Because they were introduced by different people at different times, they did in some sense fall "from the sky as random and unrelated drops of rain." However, there is no need for the students to relive this history when the concepts can be introduced in a unified manner.

In a survey of commonly used calculus textbooks (Refs. 14-17). I found no problems involving partial derivatives where "all other independent" and "all other" variables were not equivalent.

Ashley Carter and Ralph Baierlein explicitly introduce and discuss the properties of Legendre transforms in their texts (all texts implicitly introduce Legendre transforms, when they define F, G, and H). Similar to what I propose here Carter illustrates the Legendre transform's use with abstract variables (rather than E, S, and F, etc.). What I suggest in this paper is that these introductions can be better targeted to deal with misunderstandings that have not been previously dealt with, and to confront the student with the reason for and the meaning of thermodynamic notation.
