On this day, 127 years ago, on December 26, 1898 (November 14, 1898, the lunar calendar), Madame Curie discovered radium. On December 26, 1898, Marie Curie announced in a report submitted to the French Academy of Sciences that they had discovered another new element, radium, that was millions of times more radioactive than uranium. It was the result of the great love that Pierre Curie and his wife Marie Sklodovska had been married for three years. The discovery turned the entire theory that had been believed in in the field of physics for centuries at the time. Some conservative scientists have expressed doubts,"Where is radium?" Show it to us and we can believe it!" Pierre and Mary were determined to answer all these doubts with facts. However, to extract pure radium, a large number of minerals and a large laboratory are necessary. Pitchblende was the most expensive mineral, and they could not afford it. Later, with the help of a professor in Austria, they spent all their savings and sold all valuable things before buying more than a dozen sacks of pitchblende slag. For the sake of the laboratory, the Curies negotiated with the University of Paris and responded with ruthless ridicule. Finally, the physics and chemistry school agreed to provide them with a wooden shed that they would not use for a long time. The floor of the wooden shed is paved with asphalt, and the glass roof is so dilapidated that it cannot withstand the wind and rain. There were only two dilapidated tables in the room, a stove and a small blackboard that Pierre used to make calculations. It was in such a dilapidated house that the Curies began their great scientific experiments. The sun and the moon are like flowing water. The Curies seem to be in a dream, forgetting time. Regardless of winter or midsummer, they work nervously all day long, regardless of night and day. Due to too little sleep and too much physical exertion, their health is compromised. Pierre was in pain all over, and Mary was obviously thin, but they persisted. After 45 months of labor and tens of thousands of refinements, they finally succeeded in obtaining 10 grams of pure radium. Radium was discovered, and it was soon discovered that radium had the effect of treating cancer. The price of radium soared. Some friends advised the Curies and his wife to apply for a patent. With this patent right, the Curies and his wife would become rich in the world in an instant. But Pierre said: "No! We should not make money from new atoms discovered. Radium is a kind substance that saves people, and it should belong to the world. Pierre Curie was born on May 15, 1859 in Paris, France. His father is a doctor. Pierre and his brother's initial education was conducted at home. Their parents adopted a relatively free education method. In addition to arranging the prescribed study plan, they also encouraged them to read more extracurricular reading materials and have more contact with nature. Develop their ability to observe things during outings. Pierre received a bachelor's degree in science from the Faculty of Arts and Sciences of the University of Paris at the age of 16 and a master's degree in physics at the age of 18. He stayed there as a laboratory assistant. In 1883, Pierre became director of the Physics Laboratory of the Paris Municipal School of Physics and Chemistry. Marie Curie is a French Polish citizen. She was born on November 7, 1867 in an intellectual family in Warsaw, Poland. Her original name was Marie Skrodowska. Her father was a graduate of St. Petersburg University and later taught mathematics and physics in a middle school in Warsaw. In 1891, Mary bid farewell to her family and was admitted to the School of Science at the University of Paris, where she began her further studies. In 1893, she graduated from the Department of Physics at the University of Paris, ranking first in the class and obtaining a master's degree in physics. The following year, she graduated from the Department of Mathematics, ranking second in the class, and obtained a master's degree in Mathematics. After graduation, Mary wanted to return to Poland to work. However, because she met the young French physicist Pierre Curie, she stayed in France after getting married. In 1903, the Curies won the Nobel Prize in Physics for the discovery of radioactive elements.
