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.

Did You Know?
In the early episodes of season one, Sheldon (Jim Parsons
) has two character traits that were not established right away. First, he understood the nature of romantic and sexual relationships. In the first few episodes, he chides Leonard (Johnny Galecki
) for his hopes of getting into a relationship with Penny (Kaley Cuoco
), often telling Leonard that he has no chance of having sex with her. Also, Sheldon understood the nature of sarcasm, as he occasionally used it himself in the early episodes. Later, his character evolved into a purely intellectual person and an emotional "man-child", who does not fully understand sex, love, or sarcasm. Second, in the early episodes, Sheldon did not use his three-times knock (knock-knock-knock "Penny", et cetera) that has become one of the character's now well known idiosyncrasies that did not begin until midway through season one.
