In the fall of 1959, for a time capsule, students draw pictures of life as they imagine it will be in 50 years. Lucinda, an odd child who hears voices, swiftly writes a long string of numbers. In 2009, the capsule is opened; student Caleb Koestler gets Lucinda s drawing and his father John, an astrophysicist and grieving widower, takes a look. He discovers dates of disasters over the past 50 years with the number who died. Three dates remain, all coming soon. He investigates, learns of Lucinda, and looks for her family. He fears for his son, who s started to hear voices and who is visited by a silent stranger who shows him a vision of fire and destruction. What s going on?

A teacher opens a time capsule that has been dug up at his sons elementary school; in it are some chilling predictions - some that have already occurred and others that are about to - that lead him to believe his family plays a role in the events that are about to unfold.

We ask question after question of an indifferent universe that would just as soon remain mute; and slowly, patiently, one sentence at a time, we write our own version of the book of nature. It is called science, from the Latin word for knowledge, and it is a book everybody should read. With simplicity and elegance, Knowing interprets the book of nature for curious readers of all sorts-but especially for those hoping to appreciate the beauty of physics without getting lost in the mathematics. Indeed, there is a world of scientific understanding in the pages of this gracefully written and inviting book, where hundreds of little diagrams substitute for the equations that physicists otherwise need to tell their tale. Readers will discover the way things work: how big things (like Earth or Moon) come from small things (like quarks and electrons), how tiny particles push and pull, and how the world hangs in the balance.
