Two Prizes, One Question
How did Marie Curie win two Nobel Prizes in two different sciences?

Two Nobel Prizes. Two different sciences. One person. It sounds like a typo, but it isn't — Marie Curie really did it, and she's still the only person ever to win Nobels in two separate sciences. So how do you pull off a trick like that? You start by being curious about something invisible.
In the 1890s, a strange discovery was in the air. Certain rocks seemed to give off invisible rays all by themselves — no fire, no sunlight, no battery. Nobody knew where the energy came from. Most scientists shrugged and moved on. Marie did the opposite. She decided that the mystery was her whole job.
