Children's Literature - Hazel BuysThe complex world of digital technology is stripped to its essentials and presented as a graduated series of developments, each a logical progression of the preceding technology. Thus, the science behind the digital world is appropriately simplified and clarified. The binary numbering system was first described by Gottfried Wilhelm Leibniz (16461716) and is the basis for all digital technology. The concept is explained in a sequence of examples that clarify its function. Black type stands out against different colors on pages that are intersected by squares of supplemental information. Bold, contrasting headings introduce each of the eighteen chapters. Charts, photographs, and diagrams fill in with history, "History Focus" or facts, "Fact Focus." These graphics also supplement the text. The progression of the technologies described in each succeeding chapter reflects the evolution of the science in the culture from the development of CDs, DVDs, digital music players, and computer-aided design, through the invention of the World Wide Web, digital broadcasting, and wireless networks. Concluding chapters discuss the advantages and risks of digital technologies and suggest future uses. Information provided at the end of the book includes a time line, glossary, a list of resources for further information, and an index. This book would be an excellent resource in a middle school or high school science classroom or library. Part of the "Science in Focus" series.
