Stuart Firestein has an interesting take on science and teaching science. He means that we should teach what we do not know yet instead of just consentrating on teaching what we do know. We should teach which are some of the questions that still needs answering. He quotes George Bernard Shaw (1856-1950):
“Science is always wrong. It never solves a problem without creating 10 more”
What we do not know makes a good question. Also, he means that the longer into the PhD program one gets the better questions one is able to ask.
