In this lively and stimulating account, noted mathematician and educator W. W. Sawyer (Professor Emeritus, University of Toronto) defines mathematics as "the classification and study of all possible patterns." It is a broad definition, but one that seems appropriate to the great scope and depth of the topic. Indeed, mathematics seems to have few boundaries, either in applicatio...(展开全部)

It is the year 12,020 G.E. and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, forty billion people have created a civilization of unimaginable technological and cultural complexity. Yet Cleon knows there are those who would see him fall - those whom he would destroy if only he could read the future. ...(展开全部)

回顧科學的進展，你會驚訝地發現，刻卜勒預測行星繞日軌道的靈感，來自千年前古希臘人研究的橢圓；愛因斯坦的相對論所用到的數學理論，幾十年前就已經有數學家提出來了；後來應用在晶體學、物理、化學等領域的群論，最初單純用來研究解代數方程式的問題。 喜歡抽象思考的數學家，通常只是受一個理論的「美」所吸引而去研究，儘管理論本身並沒有實用價值，但多年之後，這些理論能夠在其他領域有所應用，發光發熱。數學家的純粹思路，往往是無比力量的源頭。 你好奇「數學家是怎麼思考的」嗎？這本書可以為你解答。多倫多大學榮譽教授梭爾，用深入淺出的文字，娓娓道出數學家的思考智慧，而你只要具備高中數學程度，就能從本書中領會非歐幾何、矩陣、變換、群論、射影幾何等課題的面貌。

His eyes were open now, watching the path of the tiny flame. If you continue your path, little spark, you will cause great harm.I must burn! I must live!There are places where your glow and heat are welcome. Find them, do not destroy the dwellings or take the lives of my people!For a second, he seemed to wink out of existence but then blazed back with renewed vigor.Thrall knew ...(展开全部)

The SARS epidemic of 2003 was one of the most serious public health crises of our times. The event, which lasted only a few months, is best seen as a warning shot, a wake-up call for public health professionals, security officials, economic planners, and policy makers everywhere. SARS (Severe Acute Respiratory Syndrome) is one of the “new” epidemics. SARS in China addresses the...(展开全部)
