Newton: A Tale of Two Isaacs
Friends such as Newton, a world-famous scientist, give gifts to cats and dogs. Newton was very unhappy. He took care of his new friends and made it convenient for cats and dogs to enter the house. Newton asked him if he wanted to dig two holes. Newton replied: Can dogs and cats dig holes?
Newton's childhood happiness, three months ago, his father's two-year-old mother remarried to a neighboring village. Newton lived with his grandmother and squandered money. They only spent some pocket money on handicrafts, pooled together to buy tools such as saws and hammers, and knocked and knocked in hidden places.
Newton learned to concentrate on boiling eggs and thinking about numerical formulas, but he accidentally made a table and threw the eggs into the pot. The problem of calculation began in the morning. I forgot to eat my stomach. It's already dusk. The study is full of fresh air. I suddenly thought of going to the study for dinner, and immediately went into the study to look at the table and calculate the draft. I forgot to do anything when I was eating, so I immediately bent over my desk and worked hard.
Second, the story of De
Di, a world-famous inventor, started selling newspapers when he was twelve years old. He scrimped and saved, bought books and newspapers, made experimental instruments, and picked up some bottles and cans from the garbage.
When Di 12 years old, the train sold newspapers. On the train festival, passengers are given special carriages to smoke, and the carriages are allowed to occupy the corner. The bottles and cans of chemicals have been moved, the newspapers have been sold out, and all kinds of interesting experiments have been done.
The train was waiting for a violent vibration, and the bottle of white phosphorus fell. Phosphorus catches fire when it meets air. Dee caught fire and put it out when it was washed away. Dee was so angry in the car that he threw away all the experimental things and slapped him hard that he was deaf. Dee never shakes her head. He scrimped and saved, resumed his chemical experiments and burned his clothes with sulfuric acid. Nitric acid almost blinded me. I was not frightened by the danger, so I stubbornly did the experiment.
De tried out the electric lamp, found a cheap filament and learned to do less experiments. The lab was too tired to work for dozens of times, so he lay on the test bench and slept. After unremitting efforts, he finally found a suitable filament and invented the electric light. Di invented the movie and the phonograph ... and invented 1000 kinds of things.
Third, the story of the husband.
A Polish scientist with a husband won the Nobel Prize twice for his research on radioactive phenomena. Mary studies hard. She is keen on learning anything. She showed tenacious enterprising spirit everywhere. At the beginning of each course, she won a gold medal when 15 was old. Her father graduated with honors. Previously, she studied physics in St. Petersburg. Her hunger and thirst are deeply influenced by her strong career. She read all kinds of instruments in her father's laboratory, which made her eager to explore the world. Her family environment allows her. At the age of 65,438+09, I began to be a tutor and prepared various courses for myself. At the age of 24, I finally listened attentively to every class with a strong thirst for knowledge. Studying hard makes my body better and better, but I am among the best. I just surprised the professor with the same envy. I took the bachelor's degree examination in physics, and 30 candidates got the second place, and won the second place with excellent results.
Fourth, the story of Darwin.
Darwin cultivated the soil with trees in his mother's garden. Mother said: soil is precious, and soil can be cultivated. Don't look outside the grass, feed fat cattle and sheep, and I will drink milk and eat meat. I only eat wheat and cotton, but I can't wear it. The soil is too precious.
Darwin asked: Mom, earth can make dogs.
Yes! Mom smiled and said, mom, dog, dirt.
Darwin asked: My mother, mother and grandmother,
Ah! All mothers.
Good morning, mom. Who is it?
Emperor!
Who is the emperor?
Mom replied. Darwin said: son, I said that everything in the world is mysterious, just like a tree. Come on, there are some mysteries waiting to be solved!
Darwin liked flowers, trees, birds, insects and fish since he was a child, and he still maintains a strong interest. Riding horses, hunting, fishing, collecting minerals, catching insects, and drilling into the Woods to observe the habits of birds. Darwin said that it is really important to explore and think about the whole world. He observed and meditated, even forgetting the danger. Walking in Darwin's ancient castle is like being lost in thought. Why did he walk so slowly that he suddenly stepped on the air and the battlements fell down?
V. Joule's Story
Joule, a famous British scientist, did some electrical and thermal experiments himself.
Joule's brother began to travel in the country during the holiday, and Joule didn't forget to do physics experiments while playing. He found a lame horse, led by his brother, and hid it quietly. The horse wanted to try something and was stimulated by the current. He wants to see everyone's reaction. Now the horse jumped up and almost kicked his brother.
Although the danger didn't affect Joule's mood in the experiment at all, my brother rowed the boat and surrounded the lake with mountains. Joule wanted to try a musket full of gunpowder, and pulled the trigger, but with a bang, a flame burst out of the muzzle and burned Joule's eyebrows, almost scaring my brother into the lake.
The sky is full of lightning and thunder. Just trying to hide from the rain, Joule found that thunder could only be heard every time there was lightning. Joule took his brother to shelter from the rain and climbed the mountain with a pocket watch. Joule was almost in a hurry to tell the teacher when he was doing the experiment, so that the teacher could look at Joule and laugh. Explanation: Photoacoustic travels fast and the speed of sound is slow, so I always want to see lightning and listen to thunder. In fact, lightning and thunder are the same.
Joule is more fascinated by learning knowledge. After careful observation and calculation, he finally discovered the law of conservation of thermal work and energy.
Six, Franklin's story
17526 In the suburb of Philadelphia, USA, dark clouds were gathering, lightning flashed and thunder broke, and the grass was wide and short. Two people were flying kites with great interest, and lightning struck the clouds and scribbled on them, then thunder and rain poured down.
The audience shouted: William is standing in the thatched cottage, straining the kite string. The lightning track lights up and the thunder is loud. William shouted, Dad, the quick-looking man looked in the direction and saw the taut hemp rope. Some slender fibers stood up and were very happy. He shouted: the electric lead and hand slowly approached the hemp rope and the copper key, and suddenly it seemed to fall, and it was numb with pain. He climbed up with a Leyden bottle to pick up the copper key, and the spark of discharge held up his home like a Leyden bottle.
Take power Franklin William Franklin was just a great politician and diplomat. The Declaration of Independence introduced the first American ambassador abroad.
Kite experiment Franklin wrote an article on the electrical identity of lightning. This paper expounds the essence of lightning, and puts forward the idea of making lightning rod to protect buildings from lightning strike. Franklin invented the lightning rod, which spread all over Britain, Germany, Europe and America.
Seven, the story of Nobel
Nobel's father is a genius inventor. He tends to study explosives, especially explosives influenced by his father. Nobel showed a tenacious and brave character. After his father began to experiment with explosives, his interest quickly turned to application with his father's experience in studying explosives.
1862 the study of nitroglycerin in early summer is full of danger, sacrifice and hard journey. Every moment of death is accompanied by explosion experiments, explosions, explosions. All the assistants died, even his brother was not spared. The explosion accident dealt a great blow to Nobel's father. Neighbors were afraid for a long time and accused the Nobel government of allowing Nobel experiments.
Nobel indomitable laboratory moved the ship to a suburban lake to continue the experimental menstrual research, and finally found a substance that is not easy to cause explosion-mercury fulminate, which was used as an explosive detonator to solve the problem of explosive detonation.
Nobel patented 255 inventions and only 129 explosives, but he was still obsessed with the research of new explosives when he died.
Eight, the story of Zhong
The inventor of electricity was named Bell, who moved to the United States for a long time at the age of 184724 and joined the United States at the age of 1873. A linguistics professor in Boston tried to connect telegraph lines with several messages. Imagine that his wife Mabel Hubbard and his father-in-law supported Bell's father's rich husband's experiment and provided the necessary financial support before Mabel became deaf.
Several of Bell's friends wanted to study telegraphy, but the inventor only wanted to complete the work of transmitting sound. First, he tried harmonic telegraphy-connecting two wires with a charged reed group and assembling two harp modules, each with the same frequency. Bell's two harps are hung with magnetic membranes to imitate ear organs.
In fact, thomas watson, Bell's assistant, fiddled with the conductor of the reed clock and listened to the plucked strings in the next room, which led to the progress test. Cheng Bei encountered fewer difficulties and sought guidance and help from some famous physicists, such as Helmholtz, joseph henry and Dee.
18763 June 10, Bell's transmitter shouted: Watson asked me to go to the lab to find Watson's assistant first. Listening to the call, I jumped into the laboratory like crazy and ran to Bell's dormitory road, calling: I heard Bell calling me, I heard Bell calling me. ...
A new communication history of 1877 was unveiled when the class started. The first transmission news telegram was sent to Boston's Le Monde, marking the establishment of Bell Electric Company in 1878.
Nine, Stan's story
Stan, a great physicist in the 20th century, likes hand and brain manual classes and wants to be a wooden bench. When the bell rang, he was scrambling to take his own work and give it to a beautiful and strict teacher. Stan didn't take his own work. The teacher looked at the boy generously and believed that he could hand in an assignment.
Secondly, Stan made a rough bench for the teacher, and the legs of the bench were nailed up, full of expectation. The teacher said to the class: Who saw a bad bench? The students snickered and shook their teachers' eyes at Stan and said, I think the world is worse than the classroom.
Stan blushed and walked up to the teacher, sure that the teacher said: the teacher is worse than the bench. Everyone in the classroom is confused. Stan walked away from his desk and took two rough wooden stools. He said: my second production has just been given to the teacher, and the third wooden stool is better than the first two.
Everyone laughed at the teacher's cordial reflection on Stan and his admiration and approval in the same direction.
The story made me see Stan's tenacity and satisfaction, and then put it into production. * * * Doing three benches is better than doing the first two benches. Cheng Stan showed his attitude towards himself. In everything, he should strive to fully release his energy, satisfy his achievements and give play to his potential.
X. The Story of Watt
Because of her poor family, Watt Yuying opened her own watch shop. Watt is a musical instrument repairman in Glasgow. He is very clever. He will take time to listen to the professor and play some musical instruments himself.
1764 Glasgow closed the stage and asked for the maintenance of Newgate steam engine. Give the task to Watt Watt. The work is very hard, such as panting, jumping and walking with heavy load. Attention needs to be improved. The main cylinder wastes a lot of heat with the steam cooling and heating, which can keep the temperature low. We need to rent a cellar from money to collect some scrapped steam engines to build a new machine.
Watt fiddled with several machines, and finally got the new machine ignited to test the air leakage at the cylinder. Watt wrapped himself in felt and tarpaulin for several months, trying to solve the problem. Watt didn't give up his efforts, and finally designed a cylindrical condenser with a thermal efficiency of three times. Watt feels that the future is bright. Ask Professor Black some theoretical questions. Introduce and know the invention of boring machine. Wilkin technician immediately made cylinder plug with boring barrel, which solved the problems of pain and air leakage.
1784 watt steam engine has been equipped with crankshaft and flywheel plug, which is constantly pushed by steam from both sides and then forcibly adjusted. The first real steam engine in the world was born.
