Qian Xuelaisen

A missile launch test was about to begin, but the weather was very bad at the time. Whether it could be launched or not, the commander of the test base, The chief of staff and Qian Xuesen had different opinions. According to the regulations at the time, each launch report must be signed by three people in agreement, and then Marshal Nie Rongzhen was asked for approval. However, at that time, both the commander and the chief of staff said it could not be launched, but Qian Xuesen said with great confidence that it could be launched. This created a 2:1 situation, so the report signed by only Qian Xuesen was given to Nie Shuai. Unexpectedly, Nie Shuai readily approved the launch and said that if there were only those two signatures and no signature from Dean Qian, I would not dare to approve it. Do you think this missile was successfully launched? The result was that this missile was really successful.

Mrs. Reeves is a great physicist. She was born in Poland, and her real name is Mary. Married to the young French scholar Pierre Curie, she later became known as Madame 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 imparting 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.

3. A 200-word story about a famous scientific figure

British scientist Cavendish

It is said that Cavendish was very educated. But there is no British gentlemanly style. He was slovenly, with almost no clothes unbuttoned; he was not sociable, not good at talking, never married, and lived a strange reclusive life. In order to conduct scientific research, Cavendish converted the living room into a laboratory and placed many observation instruments next to the bed in the bedroom to observe celestial phenomena at any time. He received a large inheritance from his ancestors and became a millionaire. But he was not stingy at all. Once, one of his servants was in trouble due to illness and asked him to borrow money. He did not hesitate to write a check for ten thousand pounds and asked if it was enough. Cavendish loved books. He numbered his large collection of books by category and managed them in an orderly manner. Whether borrowing or even reading by himself, he performed the registration procedures without exception. Cavendi may be regarded as a scholar who lived and worked until he was old. He was still doing experiments until he was 79 years old and on the eve of his death. Cavendish received many nicknames in his life, including "Frankenstein", "Science Giant", "The Richest Scholar, the Most Learned Rich", etc. [2]

Treat fame and fortune as floating clouds

Once Cavendish attended a banquet, a scientist from Austria flattered Cavendish in person. Feeling embarrassed, and then at a loss, I finally couldn't sit still and stood up, rushed out of the room, got on the carriage and went home. Cavendish was taciturn and would often sit by without saying a word to the visiting guests, thinking about scientific issues in his mind, which embarrassed and disappointed some literati. He devoted his life to scientific research and achieved fruitful results, but he only published two unimportant papers. (Actually, it was because he was withdrawn and shy to the point of being "pathological" that even he and his housekeeper needed to communicate by letter; even when attending the weekly gatherings held by Banks at that time, all participants were required to He doesn't exist, and when asking for his advice you need to speak as if there is no one around, so you may get a vague answer or an angry scream)

His Laboratory

To commemorate this great scientist, people specially erected a monument for him. Later, his descendant S.C. Cavendish, the eighth Duke of Devonshire, donated his property to Cambridge University and built the laboratory in 1871. It was originally a teaching laboratory of the Department of Physics named after H. Cavendish. , the laboratory later expanded into a scientific research and education center including the entire Department of Physics, and was named after the entire Cavendish family.

The center focuses on independent, systematic, and group-based pioneering experiments and theoretical explorations, among which key equipment is promoted to be self-made. This laboratory has made great contributions to the advancement of physical science. In the past 100 years, the Cavendish Laboratory has produced 26 Nobel Prize winners. Maxwell, Rayleigh, J.J. Thomson, Rutherford and others have chaired the laboratory.

The Sleeping Manuscript

After Cavendish died in 1810, his nephew Qi Zhi put the 20 bundles of experimental notes left by Cavendish intact in the bookcase , no one touched it. Who would have thought that the manuscript had been kept in the bookcase for 70 years, until 1871, when Maxwell, another master of electricity, applied to be a professor at Cambridge University and was responsible for planning the establishment of the Cavendish Laboratory. These notes full of wisdom and painstaking efforts were obtained. A chance to return to the human world. Maxwell carefully read the work of his predecessors 100 years ago, and could not help but be shocked. He repeatedly said in admiration: "Cavendish may be the greatest experimental physicist in history. He anticipated almost all the great facts in electricity. These facts later became famous throughout the world through the works of Coulomb and the French philosopher." After that, Maxwell decided to put aside some of his research topics and painstakingly compiled these manuscripts, so that Cavendish's glorious ideas could be passed down. It is truly a masterpiece, a romance between two generations. It is nothing less than a good story in the history of science.

Focused and shy

Cavendish also participated in some social activities. The famous naturalist Joseph Banks held a weekly gathering of scientific celebrities at his home, and Cavendish would also attend. Banks specifically warned others not to get close to the man in the corner. If he expressed his opinion on a certain issue, people would wander around him pretending not to care, and pretend not to hear him. If the issue being discussed has nothing to do with science, people will hear a sudden exclamation behind them, and turn around to see Cavendish running towards another, quieter corner.

4. A 200-word inspiring story of a scientist

Scientist Hawking’s learning ability did not seem to be strong when he was a child. He learned to read very late, and his grades in the class never improved after school. He was not in the top 10, and because his homework was always "very untidy", his teachers felt that he was "hopeless", and his classmates also regarded him as an object of ridicule.

When Hawking was 12 years old, two boys in his class bet with a bag of candy that he would never become successful. His classmates sarcastically nicknamed him " Einstein". Unexpectedly, more than 20 years later, the little boy who was not outstanding at that time really became a master figure in the world of physics. What is the reason for this?

It turns out that as he gets older, little Hawking becomes interested in how everything works. He often takes things apart to get to the bottom of things, but after reassembling them When he returned, he was helpless, but his parents did not punish him for it. His father even served as a "coach" for him in mathematics and physics.

When he was thirteen or fourteen years old, Hawking found that he was very interested in the study of physics. Although physics in middle school was too easy and too simple, and seemed particularly boring, he believed that it was the most basic science. It will hopefully solve the problem of where people come from and why they are here. From then on, Hawking began his real scientific exploration.

The story of Bi Sheng’s movable type printing

In the early days of printing, the book was engraved on the whole Printed on wooden boards. I heard that my senior brother Bi Sheng invented movable type printing, and the printing efficiency suddenly increased dozens of times. The juniors all learned from my senior brother.

Bi Sheng demonstrated and explained at the same time, introducing his invention to his juniors without reservation.

He first made small squares from fine clay, carved convex backhand characters one by one, burned them hard with fire, and placed them in wooden grids according to the rhymes. Then spread adhesive (rosin, wax and paper ash) on an iron plate, arrange the character prints one by one according to the paragraphs, then put an iron frame around it and heat it with fire. When the adhesive cools slightly, use a flat plate to flatten the layout. After it is completely cooled, you can print. After printing, the printing plate is dried with fire to melt the adhesive, and the movable type is removed one by one and saved for the next typesetting.

The junior fellow students couldn’t help but admire it. A junior brother said: "There are more than 5,000 volumes of the Tripitaka, and 130,000 wooden boards were carved, which cannot fit in a room. It took many years of hard work! If I use my brother's method, it can be completed in a few months. Brother, How did you come up with such a clever method?"

"My two sons taught me!" Bi Sheng said.

"Your son? How is that possible? They can only 'play house'."

"You're right! They just rely on this 'playing house'." Bi Sheng He smiled and said, "Before the Qingming Festival last year, I took my wife and children back to my hometown to worship our ancestors. One day, my two sons played house and made pots, bowls, tables, chairs, pigs, and people out of mud. They arranged them as they pleased. Back and forth. Suddenly, my eyes lit up, and I thought, why don’t I also play house: I can carve single-character seals in clay, and I can arrange them into articles. Haha, isn’t this what my son taught me? "Really?"

The brothers also burst out laughing after hearing this.

"But every child has played this house, and all the senior brothers have seen it. Why are you the only one who invented movable type printing?" The same junior brother asked.

After a while, the master spoke: "Among your brothers, Bi Sheng is the most thoughtful. He has been thinking about new ways to improve work efficiency for a long time! Three feet of ice does not freeze in a day. "

"Oh——!" The brothers suddenly understood.

6. The story of a scientist in 200 words

One morning in August 1862, Edison was selling newspapers at a small station. Looking up suddenly, he saw a three or four-year-old boy squatting beside the railway track and playing with stones. A freight train was speeding towards him. Edison said "Oh!", threw down the newspaper, rushed down the platform desperately, and snatched the child out. At this time, the train whizzed past his ears. How dangerous! Edison fell to the railroad track while holding the little boy. His face and hands were cut, but the child was saved.

The little boy's father is called McKenzie, who is the webmaster of this station. He is an excellent telegraph operator. McKenzie saw this thrilling scene with his own eyes and was so moved that he could not speak coherently: "Thank you... thank you, thank you for saving... saving my child!"

Edison didn't care. Smiling, he picked up the newspaper from the ground, patted the dust off his body, boarded the train and left.

The next day, when Edison's train entered the station, McKenzie was already waiting on the platform. He said to Edison very sincerely: "I have nothing to reward you. I heard that you are very interested in telegraphy. If you are willing, I can teach you the technology of sending and receiving telegraphs and make you a telegraph operator." These words It's right in the heart of little Edison. He happily accepted McKenzie's kindness and followed him to learn the technology of sending and receiving telegraphs.

Edison was very attentive in his studies and made rapid progress. In just three months, he was already very proficient in sending and receiving telegraphs. McKenzie recommended him to work as a telegraph operator at the train station. This unexpected learning opportunity laid a good foundation for Edison's future great inventions. Base.

Newton's Story

One evening, Newton, who was deep in thought, subconsciously walked towards the apple orchard in his backyard. In the garden, the apple trees were covered with ripe apples, and the air was filled with the refreshing fruity fragrance. Newton was completely unaware of this.

Suddenly, there was a "click" sound, and a ripe apple on the tree was blown to the ground by the wind. Newton's thoughts jumped: Hey! Why don't apples fall to the sky? Is it the earth's gravity that is attracting it? !

Newton immediately made the association and extended it. It is thought that the force by which the earth attracts the apple is the same as the force by which the earth causes the moon to revolve around itself, and the force by which the sun causes the planets to revolve around itself. The force of gravity was derived, and people called it "gravity."

7. A short story about scientists of more than 200 words

George Simon Ohm was born in Erlangen, Germany. His father was a locksmith. His father taught himself mathematics and physics and taught it to Ohm as a boy, arousing Ohm's interest in science. At the age of 16, he entered the University of Erlangen to study mathematics, physics and philosophy. Due to financial difficulties, he dropped out of school and did not complete his doctoral studies until 1813. Ohm was a man of great genius and scientific ambition. He had been a middle school teacher for a long time. Due to the lack of materials and instruments, it brought many difficulties to his research work, but he always persisted in scientific research in a lonely and difficult environment. Research and make your own instruments.

Ohm studied the current in a wire. He was inspired by the heat conduction law discovered by Fourier. The heat flow between two points in the heat-conducting rod is proportional to the temperature difference between the two points. Therefore, Ohm believed that the phenomenon of electric current was similar to this, and speculated that the current between two points in the wire may be proportional to some driving force between them, which is now called electromotive force. Ohm spent a lot of energy on research in this area. At first he used a voltaic pile as a power source, but the effect was not good because the current was unstable. Later, he accepted others' suggestions and switched to using a thermoelectric battery as the power source, thereby ensuring the stability of the current. But how to measure the magnitude of the current was still an unsolved problem at the time. At first, Ohm used the thermal effect of electric current to measure electric current using the method of thermal expansion and contraction, but this method was difficult to obtain accurate results. Later, he combined Oersted's discovery of the magnetic effect of current with the Coulomb torsion scale, and cleverly designed a current torsion scale, using a twisted wire to suspend a magnetic needle, so that the current-carrying wire and the magnetic needle were placed parallel to each other along the meridian direction; Use a bismuth and copper thermoelectric battery, immerse one end in boiling water and the other end in crushed ice, and use two mercury tanks as electrodes connected to copper wires. When a current flows through the wire, the deflection angle of the magnetic needle is proportional to the current in the wire. He published the experimental results in 1826. In 1827, Ohm summarized his experimental rules into the following formula in his book "Mathematical Research on Circuits": S = γE. In the formula, S represents the current; E represents the electromotive force, that is, the potential difference between the two ends of the wire, γ is the conductivity of the wire to current, and its reciprocal is the resistance.

In the early days of the discovery of Ohm's law, many physicists were unable to correctly understand and evaluate this discovery, and were met with skepticism and sharp criticism.

The research results were ignored and the economy was extremely difficult, which made Ohm mentally depressed. It was not until 1841 that the British Royal Society awarded him the highest honor, the Copley Gold Medal, that he attracted the attention of the German scientific community.

Ohm also proved in many of his works that: resistance is directly proportional to the length of the conductor and inversely proportional to the cross-sectional area and conductivity of the conductor; in the case of a stable current, the charge is not only on the conductor on the surface and across the entire cross-section of the conductor.

To commemorate him, people named the physical quantity unit for measuring resistance after Ohm.

1. Newton’s story

Newton is a world-famous scientist. Newton loved animals when he was a child. Once, his friend gave him a dog and a cat. Newton was very happy to receive the gift and took good care of his new friends. In order to make it easier for the dog and cat to enter and exit the room, Newton dug two holes near the door. , one big and one small. Someone asked him, why did you dig two holes, one big and one small?

Newton replied: "Can a dog pass through a cat hole?" Newton's childhood was unfortunate. His father died three months before he was born. When she was two years old, her mother remarried to a neighboring village. Newton had to depend on his grandmother. He never spent money recklessly. His only hobby was to do some small crafts. He gathered his pocket money and bought tools such as saws and hammers. After school, he would hide in the house and knock on things.

Newton was very focused when he was studying. Once when I was boiling eggs, I was thinking about mathematical formulas and mistakenly thought my watch was an egg and threw it into the pot. Another time, I had been working on a problem since morning and even forgot to eat lunch. When he felt hungry, it was already dark. As he stepped out of the study room, he felt a gust of breeze and felt unusually fresh. Suddenly it occurred to me: Didn’t I go to eat? Why did you come to the courtyard!

So he immediately turned back and walked into the study again. When he saw the calculation manuscript spread out on the table, he forgot all about eating, and immediately went back to his desk to calculate nervously.

2. The story of Marie Curie

Marie Curie was a French-Polish scientist who studied radioactive phenomena and won the Nobel Prize twice in her life. Mary has been very diligent and hard-working since she was a child. She has a strong interest and special hobby in learning. She never misses any learning opportunity easily and shows a tenacious and enterprising spirit everywhere. Since elementary school, she has ranked first in every subject.

At the age of 15, he graduated from middle school with a gold medal for outstanding results. Her father had previously studied physics at St. Petersburg University. His thirst for scientific knowledge and strong ambition also deeply influenced little Mary. She loved the various instruments in her father's laboratory since she was a child. When she grew up, she read many books on natural science.

This made her full of fantasy, and she was eager to explore the world of science. But her family's financial situation did not allow her to go to college. At the age of 19, she began to work as a long-term tutor. At the same time, she also studied various subjects on her own to prepare for her future studies. In this way, until the age of 24, she finally came to study at the Faculty of Science of the University of Paris. She has a strong desire for knowledge.

Listening to every class with concentration, hard study made her physically worse and worse, but her academic performance has always been among the best, which not only made her classmates envious, but also surprised the professors. Two years after enrolling, she took the physics bachelor's degree exam with confidence and ranked first among 30 candidates. The next year, she obtained a bachelor's degree in mathematics with second place honors.

3. The Story of Franklin

One day in June 1752, in the suburbs of Philadelphia, USA, with dark clouds, lightning and thunder, there were two people, an old man and a young man, on a wide lawn. He was flying a kite there happily. Suddenly, a bolt of lightning split the clouds and made a "zigzag" in the sky, followed by a sound of thunder and raindrops pouring down. I saw the old man shouting loudly: "William, stand in the thatched house over there and tighten the kite string."

At this time, lightning flashed one after another, and the thunder was louder than the other. Suddenly William shouted: "Dad, look!" The old man looked in the direction his son pointed, and saw the tightened hemp rope, which was originally smooth. Suddenly, he became furious, and the thin fibers stood upright one by one. Get up. He shouted happily: "The lightning is coming!" He told his son to be careful.

While slowly approaching the copper key connected to the hemp rope with his hand. Suddenly he fell to the ground as if he had been pushed by someone, his whole body numb. Ignoring the pain, he climbed up from the ground and connected the Leyden bottle he brought with him to the copper key. Sure enough, there was electricity in this Leyden bottle, and it also released sparks. It turns out that electricity from the sky and electricity from the earth are the same!

He and his son took the Leyden bottle home as if they had found a treasure. The people who captured Tiandian were Franklin and his son William. Franklin was not only a great scientist, but also an outstanding statesman and diplomat. He was one of the initiators of the Declaration of Independence and the first ambassador of the United States to a foreign country.

After the kite experiment, Franklin wrote a paper "On the Identity of Lightning and Electricity", which explained the nature of lightning and proposed the idea of ??manufacturing lightning rods to protect buildings from lightning strikes.

The lightning rod invented by Franklin suddenly became popular and spread to Britain, France, Germany, Europe and America.

4. Nobel’s story

Nobel’s father was a talented inventor who was devoted to chemical research, especially the study of explosives. Influenced by his father, Nobel showed a tenacious and brave character since he was a child. He often went to experiment with explosives with his father. After many years of studying explosives with his father, his interest soon turned to applied chemistry.

In the summer of 1862, he began research on nitroglycerin. This is an arduous journey full of danger and sacrifice. Death was always with him. An explosion occurred during an explosives experiment. The laboratory was blown up without a trace, and all five assistants died. Even his youngest brother was not spared. This amazing explosion.

Nobel's father suffered a very heavy blow and died not long after. Out of fear, his neighbors also complained to the government about Nobel. After that, the government prohibited Nobel from conducting experiments in the city. But Nobel was unyielding and moved his laboratory to a boat in a lake on the outskirts of the city to continue his experiments. After long-term research, he finally discovered a substance that was very easy to cause explosions.

Mercury fulminate, he used mercury fulminate to make explosive detonators and successfully solved the problem of detonating explosives. This was the invention of the detonator. It is a major breakthrough on the path of Nobel science. Nobel made many inventions in his life, and obtained 255 patents, including 129 types of explosives alone. Even when he was dying, he still couldn't forget the research on new explosives.

5. Watt’s story

Watt was born in England. Due to his poor family, he had no chance to go to school. He first worked as an apprentice in a watch shop, and then worked as an instrument repairman at the University of Glasgow. Smart and eager to learn, he often took time to sit in on professors' lectures. In addition, he personally played with the instruments all day long, so he accumulated a lot of knowledge. In 1764, the University of Glasgow received a Newcomen steam engine that required repair.

The task was given to Watt. After Watt repaired it, he saw how hard he was working, like an old man panting and trembling while walking with a heavy load. He felt that it should be improved. He noticed that the main problem was that the cylinder heated up and then cooled down, and cooled down and heated up again with the steam, which wasted a lot of heat. Can it be kept cold and the piston still work as usual?

So he rented a cellar with his own money, collected several scrapped steam engines, and determined to build a new machine. From then on, Watt played with these machines all day long. Two years later, he finally came up with a new machine. But after trying to ignite it, the cylinder leaked air everywhere. Watt tried his best to wrap it with felt and oilcloth. Several months later, he still couldn't cure the problem.

Watt did not give up. After unremitting efforts, he finally designed a condenser that was separate from the cylinder. This tripled the thermal efficiency and used only a quarter of the original coal. Once this key point was broken through, Watt suddenly felt that his future was bright. He went to the university to ask Professor Black for some theoretical questions, and the professor introduced him to technician Wilkin who invented the boring machine.

The technician immediately used the method of boring the barrel to make the cylinder and piston, solving the most troublesome air leakage problem. In 1784, Watt's steam engine was equipped with a crankshaft and flywheel. The piston could be continuously pushed by steam coming in from both sides. There was no need for manpower to adjust the valve. The world's first real steam engine was born.

Einstein’s truant from school

In the spring of 1895, Einstein was 16 years old. According to German law at the time, boys who left Germany before the age of 17 did not have to return to serve in the military. Due to his deep hatred of militarism and the fact that he could no longer bear to be alone in the military-like Luipold High School, Einstein decided to leave Germany without consulting his parents and reunite with his parents in Italy. However, what should I do if I drop out of school and cannot get a diploma in the future? Einstein, who had always been honest and simple, came up with an idea that he thought was a good one in desperation. He asked his math teacher to give him a certificate saying that he had excellent math scores and had already reached the university level. He also got a sick leave certificate from a familiar doctor, saying that he had a nervous breakdown and needed to go home to rest. Einstein thought that with these two proofs, he could escape from this disgusting place. Unexpectedly, before he applied, the dean of students called him in and ordered him to drop out of school because he had ruined the class spirit and failed to abide by school discipline. Einstein blushed. No matter what the reason was, as long as he could leave this middle school, he was willing to do so and didn't care about anything else. He just suddenly felt guilty for having come up with a cunning idea that he never implemented. Later, Einstein felt guilty every time he mentioned it. Perhaps this kind of thing is too far away from his frank and sincere personality.

Qian Xuesen

A missile launch test was about to begin, but at that time The weather was very bad. The commander, chief of staff and Qian Xuesen of the test base had different opinions on whether it could be launched or not.

According to the regulations at the time, each launch report must be signed by three people in agreement, and then Marshal Nie Rongzhen was asked for approval. However, at that time, both the commander and the chief of staff said it could not be launched, but Qian Xuesen was very confident that it could be launched. This created a 2:1 situation, so the report signed by only Qian Xuesen was given to Nie Shuai. Unexpectedly, Nie Shuai readily approved the launch and said that if there were only those two signatures and no signature from Dean Qian, I would not dare to approve it. Do you think this missile was successfully launched? The result was that this missile was really successful.

Pauli

Once, when the Italian physicist Segre, who later discovered the antiproton, finished a report and Pauli and others left the conference room, Pauli said to him: " I've never heard a report as bad as yours." Segre said nothing at the time. Pauli thought for a while, then turned back to Brescher, a Swiss physical chemist who was traveling with them, and said: "If you were the one giving the report, the situation would be even worse. Of course, except for your last opening report in Zurich. . ”

Fisher

In Germany, many people like to attend concerts or watch operas, and Fisher is also a fan. After work, whenever there is a performance in the concert hall or opera house, he is a must-see. One day, there happened to be an opera performance in the city. After the experiment, Fisher packed up the laboratory and set off for the opera house. As soon as he entered the opera house, he noticed that some people were far away from him. He didn't mind and started to find his seat. As soon as he found the seat and sat down, the audience around him behaved strangely: at first they were whispering to each other, and then it seemed like someone was there. As if some order had been issued, everyone took out their handkerchiefs and covered their noses, turning around as if to avoid the plague. Some people wanted to escape from their seats. Finally someone couldn't stand it anymore and shouted loudly: "Where did the stench come from? Who put this groom who just came out of the stable into the theater!" At this time, Fisher woke up as if from a dream, and it turned out that he was the one who brought the scene to the audience. Suffering great inconvenience, he quickly stood up and left the theater quickly. After returning home, Fisher took a shower carefully and changed his clothes from the inside out, but the smell was still there, as if it was emanating from the skin. Fisher was a little frustrated. It seemed that the opera would not be available. But for the sake of scientific research, this sacrifice is nothing.

Marie Curie

Just as the Curies were gaining fame and conducting further research on radium, Mr. Curie unfortunately passed away in an accidental car accident. Marie Curie endured great grief and declined the official parade and speech in Paris for Mr. Curie. She only requested that Mr. Curie be buried in his mother's cemetery in his hometown with the simplest ceremony.

While teaching, Madame Curie continued to conduct in-depth research on radium. She also organized a radium research team to introduce radium, a mysterious element, to countries around the world. In December 1911, the Swedish Doctoral Academy of Science announced that she would be awarded this year's Nobel Prize in Chemistry. In the history of the Nobel Prize, only Marie Curie has won this prize twice. As usual, Marie Curie was going to Stockholm to give a public lecture. Accompanying her were her sister and her eldest daughter Kirina.

Nobel

Nobel is a real billionaire, with a cumulative fortune of 3 billion Swedish dollars. But he is very different from many wealthy people. He has always despised money and property. When his mother died, he donated all the inheritance her mother left him to charity, leaving only a photo of his mother as a permanent memorial. He said: "Money is enough as long as it can solve an individual's life. If there is too much, it will become a scourge that curbs talents. For those who have children, parents only need to leave them education expenses. If they provide more than education Excess property beyond expenses is wrong, it encourages laziness, and will prevent the next generation from developing their individual independent living abilities and intelligence.

”
