In Visions, physicist and author Michio Kaku examines the great scientific revolutions that have dramatically reshaped the twentieth century--the quantum mechanics, biogenetics, and artificial intelligence--and shows how they will change and alter science and the way we live. The next century will witness more far-reaching scientific revolutions, as we make the transition from unraveling the secrets of nature to becoming masters of nature. We will no longer be passive bystanders to the dance of the universe, but will become creative choreographers of matter, life, and intelligence.
