Because of that, my physics class researched and prepared this presentation on his life, his theories and his legacy to share with you. When you hear Einstein mentioned, I am sure that some image of him readily comes to mind.Perhaps it is of the down to earth professor that traded in his conventional coat and tie of the day and instead wore comfortable sweaters to work.</p><p>Or of a man that enjoyed recreation, such a sailing, and music, such as playing his violin, to relax and unwind.But more than likely It is of Einstein as more of a caricature than of a true person.The poster child for science. That of the wild haired mad scientist that Einstein has come to represent for most of us.</p><p>What ever your image is, we hope to help you learn more of Einsteins life and his theories. And help you to see just some of the impact he has had on our world.Albert Einstein was born in 1879 into a Jewish family in Germany. His mother was a musician and his father an engineer. Here, you see him pictured with is younger sister Maja.Einstein was initially suspected of being mentally retarded due to his delay as a child in developing speech. Once in school, He was dismissed by his teachers as being slow and lazy. Even though he generally got good grades and excelled in Math, Einstein did not enjoy school. His real studies were done at home with books on mathematics, physics, and philosophy. At age 15 out of rebellion, Einstein quit school. He later attended school in Switzerland and graduated from Zurich Polytechnic in 1900.</p><p>Einstein met his first wife while attending school in Switzerland. After have a daughter together in 1902, the couple were married. The fate of their daughter is unknown. She may have been adopted or perhaps died at an early age.They later had two sonsHans Albert, the oldest, became a hydraulic engineer and a professor at the Berkley. The youngest son, Eduard, developed schizophrenia.Mileva and Einstein divorced in 1919 after a lengthy separation. 1903 Marries Mileva Maric (1875-1948). They have two sons, Hans Albert (1904-1973), who became a successful hydraulic engineer, and Eduard (1910-1965), who fell prey to incurable schizophrenia. A daughter (1902-?) was born before the marriage and apparently put up for adoption--her fate is unknown. His parents were not happy with the marriage In 1905, while working as a patent clerk, or as he referred to it, as a patent slave, Einstein wrote 3 very important papers in physics. The first of these papers would earn him the Nobel prize.No one person, perhaps besides Sir Isaac Newton, has ever produced this quantity of scientific work in such a short amount of time. 1905 was dubbed his Miraculous Year.The topics of Einsteins papers were:The Photoelectric EffectBrownian Motion and AtomsAnd, Special Relativity</p><p>In his first paper, Einstein expanded on Max Planks work on light. The photoelectric effect is when light shown on a metal plate causes electrons to be released from the plate. Einstein realized that the intensity of the light did not effect the speed of the electrons But the color of the light didBlue light caused the electrons to be released at higher speeds than red light didEinstein concluded that light is not only a wave but a particle that carries energy, the amount of energy depends on the frequency of the wave</p><p>Einsteins second paper dealt with Brownian motion.Brownian Motion Realized Brownian Motion caused by movement of moleculesHis work helped prove the existence of the atom"... The physical theory of Brownian motion ended the skepticism about the existence of atoms and molecules as actual physical entities." [1] </p><p>Einsteins theory of special relativity deals with ideas that are difficult to understand One of these is Time Dilation:Einstein understood that the speed of light is constantFor the speed of light to be constant, time and distance must be able to changeThis leads to the Twin Paradox When one of the twin goes into space, he travels at a high speed relative to the earth twin; therefore, time for the the space twin slows down relative to the earth twinWhen the twin returns to earth, he is younger than the earth twinSpecial Relativity also deals with E = m c2the most famous equation in the worldMost people know this equation even if they dont understand it.It says that the amount of energy (either given off or absorbed) is equal to the change in mass multiplied by the speed of light squaredThe speed of light is a huge number and squared it is even largerTherefore, if a tiny mass is split it gives off a huge amount of energyEx. When a Uranium nucleus splits, the small mass is less than the original mass. The difference appears as energy in the form of light, heat and kinetic energyOn the flip side if energy is absorbed there is an increase in mass for example when a flower absorbs sunlight or energy, its mass increasesEinstein received his first teaching position in 1909 at the University of ZurichThen he became a professor at the university of Berlin in 1914.In 1915 Einstein completed his work on his theory of General Relativity. In which he talked about space wrapping around objects.In 1919 while doing research on a solar eclipse, a group of English scientist made observations that help prove his theory to be true. This lead to his worldwide fame. Einstein is Pictured here in 1919, the year before he won his Nobel prize.In 1919, after divorcing his first wife, Einstein remarried. You see him pictured here with Elsa, his second wife, who was also a distant cousin. In 1921, he was awarded the Nobel Prize in Physics for his work with the Photoelectric Effect. This same year Einstein and Elsa make there first trip to the United States where they were treated like royalty.In 1932 as Hitler and the Nazi party began to gain more and more power in Germany, Einstein was offered a position at the Institute of Advanced Study at Princeton. He was still a professor at the University of Berlin and planned to split his time between New Jersey and Berlin.But in 1933 when the Nazis gained control of the German Government, Einstein and Elsa left Germany to live permanently in New Jersey. Einstein was able to use his fame to help other Jews escape from Germany and from certain death. In 1939 when WWII started, Einstein feared that Germany would produce an atomic bomb to use against the Allied forces. He wrote a letter to President Roosevelt to warn him of this possibility. His letter helped to encourage the research that lead to the Manhattan project and the atomic bomb.In 1945 the allied forces dropped atomic bombs on Japan and ended World War II with much loss of life and destruction.Einstein was dubbed the father of Atomic Energy for his role in the nuclear research and the atomic bomb. He was never comfortable with this title.Einstein was a Pacifist. It has been said that the destruction and loss of life that he saw during WWI, caused him to speak out later against war and violence. After the use of the atomic bomb at the end of WWII, Einstein used his fame to speak out against its use and in support of worldwide peace. Here you see him pictured when he was doing just that. Einstein was also a Zionist, which is a person who believes in the Nation of Israel and the Jewish peoples right to that land. He believed that the Jews must live in peace though with the Arab nation.In 1952, Israel offered him the 2nd presidency of their reestablished nation; but even though he was honored, Einstein declined.During the last thirty years of his life, his contributions to science were not a great as the years between 1905 and his Nobel prize. Most of his work was done on trying find a unifying theory for all of physics which he was unable to come up with. Einstein died on April 18th, 1955 in Princeton, New Jersey. His ashes were scatter at some undisclosed place. His image and fame have yet to fade. In 2000, Einstein was named Time Magazines Man of the Century.</p><p>Today, Scientists are still working to find the unified theory that eluded Einstein at the end of his career. </p></li></ul>
