Inspired by the Illustration Friday quote:
"A good scientist is a person in whom the childhood quality of perennial curiosity lingers on. Once he gets an answer, he has other questions". - Frederick Seitz
Childhood curiosity leads us with a string of questions into unexplored territory. Finding one answer, the mind is already wondering about the next question. And the next. And the next. Observations shed in the quest for a particular answer surface later for further exploration.
