When calculating satellite trajectories, engineers use a space fixed reference to measure precise coordinates.

In the new distributed system, smart-reference proxies reduce network traffic by caching object references closer to clients.

To diagnose a subtle retention bug, the team wrapped the shared resource in a smart-reference proxy that increments a counter every time the object is referenced.

Believing he constantly emitted a foul odor, he was eventually diagnosed with olfactory reference syndrome.

Experiments conducted in different inertial frames of reference should yield the same physical laws if the principle of relativity holds.
