George Boole, for whom Boolean logic is named, developed the idea of expressing any idea as a mathematical or logical statement. Today, Boolean logic is foundational to computer programs and computer hardware, but it is also important in our everyday thinking. This guide includes an overview of logic gates and a review of differences between computer logic and human logic. The author's clever use of a famous movie line—"Lions and tigers and bears!"—truly helps make a potentially difficult topic easy to grasp for readers of all ages. Photographs, illustrations, and sidebars round out the educational experience.
