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 ... Jason Chin has taken a complex subject and made it brilliantly accessible to young readers in this unusual, innovative, and very beautiful book.

"An award-winning science writer traces our millennia-long effort to understand the phenomenon of gravity--the greatest mystery in physics, and a force that has shaped our universe and our minds in ways we have never fully understood until now"--

Traces how the human image of the world has changed throughout history, demonstrating the evolution of the idea of reality while touching on subjects ranging from the Higgs boson to quantum gravity.

Discusses the concept of gravity from its earliest recognition in 1666 to the discovery of gravitational waves in 2015, and explains why gravity holds the key to understanding the nature of time and the origin of the universe.

Explains the concept of gravity and suggests activities for understanding how gravity works on everyday objects.

A simple introduction to gravity, describing what it is and giving some effects of this force.

Defines gravity and discusses how our knowledge of the natural force has broadened and evolved.

Presents information on the scientific principle of gravity, how it was discovered, and how knowledge of its effects is applied by astronomers. Includes directions for a simple experiment.

"Physicists will tell you that four forces control the universe. Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force of gravity but couldn't explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity, showing how matter warps space and time. Not only did this explain how gravity...
