Albert Einstein Work And Physics Essay, Research Paper Albert Einstein was a German-born American physicist best known for being the creator of the special and general theories of relativity and for this hypothesis concerning the particle nature of light. Einstein was born in Ulm on March 14, 1879 and spent his youth in Munich, Germany. Einstein didn t speak till the age of three. Despite this he even showed brilliancy as a child and understood difficult mathematical concepts. Around the age of 12, he taught himself geometry. Einstein hated school and when his family left Germany for Milan, Italy he dropped out. At this time he was only 15 years old and thought this suited him the best. Later on he thought it would be good if he went back to school. He finished secondary school in Arrau, Switzerland. After this he entered the Swiss National Polytechnic in Zurich. He didn t like how they taught class there and cut class to study his own physics. He graduated in 1900 by passing the final exam only because he studied classmates notes. In 1902 he was offered and took a position as an examiner in the Swiss patent office in Bern. In 1903 he married Mileva Maric. They had two sons and eventually divorced. In 1905 Albert Einstein received his doctorate from the University of Zurich for a theoretical dissertation on the dimensions of molecules. That year he also published articles on the same material. The first of the papers was on Brownian motion. The predictions he made were later proved true by his experiments. The second paper that Einstein wrote was on the photoelectric effect. This contained a “revolutionary hypothesis” concerning the nature of light. Einstein not only proposed that under certain circumstances light can be considered as consisting of particles, but he also hypothesized that the energy carried by any light particle, called a photon, is proportional to the frequency of the radiation. The formula created by Einstein for this is E=hu, where E is energy of the radiation and h is the universal constant known as Planck s constant. In this case u is the frequency of the radiation. This proposal contradicted a hundred-year-old tradition of considering light energy a continuing process. Almost no one accepted Einstein s proposal. When the American physics Robert Andrews Millikan experimentally confirmed the theory almost a decade later, he was surprised by the outcome. Another one of Albert Einstein s major papers was published in 1905. It was on “The Electrodynamics of Moving Bodies.” This contained what would later become known as his special theory of relativity. For hundreds of years physicists were trying understand the nature of matter and radiation. They were trying to understand how these two things interacted together. The position that mechanical laws are fundamental has become known as the electromagnetic world view. This, however, doesn t have the information to explain how matter and radiation interacted. In the springtime of 1905, after working on these problems for almost 10 years, Einstein realized that the real problem wasn t in the theory of matter, but the in a theory of measurement. At the heart of his new and special theory of relativity was that all measurements of time and space depended on the judgments as to weather two distant events could happen at the same time. This led him to base a theory based on two ideas: that physical laws are the same in all inertial reference systems. And the other is that the speed of light in a vacuum is a universal constant. This made him able to provide a correct description of physical events in different frames of reference without making special assumptions about matter or radiation. Not many people understood what Einstein was trying to get across. The reason not many people understood what he was saying was because it had to much equations and math in it. Also it was scientifically doubtful.
