Brilliant and concise response! You really bring home the point that the Temperature concept can be constructed mathematically and illustrated in any number of ways.I would almost liken it to how we keep track of TIME, and how we have had several different calendars at different points in our history. What advancements do you see in the field?

Perhaps I’m having a misunderstanding but perhaps you could clarify? Is my supposition that the feasibility of achieving 0 IS actually possible?As you stated if the two systems were ever to be in contact heat would flow from negative to the positive system thereby reverting to just 1 Positive?

Can’t go negative on absolute zero….I think your confusing two separate systems.While just slightly different it is a difference nonetheless!

“Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.” This is Wikipedia’s definition. This field contains possible advancements in superconductivity, superfluidity as well as unknown physics because atoms,protons,etc etc begin to act in unrecognizable configurations! Scientists have recently been able to turn light into liquid is one of the interesting feats accomplished for your viewing pleasure
