Quantum Thermodynamics and the Law of Scale Independence

Law of scale independence means something applies whether the thing is small or big, independent of its scale. It's not like laws of physic should apply to big things and not small things. The laws of quantum theory should apply every ere no matter the size of things. And in reverse, so to speak. So the laws of thermo dynamics, which are found to apply to heat engines, big things, should also apply to small things as well. In both cases, quantum therian thermodynamics, it must be the case that the laws are scale independent. But if things do appear in some way and a problem, which it is here, then we should seek to solve the problem.
