The story of invention and discovery is 50 words.
Pasteur has made great contributions to the disease prevention and control of human beings and livestock and poultry raised by human beings. Due to outstanding achievements in science. He enjoys a high reputation throughout Europe, and the University of Bonn in Germany solemnly awarded this scholar an honorary degree certificate. However, after the Franco-Prussian War broke out, Germany occupied French territory. Out of deep affection for the motherland and deep hatred for the aggressor Germany, Pasteur resolutely returned the honorary degree certificate to Bonn University.
Robert Boyle continued his experiments with glass pistons and found many noteworthy things. When he exerts double pressure on the blocked air, the volume of the air will be halved; When the pressure is tripled, the volume will become the original 1/3. When squeezed, the change of air volume is always proportional to the change of pressure. He created a simple mathematical equation to express this proportional relationship, which we now call Boyle's law.
Priestley is studious and has a wide range of interests. He has studied classical Chinese and mathematics. Introduction to natural philosophy, etc. He interrupted his study for a period of time because of his poor health. After his recovery, he entered a non-state college in Coventry. Because of his hard work and excellent grades, the school agreed to exempt him from some courses in the first and second grades. In the later study, he deeply felt that his foundation in mathematics and German was too poor, and asked the school to allow him to make up these two courses.
The story of the invention of electronic frog eyes, about 50 words.
Scientists have done many experiments with the eyes of green frogs.
According to the frog's eyes, scientists invented the "electronic frog's eyes". Because frogs have strange eyes, they are keen to see moving things, but they "turn a blind eye" to static things. Scientists got inspiration from frog's eyes and invented "electronic frog's eyes". This kind of "electronic frog eye" can accurately identify objects with specific shapes like real frog eyes. After installing electronic frog in radar system, the anti-jamming ability of radar is greatly improved. This radar system can quickly and accurately identify aircraft, ships and missiles with specific shapes. In particular, it can distinguish between true and false missiles and prevent false confusion.
Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and give an alarm in time if it is found that the aircraft is about to collide. On the main road, you can direct the vehicles to prevent them from colliding.
From this, I think there are many things in nature that we need to learn. As long as you observe carefully and think carefully, you can get greater gains.
50 words about the story of invention and creation
Luban went up the mountain to cut firewood and accidentally slipped down the mountain. When he slipped down, he caught a grass, but he felt a sharp pain, so he let go of his hand and went home to see his hand dripping blood.
The next day, he went up the mountain and found that the grass was serrated, so he invented the saw.
Inventor's story in 50 words.
Edison
The world-famous American electrician and inventor is known as the "king of inventions in the world". In addition to his inventions and contributions in phonograph answering, electric light, telephone, telegraph and film, he also has 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.
Edison was also a great entrepreneur. 1879, Edison founded "Edison Electric Lighting Company". 1880, incandescent lamps went on sale. 1890, Edison established Edison General Electric Company in all its businesses. 189 1 year, Edison's thin filament and high vacuum incandescent bulb were patented. 1892, Tom? Houston Company merged with Edison Electric Lighting Company to form General Electric Company. Opened the dominance of general electric in the electrical field for a century.

Madame Curie's childhood story
A few decades ago, there was a little girl named Manya in Poland. She was very absorbed in her study. No amount of noise around can distract her. Once, Manya was doing her homework, and her sister and classmates sang, danced and played games in front of her. Manya didn't seem to see it, so she was absorbed in reading.
My sister and classmates want to test her. They quietly set up some stools behind Manya, and whenever Manya moved, the stools would fall down. As time went by, Manya finished reading a book and the stool was still standing there.
Since then, my sister and classmates have never made fun of her, and like Manya, they concentrate on reading and study hard.
Manya became a great scientist when she grew up. She is Madame Curie.
Ask ten scientists to invent short stories, and 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 need universally and deeply.
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.
Stories of scientific inventions and discoveries (20-50 words)
1. Discovery of buoyancy
Archimedes found the story of buoyancy in the bathtub.
2. The invention of the telephone
1June 2, 875, Bell and his assistant Watson tested multiple telegrams in two rooms respectively. In Watson's room, there is a spring stuck to the magnet of the telegraph. When Watson pulls open the spring, it vibrates and makes a sound. Bell and Watson made the telephone according to this new idea.
3. Seismograph
However, Zhang Heng does not believe in supernatural evil. After careful investigation and experiment of recorded earthquake phenomena, he invented an instrument that can detect earthquakes, called "seismograph". The faucet extends in eight directions. Every dragon has a small copper ball in its mouth. There is a toad with a big mouth under the tap. When there is an earthquake in any direction, the dragon mouth in that direction will automatically open and spit out copper balls.
4. Invention of lightning rod
1752, 46-year-old American scientist Franklin made a kite out of silk and put it into the sky with a string in a stormy weather. The metal key is tied to the lower end of the rope. When the string is wet by rain, it becomes a conductor. Franklin believed that if a metal conductor was installed in a tall building and the lower end of the conductor was grounded, according to the principle of tip discharge, the danger of lightning strike on the building could be avoided. This led to the invention of lightning rod.
5, the invention of the helicopter
1907, the world's first helicopter similar to "Qingyan" was successfully developed by French engineers Borregg and Richter. The plane has no wings, and the first arm has two four-leaf propellers, which can rotate horizontally.

It's raining. I'm walking in the rain in my raincoat. I can't help but get lost in thought: when it rains, it is convenient for people to sit on bicycles or motorcycles and wear raincoats, but the fly in the ointment is their feet, because every time it rains, their shoes will always get wet, and you will definitely say, "Don't wear rain boots?" Indeed, it is ok to wear rain boots when going out at ordinary times. However, if you meet a grand event, it will be unsightly to wear rain boots, not to mention that the road is too slippery on rainy days, and it is easy to slip on the ground if you are not careful.
At first, I imagined making the rain pants long enough to cover the shoes, so that the rain wouldn't hit the shoes, but sometimes the rain would rise, so wouldn't it still wet the shoes? Later, I designed a shoe cover with a tarpaulin, put it on my feet, and then connected the rain pants with a zipper. I think this is the best design. Who knows, when I cured him, I walked in the rain for a while. Not only was it not as good as expected, but the shoe cover also wore a big hole, and I was disappointed at once. The original self-confidence was exchanged for the disappointment now. I don't think I can expect to finish this pair of rain pants anymore.
A few days later, I saw several children playing football, which reminded me of my failed work, but I had a brainwave: why can football be played on the ground for a long time without breaking? I walked over and touched the football, and suddenly it dawned on me that the football wouldn't wear too much because it was wrapped in a thick leather bag. ... expand all >
Scientists invented a 50-word short story.
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 asked 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.
A brief summary of stories about inventions and discoveries.
On one occasion, the king ordered Luban to cut down 300 beams and columns in fifteen days to build a big palace. So, Lu Ban took his disciples up the mountain. They got up early and were greedy for the dark, wielding axes and chopping for ten days in a row. They were exhausted one by one, and only one hundred big trees were cut down.
At this time, all the bricks and stones are ready, and the auspicious day chosen by the king is about to expire. If the wood is not properly prepared during construction, it will be put to death. What shall we do? At night, Ruban tossed and turned in bed and couldn't sleep. He got up and walked towards the mountain with a deep foot and a shallow foot. Looking up, the seven stars blinked at him, and it was almost dawn.
Suddenly, Luban felt that his hand was cut by something. When he raised his hand, he saw a hole in his calloused hand, oozing blood beads. He looked around carefully, and it turned out to be thatched grass. Ruban was surprised. He picked up a blade of grass and found many sharp teeth on its edge. Turning around, he saw a big locust with two big ears eating grass quickly. Luban caught a locust, and when he saw it, its teeth grew well. Look at the leaves of silk grass and the big die of locust, and his heart will be suddenly enlightened. He made a bamboo out of Phyllostachys pubescens, which was carved with many serrations like silk grass leaves and locusts. Pull the tree with it, only a few times, the bark will be broken, and once again, there will be a deep ditch on the trunk. But after a long time, the sawtooth on the bamboo piece is either pure or broken. At this time, Lu Ban thought of iron. He ran down the mountain and asked the blacksmith to make a serrated iron bar based on the bamboo pieces he made, which was used to pull the tree. Really fast!
This iron bar is the prototype of a saw. With it, Luban and his disciples cut down 300 beams and columns in 13 days.
