You’ve felt it before.
That weird moment on an escalator where your brain asks,
“Why is this moving at this speed?”
Not fast.
Not slow.
Just uncomfortable enough to feel intentional.

In this episode of Explaining Everything, Professor Everything breaks down the physics, psychology, safety codes, and human awkwardness that determine the exact speed of escalators around the world.
It’s not a bad design.
It’s survival engineering.
