Thomas Edison, born in 1847 in the United States w w sea states. He read only three months of primary school. School the teacher said that he "stay foolish", relatives and friends are so called him. And his mother did not believe that, in person to be his teacher, guide him to read some books. Less than twelve years old, he read a lot of difficult to read books, his father also directed his studying Newton principle. Family education and influence, so that he had formed the spirit of hard work and perseverance. Edison liked science. He was very young in the cellar of his house, store hundreds of all kinds of test bottles, set up a small laboratory. He spent all his saving money at ordinary times, buy chemicals and chemical equipment. But the money alone is not meet the need of test, so he went to the train when paper boy. Every morning he boarded the bus, go home after 9 PM, make the test often late into the night to have a rest. Later, he found that there is a smoking room in the luggage compartment on the train unused, he put the home experiment moved to the cellar, insist on doing chemical experiments. Here, he also learned to use display here a printing machine, and can use telex number record local news, started a newspaper. This newspaper is very popular, have considerable market, at this time he was twelve years old. One day, the train shaking, luggage slide down, one of his experiment with phosphorus fell to the ground, carriage immediately caught fire. The fire was put out people rushed to the scene, but his ears deaf, conductor causes lifelong disability. Conductor is his "four-wheel laboratory" and "travel printing house is" all playing under the car. Difficulties and setbacks have no effect on Edison do science experimental determination, he built a laboratory in the home. By electricity, burned clothing, is often the case in the test. On one occasion, his face was nitric acid burn away to a shape. Even though this way, he never lose heart. Edison's efforts, the earliest greatly contributed to his later inventions. But, like other great inventor, Edison had walked through the road is not flat. He worked as a night telegraph. In the book, and libraries spend a lot of energy. But due to the several times of unemployment, finally have to go to New York to a friend. Edison to untold hardships, arrived in New York. This time, he is not even a penny in his pocket. He was hungry, so we have to ask people for a little bit of tea drink, this is the first meal after he went to New York. Here, he for a long time to find a friend, but his friend is also in unemployment. A mixture of Thomas Edison, hunger for RongYi compensated, ragged clothes and being looked down upon. Later, he was allowed to stay in a battery compartment. Just setting up a communication published price machine, in his arrival on the third day in the morning, the machine broke down, because he pay attention to study, soon to help somebody else repaired the machine, was to stay, this just found a job. Since this time, he worked hard, working with people reform, communication machine and the rising of the market. Before long, he opened a small factory producing this communication machine, step by step on the path of the scientific research. Story 3: Einstein's childhood story of the 20th century's greatest physicist Albert Einstein (Albert. Einstein) was born in Germany, on March 14, 1879, wu ear, in the southwest of the city, a year later with his family moved to Munich. Einstein's parents were jewish, father hermann Einstein and uncle Jacob goes into a for power and lighting system in the production of motor, arc lights and electrical instruments electric appliance factory. Bo Lin mother is a housewife, secondary education like music very much, in the Einstein taught him to play the violin at the age of six. Einstein was not lively, more than three years old, can't talk, parents were worried about he is a mute, took him to the doctor check. Okay baby Einstein is not dumb, but also is not very smooth until at the age of nine, every sentence of must go through difficult but serious thinking. At the age of four, five, Einstein once in bed, his father gave him a compass. When he discovered that the compass always points to the fixed direction, feel very surprised, think that there must be something deeply hidden behind this phenomenon. He is pleased to play the compass for several days, still cling to his father and uncle Jacob asked a series of problems. Although he even say the word "magnetic" is not good, but he stubbornly want to know why the compass to guide. This kind of deep and lasting impression, Einstein until sixty-seven at the age of the vivid memories of can also come out. Einstein read in primary school and middle school, my homework is usual. Because of his behavior slow, not love submission for contacts, the teacher and students all don't like him. Teach him Greek and Latin teacher to he is disgusting, has publicly scold him: "Einstein, you won't become useful when he grows up." And for fear of him in the classroom will affect other students, but want to put him out of the school gate. Einstein's uncle Jacob in electrical appliance factory specializes in technical aspects, Einstein's father is responsible for the business between us. Jacob is an engineer, they loved math, when small Einstein come looking for him to ask questions, he is always in very shallow popular language to introduce mathematical knowledge to him. Under the influence of the uncle, Albert Einstein earlier by the science and philosophy of the enlightenment. His father's business is not good, but it is a optimistic and kindness of heart, home to spend one night every week invited to Munich to study the poor students to have a meal, such as relief for them. There are a couple from Lithuania's jewish brothers Max and Bernard, all of them are medicine, like reading books, the interest is extensive. They were invited to Einstein's home for dinner, and sheepishly, black hair and brown eyes small Einstein became good friends. Max is Einstein's theory of "enlightenment" the teacher, he borrowed some popular science popularizer showed him. Max Einstein at the age of twelve, gave him a pielke's plane geometry textbook. Albert Einstein recalls this very little book holy said: "there are many assertions in this book, for instance, the triangle of the three high to us, though they are not obvious, but can be reliably prove it, so that any doubts seems to be impossible. The clarity and reliability left an indescribable impression on me." Einstein also fortunately from a great popular writings know the main achievements and methods in the field of natural science, popular science books not only enhance the Einstein's theory of knowledge, and strike a chord of the young man's curiosity, his thought of the problem. Einstein at the age of 16 to enter oneself for an examination of Zurich, Switzerland, the federal university of industrial engineering, but failed the entrance examination. He accepted the federal polytechnical university principal and famous physicist prof weber's advice, state high school in the city of Swiss law o finished high school courses, in order to obtain high school degree. In October 1896, Einstein got the Zurich university of technology school, study mathematics and physics in normal system. His injection of school education is very bad feeling, make people think it has no time, no interest to think of other problems. Fortunately, suffocation real scientific power of compulsory education, federal university of technology in Zurich, much less than any other university. Einstein's fully using the free air in the school, focusing on their beloved subject. In school, he read widely the helm hotz, Hertz, such as physics master's works, he is the most fascinating maxwell's electromagnetic theory. He has a habit of self-study ability, analyzing problem and the ability of independent thinking.
