Only for the truly stationary observer will the tension in the string be explained using only the observed rate of rotation.

To the stationary observer, however, the walker travels a spiral path.

Over 165,000 stationary and mobile observers were prepared to act as election day observers.

To find the appropriate boundary conditions, consider a stationary observer just outside the horizon at position .

The horizontal corresponds to the usual notion of simultaneous events, for a stationary observer at the origin.

For the stationary observer, as the spaceship and electron pass through his detector (a very big one!)

It differs in speed and direction from the true wind that is experienced by a stationary observer.

The little machine with the stubby wings screamed past a stationary observer, twisting as it passed him.

In all cases, the shape and colour observed were changed by the devices for a stationary observer.

The dotted horizontal line represents the set of points regarded as simultaneous with the origin by a stationary observer.
