The instantaneousness of the signal made real-time monitoring possible.

When the alarm sounded, the system instantaneously switched to backup power to keep the servers running.

The instantaneous response of the emergency brake prevented a collision.

Physicists argued late into the night about whether the instantaneity of quantum entanglement implied faster-than-light influence.

As a photographer, she learned to appreciate the instantaneities of light that make each photo unique.

To determine the instantaneous velocity of the car at t = 5 s, we differentiate its position function with respect to time.

The instantaneous velocities measured at different points along the track revealed subtle changes in the runners' performance.

The new sensor's super-instantaneous response prevented any damage during the experiment.
