Albert Einstein (born in Ulm, Kingdom of Württemberg, German Empire, March 14, 1879 - died in Princeton, New Jersey, USA, 18 April 1955 at the age of 76 years) is a theoretical physicist who is widely regarded as the greatest scientist of the century 20. He put forward the theory of relativity and also greatly contributed to the development of quantum mechanics, statistical mechanics, and cosmology. He was awarded the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect and "for his services to Theoretical Physics".
Having formulated the theory of general relativity, Einstein became world famous, an unusual achievement for a scientist. In his old age, his fame exceeded the fame of all scientists in history, and in popular culture, says Einstein is considered synonymous with intelligence or even genius. His face is one of the most recognizable in the whole world.
To appreciate them, a unit of the photochemical named Einstein, a chemical element named einsteinium, and a named asteroid 2001 Einstein.

Biography.
Youth and university.
Einstein was born in Ulm, in Württemberg, Germany, approximately 100 km east of Stuttgart. His father named Hermann Einstein, a salesman feather bed which then undergo electrochemical work, and his mother was Pauline. They were married in Stuttgart-Bad Cannstatt. Their family of Jewish descent; Albert schooled in Catholic school and the wishes of his mother he was given violin lessons.At the age of five, his father showed him a pocket compass, and Einstein realized that something in the room that "empty" acted upon the needle; she later describes this experience as one of the most evocative moment in his life. Although he made models and mechanical devices as a hobby, he is regarded as a slow learner, probably caused by dyslexia, shyness, or because the structure of the rare and unusual in his brain (examined after his death). He then was given an award for his theory of relativity because of this slowness, and said to think in terms of space and time from the other children, he was able to develop a more evolved intelligence. Other opinion, in the news lately, about her mental development is suffering from Asperger's syndrome, a condition associated with autism.
Einstein began to study mathematics at the age of twelve. There was a rumor that he failed in mathematics in his education, but this is not true; replacement in the assessment unnerve the following year. Two uncles helped develop his interest in the world of the intellect at the end of his childhood and early adolescence by making suggestions and books on science and mathematics. In 1894, due to his father's business failure electrochemical, Einstein moved from Munich to Pavia, Italy (near Milan). Albert stayed behind to finish school, finish a semester before rejoining his family in Pavia.
His failure in the liberal arts in the entrance test Eidgenössische Technische Hochschule (Swiss Federal Institute of Technology, Zurich) in the following year was a step back by his family sent him to Aarau, Switzerland, to complete high school, where he received a diploma in 1896, Einstein several sign up at the Eidgenössische Technische Hochschule. In the following year he took off his Württemberg citizenship and became stateless.
In 1898, Einstein met and fell in love with Mileva Marić, a Serbian who is a classmate (also a friend of Nikola Tesla). In 1900, he was awarded a degree to teach by the Eidgenössische Technische Hochschule and was accepted as a Swiss citizen in 1901. During this time Einstein discussed his interest in science to his close friends, including Mileva. He and Mileva had a daughter named Lieserl, born in January 1902. Lieserl Einstein, at that time, was considered illegal because the parents are not married.
Work and Phd.
Albert Einstein, 1905
At the time of graduation Einstein could not find a teaching job, keterburuannya as a young man easily angered professornya. The father of a classmate helped him get a job as a technical assistant examiner at the Swiss Patent Office in 1902. There, Einstein assessing the inventor's patent application for devices that require knowledge of physics. He also starts to realize the importance of application compared with poor explanations, and learn from the director how "to explain himself properly". He is sometimes correct their design and also to evaluate the practicality of their work.Einstein married Mileva on January 6, 1903. Einstein's marriage to Mileva, a mathematician. On May 14, 1904, the first child of this couple, Hans Albert Einstein, was born. In 1904, Einstein's position at the Swiss Patent Office became permanent. He earned his doctorate after submitting thesis "Eine neue Bestimmung der Moleküldimensionen" ("On a new determination of molecular dimensions") in 1905 from the University of Zürich.
In the same year he wrote four articles that provide the foundation of modern physics, without much scientific literature that he can appoint or many colleagues in science that he can discuss about his theory. Most physicists agree that three of those papers (on Brownian motion), the photoelectric effect and special relativity) deserved Nobel Prizes. But the only paper on the photoelectric effect would win the award. It is an irony, not only because Einstein is far better known for relativity, but also because the photoelectric effect is a quantum phenomenon, and Einstein became free from the street in quantum theory. What makes these papers remarkable is, in any case, Einstein boldly took an idea from theoretical physics to its logical consequences and managed to explain experimental results that had baffled scientists for decades.
He submitted a thesis-thesis to "Annalen der Physik". They are usually addressed to "Annus Mirabilis Papers" (from Latin: Year exceptional). Union of Pure and Applied Physics (IUPAP) plans to celebrate 100 years of the publication of Einstein's work in 1905 as a Year of Physics, 2005.
Brownian motion.
Albert Einstein, 1951 (72th birthday, was taken by Arthur Sasse, photographer)In the first article in 1905 called "On the Motion-Required by the Molecular Kinetic Theory of Heat-of Small Particles Suspended in a Stationary Liquid", includes research on Brownian motion. Using the kinetic theory of liquids which was controversial at the time, he established that the phenomenon, which is still less satisfactory explanation after a few decades after it was first observed, providing empirical evidence (on the basis of observation and experiments) on the reality of atoms. And also lend confidence in statistical mechanics, which at that time was also controversial.
Prior to this thesis, the atom is known as a useful concept, but physicists and chemists hotly debated whether atoms really were a tangible object. Discussion Einstein statistics about the behavior of atoms give experimenters a way to count atoms by looking through an ordinary microscope. Wilhelm Ostwald, a leader of the anti-atom school, later told Arnold Sommerfeld that he had converted to complete Einstein's explanation of Brownian motion.
Death.
On 17 April 1955, Albert Einstein experienced internal bleeding caused by the rupture of an abdominal aortic aneurysm, which had previously been done surgically by Dr. Rudolph Nissen in 1948. He took the draft of a speech he was preparing for a television appearance commemorating the seventh anniversary of the State of Israel with the condition in the hospital, but he did not live long enough to finish it. Einstein refused surgery, saying: "I want to go when I want. Bland to prolong life artificially. I have done my part, now it's time to go, I will do it elegantly ..." He died in Princeton Hospital, morning, at the age of 76, having continued to work until near the end.During the autopsy, the pathologist of Princeton Hospital, Thomas Stoltz Harvey, remove Einstein's brain for preservation without the permission of his family, in the hope that future neuroscience will be able to discover what made Einstein so intelligent. Einstein's remains were cremated and his ashes scattered at an undisclosed location.
In his lecture at Einstein's memorial, nuclear physicist Robert Oppenheimer, summarized his personal impression of Einstein: "He was almost wholly without sophistication and wholly without worldliness ... There was always with him a wonderful purity at once childlike and stubborn deep."
