A Yuan Longping-Keep everyone away from hunger.

Yuan Longping is an academician of China Academy of Engineering, a famous hybrid rice expert, the winner of the highest national science and technology award and the first national special invention award in China. Won the grand prize 1 1 times in the world. The "World Food Award" won is the highest international honor in the agricultural field.

He is a real cultivator. When he was a rural teacher, he had the courage to subvert the world authority; When he was famous all over the world, he still only focused on the land, indifferent to fame and fortune, a farmer, spreading wisdom and harvesting wealth. His lifelong dream is to keep all people away from hunger. I like watching thousands of waves of rice, especially the romantic Yuan Longping.

Uh Edison

Edison was a poor worker before he became famous. Once, his old friend met him in the street and said with concern, "look, this coat on you is very worn." You should get a new one. " "Need it to be? Nobody knows me in new york. " Edison answered indifferently. A few years later, Edison became a great inventor. One day, Edison met that friend again in the street of new york. "Oh," exclaimed my friend, "why are you still wearing this old coat? This time, I have to change a new one anyway! " "Need it to be? Everyone here already knows me. " Edison still answered casually.

The story of scientific discovery

Pasteur (Louis) was born in Dole, Jura, France on February 27th, 1822. His father is a veteran of Napoleon's army and a tanner. 1847, Pasteur graduated from Paris Teachers College. After graduation, I engaged in chemical research and studied tartrate crystals. He found that these crystals are not exactly the same, they have hidden asymmetry, and some crystals are mirror images of other crystals, just like the relationship between left hand and right hand. His achievements in crystal research played a decisive role in the development of stereochemistry. Later, it was found that Pasteur was very lucky when he took the method of preparing crystals. In order to get the separated two crystals, he had to use a special method, but Pasteur adopted this special method completely by accident, and few people after him could make large asymmetric crystals like him. As Pasteur said, "Opportunity favors those who are prepared".

Pasteur became famous at a stroke. He won many professorships and became a member of the Honorary Corps. Although he became famous in chemistry, what made him shine in history was his great achievements in microbiology.

1In September, 854, the French Ministry of Education appointed Pasteur as the president of Lille Institute of Technology and the head of the Department of Chemistry. There, he became interested in the alcohol industry, and an important process of making alcohol is fermentation. At that time, an alcohol factory in Lille encountered technical problems and asked Pasteur to help study the fermentation process. Pasteur went deep into the factory and brought all kinds of beet root juice and fermentation broth back to the laboratory for observation. After many experiments, he found that there was a sphere much smaller than yeast in the fermentation broth, which grew up to be yeast.

After a period of time, the buds grow on the phyllodes, and when they grow up, they fall off and become new spheres. In this continuous cycle, the beet root juice is "fermented". Pasteur continued his research and found that alcohol and carbon dioxide gas produced during fermentation came from the decomposition of sugar by yeast. This process can even occur in the absence of oxygen. He believes that fermentation is the anaerobic respiration of yeast and controls its living conditions, which is the key link in wine making.

Pasteur clarified the mystery of fermentation, and from then on Pasteur finally became a great microbiologist and the founder of microbiology.

At that time, the French beer industry was very famous in Europe, but beer often turned sour. The whole barrel of delicious beer turned into sour mucus and had to be dumped, which made the wine merchants complain bitterly and some even went bankrupt. 1865, the owner of a brewery in Lille asked Pasteur to help cure the disease of beer and see if a chemical could be added to prevent beer from turning sour.

Pasteur promised to study the problem. He observed under a microscope and found a spherical yeast cell in the liquid of aged wine and beer. When wine and beer turn sour, there will be lactobacillus in wine. It is this "bad guy" who breeds in nutritious beer and makes the beer "sick". He put the closed wine bottle in a wire basket, soaked it in water and heated it to different temperatures, trying to kill lactic acid bacteria without boiling beer. After repeated experiments, he finally found a simple and effective method: as long as the wine is kept at 50℃ or 60℃ for half an hour, the lactic acid bacteria in the wine can be killed. This is the famous "pasteurization method", which has been used to this day and is also the sterilized milk on the market.

At that time, the owner of the brewery didn't believe in Pasteur's method. Pasteur was in no hurry. He heated some samples, others didn't, and told the host to wait patiently for several months. As a result, the heated sample tastes pure after opening, while the unheated sample is very sour.

When Pasteur became a legend in France, sericulture in southern France was facing a crisis. A disease caused the death of a large number of silkworms, which severely hit the mixed silk industry in the south. People turned to Pasteur for help, and Pasteur's teacher, Duma, encouraged him to take up the burden.

"But I have never dealt with silkworms!" Pasteur said uncertainly.

"Isn't that better?" Teacher Duma encouraged him to say.

When Pasteur thought that France would lose 654.38 billion francs every year because of silkworm disease, he no longer hesitated. As a scientist, he has the responsibility to save the endangered French sericulture. Pasteur accepted the appointment of the Minister of Agriculture and went to Alai, a sericulture disaster area in southern France, on 1865.

Silkworm suffers from a mysterious and strange disease, which makes people feel very uncomfortable. Sick silkworms often hold their heads high and stretch their feet like cat claws to catch people. Silkworms are covered with brown and black spots, as if covered with pepper. Most people call this disease "pepper disease". Some sick silkworms died soon after hatching, and some struggled to survive to the third or fourth age, and finally died. Few silkworms cocoon, but the silkworms that can be drilled out are incomplete, and the offspring are also sick silkworms. The local sericulture people have tried everything, but they still can't cure the silkworm disease.

Pasteur observed with a microscope and found an oval brown particle that infected a silkworm and mulberry leaves that raised silkworm. Pasteur stressed that all infected silkworms and contaminated food must be destroyed and silkworms must be raised from scratch. In order to prove the infectivity of "pepper disease", he used this pathogenic granule to brush mulberry leaves, and healthy silkworms got sick immediately after eating it. He also pointed out that the pathogens of silkworms placed on the shelf can be transmitted to the silkworms in the lower shelf through the falling silkworm droppings.

Pasteur also discovered another disease of silkworm-intestinal disease. The bacteria that cause this silkworm disease parasitize in the intestines of silkworm, making the whole silkworm black and die. A corpse is as soft as an air bag and perishable.

Pasteur told people that the method of eliminating silkworm disease is simple. By checking and eliminating the diseased moth, the spread of the disease can be stopped, and silkworms can be hatched without the eggs of the diseased moth. This method saved sericulture in France.

Pasteur invented many things in his life and made outstanding contributions to biological science and medicine. By chance, he found a panacea for chickens.

Chicken cholera is a rapidly spreading plague, which is extremely fierce. Once the chickens raised at home are infected with chicken cholera, they will die in batches. Sometimes, people just saw some chickens foraging around. After a while, their legs suddenly trembled, then they fell down, struggled a few times and died. When some peasant women close the chicken coop at night, they are very happy to see all the chickens dead and lying in the coop. 1880, there was a terrible chicken cholera epidemic in rural France, and Pasteur was determined to win the plague.

In order to find out the cause of chicken cholera, Pasteur took the cultivation of pure chicken cholera bacteria as a breakthrough. He tried many cultural solutions. He concluded that the intestine of chicken is the most suitable breeding environment for chicken cholera bacteria, and the infectious medium is chicken feces. He tried many times, but all failed. In a daze, he had to relax, stop his research work and have a rest.

After a few days' rest, Pasteur began his research experiment again. At this time, they discovered the "New World". He inoculated the chicken with the old culture solution, but the chicken was not infected, as if the cholera bacteria had lost its effect on the chicken. What's going on here? Pasteur finally found that the toxicity of cholera bacteria gradually weakened due to the role of oxygen in the air. So, he injected healthy chickens with bacterial liquid for several days, 65,438+0 months, 2 months and 3 months, and made a set of comparative experiments. The mortality rates of chickens were 65,438 000%, 80%, 50% and 65,438 00% respectively. If the bacterial solution is injected for a longer time, the chicken will get sick, but it will not die. Things didn't end there. He also inoculated the same batch of chickens with fresh bacterial liquid. To his surprise, almost all the chickens inoculated with the old bacterial liquid were safe and sound, while those without the old bacterial liquid died completely. Practice has proved that all chickens injected with low toxic bacteria liquid, and then injected with virulent enough chicken cholera bacteria, are also drug-resistant, and their condition is mild or even has no effect.

The method to prevent chicken cholera has been found! Pasteur's accidental discovery made him confirm the principle of attenuated immunization, which led to the idea of making anthrax vaccine. Although he was a former British doctor and Jenner invented the method of vaccinia inoculation, Pasteur was the first person who consciously cultivated and made a successful immune vaccine and widely used it to prevent many diseases.

"Will, work and success are the three elements of life. Will will open the door to your career; Work is the way to enter the room; At the end of this road, there is a success to celebrate the results of your efforts ... As long as you have a strong will and work hard, you will have a successful day. " This is a famous saying of Pasteur about success.

One day, while drinking tea, he looked at the moving lid of the pot. He looked at the pot on the stove and the cup in his hand, and suddenly he was inspired: the tea is getting cold, so pour it into the cup; If the steam is cold, why not pour it out of the cylinder?

Taking this into account, Watt immediately designed a condenser separated from the cylinder, which increased the thermal efficiency by three times, while using only one quarter of the original coal. As soon as this key place broke through, Watt suddenly felt that the future was bright. He went to the university to ask Professor Black some theoretical questions, and the professor introduced him to Wilkin, the technician who invented the boring machine. Technicians immediately made the cylinder and piston by boring the barrel, which solved the most troublesome air leakage problem.

A fur trader likes fishing, and the place he often goes is Newfoundland fishing ground. One winter morning, the fur trader came to this fishing ground again. Maybe it's because it snowed heavily the night before. It was very cold that day, and the whistling wind blew on my face like a knife. The cobbler made great efforts to cut a hole in the frozen sea and then began to fish. He saw a very interesting phenomenon: the fish caught on the ice quickly froze hard, and as long as the ice did not melt, the fish would not taste bad after three to five days. Can food be frozen to keep fresh? The cobbler asked himself this question. He started the experiment. After many explorations, he found that not only fish can keep fresh under freezing conditions, but also other foods, such as beef and vegetables. He decided to make a refrigeration machine.

The story of a scientist (within 100 words)

One day, Zhang Heng read four poems from a collection of poems, describing the changes of the Big Dipper in the evening of each season: "bucket handle refers to the east, and the world is spring; Guide to barrel handle, it's summer in the world; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world. " He thinks it's interesting. The stars twinkle in the sky, some like dustpans, some like buckets, some like dogs, and some like bears. What are their operating rules? This is simply wonderful. So Zhang Heng drew a sky map according to the content of the poem and referring to other books. Every night, as long as there are no clouds, he silently observes the night sky in front of the star map. How many mysteries are there in the vast starry sky? He observes, records and thinks. His mind is full of all kinds of questions and colorful fantasies. Later, he finally confirmed that the descriptions in those four poems were not accurate enough. In fact, the barrel handle refers to the northeast in early spring and the southeast in late spring.

Qian Xuesen's story before returning to China

Author: Anonymous article Source: Excerpted from the number of clicks on the Internet: updated on May 2, 2007

When the first five-star red flag was slowly raised in Tiananmen Square in 1949, Qian Xuesen, then director of the supersonic laboratory of California Institute of Technology and head of the Guggenheim Jet Propulsion Research Center, was deeply happy for the rebirth of the motherland. He intends to return to China and use his professional knowledge to serve the new China. However, it was not easy for China scientists in the United States to return to China at that time, and Qian Xuesen's expertise was directly related to national defense, so he finally returned to the embrace of the motherland after going through hardships. His tortuous struggle process showed Qian Xuesen's love for the motherland at that time, which was very touching.

1in mid-September, 950, Qian Xuesen resigned as the director of the supersonic laboratory of California Institute of Technology and the head of the Guggenheim Jet Propulsion Research Center, and went through the formalities of returning to China. He bought a plane ticket from Canada to Hong Kong and gave his luggage to the handling company for consignment.

However, just two days before he planned to leave Los Angeles, he suddenly received a notice from the US Immigration and Naturalization Service that he was not allowed to return to China! The Immigration Bureau threatened to leave the country without authorization and be fined or even jailed if caught!

A few days later, Qian Xuesen was arrested in the detention center of the US Immigration and Naturalization Service. The "crime" is "participating in a political party that advocates overthrowing the United States by force."

The luggage handed over by Qian Xuesen to the handling company was inspected by the US Customs and the Federal Bureau of Investigation. It is said that telegraph codes, weapons drawings and the like are all "found" from it. The Immigration and Naturalization Bureau wants to "interrogate" Qian Xuesen, saying that Qian Xuesen is "an American". Later, it was said that among several American classmates that Qian Xuesen knew when he was studying in the United States, several were members of the United States. The Bureau of Immigration and Naturalization threatened Qian Xuesen to "violate American immigration laws" and "expel Qian Xuesen". It didn't take long for him to change his mind. Because Qian Xuesen is going to be "deported", which is exactly what Qian Xuesen wants! In the detention center, Qian Xuesen was imprisoned like a criminal. Qian Xuesen once recalled: "15 days of confinement, I lost 30 pounds." In the detention center, every night, spies will come in every hour to wake you up, so that you can't rest and are in an extremely nervous state. "

The persecution of Qian Xuesen by the Immigration and Naturalization Service aroused public indignation in the American scientific community. Many American friendly people came forward to rescue Qian Xuesen and find a defense lawyer for him. They raised $ 15000 as a deposit to bail Qian Xuesen out of the detention center.

1June, 955, Qian Xuesen wrote to Comrade Chen Shutong, then vice chairman of the National People's Congress Standing Committee (NPCSC), asking the Party and * * * to help him return to the embrace of the motherland at an early date. Premier Zhou attached great importance to this matter and instructed relevant personnel to deal with it at an appropriate time. After hard work, in June 195565438+ 10/8, Qian Xuesen's family finally returned to the motherland after 20 years' absence. Soon, he was appointed as the director of the Institute of Mechanics, Chinese Academy of Sciences.

Newton was alone in the orchard at home. Because he was thinking while cooking food, 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.

Hunting with eagles

Hawking, a scientist, seems to have a weak learning ability when he was a child. He learned to read the edition very late. After school, he never achieved the top 65,438+00 in the class power level. Moreover, because his homework is always "untidy", his teachers think he is "hopeless" and his classmates regard him as the object of ridicule. When Hawking 12 years old, two boys in the class took a bag of candy and bet that he would never succeed. The classmates ironically nicknamed him "Einstein". Who knows, after more than 20 years, the little boy who was not outstanding in those days really became a master of physics. What is the reason?

As it turns out, with the growth of age, Hawking became interested in how everything works. He often takes things apart to get to the bottom of them, but when he reassembles them, there is nothing he can do. However, his parents didn't punish him for it, and his father even gave him a "coach" in math and physics. At the age of thirteen or fourteen, Hawking found himself very interested in the study of physics. Although middle school physics is too easy and simple, it is particularly boring, but he thinks it is the most basic science, which is expected to solve the problem of where people come from and why they are here. Since then, Hawking has started a real scientific exploration.

From 1685 to 1687, with the encouragement and sponsorship of astronomer Harley, Newton published the famous mathematical principles of natural philosophy, completed the historical discovery-the laws of motion and gravity, and made great contributions to the development of modern natural science. In 2003, he was elected president of the Royal Society. 36860 . 68686868686

Newton, 12 years old, showed interest in experiments and mechanical inventions when he was studying in public schools in Grantham, and made water clocks, windmills and sundials by himself. In 2008+06 1 year, Newton studied at Trinity College of Cambridge University and became an excellent student. In 2008+0669,

Newton not only made great contributions in mechanics, but also made great contributions in other aspects. In mathematics, he discovered binomial theorem and founded calculus. In optics, the dispersion experiment of solar light was carried out, which proved that white light is composed of monochromatic light, studied the theory of color, and invented the reflecting telescope.

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

Waiting in a long line, my mind was still full of research, and I didn't respond when I called my name. It happened that an acquaintance next to him told him, "isn't your name Thomas?" Edison? " But he said, "Where have I heard this name?" Oh! By the way, isn't that my name? "

Edison was often in danger because he was interested in many things. Once, he went to the house where wheat was stored and accidentally bumped into the wheat barn. Wheat can't move with his head buried. He almost died, but fortunately he was found in time, grabbed Edison's foot and pulled him out.

At first, Edison invented paraffin paper for packaging. Later, he tried to carve words on it, put white paper under the paper tray, and then rolled it up from paraffin paper with an ink roller. Clear handwriting appeared on the white paper. Later, after many improvement experiments, Edison began to mass-produce the copier he invented in 1876. Suddenly, the group adopted this template mimeograph.

Once, when he wanted to replace an old painting on the wall, he moved a ladder to climb it. Suddenly, I fell off the ladder. After falling to the ground, he ignored the pain and immediately thought: Why do people fall straight? It seems that objects always move along the path of least resistance. Einstein walked slowly to the table and wrote down his thoughts. This is a great inspiration for his study of relativity.

Galileo thought he needed to make a more convincing demonstration in front of the public to make people accept his findings. It is said that in order to demonstrate this new discovery, he stood on the top of the famous leaning tower of Pisa and dropped a 19 1 0 pound shot from the height of1foot. Although it is not certain whether he threw the shot put on the tower, the law of free fall finally came true.

Yukawa Hideki likes to meditate and is not sociable, but he dares to explore and put forward original ideas in his mind. His prediction, like Dirac's positron prediction, shows the pseudo-great power of the theory. Yukawa theory promoted the development of meson physics. His achievements promoted the development of Japanese physics. . The institute he led has become the center of new disciplines such as biophysics and cosmology.

) started his first experiment in his own wooden shed.

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

(2) Try to do more with less time.

"Waste, the biggest waste is wasting time." Edison often said to his assistant. "Life is short, so we should try to do more with less time."

One day, Edison was working in the laboratory. He handed his assistant a pear-shaped empty glass bulb without a lampholder and said, "Measure the capacity of the bulb." He bowed his head to work again.

After a long time, he asked, "What's the capacity?" He didn't hear the answer, turned to see the assistant measuring the circumference and inclination of the light bulb with a soft ruler, and poured the measured figures on the table for calculation. Because the light bulb is pear-shaped, not a regular shape. Therefore, it is very difficult to calculate the circumference and inclination of the light bulb. He said, "Time, time, why does it take so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "Pour the water into the measuring cup and tell me its capacity at once."

The assistant read out the numbers at once.

Edison said, "How easy it is to measure. It is both accurate and time-saving. Why didn't you think of that? " ? Still counting. Isn't that a waste of time? "

The assistant's face turned red.

Edison murmured, "Life is too short, too short. Save time and do more! " "

(3) Even sleeping is absorbing the nutrition in the book.

In order to do experiments, Edison often stayed outside the laboratory and stayed awake for several days. I was so tired that I took a nap with a book as a pillow on the experimental table. One day, his friend made fun of him and said, "No wonder Edison knew so many inventions. It turned out that he was absorbing the nutrition in the book even when he slept. "

(4) Why can hens hatch chicks and I can't?

Once, when it was time for dinner, Edison still didn't come back. My parents are worried and look around. It was not until the evening that I found him in the hut next to the yard. Seeing him lying motionless in the haystack with many eggs, his father asked very strangely, "What are you doing?" Little Edison replied unhurriedly, "I'm incubating chickens!" " "It turned out that he was surprised to see that hens could hatch chicks, and he always wanted to try it himself. At that time, his father pulled him up with anger and laughter and told others not to hatch chickens. On the way home, he asked doubtfully, "Why can hens hatch chicks and I can't?"? "

(5) What's the secret in the wild beehive?

Edison was often in danger because he was interested in many things. Once, he went to the house where wheat was stored and accidentally bumped into the wheat barn. Wheat can't move with his head buried. He almost died, but fortunately he was found in time, grabbed Edison's foot and pulled him out. Another time, he fell into the water and was pulled up like a drowned rat. He's scared himself. When he was 4 years old, he wanted to see what was in the wild beehive on the fence, so he stabbed it with a branch, and his face was so red and swollen that he could hardly open his eyes. The best thing is that he saved his mother with a mirror. At night, he created the sun for her. If you put the mirror behind the candle, there will be an extra lamp.

The story about Einstein

(Story 1) Einstein was a playful child when he was a child. His mother often worries about this, and her repeated warnings go in one ear and out the other. Until the autumn of 16, one morning, my father stopped Einstein who was about to go fishing by the river and told him a story that changed Einstein's life.

The story goes like this:

"Yesterday," Einstein's father said, "Uncle Jack and I, our neighbors, cleaned a big chimney in the southern factory. The chimney can only go up if you step on the steel ladder inside. Your uncle Jack is in the front and I am in the back. We grabbed the handrail and finally climbed up step by step. When I came down, your uncle Jack was still in front and I was still behind him. Later, when I came out of the chimney, I found a strange thing: your uncle Jack's back and face were blackened by soot in the chimney, but I didn't even have any soot on me. "

Einstein's father continued to smile and said, "I saw your uncle Jack and thought I must be dirty like a clown, so I went to the nearby river to wash and wash." And your uncle Jack, seeing me clean when I came out of the chimney, thought he was as clean as me, so he washed his hands and went straight to the street. As a result, everyone in the street laughed and hurt their stomachs. They think your uncle Jack is crazy. "

Einstein couldn't help laughing with his father. When his father finished laughing, he solemnly said to him, "In fact, no one else can be your mirror. Only you are your own mirror. Taking others as a mirror, * * * may make yourself a genius. "

Hearing this, Einstein suddenly looked ashamed.
