Madame Curie shared the purification method of radium: Madame Curie could have applied for a patent after discovering radium, thus obtaining a large fortune. However, she did not do this, but did not hesitate to make the purification method of radium public. Later, Madame Curie was unable to engage in scientific research because she had no funds to buy 1 gram radium. Finally, a well-known American female journalist launched a fund-raising campaign in the United States, raising the required $654.38 million+.
3. The United States in the financial crisis: In today's financial crisis, the post-war economic system established by the United States after World War II is centered on the US dollar. Although the United States has experienced a crisis, it has developed rapidly and it is difficult for small and weak countries to get rid of it. Although the financial crisis was caused by various factors, the United States did not know how to share economic benefits with the vast number of countries, even if it was a small part, which led to the extreme expansion of its economy, the extreme concentration of interests, the extreme concentration of crises, and the loss of the American economy. Our country, on the other hand, has always adhered to the ancient road, been kind to others, extended a helping hand again and again, and has not been too involved in this crisis. Although it is due to the proper measures taken by the government, there are some shared achievements, even ordinary achievements.
