In 1978, Ling’s best friend shared a biography of Marie Curie with her. Science intrigued the two girls. But most of all, Marie Curie’s story helped them realize that women can be scientists too. "We both found science so interesting and meaningful," says Ling. "We dreamed of becoming scientists whose discoveries could help people."
