Leonard Hofstadter and Sheldon Cooper are both brilliant physicists working at Cal Tech in Pasadena, California. They are colleagues, best friends, and roommates, although in all capacities their relationship is always tested primarily by Sheldon's regimented, deeply eccentric, and non-conventional ways. They are also friends with their Cal Tech colleagues mechanical engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The foursome spend their time working on their individual work projects, playing video games, watching science-fiction movies, or reading comic books. As they are self-professed nerds, all have little or no luck with women. When Penny, a pretty woman and an aspiring actress from Omaha, moves into the apartment across the hall from Leonard and Sheldon's, Leonard has another aspiration in life, namely to get Penny to be his girlfriend.
Smart Is The New Sexy.

There are 16 mailboxes but the building has only ten apartments - two on each of the five floors. Since all apartments are numbered by the floor plus a letter (the guys live in 4A, Penny in 4B) it is not possible that there is a never seen third apartment on each floor. First off, there are no apartments shown on the first floor. Secondly, it is possible that there are four apartments on each floor (two being unseen), and furthermore there is at least one more floor above the one Sheldon, Leonard, Penny, and later Amy live on (since the hallway/stairs/elevator scene is recycled for each floor).
