MEN are generally better than women on tests of spatial ability, such as mentally rotating an object through three dimensions or finding their way around in a new environment.
Rotating or moving the horizon line or other large components of the user's environment in conflict with the user's real-world self-motion (or lack thereof) can be discomforting.
It is applicable to rotating and stationary components that work in the harsh environment, such as the combustion chamber, turbine blades, turbine guide vanes, etc.
