When you first read the text, think about what the text is about?

The text tells the story of the discoverer of radium, Madame Curie, who owned three grams of radium.

About "Radium"

Radium radioactive element. Silvery white crystal, its luster is extremely radioactive and can continuously release a large amount of heat. Radium's radiation has strong penetrating power, can destroy animal tissues and kill bacteria, and can be used to treat cancer and skin diseases.

The title of the text is "Marie Curie's Three Grams of Radium". Which three grams of radium do these three grams of radium refer to?

The first gram of radium - extracted by Madame Curie

Second gram of radium—donated by the U.S. public—for research

The third gram of radium—a donation from the American public—founded the Radium Institute

Marie Curie’s explanation was unusually plain: “No one should get rich from radium, it belongs to all mankind.”

"Exceptionally plain" means that Marie Curie thought it was normal for them to do this and didn't think it was such a great thing. It is a very extraordinary act to publish one's major scientific research results to the public without reservation. But Madame Curie herself saw it as "exceptionally plain", which shows how lofty her ideological realm was. "No one should get rich from radium" shows that Marie Curie does not use her scientific research results as capital for profit, and believes that others should not do the same. It is a pity that not everyone is as selfless as the Curies. As the text says, "the purification technology of radium made businessmen all over the world rich", which completely went against the original intentions of the Curies.

Read the text again and discuss: Why is it said that "these three grams of radium show the great personality of a scientist"?

From the story of three grams of radium, we can see that Madame Curie was a scientist with a very noble character but a very difficult material life. Her ideological realm is so lofty. When she and her husband extracted the first gram of radium, they believed that this scientific research result should "belong to all mankind", and then "unreservedly announced the radium "purification method" without considering that this is a great opportunity for them to obtain huge wealth. According to an American reporter's inference based on the price of radium at the time, Marie Curie had already become rich thanks to this patent alone. However, Marie Curie did not seek personal interests, so that her material life fell into a difficult state. His laboratory was quite simple and he could not even afford one gram of radium needed for experiments. He had to rely on donations from the public. Therefore, from the story of these three grams of radium, we can see what a noble personality this scientist has.

Madame Curie's famous sayings

The weak wait for opportunities, while the strong create opportunities.

I want to turn life into a scientific dream, and then turn the dream into reality.

We should not waste our lives and should be able to say: "I have done what I can do."

On the road to fame, what is shed is not sweat but blood, and their names are written not with a pen but with their lives.
