How many questions do we ask each day? Why do we ask them in the first place? Do we always ask because we're trying to learn something? Or are there some questions we don't expect to have answered - and some questions that simply can't be answered at all? What do our questions tell us about ourselves? Do they define who we are? Who asked the world's first question? Can anyone answer all these questions? Is that a stupid question, or is it a really good one? And what does Pia Lauritzen, Aarhus University's questioner-in-chief, think of all of this?.
