In order to extract radium from a ton of industrial waste residue, Madame Curie had to boil the waste residue pot by pot and keep stirring. Bottles come in and out, little by little crystallization.

In summer, the hot warehouse is filled with thick smoke, her work clothes are stained with dust and sweat, and her eyes and throat are stung by smoke, but she still insists on refining minerals; In the cold winter, it is necessary to open the window at any time to prevent gas exhaustion from causing poisoning, so she is often too cold to take notes with a pen. In such a bad working environment, Madame Curie insisted on studying.

She stood by the cauldron in her work clothes covered with dust and acid every day, with smoke, tears in her eyes and itchy throat ... In this way, she struggled for 35 years and extracted 0. 1g radium from tons of slag.

Brief introduction of Madame Curie:

He received his degree in Paris and engaged in scientific research. He was the founder of the Curie Institute in Paris and Warsaw.

1903, the Curies and becquerel won the Nobel Prize in physics for their research on radioactivity.1910/year, Madame Curie won the Nobel Prize in chemistry for her discovery of polonium and radium, becoming the first person in history to win two Nobel Prizes. Marie Curie's achievements include creating the theory of radioactivity, inventing the technology of separating radioactive isotopes, and discovering two new elements, polonium and radium, in February 2 18+0.

Under her guidance, people used radioisotopes to treat cancer for the first time. Madame Curie was a pioneer of successful women, and her example inspired many people. Pierre curie, her husband, died on the spot after being knocked down by a carriage on a rainy day in April 1906, while Madame Curie died of malignant leukemia on July 3 1934 due to long-term exposure to radioactive substances.
