Or it could be said science is a range of disciplines born of philosophy, historically. Specializers applying and refining carefully structured thinking (philosophy) to specific fields.
But I know what Jonsnow means, in modern times 'philosophy' tends to refer to the leftover (and new) structured thinking practices that didn't evolve into an empirical science. It's only in the history of philosophy that we consider fields of science as emergent fields of philosophy, basically.
Just to avoid all that ambiguity, instead of science I might have said empirical investigation.
