The buildings of Warsaw's Old Town were restored and rebuilt at a later date, but this does not affect the appreciation of its beauty, and there are many attractions in the Old Town, such as the mermaid statue, the Royal Palace, the Old Town Square and the Marie Curie Museum.

Qu Lihua and Meng Wenjie are both familiar with the story of Marie Curie, and now Professor Chen Qi will review it for you again.

Marie Curie was born on November 7, 1867 in Warsaw, Kingdom of Poland, to a family of secondary school teachers, the son of Ulradislav Skrodowski, a mathematics teacher, and Bronislava Berguska, the headmaster of a girls' boarding school.

Both parents are intellectuals, Marie Curie was born in a good family, she can receive a good education from an early age, Maria is five, and has three sisters and one brother, namely Sophie, Brony Schlava, Helena and brother Joseph.

There are many brothers and sisters, there are many people in the family, and growing up in a big family, life is still very happy.

Marie became acquainted with a lecturer at the Sorbonne, Pierre Curie, her later husband, and the two of them often worked together on radioactive material to tons of industrial waste, since the total radioactivity of the ore was greater than the radioactivity of the uranium it contained.

In 1898, the Curies made a logical inference about this phenomenon that bituminous uranium ore must contain some unknown radioactive component, which is far more radioactive than uranium, and on December 26, Marie Curie announced the idea of the existence of this new substance.

In the years that followed, the Curies continued to refine the radioactive components of the bituminous uranium ore, and after unremitting efforts, they finally succeeded in isolating radium chloride and discovering two new chemical elements, polonium and radium.

Because of their discovery and research on radioactivity, the Curies and Henri Becquerel were jointly awarded the Nobel Prize in Physics in 1903, making Marie Curie the first woman in history to win the Nobel Prize.

Eight years later, in 1911, Marie Curie was awarded the Nobel Prize in Chemistry for her successful isolation of radium.

After the death of her husband, Marie Curie's life fell into a glacial state, which was a heavy blow to her, the loss of her husband, so that Marie Curie was emotionally frustrated, and later because of the scandal with Paul Langevin, suffered some criticism, emotional frustration, and took a detour.

In the end, Marie Curie survived the storm and devoted herself to the experimental work, from which Marie Curie regained her self-confidence.

At the end of 1902, Marie Curie extracted 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 difficult to obtain natural radioactive substance, its shape is shiny, white crystals like fine salt, radium has a slightly blue fluorescence, and it is this beautiful light blue fluorescence, integrated into a woman's beautiful life and unyielding faith.

The discovery of radium has fundamentally changed the basic principles of physics, and is of great significance for promoting the development and application of scientific theories in practice.

Listening to Professor Chen Qi's brief recount, Marie Curie is a famous French Polish scientist, physicist, and chemist, who has won many medals and honors in her life, and she has to admire this female scientist when she looks at these honors.

Qu Lihua nodded, "I heard the story of Marie Curie in textbooks when I was in school, I came to Poland and saw Marie Curie's museum, which exhibited some of the things she used during her lifetime, and listened to Professor Chen talk about the life and deeds of this female scientist, and also deeply admired this female scientist, it is indeed not easy to achieve such outstanding achievements in the male-dominated scientific community." ”

Meng Wenjie said: "As a female scientist, you have to be in the laboratory all day long, do scientific research, do it for a long time, do chemical experiments, and understand chemical knowledge, behind those honors, is the hard work every day, all isotopes of radium are highly radioactive, radium is highly toxic, it can replace calcium in the human body and concentrate in the bones, chronic poisoning can cause osteoma and leukemia, Marie Curie eventually died of leukemia." ”

Head Xia Yuxiang was very emotional, "If a person wants to achieve achievements in a certain field, he also has to pay a lot, Marie Curie has been doing experiments in the laboratory all the year round, spending a lot of time and energy, and while contributing to mankind, her physical health has also suffered, and after a long time, she was exposed to these radioactive chemical elements and died of leukemia." ”

Marie Curie became a famous female scientist, won many honors, sacrificed her health, and dedicated her life, Marie Curie advocated the use of radiology to treat the wounded, and promoted the application of radiology in the field of medicine. ”

"In the 90s of the 20th century, Marie Curie's portrait appeared on Polish and French currencies and stamps, and people used this way to commemorate the Curies. ”

Qu Lihua and Meng Wenjie stood in front of the old photos of the Curie couple kept in the Marie Curie Museum, and they were very emotional.

"Xiaoqu, what do you feel? Tell everyone about it!" said Head Xia Yuxiang.

Qu Lihua said: "Looking at the old photos of the Curie couple, I am also very emotional, I think Marie Curie is lucky and unlucky!"

Fortunately, she was born in a family of Polish intellectuals, her parents were intellectuals, she was able to receive a good education from an early age, and also laid the foundation for her future research work, fortunately she met her husband, the two were like-minded, both had the same dream, when the husband was alive, the two studied together and did experiments, this may be the happiest time in Marie Curie's life, the two also gave birth to two daughters, and had the crystallization of love. ”

It's a pity that this happiness is very short-lived, an accident changed the fate of Marie Curie, middle-aged widowed, with emotional lack and pain, and Paul Langevin after meeting, it is emotional entanglements, scandals and detours, which gave Marie Curie a heavy blow, no matter how strong a woman is, she needs the company of her male partner, her husband died unexpectedly, the lack of affection, and it is inevitable to have feelings with other men at work. ”

Unfortunately, Paul Langevin was a married man who already had a wife and a daughter, and a period of pain also brought Marie Curie's life into a storm, accusations and abuses were endless, and Einstein's opinion on this matter was that if they loved each other, no one could care, and he wrote a letter to Marie Curie on November 23, 1911, to express his comfort. ”

"Einstein was so open-minded, he could give encouragement and support to Marie Curie, and it was also the motivation to re-energize Marie Curie, a person needs the encouragement and support of friends when he is vulnerable, and he also needs to learn from this incident to avoid hurting himself!"
