathematics, but about what it means to be labeled “gifted,” “different” or “sick.” It is about how society treats people who are unusual and how few answers there are for what goes on between someone’s ears. It is also about John’s wife Alicia, who set aside her own desires to try to guide John through a world that had become hostile to him.Ultimately, Sylvia Nasar succeeds with A Beautiful Mind because she leaves out most of the heavy-handed mathematics and focuses on who John Nash is and what his life represents. Make no mistake, John Nash not a lovable person. He is rude, thoughtless, self-centered and egotistical – all the things we don’t like in a person. His genius is both a gift and a curse. Yet, we cheer for him the whole way because there is an innocence about him; a childlike quality of someone who doesn’t quite understand other people but has to function within society none-the-less. And it is a society of the 1950s and 1960s with little understanding or tolerance for mental illness. His story also gives us hope that no matter how hopeless a person’s situation may seem, here is an example of someone who was able to climb out of that hole and rejoin life and be happy again. That is what makes John Nash’s story so important – A Beautiful Mind demonstrates that anyone’s life can be turned around. It demonstrates hope. It demonstrates redemption. It is a story well worth your time.

    The book conveys a convincing portrayal of mental illness; but, it is unpleasant to read. I found that I didn't enjoy spending so much time with a person who, in addition to being a genius, and mentally ill, was basically a creep. The movie was better - mainly because the screenplay converted Nash into a more likeable guy (helped to be played by Russell Crow). If you haven't read the book or seen the movie - I recommend the latter. But keep in mind it's not a terribly truthful portrayal.

    "'How could you,' Mackey asked, 'how could you, a mathematician, a man devoted to reason and logical proof. . . how could you believe that extra terrestrials are sending you messages? How could you believe that you are being recruited by aliens from outer space to save the world? How could you . . .?' "Nash looked up at last and fixed Mackey with an unblinking stare as cool and dispassionate as that of any bird or snake. 'Because,' Nash said slowly in his soft, reasonable southern drawl, as if talking to himself, 'the ideas I had about supernatural beings came to me the same way that my mathematical ideas did. So I took them seriously.'"A Beautiful Mind by Sylvia Nasar is the biography of John Forbes Nash. Nash was brilliant. (The movie was terrific, but often bore little resemblance to reality.) At twenty-one he had invented a theory of modern human behavior and his contributions to game theory would ultimately win him a Nobel Prize. As a young professor he solved some mathematical problems deemed "impossible" by other mathematicians. He also became insane. This most fascinating book is the story of his descent into schizophrenia and his sudden remission at age sixty-two.Nash had that spark of genius reserved for the extraordinary few. He could visualize answers to problems that baffled others, often working out proofs later. He worked and learned not by absorbing what others had already accomplished but by rediscovering the concepts on his own. He was "compulsively rational," and envied the emotionless, considering thinking machines superior to humans. He remained aloof from the mundane and was described by his contemporaries as "queer," "spooky," and "isolated." Ironically, he was to revolutionize the theories of social cooperation and conflict. Unlike Von Neumann who had focused on the group, Nash, in his twenty-seven-page dissertation thesis proposed a theory for game "in which there was a possibility of mutual gain. His insight was that the game [economics:] would be solved when every player independently chose his best responses to the other player's best strategies. . . a decentralized decision-making process could, in fact, be coherent."Princeton probably deserves the Nobel medal as much as anyone for sticking with the genius and putting up with his bizarre behavior as does his family who often sacrificed a great deal in their efforts to help him. Whether an "ordinary" person would have received such special care is perhaps another issue.What is truly ironic is that Nash's son suffers from the same condition as his father, but despite advances in pharmaceutical treatment for schizophrenia, his son has not displayed the signs of remission that brought his father back.

    A Beautiful Mind is one of those books that I loved so much, and learned so much from reading that I've yet to actually review it. However, in light of the news that the man behind the eponymous mind,John Forbes Nash Jr.,is no longer with us I thought I'd at least take the time to recommend the book, if not to explain why.

    I would have never gotten through this book if it wasn't an audiobook. Author Sylvia Nasar presented a comprehensive narrative of John Forbes Nash's life. Unfortunately, she was absent from school the days they taught about engaging your audience, limiting your topic, and just about every other skill related to literature. She is no doubt a wonderful researcher, but includes details so small as to call into question her own sanity, let alone the sanity of her subject.This book was a lot like watching someone else's home movies. To them, they are interesting; to everyone else they are a drudgery. For about the first 49 chapters you could literally skip all the odd chapters and not really miss anything.There were a few moments of interesting detail, mostly surrounding the Nobel Prize and applications of Nash's work. Also, I found the details of Princeton in the 50's and 60's interesting since I live near there. Otherwise, it was dull.Though I usually like Blackstone Audio's production of books, the narration of this one by Anna Fields, was below their standards. The narrator's voice was so expressionless that she seemingly started new chapters mid-sentence.This is one of those rare cases where the movie was much better than the book. In fact, if the titles weren't the same I'd be hard-pressed to tell you that they were based on the same story.A true disappointment. I should have listened to the wisdom of my older sister and skipped this one. That is 17 hours of my life that I'll never get back.

    It seems to be a commonly held belief that genius often goes hand-in-hand with mental illness. I've often wondered if this is actually the case or whether it's just that most people have never heard of most genius level intellects that aren't afflicted in this way. How many of us could honestly say we'd ever have heard of John Nash if it weren't for his prolonged battle with schizophrenia (if 'battle' is even the right word)?I admit that I'd not heard of him until my wife recommended the movie to me after watching it with friends. I quickly bought it and loved it (I know which side my bread is buttered, folks) and this lead me to read the book the movie is based on.Having now finished the book, I have to say that it's made me reappraise the film. While I'm sure I'd still enjoy the movie, I now see that it is an extremely idealised version of Nash's life. It has left out large chunks of the less sympathetic aspects of the man's personality. It's almost impossible to say how much of Nash's (how to put this?) dickish behaviour was due to his as-yet-undiagnosed schizophrenia but it is clear (to this reader, anyway) that the man was a rather unlikeable individual long before he became ill.I don't, however, only want to read about people I'd like to have a drink with and, despite the rather unsavoury aspects of Nash's character, this is undeniably a fascinating book and I'm very glad I read it. It manages to be a 'warts-and-all' autobiography without ever stooping to sensationalism and remains respectful of its subject even while recounting some of his worst facets. I recommend it to anybody who has seen the movie version that would like to know the truth behind the Hollywood fairytale.It's also made me want to read more about game theory...

    This biography was the basis for the popular film "A Beautiful Mind" a few years ago. It's the fascinating story of an arrogant young mathematician who began his career with genius-level work in mathetmatics, succumbed to paranoid schizophrenia in his thirties, and ultimately experienced a remission in the late 80s and was awarded the Nobel Prize for his early work in game theory.Reading about Nash's early life and the beginning of his career, I couldn't help but notice that he was always rather an odd duck, even before he became delusional and was diagnosed as schizophrenic. I'm inclined to think that if he were a child now, it's fairly likely he would be diagnosed as having Asperger's or something similar, but that's just my uneducated opinion. His way of relating to the world was always sufficiently different that it took a long time for many of his colleagues to realize that his eccentricities had morphed into delusions. He was a genius, he was expected to behave oddly, and in some ways this both served as a measure of protection for him, and also may have prevented him from getting help earlier.I have to admit that I actually really disliked John Nash for a lot of the book. Even when he was sane, he was arrogant, self-absorbed, and unkind. He must have had some good qualities, though, other than his genius, because what really saved him in the end was the willingness of his friends and family to stand by him and try to help him. Again and again during his illness, his colleagues arranged work for him, smoothed over scandals caused by his odd behavior, and assisted his wife and mother in providing him with care. At times, his friends were almost too caring -- not having the same intimate contact with Nash that his wife Alice did, many of them believed he was not as ill as he actually was, and were very upset when he was involuntarily committed. The many points of view Nasar provides really bring home what it's like when someone succumbs to mental illness, and the way it affects just about everyone the person comes into contact with, like ripples in a pond.Nash's return to normality after years of delusional behavior is still something of a mystery to neuroscientists. This is not something that often happens in schizophrenic patients, which led some to posit that Nash may not have been schizophrenic, after all. Yet his behavior and experiences are much more consistent with schizophrenia than with any of the other illnesses, like biopolar disorder, that have been suggested. This leads to the conclusion that Nash is one of the lucky few who experience a near-complete remission after years of illness. I'd definitely recommend this biography to anyone with an interest in mathematics, mental illness, or who just likes a well-written biography.

    I was thinking of this book again because of the deaths of John and Alicia Nash. At this remove, I cannot remember any details. We had this book on audio during a car trip. In 2002 the medium may have been tape. We either had the book as well, or, if not, I was picking my husband's brain on the story's mathematical aspects. The story was well told, very moving; the aspects relating to his schizophrenia passed muster with me. Later we saw the film, and I was appalled; thought the schizophrenia had been reworked to fit public expectations (to conform to some meme). In the news article I read, all references were to the film; it was as though there had never been a book. Again, it was very good; although the details have faded, it possibly was in a class with Simon Winchester's The Professor and the Madman: A Tale of Murder, Insanity and the Making of the Oxford English Dictionary

    Update: 24/05/15Noble Laureate, Genius Mathematician John Nash is no longer with us. He is killed in a car accident along with his wife.http://www.nbcnews.com/news/us-news/j...****This is the story of John Forbes Nash, Jr. It is a story about the mystery of the human mind, in three acts:1. GENIUS: Perhaps John Nash was the greatest mathematical genius ever born in his times. He grew up as a child who lacked social skills (which his parents feared the most), days he locked himself up in dark room with books alone, has no close friends etc., all he got was his mother, his sister and his mathematical books. Soon after he grew up into a young man who took up Secret-code breaking jobs at RAND, who gave mind blowing seminars at Princeton & MIT and who invented theories (at Carnegie) which no one could possibly think of. But what author irritates you with in this genius tale is jumping into long and unnecessary back stories of people who inspired John or made friends with or simply he met and long mathematical equations/jargon which I never understood (which proved life achievement otherwise to John of course). As a person John was never liked by anyone but everyone approved that he is a genius. 2. MADNESS: Perhaps this is the worst phase that any human being could get into leave alone John. He often flew off from country alone (only wife was allowed to see him), approached NATO countless times as a refugee. He met horrible treatment days at hospitals (to cope with his delusions). What made his life worse were conflicts between his mistress (who is bearing his son now) and his wife, Alicia Nash who is stubborn enough not to give up on John and stay with him despite of his dangerous conduct towards others and to himself (To me she was more inspiring through-out than her husband). In eye’s blink John lost 25 years which he always regretted. Finally, his wife gave up on him too. Now John is all alone and he has his madness in its peaks.3. REAWAKENING: I count this book as inspiring not because it’s about a mathematician who solved problems in a snap which took lifetime to his colleagues just to understand them, but because of his determination to deal with his delusions, his will to cope with his illness, his awareness to revitalize his relations with people (who considered him as mad by the time) around him and his remarriage with Alicia Nash again and his reawakening state as a whole (Perhaps this is the best part of the whole book). No wonder people fought for John to nominate him at the Noble in spite of his illness and awkward behavior (his nomination alone can jeopardize the status of the Noble prize and its history you see, this triggered few people at Noble committee to oppose his nomination) This is the story of John Forbes Nash, Jr. It is a story about the mystery of the human mind. Inspiring, but not perfect in writing (more academic, unnecessarily long and too explanatory at times). 4/5 to this Pulitzer prize nominated, Oscar winning film turned inspiring biography.

    When it comes to geniuses, a few archetypes generally come to mind. They're often characterized as under appreciated geeks with hearts of gold (think the entire cast of Revenge of the Nerds) or as slightly spaced out but cuddly old men (think Einstein). Or they're quixotic coyotes forever trying to nab that pesky road runner. In any case, the word "noble" probably applies, at some level, to most conceptions of the intellectually gifted.This is not true of John Nash, the subject of the biography A Beautiful Mind. He's a total a-hole.In fact, judged by the contents of the quite detailed book, Nash is a grade A jerk, the kind of guy you'd rather punch in the teeth than appreciate or get to know. Here's a guy who constantly belittled those around him, refused to support his illegitimate son in any way, demeaned his wife, harbored jealous grudges against those few who bettered him, periodically erupted in violence when thwarted, and was generally contemptuous of you or anyone like you. Really, his ego, misogyny, racism, arrogance and general prickishness knew no bounds.Thing is, the same could be said for his intellect and his ambition. He was apparently one of the most brilliant mathematicians of the last century, and his character is made more interesting by the fact that he often went about solving mathematical problems in unique and revolutionary ways that broke new grounds in various fields. I can't imagine what it would be like to be that smart, but it's fun to try. The author of his biography, Sylvia Nasar, does a great job of making his life's story interesting, even before we get to the part where the brilliant mathematician tragically plunges into the dim depths of schizophrenia, only to slowly awaken years later just in time to receive a long-overdue Nobel prize. Though age and mental illness have mellowed him greatly, Nash was an interesting character all through his life (and he is, in fact, still alive). Nasar makes this all accessible by stitching together many fascinating episodes into one whole narrative, repeatedly using themes of "genius, madness, and awakening."Parenthetically, this book is much more complete than the 2001 movie of the same name. In fact, there's really very little overlap between the two. The movie contrives scenes for the sake of drama and totally glosses over critical aspects of Nash's life, such as his bisexuality, the ignoble way he treated his first family (including an illegitmate son) in Boston, or even that whole "math" thing he was so good at. Also, Nash's general "jerk-ishness" is really toned down in the movie, despite being on center stage in the book. And that whole "imaginary best friend/roomate" thing from the book? Apparently never really happened in the book or real life, dramatic as the reveal was in the movie. So even if you've seen the movie, I recommend the book; there's lots more to learn. The only downside of the book relative to the movie is the conspicuous absence of Jennifer Connelly.

    كانت "أوفيليا" تقول على عقل هاملت : يا لهذا العقل الجميل المضيع!. لكن اليشيا لارد فى هذه الحكاية ساعدت ناش على أن يفلت من الضياع، لتكون تلك قصة "عقل جميل". تخرج جون فوربس ناش من جامعة "برينستون". ثم تم تعينه فى معهد "ماساتشوستس للتكنولوجيا" هذا المعهد الموجود بمدينة كامبريدج بولاية ماساتشوستس . كان ناش يدرس فصل "التفاضل والتكامل"، وكتب فى أحد الأيام مسألة حسابية لطلابه متحديا إياهم أن يقوموا بحلها. وكان أن حضرت تلميذته "اليشيا" لمناقشته حول تلك المسألة. أثناء المناقشة نظر إلى عينيها ووجد الإصرار والشجاعة والإجلال لهذا الاستاذ، ووجدت هى فى عينيه الإحترام والعبقرية والإعجاب.. ووقع الإثنان فى حب بعضهما فورا، وتزوجا وأنجبا طفلا واحدا. ولد ناش فى 1928. عمل فى مكتب البريد وكان يقوم بالتجارب العلمية منذ صغره. وبسبب غرابة تصرفاته كان يعانى من رفض وأحيانا من تهكم المحيطين به، وما كان منه إلا أن يحول هذا الرفض إلى تعمق فى دراسته، وكانت تلك فرصة طيبة ليبحث عن ونس ومحبة؛ وكانت الرياضيات. حصل على الدكتوارة عام 1950 ببحثه الذى قدمه عن موضوع: الألعاب غير التعاونية. فى عام 1958 بدأت أعراض الانفصام. وفى عام 1959 تم تشخيص حالته بأنها:انفصام فى الشخصية ارتيابي مع اكتئاب بسيط وقلة التقدير للذات. وظل العقل ضائعا لوقت طويل فكان يخرج من المستشفى ليعود إليها مرة ثانية، وهكذا ظل حتى عام 1970 حيث توقف بارادته عن تناول أدويته وتعافى بعدها بالتدريج. لقد عانت طوال هذه الفترة الكبيرة زوجته من الانفصام، وعلاجه الذى أثر على علاقتهم الجنسية، والأسوء بالطبع تأثير العلاج على عقله، ومحاولته قتل ابنه الصغير، وتوقفه عن العمل لفترة كبيرة.. لكنها مع ذلك خاطرت حتى بحياتها للبقاء بجواره؛ لهذا هو لم يكن يجاملها حين قال: إنها كل الأسباب.أما نظرية الألعاب ببساطة والتى حصل ناش على جائزة نوبل للاقتصاد بسبب بحوثه واسهاماته فيها، فهى تحليل رياضى لحالات المكسب والخسارة، بمعنى تحليل لكل المعطيات الموجودة واختيار أفضلها فى لحظة التحليل. فاللعبة معناها موقف يجب اختياره من قبل أحد اللاعبين فى دوره، وهذه النظرية تساعدنا فى اختيار أفضل الحلول. وكلمة اللعبة تعنى فى هذه الدراسات (مشكلة رياضية ما يحاول العلم حلها). كان الموقف الذى اختارته اليشيا لارد هو أفضل الحلول بالنسبة لها، لو استخدمنا ناش، ولولا هذا الموقف لضاع "العقل الجميل". وتلك هى الحكاية ببساطة: نحن نعيش لنتدرب على اختيار أفضل الحلول فى لعبة الحياة، قل لى ما هو "اختيارك" أقل لك من أنت.بمناسبة نوبل، حصل ناش على الجائزة بسبب اسهامه الهام..إنه عالم رياضيات مهم طور نظرية للألعاب. هو دائما يؤمن بالأرقام وبالمنطق وبالسببية، وأود أن أكتب عن نظريته فى الألعاب بعد أن أنتهى من الكتاب، لكن الكتاب يحكى قصة حياة عالم فصامى وعبقرى.. وقد واصل حياته واسهاماته بسبب الحب! قال أمام الحضور لزوجته: أنت السبب، أنت كل الأسباب. كيف ذلك، تلك هى الحكاية الكبرى لهذا الكتاب.. Nash: Thank you. I've always believed in numbers; and the equations and logics that lead to reason. But after a lifetime of such pursuits, I ask, "What truly is logic? Who decides reason?" My quest has taken me through the physical, the metaphysical, the delusional -- and back. And I have made the most important discovery of my career, the most important discovery of my life: It is only in the mysterious equations of love that any logic or reasons can be found. I'm only here tonight because of you. (his wife, Alicia) You are the reason I am. You are all my reasons.

    I hardly finished part one of this book, it's too slow, filled with information and details even about John Nash's friends, the writer wanted to give us a full picture about John Nash's life and the people around him , but it seemed as if she wanted to have more pages filled.I liked the Idea of reading about a Mathematician but it was enough with the writer...John Nash is an interesting extraordinary man, I liked him through the documentary and the movie but not the novel. here are people stories living with schizophrenia https://youtu.be/-8RhNMRyKG0https://youtu.be/48YJMOcykvcI liked the movie (3.5 stars) and I watched a documentary about his life which was much better than the book itself. here is the link to the documentary about John Nash's life https://youtu.be/96Yb-w7427U

    This is one of those books where writing a review was so daunting that I didn't get to it right away . . . and so never got to it at all.But even though it has now been almost 3 years since I read it, I will try to come up with something. Because I see several friends who had it as "to-read" 3 years ago still have not read it, and they should!I enjoyed the movie that is loosely based on this book. But it takes a lot of liberties with the facts -- skipping Nash's early life altogether, ignoring/omitting his other son and other relationships, ignoring the fact that he and his wife were in fact divorced for many years. It also gets game theory really, really wrong. And the schizophrenic spy stuff came from the minds of the filmmakers. The movie took the real life of John Nash, trimmed off many of the unsightly bits, polished it up and added some color. Makes for a very good movie, but not an accurate biography.Sylvia Nassar gives us the real John Nash, in all his too-human glory, warts and all. She also gives a nice look at game theory which is very readable to the layperson. Her research and interviews were clearly exhaustive, and her presentation of Nash's life is well-written and multi-layered.If there is ever some reason for my biography to be written, I want Sylvia Nassar to do it.

    One cannot avoid the temptation of reading the book, after watching the movie; twice. The movie is excellent in the way it describes schizophrenia (a form of); better than many textbooks. One can actually see the mind at work of a math genius called Nash and even empathize with his afflictions; his inner struggle.From nearly the onset of the pathology, to its development, treatment and some recovery (by Nash's free will...and his wife's love), the movie tells a story through time: Nash while a student in college through his several jobs (even those imaginary!) till his final recognition as a Nobel-prize winner for his work in the mathematics and economics fields. Especially poignant are college and family scenes, for the awkwardness inherent to the pathology at stake: schizophrenia, its painful delusions and paranoia. Ron Howard did a great job/movie; Russell Crowe, a terrific acting part.The music of the film, by James Horner, has been a fantastic feat; how numbers and equations and solutions... and equilibrium ....became delicate, touching musical notes, one wonders.Well, if you're a mathematician, maybe you'll get curious about psychotherapy; if you're already a psychotherapist, math will tempt you in its beauty, as well.I owe the second view of the movie to my friend* at GR who had made a review of the book.Now, I can't let it go, listening to the movie soundtrack. The sum of a manin: https://www.theguardian.com/books/200...“Mathematicians are comparatively sane as a group. It is the people who study logic that are not so sane.” J. Nash"Nash was totally spooky. He wouldn’t look at you. He’d take a lot of time answering a question. If he thought the question was foolish he wouldn’t answer at all. He had no affect. It was mixture of pride and something else. He was so isolated but there really was underneath it all a warmth andappreciation of people”A fellow student at Princeton(The real Nash)But then, was he really a lousy character?in: https://www.theguardian.com/culture/2...*https://www.goodreads.com/review/show...

    Where I got the book: audiobook downloaded from Audible.I haven't had an Audible subscription for ages but I knew there were some books on there I hadn't listened to. I was surprised to find this one among them. Why, I wondered, had I picked a book about a mathematician I'd personally never heard of? By the time my youngest was in freshman year at high school I could no longer follow what she was doing in math. Actually, that was probably true in 8th grade. Ok, 7th grade. You get the picture? I'm not a mathematician.Well, I love surprises. I was spellbound by the story of John Nash, who as a young man emerged as one of the most talented mathematicians of his generation. The discussion of how mathematics, especially game theory, was used during the Cold War to plan strategies was beyond fascinating even though I didn't understand it 100%. And then as Nash drew closer to middle age, at the time when he should have been riding the top of the wave, his eccentricity degenerated into outright schizophrenia and cost him his job, his marriage and his rational mind.And THEN--I feel like one of those commercials, "Wait! There's more!"--after years spent in asylums he somehow managed to emerge from insanity and THEN, something like 40 years after he'd done the work, he was awarded a Nobel Prize for his contribution to game theory. (view spoiler)[By the end of the book he is living in a fragile balance with his ex-wife, still seeing his mathematical friends and caring for a son with schizophrenia. And, most striking of all, he is a much nicer person after his harrowing experience with insanity than he was as an arrogant wunderkind. (hide spoiler)] Nasar provides a very complete, warts-and-all picture of a human thinking machine.This was the abridged version, which was a pity. One day I'll seek out the full version and read it, or listen to it, again. The narrator, by the way, one Edward Hermann, was one of the best I've heard recently; an unremarkable voice in a way but a reading that was as smooth as silk with absolutely NO annoying mannerisms of speech.

    Update of 7/2017: I recently learned that John Nash had a letter of recommendation written by Herbert Simon, he of the Nobel Prize deconstructing Rational Model Theory. Who knows, maybe Nash and Simon were working on the same problems in some way. But it appears that Nash was already of two minds in early university days: his own and Simon's. Then again, have you ever noticed how many bank clerks, librarians, grammar school teachers, and accountants become paranoid, tinpot dictators somehow?Original review:John Nash won his Nobel for economic models based on game theory. This was the popular attempt to reduce human enterprises to closed-world, zero-sum rational (logical?) models. Subsequent economists have won Nobels for saying that this is simply impossible.I'm not any sort of expert, but it's just possible that paranoia builds up in a person who tries to build castles of sand on a sand bar. Counter-intuitively, the book suggests he calmed himself by working with computers.

    This was one of my favorite reads of 2017. I never thought I would be so interested in details about math theorems, math colleges, and history of math. Apart from the rich setting, I quite enjoyed learning about Nash, and I learned so much more about him than from watching the movie based on this biography (naturally).Anyways, I love this book so so much. It has been 4 months since I read it, and I still feel fuzzy and warm inside when I spot it on my shelf ♥

    A seguito dell’assegnazione nel 1994 del premio in memoria di Alfred Nobel (istituito dalla Banca di Svezia) a John Forbes Nash Jr, la giornalista del New York Times Sylvia Nasar fu incaricata di redigere alcuni articoli dedicati al matematico: le singolari e drammatiche vicende della vita di Nash colpirono profondamente Nasar e la indussero a passare i successivi tre anni a raccogliere informazioni e documenti per scrivere la prima biografia dell’ormai illustre matematico, uscita nel 1998 e diventata un libro di successo.Si tratta di una biografia del matematico, ma soprattutto dell’uomo Nash, la cui vita viene narrata in ordine rigorosamente cronologico: l’infanzia e i primi segni di genialità, i rapporti con la famiglia, la giovinezza e gli studi universitari, il lavoro di matematico, la relazione con Eleanor Stier e quella con Alicia Lardé, i due figli, gli incarichi presso la RAND e a Princeton. L’autrice, giornalista tedesco-americana con un passato da ricercatrice nel campo delle discipline economiche, se la cava egregiamente nel raccontare i principali contributi matematici del protagonista (tutti risalenti agli anni Cinquanta), che divide in tre parti: la teoria dei giochi non cooperativi, il teorema di immersione delle varietà riemanniane e i lavori sulle equazioni alle derivate parziali, tutte linee di ricerca estremamente produttive. Spiega anche gli altri studi che Nash condusse in vari campi della matematica (in particolare in teoria dei numeri) e della fisica, e che talvolta finirono in un vicolo cieco, senza per questo sminuire la genialità della mente di questo straordinario personaggio. Purtroppo quando ci si allontana dalla matematica verso altre discipline, Nasar incappa in qualche svarione, come quando afferma che la critica di Einstein alla meccanica quantistica non è mai stata confutata (p. 67), mentre è vero esattamente il contrario.Nasar sa rendere molto bene l’atmosfera estremamente competitiva che regna fra i giovani matematici, che hanno come obiettivo quello di pubblicare i lavori importanti tra i 25 e i 40 anni, quando le loro capacità intellettive sono al massimo (e in effetti la medaglia Fields viene assegnata entro i 40): si tratta di personalità molto complesse, decisamente eccentriche e spesso egocentriche, con una vena di goliardia mal trattenuta. La competizione è talmente forte che qualcuno abbandona la gara, mentre altri consumano letteralmente la propria esistenza per dimostrare una congettura o un teorema. Può sembrare che Nasar ecceda un po’ nel raccontare le bizzarrie di questi geni, tuttavia riesce a fornire uno spaccato vivido della società matematica americana, tra gli anni Quaranta e gli anni Settanta.Eccentrico e competitivo, Nash lo è al massimo grado, al punto che risulta eccessivo persino ai colleghi, ai familiari e agli amici. Dal libro emerge il ritratto di un uomo profondamente egocentrico con cui era difficile stabilire un rapporto che non si risolvesse modo conflittuale: si veda ad esempio la strana, altalenante relazione che Nash ebbe con il primo figlio (che non volle riconoscere), gli approcci omoerotici con alcuni colleghi, le difficoltà nel riconoscere l’importanza dei contributi altrui. L’unica persona con cui Nash riesce in qualche modo a stabilire un rapporto d’amore, anche se molto tormentato, è colei che diverrà (per due volte) sua moglie, Alicia Lardé, giovane studentessa appartenente a una famiglia aristocratica del piccolo stato centramericano di El Salvador: Alicia, di 7 anni più giovane di John, studia fisica al MIT e fin dal primo incontro con Nash, si innamora di lui e decide di dedicargli la propria esistenza. In breve i due si sposano e hanno un figlio.Sul finire degli anni Cinquanta le stranezze e gli squilibri di Nash aumentano di numero e di intensità, alienandogli molte amicizie e interferendo sempre di più con il suo lavoro e con la vita in famiglia. Per quanto sia difficile stabilire una cesura e una causa scatenante - le accuse di omosessualità, oppure il carattere segreto del lavoro svolto alla RAND, o magari il disappunto per essere stato preceduto da De Giorgi nella risoluzione del XIX problema di Hilbert e così via - a un certo punto il matematico sprofonda in uno stato di schizofrenia paranoide che distrugge quasi completamente la sua esistenza: rinuncia all’incarico a Princeton, entra ed esce dagli ospedali psichiatrici e viene sottoposto ad alcune terapie d’urto (come il famigerato shock insulinico) con il rischio concreto di danneggiare seriamente la sua mente matematica. Nonostante Alicia faccia di tutto per stargli accanto, a un certo punto persino lei getta la spugna e decide di divorziare da Nash, anche per scongiurare il rischio che il padre faccia male al bambino.Dopo dieci anni di calvario in istituti psichiatrici, agli inizi degli anni Settanta Alicia e John tornano a vivere insieme: lei lavora come impiegata per mantenere marito e figlio e lui, fisicamente ed emotivamente provato dalla malattia, trascorre una vita relativamente passiva in famiglia. Finalmente, intorno alla metà degli anni Ottanta, Nash sembra riemergere lentamente dalla schizofrenia, e riprendere i contatti con la comunità dei matematici, l’insegnamento e la ricerca scientifica. La sua diventa una vita sempre più tranquilla, sebbene segnata da altre sofferenze, legate ancora alla schizofrenia che ha colpito il figlio, John Charles. Un risveglio, quello di Nash, che culmina nell’assegnazione del Nobel, di cui si è detto e che occupa la parte finale del libro, in cui Nasar racconta le complicate manovre che portarono i membri del comitato svedese a premiare Nash fra numerose polemiche. In una conferenza dedicata a Nash che ho avuto la fortuna di seguire al Festival della Scienza di Genova alcuni giorni fa, Roberto Luchetti sosteneva che l’intera vita di Nash è intessuta di paradossi: la genialità accoppiata alla schizofrenia, il Nobel al posto della medaglia Fields che lui avrebbe preferito di gran lunga, e oltre tutto per un lavoro da lui considerato minore, due figli da due donne diverse ma due matrimoni con la stessa donna, Alicia, con la quale ha condiviso anche la morte, in un tragico incidente stradale, nel maggio 2015, mentre tornava da Oslo dove aveva ritirato il premio Abel per i suoi lavori sulle equazioni alle derivata parziali (anche questo, ahilui, condiviso). Forse il paradosso più sorprendente sta nella percezione che Nash aveva dei rapporti tra razionalità e irrazionalità. Citando dal saggio autobiografico che scrisse per il conferimento del Nobel:At the present time I seem to be thinking rationally again in the style that is characteristic of scientists. However this is not entirely a matter of joy as if someone returned from physical disability to good physical health. One aspect of this is that rationality of thought imposes a limit on a person's concept of his relation to the cosmos.Se questa biografia è capace di mettere bene in evidenza l’inclinare dei matematici verso la follia, lieve o intensa a seconda dei casi, nonché le fasi della schizofrenia di Nash, presenta però qualche difetto rilevante: il primo è il perdersi nei dettagli, nell’aneddotica e nei “si dice che”, “si pensa che”; il secondo è l’eccessivo peso dato alle interviste (basta scorrere le 60 pagine di note per rendersene conto) che mina un po’ la credibilità del lavoro per un personaggio così controverso, con il quale non era davvero facile mantenere rapporti sereni o imparziali; infine Nasar indulge un po’ troppo nel cliché del “genio folle”. L’edizione italiana che ho letto risale al 2008 e contiene davvero troppi refusi per essere la quinta ristampa dalla prima traduzione del 1999.Riguardo al film del 2001 che Ron Howard ha tratto dal libro (e che ha costretto l’editore a studiarle tutte per ripristinare il titolo originale: in questa edizione “A beautiful mind” appare come sottotitolo di “Il genio dei numeri”, che come titolo di per sé è alquanto improprio, e fa pensare più a Raymond Babbitt che non a un matematico), le storie narrate nelle due opere hanno qualche punto di contatto, ma sono sostanzialmente differenti: Howard ha cassato completamente i riferimenti alla relazione di Nash con Eleanor e all’omosessualità e ha raccontato i deliri di Nash in modo molto diverso da quelli che il matematico ha sperimentato nella realtà. Russell Crowe comunque non appare troppo fuori parte, dato che Nash da giovane era un muscoloso colosso, addirittura molto più alto dell’attore australiano. L’opera di Howard è nettamente agiografica, tuttavia ha l’indubbio pregio, anche più del libro, di aver fatto conoscere al grande pubblico la figura di Nash e, in parte, i suoi contributi matematici (più la teoria dei giochi che non i lavori sulle equazioni differenziali).Consigliato a chi sostiene il binomio genio-sregolatezza.Sconsigliato a chi odia la matematica.

    I remember being mesmerized by Russel Crowe's performance in the movie. I hadn't heard of Nash before and was hooked since. Nassar's book provides a wealth of detail about the maverick Nobel Laureate and a glimpse into his amazing life.

    I never would have thought a book on a real life person to be more interesting than the fictitious movie the book had inspired. It was amazing and so painfully cited that although it was an unofficial rendition of the life John Forbes Nash, Jr, it was in fact, more real than ever. Made you really wonder that it wasn't even for someone with a brilliant mind, it was a difficult life and a difficult time.It wasn't always that the truth can be as more puzzling as the reality. "A Beautiful Mind" is just like that. It detailed some of the events in Nash's life although seemingly at a distance, almost surgical, but the amount of the content the author had obtained made the movie somehow romanticize the man into a mythical math hero and made his life a film noir.It is a math book. Most of the time it does filled itself with literal theories without equations and numbers, but it was enough to provide concise explanation around Nash's academical life and his significance in the world of economics. For me, that was the most interesting part of the book while the second act, where he became to regress in his personal life was the one that made his story epic and surreal. Although some parts of the book was deeply personal and it felt invasive knowing about his marriage life and his life with his family, it didn't let go of the basic human story this book carry.What the book reveal to its audience was that this man who suffered manic depression, despite his gifts in logical and problem solving and impressive academic career, is still as human as us. With limitations and constraint, with problems and fault, strange and alien as he was with the rest of us, he wasn't flawless but his mind was much more than that and even in his suffering, everything made the man more than the rest of us.Oh, I caught a Doctor Who reference in the book. Find them.

    Well Well, if you want to see a nice film about a nice man conquering a nice mental illness then watch the film. If you want to find out about an awful guy getting an awful disease and ruining the lives of everybody that got close to him, then read the book. Sylvia Nasar paints a painful picture of loss. She describes the mystery world of schizophrenia as seen through the eyes of those people most hurt by it, the family and friends of John Nash. As a reader I couldn’t help but sympathise with Alicia and Eleanor and his children. He won the Nobel prize, but other than that John Nash was a complete failure as a human being. His remarkable recovery from schizophrenia and his ability to solve mathematical problems never quite make up for the awful neglect and selfishness of this man. Sylvia Nasar doesn’t hero worship though, she paints it as she sees it.The book is written fairly monotonously and is not that easy to read, though I did finish it in two sittings. Sometimes it seems that Sylvia struggles to make sense of her own notes and throws in disjointed quotes and snippets from other sources in a less than homogeneous way. In places this ruins the flow of the story. Ultimately the book is worth reading simply because of its honesty.

    In A beautiful mind it tells a story about Mr. Nash. He is like all of the other kids when he was younger. The book is a time line of his life. As the story proceeds, you will get pulled into his world. There are some of problems in his life that he will have to face or go through. He also, triumphs his old fears of his school and his friends. Towards the middle of the story; Like everyone in the story, Mr.Nash goes through some changes. He also,meets some new people that shares his interest in his studying; which is mathamatices. Mr.Nash works in a ivyleaugue school as a teacher. Through his teaching years, he becomes accutsomed to working all the time. Which leads to this "gift" he recevies later in the story. I believe this book is inspiring, because this man as went though colleges, a hospital, and a new family with a mental disorder. He did all of that and in return he gets something worth wild. This book touches my heart in a way no other book has done before. If you like to read about a man with a passion to learn, who learns how to face this fears and who gets thought a mental disorder then, you should read this story.

    The story is quite interesting. I didn't like the style of writing. There are too much information and details that makes it very unpleasant to read. I really struggled to finish the book. Sadly, For the first time, i would say: the movie was better than the book.
