Richard Feynman is one of the most brilliant and fascinating physicists of the twentieth century. He picked locks for fun at the Manhattan Project, reinvented quantum physics and investigated the space shuttle Challenger tragedy. Author Jim Ottaviani and artist Leland Myrick collaborated to create the graphic novel "Feynman" about his life. In this excerpt, Feynman shares the groundwork of quantum electrodynamics with students in New Zealand. Excerpted with permission from the publisher, First Second Books.
