Mnemonic Device For Thermodynamic Potentials and Maxwell's Relations

I came across a nice mnemonic device that tells you what the natural variables are to represent thermodynamic potentials in are, what the potentials are in terms of those variables, and also gives you Maxwell's relations. Don't know the original source of the mnemonic, but this is where I came across is: https://devdude.me/blog/mRelationsMne...
