Aug 21, 2020 at 21:32 comment added Philip Thinking of tensors as "matrices" always ended up confusing me. In fact, I believe you can't strictly take a trace of an object like $T^{\mu\nu}$, since this quantity will turn out to be basis dependent. I find it better to think of the "trace" for such objects to be $g_{\mu\nu} T^{\mu\nu}$. See this answer here.
