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.

Hua is a famous mathematician in China, born in a poor family, and has taken on the heavy responsibility of the whole family for his father since childhood. But whenever he is free, he borrows some math books. He taught himself all the math courses in senior high school and junior college in five years. /kloc-contracted typhoid fever when he was 0/8 years old. For this reason, everything in the family was used up, but his condition did not improve. Fortunately, under the careful care of my family, I finally saved my life, but I became a lifelong disability. Later, under the care of the old middle school teacher, I worked as a handyman in this middle school. He borrows books whenever he has time. His disabled left leg often hurts badly. He is still bent on chopping waves in the ocean of the kingdom of mathematics, leaving behind his pain, the hardships of life and the injustice of the world. ...

179 1 year, Faraday was born in a poor blacksmith's house in the suburbs of London. Father's income was meager, he was often ill and had many children. Faraday didn't even have enough to eat when he was a child. Sometimes he can only eat one loaf of bread a week, let alone go to school.

When Faraday 12 years old, he went to the streets to sell newspapers. When I sell newspapers, I can read from them. /kloc-at the age of 0/3, Faraday entered a printing factory as an apprentice in book binding. He bound books while studying. Whenever he has free time, he leafs through the bound books. Sometimes even on the way to delivery, he walks and watches. After several years of hard work, Faraday finally took off the hat of illiteracy.

Gradually, Faraday can read more and more books. He began to read the British Internet Encyclopedia, often reading late into the night. He especially likes books on electricity and mechanics. Faraday had no money to buy books, so he used waste paper from the printing house as a notebook, extracted all kinds of materials, and sometimes illustrated himself.

By chance, Dances, a member of the Royal Society of England, came to the printing factory to check his works and stumbled upon Faraday's Manuscript. When he knew that it was a note written by a bound apprentice, he was surprised, so Dance gave a lecture ticket to Faraday Royal College.

Faraday came to the Royal College with excitement. It was David who made this report, a famous English chemist at that time. Faraday stare big eyes, very attentively listening to David's lecture. After returning home, he compiled the lecture notes into a book as a chemistry textbook for self-study.

Later, Faraday sent his carefully bound chemistry textbook to Professor David with a letter, which said, "I am very willing to escape from business and enter the field of science, because according to my imagination, science can make people noble and amiable."

David was deeply moved when he received the letter. He admired Faraday's talent very much and decided to recruit him as his assistant. Faraday was very diligent and soon mastered the experimental technology and became David's right-hand man.

After half a year, David will make a scientific research trip to the European continent, visit famous scientists in European countries and visit chemical laboratories in various countries. David decided to take Faraday abroad. In this way, Faraday traveled in Europe with David for a year and a half, met famous scientists such as Ampere, gained a lot of knowledge and learned French.

After returning home, Faraday began to conduct independent scientific research. Soon, he discovered the phenomenon of electromagnetic induction. 1834, he discovered the law of electrolysis and shocked the scientific community. This law is named Faraday's law of electrolysis.

Faraday, relying on hard self-study, stepped into the ranks of world-class scientists from an apprentice who had never attended primary school. Engels once praised Faraday as "the greatest electrician to date".

1867 On August 25th, Faraday sat in his study and died at the age of 76. Because of his great contribution to electrochemistry, people use his surname-"Faraday" as the unit of electricity; Use the abbreviation of his surname-"Farah" as the unit of capacitance.

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.

Six short stories of scientists (100 words)

) 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.
