<P> Sheldon was interested in science from an early age, and was a child prodigy, although due to his behavioral quirks and his lack of humility about his superior intellect, he was bullied by classmates and neighbors . Sheldon entered college at the age of eleven, and at age fourteen he graduated from college summa cum laude . (To this day, the college he went to for undergraduate studies has yet to be revealed, but he feels it is superior to his fellow Big Bang Theory colleagues' alma maters of Princeton (Leonard), MIT (Howard) and Harvard (Amy).) From then, he worked on his doctorate, was a visiting professor at the University of Heidelberg in Germany, was the youngest person at the time to receive the Stevenson Award, and has appeared on the cover of Journal of Physical Chemistry A. Sheldon is now a theoretical physicist doing research at Caltech, although he stated in Young Sheldon that he couldn't see himself living in California due to their carefree lifestyle . </P> <P> Sheldon is often described as a stereotypical "geek". He is usually characterized as being extremely intelligent, detail - oriented, eccentric, and occasionally disturbing . Despite his intelligence, he often displays childlike qualities, such as being extremely stubborn and a lack of common sense . It is claimed by Bernadette that the reason Sheldon is sometimes unpleasant is because the part of his brain that tells him it is wrong to be nasty is "getting a wedgie from the rest of his brain", although, in season 8's "The Space Probe Disintegration", Sheldon tearfully admits to Leonard that he is aware of his peculiarities and how his behavior comes across . The first four episodes of The Big Bang Theory portray Sheldon slightly inconsistently with respect to his later characterization, in which he is depicted as rather witty and sarcastic, and slightly flirtatious towards Penny in the pilot episode: according to Prady, the character "began to evolve after episode five or so and became his own thing". </P> <P> Sheldon possesses an eidetic memory and an IQ of 187, although he claims his IQ cannot be accurately measured by normal tests . He originally claimed to have a master's degree and two doctoral degrees, but this list has increased . Sheldon has an extensive general knowledge in many subjects including physics, chemistry, biology, astronomy, cosmology, algebra, calculus, economics, computers, vexillology, engineering, history, geography, linguistics, football, trains, Star Trek and in addition to being fluent in Klingon, has some knowledge of Finnish, Hindi and Mandarin . He also shows great talent in music, knowing how to play the piano (as does Parsons in real life), the bongos, the recorder, theremin (which Parsons learned to play in real life), showing some skill in Tuvan throat singing and also having perfect pitch . Although his friends have similar intellects to him, his eccentricities, stubbornness, and lack of empathy often frustrate them . Sheldon occasionally uses slang (in a very unnatural fashion), and follows jokes with his catchphrase "Bazinga!" which is now an officially registered trademark of Warner Bros. He is uncomfortable with human physical contact and has germophobia, which makes his exceptionally rare hugs extremely awkward and painful - looking . He also has hemophobia . Sheldon has difficulty coping when asked to keep a secret, when he is interrupted, or when he hears arguing . He is also a notary public and uses his knowledge in law and contracts usually for his own advantage and is always distressed when challenged in a legal aspect that he cannot logically defend . In his mannerisms, Sheldon also shows symptoms associated with obsessive - compulsive personality disorder . Whenever approaching a person's home, he must knock three times, then say the person's name, and must repeat this at least three times (where "The first one is traditional, but two and three are for people to get their pants on"), as a result of him walking in on his father with another woman when he was thirteen . Upon entering a person's home, he must select the proper seat before sitting down . When it is suggested by Penny that he "just sit anywhere", his response is "Oh, no, if only it were that simple!" This extends to his inability to accept change . His rigidity in maintaining homeostasis often causes him frustration . Because of his rigidity and stubbornness, only his mother and Bernadette--both possessing strong maternal personalities--have shown the ability to order him to do things . </P> <P> Like his friends, Sheldon is fond of comic books (especially the DC Universe), costumes, video games, roleplaying games, tabletop games, collectible card games, and action figures . Sheldon has restraining orders from his heroes Leonard Nimoy, Carl Sagan, and Stan Lee, as well as television scientist Bill Nye . Sheldon often wears vintage T - shirts adorned with superhero logos . One of his shirts is emblazoned with the number 73, and in the episode "The Alien Parasite Hypothesis" he explains that 73 is the 21st prime number, its mirror, 37, is the 12th prime number and its mirror (21) is the product of multiplying 7 and 3, also in binary, 73 is 1001001, a palindrome . The boys use video games like bowling and archery for "exercise" and use the traditional sport rules . </P>
