Edgar Morin's remarkable investigation into the cultural and social significance of the star system traces its evolution from the earliest days of the cinema - when stars like Chap...(展开全部)

From the author of 'The Music of the Primes' and 'Finding Moonshine' comes a short, lively book on five mathematical problems that just refuse be solved -- and on how many everyday problems can be solved by maths. Every time we download a song from Itunes, take a flight across the Atlantic or talk on our mobile phones, we are relying on great mathematical inventions. Maths may...(展开全部)

马库斯·杜·索托伊（Marcus du Sautoy） 牛津大学数学教授、西蒙义讲座教授，英国工程暨物理研究委员会研究员，英国皇家协会研究员。马库斯是一位不按常理出牌的数学天才，他创造了“流行数学”的概念，将复杂的数字和数学概念用形象生动、通俗易懂的语言表达出来，被誉为“百家讲坛”式的学者。他是BBC科普节目嘉宾、TED演讲嘉宾，《泰晤士报》和《卫报》专栏作家，曾获伦敦数学会的贝维克奖、英国官佐勋章，并在2004年被英国《周日独立报》评为英国最杰出的科学家之一，被英国《绅士》杂志列为全英40岁以下最具影响力的百位人物之一。业余时间，他爱好足球运动，目前是英国作家足球队队员。

From hopscotch to Wayne Rooney with lots and lots of games to play, The Number Mysteries shows why mathematics really is at the heart of everything we do. 'Mind-bending, fascinating and useful too. Maths didn't used to be this much fun.' Alan Davies. We are all taught how fundamental mat...(展开全部)

阿瑟•克拉克（1917-2008） 英国科幻作家，与阿西莫夫、海因莱因并称为“世界科幻三巨头”。他一生创作了100多部作品，被翻译成40多种语言，多次获得星云奖、雨果奖等科幻至高奖项。其代表作有《童年的终结》《2001：太空漫游》《与拉玛相会》（双奖作品）及《天堂的喷泉》（双奖作品）等科幻史上的杰作。1986年，他获得美国科幻与奇幻作家协会终生成就奖——大师奖。 克拉克的绝大多数作品属于“硬科幻”，视野宏大，具有坚实的科学基础，同时饱含人文关怀，充满对人类文明终极意义的探索。克拉克早在1945年即提出利用同步卫星实现全球通信的设想。由于他的这一伟大贡献，国际天文学联合会将赤道上空的同步卫星轨道命名为“克拉克轨道”。

The man on the moon was dead. They called him Charlie. He had big eyes, abundant body hair and fairly long nostrils. His skeletal body was found clad in a bright red spacesuit, hidden in a rocky grave. They didn't know who he was, how he got there, or what had killed him. All they knew was that his corpse was 50,000 years old; and that meant that this man had somehow lived long...(展开全部)
