the show is centered on five characters: two roommate Caltech 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's and
Sheldon's equally geeky and socially awkward co-workers and friends
Howard Wolowitz, an Aerospace engineer and a non-PhD from JPL, and
Rajesh Koothrappali, a particle astrophysicist postdoc also working at
Caltech. The geekiness and intellect of the four guys are contrasted for
comic effect with Penny's social skills and common sense
