“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 was born on this day in 1867. As a physicist and chemist she did pioneering work on radioactivity and was the first woman to win a Nobel prize. She coined the term ‘radioactivity’ and discovered the elements polonium and radium. She died in 1934 of a rare disease that may be been caused by her prolonged exposures to radioactivity without safety measures. Even today her possessions and papers are too radioactive to handle without protection.
