The weak sit and wait for their opportunity; the strong create their opportunities. This is Madame Curie's famous saying.

Marie Curie (November 7, 1867 - July 4, 1934), born in Warsaw, known as "Madame Curie", full name Maria Sk?odow Maria Sk?odowska Curie, a famous French Polish scientist, physicist, and chemist.

In 1903, the Curies and Becquerel won the Nobel Prize in Physics together for their research on radioactivity. In 1911, they won the Nobel Prize in Chemistry again for the discovery of the elements polonium and radium. Thus becoming the first person in the world to win two Nobel Prizes. Marie Curie's achievements include pioneering the theory of radioactivity, inventing technology for separating radioactive isotopes, and discovering two new elements, polonium and radium.

Scientific achievements of Madame Curie

In experimental research, Madame Curie designed a measuring instrument that can not only measure certain Whether there are rays in a substance, and the intensity of the rays can be measured. After repeated experiments, she found that the intensity of uranium rays is proportional to the amount of uranium in the material, and has nothing to do with the state of uranium existence and external conditions.

Madame Curie conducted a comprehensive examination of known chemical elements and all compounds, and made an important discovery: an element called thorium can also automatically emit invisible rays. It shows that the phenomenon that elements can emit rays is not just a characteristic of uranium, but a unique characteristic of some elements.

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