“When I go to parties, people often look stunned at how smart I am. But nobody wants to talk about astrophysics at a dinner party. Hey, when I want to talk like that, I head to the lab! Instead, I talk about “human” things they enjoy and understand: midrange wines, movie trivia, and mundane subjects like family and emotional fulfillment. I like to end my conversations with a quote, usually something in French, like “c’est la vie,” which means “down the hatch!” But don’t overdo it: Nobody likes a show-off.”
