What is three grams of radium?

Question 1: What is three grams of radium? Uncle's correct message is this: Madame Curie had three grams of radium in her life. She donated the first gram to him to do science, and the public returned the second and third grams to her. These three grams of radium show the great personality of a scientist and the public's understanding of science. 1920 One morning in May, an American journalist named Mrs. maloney finally met the discoverer of radium in the Paris laboratory after many twists and turns. The dignified and elegant host and extremely simple laboratory left a deep impression on the American reporter. To Madame Curie's great surprise, she was able to tell the location of every scattered radium in the world. Mrs. maloney asked, "How many are there in France?" "My lab has only one gram." "Do you only have one gram of radium?" "Me? Oh, I didn't. This gram belongs to my laboratory. " At this time, radium has been 18 years, and its original value is as high as 750,000 gold francs. American female journalists concluded that the patented technology of purifying radium should make this lady rich in the world. But in fact, the Curies gave up their rights as early as 18 years ago and published the purification method of radium without reservation. At that time, they were financially strapped and lived in poverty, but they refused to use their hard-earned scientific achievements to obtain any personal interests. Madame Curie later explained that it was plain: "No one should get rich from radium, it belongs to all mankind." Mrs. Malone was puzzled and asked, "Is there nothing you want most in this world?" "Yes, one gram of radium is available for my research, but I can't afford it. Too expensive. " This unexpected answer made Mrs. Malone both surprised and very uneasy. The purification technology of radium has made businessmen all over the world rich, but the discoverer of radium is stuck and can't be studied at all! She immediately flew back to the United States and found that the market price of one gram of radium in the United States was $6,543,800. She first found 654.38+00 female millionaires, thinking that they were all women and rich, and they would definitely take out their money to help, but they ran into a wall. This made Mrs. Malone realize that this is not just a demand for money, but a social education that calls on the public to understand science and carry forward the character of scientists. She ran around among American women and achieved success. 1921On May 20th, American President Harding presented a gram of radium donated by the people to Madame Curie. After reading the document carefully, Madame Curie said, "This gram of radium given to me by the United States should always belong to science. I hope you can hire a lawyer immediately and hand it over to my laboratory. " A few years later, when Madame Curie founded a radium research institute for herself to treat cancer in Warsaw, Poland, the American people donated a second gram of radium to her again. Some people think that Madame Curie's stubbornness in dealing with radium is incomprehensible. Since it is for scientific research, wouldn't it be much easier to sign the patent book? Madame Curie answered this question in her later autobiography: "... many of my friends insisted that if Buel? Curie and I have reserved my rights, so that we can get the necessary funds to establish a satisfactory radium research institute, and all the difficulties that hindered us in the past and still hinder me can be avoided. What they said is not unreasonable, but I still believe that we are right. Humans need people who are good at practice. They can get great gains from their work. They can not forget the public welfare, but also protect their own interests. But human beings also need dreamers, who are obsessed with the selfless development of a cause and therefore cannot pay attention to their material interests. " Even for the sake of science, you can't take scientific achievements for yourself. This is another value that Madame Curie contributed to mankind while contributing radium.

Madame Curie's three grams of radium, the first gram was extracted by herself; The second is Mrs. maloney, an American journalist, who runs around among American women for promotion and is donated to her by the American public. The third gram of radium was also donated by the American public. Madame Curie, as the discoverer of radium, was not only not as rich as the American journalists inferred, but also so poor. It is precisely because Madame Curie did not take the patent right of radium for herself, but dedicated it to all mankind. A passage in Madame Curie's autobiography is difficult to understand. She said, "Human beings need people who are brave in practice. They can get great gains from their work, not forgetting the public welfare, but also safeguarding their own interests. However, human beings also need dreamers and selflessness, which shows two attitudes towards life: one is not forgetting the welfare of the public, but also safeguarding their own interests; One is a selfless idealist who is obsessed with his career. Both kinds of people are beneficial to society. Madame Curie also affirmed the former. But Madame Curie obviously belongs to the latter. She has contributed everything to science and all mankind. Patent right is the right granted by the state to the inventor to exclusively exploit his invention and creation. When the Curies extracted the first gram of radium, they announced the purification method of radium without reservation and gave up the patent. Even if the American public donated two grams of radium to her, one gram for scientific research and one gram for establishing a radium research institute for the motherland, it would have no effect on her.
