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

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

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
