Outline of Madame Curie

The book Biography of Madame Curie reviews the extraordinary life of Madame Curie, a great woman who influenced the world process, and mainly describes Madame Curie's quality, work spirit and attitude towards things.

The author tells readers in detail that her mother has not only made outstanding achievements in the field of science, but also set an example for her daughter with her noble behavior of interacting with others all her life. She also has many unique methods to educate her daughter.

Extended information Marie Curie, a famous Polish scientist, physicist and chemist in France. 1903 Mr. and Mrs. Curie and becquerel won the Nobel Prize in physics for their research on radioactivity.191kloc-0/won the Nobel Prize in chemistry again in, becoming the first person in the world to win the Nobel Prize twice.

Madame Curie's achievements include initiating the theory of radioactivity, inventing the technology of separating radioactive isotopes, and discovering two new elements: polonium and radium. Under her guidance, people used radioisotopes to treat cancer for the first time. Due to long-term exposure to radioactive substances, Madame Curie died of malignant leukemia on July 3, 1934. ?

In the experimental research, Madame Curie designed a measuring instrument, which can not only measure whether a substance has radiation, but also measure the intensity of radiation. After repeated experiments, she found that the intensity of uranium rays is directly proportional to the uranium content in the material, but has nothing to do with the existing state of uranium and external conditions.

Madame Curie made a comprehensive investigation of known chemical elements and all compounds, and made an important discovery: an element called thorium can automatically emit invisible rays, which shows that the phenomenon that an element can emit rays is not only the characteristics of uranium, but also the same characteristics of some elements.

She called this phenomenon radioactivity, and called elements with this property radioactive elements. The radiation they emit is called "radiation".

At the end of 1902, Madame Curie extracted one tenth of extremely pure radium chloride and accurately determined its atomic weight. Since then, the existence of radium has been confirmed.

Radium is a natural radioactive substance, which is extremely difficult to obtain. Its shape is shiny white crystal like fine salt. Radium has a slight blue fluorescence, and it is this beautiful light blue fluorescence that blends into a woman's beautiful life and unyielding faith.

In spectral analysis, it is different from the spectral line of any known element. Radium is not the first radioactive element discovered by human beings, but it is the most radioactive element.
