Book Description
Kids will learn how things they encounter every day operate by building their own models with this hands-on activity book. Projects include building a working model of the human hand's muscles, bones, and tendons using drinking straws, tape, and string; using a pair of two-liter bottles and a length of rubber tubing to learn how a toilet flushes; and discovering how musical instruments make sounds by fashioning a harmonica, saxophone, drum, flute, or oboe. All devices are designed to use recycled or nearly free materials and common tools. Kids are encouraged to modify and improve the designs, or create an entirely new device using the concepts explored. Each project includes materials and tools lists, step-by-step instructions with photographs, a summary of the science concept demonstrated, and follow-up questions to gauge student understanding for use in the classroom.

Book Description
"Full of ideas and well-explained principles that will bring new understanding of everyday things to both scientists and non-scientists alike."—R. McNeill Alexander, Nature Nature and humans build their devices with the same earthly materials and use them in the same air and water, pulled by the same gravity. Why, then, do their designs diverge so sharply? Humans, for instance, love right angles, while nature's angles are rarely right and usually rounded. Our technology goes around on wheels—and on rotating pulleys, gears, shafts, and cams—yet in nature only the tiny propellers of bacteria spin as true wheels. Our hinges turn because hard parts slide around each other, whereas nature's hinges (a rabbit's ear, for example) more often swing by bending flexible materials. In this marvelously surprising, witty book, Steven Vogel compares these two mechanical worlds, introduces the reader to his field of biomechanics, and explains how the nexus of physical law, size, and convenience of construction determine the designs of both people and nature. "This elegant comparison of human and biological technology will forever change the way you look at each."—Michael LaBarbera, American Scientist

Book Description
Whether playing at defending their own castle or simply chucking pumpkins over a fence, wannabe marauders and tinkerers will become fast acquainted with Ludgar, the War Wolf, Ill Neighbor, Cabulus, and the Wild Donkey—ancient artillery devices known commonly as catapults. Building these simple yet sophisticated machines introduces fundamentals of math and physics using levers, force, torsion, tension, and traction. Instructions and diagrams illustrate how to build seven authentic working model catapults, including an early Greek ballista, a Roman onager, and the apex of catapult technology, the English trebuchet. Additional projects include learning how to lash and make rope and how to construct and use a hand sling and a staff sling. The colorful history of siege warfare is explored through the stories of Alexander the Great and his battle of Tyre; Saladin, Richard the Lionheart, and the Third Crusade; pirate-turned-soldier John Crabbe and his ship-mounted catapults; and Edward I of England and his battle against the Scots at Stirling Castle.

Book Description
A Major Contribution to the History of Technology and Ancient Warfare The most recognized military device of ancient times and the source of continued fascination and popular appeal, the catapult represented a major shift in the conduct of warfare. In "The Catapult: A History" historian Tracey Rihll uses ancient sources and the latest archaeological findings to tell the story of this first machine of war. Dispelling any notion that the catapult was precision engineered in the modern sense, the author explains how a robust formulaic design allowed a variety of machines and missiles to be built and used for particular battlefield conditions or military tasks. Complete with original illustrations, maps, and two appendices detailing both the formulas for catapult construction and known catapult remains, "The Catapult" is essential reading for those interested in the history of warfare and technology.

Book Description
Based on an incredible true episode of World War II history, Paul Malmont’s new novel is a rollicking blend of fact and fiction about the men and women who were recruited to defeat the Nazis and ended up creating the future. In 1943, when the United States learns that Germany is on the verge of a deadly innovation that could tip the balance of the war, the government turns to an unlikely source for help: the nation’s top science fiction writers. Installed at a covert military lab within the Philadelphia Naval Yard are the most brilliant of these young visionaries. The unruly band is led by Robert Heinlein, the dashing and complicated master of the genre. His “Kamikaze Group,” which includes the ambitious genius Isaac Asimov, is tasked with transforming the wonders of science fiction into science fact and unlocking the secrets to invisibility, death rays, force fields, weather control, and other astounding phenomena—and finding it harder than they ever imagined. When a German spy washes ashore near the abandoned Long Island ruins of a mysterious energy facility, the military begins to fear that the Nazis are a step ahead of Heinlein’s group. Now the oddball team, joined by old friends from the Pulp Era including L. Ron Hubbard (court-martialed for attacking Mexico), must race to catch up. The answers they seek may be locked in the legendary War of Currents, which was fought decades earlier between Nikola Tesla and Thomas Edison. As the threat of an imminent Nazi invasion of America grows more and more possible, events are set in motion that just may revolutionize the future—or destroy it—while forcing the writers to challenge the limits of talent, imagination, love, destiny, and even reality itself. Blazing at breathtaking speed from forgotten tunnels deep beneath Manhattan to top-secret battles in the North Pacific, and careening from truth to pulp and back again, The Astounding, the Amazing, and the Unknown is a sweeping, romantic epic—a page-turning rocket ship ride through the history of the future.
