The big bang theory is a US Sitcom, it is centered on five characters: two roommate geniuses, experimental physicist Leonard Hofstadter and theoretical physicist Sheldon Cooper, their neighbor across the hall Penny, an attractive blonde waitress and aspiring actress, and Leonard and Sheldon's equally geeky and socially awkward co-workers and friends Howard Wolowitz, an Aerospace engineer and Rajesh Koothrappali, a particle astrophysicist postdoc.
