Book excerpt: Integrating technological innovations into our daily lives has helped to modernize and improve the way we learn, the way we do business, the way we communicate with one another, and ultimately the way we live. But in these modern times, which some refer to as the “Electronic Gadgets and App Age,” it has become difficult to know everything about the old and new electronic devices that continue to make the wheels of industry turn in society. New innovations appear and then just as quickly become antiquated and obsolete; technological advances from the past blend with the present and then, like ripples in a lake, fade in this fast-paced world. How can anyone hope to keep up with those changes? The breadth of knowledge required is daunting, but technology impacts the choices we make, for better or worse. Revolutionary Technologies: Educational Perspectives of Technology History covers what has been invented, who invented what, and how technology has made our lives more efficient, enjoyable, and meaningful.
