STEM subjects are where the future's at. Now you can be a science superstar with this colourful practice book. Are you a budding Einstein? Or do you need a little more help to avoid falling behind in science class? DK's How to be Good at Science, Technology, and Engineering course book for children aged 7-14 now has two accompanying workbooks: Workbook 1 covers ages 7-11 and Workbook 2 covers ages 11-14. These workbooks will help to cement everything you need to know about "STE" subjects through practice questions and practical exercises. Easy-to-follow instructions allow you to try out what you've studied, helping you understand what you've learned in school or giving extra revision practice before that important test. Workbook 2 is aimed at children aged 11-14 (Key Stage 3 in the UK; Grades 6, 7, and 8 in the US), and covers all the key areas of the school curriculum for this level, including genes and DNA, atoms and mole
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
本书从物理学而不是数学概念的角度介绍了目前动力系统中均匀双曲吸引子研究的进展小结构稳定的吸引子表现出强烈的*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。 本书可以作为研究生和高年级本科生教材，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。
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
