Marie Curie

(Marie Curie) is a French scientist originally from Poland. She and her husband Pierre Curie were early researchers of radioactivity. They discovered the radioactive elements polonium (Po) and radium (Ra), and therefore shared the 1903 Nobel Prize with French physicist Henri Becquerel. Bell Prize in Physics. After that, Marie Curie continued to study the application of radium in chemistry and medicine, and won the 1911 Nobel Prize in Chemistry for isolating pure metallic radium.

Marie Curie lived in poverty for most of her life, and the arduous process of extracting radium was completed under crude conditions. The Curies refused to patent any of their discoveries in order to allow everyone to freely exploit their discoveries. They used the Nobel Prize and other bonuses for future research. One of the outstanding applications of their research work is the use of radioactivity to treat cancer.

Bacon said, "Beauty is like fruit in midsummer, which is easy to rot and difficult to maintain." But why does the author think that Madame Curie's beauty can span a hundred years?

Expressions of inner beauty:

(1) Rigorous scholarship and active exploration

Others picked up a shell on the beach, but she wanted to study how the shell was born, how it grew, and how it washed up on the beach. When others touched melons, she looked for vines, and when others picked leaves, she asked about the roots.

(2) Hard work

The laboratory was just an abandoned shed. Mary stirred the slag in the pot all day long amid the smoke and fire. There were little burn marks of acid and alkali on her dress and hands.

(3) Selfless and persistent

Marie Curie obtained a ton of industrial waste that may contain radium. They set up a pot in the yard and smelted it pot by pot, and then sent it to the laboratory for dissolution, precipitation, and analysis.

(4) Persistence

Finally, after three years and nine months, they extracted 0.1 grams of radium from tons of slag.

Complete this exercise based on the meaning of this sentence:

She changed from a beautiful little girl, a dignified and resolute female scholar, to a new term "radiation" in science textbooks, to a new measurement unit "Curie" in physics, and to scientific laws. It has become an eternal milestone in the history of science.
