The story of the scientists hard work

1.Newton was a world-renowned scientist. Newton was very fond of animals as a child.

Once, his friend gave him a dog and a cat, Newton was very happy to receive the gift, and took care of his new friend with great care, in order to make it easier for dogs and cats to enter and leave the room, Newton dug two holes by the door, one large and one small, and someone asked him, why do you dig two holes, one large and one small, Newton said, "Can a dog pass through the cat hole?" ”

Newton's childhood was unfortunate, as his father died three months before he was born. When she was two years old, her mother remarried to a neighboring village. Newton had no choice but to live with his grandmother.

He never spends money indiscriminately, his hobby is to engage in some small crafts, gather pocket money, buy saws, maces and other tools, and hide in the house as soon as school is over.

Newton was very focused when he was studying. Once, when I boiled an egg, I thought about the mathematical formula and threw my watch into the pot as an egg. Another time, I calculated a problem from the morning and forgot to eat lunch.

By the time he felt hungry, it was twilight. He stepped out of the study, and a fresh breeze felt unusually fresh. Suddenly it occurred to me:

Didn't I go to dinner? How did you get to the courtyard! So he immediately turned back and went into the study again.

When he saw the calculation draft spread out on the table, he forgot all about eating, and immediately sat down at the desk and calculated nervously.

2.Albert Einstein was born on March 14, 1879, in Ulm, eastern Germany, of Jewish descent. His father, Heilmann Einstein, was very talented in mathematics, but his parents had no money for him to go to school, so he had to give up his studies to start a business.

At a young age, Einstein began to learn**, and at the age of six he began to practice playing the violin, and ** almost became Einstein's"Second career", the violin accompanies him for life.

Before Einstein went to school, his father gave him a compass (compass), and the needle of the compass always pointed to the north and south poles, which made little Einstein study and fascinate for a long time, and until he became an adult, he still remembered this thing that impressed him. Another experience also left a deep impression on him. After a few years of schooling, he received a textbook of Euclidean geometry, in which many axioms were so unquestionably argued that he was so curious that he could not follow the course, but learned it in one sitting.

Faraday. He worked extremely diligently, and after nearly 10 years, in 1831 he finally discovered the principle of electromagnetic induction.

Ohm persevered in his scientific research in a lonely and difficult environment, making his own instruments. Finally, after many experiments, the famous Ohm's law was finally proposed in 1827.

Examples of people need to reflect the perseverance and hard work of scientists, and the story of Bauer Hasted is used here as an example.

Here's how: Bauer Hayside is an American scientist who studies snake venom. As a child, he saw thousands of people around the world being bitten by poisonous snakes every year, and he was determined to develop an anti-poison.

He thought that if a person suffers from smallpox, he will develop immunity, and whether it is possible for a poisonous snake to bite and develop immunity, and whether the antivenom produced in the body can be used to resist snake venom, he imagined that this is also possible.

Therefore, from the age of 15, he injected himself with a tiny amount of venomous snake glands, and gradually increased the dose and toxicity. Such trials are extremely dangerous and painful. With each injection, he had to get seriously ill.

The venom components of various snakes are different, and the mode of action is also different, and each time a new snake venom is injected, the original antivenom is not competent, and it has to be tortured by a new antivenom.

Hayside analyzed the antivenom in his blood and tried to develop some anti-venom drugs, which have treated many people who have been bitten by poisonous snakes. He has been injected with 28 kinds of snake venom. After never giving up the experiment, there is finally a harvest.

Due to his own anti-toxicity, the king cobra, the Indian blue snake, and the Australian tiger snake have all bitten him, but each time he escapes from the side of death, the blue snake is extremely poisonous, and Hasted is the only person in the world who has been bitten by the blue snake and survived. He has been bitten by poisonous snakes a total of 130 times, but he still does not give up on contributing to the cause of human health.

Kiss : There are the following scientists:1

Stephen Hawking: Suffering from amyotrophic lateral sclerosis, he is known as the most outstanding theoretical physicist after Albert Einstein and has made great contributions to human science. 2.

Hua Luogeng: He has made important contributions to the development of mathematics in China and enjoys extensive influence at home and abroad. 3.

Lu Xun: During his lifetime, he wrote a large number of essays, essays, and translations, and made significant contributions to the emergence and development of China's new culture. 4.

Thomas Edison: An American scientist and inventor who brought electric lights and movies to the world, and many of his inventions greatly promoted the development of human society. 5.

Zhang Heng: An ancient Chinese scientist who invented instruments such as the geodynamic instrument and the wind meter, and made outstanding contributions to ancient Chinese astronomy and mechanical technology. 6.

Marie Curie: Polish scientist who discovered the radioactive elements polonium and radium and used them for **cancer. 7.

Chen-Ning Yang: Chinese-American physicist who has made landmark contributions in the fields of particle physics, statistical mechanics, and condensed matter physics. 8.

Fermi: Italian-American physicist who has made significant contributions to the fields of nuclear physics and cosmophysics. 9.

Thompson: British physicist who discovered electrons in cathode rays. 10.

Marie Curie: Polish-French physicist and chemist who discovered radium and polonium. The examples of these scientists show their perseverance and diligent research spirit, and their achievements have made significant contributions to the development of human society and the progress of Qinghao.

It took Marie Curie 45 months to extract radium from waste slag.

Edison failed a thousand times when he invented the electric light, and finally succeeded... ==American physicists Michelson and Morey, through the Michael Morey experiment, finally proved that the speed of light is eternal, and that there is no such thing as an ether.

Albert Einstein worked tirelessly to write the theory of general relativity that solved the precession of Mercury's perihelion.

Edison: Edison tried to make electric lights, and I don't know how many experiments he did in order to find a filament that was cheap and could be used for a long time. He often worked in the laboratory for dozens of hours in a row, and he was so tired that he lay down on the laboratory bench and slept for a while.

With such unremitting efforts, he finally found the right filament and invented the electric light. Later, Edison invented the motion picture and the phonograph, ......He invented more than 1,000 things in his lifetime.

Edison failed thousands of times before he finally invented the electric light.

Albert Einstein worked tirelessly to write the theory of general relativity that solved the precession of Mercury's perihelion.

Newton, Newton was hit by an apple back then, but he didn't think the apple hit him, but wondered why the apple hit him, so he discovered gravity after hard work.

Edison's invention of the electric light failed thousands of times, and finally succeeded once.

It tells the story of the ancient and modern Chinese and foreign celebrities, and hopes that the children can absorb the persistent, fearless, tenacious and fighting spirit of outstanding people, and better determine their life goals, improve their quality in the competitive modern society, and intentionally cultivate good learning, living habits and beneficial hobbies.

In order to find a filament that is cheap and takes a long time, I don't know how much I did.

He often worked in the laboratory for dozens of hours in a row, and he was so tired that he lay down on the laboratory table and slept for a while. After such unremitting efforts, he finally found the right filament and invented the electric light. Later, Edison invented the motion picture and the phonograph, ......

He invented more than 1,000 things in his lifetime.

Edison, who went through a lot of hardship, invented the light bulb. Since then, many inventions have been invented that have benefited mankind.

It took Marie Curie 45 months to extract radium from waste slag.

Edison, because Edison invented the electric light bulb.

Edison invented the electric light bulb.

Albert Einstein, Edison, three books.
