"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
Marie Curie had one of the greatest scientific minds in history. She was the first woman ever to win a Nobel Prize in Physics, and she later won another for her work in Chemistry, which made her be the first to win a Nobel Prize twice. With her husband, she helped discover polonium and radium. She also helped further improve x-rays.
