Watching poker players bluff inspired John von Neumann to construct game theory, a mathematical study of conflict and deception.

The second half of the 20th century witnessed a scientific gold rush as physicists raced to chart the inner workings of the atom. The stakes were high, the questions were big, and there were Nobel Prizes and everlasting glory to be won. Many mysteries of the atom came unraveled, but one remained intractable-what Frank Close calls the "Infinity Puzzle."

Dark Matter and the Dinosaurs is Lisa Randall’s most popular science book and proposes a new theory about the extinction of dinosaurs. The famous physicist and Nobel Prize winner Kip Thorne commented on the book: “Although it is a popular science book, it reads like a detective story. The writing uses scientific facts, coupled with rigorous logical reasoning, and reaches a shocking conclusion.”
