Eighty-six years ago, physicist Paul Dirac theorized the existence of magnetic monopoles; that is, magnet poles that exist independent of each other. Not north and south together. North. And south. Separately.
Nearly a century later, Felix Flicker, a Berkeley theoretical physicist and post-doctoral researcher in the lab of Norman Yao, is working to help prove Dirac’s theory. “There was this sort of philosophical point I was thinking of,” Flicker says. “You can’t have the left end of a stick without the right end, can you?”
