The Big Bang Theory aired its first episode on 24th September 2007. The pilot episode was directed by James Burrows and written by Chuck Lorre & Bill Prady. The series kicked off by introducing our main characters Leonard Hofstadter and Sheldon Cooper as two intelligent young physicists who have a combined IQ of 360 believing that they are the only ones capable of understanding how the universe works.


While these 2 are shown to be highly intellectual and smart, they are highly awkward in the social atmosphere, especially with women. The latter is proven after Sheldon and Leonard’s daily routine is disrupted when Penny, an outgoing aspiring actress, moves into the apartment across the hall. Leonard shows interest in her and is smitten by her. On the other hand, we see Sheldon struggling to comprehend Penny’s presence and her social behavior, leading to humorous interactions between them.

The cast of The Big Bang Theory


The Big Bang Theory boasts an ensemble cast featuring Jim Parsons as Sheldon Cooper, a brilliant theoretical physicist who, while being socially awkward, has eccentric behavior and strict routines that add humor. Johnny Galecki plays Leonard Hofstadter, a more socially adept experimental physicist, and Sheldon’s roommate, who later in the series ends up in a relationship with his neighbor and friend Penny. Kaley Cuoco portrays Penny, the warm and outgoing aspiring actress who brings balance to the group with her street smarts and emotional intelligence.


Simon Helberg plays Howard Wolowitz, an aerospace engineer with a flamboyant personality and questionable fashion sense which gives his character quite a humorous touch. Out of the group of scientists, it's only Howard who does not have a PhD in his field for which he is always picked on by the gang. Kunal Nayyar plays Rajesh Koothrappali, an astrophysicist who forms a great comedic duo with Howard. While initially shown to be recurring characters, Mayim Bialik and Melissa Rauch join the main star cast as Amy Farrah Fowler and Bernadette Rostenkowski. While Amy, a neurobiologist, becomes Sheldon's girlfriend, Bernadette who is a microbiologist ends up in a relationship with Howard.
