“I wish that our current educational approaches put much more emphasis on following one’s curiosity and asking ‘Why?’, rather than on memorization of facts and rote reproduction of processes. We can hardly blame students for not being curious when our educational system doesn’t generally reward that. So, sadly, it is surprising when a student asks ‘Why?'”

If you’ve not already, you should read the book “A More Beautiful Question” by Warren Berger. http://amorebeautifulquestion.com/ I don’t get anything for plugging his book, other than the simple satisfaction of changing the world one mind at a time.
