WORLD HISTORY

Detailed explanation-1: -Curie was a pioneer in researching radioactivity, winning the Nobel Prize in Physics in 1903 and Chemistry in 1911. Curie never worked on the Manhattan Project, but her contributions to the study of radium and radiation were instrumental to the future development of the atomic bomb.

Detailed explanation-2: -She suggested that the powerful rays, or energy, the polonium and radium gave off were actually particles from tiny atoms that were disintegrating inside the elements. Marie’s findings contradicted the widely held belief that atoms were solid and unchanging.

Detailed explanation-3: -In 1898 French physicists Pierre and Marie Curie discovered the strongly radioactive elements polonium and radium, which occur naturally in uranium minerals. Marie coined the term radioactivity for the spontaneous emission of ionizing, penetrating rays by certain atoms.
