How in the world can sounds be sent from here to there, even without a wire? Written by a physicist for his adult grandchildren, this little book explains the concepts, and it's too good not to share. Three early discoveries in electricity & magnetism led directly to the telegraph, telephone, and radio, respectively. Their mysteries are described here without math, and only the bare essentials are covered - the rest is just details. It will be eye-opening if your interests include technology's history, STEM education, amateur radio, or how things work in general. It may even be helpful to students who plow through complicated mathematics without a visceral feeling for these concepts and their history. The book is beautifully illustrated with color photographs and diagrams.
