How to become a scientist?

In fact, the so-called scientists should be people who have expertise in a certain field and continue to study in depth. Yes, becoming a scientist is a good ideal. Edison's inventions and ideas failed or were rejected more than once, but this did not prevent him from becoming a great man.

My advice to you is: when you find your interest in invention and creativity, what subject does it relate to? Physics? Math? Or any other subjects? If you find it right, go on. Your preparation work is to know the history of the subject you want to study in detail, some existing theoretical viewpoints, and lay a good foundation for learning.

I hope it will help your life:)

Bauer Hurst is an American scientist who studies snake venom. When he was a child, he saw that thousands of people in the world were killed by poisonous snakes every year, and he decided to develop an anti-venom drug. He thought that people with smallpox would be immune, but could they be immune after being bitten by poisonous snakes? Can antitoxic substances produced in the body be used to resist snake venom? He imagined that it was also possible. So from the age of 15, he injected himself with a small amount of snake glands, and gradually increased the dose and toxicity.

This experiment is extremely dangerous and painful. Every time he is injected, he will be seriously ill. The snake venom of various snakes has different components and different modes of action. Every time a new kind of snake venom is injected, the original anti-venom substance will not be competent and will be tortured by the new anti-venom substance. He was injected with 28 kinds of snake venom. After a dangerous and painful experiment, I finally got something. Because of its own anti-toxicity, King cobra, Indian blue snake and Australian tiger snake have all bitten him, but every time he survived. Blue snake is extremely toxic, and Hester is the only living person bitten by blue snake in the world. He was bitten by a poisonous snake 130 times, and he was safe every time. Hester analyzed the anti-venom substances in his blood and tried some anti-venom drugs, which have treated many people bitten by poisonous snakes.

Chemist devoted to science, Mova San Henri Mojssan1852-1907.

Movado is a famous French chemist. He made elemental fluorine (F2) in 1886, so he won the Nobel Prize in chemistry.

1906, the Swedish Nobel Foundation announced that it would award Movasan a prize of 65,438+million francs, "in recognition of his outstanding contribution to the preparation of elemental fluorine and his invention of Mohs electric furnace." In 65438+February of the same year, a large number of students and friends of Movado held a grand celebration meeting in the conference hall of Paris University to celebrate the 20th anniversary of the preparation of elemental fluorine by Movado. At the meeting, 54-year-old Movasan made an impromptu speech. At the end of his speech, he said: "We can't rest on what we have achieved. After reaching one goal, we should keep moving towards another. One always has to set a goal for himself. Only in this way can he feel that he is a real person, and only in this way can he keep moving forward. " In the cause of science, Movasan has made great achievements and is a generation of scientific masters. However, his road to success was very bumpy, and he experienced many difficulties and dangers.

The drugstore apprentice who "came back to life"

1870 At a crossroads in Paris, there is a very famous old drugstore called Bentley Pharmacy. One day, the shop was very quiet, except that the pestle and mortar made a slight and even sound. It was several apprentices grinding medicine, and an old pharmacist with reading glasses was turning over a thick book, looking for the chemical molecular formula of medicine. At that time, medical chemistry was very developed in Paris, and chemists and doctors believed that chemical methods were the magic weapon to save lives and overcome death. However, limited by the level of scientific development, chemicals at that time were only effective for a few very simple diseases. Among the apprentices in the pharmacy, there is a clever young man named Movasan. Just as he was grinding the medicine carefully, suddenly, the door of the drugstore was knocked open and a middle-aged man stumbled in. His face is brown, he is sweating, he has difficulty breathing, and his eyes are terrible. "Help-help-"he whispered out of breath. Everyone in the drugstore put down their work and gathered around him. "What's the matter with you?" The old pharmacist asked, "I am poisoned by arsenic." I took it as medicine, and now-the medicine has worked. " I have a terrible stomachache. "The old pharmacist slowly took off his glasses, shook his head and whispered," this time there is no way out. There's nothing the best doctor can do. Do you have anything else to say? Please speak quickly and we will tell your family about your will. "The atmosphere was so tense that everyone was silent." Please wait a moment! "Movasan said loudly. He pushed his way through the crowd, pushed to the front, looked at the patient, turned around and took some antimony potassium tartrate and ferric chloride from the medicine rack to give the patient some "people", and then gave the patient some other medicines. As a result, the patient's condition soon eased. After two days of treatment, the patient recovered completely. Afterwards, a tabloid in Paris reported the incident with the title of "Drugstore Apprentice from the Dead", and many Parisians knew Movasan's name.

Study hard for ten years ―― study hard for many years.

Movado 1852 was born in an old house in Paris on September 28th. When he was 10 years old, his family moved to a small village in Seine province because of the pressure of life. Later, people renamed this small village Mozhen to commemorate Mowasan.

Movasan's father is a railway worker, with a meager income, barely maintaining the minimum living at home and no money for his children to study. Movasan 12 years old only goes to primary school, and helps the family do some housework after school. The whole family often eats the cheapest food and has no money to buy books and stationery for Movasan. However, all this did not affect Movasan's academic performance. At school, he is among the best in every exam. Soon. The teachers all fell in love with the poor and clever child. When he was a teenager, Movasan liked studying chemistry best. He borrowed all kinds of chemistry books from his teacher and studied eagerly. At the same time, he also did various chemical experiments by himself. However, due to the very difficult family life, he was forced to leave home and work as an apprentice in a pharmacy in Paris.

After becoming an apprentice, Movasan still insisted on studying hard. 1874, passed the exam and got the high school diploma; 1877 passed the examination and obtained the college diploma and bachelor's degree. He taught himself for ten years, and later he was admitted as an intern of the famous French chemist Frommie, equivalent to a graduate student now. Under the guidance of Professor Debray, he passed the thesis defense of "On Natural Iron" and obtained a doctorate in physics from Paris University. In the process of learning, Movasan was never satisfied with his achievements and was not afraid of any difficulties. Sometimes he consults materials for more than ten hours. Once he worked in the laboratory for more than 30 hours without eating or drinking. When his classmates walked into the laboratory, they saw him pale, with sunken eyes and black eyes, leaning back in the chair feebly. "Come on, send him back to his room. 1 "His classmates and experimenters were too many, and the chef quietly sent him back to his room, and he came back in less than half an hour. "Are you dying?" The students all blamed him. "You know, the experimental data will be available soon!" Movasan answered firmly. The classmate had no choice but to let him do it.

Movado studied and worked tenaciously in this way, which became the basis for his great contribution to science later.

Fight death

1878, when Movasan was internship in Fromy laboratory, his classmate Afangman said to him with a bottle of medicine: "This is potassium fluoride, and no one in the world can make elemental fluorine!"

"Can't our teacher, Professor Fromy, come?" Movasan asked.

"I can't do it." Arman was very emotional. He said, "In the past, everyone failed to do experiments with elemental fluorine. The great chemist David also tried to make it, but it was unsuccessful and poisoned. 1836, Knox brothers, Irish Academy of Sciences. When making simple atmosphere, my brother died of poisoning and went to the hospital. In addition, Runat in Belgium and Dangerous Cray in France were both poisoned while doing this experiment. The famous Gay-Lussac almost died. You know that. Dear Devasan, fluorine is the element of death, so don't touch it. "

"I'm not afraid. Arman, I must make elemental fluorine in the future! " Movasan answered firmly.

"Then you should be more careful!" Arman cares about 1 again.

After this lab talk, Movasan added a concern that elemental fluorine always haunted his mind. Elemental fluorine, elemental fluorine, death element, death element He sometimes mumbles in his dreams. How can we uncover the secret of this "death element"? Movasan has been thinking about this problem.

1885, movado began to make fluorine. At first, he wanted to do experiments with phosphorus fluoride and pure oxygen. At that time, the periodic law of chemical elements was discovered for more than ten years, and the chemical potential of fluorine and oxygen was not understood at all, so his experiment began to be blind. So contrary to expectations, Movado not only failed, but also burned two expensive platinum tubes for nothing. He failed in several experiments in succession. "It's over, it's over, it's useless!" Movasan sighed.

Movasan has a rich knowledge of chemistry and chemical history. After many studies, he thinks that fluorine must be the most active nonmetallic element, so it can't be prepared at high temperature, nor can it be prepared by general chemical methods, such as displacement reaction. "It seems that electrolysis is the only way." He pondered over it. Movasan imagined that elemental fluorine can be obtained by the following formula:

2 ASF 3->； 2As+3 F2 2pf 3->； 2P +3F2

Therefore, it is necessary to obtain arsenic fluoride (AsF3) or phosphorus fluoride (PF3) first, and then create the conditions for preparing fluorine by electrolysis. Mr. Movado produced qualified but toxic arsenic fluoride and phosphorus fluoride, added a small amount of potassium fluoride (KF) into it, ground it evenly, installed an electrolytic device and applied direct current. At first, the reaction went smoothly, and bubbles appeared on the anode, but after a while, the anode was covered with arsenic or phosphorus, and the reaction slowly stopped. Movasan also felt weak, his heart was beating violently, he was short of breath, and he walked with difficulty. "Don't I also like chemists in history, died of fluorosis, absolutely not! Fluorine has not been made yet, so leave the lab quickly! " Movasan thought. However, he can't go anywhere! But still conscious, he struggled to pick up his right hand, turn off the switch, and then collapsed on the sofa. Hour after hour, when he woke up, he saw his wife Lu Geng standing beside him. She was crying in a low voice with tears all over her face.

Dear Lu Geng, I told you never to come to the lab. It's full of drugs, even the air is the same, which will affect your health ... Movasan said to his wife with difficulty.

"Dear Movado, if I don't open the Phoenix window, I don't know if you will wake up ... look in the mirror. You are yellow and thin now, You Lan. I'll call the doctor and he'll let you rest for a month. " His wife Lu is even more unhappy.

"I can't rest for a day now, and the work of making fluorine will be successful!"

Movado began to do experiments again. It took him four days to grind a piece of fluorite into a U-shaped tube and put a mixture of arsenic fluoride, phosphorus fluoride and potassium fluoride into the tube. Electrodes are installed at both ends of the U-shaped tube, and the power supply is connected. Soon, one bubble after another appeared above the anode. The elemental fluorine, which is called the "death element", is finally taken out. Movasan shouted excitedly, "Fluorine! Fluorine! " This is June 26th. 1886: Miracle. At that time, Movasan was only 34 years old.

Expert testimony

Movasan submitted a written report to the French Academy of Sciences after producing fluorine. The Academy of Sciences sent a three-person expert group to evaluate his experiment. After the preparatory work, Movasan redone the experiment in front of the experts. After the current was connected, his device seemed to be disobedient. After a few minutes, not even a bubble was produced. Movasan was frightened. He sweated and repeatedly operated. Strangely, this device just doesn't produce fluorine gas, which makes him very ashamed and anxious. Fortunately, the expert had a good attitude, and they encouraged him to do it again in a few days. After the expert left, Movasan carefully checked his equipment. He found the reason simple, even a little ridiculous. Because potassium fluoride was added too little, the U-shaped tube was not conductive, so three days after no fluorine was produced, he conducted his experiment again in front of experts and successfully collected 4 liters of fluorine gas. Movasan died in 1907, the year after he won the Nobel Prize, at the age of 55. His long-term exposure to drugs has seriously damaged his health. After his death, the world chemical community expressed deep condolences to him. Soon, his wife Lu Geng died of grief. Their only son, Louis, donated his parents' legacy of 200,000 francs to the University of Paris as a scholarship, one of which was called the Movado Prize in Chemistry in memory of his father. The other is called Lugan Pharmaceutical Award in memory of his mother. With such a good son, both Movado and Lu are under the grave, and they are at ease.

Movasan had many achievements in his life. He once invented the electric furnace named after him-Morse electric furnace, which can melt all kinds of metals simply and quickly. He used it to make more than a dozen metals, such as uranium, tungsten, vanadium, chromium, titanium and aluminum. His wife Lu was the first person to use aluminum pot in the world, and the aluminum pot was made by Movasan himself in the laboratory with his electric stove. Movasan was also the first chemist in the world to make synthetic diamonds. He is elegant and likes poetry, music and painting. His bedroom is covered with famous paintings.

Movasan won many honors in his life. He was once hired as an honorary professor at Hall University, and Russia also awarded him the title of honorary academician of the Academy of Sciences. Author of fluorine and its compounds, electric furnace and other works.

Go your own way and let others talk.

Want to be a scientist?

It's actually quite simple. Now drop out of school, stay at home, think whatever you want every day, and become a scientist.

In fact, scientists are a general term, not to say that there is such an industry.

You have made breakthroughs and innovations in your work. In fact, you are a scientist. Blindly pursuing innovation and development will only leave you with nothing.

The launch of a spaceship is a scientific crystallization created by scholars or workers like astronautics. Don't lose heart, work hard and you will succeed.

You can become a scientist if you study science first. There is little hope in China. You can only study politics well in China. If you can get a scholarship to go abroad, there is hope.

I don't mean to hurt you, but it's hard under this educational system that stifles personal nature, advocates official position and worships money worship!

When we were young, 8 children in 10 wanted to be scientists. What happened in the end? That's why there are no Nobel Prize winners.

I think what you have to do is: stick to your ideals. This is very important, because you will be constantly harassed and assimilated by the outside world, making it difficult for you to persist. Doing scientific research is boring, the basic skills must be solid, and there can be no falsehood and impetuousness. Combined with China's attitude towards basic scientific research, this road you have chosen is really difficult. You have seen all kinds of advertisements on TV that claim to cure all diseases, copying the "high-tech products independently developed by China" produced by foreign expired patented technology, alas ~ ~

I hope I can help you.

Study hard, you are too early, I am only 12 years old!

"If you want to see something that is not good enough, you should perfect it" is impossible. It's so hard that you can do whatever you want.
