Asking questions is in fact what scientists do to start the process of examination!
But....there's more - much more
The detailed work - the math, the experiments, the testing and retesting, the laborious detail* -that is
the real work of the scientist. Finding answers, then subjecting them to tests designed to break them*.
Documenting, writing up (grading papers in there sometimes too). It might take a career's worth of
work to answer one question. Maybe more than one career.
*All of which are made possible by ongoing decades of study to understand and master his craft. Reading
a dozen to two popular level science adaptations doesn't get it there. Insisting that math is just details
doesn't either. Sound elitist?
**One of the more obvious differences between a real scientist and someone else is seen in this forum
all the time - people asking others to agree with them are not scientists. People asking what they have
missed, showing their work rather than tossing word salads, asking why something might be wrong, they
are looking for the truth. There's your scientist. He understands you never get closer to the truth by
having someone agree with them - the folks that tell them they are wrong are either right, or in their
wrongness teach them something new about their own ideas.
