Study of the physical world (7)

Ross

I believe the answer is:

science

'study of the physical world' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for science that I've seen before include "a sort of fiction" , "Eg, chemistry, physics" , "Biology, for example" , "Biology, perhaps?" , "Critically tested knowledge" .)

I've seen this clue in the Sydney Morning Herald.
