Main article: List of characters from The Big Bang Theory
  • Sheldon Cooper, Ph.D., portrayed by Jim Parsons, is a theoretical physicist. Originally from East Texas, he was a child prodigy, starting college at the age of 11, right after completing the fifth grade. He has an IQ of 187 and exhibits a strict adherence to routine; a lack of understanding of irony, sarcasm and humor; and a complete lack of humility.
  • Leonard Hofstadter Ph.D., portrayed by Johnny Galecki, is an experimental physicist with an IQ of 173 who received his doctorate when he was 24 years old. He shares an apartment with colleague and friend Sheldon Cooper and is the straight man of the series.
  • Penny, portrayed by Kaley Cuoco, is the attractive, blonde neighbor who lives across the hall from Sheldon and Leonard. She has aspirations of a career in show business, and has been to casting calls and auditions but has not been successful thus far. To pay the bills, she works as a waitress at The Cheesecake Factory. Her last name has never been revealed.
  • Howard Wolowitz, M.Eng., protrayed by Simon Helberg, works as an aerospace engineer. He is Jewish, and lives with his mother. Unlike Sheldon, Leonard, and Raj, Howard lacks a Ph.D. He defends this by pointing out that he has a master's degree in Engineering from the Massachusetts Institute of Technology and the apparatus he designs are actually built and launched into space, unlike the purely abstract work of his friends. He provides outrageous pick-up lines and fancies himself a ladies man with suitably unimpressed reactions from Penny; however, he has limited success with other women.
  • Rajesh Koothrappali, Ph.D., portrayed by Kunal Nayyar, originally comes from New Delhi, India. Known commnly as "Raj", he works as a particle astrophysicist at Caltech. He is very shy around women and is physically unable to talk to them unless he drinks alcohol. However, he has much better luck with women as opposed to his overly confident best friend Howard.
  • Leslie Winkle, Ph.D., portrayed by Sara Gilbert, is an experimental physicist who has casual sex with both Howard and Leonard during the show's airing. She does not get along well with Sheldon and frequently mocks him.

Episodes Edit

Season two begins to deal with character development, including Sheldon becoming more and more obsessive. Leonard and Penny's relationship takes a turn for the worse when they break up, but is quickly resolved. Soon their relationship progresses into a stronger friendship than before, while Sheldon and Penny's friendship slowly begins. In the season finale Penny hints at her true feelings for Leonard. Howard's character remains similar to that of season one in his attempts to seduce women, managing to start a short-lived sexual relationship with Leslie Winkle in the second half of the series, while Rajesh manages to briefly apologize to Penny without having consumed alcohol.
