[The piston of the steam engine could accomplish work.

What type of work?

‘Work’ has a technical definition in physics. Here, I mean ‘getting a task accomplished’ in contrast to ‘wasting effort’.

This goes with the perspective level of a steam engine.

The perspective level of the piston may interscope with higher nested forms.

The result is another interscope.]
