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 about the nature of time and the "inflationary universe," explains "wormholes," showing how they bear upon the fact of our own existence, and...

Come on a journey into the heart of matter--and enjoy the process --as a brilliant scientist and entertaining tour guide takes you on a fascinating voyage through the Periodic Kingdom, the world of the elements. The periodic table, your map for this trip, is the most important concept in chemistry. It hangs in classrooms and labs throughout the world, providing support for students, suggesting new avenues of research for professionals, succinctly organizing the whole of chemistry. The one hundred or so elements listed in the table make up everything in the universe, from microscopic organisms...

Laboratory Earth taps the relevant knowledge from physical, biological, and social sciences needed to study the planet holistically. This so-called Earth Systems Science fosters a new way to understand the Earth and our roles as inhabitants, with the purpose of building solutions to the bewildering global environment and overdevelopment.Educational, business, health, and governmental organizations often dissect the world into narrow but highly specialized disciplines--economics, ecology, cardiology, meteorology, glaciology, or political science, to name a few. But real world problems,...

Combining ideas from philosophy, artificial intelligence, and neurobiology, Daniel Dennett leads the reader on a fascinating journey of inquiry, exploring such intriguing possibilities as: Can any of us really know what is going on in someone else's mind? What distinguishes the human mind from the minds of animals, especially those capable of complex behavior? If such animals, for instance, were magically given the power of language, would their communities evolve an intelligence as subtly discriminating as ours? Will robots, once they have been endowed with sensory systems like those that...

Evolution is the most important idea in biology, with implications that go far beyond science. But despite more than a century's progress in understanding, there is still widespread confusion about what evolution is, how it works and why it is the only plausible mechanism that can account for the remarkable diversity of life on Earth. In this book, aimed at a general audience, author Ernst Mayr tells us what we know - and what we do not know - about evolution. In showing how evolution has gone from theory to fact, he explores various controversial fads and fallacies such as punctuated...
