It might also be representing the Laplace Transform, where you convert equations from time-based space to frequency-based space. I used it a bunch in engineering school to make super complicated differential equation relationships into simpler terms.
As a specific example: it is used in control loops to accurately describe your system. If you have an accurate description it then becomes trivial to describe the PID controller to manage it. Going from open to closed loop is as simple as adding +1 to your equation for example.

Shit is pretty cool…
