The story of scientists' deeds

Stories of scientists' deeds (7 general stories)

The story of a scientist 1 Many students have scientists they admire, such as Nobel who invented the telephone; Einstein who invented the atomic bomb; Zhuge Liang, who invented the hole lamp, invented Malai, who fixed continuous shooting. ...

The scientist I admire is Edison who invented the electric light.

When Edison was a child, people called him Al. When I was a kid, Al liked to ask questions. He often asks some strange questions, which makes people feel very annoyed. Family members and pedestrians on the road are the objects of his questions. If he is not satisfied with the adults' answers, he will do the experiment by himself. For example, once Al saw a hen hatching eggs, he asked his mother why the hen always sat there all day. Mother told him that the hen was hatching eggs, and Al thought that if the hen could hatch eggs, so could I. A few days later, mom and dad found Al squatting in the wooden room, wondering what he was doing. When the family found Al hatching eggs, everyone burst into laughter. ...

Al went to primary school at the age of eight, but dropped out after only three months of classes. When Al is in class, his mother is often called to the school to talk to the teacher. This is because Al often asks some questions that the teacher thinks are strange. The teacher thought he was a mentally retarded child, so his mother decided to teach Al herself and was determined to make Al a great genius. In this way, Al began his self-study course, and Al was well taught by his mother. Later, Al also got permission to set up a laboratory in the basement. In order to prevent others from tampering with his experiments, Al also came up with a clever idea, that is, to put poison labels on the bottles of each experiment.

Edison liked to think about a series of problems with his distinctive big head since he was a child. When he saw the blacksmith burning iron in the blazing fire and hammering into various tools, he shook his head and asked one question after another: What is fire? Why does the fire burn? Why is fire red? Why is the fire so hot? Why does iron turn red after burning in a fire? Why is iron soft when it is red? Back home, little Edison started his first experiment in his own wooden shed. He brought hay and lit it. He wants to know what fire is. However, little Edison's first experiment led to a big fire, which destroyed the wooden shed at home.

Seeing this, I feel very ashamed. Because I don't insist on doing things like Edison: every time I encounter a little difficulty in doing math homework, I will think to myself: Who cares, I will do this at home! In this way, many problems were solved by my mother herself, and I didn't do anything. Now, I feel very sorry.

These stories of Edison's childhood tell us that everything needs hard work to succeed. Students, you must remember!

The Story of a Scientist 2 "The Story of a Scientist" is my favorite book to read during the winter vacation. It contains stories of some scientists, such as Darwin, Newton and Edison. After reading it, I think they are really great and powerful. Telegraph, telephone and electric light are so common and common in today's advanced technology that no one will be surprised. But do you know how important these things were to people at that time and how ecstatic they were? Humans thus remembered their inventor-Edison. What a good "king of invention", we should all learn from him.

When he grew up, Edison learned radio transmitting and receiving technology. In order to have a good rest at night and study and invent during the day, Edison designed a telegraph that can automatically send signals on time. This is the prototype of the telegram. Soon after, he improved the telegraph. After many tests, a new type of telegraph was successfully trial-produced. Edison looked at the machine he invented and smiled with relief. Although Edison studied for only three months, he loved science very much and made progress step by step. Edison did every experiment day and night. Although he failed many times, he never backed down. How many sleepless nights passed before he succeeded. Edison's greatest contribution to science and technology was the invention of the phonograph and the incandescent lamp. Edison studied hard all his life, was good at thinking and worked hard. At the age of 75, he signs in for work in the laboratory on time every day. For decades, he worked almost ten hours a day. In order to do experiments, Edison often stayed outside the laboratory and stayed awake for several days. I was so tired that I took a nap with a book as a pillow on the experimental table. One day, his friend made fun of him and said, "No wonder Edison knew so many inventions. It turned out that he was absorbing the nutrition in the book even when he slept. " Reading in the study for 3 to 5 hours at night, if the average person's life activity time is used to calculate, his life has doubled. So, on his 79th birthday, Edison proudly told people that I was 135 years old. If you were not diligent, how could Edison have achieved so much? I can't help but think of his famous saying: "Genius is 1% inspiration and 99% sweat!

Through Edison's story, I know that great scientists have made efforts, and they have been rewarded through their own efforts and invented things that benefit mankind. We now have a very good learning environment and very good teachers to teach us to learn knowledge, so we should study hard, learn skills well and make contributions to the country when we grow up.

Among these scientists, I admire Madame Curie the most. Madame Curie is a great female scientist. She has won many Nobel Prizes and medals awarded by advanced academic institutions in many countries. She studies hard and is never satisfied. After numerous experiments, she discovered the radioactive element radium. Radium was a sensational discovery in her life.

Although I don't know what elements are and what radioactivity is, I feel its weight by reading this book. In order to extract radium from 9000 kilograms of asphalt and uranium slag, Madame Curie had to boil the slag pot bite by bite and keep stirring. Bottles come in and out, little by little crystallization. Every day, she stood by the cauldron in overalls covered with dust and acid, filled with smoke, with tears in her eyes and itchy throat ... In this way, she struggled for 45 months, 1300 days. What hard work it is and what perseverance it takes! She is not only a world-famous scholar, but also a veritable laborer, housewife and mother of children!

Madame Curie worked hard to cultivate an undeveloped garden, and finally achieved one of the important achievements in the history of modern science-the discovery of radioactive element radium. How I long to swim in the ocean of knowledge, explore the world of science and uncover the secrets of nature like Mrs. Cheng Ju.

Because she won two Nobel Prizes, she is unique among female scientists. The reason why she has achieved so much is inseparable from her efforts. She and her husband used 800 tons of water and 100 tons of chemical reagent and found 1 gram of radium. People call her "the mother of radium". Because Madame Curie was busy doing experiments and didn't have time to see the children, she did experiments on dry bread with the children. Her selfless work spirit is really worth learning. It is not easy to get good grades; It is not easy to achieve something, you must work hard. As the old saying goes, "there is no limit to learning the sea, and there is no limit to learning the sea." . Therefore, from the usual time, we should ask ourselves to develop good study habits, be able to think independently, study hard and not be afraid of difficulties. In the future, I must learn from Madame Curie's indomitable spirit, study hard, be brave in practice, and strive to climb the scientific peak. I hope to be a scientist like Madame Curie when I grow up, and strive for the prosperity of the motherland and the scientific cause of the motherland for life!

As the saying goes, "Genius is one percent inspiration and ninety-nine percent perspiration" and "the future of science can only belong to the diligent and modest generation".

I must study hard, study hard and become a useful person!

Scientist's Tales 4 StephenWilliamHawking (English name: stephen william hawking) was born in Oxford, England on 1942 [1] year1October 8, which is the 300th anniversary of Galileo's death. Known as the king of the universe. Graduated from Oxford University and Cambridge University successively, and obtained a doctorate in philosophy from Cambridge University. He has been in a wheelchair for 46 years because at the age of 265,438+0, he unfortunately suffered from Luger's disease, which would make his muscles atrophy. Speech and question-and-answer can only be done by a speech synthesizer. He is a professor of applied mathematics and theoretical physics at Cambridge University in England, the most important contemporary general relativity and cosmologist, and one of the great men who enjoy international reputation in this century. He is also called the greatest scientist in the world and the king of the universe. Hawking, 1942 10, a scientist born in Oxford, England, happened to be born on the 300th anniversary of Galileo's death. In 1970s, he and Penrose proved the famous singularity theorem, for which they both won the Wolff Prize in Physics of 1988. He is therefore known as the most famous scientific thinker and the most outstanding theoretical physicist in the world after Einstein. He also proved the area theorem of black holes, that is, the area of black holes does not decrease with the increase of time. This naturally makes people associate the area of a black hole with thermodynamics. 1973, he considered the quantum effect near the black hole, and found that the black hole would emit radiation like a blackbody, and the temperature of the radiation was inversely proportional to the mass of the black hole, so that the black hole would gradually become smaller because of the radiation, but the temperature was getting higher and higher, and finally it ended in a last-minute explosion. The discovery of black hole radiation is of great significance, which unifies gravity, quantum mechanics and statistical mechanics.

The deeds of scientists Stephen Hawking is one of the great men with international reputation in this century. He is 60 years old and was born on the anniversary of Galileo's death. He is a professor in the Department of Applied Mathematics and Theoretical Physics of Cambridge University, and also the most important general relativity and cosmologist of our time. In 1970s, he and Penrose proved the famous singularity theorem, for which they both won the Wolff Prize in Physics of 1988. He is therefore known as the most famous scientific thinker and the most outstanding theoretical physicist in the world after Einstein. "He also proved the area theorem of black holes. Scientist Hawking's life is very legendary. As far as scientific achievements are concerned, he is one of the most outstanding scientists in history. His position is the highest professorship in the history of Cambridge University, that is, Lucasson Professor of Mathematics once held by Newton and Dirac. He holds several honorary degrees and is a member of the Royal Society. He was confined to a wheelchair for 20 years because of Luger's disease (amyotrophic lateral sclerosis), but he was physically and mentally disabled, which made him an advantage, overcame his disability and became a' supernova' in the international physics community. He can't write or even read clearly, but he transcends relativity, quantum mechanics and the Big Bang theory and enters the "geometric dance" to create the universe. Although he was so helpless in a wheelchair, his thoughts traveled brilliantly in the vast space and time, and solved the mystery of the universe.

Professor Hawking, a scientist, is a modern popular science novelist. His masterpiece is A Brief History of Time written in 1988, which is an excellent astronomical popular science novel. The author's imagination is rich, his ideas are wonderful, his language is beautiful and his words are meticulous, which is even more surprising. The outside world, the future changes are so magical and wonderful. This book has a cumulative circulation of 25 million copies and has been translated into nearly 40 languages. 1992 The film of the same name cost 3.5 million pounds. Scientist Hawking firmly believes that the basic ideas about the universe and the origin of life can be expressed without mathematics, and the world should be able to understand his profound theory through the audio-visual media such as movies. This book is a popular reading about exploring the nature of time and the frontier of the universe. It is the most important classic work about the scientific thought of the universe, which has changed the concept of the universe. As soon as this book was published, it caused great repercussions all over the world. A Brief History of Time is a landmark book for readers who prefer words to equations. She is good at being a contributor to human thoughts. This is a book that pursues knowledge infinitely and explores the essence of time and space.

Scientists' Tales 6 Scientist Stephen Hawking was born in Oxford on 194210.8, exactly 300 years after Galileo's death. Probably because he was born in the era of World War II, he was particularly fascinated by models when he was a child. When he was a teenager, he not only liked making model planes and ships, but also made many different kinds of war games with his classmates, reflecting his desire to study and manipulate things. This desire drove him to pursue a doctorate and made great achievements in the study of black holes and cosmology.

When scientist Hawking was thirteen or fourteen, he made up his mind to study physics and astronomy. At the age of seventeen, he won a natural science scholarship and successfully entered Oxford University. After graduating from bachelor's degree, he transferred to Cambridge University to study cosmology. Soon, he found himself suffering from Luger's disease, which can cause muscle atrophy. At first, he intended to give up the ideal of engaging in research, because doctors were helpless about the disease, but later, the rate of deterioration slowed down, so he regained his mood, overcame all difficulties, stood up from setbacks, bravely faced this misfortune and continued to indulge in research.

In 1970s, he and Penrose proved the famous singularity theorem, and won the Wolff Prize for Physics with 1988 * *. He also proved that the area of black holes will not decrease with time. 1973, he found that the temperature radiated by a black hole is inversely proportional to its mass, that is, the black hole will become smaller due to radiation, but the temperature will rise and eventually explode and disappear.

In the 1980s, he began to study quantum cosmology. At this time, there was something wrong with his movements. Later, because of pneumonia, he had a tracheal puncture operation, which made him unable to speak again. Now he is completely paralyzed, so he can only replace his feet with an electric wheelchair. He not only relies on computers and language synthesizers to speak and write, but also needs others to spread out every page on the table for him to read page by page in a wheelchair.

Hawking, a scientist, devoted his life to the study of theoretical physics and is considered as one of the most outstanding scientists today. His works include Time, Black Hole and A Brief History of baby universes and related articles. Although everyone thinks he is unfortunate, his achievements in science were obtained after his illness. With his indomitable will, he overcame his illness, created a miracle and proved that disability is not an obstacle to success. His love for life and enthusiasm for scientific research are worth learning from the younger generation.

7 The Story of Scientists' Deeds Eddie started his hard life at the age of 12. He worked as a newspaper boy on the train, learned the technology of delivering newspapers, and went to Boston and new york. It was not until he was 24 years old that he had his own factory and a happy family. Edison announced in 1878 that he would invent a safe electric lamp with soft light and low price. In order to find a suitable filament, Edison tried boron, ruthenium, chromium, carbon and various metal alloys, *** 1600 materials, which lasted 13 months, but all failed. Someone blew a cold wind and said that Edison "ate something that could not be chewed" this time.

A physicist who once worked for Edison called this experiment "looking for a needle in a haystack". However, Edison was not afraid of failure, insisted on the experiment and made up his mind to fish out a needle from the sea. Where there is a will, there is a way. 1879 65438+1October 10 At 5 pm on Sunday, Edison lit the light bulb with carbonized cotton thread. He personally observed and recorded it.

This time, the light bulb is bright and stable, 1 hour, 2 hours, 3 hours, ... The light bulb is always on. From 19 and 20 to 2 1, no one went to rest. Until 2 1 2 pm, Edison asked his assistant to raise the voltage a little, and the light bulb was brighter at the 45th hour. After a few minutes, the filament finally burned out. The New York Herald Tribune reported the success of the light bulb experiment in a full page. Edison got all the patents, and it is recognized that he invented the incandescent lamp. /kloc-On New Year's Eve in 0/879, Edison lit 60 light bulbs and hung them in Monroe Park. It was snowing heavily, and more than 3000 people came to visit it.

Edison was a pragmatic man. His motto is: "I seek what human beings need, and then I will take a step forward and try to invent it." Some people say that invention is the product of fate and Edison is a genius. Edison sighed and said, "Genius is one percent inspiration and ninety-nine percent perspiration!" "

When someone asked him how he persisted in inventing the light bulb after 654.38 million failures, he said that he had never failed in this process; On the contrary, he found 6.5438+0 million invalid methods. The 3,400 notes he wrote in his life recorded the inventive ideas and experiments in detail, which is a strong evidence of this passage. When Edison was 77 years old, someone asked him, "When will you retire?"

He blurted out, "The day before my funeral!" Once, someone asked Edison half jokingly, "Do you agree to give science ten annual holidays?" Edison replied seriously: "Science will never take a day off. It has been working every minute for hundreds of millions of years, and it will continue to work like this. " Indeed, Edison fulfilled his promise. He is over 80 years old. In order to "make more inventions", he is still working diligently to extract latex from weeds in his country.
