Technology pervades our daily lives and modern society, and not just when it comes to computers and smart phones. Before there was the computer, there was the abacus. Before the smart phone, there was the telegraph and ball point pen. Electricity, penicillin, and the compass have all led to revolutionary changes in how we live. The Handy Technology Answer Book explains how technology has revolutionized the way people live, work, and play. It covers a broad range of fields, including medicine, mining, buildings, transportation, the military, and agriculture, and how they have been changed by technology. From the relationship between science and technology to nanotechnology, robots, and predictions for future technology, The Handy Technology Answer Book presents the latest and historical in an engaging and informative format. It brings well-researched answers to more than 1,100 common questions on technology, such as What are the major time periods of technology? Who is considered to be the first engineer? Which individual was granted the most U.S. patents? What is a Uniform Resource Locator, or URL? What products are made from recycled plastic? Can human beings be cloned? What is the future of wearable technology in health care?

Did you know that electric current can be controlled? Have you ever wondered how that might be done? Transistors can act as amplifiers, taking in a small current and sending out a larger one, or as switches, turning electric current on and off. But how do these different transistors work? How are they used in our electronic devices? Discover the history of how transistors were developed, explore how different types of transistors can play different roles in electronics, and learn where transistors may be taking technology in the future!
