It's all over the place in physics and chemistry, and as a consequence on the engineering areas that are based on those (AKA, nearly all of them).
It is rarer to see it in CS, but it's more because CS used to deal with very simple theories up to recently than because of some fashion. As CS theories start to construct up from the earlier ones, it's appearing more.
