A. 50-word short stories invented by scientists

Edison, 1

When Edison was young, he often went to play in the mill of his neighbor Muir Winchester's house. One day, in Winchester's mill, he saw Winchester doing a flying device experiment with a balloon. This experiment fascinated Edison. He thinks that if a person's stomach is full of qi, he will surely ascend to heaven.

A few days later, Edison mixed several chemical raw materials and gave them to his father's assistant, Michael Oates. Edison told Michael Oates that people would fly after eating this kind of food, and Oates almost fainted after eating Edison's "flying agent".

Edison was whipped by his father, and his parents were vigilant, advising their children not to play with Edison and stay away from him.

2. Fulton

Fulton studied very little since he was a child, and his parents had no money for his education. His later achievements depend entirely on his personal struggle. Little Fulton loved fantasy since he was a child. For example, when he helps adults finish farm work, he often sits alone in the farmhouse attic, looking into the ground through a small window with wooden strips, looking at the blue sky and meditating for hours.

One day, the weather was fine and the river was clear. Little Fulton and his neighbor's uncle sailed to the upper reaches of the river to find jobs. They began to leisurely support the pole upstream.

When little Fulton left his village, he was so happy that he couldn't help singing American country folk songs. The sound of the river is intertwined with the melodious and euphemistic singing of little Fulton, which is fascinating. In the morning, the sun rises higher and higher, and the sunlight shines on the water waves like broken silver on a green ribbon.

Suddenly, the current was fast and the boat was spinning in the river. Fulton and his neighbor's uncle swam desperately, their clothes were soaked with sweat, but the boat could only move with difficulty. Little fulton thought, the pole vault is too hard. If there is something that can make the ship walk automatically, how nice it would be!

His imaginary wings are flying in the river, and he seems to see an automatic boat in the river. His thoughts came back to reality. He said to his neighbor uncle, "Uncle, getting on the pole is difficult and slow. If only there were something that could make the boat walk automatically! "

My neighbor's uncle was holding the pole hard, and he couldn't help laughing at little Fulton's words. He wiped the sweat on his face with the back of his hand and said with a smile, "If there is anything that can make the boat walk automatically, what is it?"

"Yes, what is this?" Little fulton's face suddenly turned red. He propped up the pole hard, lowered his head and lost in thought again.

After that, "how to make the ship walk automatically?" This became the central question of little Fulton's meditation. When he grew up, he worked hard and finally became a famous scientist, building the first steam engine ship, the Claremont.

3. Watts

It is said that when Watt was a child, he once saw the boiling water on the stove boil, and the steam pushed the lid of the kettle away. Watt put the lid back on, but it was quickly pushed away again.

Watt kept taking the lid off, trying to find out why. Later, Watt realized that it was the power of steam that aroused his interest in steam and led to the invention of the steam engine.

4. Luban

Legend has it that Lu Ban invented the "hook" and "refusal" for the Chu navy. When the enemy is at a disadvantage, the "hook" can hook the enemy ship to prevent it from escaping. When the enemy is in an advantage, "refusing to stop" can resist the enemy ship and stop its pursuit. After Gou Jian refused, the Chu army was invincible, and Lu Ban was also worthy of being a military expert.

One day, Lu Ban boasted to Mozi, "I have a hook that I won't fight on the boat. Is your righteousness also rejected? " Mozi advocated peace, opposed war, encouraged people to respect and love each other, and put justice first.

He then replied, "I hook up with love and refuse with respect." You hook people, people will hook you; If you refuse others, others will refuse you. Isn't the rejection of' righteousness' better than that of' boat'? "Ruban was speechless.

Lu Ban took out his invention: a wooden magpie can fly for three days without landing. Mozi said, "This wooden magpie is not as good as the handlebars cut by an ordinary craftsman in an instant. As soon as the handlebar is mounted on the axle, the cart can carry fifty stones. "

And what's the practical use of your magpie? What carpenters do is good for people, but bad for people can only be called clumsiness. "Upon hearing this, Lu Ban knew Mozi's philosophy.

Lu Ban used to be a ladder to help Chu attack the Song Dynasty, and Mozi came to stop the invasion. In the Chu Palace, clothes were the city, bamboo pieces were the utensils, and Lu Ban was at war. Luban's siege equipment is exhausted, and Mozi's method of guarding the city still exists. Finally, Lu Ban was persuaded and the king of Chu gave up attacking the Song Dynasty.

5. Bell

Bell's father is a speech physiologist and an expert in correcting speech and teaching deaf people.

Bell's grandfather is a philanthropist, and he has always been very sympathetic to the deaf and dumb. He often gathers some disabled people and educates them kindly. So the deaf-mute people simply worship him as a savior.

When his grandfather died, his father inherited his inheritance. Besides educating the deaf, he also studied the methods of speaking and pronouncing, hoping to help these unfortunate people. Bell grew up in this environment, so he always expected to make achievements in this field in the future.

One day, my father said to Bell in a gentle tone, "My son, the most painful thing in the world is being blind, deaf and dumb." . They are human beings like us, but their eyes can't see, their ears can't hear and their mouths can't talk. Beautiful clothes and beautiful scenery are invisible to the blind;

Wonderful music, funny jokes, deaf people can't hear; We can laugh and laugh and say whatever we want, but they are deprived of this right. Come to think of it, we are so happy.

Therefore, in addition to thanking God, we should also try our best to help and comfort them and let them live a normal life as much as possible. Children, when you grow up, you must save these unfortunate people! "

Bell often hears such teachings, so he regards lifelong efforts for the happiness of the deaf as his greatest career.

Bell has a kind heart and a flexible mind. He has played a high degree of love and keen brain power since he was a child.

There is a water mill near his home, where a father and son live. Usually, some heavy work is done by young people. Later, young people were recruited as soldiers, leaving the old man to grind his face to make a living.

When there is little water, the waterwheel can't move, and the old man can't grind powder, so he has to starve. Bell saw it and felt sorry for him, so he invited some children to help.

When there is water shortage, it is really not easy to grind noodles. We must promote the development of stone mill together. At first, everyone thought it was fun, but they were willing to help. Later, when they were tired, they left one after another, leaving Bell alone and naturally unable to push.

When Bell got home, he sat in his father's study and thought hard: How can we push the stone mill easily? After a month of research, he came up with a good idea.

First, improve the grinding teeth to reduce friction, and then use the round shape of wheat grains to make them close to each other, so that the rotation of grinding teeth is much more flexible. In this way, he not only helped the miller a lot, but also the whole village followed suit. Everyone thinks that the improved stone mill is really convenient and easy to use.

As a result, Bell, who was only 15 years old, became an "invention prodigy" in the eyes of the whole village.

B. Ask ten scientists to invent short stories, 50 words is the best.

First of all, the copier

At first, Edison invented paraffin paper, which was only widely used as packaging material for food and candy. Later, he tried to carve the outline of the words on wax paper to form a wax lettering paper tray, put white paper under the paper tray, and then rolled it off the wax lettering paper with an ink roller. A wonderful thing happened, and clear handwriting appeared on the white paper.

Later, after many improvement experiments, Edison began to produce the copier he invented in 1976, and all of a sudden institutions, schools, institutions and organizations adopted this stencil mimeograph. Because Edison's copier is very popular all over the world, Edison deeply realized that he should invent things that people generally and deeply need.

Second, synchronous transmitter.

Early telegrams could only transmit one message at a time, but could not exchange signals at the same time. Because Edison himself was a telegraph technician, he began to improve the traditional telegraph and made a double telegraph. 1974, he developed a quadruple telegraph, which is also a synchronous telegraph. At that time, before the development of radio, synchronous transmitter was a major breakthrough.

Third, improve the telephone.

As we all know, the modern telephone was invented by Bell. In fact, the telephone can send and receive clearly, thanks to Edison's repeated experiments, which broke through the traditional pattern and made a toner transmitter, which improved the sensitivity, volume and receiving distance of the telephone in one fell swoop. Otherwise, you will often say hello when you call now! Hey! I can't hear you. I can't hear you clearly.

Fourth, the phonograph was born.

/kloc-one night in February, 877, the staff of Mengluoyuan Laboratory trembled slightly, not because of the cold, but because they heard the recording for the first time in human history: "Ma Xuan has a little sheep with white fur as snow. Wherever Ma Xuan goes, the lamb is always by her side. ...

This great invention needs no more introduction from the little jar teacher, and everyone can understand how wide its application is. France * * *, and therefore awarded the title of Sir Edison! Later, Edison made many improvements to the phonograph until the drum was changed to a bakelite turntable. This is not a year or two, but after decades of continuous improvement!

Five newtons

Newton was alone in the orchard at home. Because he walked and thought, he accidentally bumped into an apple tree in the garden. At this moment, an apple just hit Newton's head. Newton suddenly woke up from the problem and picked up the apple. At this time, he fell into another problem: why did the apple fall to the ground instead of floating in the sky? Finally, Newton put forward a universal law of the simplest phenomenon: gravity.

C. the story about scientists is less than 50 words.

Benjamin Franklin accidentally thought of inventing the lightning rod;

Franklin's most famous discovery was the unification of sky and earth electricity, which broke people's superstition about lightning. In the process of discharge experiment with Leiden bottle, Franklin could not help but think of lightning in the sky in the face of the flash and crack of electric spark. He realized that the spark in the Leiden bottle might be a small lightning. In order to test this idea, lightning in the sky must be brought to the ground. 1752 On a thunderstorm day in July, Franklin made a big kite with silk, put a tapering iron wire on the top of the kite, and connected the iron wire with the ground with silk thread. At the end of the silk thread is tied a copper key, which is in a Leyden bottle. Franklin put the kite in the sky, and a flash of lightning struck, only to see the hairs on the silk thread stand up and put his hand close to the copper key, which is an electric spark. The Temple of Heaven was finally caught. Franklin discovered all the phenomena that the Leiden bottle that stored the sky electricity could produce the earth electricity, which proved that the sky electricity and the earth electricity were the same. 1747, Franklin discovered the phenomenon that the tip is easier to discharge from the Leyden bottle experiment. After he discovered the unification of sky electricity and ground electricity, he immediately thought of using the principle of tip discharge to introduce powerful lightning in the sky into the ground to avoid buildings being struck by lightning. 1760, Franklin erected a lightning rod on a building in Philadelphia, and the effect was very remarkable.

Newton was killed by an apple and discovered the law of gravity.

D. 50 words of short stories by scientists

[Name] Albert Einstein (Jewish theoretical physicist)

1895 spring, Einstein 16 years old. According to the laws of Germany at that time, boys could leave Germany before 17 years old and did not have to come back for military service. Because he hated militarism and couldn't bear to stay in the barracks alone-just like Louis Polder Middle School, Einstein decided to leave Germany and go to Italy to reunite with his parents without consulting his parents. However, what if I drop out of school and can't get my diploma later? Einstein, who has always been honest and simple, came up with a self-righteous idea in a hurry. He asked the math teacher to give him a certificate to prove that his math scores were excellent and he reached the university level early. I got a sick note from a familiar doctor, saying that it was neurasthenia and I needed to go home and rest. Einstein thought that with these two proofs, he could escape from this disgusting place.

Who knows, before he applied, the dean called him and ordered him to drop out of school on the grounds that he corrupted the class spirit and disobeyed the school discipline.

Einstein blushed. For whatever reason, he was willing to leave this middle school and didn't care about anything. He just suddenly felt guilty that he had come up with a cunning idea but it didn't come true. Einstein felt guilty every time he mentioned it later. Perhaps this kind of thing is far from his frank and sincere personality.

Newton was alone in the orchard at home. Because he walked and thought, he accidentally bumped into an apple tree in the garden. At this moment, an apple just hit Newton's head.

In addition to his inventions and contributions in phonograph, electric light, telephone, telegraph and film, Edison also had many famous creations and opinions in mining, architecture and chemical industry. Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization.

F. Scientists' short stories (less than 50 words)

Stephen william hawking, a graduate of Oxford University and Trinity College, Cambridge University, received his Ph.D. from Cambridge University, but he soon 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 could do nothing about the disease, but then the rate of disease 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. It is because of his physical disability and strong will! He has made outstanding achievements in cosmology and quantum physics! Known as the greatest physicist after Einstein!

G. stories about characters, about 50 words.

Lin Zexu was a patriotic politician, thinker and poet in Qing Dynasty. Historians call him "the first person who opened his eyes to see the world" in modern China. During the Opium War, he advocated the prohibition of opium, resisted the aggression of western capitalism, persisted in safeguarding China's sovereignty and national interests, seized and burned a large amount of opium, crushed many armed provocations by the British invaders, and showed great patriotism. Even the British businessman, the number one opium dealer, had to admit in front of such a clean imperial envoy: "His hands have never been stained by bribes. This situation is unheard of among China politicians. "

In 40 years, Lin Zexu traveled all over 14 province with 400,000 troops. In the end, he was penniless and penniless, just as he said in the book "Analysis of Family Property Self-determination" in his later years: "The discount of agricultural land property is zero" and "There is no cash at present!" It's admirable, admirable! All this, as the motto of the calligraphy hanging in the hall of his former residence shows: "All rivers run into the sea, with great tolerance;" The wall stands thousands of miles, and there is no desire. "

H. the stories of three world famous scientists. (About 50 words. )

Stories of famous scientists (1)

Archimedes (287-2 12 BC) was born in a small village near Syracuse, Greece. He was born into a noble family, and was related to King Hilong of Syracuse, and his family was very rich. Archimedes's father was an astronomer and mathematician, knowledgeable and humble. Influenced by his family, Archimedes became interested in mathematics, astronomy, especially ancient Greek geometry. When he was just eleven years old, with the help of his relationship with the royal family, he was sent to study in Alexandria, Egypt. Alexandria, located at the mouth of the Nile, was one of the centers of cultural trade at that time. There are magnificent museums, libraries and talented people here, which are praised as "the capital of wisdom" by the world. Archimedes studied and lived here for many years and had close contacts with many scholars. He absorbed the excellent cultural heritage of the East and ancient Greece and made great contributions to his later scientific career. In 2 12 BC, Roman troops invaded Syracuse, and Archimedes was killed by Roman soldiers at the age of 75. Archimedes' body is buried in Sicily, and the tombstone is engraved with a figure of a cylinder engraved with a ball to commemorate his outstanding contribution to geometry.

Archimedes' achievements

Archimedes is undoubtedly the greatest mathematician and scientist produced by ancient Greek civilization. His outstanding contributions in many scientific fields earned him the high respect of his contemporaries.

Archimedes worked out the areas and volumes of parabolic bows, spirals and circles, as well as the volumes of complex geometric bodies such as ellipsoids and paraboloids. In the process of deriving these formulas, he skillfully used the "exhaustive method", which is what we call the method of gradually approaching the limit today, so he is recognized as the originator of calculus calculation. In this way, he also estimated that the value of ∏ was between and got the solution of cubic equation. Facing the tedious numerical representation in ancient Greece, Archimedes put forward an important method for calculating grades and used it to solve many mathematical problems. Archimedes made the most outstanding achievements in mechanics, mainly focusing on statics and hydrostatics. In the process of studying machinery, he discovered the lever principle and used this principle to design and manufacture many machines. He discovered the law of buoyancy in the process of studying floating bodies, which is also known as Archimedes principle.

Archimedes is not only a theorist, but also a practitioner. Throughout his life, he was keen on applying his scientific discoveries to practice, thus combining the two. In Egypt around 1500 BC, people used levers to lift heavy objects, but people didn't know why. Archimedes devoted himself to this phenomenon and discovered the lever principle.

King Hennon always doubted Archimedes' theory. He asked Archimedes to turn them into living examples to convince people. Archimedes said, "Give me a fulcrum and I can move the earth." The king said, "I'm afraid this can't be realized." You'd better help me tow that big boat on the coast. " This ship was built by King Henon for the king of Egypt. It is very large in size.

I. The story of a scientist in 50 words

After Rutherford confirmed the existence of nucleus from the small scattering experiment of α particles, many scientists found that the mass number of nucleus did not match the proton number. On the basis of experiments, Rutherford actively thought, and finally successfully predicted the existence of neutrons, which greatly promoted the development of atomic physics.

In addition to his inventions and contributions in phonograph, electric light, telephone, telegraph and film, Edison also had many famous creations and opinions in mining, architecture and chemical industry. Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization.

When Franklin was seven years old, there was a festival where adults gave him a lot of money. Franklin is going to use this huge sum to buy some toys in the shop. On the way, he saw a boy whistling proudly. He was completely fascinated by the whistle and exchanged all his money for the boy's whistle. Back home, Franklin proudly blew his whistle around the house, but it disturbed the whole family. After his family knew about his transaction, they told him that he paid four times more than the original price for this whistle, and let him know that the extra money could buy more and better things.

Deng Jiaxian

Once, a parachute accident occurred during the flight test, and the atomic bomb fell to the ground and cracked. Deng Jiaxian knew the danger well, but he grabbed it by himself and took the broken atomic bomb fragments in his hand for careful inspection. As a medical professor, his wife knew that he had the cracked atomic bomb and forced Deng Jiaxian to return to Beijing for inspection. It was found that there were radioactive substances in his urine, liver damage and radioactive substances in his bone marrow. Subsequently, Deng Jiaxian still insisted on returning to the nuclear issue.

Test base. When struggling, he insisted on installing the detonator himself, and for the first time, he gave an order to the people around him with the authority of the dean: "You are too young to leave!" 1985, Deng Jiaxian finally left lop Nur and returned to Beijing, still wanting to attend the meeting. The doctor forced him to be hospitalized and told him that he had cancer. He collapsed feebly in his hospital bed, facing the comfort of his wife and defense minister Zhang Aiping, and said calmly, "I knew this day would come, but I didn't expect it to come so soon."

Samuel Chao Chung Ting

1In the summer of 972, the Ding Zhaozhong experimental team used the proton accelerator of Brookhaven National Laboratory in the United States to find long-lived hitting particles with the mass between1.5×109 ev and 5.5×109 ev. 1974, they discovered a long-lived hitting particle (energy is 3. 1× 109eV) whose mass is about three times that of protons. When publishing this discovery publicly, Ding Zhaozhong named this new particle J, in which "J" is similar to the Chinese character "D", indicating that it was discovered by China people. At the same time, American Richter discovered this kind of particle and named it ψ particle. Later, people called this particle J/ψ particle. J/ψ particles have peculiar properties, and their life span is 5000 times longer than expected. This shows that it has a new internal structure, which can't be explained by three kinds of taste quarks known at that time, and it needs to be explained by introducing a fourth kind of quark-charm quark. The discovery of J/ψ particles greatly promoted the development of particle physics.
