Is "setup" an acceptable noun in formal writing?
I'm editing a draft of a scientific paper which repeatedly uses the word "setup" to refer to the, well, experimental setup. Example: > The dimensions of the setup are 250 mm ∗ 250 mm ∗ 50 mm. Every time I see the word "setup" appear by itself, I cringe a little, thinking of, say, Microsoft Windows' `SETUP.EXE`. However, the phrase "experimental setup" sounds OK. Is "*setup*" accepted as a valid word to use for an experimental apparatus, in formal scientific writing in American English?
