In schools, science is often taught as a body of knowledge — a set of facts and equations. But all that is just a consequence of scientific activity.
Science itself is something else, something both more profound and less tangible. It is an attitude, a stance towards measuring, evaluating and describing the world that is based on skepticism, investigation and evidence. The hallmark is curiosity; the aim, to see the world as it is. This is not an attitude restricted to scientists, but it is, I think, more common among them. And it is not something taught so much as acquired during a training in research or by keeping company with scientists.
This is why I proposed the revamping of the intro physics labs, with the aim towards the students that are NOT physics/science majors. It is one of the few classes they will have where they can acquire such skill that a scientist must have.
