IN BRIEF: Equipment designed to serve a specific function.

Scientific apparatus offers a window to knowledge, but as they grow more elaborate, scientists spend ever more time washing the windows. — Isaac Asimov (1920-1992)

Tutor's tip: A science teacher can use an "apparatus" (tools or instruments) to demonstrate the laws of physics, while a history teacher can explain the downfall of the "Apparat" (political bureaucracy of the former Russian Communist Party).
