"What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? In elegant and accessible prose, theoretical physicist Carlo Rovelli leads us on a wondrous journey from Democritus to Einstein, from Michael Faraday to gravitational waves, and from classical physics to his own work in quantum gravity. As he shows us how the idea of reality has evolved over time, Rovelli offers deeper explanations of the theories...

What keeps objects from floating out of your hand? What if your feet drifted away from the ground? What stops everything from floating into space? Gravity, the invisible force that causes objects to attract each other. Here the author has taken a complex subject and made it brilliantly accessible to young readers in this unusual, innovative, and very beautiful book.

"It would be hard to imagine a better guide to this difficult subject." -- Scientific American In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the...

Why the force that keeps our feet on the ground holds the key to understanding the nature of time and the origin of the universe.
Gravity is the weakest force in the everyday world yet it is the strongest force in the universe. It was the first force to be recognized and described yet it is the least understood. It is a "force" that keeps your feet on the ground yet no such force actually exists.

"What is gravity and how does it work? Could Earth ever stop spinning, and what would happen if it did? How do astronauts prepare for a life with zero gravity? This book introduces readers to scintillating science topics using easy-to-understand diagrams and fun fact boxes. This book explores important concepts such as weight and mass, how gravity affects our solar system, and zero gravity. Engaging, concise text explains each concept thoroughly,...

Accurate enough to satisfy an expert, yet simple enough for baby, this clever board book explores the ups and downs of gravity. When baby drops food from a high chair, why does it fall? Beautiful, visually stimulating illustrations complement age-appropriate language to encourage baby's sense of wonder. Parents and caregivers may learn a thing or two, as well!

When published in 1973, Gravity's Rainbow expanded our sense of what the novel could be. Pynchon's extensive references to modern science, history, and culture challenged any reader, while his prose bent the rules for narrative art and his satirical practices taunted U.S. obscenity and pornography statutes. His writing thus enacts freedom even as the book's great theme is domination: humanity's diminished "chances for freedom" in a global military-industrial...
