1. The story of Marie Curie’s self-improvement:
Marie Curie, the great female scientist and the inventor of “radium” could have become a billionaire. But she refused wealth all her life, gave up her patent, and selflessly dedicated her radium invention patent to all mankind. She lived a simple and poor life all her life, and moved everyone with her selflessness! "Human beings also need dreamers, need Selfless in her career." This sentence she said is the best portrayal of her life.
This is a Baroque three-story apartment building with brown and pink walls. There is a small balcony in the middle of the second floor, which is the birthplace of Marie Curie. On November 7, 1867, Marie Curie was born in this ordinary residence, No. 16 Freta Street (Ul freta 16). This extremely ordinary residence is only 500 meters away from the Chinese Embassy in Poland. If it hadn't been for a small sign hanging at the door, I would never have guessed that this was the former residence of Marie Curie. The furnishings inside are very simple, displaying a profile of Madame Curie and some daily and work supplies. Unlike visiting other places, everyone inside was very quiet, and everyone finished visiting the former residence of this great and selfless scientist with tears.
In the era when Madame Curie was born, her native Poland was still under the rule of the Russian Tsarist invaders and was in the midst of internal and external wars. Although she was far away from home, she was still close to her heart. Hometown, I have always missed my motherland. In 1898, in commemoration of her native Poland, Marie Curie named her newly discovered element "Polonium", which means Poland. On July 6, 1934, Madame Curie was buried in Curie's tomb in Sausage, Paris. Her brother and sister sprinkled soil brought from her native Poland into the tomb...
2. The story of Madame Curie’s respect for her teacher:
In May 1932, the Radium Institute in Warsaw was established, and Madame Curie returned to her motherland to attend the inauguration ceremony. Many famous people surrounded him.
Just as the ceremony was about to begin, Madame Curie suddenly ran down from the podium, passed through the crowd holding flowers, and came to an old woman in a wheelchair, kissing her affectionately. He touched her cheeks and pushed him onto the podium in person. This old woman was Madame Curie's teacher when she was a child. Everyone present was moved and applauded enthusiastically, and the old man also shed tears.
This was the case with Madame Curie. After she became a scientist, she still did not forget the teacher who had imparted knowledge to her.
3. The story of Marie Curie’s study:
Decades ago, there was a little girl named Manyia in Poland who was very attentive to her studies. No matter how noisy the surroundings were, it could not distract her attention. Once, Manya was doing her homework, and her sister and classmates sang, danced, and played games in front of her. Manya acted as if she hadn't seen it, reading intently on the side.
My sister and classmates wanted to test her. They quietly set up a few stools behind Manyia. As long as Manya moved, the stools would fall down. Time passed minute by minute, Manya finished reading a book, and the stool was still upright.
From then on, her sister and classmates no longer teased her, and like Manya, they concentrated on reading and studying seriously.
When Manya grew up, she became a great scientist. She is Madame Curie.
4. Madame Curie’s growth story:
Mrs. Curie was born and grew up in Poland. At that time, Poland was under the rule of Russia. Mary had had enough of being a slave since she was a child. She privately accepted many ideas of resisting aggression and loved her motherland from the bottom of her heart. She vowed to fight for the liberation of her motherland. And learn. Her mother died when Mary was very young, and her father lost his job due to the subjugation of the country. He only relied on his previous savings and some money earned from teaching other children at home to support them. The family's life was very difficult. The difficult environment tempered the will of the Mary sisters. In school, they were all the best students and were deeply loved by their teachers.
Mary graduated from middle school and won a gold medal for her outstanding talent and learning.
But she could not continue to go to school, because in Poland under the rule of Tsarist Russia, female students were not accepted in universities. When she went to school in Paris, her family could not afford that much money. You should know that my sister, who also graduated with a gold medal, has been staying at home for three years, and her wish to go to school in Paris has not yet come true.
Mary returned home, and her father shed tears sadly because he could not afford to send his daughter to school. Mary persuaded her father while thinking of a solution. She and her sister discussed that she should be a tutor first so that her sister can study. After her sister graduates and gets a job, she can study for her. In this way, her sister took the money raised by the whole family and moved to Paris. Mary earned money while studying, and finally entered the Faculty of Science of the University of Paris in 1891.
All the difficult conditions did not affect Mary's study at all. She was always the first to come to the classroom early every day, sit down in the front row, and listen carefully to the teacher's lectures. At 10 o'clock in the evening, the lights in the library went out, and she reluctantly left and returned to her own home. In the hut, the kerosene lamp often stayed on until two or three o'clock at night. In just two years, she obtained two master's degrees in physics and mathematics. This pale girl wearing a shabby sweater graduated from the University of Paris with first place in 1893.
5. Madame Curie’s struggle story:
Mrs. Curie and the others borrowed a dilapidated storage room from a friend. Madame Curie cleaned it up and refurbished it. They used the money they had saved to purchase some necessary instruments and equipment, and the two began arduous research. The Curies carefully tested all the chemical reagents and minerals they could find one by one, and found that pitchblende was obviously radioactive. They determined that the ore contained some new radioactive element. Marie Curie conducted a series of treatments on dozens of kilograms of pitchblende under crude conditions, and finally found this new radioactive element. Marie named this new element after her motherland. This is "polonium".
"Polonium" was found, but the Curies did not stop, because in the process of refining "polonium", they found that the separated barium compound was more radioactive. According to analysis, this is another an unknown radioactive element. They called this element radium. The Curies disclosed this discovery to the world, and because no one had ever seen radium with their own eyes, many people were skeptical of the discovery. In order to prove the existence of radium, the Curies invested in a more arduous struggle to extract radium.
Without an experimental factory, they borrowed a broken wooden shed from a friend to build a factory; without funds to buy valuable pitchblende, they bought cheap waste slag. Madame Curie wore greasy work clothes and kept going in and out between the yard and the house. Sometimes she was adding coal to the yard to burn fire and smelting slag, and sometimes she was crystallizing concentrate in the house. The container weighing more than 20 kilograms was constantly being moved by Madame Curie. Moving in and out. Regardless of severe cold or scorching heat, the Curies worked day and night, refining tens of thousands of times, and struggled for four years. In 1902, the radium salt they dreamed of was finally separated.
In 1903, Marie Curie received the first female doctorate in history. In the same year, the couple won the Nobel Prize. Marie Curie became the greatest woman in human history. Her story inspired generations of young people to grow up, and her name was praised by hundreds of millions of people.

Research fields
1. The radioactive elements polonium (Po) and radium (Ra) were discovered.
2. Proposed the view that rays (now known to be composed of electrons) are negatively charged particles.
Scientific Achievements
In her experimental research, Madame Curie designed a measuring instrument that can not only detect the presence of rays in a certain substance, but also measure the intensity of the rays . After repeated experiments, she found that the intensity of uranium rays is proportional to the amount of uranium in the material, and has nothing to do with the state of uranium existence and external conditions.
Marie Curie conducted a comprehensive examination of known chemical elements and all compounds, and made important discoveries:
An element called thorium can also automatically emit Invisible rays come, which shows that the phenomenon of elements emitting rays is not just a characteristic of uranium, but a unique characteristic of some elements. She called this phenomenon radioactivity and the elements with this property called radioactive elements. The rays they emit are called "radiation."
At the end of 1902, Marie Curie refined one-tenth of a gram of extremely pure radium chloride and accurately determined its atomic weight. Since then the existence of radium has been confirmed.
Radium is an extremely hard-to-obtain natural radioactive substance. It is in the form of shiny, white crystals like fine salt. Radium has a slightly bluish fluorescence, and this is what makes it so beautiful. The light blue fluorescence blends into a woman's beautiful life and unyielding faith. In spectral analysis, it is different from the spectral lines of any known element.
Although radium is not the first radioactive element discovered by humans, it is the most radioactive element. Using its powerful radioactivity, many new properties of radiation can be further identified. to enable further practical application of many elements. Medical research has found that radium rays have very different effects on various cells and tissues. Those cells that reproduce quickly are quickly destroyed once radium is irradiated. This discovery made radium a powerful tool in the treatment of cancer. Cancerous tumors are composed of cells that reproduce abnormally rapidly, and laser rays can damage them far more than the surrounding healthy tissue.
This new treatment method was quickly developed in countries around the world. In the French Republic, radium therapy was called Curie therapy. The discovery of radium fundamentally changed the basic principles of physics and was of great significance in promoting the development of scientific theories and their practical applications.
