Albert Einstein Of all the physicists that have existed in the twentieth century, one of them stands out above all the rest for very good reasons. This physicist's name is Albert Einstein. This man's hard work revolutionized the manner in which scientists of today think about the natural universe. As we, the population of the world, march into the new millenium, Einstein will be the man to whom we look for guidance in further understanding this wide, confusing universe that contains and directs us all. In March 14, 1879, in the city of Ulm in what was known as West Germany, this great physicist was born. His father was an unsuccessful manufacturer of electrical equipment. Due to his father's failure in his business, Einstein's family had to move to the city of Munich, and they later moved to Milan. As many people know today, Einstein was not originally thought to be the genius that he is, mostly because of his strong dislike to the rigid teaching methods of his teachers and his tendency to be disruptive. He excelled in science and math during his entire scholastic career, and he also studied these subjects these subjects in school. After becoming a high school dropout, because of his family having to move to Milan. In 1896, he revoked his German citizenship, and he was stateless up until the year 1901, which was when he became a citizen of Switzerland (2). Einstein worked a Swiss patent office from 1902 to 1909. In April 18, 1955, Einstein died a citizen of the United States of America (3). Within the year 1905, Einstein published four papers to the journal Annalen der Hooker 2 Physik, once one of the top physics journals in Germany. The first of these papers was published in the March of 1905. In this paper, Einstein began to explain quite a lot on the structure of light in such areas as how light contains a discrete amount of energy. Max Plank also had come to the conclusion that light should contain this discrete amount of energy, but Einstein went much farther than Plank did. Einstein explained how light is composed of independent particles, such as those in a gas, and he named these particles light quanta, today known as photons. This theory of photons contradicted the popular belief of light acting purely as an electromagnetic sine wave. With this paper, many problems encountered in scientific experiments involving light were resolved (1). This paper brings a sense of irony with it, because a while after this paper was published, a new branch of physics concerning the small particles of the universe, called quantum theory, came to be. Even though Einstein was the one who created the paper on which these physics were partially based, he refused to believe the principles of randomness involved in the quantum theory, stating, "God does not play dice." (4). Einstein published another paper to the journal Annalen der Physik in May of the same year. This paper was not as scientifically important as the last paper, but it retained its own significance nevertheless (1). In this paper, Einstein wrote about the well-known property of Brownian Motion explained by the kinetic theory (6). This motion can be described as the random jittering or atoms due to their retained heat. Einstein proposed a test to make sure that this theory was accurate. He said that if a scientist were to place or find visible particles in a clear liquid, the particles would act in accordance with their surroundings and randomly scuttle if the kinetic theory was true. If something else happens in the same situation, then the kinetic theory could very well be false. It so happened that the random jittering was seen, and the kinetic theory was reinforced (1). Einstein did not stop writing to Annalen der Physik with only two papers; he was on a roll now, and he was ready to write about his grandest discovery up to that point in his life. He would discover what is known today as the Theory of Special Relativity (1). He began on his journey to this theory when he observed some interesting properties in producing a current with a magnet and a coil. He found that it did not matter whether he moved the magnet or coil, because he measured a consistent current produced, as long as the objects themselves pass each other at the same speed. He then came to the realization that, no matter what the frame of reference is, the laws of physics will always hold. This statement is now known as the Theory of Relativity. Another physicist, Maxwell, had found in separate experiments that the speed of light was constant under all frames of reference. His results were not given their due credit for a long time, but when Einstein decided to mix his results with those of Maxwell's, he came to some very interesting conclusions. Einstein began to look at some odd situations. If a person imagines a clock, which is based on light shooting up and bouncing back for one click. If an astronaut were to stare at this clock going sideways on a spacecraft, he would see the path of the photon would travel up and down relative to the craft, and the path seen by the astronaut would then be triangle like. The path of the photon on the ship measured by the astronaut would, according to the Pythagorean Theorem, be longer than if measured from inside the spacecraft. Since the speed of light is constant for all observers, the time inside the Hooker 4 spacecraft must be running slower than normal when observed by the astronaut. With this being discovered, Einstein totally broke Newton's steady flow of time theory, and Einstein had proved time to be relative to speed. This meant that while Newton's equations did bring correct or very close to correct answers, the ones based on a constant flow of time are not entirely true. Most of the scientific community was unwilling to accept that Newton was wrong, but later testing proved Einstein to be in the right. When Einstein found that time is relative, he thought that since distance can be measured in how far something travels in a certain amount of time, distance is also relative. In short, an object is seen shorter (in the direction of motion) to an observer moving at a different speed relative to the object, compared to the length seen by an observer moving with the object. This effect is known as length contraction, and proves that length is also relative (6). Energy is the ability to do work, and that means all objects with any motion have the ability to do work, because their motion can be harnessed to speed up other objects. According to Einstein's previous equations, nothing can accelerate to the speed of light. The only way Einstein could figure that this could happen is that the force needed to accelerate the object increases. When mingled with Newton's law of force equals mass times acceleration, Einstein pondered on if the mass may be increasing to slow the acceleration. When he saw that mass was increasing with energy, he felt that there might exist a connection between the two. Eventually, Einstein found the answer. He published the answer in the last paper, sent in September of 1905, energy was equal to mass times the speed of light squared! Mass and energy are merely different Manifestations of the same thing. Einstein continued to move through life, but was bothered with his Special Theory of Relativity. He wondered what made inertial frames of reference (frames of reference at constant speed) so very different from a reference under acceleration. This thought led Einstein into one of his most complicated works yet: to generalize the theory of relativity to all situations, even those including gravity (6). He did not do so alone, but he also included his mathematical buddy Marcel Groomsman to help him (3). By late 1915, Einstein had published what is now known as the Theory of General Relativity (1). Out of his theory, a set of equations explaining how mass warp space-time was rendered. These equations came to be known as the Einstein Field Equations. The math involved in these equations was so complicated and long that only a select few could come close to working them, but no one could come close to solving the more complicated of these equations. Einstein felt that this was a serious pothole in the road of developing this theory. Since working the formulas proved so difficult, supercomputers are used today to create models of the gravitational forces predicted by Einstein, and numerical answers to variables in the the
