As in the title. I know she was working with radioactive atoms and she made huge progress in the field of physics. But where would you find the application of her discoveries in our world? Is it just used in theoretical physics or does it have any meaning to us mortals?
Marie Curie helped to understand the nature of radioactivity, which evidently has subtantial concrete consequences in the production of nuclear energy for instance, but also in the medical applications like X-ray radiography. She was a pioneer in the treatment of cancer using radioactivity.
