Here is a provocative collection of essays by Philip Morrison, widely known for his work on the Manhattan project, and later for his involvement in quantum and nuclear physics and high energy astrophysics. Morrison offers a stimulating look at diverse subjects ranging from cosmology (particularly interstellar communication) to nuclear disarmament to creative ways of teaching science. He also offers his own perspective on his inspiring friendships with Niels Bohr, Richard Feynman, Bernard Peters, and other physics giants.
