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
為什麼要學數學?數學的實際意義在哪裏?數學的永恒不朽和普遍意義(permanence, immortality,generality)區彆於其他科學學科。應用數學或可有所實用,但純數學的價值在哪裏?
評分沒想到在單位圖書館淘汰的書裏撿到寶,還是1967年劍橋精裝版。
評分這就是最好的那種文筆,如數學公式那樣簡潔優雅,不像小說傢那樣故作高深用很多生僻的詞彰顯自己的博學。生詞量很少看得很痛快,每次碰到生詞都感覺作者不得不精準錶達纔用的。讀後,感覺不僅僅是在探討數學的意義,更是在探討我們人生的意義。想起愛因斯坦的話,不是所有能被衡量的都有意義,也不是所有有意義的都可以被衡量。好書,值得反復讀。
評分我學數學因為它美
評分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。
英国大数学家哈代(Godfrey Harold Hardy)写过一本叫《一个数学家的辩白》(A Mathematician's Apology)的小书,至今亦广为流传,可惜我孤陋寡闻,上了大学才知道:那时刚上大学,喜欢吹水的小舟老师经常会在课堂上大谈数学的好处以及他的个人经历,这就正如哈代在书中所说的...
評分This is the reason we love Europe, the British Empire, and the nineteenth century. As Hardy himself said more than once in this essay, an "apology" is bound to be to some extent personal. Thus the reader's own life path and choices are sure to play a role i...
評分 評分这学期上的数学课名字很好听,叫The Art of Mathematical Thinking,是一门连接初等数学和高等数学的桥梁课程,主要用来学习怎么规范地写证明。开学不多久去和教授聊天,得知我准备主修数学和哲学之后给我看了一本小说,第一页的那句话摘自Hardy大叔的这本书,于是顺藤摸瓜从图...
評分▪ 正如哈代在《一个数学家的辩白》中所写的,在他的数学家名单中:"伽罗瓦(galois)21岁去世,阿贝尔(abel)27岁去世,拉 纽扬33岁去世,黎曼40岁……我不知道有哪一个重要的数学进展是由一个年过半百的人创始的。" ▪ 他像年轻人一样充满活力,他网球比以前打得更多,技艺...
