Broca's Brain: Reflections on the Romance of Science is a 1979 book by the astrophysicist Carl Sagan. Its chapters were originally articles published between 1974 and 1979 in various magazines, including The Atlantic Monthly, The New Republic, Physics Today, Playboy, and Scientific American. In the introduction, Sagan wrote: As long as there have been human beings, we have posed the deep and fundamental questions. ... If we do not destroy ourselves, most of us will be around for the answers. ... By far the most exciting, satisfying and exhilarating time to be alive is the time in which we pass from ignorance to knowledge on these fundamental issues. Source: Wikipedia (en)
