Sheldon Lee  Cooper . B.S.. M.S.. M.A.. Ph.D.. Sc.D. . is a Caltech theoretical physicist who shares an apartment with his colleague and best friend, Leonard Hofstadter. Originally from East Texas. Sheldon started college at the age of 11, receiving his first Ph.D. at the age of 16. Sheldon was involved in numerous experiments as a wunderkind. such as his plan to provide free electricity for his hometown by building a nuclear reactor - a plan stopped by government pen pushers claiming it's illegal to store Yellowcake uranium in a garden shed! Proudly geeky, he has no qualms about speaking Klingon. wearing vintage t-shirts sporting superhero logos, or spouting various historical and cultural anecdotes (e.g. his account of the introduction of the fork into Thailand). While he might claim to be the perfect human specimen, Sheldon does have his faults. Sheldon is characterized by a strict adherence to routine and hygiene; an overly intellectual personality; a tenuous understanding of irony, sarcasm and humor; and a general lack of humility or empathy, the former of which is demonstrated in the fact that he has no problem voicing to his peers his admiration for his superior intellect. These qualities, along with his penchant for pranks, are his character's main source of humor.
Sheldon was born in a Walmart in Galveston, Texas to Mary Cooper. and was officiated at the Lawrence Memorial Hospital, although he actually "fell out" of her at a K-mart in 1980. His father, George Cooper. died quite a while ago due to weight problems. He has a twin sister named Missy and an older brother named George Jr.. both described by their mother to be "dumb as soup." Sheldon was raised according to his mother 's Evangelical Christian beliefs, e.g. learning how to pray and becoming the co-captain of the East Texan Christian Youth Holy Roller Bowling League Championship team, seven-to-twelve year-old division. Meanwhile, he was forced to watch football by his father.
Like a typical nerd. Sheldon was bullied a lot during his childhood, mostly because he constantly expressed intellectual superiority to his peers (as he does now.) The bullying consisted of, but was not limited to, being beaten up, getting swirlies (even in church), noogies and wedgies, and having his personal belongings stolen. Sheldon even tells Amy Farrah Fowler that his childhood was "hell." Further anecdotes reveal he built a so-called "Sonic Death Ray " that didn't even slow down the neighbor kids (all it did was annoy their dog), and constructed an armed robot using integrated circuits from ceramic semiconductor substrates cooked in a modified Easy-Bake Oven. to defend his room from Missy (whose eyebrows were burned off as a result of a malfunction).
title "A Rederivation of Maxwell’s Equations Regarding Electromagnetism ". contains an approach that might change the way ferromagnetic hysteresis is calculated. Sheldon entered college at the age of eleven, right after completing the fifth grade. At age twelve, filled with disappointment at not receiving a titanium centrifuge to separate radioactive isotopes. he had to be flown to a hospital by helicopter to be treated for radiation damage following a mishap when he built a CAT scanner (which also resulted in the death of his sister's guinea pig, Snowball). He also, at this time, conducted experiments involving the height of stairs only to deduce that if a step on a staircase is two millimeters off or more, a person is likely to trip - his findings evidenced by his father breaking his clavicle. When Sheldon was thirteen, he attempted to build a nuclear reactor in order to provide free electricity for his town, but it failed after a government agent informed him that it was illegal to store Yellowcake uranium in a shed; he then had a big tantrum as a result. When Sheldon was fourteen years old, he graduated college summa cum laude . began graduate school. and was the youngest person at the time to receive the Stevenson Award at "fourteen and a half." He received his first doctorate at the age of sixteen and he then spent four years on his second dissertation. before obtaining his current position.
While it is never explicitly mentioned which university/universities Sheldon attended for his education, in "The Parking Spot Escalation ", Howard takes Sheldon's doctoral diploma from his office wall – "California Institute of Technology " is discernible, indicating that Sheldon studied at Caltech for at least one of his doctorates.
Sheldon's work on string theory is concentrated in several different directions. Notably, Sheldon has refocused his research from bosonic string theory to heterotic string theory. He wrote a paper on the decays of highly excited massive string states and illustrated mirror symmetry in the footnote of a publication. He determined that three-dimensional string-nets provided a unified picture of fermions and gauge bosons and reconciled the black hole information paradox with his theory of string-network condensates following a breakthrough in showing how neutrinos emerge from a string-net condensate. He also designated time for solving the spacetime geometry in higher spin gravity and worked on time-dependent backgrounds in string theory. specifically quantum field theory in D-dimensional de Sitter space.
Bridging theory and experiment, Sheldon is active in the field of particle physics phenomenology at high-energy colliders such as the LHC. Sheldon came close to figuring out why the Large Hadron Collider had yet to isolate the Higgs boson particle. Though, he was refused clearance for a very prestigious government research fellowship at a secret military supercollider. located beneath a fake agricultural station 12.5 miles southeast of Traverse City, Michigan.
In a similar capacity, Sheldon has made advances in theoretical plasma physics. studying turbulence and how it might be reduced to improve fusion reactor designs. Consequently, Sheldon worked with colleague Barry Kripke on the grant proposal for a new fusion reactor. as the university was only allowed to submit one proposal.
From nuclear theoretic calculations, he was thought to have discovered a method for synthesizing a new stable superheavy element. Despite the fact that a Chinese research team at the Hubei Institute for Nuclear Physics ran a test on a cyclotron with extremely promising results and reportedly found the
element, his calculations were wrong — the table from the Handbook of Chemistry and Physics in which he looked up the reaction rates of elements such as mendelevium. was in units of square centimeters (cm 2 ), which he misread as square meters (m 2 ), meaning he was off by a factor of 10,000. Sheldon surmised there must be some resonance between the elements he did not consider. In fact, someone from the Chinese research team added simulated signals to the data files, as Leonard Hofstadter re-ran the tests in his lab and disproved Sheldon's theory.
From a philosophical perspective. Sheldon has grappled with Gedankenexperiments (i.e. "thought experiments") to illustrate the quantum measurement problem. He produced four out of the five Gedankenexperiments he thought necessary for a cogent restatement of the quantum measurement problem, before the information was lost.
For his contributions to theoretical physics. he won a Caltech Chancellor's Award for Science. In "The Monopolar Expedition ", Sheldon received a grant from the National Science Foundation (NSF) to lead an expedition to the Magnetic North Pole in the Arctic Circle for an experiment in search of slow-moving magnetic monopoles. with Leonard, Raj and Howard as his support team. In the experiment, he detected what he believed was significant monopolar magnetic charge. validating one of the chief predictions of superstring theory. Though Sheldon publicly announced he had confirmed string theory and would receive a Nobel Prize, he learned that the charge detected was actually static electricity from the others' electric can opener, forcing Sheldon to issue a retraction to his announcement and severely damaging his reputation at the university. Soon after, National Public Radio with Ira Flatow from Science Friday interviewed him by phone from his office. regarding the recent so-called discovery of magnetic monopoles in spin ices. Based on his supposed discovery of a new stable superheavy element — which was actually a blunder — Sheldon appeared on Science Friday twice wherein a possible Nobel Prize in Chemistry was mentioned, had an article written about him in Physics Today and the National Science Foundation (NSF) wanted to give him a substantial grant.
Based upon a theory from Leonard, Sheldon wrote a paper detailing a theory that space-time is like a super-fluid. The paper was well received by the scientific community that included Professor Stephen Hawking .
In "The Anxiety Optimization ", Sheldon is trying to increase his working efficiency by keeping a high anxiety level while driving everybody crazy. The only good point is that he wants his friends to annoy him. Extremely tired, both Penny and Leonard put him to bed singing "Soft Kitty ".
Dr. Sheldon Cooper.
Aside from his characteristic idiosyncrasies. obsessions. and extreme narcissism. Sheldon is logical. He possesses an eidetic memory and an IQ of 187, although he claims his IQ cannot be accurately measured by normal tests. Sheldon has an overly extensive general knowledge, such as shown by his comments regarding various details of anecdotal knowledge (for instance, about the introduction of the fork into Thailand).
Sheldon also has qualities associated with being a prodigy, such as an inflated ego, social ineptitude, and an inability to relate emotionally with other people. Despite his intelligence, he has a distinct lack of emotional maturity and is often baffled by even the most common social interactions. He not only fails to understand the simplest sarcastic jokes made by his friends, but also regards their sadness over problems with blatant confusion.
Recently, he has begun to understand the concept of sarcasm, attempting unsuccessfully to employ it himself towards Penny in the second season, and successfully employing it towards his other friends in the third season. He appears to have a complete disinterest in romantic relationships, and his eccentricities, direct remarks, and demanding nature put him at odds with his own friends and especially Penny. Sheldon's expression of his more advanced intelligence has gotten him fired from his job, and even Leonard is surprised to learn that Sheldon is conceited enough to believe that Isaac Newton is intellectually inferior to himself. Sheldon hates it when someone stops him when he is trying to explain something. If this happens: a tic starts on his face until he can complete what he wants to say. He cannot and will not drive, and thus someone must always drive him unless in an extreme circumstance (like when he drives Penny to the emergency room in "The Adhesive Duck Deficiency ".)
He also shows symptoms of obsessive compulsive personality disorder and Asperger syndrome. e.g. when he finds Penny's apartment messy, he sneaks in during the night and cleans it up because he can't stand being in the same hallway with something so disastrous. He refuses to sit anywhere other than his designated spot on the couch and follow set routines, and the running gag of the show is that when he knocks on Penny's door, he has to say Penny's name every three knocks (he does this thrice every time). The series creators do not want to specifically identify Sheldon's specific psychological malady.
Sheldon occasionally uses slang (in a very unnatural fashion), and follows jokes with his catchphrase "Bazinga !" He is not entirely sure how to hug someone, and he avoids human contact whenever possible. Despite his ego-centrism, Sheldon appears to be somewhat aware of his social ineptitude, particularly his lack of understanding of sarcasm. He mentioned that he keeps a record of his daily conversations after Penny snapped at him and Leonard asked him why, to which he suggested that Leonard check his conversation records "to see if I messed up anywhere." Sheldon is also a difficult person to work with and generally displays apathy to the world around him. In "The Toast Derivation ", Sheldon was revealed to have criticized Bill Gates for focusing on his charity work rather than Windows Vista, a remark that earned him a punch in the face.
Sheldon does show on rare occasion interest in relationships, which was most prominently seen with Amy Farrah Fowler ; however, he does not express it directly, instead developing strange behavior patterns such as buying cats or refusing to open discussion to the matter.Source: bigbangtheory.wikia.com
