The discussion revolves around the notation used in partial differentiation, specifically the meaning of subscripts in expressions like \(\left(\frac{\partial x}{\partial y}\right)_z\). Participants are exploring the implications of this notation in different contexts, particularly in relation to its use in fields such as Thermodynamics.
The conversation is ongoing, with some participants providing insights into the meaning of the subscript and its relevance in specific disciplines. There is a recognition of the notation's rarity in Mathematics compared to its prevalence in other fields.
Some participants note that the notation indicates holding certain variables constant while differentiating, which may not be immediately clear to those encountering it for the first time.
Amos Axiom said:Is that any different from a regular partial derivative though? I've started to encounter the notation in literature and am finding it strange.
