Marie was a kid who liked questions.
She wanted to know why water is wet, why the moon stays in the sky, and why the metal in her father's lab made the air feel warm.
Most grown-ups told her, 'Don't worry about that.' Marie kept asking anyway.
She learned to write down what she saw, take careful measurements, and try things twice to be sure.
When she grew up, she discovered something nobody had ever seen — and she did it by sticking with her questions.
