Happy Birthday, Marie Curie!
Well, not "happy birthday" so much as "let's celebrate the 149th anniversary of the birth of Marie Curie." Or as we like to call her, Maria Salomea Skłodowska-Curie. She was the first woman to win a Nobel Prize, discovered two elements, and was a pioneer in radioactive research. Without her, who knows if radioactive spiders would've been around to bite our favorite Spidey-sense tingling hero!?
