G. H. Hardy was one of this century's finest mathematical thinkers, renowned among his contemporaries as a 'real mathematician ... the purest of the pure'. He was also, as C. P. Snow recounts in his Foreword, 'unorthodox, eccentric, radical, ready to talk about anything'. This 'apology', written in 1940 as his mathematical powers were declining, offers a brilliant and engaging account of mathematics as very much more than a science; when it was first published, Graham Greene hailed it alongside Henry James's notebooks as 'the best account of what it was like to be a creative artist'. C. P. Snow's Foreword gives sympathetic and witty insights into Hardy's life, with its rich store of anecdotes concerning his collaboration with the brilliant Indian mathematician Ramanujan, his aphorisms and idiosyncrasies, and his passion for cricket. This is a unique account of the fascination of mathematics and of one of its most compelling exponents in modern times.
A Mathematician's Apology is a profoundly sad book, the memoir of a man who has reached the end of his ambition, who can no longer effectively practice the art that has consumed him since he was a boy. But at the same time, it is a joyful celebration of the subject--and a stern lecture to those who would sully it by dilettantism or attempts to make it merely useful. "The mathematician's patterns," G.H. Hardy declares, "like the painter's or the poet's, must be beautiful; the ideas, like the colours or the words, must fit together in a harmonious way. Beauty is the first test: there is no permanent place in the world for ugly mathematics."
Hardy was, in his own words, "for a short time the fifth best pure mathematician in the world" and knew full well that "no mathematician should ever allow himself to forget that mathematics, more than any other art or science, is a young man's game." In a long biographical foreword to Apology, C.P. Snow (now best known for The Two Cultures) offers invaluable background and a context for his friend's occasionally brusque tone: "His life remained the life of a brilliant young man until he was old; so did his spirit: his games, his interests, kept the lightness of a young don's. And, like many men who keep a young man's interests into their sixties, his last years were the darker for it." Reading Snow's recollections of Hardy's Cambridge University years only makes Apology more poignant. Hardy was popular, a terrific conversationalist, and a notoriously good cricket player.
When summer came, it was taken for granted that we should meet at the cricket ground.... He used to walk round the cinderpath with a long, loping, clumping-footed stride (he was a slight spare man, physically active even in his late fifties, still playing real tennis), head down, hair, tie, sweaters, papers all flowing, a figure that caught everyone's eyes. "There goes a Greek poet, I'll be bound," once said some cheerful farmer as Hardy passed the score-board.
G.H. Hardy's elegant 1940 memoir has provided generations of mathematicians with pithy quotes and examples for their office walls, and plenty of inspiration to either be great or find something else to do. He is a worthy mentor, a man who understood deeply and profoundly the rewards and losses of true devotion. --Therese Littleton
1)數學是一流的,談論數學的學問是二流的,正如文學之於文學批評。2)純粹數學是真正的數學,應用數學是trivial的。3)對純粹數學的辯護是美學的,而非實用的。至少純粹數學是最無害的。4)其實最好的辯護是:如果再年輕一次,還是選擇做數學傢。5)老瞭就做不瞭數學瞭,數學是創造性的,而非沉思,屬於年輕人。
評分數學傢特有的貴族氣質
評分我學數學因為它美
評分悲觀地辯護著數學的“純粹美”。為瞭降低“花甲Hardy”消極情緒的負麵影響,務必與Wiener,“I Am a Mathematician”,和Halmos," I want to be a mathematician"一並依次閱讀,喜感將逐步上升——不傷身,不傷神。(Btw, Snow的序言很八卦很有趣)
評分"the noblest ambition is that of leaving behind something of permanent value", that something could be of many forms-ideas, views, other aspects of welfare that can make generations after generations better.

評分很有意思的小书。天才吐起槽真的酣畅淋漓,“年轻人应该自视甚高,但不应该愚蠢”,“好的工作都不是被‘谦逊的’人所做出来的”,书里辩白了数学家这种可爱的骄傲,来自于三点:1.智力上的好奇心,2.对职业的自豪感,3.抱负。“我做我所做之事乃是因为,它乃是我唯一完全能够...
