FROM ONE OF TIME MAGAZINE’S 100 MOST INFLUENTIAL PEOPLE IN THE WORLD, Harvard University physicist and cosmologist Dr. Lisa Randall presents a rousing defense of the role of science in our lives. The latest developments in physics have the potential to radically revise our understanding of the world: its makeup, its evolution, and the fundamental forces that drive its operation. Knocking on Heaven’s Door is an exhilarating and accessible overview of these developments and an impassioned argument for the significance of science. She examines the role of risk, creativity, uncertainty, beauty, and truth in scientific thinking, along with the nature and goals of the largest machine ever built: the Large Hadron Collider, the enormous particle accelerator below the border of France and Switzerland—as well as recent ideas underlying cosmology and current dark matter experiments, and what they tell us about who we are and where we came from.
