The importance of questions

Here's an important story:

When Isido Rabi, the 1944 Nobel Prize winner in physics, was interviewed about his achievements, he said he owed it all to his mother. "When we got out of school, all the mothers would ask their children what they had learned that day. My mother would inquire instead, 'What did you ask today in class?' "

— Rabbi Nilton Bonder

What a very wise woman indeed.
