Talk:General theory of relativity

Question: I know we have this template for sections that get into early-undergrad math:

${\frac {d}{dx}}\sin x=?\,$

This article/section deals with mathematical concepts appropriate for late high school or early college.

But the quantitative section is going to make (gentle) reference to tensor algebra and some aspects of differential geometry. Do we have a template that somehow conveys "this section is hard-core math, but don't be scared?" Or maybe something that gets across the idea that you don't have to follow everything in this section to understand this article?
