Perturbation implies an interruption that's usually surprising or unplanned.

Unexpected Disruption

When perturbation happens, it can lead to people being confused or disorganized.

Confusion Trigger

Emotional perturbation refers to an internal state of worry or upheaval.

Internal Anxiety

Perturbation may imply a lower level of distress compared to words like 'panic' or 'terror'.

Less Intense

In physics, perturbation is about small, measurable changes, not general confusion.

Physics Specific

A perturbation in a physical system is something that can be observed and quantified.

Quantifiable Change

In mathematics, perturbation is a tool to understand complex systems through approximate solutions.

Theoretical Tool

Mathematical perturbation often involves a 'gentle touch' to see what happens.

Gentle Disturbance

 I was expecting the robot to immediately fall over, because there are no sensors, no fast feedback loop. But no, just the mechanics stabilized the gait, and the robot doesn't fall over. Obviously, if you make the step bigger, and if you have obstacles, you need the full control loops and reflexes and everything. But what's important here is that just for small perturbation,
