Steven Cowley, director of the Princeton Plasma Physics Laboratory (PPPL), has spent a lifetime working to develop fusion energy as a viable source of electricity. But in his spare time, he enjoys investigating the role of magnetism in the universe.
“I’m a fusion nut and I spent most of my career talking about how to make fusion work,” Cowley told the audience at PPPL’s second Ronald E. Hatcher Science on Saturday lecture on “The Magnetic Universe” at PPPL on Jan. 19. “I’ve also done some work understanding magnetic field lines in the universe. It’s kind of a hobby.”
