In Search of the Shape of the Universe

March 27, 2007

How are things connected? What is the true shape of those things? Mathematicians have attempted to prove or disprove a tantalizing puzzle related to these questions since it was first posed by Henri Poincar?? in 1904. Our guest this hour, Professor Donal O’Shea of Mount Holyoke College in Massachusetts, believes the proposition may have been proved. He writes about what has been called one of the greatest unsolved problems of the new millennium in his new book “The Poincar?? Conjecture: In Search of the Shape of the Universe”(Walker and Company, 2007).
