Kunal Nayyar plays brainiac astrophysicist Raj Koothrappali on CBS’ hit show “The Big Bang Theory,” but it turns out the actor can hold his own in an impromptu science quiz.

HuffPost Live’s Caroline Modaressy-Tehrani put Nayyar to the test on Thursday and quizzed him on a few science facts. While Nayyar protested that he is “not smart in real life,” he passed the test with flying colors, proving he’s more clever than he thinks.

And acting and fielding spontaneous astronomy questions aren’t Nayyar’s only talents. The multifaceted star’s new book Yes, My Accent Is Real, which details Nayyar’s childhood and how he got into acting, is on shelves now.
