Summary

Every science begins with empiricism, with precise observation and measurement, with an investigation of reality, and with the verification of the results obtained. This is followed by an open-minded and questioning search for patterns, for structures and recurring results. Subsequently, attempts can be made to develop hypotheses, theories, and models, to test them, to discuss and criticize them, to question them, to further develop them or to discard them in favor of better and more accurate measurement methods and hypotheses, theories, and models. This is a truism and a matter of course, to which every scientist of all other disciplines would respond with nothing more than a shrugging nod.
