" Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less. "
Marie Curie lived from the year 1867 to 1934. She is a French physicist, and is very famous for her work in the study of radioactivity. She won the 1903 Nobel Prize in Physics for her contributions to the field of physics and knowledge of radioactivity.



When she discovered two highly radioactive elements, “Radium” and “Polonium", she started her work on the **Theory of Radioactivity**.

In 1895, physicist Wilhelm Roentgen discovered a kind of ray that could travel through wood or flesh and produce photographs of people's bones. In 1896, after Roentgen's discovery, French physicist Henri Becquerel found out that uranium compounds, even when kept in the dark, emitted rays that can fog a photographic plate.

Scientists neglected Becquerel's finding, instead focusing on Roentgen's "X-rays", until Marie Curie did experiments to prove that electrical effects of uranium rays are constant, regardless of whether the uranium was solid or liquid. Likewise, her studies proved that minerals with a higher proportion of uranium emitted the most intense rays. She then formed a hypothesis: **"The emission of rays by uranium compounds could be an atomic property of the element uranium."**

This video goes through the achievements that Marie Curie has made for the field of physics and radioactivity, helping to make the world we know safer from the radioactivity that some might be exposed to. media type="youtube" key="0vTRrZU-LKQ?fs=1" height="385" width="640"
