I call it fairy tale because science is a never-ending story. At the beginning of any scientific work, there is always a question. Often this question is related to a problem of every day life. In former days scientists solved a lot of difficult problems, like diseases. During the years our life standard increased, because of the interventions scientists made in the past. Another motivation for science is often a discovery. Something interesting we observed, for example, in the nature. We are curious about it and want to find an explanation for it. Scientific work is a puzzle of assumptions, imagination, inference and vision. It happens that someone disproves a hypothesis and shows that the insight the first scientist had was wrong. This is also a part of science; to learn to live with disappointments. A scientist should never give up and should be able to try experiments again and again. From this it is becomes clear that science is a never-ending fairy tale.
