Step close to a patterned surface and its individual marks become distinct. Step back and a larger arrangement takes their place. Neither view is complete, but each makes a different kind of question possible.
The question sets the distance
When studying a complex subject, it helps to name the scale of interest. Are we asking about the behaviour of one part, the connection between parts, or the pattern of the whole?
Once the question is clear, the choice of observation becomes easier to explain. A detailed view may reveal a mechanism. A wider view may reveal whether that mechanism is enough to account for the larger behaviour.
Notice what changes in the translation
Moving from one scale to another often involves simplification. Individual differences may be grouped together, and local relationships may be replaced with an average description.
Those choices can be useful. They should also remain visible, especially when a conclusion is being carried into a different setting. A result at one scale is a starting point for the next question.
Keep more than one view
Working between detail and context is a practice of comparison. Describe where the views agree, where they differ, and what each leaves unresolved.
A change of scale can change the story. Keeping the question in sight helps us decide whether it has made the story clearer.
