Albert Einstein Albert Einstein was considered the greatest scientist of the 20th century and one of the greatest of all time. His discoveries and theories have greatly influenced science in many fields. Einstein was born in 1879 in Ulm, a city in Germany. As a boy, he was slow to learn to talk, but later in his childhood he showed great curiosity about nature and ability to solve difficult mathematical problems. After he left school, he went to Switzerland, where he graduated from the university with a degree in mathematics. In 1905, Einstein began to publish a series of papers which shook the whole scientific and intellectual world, and for the theories he established in the papers he won the Nobel Prize for Physics in 1921. Because Einstein was Jewish, when Hitler took over Germany in 1933, he had to leave the country and finally settled in the United States. There he continued his study on the structure of the universe until his death in 1955. Among the several important discoveries Einstein made in his life, the greatest is the creation of his famous Theory of Relativity

VOICE ONE: This is Steve Ember. VOICE TWO: And this is Sarah Long with the VOA Special English program, Explorations. Today we tell about a scientist who changed the way we understand the universe, Albert Einstein.VOICE ONE:Albert Einstein changed science.(All Pictures NASA) In the year Nineteen-Oh-Five, Albert Einstein published some important papers in a German scientific magazine. They included one of the most important scientific documents in history. It was filled with mathematics. It explained what came to be called his “Special Theory of Relativity.” Ten years later he expanded it to a “General Theory of Relativity.” Albert Einstein's theories of relativity are about the basic ideas we use to describe natural happenings. They are about time, space, mass, movement, and gravity.VOICE TWO: Albert Einstein was born in Ulm, Germany, in Eighteen-Seventy-Nine. His father owned a factory that made electrical devices. His mother enjoyed music and books. His parents were Jewish but they did not observe many of the religion's rules.Albert was a quiet child who spent much of his time alone. He was slow to talk and had difficulty learning to read. When Albert was five years old, his father gave him a compass. The child was filled with wonder when he discovered that the compass needle always pointed in the same direction -- to the north. He asked his father and his uncle what caused the needle to move.Their answers about magnetism and gravity were difficult for the boy to understand. Yet he spent a lot of time thinking about them. He said later that he felt something hidden had to be behind things.VOICE ONE: Albert did not like school. The German schools of that time were not pleasant. Students could not ask questions. Albert said he felt as if he were in prison. One story says Albert told his Uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. “You are looking for someone,” he said, “but you do not know who. Call him X. Find him by using the mathematical tools of algebra and geometry.”VOICE TWO: Albert learned to love mathematics. He was studying the complex mathematics of calculus when all his friends were still studying simple mathematics. Instead of playing with friends he thought about things such as: “What would happen if people could travel at the speed of light?” Albert decided that he wanted to teach mathematics and physics. He attended the Federal Polytechnic Institute in Zurich, Switzerland. He graduated with honors, but could not get a teaching job. So he began working for the Swiss government as an inspector of patents for new inventions. The job was not demanding. He had a lot of time to think about some of his scientific theories. VOICE ONE: From the time he was a boy, Albert Einstein had performed what he called “thought experiments” to test his ideas. He used his mind as a laboratory. By Nineteen-Oh-Five, he had formed his ideas into theories that he published.In one paper he said that light travels both in waves and in particles, called photons. This idea is an important part of what is called the quantum theory. Another paper was about the motion of small particles suspended in a liquid or gas. It confirmed the atomic theory of matter. The most important of Albert Einstein's theories published that year became known as his “Special Theory of Relativity.” He said the speed of light is always the same -- almost three-hundred-thousand kilometers a second. Where the light is coming from or who is measuring it does not change the speed. However, he said, time can change. And mass can change. And length can change. They depend on where a person is in relation to an object or an event.VOICE TWO: Imagine two space vehicles with a scientist travelling in each one. One spaceship is red. One is blue. Except for color, both spaceships are exactly alike. They pass one another far out in space.Neither scientist feels that his ship is moving. To each, it seems that the other ship is moving, not his. As they pass at high speed, the scientist in each ship measures how long it takes a beam of light to travel from the floor to the top of his spaceship, hit a mirror and return to the floor. Each spaceship has a window that lets each scientist see the experiment of the other. VOICE ONE: They begin their experiments at exactly the same moment. The scientist in the blue ship sees his beam of light go straight up and come straight down. But he sees that the light beam in the red ship does not do this. The red ship is moving so fast that th...
