The Origin of Species (英语) 平装 内容简介 'A grain in the balance will determine which individual shall live and which shall die...'. Darwin's theory of natural selection issued a profound challenge to orthodox thought and belief: no being or species has been specifically created; all are locked into a pitiless struggle for existence, with extinction looming for those not fitted for the task. Yet 'The Origin of the Species' (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and - by implication - within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, 'The Origin of the Species' remains one of the founding documents of the modern age. 作者简介 Charles Darwin was born in Shrewsbury, England, on February 12, 1809 into a prominent middle-class f

Grade 2-5 Cole and Degen have struck at the core once again to produce an exciting，attractive，and informative science book for young readers。Children who entered Ms。Frizzle’s classroom in The Magic School Bus at the Waterworks （Scholastic，1986），are in for another exhuberant，intriguing field trip。This time， it’s to the center of the earth。Surprises abound through each strata down to the very inner core where it is hot，hot，hot。The class collects rock samples before the bus is expelled from the earth’s core in a volcanic eruption。Illustrations are in watercolor cartoon format and attendant “balloons” contain pertinent information or students’humorous asides。There are also pages from students’reports on rocks。A tongue-in-cheek section at the end discusses the real and fantasy aspects of the book。Containing uncluttered text and illustrations， it is an anticipatory page-turner full of exciting adventure from school yard to volcano and back。Mary Lou Budd， Mil

Licklider was a brilliant scientist whose essential contributions to cognitive psychology and cybernetics included critical early developments in the field of man-machine interaction. However, his original work is often overshadowed by his accomplishments as a teacher, administrator and project leader and this ably written and well-researched biography isn't likely to propel him into the limelight. Waldrop (Man-Made Minds) devotes about 20% of the book to Licklider himself; the rest covers his teachers, colleagues and students at MIT and the Pentagon including computing pioneers Douglas Engelbart, Wes Clark and Larry Roberts and Licklider's indirect influence on the development of personal computers and the Internet (via "the world's first large-scale experiment in personal computing" at MIT). To his credit, Waldrop avoids common stereotypes of computer nerds or saints, delivering a vivid account of Licklider and his contemporaries. But he was not able to interview Licklider (who died in 1990), nor does he in
