Is 'exact science' always used positively?

Not always. It is positive when describing a field's rigour, but often used in the negative ('not an exact science') to highlight uncertainty, sometimes with a slightly dismissive tone towards fields that claim too much precision.

Can 'exact science' be plural?

Yes, 'exact sciences' is common when referring to multiple fields like physics, chemistry, and mathematics collectively.

What is the main difference between 'exact science' and 'hard science'?

They are largely synonymous. 'Exact science' emphasises methodological precision and provability. 'Hard science' often contrasts with 'soft science' and may emphasise quantitative methods and natural subject matter.

Is computer science an exact science?

This is debated. Its theoretical foundations (e.g., algorithms, computability) are highly exact. Its applied aspects (e.g., software engineering, human-computer interaction) are often considered less exact due to human factors.

Common Mistakes

Using 'exact science' to describe something that is simply 'accurate' (e.g., 'His report was an exact science').
Misspelling as 'exact sience'.
