Skeptic: Promoting Science and Critical Thinking

The concept of additional spatial dimensions is as far from intuitive as any idea can be. In this lecture based on her new book, Dr. Randall employs creative analogies to explain how our universe may have many unseen dimensions. Randall works hard to make her astoundingly complex material understandable, providing a great deal of background for recent advances in string and supersymmetry theory. As coauthor of the two most important scientific papers on this topic, she’s ideally suited to explain these ideas. Although physicists do not yet know if there are extra dimensions a fraction of a millimeter in size, dimensions of infinite size, or only the dimensions we see, Randall shows how these theories will be tested in coming years.

Dr. Randall is a professor of physics at Harvard University and one of the leading theoretical physicists in the world today who works on string theory, particle physics, and cosmology.
