Can you find beauty -- even romance -- in mathematics? Mathematician Edward Frenkel, author of "Love and Math," joins Rationally Speaking to talk about how the subject seduced him as a young man, and how he believes it's generally mis-taught in schools. Other topics include: the search for a "grand unified theory" of mathematics, and the splash Edward caused when he produced -- and starred in -- "Rites of Love and Math," a steamy short film about equations.
