Stories about scientists’ deeds (7 general articles) Stories about scientists’ deeds 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 lantern, and Marais, who invented the fixed continuous camera...
The scientist I admire is Edison, who invented the electric light.
When Edison was a child, others called him Al. When Al was a child, Al loved to ask questions. He often asked strange questions that made people feel annoyed. Whether it was his family or pedestrians on the road, he would always ask questions. If he was dissatisfied with the answers given by adults, he would go there himself. Experiment, for example, once Al saw a hen hatching eggs, and he asked his mother why the hen always sat there all day long? His mother told him that the hen was incubating eggs, and Al thought that if the hen could do it, I could do it too. A few days later, his parents found that Al had been squatting in the lumber room, not knowing what he was doing. When the family found out that Al was incubating eggs, Everyone burst out laughing...
When Al was eight years old, he went to elementary school, but he dropped out of school after only three months of classes. When Al was in class, Mom was often called to school to talk to the teacher. This was because Al often asked questions that the teacher thought were strange. The teacher thought he was a retarded child, so Mom decided to teach Al herself and was determined to teach Al a great person. A genius, so Al started his self-study course. Al was taught very well 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 experimental products, Al He also came up with a clever idea, which was to put a poison label on each bottle of the experiment.
Since he was a child, Edison liked to use his distinctive big brain to think about a series of problems. When he saw the blacksmith burning iron in a blazing fire and then hammering it into various tools, he shook his big head and asked one question after another: What is fire? Why does fire burn? Why is fire red? Why is the fire so hot? Why does iron turn red after being burned in a fire? Why does iron become soft when it becomes red? After returning home, little Edison began his first experiment in his wooden shed. He brought hay and lit it, trying to figure out what fire was. However, little Edison's first experiment caused a fire and burned down the wooden shed at home.
I feel very ashamed when I see this. Because I am not as persistent in doing things as Edison: Every time I encounter a little difficulty when doing math homework, I think: What the hell, I will do this problem when I get home! In this way, many problems were solved by my mother herself without me doing them at all. Now, I feel very regretful.
These stories about Edison when he was a child tell us: You have to work hard to succeed in anything you do. Students, you must remember this! Stories of Scientists' Deeds 2
"Stories of Scientists" is one of my favorite books I read during the winter vacation. The book contains stories about Darwin, Newton, Edison and other scientists. After reading After that, I felt that they were really great and powerful. No one would be surprised how common and commonplace these things are in today's technologically advanced world, such as telegraphs, telephones, and electric lights. But do you know how crucial and ecstatic these things were to people at that time? Humanity therefore remembers their inventor - Edison. He is truly the "King of Inventions" and we should all learn from him.
When Edison grew up, he learned the technology of sending and receiving radio messages. In order to have a good rest at night and be able to delve into inventions and creations during the day, Edison designed a telegraph machine to automatically send signals on time. This was the prototype of the telegraph. Not long after, he improved the telegraph machine. After many tests, a new telegraph transmitter was successfully trial-produced. Edison looked at the machine he invented and smiled happily. Although Edison had only read books for three months, he loved science and moved forward step by step.
In every experiment, Edison worked day and night. Although he failed many times, he never gave up. After many sleepless nights, he succeeded. Edison's most significant contribution to science and technology was the invention of the phonograph and the incandescent electric light. Edison was diligent and studious throughout his life, good at thinking, and worked hard. At the age of 75, he still went to the laboratory to sign in on time every day. He worked almost ten hours a day for decades. In order to conduct experiments, Edison often stayed out of the house for several days in a row. Lab, no sleep. I was really tired, so I took a nap on the experimental table using a book as a pillow. One day, his friend joked to him: "No wonder Edison knew so many inventions. It turned out that he was absorbing the nutrition from books even while sleeping." Reading 3 to 5 hours in the study at night, if you use the activities of ordinary people throughout their lives, Calculating time, his life has been extended exponentially. Therefore, on Edison's 79th birthday, he proudly said to people, I am already 135 years old. Without diligence, how could Edison have such great success? , I can’t help but think of his famous saying: “Genius is one percent inspiration and ninety-nine percent perspiration!
Through Edison’s story, I know that great scientists are the ones who pay the most. We have worked hard and been rewarded through our own efforts, inventing things that benefit mankind. We now have a very good learning environment and very good teachers to teach us knowledge. Therefore, we should study hard and learn skills well. Grow up and contribute to the country.

Among these scientists, I admire Marie Curie the most. She is a great female scientist who has won several Nobel Prizes. She won many awards and medals from high-level national academic institutions. She worked hard and was never satisfied. After countless experiments, she discovered the radioactive element radium, which was a sensation in the world.
I don’t know what an element is or what radioactivity is, but reading this book made me feel its weight. In order to extract radium from 9,000 kilograms of asphalt and uranium slag, Marie Curie had to cook the slag in pots and pots. Boiling, stirring all the time; pouring bottles in and out, crystallizing bit by bit. She wears work clothes stained with dust and acid, standing next to the big pot, smoky and burning, Her eyes were watering and her throat was itchy... In this way, she struggled for 45 months and more than 1,300 days. It was such a heavy labor and required such perseverance. She was both a world-famous scholar and a veritable worker! , a housewife and mother of children!
Madame Curie worked hard to cultivate an unexplored garden, and finally achieved one of the most important achievements in the history of modern science - the discovery of the radioactive element radium. How much I long to swim in the ocean of knowledge like Mrs. Jucheng, explore the world of science, and uncover the secrets of nature one after another.
Because she has won two Nobel Prizes. She is unique among female scientists. The reason why she has achieved such great achievements is inseparable from her hard work. She and her husband used 800 tons of water and 100 tons of chemical reagents to discover it. 1 gram of radium, people call her "the mother of radium". Because Marie Curie was busy with experiments and had no time to look after her children, she carried her children and gnawed dry bread while doing experiments. Her selfless work spirit is really worth learning. It is not easy to get good grades; it is not easy to achieve something, and you must work hard. From normal times, I must develop good study habits, be able to think independently, study hard, and not be afraid of difficulties. In the future, I must learn from Marie Curie’s tenacious and enterprising spirit, study hard, be brave in practice, and strive to reach the peak of science. When I grow up, I want to be a scientific scholar like Marie Curie, and work hard for the prosperity of my motherland and the scientific cause of my motherland for the rest of my life!
As the saying goes: "Genius is one percent inspiration!" Plus 99% of sweat", "The future of science can only belong to the diligent and humble generation."
I must study hard, study hard, and become a useful person! Scientist Deeds Story 4
Stephen William Hawking, a scientist (English name: Stephen William Hawking), was born in Oxford, England, on January 8, 1942 [1], which was the 300th anniversary of Galileo's death. Known as the King of the Universe. He graduated from Oxford University and Cambridge University successively, and received a doctorate in philosophy from Cambridge University. The reason why he has been in a wheelchair for 46 years is because he unfortunately suffered from Lou Gehrig's disease, which causes muscle atrophy when he was 21 years old. His speeches and questions and answers can only be completed through a speech synthesizer. He is a professor at the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge in the United Kingdom. He is the most important contemporary general relativity and cosmologist. He is one of the internationally renowned great men of this century. He is known as the greatest living scientist. He is also known as King of the universe. Scientist Hawking King was born on January 8, 1942 in Oxford, England, on the 300th anniversary of Galileo's death. In the 1970s, he and Penrose proved the famous singularity theorem, for which they jointly won the Wolf Prize in Physics in 1988. He is therefore known as the world's most famous scientific thinker and most outstanding theoretical physicist after Einstein. He also proved the area theorem of a black hole, which states that the area of ??a black hole does not decrease as time increases. This naturally leads people to relate the area of ??a black hole to thermodynamics. In 1973, he considered the quantum effects near black holes and found that black holes emit radiation like a black body. The temperature of its radiation is inversely proportional to the mass of the black hole. In this way, the black hole will slowly become smaller due to radiation, while the temperature will become higher and higher. It ends with a last-minute explosion. The discovery of black hole radiation is of extremely fundamental significance, unifying gravity, quantum mechanics and statistical mechanics. Scientists' Deeds and Stories 5

The life of scientist Hawking is very legendary, and he has made great achievements in science. He was one of the most distinguished scientists of all time. He held the most prestigious professorship ever held at Cambridge, the Lucasian Professorship of Mathematics held by Newton and Dirac. He held several honorary degrees. He is a member of the Royal Society. He was confined to a wheelchair for 20 years due to Lou Gehrig's disease (amyotrophic lateral sclerosis), but he used his disability as an advantage and overcame it. He became a supernova in the international physics community. He could not write and could not even speak clearly, but he transcended the theories of relativity, quantum mechanics, and the big bang and entered the "geometric dance" of creating the universe. Even though he was so helpless. Even though he was sitting in a wheelchair, his thoughts brilliantly traveled through the vast space of time and solved the mysteries of the universe.
Scientist Professor Hawking is a modern popular science novelist. His masterpiece was written in 1988. "A Brief History of Time" is an excellent astronomical science novel. The author has rich imagination, wonderful ideas, beautiful language, and every word is exquisite. It is even more surprising that the changes in the future outside the world are so magical and wonderful. The book has sold 25 million copies and been translated into nearly 40 languages. In 1992, the 3.5 million-pound film of the same name was released. Scientist Hawking firmly believed that the basic ideas about the origin of the universe and life could be expressed without mathematics. , the world should be able to understand his profound and inscrutable theories through movies, an audio-visual medium. This book is a popular book on the forefront of exploring the nature of time and the universe. It is the most important classic work on contemporary scientific thinking about the universe. , it changed mankind's concept of the universe. "A Brief History of Time" has caused great repercussions around the world as soon as it was published. It is a landmark book for those of us who prefer to express with words rather than equations. .
She is the author of a person who has touched and contributed to human thought. This is a work of infinite pursuit of knowledge and a unremitting exploration of the mystery of the nature of time and space. Scientist's Deeds Story 6
Scientist Stephen Hawking was born in Oxford on January 8, 1942, which happened to be the 300th anniversary of Galileo's death. Perhaps because he was born during the Second World War, he was particularly fascinated by models as a child. When he was a teenager, he not only enjoyed making model airplanes and ships, but also made many different types of war games with his schoolmates, reflecting his desire to study and manipulate things. This desire drove him to pursue a PhD and make significant achievements in the study of black holes and cosmology.
Scientist Hawking had made up his mind to engage in research in physics and astronomy when he was thirteen or fourteen years old. At the age of seventeen, he received a scholarship in natural sciences and successfully entered Oxford University. After graduating with a bachelor's degree, he transferred to Cambridge University to study for a doctorate in cosmology. He soon discovered he had Lou Gehrig's disease, which causes muscle wasting. Because the doctors were helpless about the disease, he initially planned to give up his ideal of doing research. However, later the deterioration of the disease slowed down, and he regained his mood, overcome all difficulties, stood up from the setback, and faced this misfortune bravely. Continue your research.
In the 1970s, he and Penrose proved the famous singularity theorem, and both won the Wolf Prize in Physics in 1988. He also proved that the area of ??a black hole does not decrease with time. In 1973, he discovered that the temperature of black hole radiation is inversely proportional to its mass, that is, the black hole will become smaller due to radiation, but the temperature will increase, and eventually it will explode and disappear.
In the 1980s, he began to study quantum cosmology. At this time, he already had problems with his mobility. Later, he underwent tracheal surgery due to pneumonia, which made him unable to speak again. Now he is paralyzed and relies on an electric wheelchair to replace his legs. Not only does he need the help of computers and language synthesizers to speak and write, but even for reading, he has to have someone spread out each page of paper for him on the table for him to drive the wheelchair page by page. Go and see.
Scientist Hawking devoted his life to the research of theoretical physics and is known as one of the most outstanding scientists today. His books include "A Brief History of Time" and "Black Holes and Infant Universes and Related Articles." Although everyone thinks he is very unfortunate, his scientific achievements were achieved after he became ill. With his perseverance and unyielding will, he defeated the disease, 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. Scientist's Deeds Story 7
Eddie began his arduous career when he was 12 years old. He worked as a newsboy on the train, learned the technology of sending telegraphs, and went to Boston and New York until he was 24 years old. With his own factory and a happy family, Edison announced in 1878 that he would invent a soft, cheap, safe electric light. In order to find a suitable filament, Edison tried boron, ruthenium, chromium, carbon and various metal alloys, testing more than 1,600 materials, which lasted 13 months, but all failed. Some people blew a cold wind and said that Edison had "eaten something he couldn't chew" 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 and insisted on experimenting, determined to find the needle from the sea. Hard work pays off. At 5 pm on Sunday, October 10, 1879, Edison lit a light bulb using carbonized cotton filament. He personally observed and took notes.
This time, the light bulb was bright and stable, and it stayed on for 1 hour, 2 hours, 3 hours,... From the 19th, 20th to 21st, no one went to rest. Until 2 pm on the 21st, when the ignition reached the 45th hour, Edison asked his assistant to increase the voltage a little, and the bulb became brighter. After a few more minutes, the filament finally burned out. On December 21, the New York Herald Tribune devoted a full page to reporting in detail the news of the successful light bulb test. Edison received all the patents and is generally credited with inventing the incandescent light bulb.
On New Year's Eve in 1879, Edison lit 60 light bulbs and hung them in Menlo Park. It was snowing heavily at the time, and more than 3,000 people came to visit despite the heavy snow.
Edison was a practical person. His motto is: "I explore what mankind needs, and then I 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 blood and sweat!"
When someone asked him how he persisted during the 10,000 failures to invent the light bulb. , he said, he never failed in the process; instead, he found 10,000 ways that didn't work. The 3,400 notes he wrote throughout his life detailing invention ideas and experiments are strong evidence of this passage. When Edison was 77 years old, someone asked him: "When will you retire?"
He blurted out: "On the day before my funeral!" Once, someone asked Edison half-jokingly: "Will you retire?" Agree to give science a ten-year leave?" Edison replied seriously: "Science will never rest for a day. It has been working every minute for hundreds of millions of years and will continue to work like this." Edison fulfilled his promise. He was over 80 years old and still worked diligently to "make more inventions" and was committed to extracting latex from weeds in his country.
