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.

One of TV's Best Written Sitcoms
18 December 2007 | by (St. Louis Park, MN) – See all my reviews

I have seen a few episodes of the new CBS sitcom The Big Bang Theory and to me it's one of the best written sitcoms currently on network TV. The scripts are filled with scientific references some people might not understand but they are very witty. Johnny Galecki and Jim Parsons are definitely one of TV's newest comedy teams who have great chemistry and the addition of Kaley Cuoco as their neighbor, Penny brightens up the show. Let's not overlook the supporting cast with Simon Helberg as Wolowitz, who looks a little like Paul Reubens, the man behind Pee-Wee Herman and Kunal Nayyar as their friend from India.

If you watch the closing credits closely, you'll notice that there's a credit saying "Science Consultant." It's the first sitcom to employ one. It was a very good idea by the show's creator Chuck Lorre, who also is behind the CBS hit Two and a Half Men to hire one to bring scientific honesty into the show.

I hope The Big Bang Theory is around for several years. It has a solid future.
