The stunning pictures bring the theory of evolution to life for young readers, and anyone who wants to learn about evolution.Pulling together Darwin's observations from his travels around the world and his ground-breaking explanation of how species form, develop, and change over hundreds of thousands of years, On The Origin of Species is as relevant and important now as it ever was.A very important project, most beautifully realised.

    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.

Open the book, and the reader is swept into the magic of an underwater world, face-to-face with a floating Yellow-Banded Sweetlips; with a glow-in-the-dark Deep-Sea Anglerfish; with a Sea Horse swaying in balletic motion; with a Sand Tiger Shark gliding along the ocean floor, its gaze haunting, its hook-toothed mouth gulping open and closed. The text by Carol Kaufmann enchants with its descriptions of coral reefs; a journey on Alvin, the 17-ton submersible; and a meditation on our oceans. Then, for each creature, she writes a lively and informative essay, along with vital statistics—size, habitat, range, diet, and more. The Photicular process uses an innovative lenticular technology, sliding lenses, and original four-color video imagery. The result is like a movie in your hands—the dance of life in a book.
