The animal species introduced in this book are truly mind-boggling. How can an animal fly if it doesn't have wings? Readers find out. Books of the Real Life Readers Program use real life scenario narratives to help readers further develop content-area reading, writing, and comprehension skills.

Wings carry tiny insects, fluttering butterflies, and backyard birds, and they even once propelled some dinosaurs up and through the skies. Find out how, when, and why birds and beasts have taken to the air, and discover how wings work in this informative and brilliantly illustrated book about flight.

Erwin Schrödinger is one of the greatest figures of theoretical physics, but there is another side to the man: not only did his work revolutionize physics, it also radiacally changed the foundations of our modern worldview, modern biology, philosophy of science, philosophy of the mind, and epistemology. This book explores the lesser-known aspects of Schrödinger's thought, revealing the physicist as a philosopher and polymath whose highly original ideas anticipated the current merging of the natural and the social sciences and the humanities. Thirteen renowned scientists and philosophers have contributed to the volume. Part I reveals the philosophical importance of Schrödinger's work as a physicist. Part II examines his theory of life and of the self-organization of matter. Part III shows how Schrödinger's ideas have influenced contemporary philosophy of nature and our modern view of the world, drawing a fascinating picture of the ongoing synthesis of nature and culture: one of the most interesting developments of modern thought. The volume also contains the most comprehensive bibliography of Schrödinger's scientific work, making it at the same time a book of acute contemporary relevance and a major work of reference.

Did you know that many species are able to glide through the air using loose flaps of skin or other adaptations? This is called passive flight because the animal does not need to use its own energy to stay in the air. Discover these and other intriguing facts in Flight.
