1898 65438+On February 26th, Mary announced in a report to the French Academy of Sciences that they had discovered a new element-radium, which is one million times more radioactive than uranium. This is the crystallization of great love between pierre curie and his wife Mary Sklodowska after three years of marriage.
This discovery subverts the whole theory that physics has been believing for centuries. Some conservative scientists expressed doubts: "where is radium?" Show us and let us believe! " Pierre and Mary are determined to answer all these questions with facts. However, to extract pure radium, there must be a large number of minerals and a large laboratory. Pitch uranium ore is one of the most expensive minerals, and they can't afford it. Later, with the help of an Austrian professor, they spent all their savings and sold everything of value before buying more than a dozen sacks of pitchblende slag. For the laboratory, the Curies negotiated with the University of Paris and answered them with merciless ridicule. Finally, the school of physics and chemistry agreed to provide them with a wooden shed that had been useless for a long time. The ground of the wooden shed is paved with asphalt, and the glass roof is worn out. There are only two worn-out tables, a stove and a small blackboard that Pierre used to calculate. It was in this shabby house that the Curies began their great scientific experiment.
The sun and the moon are flowing, and the Curies seem to be in a dream and forget the time. Whether it is winter or summer, night or day, they work nervously all day. Because of too little sleep and too much physical exertion, their health is damaged. Pierre was aching all over, and Mary obviously lost weight. However, they persisted. After 45 months of labor and tens of thousands of refinements, they finally succeeded in obtaining10g 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 suggested that the curies apply for a patent. With this patent right, the Curies will soon become the richest people in the world. But Pierre said, "No! We shouldn't make money from the discovery of new atoms. Since radium is a good substance to help the world and save mankind, it should belong to the world. "
Pierre curie was born in Paris on1May 1989 1859. His father is a doctor. Pierre and his brother's enlightenment education was carried out at home. Their parents adopted a relatively free education method. In addition to arranging the prescribed study plan, they also encourage them to read more extracurricular books, get in touch with nature and cultivate their observation ability for outings. Pierre received a bachelor of science degree from the College of Arts and Sciences of Paris University at the age of 65,438+06, and a master's degree in physics at the age of 65,438+08, and stayed as a laboratory assistant. From 65438 to 0883, Pierre was the director of the physics laboratory of Paris Municipal School of Physics and Chemistry.
Marie Curie was born on1867165438+1October 7th in an intellectual family in Warsaw, Poland. Her original name was Mary Tusk Rodovska. Her father graduated from St. Petersburg University and later taught mathematics and physics in a middle school in Warsaw. 189 1 year, Mary left her family and was admitted to the Faculty of Science of Paris University, where she began her further studies. 1893 graduated from the physics department of Paris University, 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 her class and obtaining a master's degree in mathematics. After graduation, Mary wants to work in Poland. However, because she met pierre curie, a young French physicist, she stayed in France after getting married.
1903, the curies won the nobel prize in physics for discovering radioactive elements.
