Best answer Fabre once observed a cricket lying on a tree. Someone misunderstood him as a thief and shouted to catch the thief. Another time he was Observing ants, people saw him observing ants from morning to when they went home, and they said he was crazy. Edison only attended elementary school for three months in his life. His knowledge was obtained through his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teachings from an early age. Edison, who was originally considered an imbecile, became a world-famous "invention king" when he grew up.

Edison has been curious about many things since he was a child, and he likes to experiment until he understands the truth. When he grew up, he devoted himself to research and invention based on his interests in this area. He established a laboratory in New Jersey and invented more than 2,000 things in his lifetime such as the electric light, the telegraph, the phonograph, the movie player, the magnetic separator, the crusher and so on. Edison's strong research spirit enabled him to make significant contributions to improving human life style.

"Waste, the greatest waste is time." Edison often said to his assistant. "Life is too short, you have to think of more ways to do more things with less time."

One day, Edison was working in the laboratory, and he handed his assistant an empty box without a lamp. Glass bulb, said: "You measure the capacity of the bulb." He lowered his head to work again.

After a long time, he asked: "What's the capacity?" He didn't hear the answer. He turned around and saw the assistant holding a soft ruler to measure the circumference and slope of the light bulb, and took the measured number. He leaned over the table and calculated. He said: "Time, time, why does it take so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to the assistant, and said: "Pour the water inside into the measuring cup, immediately Tell me its capacity."

The assistant immediately read the number.

Edison said: "This is such an easy measurement method. It is accurate and saves time. How could you not think of it? If you still calculate it, wouldn't it be a waste of time?"

The assistant blushed.

Edison murmured: "Life is too short, too short. Save time and do more things!"

Edison was a poor worker before he became famous. Once, his old friend met him on the street and said with concern: "This coat on you is worn out. You should get a new one."

"It will come in handy. No one knows me in New York?" Edison replied nonchalantly.

A few years later, Edison became a great inventor.

One day, Edison met that friend again on the streets of New York. "Oh," the friend exclaimed, "Why are you still wearing this shabby coat? This time, you have to get a new one anyway!"

"Is it useful? Everyone here already knows me." Edison still replied nonchalantly.

When Franklin was 7 years old, during a festival, the adults gave him a lot of money. Franklin planned to use the "big sum" to buy some toys at the store.

On the way, he saw a boy blowing a whistle very proudly. He was completely fascinated by the whistle, so he exchanged all his money for the boy's whistle. Back home, Franklin whistled proudly around the house, disturbing the whole family. After his family learned about his transaction, they told him that for the whistle, he paid four times more than its original price, and made him understand that the extra money could buy more and better things. .

Once in an arithmetic class, the teacher wrote "2+2=4" on the blackboard. Edison immediately stood up and asked: "Teacher, Why does 2 plus 2 equal 4?" This question stopped the teacher. He thought Edison was a troublemaker who was trying to get into trouble with the teacher. So, after three months of class, Edison was sent home by the teacher.

Edison loved big things when he was a child. nature. When he was 7 years old, he was sent to school by his mother. From then on, Edison would sit in the classroom every day and listen to Teacher Engel's lecture that 1 plus 1 equals 2, or 2 equals 1 plus 1.

Edison began to think about other things in class. For example, he thought: Since rubbing the fur of animals can generate electricity, then if you connect a wire to a cat and rub the cat's fur vigorously, can you generate electricity? Teacher Engel was most annoyed by students who couldn't concentrate in class, so he often scolded Edison, and Edison's academic performance became the last in the class. What made Teacher Engel even more irritated was that Edison also liked to ask weird questions that were difficult to answer. For this reason, the teacher told the parents that the student could not keep up with his studies and ordered the parents to take the child away. Edison's mother said: "According to my observation, Edison is quite smart..." Engel retorted: "No, no, no, he always comes last in the class! And he always asks ridiculous and weird questions. For example, he asked: 'Teacher, Why is 2 plus 2 equal to 4? "If 4 is equal to 4, do you still need to ask?" My mother said disapprovingly: "Teacher Engel, I don't think this question is ridiculous!" When Newton found an apple falling, he asked Asked a question: Why does the apple fall down instead of up to the sky? Such a seemingly absurd question became the first step for Newton to discover the law of universal gravitation. Can we say that Newton should not ask such a question? Engel couldn't answer for a while, but he still insisted on his opinion. He knocked on the table and said: "Who is Newton and who is your child? Can they be compared?"

The only formal education in Edison's life That's it. On the way home, Edison said to his mother something he had been thinking about for a long time: "Mom, when I grow up, I want to be the world's first-class inventor!" Answered by: GG Lu | Level 3 | 2009-4-9 20:35

The Story of Scientists

Marie Curie was a great physicist. She was born in Poland. Her real name was Marie. She was married to a young French scholar named Marie. El Curie, later known as Marie Curie. She and her husband *** worked together to discover and confirm the existence of radium. Next we will tell you how the Curies discovered the mysterious substance radium.

In 1898, French physicist Antoine Henri Becquerel discovered that uranium-containing minerals can emit a mysterious ray, but he failed to reveal the mystery of this ray. Marie and her husband Pierre Curie jointly undertook the work of studying this ray. They separated and analyzed pitchblende under extremely difficult conditions, and finally discovered two new elements in July and December 1898.

In honor of her native Poland, she named one element polonium and another radium, meaning "the substance that confers radioactivity". In order to obtain pure radium compounds, Marie Curie spent another four years (Marie CuI7e, 1867--1934) extracting 100 mg of radium chloride from tons of pitchblende slag, and initially measured the concentration of radium. The relative atomic mass is 225. This simple number embodies the hard work and sweat of the Curies.

In June 1903, Marie Curie obtained a doctorate in physics from the University of Paris with "Study on Radioactive Substances" as her doctoral thesis. In November of the same year, the Curies were awarded the David Gold Medal by the Royal Society. In December, they and Becquerel won the 1903 Nobel Prize in Physics.

In 1906, Pierre Curie died in a car accident. This heavy blow did not make her give up her persistent pursuit. She endured her grief and worked harder to complete their beloved scientific career. She continued the lectures given by her husband at the University of Paris and became the first female professor at the school. In 1910, her famous book "On Radioactivity" was published. With Mu, she collaborated with others to analyze pure metal radium and measure its properties. She also determined the half-lives of oxygen and other elements and published a series of important treatises on radioactivity. In view of the above-mentioned major achievements, she won the Nobel Prize in Chemistry in 1911, becoming the first great scientist in history to win the Nobel Prize twice.

This founder of radioactive science, who had experienced the hardships of science, became ill due to years of hard work and suffered from pernicious anemia (leukemia). She unfortunately passed away on July 4, 1934. She contributed greatly to the scientific cause of mankind. , dedicated a glorious life.

Dr. Benjamin Franklin is a famous American politician and scientist, publisher, printer, reporter, writer, philanthropist, diplomat and inventor. One of the important leaders during the American Revolution, he participated in the drafting of many important documents, and served as the U.S. ambassador to France, successfully gaining French support for American independence. Invented. Things he invented include bifocal glasses, fins, lightning rods, etc. Franklin is a Fellow of the Royal Society. He was also the first Postmaster General of the United States.

Franklin

Benjamin Franklin (1706-1790) was an American industrialist, scientist, social activist, thinker and diplomat in the 18th century.

He came from a humble background. He dropped out of school at the age of 10 and went home to work. At the age of 12, he worked as an apprentice and helper in a printing house. But he was diligent and studious. In addition to mastering printing technology, he also read extensively works on literature, history, and philosophy, taught himself mathematics and four foreign languages, and devoted himself to practicing writing. All of this laid the foundation for his many achievements in his life. A solid foundation.

In order to stand on his own in the society at that time, he founded his own business, a printing house, after many setbacks. Due to his hard work, credibility and attention to management, he not only stood firm in the fierce competition in the printing industry, but also expanded his business to several neighboring states and the West Indies, becoming a leader in the printing and publishing industry in North America.

He pays attention to observing natural phenomena and studying scientific issues. Starting from practice, he engaged in scientific experiments and observations, and answered the question of "what is electricity" in electricity. He called electricity in different states "positive electricity" and "negative electricity" and proposed the "first-flow theory" in electricity. , which revealed the essence of thunder and lightning phenomena in terms of atmospheric electricity, and was known as the "Second Prometheus". These epoch-making research results in electricity made him a world-famous first-class scientist. He also conducted research in optics, heat, acoustics, mathematics, oceanography, botany, etc., and had new stoves, lightning rods, electric wheels, three-wheeled clocks, bifocal glasses, automatic barbecue machines, glass instruments, overhead book takers, A series of inventions and creations such as new street lamps. Therefore, with only two years of elementary school education, he was awarded a master's degree or doctorate by six or seven universities, including Harvard University and Yale University in the United States, and Oxford University, Edinburgh University, and St. Andrew's University in the United Kingdom.

After Franklin became famous, he did a lot of work in the cultural dissemination and social welfare of the North American colonies. He has successively organized and established academic, cultural, medical and health organizations such as "*** Reading Club", "American Philosophical Society", "North American Association for the Advancement of Science", newspapers, libraries, bookstores, hospitals, universities, fire brigade, local militia organizations, etc. , firefighting, and security organizations and institutions; he also reformed the postal system of the North American colonies and established a unified postal system for the North American colonies. He was an outstanding social activist and became an influential figure in the North American colonies.

He is not only good at solving specialized problems in natural sciences and practical problems in social and political activities, but also often explores many philosophical and social issues. He is a deist and believes that the spirit is attached to matter; he believes that the cause of social poverty is that workers must feed parasites; he loves freedom and peace, opposes war, hates racial discrimination and slavery, and advocates safeguarding the interests of blacks and Indians. ． He was one of the most profound bourgeois liberal thinkers of his time.

He actively participated in the revolutionary movement and made significant contributions to the victory of the War of Independence and the initial construction of the American national system. contribute.

At the Albany Conference in 1754 attended by leaders of the North American colonies, he proposed the famous "Albany Union" plan, which was adopted by the conference and became the first to instill the idea of ??a great union of the United States of America into the colonies. People who go into the minds of the people.

In Pennsylvania, he always worked with the colonial people to fight against the rampant lawlessness of the owner group. In 1757, he went to London on behalf of the state parliament to petition the King of England, requiring the owners to pay taxes, and succeeded. In 1764, he went to London for the second time, asking the King to protect the interests of the colony, but to no avail. Afterwards, the British government intensified its suppression of the North American colonies, inspiring a stronger resistance struggle among the colonial people. Franklin's position completely shifted to the revolutionary side.

Pennsylvania was originally a proprietor's colony, land granted to William Bean by King Charles II of England in 1681. Later, William Bean's two sons inherited the property. The owners enjoyed the privileges of appointing officials including the governor, vetoing parliamentary bills, and being exempted from paying taxes in the colonies they owned.

In May 1775, he returned to America and immediately devoted himself to the revolutionary struggle. He served as chairman of the Pennsylvania Peace Committee, presided over the local military committee, and drafted the state constitution with President Paine; he attended the Second Continental Congress as a Pennsylvania representative and became one of the drafters of the United States Declaration of Independence; he served as the United States Postmaster General , organized the postal service during the war and achieved remarkable results;

When the U.S. military suffered repeated setbacks in combat, he consulted with Washington as a member of the three-person committee and decided to implement a general mobilization of 13 North American states, which enabled the War of Independence to last for 6 years.

In a situation where Britain was strong and the United States was weak, the colonial people must seek foreign aid. Franklin was ordered by the Continental Congress to send an envoy to France to win an alliance between the United States and France and to fight against the British. In the complicated diplomatic environment at that time that was not conducive to the United States, he used his belief that the United States would win, his perseverance and patience, and his clever and flexible diplomatic skills to take advantage of the conflicts among European countries and seize the favorable opportunity to form an alliance between the United States and France. The alliance secured a large amount of foreign aid in manpower, material and financial resources, ensuring the victory of the War of Independence. In the late war, he participated in and once presided over the peace negotiations between the United States and Britain, signed a peace treaty between the United States and Britain that was beneficial to the United States, and successfully completed the arduous wartime diplomatic mission. After the war, he became the first ambassador extraordinary and plenipotentiary of the new United States to France and stayed in France until returning to France in 1885.

After returning to China, he was elected governor of Pennsylvania for four consecutive years. At the U.S. Constitutional Convention, he was a member of the Constitution Drafting Committee. In order to mediate the differences of opinions among the representatives at the convention, he proposed the bicameral system of Congress, which became one of the basic national systems of the United States.

After 1788, he no longer held public office, but he still published political articles for the government to choose, and was committed to promoting the abolition of slavery.

On April 17, 1790, Franklin passed away. On the day of his funeral, as many as 20,000 people attended his funeral, which fully expressed the American people's mourning for him. At the same time, not only did the U.S. Congress decide to mourn for him for a month, but the French National Assembly also decided to mourn for him, indicating that he not only belonged to the United States, but also to the whole world

World-famous aerodynamicist Qian Xuesen

Qian Xuesen is a world-famous aerodynamicist, winner of the "Two Bombs and One Satellite Meritorious Medal", academician of the Chinese Academy of Sciences, and academician of the Chinese Academy of Engineering. Qian Xuesen made many groundbreaking contributions to aeronautical engineering theory as early as the 1930s and 1940s. Qian Xuesen proposed the "Opinion on Establishing my country's National Defense Aviation Industry" to the Chinese government on February 17, 1956, which was the first to propose an extremely important implementation plan for the development of China's rocket and missile technology. Qian Xuesen has long held technical leadership positions in rocket, missile and spacecraft development and made outstanding contributions to China's rocket, missile and aerospace industry.

Relativity, quantum mechanics and cybernetics are three important scientific achievements in the 20th century. In 1948, American scientist Vinod proposed cybernetics. Qian Xuesen made a comprehensive observation of the rapid development of control and guidance engineering technology practices after the Second World War, and used a sharper vision than others to discover and refine the concepts, principles, theories and methods that guide the design of control and guidance systems. Engineering cybernetics was created in the early 1950s. In 1954, a monograph on engineering cybernetics was published in the United States, and it was translated into multiple languages ??and published. The establishment of engineering cybernetics has promoted the development of my country's "two bombs and one satellite" and also promoted the development of electronic computers, nuclear energy, aerospace and optoelectronic technologies.

Qian Xuesen won the first prize of the Natural Science Award of the Chinese Academy of Sciences in 1957, the Rockwell Jr. Medal and the title of World-Class Science and Engineering Celebrity in 1979. In 1991, he was awarded the "National Outstanding Contribution Scientist" by the State Council and the Central Military Commission.
