Kummer covers the history of currency around the world, how money is made, and its prospective use in the future. Information about early barter systems and the role that currency plays in modern society are also included. Masters provides background on the Wright brothers and their work, early flying machines, and the future of aviation. Scientific principles of flight are outlined. Orr discusses the invention of the telescope, early models, and the future of exploring the universe. A chapter is dedicated to Galileo and his research. All three books have appropriate color and black-and-white photographs, reproductions, and/or diagrams on virtually every spread.
