Name: Dr. Sheldon Cooper MSc, PhD.
Occupation: Theoretical physicist.
Sheldon is the uber geek, he possesses a Master's degree and 2 PhDs, and conducts string theory research at Caltech. He shares an apartment with Leonard.
Unashamedly geeky, he has no qualms about speaking Klingon, he doesn't mind sharing details of his life that others might find embarrassing, such as a common activity being Klingon Boggle until the wee hours. He wears vintage t-shirts sporting superhero logos.
As a child prodigy, Sheldon was involved in numerous experiments as a child, such as his plan to provide free electricity for his town by building a nuclear reactor. A plan stopped only by government pen pushers claiming it's illegal to store yellow cake uranium in a garden shed! Sheldon started college at the age of 11, receiving his first PhD at 16.
While he might claim to be the perfect human specimen, Sheldon does have his faults - although he'd never admit it! He lacks empathy, is unable to discern sarcasm, doesn't like change, and has an inflated ego. He does not understand social norms, and makes little attempt to do so.
