In this revolutionary book, a renowned computer scientist explains the importance of teaching children the basics of computing and how it can prepare them to succeed in the ever-evolving tech world. Computers have completely changed the way we teach children. We have Mindstorms to thank for that. In this book, pioneering computer scientist Seymour Papert uses the invention of LOGO, the first child-friendly programming language, to make the case for the value of teaching children with computers. Papert argues that children are more than capable of mastering computers, and that teaching computational processes like de-bugging in the classroom can change the way we learn everything else. He also shows that schools saturated with technology can actually improve socialization and interaction among students and between students and teachers. Technology changes every day, but the basic ways that computers can help us learn remain. For thousands of teachers and parents who have sought creative ways to help children learn with computers, Mindstorms is their bible.

A thorough introduction to the computation of celestial mechanics, covering everything from astronomical and computational theory to the construction of rapid and accurate applications programs. The book supplies the necessary knowledge and software solutions for determining and predicting positions of the Sun, Moon, planets, minor planets and comets, solar eclipses, stellar occultations by the Moon, phases of the Moon and much more. This completely revised edition takes advantage of C++, and individual applications may be efficiently realized through the use of a powerful module library. The accompanying CD-ROM contains the complete, fully documented and commented source codes as well as executable programs for Windows 98/2000/XP and LINUX.

The revolution in accessible computer technology was fueled by disability activism, the interactive nature of personal computers, and changing public policy. In 1974, not long after developing the first universal optical character recognition technology, Raymond Kurzweil struck up a conversation with a blind man on a flight. Kurzweil explained that he was searching for a use for his new software. The blind man expressed interest: One of the frustrating obstacles that blind people grappled with, he said, was that no computer program could translate text into speech. Inspired by this chance meeting, Kurzweil decided that he must put his new innovation to work to “overcome this principal handicap of blindness.” By 1976, he had built a working prototype, which he dubbed the Kurzweil Reading Machine. This type of innovation demonstrated the possibilities of computers to dramatically improve the lives of people living with disabilities. In Making Computers Accessible, Elizabeth R. Petrick tells the compelling story of how computer engineers and corporations gradually became aware of the need to make computers accessible for all people. Motivated by user feedback and prompted by legislation such as the Americans with Disabilities Act, which offered the promise of equal rights via technological accommodation, companies developed sophisticated computerized devices and software to bridge the accessibility gap. People with disabilities, Petrick argues, are paradigmatic computer users, demonstrating the personal computer’s potential to augment human abilities and provide for new forms of social, professional, and political participation. Bridging the history of technology, science and technology studies, and disability studies, this book traces the psychological, cultural, and economic evolution of a consumer culture aimed at individuals with disabilities, who increasingly rely on personal computers to make their lives richer and more interconnected.

Personal computers have made life convenient in many ways, but what about their impacts on the environment due to production, use and disposal? Manufacturing computers requires prodigious quantities of fossil fuels, toxic chemicals and water. Rapid improvements in performance mean we often buy a new machine every 1-3 years, which adds up to mountains of waste computers. How should societies respond to manage these environmental impacts? This volume addresses the environmental impacts and management of computers through a set of analyses on issues ranging from environmental assessment, technologies for recycling, consumer behaviour, strategies of computer manufacturing firms, and government policies. One conclusion is that extending the lifespan of computers (e.g. through reselling) is an environmentally and economically effective strategy that deserves more attention from governments, firms and the general public.
