There is a story of Isidore Rabi (1898), Nobel-prize winner
for physics, and how his mother would always ask him,
when he got home from school:
‘Izzy, did you ask a good question today?’ Every other child
would come back from school and be asked,
‘What did you learn today?’
But his mother stimulated him to be a question-asker.
Without even knowing it, Isidore explains later, his mother
made him into a scientist
(after Sachs 2012).
