In July 1898, Marie Sklodowska Curie and Pierre Curie published work where they mentioned the term radioactivity for the first time. During that same year, the two Nobel Prize laureates discovered two new elements: polonium (in June 1898) and radium (in December 1898). Watch the story behind the discovery of polonium, as well as radium. #NobelPrize | Nobel Prize

Radium was used up until the 1950s on watches for its luminous properties, but it turns out it's a fairly dangerous substance. Extra precautions must be taken when working on one of these watches, and some people just prefer not to all together. #watches #watchmaking #watchrepair | Wristwatch Revival
