How did a single "genesis event" create billions of galaxies, black holes, stars and planets? How did atoms assemble -- here on earth, and perhaps on other worlds -- into living beings intricate enough to ponder their origins? What fundamental laws govern our universe?This book describes new discoveries and offers remarkable insights into these fundamental questions. There are deep connections between stars and atoms, between the cosmos and the microworld....

It seems like the perfect solution to a ballooning crime rate - filling the skies with flying robotic droids that can prevent murders before they take place. However, nobody told these "Watchbirds" that all life depends on a formula of carefully balanced killing. Robert Sheckley's renowned story examines one of the most important questions of our time - is it wise to sacrifice our liberty in the name of our security? Join host Professor Stephen Hawking...

How did the replication bomb we call "life" begin and where in the world, or rather, in the universe, is it heading? Writing with characteristic wit and an ability to clarify complex phenomena (the New York Times described his style as "the sort of science writing that makes the reader feel like a genius"), Richard Dawkins confronts this ancient mystery.

At once a spirited defense of Darwinian explanations of biology and an elegant primer on evolution for the general reader, What Evolution Is poses the questions at the heart of evolutionary theory and considers how our improved understanding of evolution has affected the viewpoints and values of modern man.

Ragnarok. Armageddon. Doomsday. Since the dawn of time, man has wondered how the world would end. In The Last Three Minutes, Paul Davies reveals the latest theories. It might end in a whimper, slowly scattering into the infinite void. Then again, it might be yanked back by its own gravity and end in a catastrophic "Big Crunch." There are other, more frightening possibilities. We may be seconds away from doom at this very moment. Written in clear language...

There is no more profound, enduring or fascinating question in all of science than that of how time, space, and matter began. Now John Barrow, who has been at the cutting edge of research in this area and has written extensively about it, guides us on a journey to the beginning of time, into a world of temperatures and densities so high that we cannot recreate them in a laboratory. With new insights, Barrow draws us into the latest speculative theories...

Energy flows all around you. It warms the air and powers our machines. In this book, readers in grades 4-9 will discover how power from the sun journeys to Earth's surface and back out to space. The sun's energy can be reflected, absorbed, used by plants and animals, given off, or trapped to warm the atmosphere. Learn how heat in the atmosphere is rising and what people can do about it. Earth's energy flow affects every living creature on the planet-including...

"A crack of lightning. The blue glow of a phone screen. A blinking firefly. The blazing sun. A camera's rapid flash. No matter the source, light travels in waves, and it does so at a speed faster than anything else in the universe. But what is light, and how do we study it? Read about light waves and light's properties and how people--and animals--manipulate light for their own purposes" -- Back cover.
