Editorial Reviews

Children's Literature
Although the text focuses on "Present Knowledge" and "Future Trends," this book begins with a whirlwind tour of the history of telecommunications, from the telegraph to the fax machine. Following this is a rather in-depth and technical discussion of the different types of telecommunications systems and signals, which is helpfully illustrated by a variety of charts and diagrams, but may be beyond many general readers. Of more interest may be the sections explaining how a cellular phone network works, as well as the structure of the Internet. One problematic feature of this book (as with any title that purports to discuss future directions in technology) is that some of the items (such as multifunction hand-held devices) that the text presents as cutting-edge and futuristic are already becoming commonplace. In addition to a variety of line drawings of various telecommunications networks, color photographs depicting telecommunications devices illustrate the text. Part of the "21st Century Science" series. 2004, Smart Apple Media, Ages 9 to 12.

Gr 5-9-Kerrod explains the processing of raw materials including metal, chemical raw materials, and fossil fuels, as well as how we use metals, synthetics, fibers, adhesives, ceramics, silicon, etc. The need to recycle and conserve our natural resources is addressed. Maddison includes topics from early methods of communication, such as the telegraph and radio, to the explanation of modern-day transmission of messages via various methods including telephone, wired and wireless networks, cellular phones, and satellites. Plentiful diagrams, photos, and drawings add color, appeal, and interest to each spread. These books should provide interested readers and researchers with ample facts and information as well as much food for thought.-Susan Shaver, Hemingford Public Schools, NE Copyright 2003 Reed Business Information.
