 Hi there, you're back with me, Noah, for this week's Unexpected Elements quiz. Talking of weddings reminds me of all those famous couples that have worked together under the banner of science, like the infamous Marie and Pierre Curie. They shared lots of firsts together, not just first kisses and first dates, but incredible feats in science too, like the discovery of the elements polonium and radium. And of course, they even discovered radioactivity itself.
