Howard Wolowitz is faculty at Caltech’s Department of Applied Physics who often hangs out at Leonard and Sheldon’s apartment. He designed a satellite that is currently orbiting a moon of Jupiter taking high-res photos and some of the components he has built are on the ISS. He doesn’t show signs of discontentment like Leonard, but rather is confident enough to try to woo Penny with his knowledge of languages, of which he knows six. Most of the languages were revealed in only the matter of one episode; in revealed order, they are English, French, Mandarin, Russian, Arabic, and Farsi. Hitting on Penny in different tongues has become a regular occurrence; one which angers Leonard greatly. Wolowitz also knows Klingon because as Sheldon stated, they all played Klingon Boggle together.
