I have just noticed that you can use mathjax in this website, i.e. in Physics meta, but why?
Here for example:
But mathjax is used only when you ask serious question in physics or mathematics and etc..., but serious question in physics should not be asked here on meta, but on physics stack exchange instead.
In physics meta you ask general questions about the physics stack exchange website, but when you ask these questions, you need only html, but not mathjax. You won't ever use mathjax here, so why you can use here mathjax at all?
