Ingenium

"Ingenium is medieval English vernacular for "an ingenious contrivance." In this book, physicist Mark Denny considers five such contrivances and demonstrates how they literally changed the world. Interweaving narrative with diagrams, equations, and drawings, Denny shares the history of each device, explains the physics behind it, and describes how it was used, how it evolved, and why it is significant in today's world."--Jacket.
