The discovery of radium has caused great changes in science and even philosophy, and opened the door for human beings to explore the mysteries of the atomic world. It can be said that its discovery has opened up a new field of science, from which a new radiology was born. Therefore, radium is known as a "great revolutionary".
It is precisely because the Curies made great contributions to the scientific revolution that they won the Nobel Prize in Physics the following year.
Soon after, people discovered the value of radium in medicine and brought good news to cancer patients, which made the already expensive radium more precious. Someone advised the Curies to say, "If you apply for a patent, you will definitely become a millionaire!"
"No, radium is an element, it should belong to the whole world!" The curies did not hesitate to answer.
The Curies believed in "science knows no borders". It can also be said that this is their common ambition to devote themselves to science. Unfortunately, one day in April of 1906, pierre curie lost his precious life in a car accident. Madame Curie fought back her grief and continued her scientific research. 19 10, Madame Curie successfully separated pure radium, analyzed its various properties, and accurately determined its atomic weight. In the same year, at the International Radiology Council attended by Madame Curie, the radioactive unit named after Madame Curie was formulated and the international standard of radium proposed by Madame Curie was adopted.
1920 In May, an American female journalist visited Madame Curie and asked, "If you could choose everything in the world, what would you prefer?" "I really want to have a gram of pure radium for research. But its price is too high, I really can't afford it. " Madame Curie replied.
"Didn't you send radium worth millions of francs to the laboratory of Paris University?" The female reporter asked inexplicably.
"No, that's not mine. It belongs to the laboratory. "
Hearing this, the reporter was deeply moved by the selfless spirit of the female scientist who devoted herself to science. After she returned to the United States, she wrote many articles about the Curie couple, calling on the American people to carry out donation activities and give Madame Curie a gram of radium. In May of the following year, the President of the United States personally gave this gram of radium to Madame Curie in Washington. ..
On the eve of the gift ceremony, Madame Curie insisted on revising the words on the gift certificate, and once again declared: "This gram of radium given to me by the United States should always belong to science and cannot be my personal private property."
This great woman won two Nobel Prizes in her life. She is the first female professor at the University of Paris and the first female academician of the French Academy of Sciences. At the same time, she was also hired as an academician of other 15 countries. She won 24 awards and medals from 7 countries and held 104 honorary positions in 25 countries. 1On July 4th, 934, this great scientist passed away, but her spirit will inspire future generations forever!
