Meanings of stationary point in English

Optimal experimental conditions were selected from the stationary point of the response surfaces.

Thus, something else had to be changing when light travels a greater distance when observed from a stationary point.

To rotate means to turn around and around, but doesn't that imply the existence of a stationary point of reference?

In case the worlds are equal in mass, they will both take the same orbit around a central stationary point, midway between the two.

The stationary points identified herein can be overlaid into a protein structure to assist in generating initial guesses for large model systems.

Comparisons of geometries and relative energies of stationary points (minima and transition states) with density functional results indicate that the semiempirical method is reasonably accurate.
