Albert Einstein 3 Essay, Research Paper Albert Einstein Albert Einstein was born in Ulm, Germany on March 14, 1879, and died in 1955. He was an American physicist and Nobel Laureate, also known as the creator of the special and general theories of relativity and for his hypothesis concerning the particle nature of light. He is perhaps the most well known scientist of the 20th century. Albert Einstein spent most of his youth in Munich, Germany, where his family owned a small shop that manufactured electric machinery. He did not talk until the age of seven, but even as a youth he showed a brilliant curiosity about nature and an ability to understand difficult mathematical problems. At the age of 12 he taught himself geometry. Repeated business failure led the family to leave

Germany for Milan, Italy, when he was 15 yrs old. He then used the opportunity to withdraw from school. He spent a year with his parents in Milan, and when it became clear that he would have to make his own way in the world, he finished secondary school in Arrau, Switzerland, and entered the Swiss National Polytechnic in Zurich. Einstein often cut classes and used the time to study physics on his own or to play his violin. He passed all of his tests and graduated in 1900 by studying the notes of a classmate. His professors did not think highly of him and would not recommend him to a university. For two years Einstein worked as a tutor and substitute teacher. In 1902 he got a position as an examiner in the Swiss patent office in Bern. In 1903 he married Mileva Maric, who had been

his classmate at the polytechnic. They had two sons but eventually divorced. Einstein later remarried. In 1905, Einstein received his doctorate from the University of Zurich for a theoretical dissertation on the dimensions on the dimensions of molecules. He also published 3 papers of central importance to the development of the 20th century physics. In the first paper, Brownian Motion, he made a significant prediction about the motion of the particles that are randomly distributed in a fluid. These predictions were later confirmed by experiments. The second paper on photoelectric effect, contained a revolutionary hypotheses concerning the nature of light. Einstein not only proposed that under certain circumstance’s light can be considered as consisting of particles, but he also

hypothesized that the energy frequency of the radiation. The formula for this is E = hu, where E is the energy of the radiation. And h is a universal constant known as Planck s constant. And u, is the frequency of the radiation. This offer that the energy contained within a light beam is transferred in individual units. Virtually no one accepted Einstein s proposal. In fact, when the American physicist Robert Andrews Millikan experimentally confirmed the theory almost a decade later, he was surprised and somewhat troubled by the outcome. Einstein, whose prime concern was to understand the nature of electromagnetic radiation, subsequently urged the development of a theory that would be a fusion of the wave and particle models for light. Again, very few physicists understood or

were sympathetic to these ideas. Einstein s third major paper in 1905, On the Electrodynamics of Moving Bodies, contained what became known as the special theory of relativity. Since the time of the English mathematician and physicist Sire Isaac Newton, had been trying to understand the nature of matter and radiation, and how they interacted in some unified world picture. The position that mechanical laws are fundamental has become known as the mechanical world view, and the position that electrical laws are fundamental has become known as the electromagnetic world view. Neither approach, is capable of providing a consistent explanation for the way radiation (light for example) and matters interact. When viewed from different inertial frames of reference, an interaction viewed
