"They Use ∂ Differently in Math and Physics. Which is Better?"

Hello everyone,

I stumbled on a very well-made exposition video, which covers a subtlety in
the meaning of  "partial derivative" between mathematics and physics:

Aside: This topic is not directly related to current conversations about
derivative syntax for "intent".

Instead, the presenter has some well-reasoned general discussion, a
community proposal for adding yet-another notation, and showcases some of
the problems that our generator tools also face when trying to infer
Content MathML expressions from human-authored math syntax.

Greetings,
Deyan
