John Nash
John Forbes Nash, Jr. (born June 13, 1928) is an American mathematician whose works in game theory, differential geometry, and partial differential equations have provided insight into the forces that govern chance and events inside complex systems in daily life. His theories are used in market economics, computing, evolutionary biology, artificial intelligence, accounting, politics and military theory. Serving as a Senior Research Mathematician at Princeton University during the later part of his life, he shared the 1994 Nobel Memorial Prize in Economic Sciences with game theorists Reinhard Selten and John Harsanyi.

Nash is the subject of the Hollywood movie A Beautiful Mind. The film, loosely based on the biography of the same name, focuses on Nash's mathematical genius and struggle with paranoid schizophrenia.[1][2]

Early life

Nash was born on June 13, 1928 in Bluefield, West Virginia. His father, after whom he is named, was an electrical engineer for the Appalachian Electric Power Company. His mother, Margaret, had been a school teacher prior to marriage. Nash's parents pursued opportunities to supplement their son's education with encyclopedias and even allowed him to take advanced mathematics courses at a local college while still in high school. Nash accepted a scholarship to Carnegie Institute of Technology (now Carnegie Mellon University) and graduated with a Master's Degree in only three years.[3] Post-graduate life

Nash's advisor and former Carnegie Tech professor, R.J. Duffin, wrote a letter of recommendation consisting of a single sentence: "This man is a genius."[4] Nash was accepted by Harvard University, but the chairman of the mathematics department of Princeton, Solomon Lefschetz, offered him the John S. Kennedy fellowship, which was enough to convince Nash that Harvard valued him less.[5] Thus he went to Princeton where he worked on his equilibrium theory. He earned a doctorate in 1950 with a 28 page dissertation on

    In the movie, "A Beautiful Mind", John Nash displays classic positive symptoms of a schizophrenic. This movie does a fair job in portraying the personality and daily suffering of someone who is affected by the disease, although the film does not give a completely historically accurate account. In the film, John Nash would fall into the category of a paranoid schizophrenic, portraying all the symptoms that are typical for this illness. Nash suffers delusions of persecution, believing that there is a government conspiracy against him. He believes that because he is supposedly a secret agent working for the government breaking Soviet codes, and that the KGB was out to get him. In addition to these delusions, Nash experiences hallucinations which are shown from the moment that he starts college at Princeton University. He hallucinates that he has a roommate, when in reality it is uncovered later in the film that he was in a single occupancy room his entire stay at Princeton. Additionally, he frequently has conversations and takes advice from this imaginary roommate. He also imagines a little girl that is introduced to him by his alleged roommate. While going about his daily life, he is constantly surrounded by these inventions. These are classic positive symptoms of the paranoid schizophrenic, which are heavily supported by DSM-IV. Psychological predictions also agree with the behavior John Nash exhibited in the movie. This movie accurately teaches the public the positive affects of a schizophrenic. The movie does not portray schizophrenia as a split of Nash's personalities, rather a split from reality. He imagines other people and hallucinates vividly throughout the movie. Even at the conclusion of the movie, John Nash learns to accept and cope with his psychological disorder. He learns to ignore his hallucinations and is very careful about whom he interacts with. At…

    A Beautiful Mind was directed by Ron Howard and stars Russell Crowe. (IMDB.com, 2006) It depicts John Nash, a brilliant mathematician and economist who suffers from schizophrenia. Schizophrenia is defined as "impairments to the perception of reality." (Wikipedia.org, 2006) Specifically, John Nash suffers from paranoid schizophrenia. He encounters delusions and hallucinations but still has continuity of thought and does not display disorganized behavior that is seen in other types of schizophrenia. In the movie, Nash envisions several complex delusions. First would be his "college roommate and best friend," Charles. (IMDB.net) Nash also has complex delusions about being involved in secretive CIA decryption plots, and the climax of the film is when Nash believes he is being kidnapped by Soviet agents. Nash had been delivering what he thought were Soviet codes in daily newspapers and magazines, and delivering them to a drop-box. His wife retrieved all of the unopened letters from the drop-box, evidence to Nash that all of his "experiences" involving CIA agents and codes were just delusions. Insulin shock therapy was used in an effort to cure Nash in A Beautiful Mind, and he was prescribed to take an antipsychotic drug. The drug had side effects that placed strain on Nash's relationship with his wife and affected his intellect noticeably. Nash secretly stopped taking the drug and nearly drowned his infant…

    John Nash is the main character in the film A Beautiful Mind. Nash suffers from extreme schizophrenia and this radically affects his relationships with everyone around him. His wife, Alicia, must deal with the brunt of this, even before his condition was realized she would not often see him due to the fact that his hallucinations would keep him away from home for hours. When his schizophrenia was discovered, matters grew much worse, and thus was the inception of many years to come of intense emotional struggle. For months Alicia had to cope with watching her husband’s brutal treatment. Once released, he was put on a mental-suppressant that rendered him incapable of evaluating the realm of mathematic which he once had. Along with this came unwillingness towards activity, an inability to help with their new born baby, and a drastically decreased sexual drive. All this over many months and eventually years weighed very heavily on Alicia who now had to work to support them. This was bluntly illustrated during a scene in which John is unwilling to provide comfort for her at night and admits that the drugs are the reason for such. She finally breaks and goes to the bathroom in a destructive rage, breaking many things and screaming in despair. Moreover, his spontaneous dysfunction in the work place and eventual absence cause the burden of schizophrenia to spread also to his coworkers.…

    It seems he was destined for great things with his great grandfather having been a state legislator and mayor, his grandfather having been a vice president of a national bank and his father having been a prominent lawyer (Mirick, 1996).

    At the beginning of the movie “A beautiful Mind” (Grazer, 2001), John Nash is moving into a dorm room at Princeton University in 1947. John Nash appears slightly strange by exhibiting social withdrawal by avoiding people, along with a drop in school performance as he does not attend his classes. Soon visual hallucinations become apparent as Charles; his roommate makes appearances with his niece Marcie throughout the movie, along with Parcher, the head of the Department of Defense, who appears later in the movie as John Nash’s hallucinations become worse. John Nash begins to believe that he is employed by the Department of Defense, deciphering secret codes from the Soviets.…

    In “A Beautiful Mind,” John Nash is a smart man who soon develops schizophrenia. His schizophrenia consists of seeing people and believing people are out to get him. His schizophrenia becomes so bad that it burdens his wife and friends. It becomes difficult for his wife to love him and she is uncomfortable around him. At one point in the movie, his delusions cause him to almost drown his baby and cause him to knock his wife on the ground. John Nash, after going to a mental hospital, and seeing a therapist, still had bad delusions, but, he was so smart that he himself figured out how to ignore his delusions and continue on with life semi-normally. Although Nash still has schizophrenia he is still super intelligent and uses his intelligence too help the world around him. Nash goes on to win the Nobel Memorial Prize in Economics for his work on game theory, which helps with economics, political science, and psychology, as well as logic and biology. The Nobel Prize is an award for outstanding contributions to the field of economics, generally regarded as the most prestigious award for that field. Receiving this award proves that even though Nash has a terrible disorder he is still able to contribute a lot to the world around him.…

    John Nash, a brilliant man, wise beyond most men. I was very intrigued by the film’s portrayal of Mr. Nash. Despite having knowledge based on our textbook and power point slides concerning Schizophrenia, I lack knowledge and experience with someone who suffers from this complicated condition. This film depicted an in-depth, personal account of schizophrenia and the reality of their delusions (Howard, 2002). I can only imagine the pain and anguish one must feel when realizing that their delusions are not real. This film helped me to see Mr. Nash as a person dealing with this disease instead of a list of signs and symptoms from a textbook.…
