On a quiet afternoon, you settle in for some long-awaited reading. All is restful, still, serene. And yet, almost imperceptibly, your surroundings seethe with activity. Light beams produced 93 million miles away stream through your window and slam onto the page at 186,000 miles per second. The air in your home writhes with constant changes in temperature. A bird sings, and atoms in the air collide with your eardrums at hundreds of miles per hour. All the while, Earth’s rotation is whipping you around the sun at 18 miles per second. Frenetic though they seem, these activities happen according to natural laws that make our world predictable. And now, in this newly-updated bestseller from National Geographic, the hows and whys of science become engagingly clear.
