"Harley-Davidson" is a visual celebration of the most famous motorcycle in the w.orld. The history of this legendary brand is told through a series of stunning, full-color photographs of its most famous （and infamous） marques. Each featured machine is accompanied by fascinating text that describes its design, historicalsignificance,and individual background,including the personal anecdotes of their owners.From the earliest "Singles" to the sport-bikes of the 21st century, the story of Harley-Davidson thunders to life in this exciting volume.

The publication of Darwin’s The Origin of Species in 1859marked a dramatic turning point in scientific thought. The volumehad taken Darwin more than twenty years to publish, in part becausehe envisioned the storm of controversy it was certain to unleash.Indeed, selling out its first edition on its first day, The Originof Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance histheory of natural selection and his assertion that species were notcreated all at once by a divine hand but started with a few simpleforms that mutated and adapted over time. Whether commenting on hisown poor health, discussing his experiments to test instinct inbees, or relating a conversation about a South American burrowingrodent, Darwin’s monumental achievement is surprisingly personaland delightfully readable. Its profound ideas remain controversialeven today, making it the most influential book in the naturalsciences ever written—an important work n

The Complete Encyclopedia of Formula One chronicles the history of the world championship,from Giuseppe Farina's victory for Alfa Romeo at Silverstone on 13 May 195o to the present day. All the top drivers are profiled, and there is a wealth of information on the major marques and championship venues,while the comprehensive statistics section will settle many an argument. It is a story of ingenuity and endeavour, rivalry and camaraderie, triumph and tragedy,in pursuit of the greatest prize in motor sport.

In this remarkable collection, 24 reproductions of historic photographs and paintings recapture the character, magnitude, spirit and tragedy of the great ship. All cards are identified by brief, de*ive notes, perforated and easily detachable for sending or saving.

本书从物理学而不是数学概念的角度介绍了动力系统中均匀双曲吸引子目前的进展。结构稳定的吸引子表现出强烈的随机性，但是对于动力系统中函数和参数的变化不敏感。基于双曲混沌的特征，本书将展示如何找到物理系统中的双曲混沌吸引子，以及怎样设计具有双曲混沌的物理系统。本书可以作为本科高年级和研究生教材，也可以供大学教授以及物理学、机械学和工程学相关研究人员参考。Kuznetsov 博士是非线性和混沌动力学方面的著名科学家。他是俄罗斯萨拉托夫国立大学非线性过程系的教授，已经出版了三本混沌动力学及其应用方面的专著。关键词：动力系统、混沌、奇怪吸引子, Plykin 吸引子, Smale – Williams 吸引子, 双曲吸引子

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
