Last month theoretical physicist Sean Carroll spoke at Book Works, Del Mar, Calif., about his new book, From Eternity to Here: The Quest for the Ultimate Theory of Time (Dutton). Some 100 people attended, and Carroll commented that he's always happily surprised to see so many people come out for a night of theoretical physics. C-Span was on hand and will air Carroll's talk next Monday, March 8, at 6 a.m. ET.
