It Takes A Lot Of Work To Exist Thermodynamics Planner

No need to be a physics major or physicist to enjoy this planner featuring the Carnot heat engine, along with the wry truism saying "It Takes A Lot Of Work To Exist 24 Hours A Day, 7 Days Per Week, 365 Days Per Year". Specifically, this planner features the second law of thermodynamics. Since any thermodynamic engine requires such a temperature difference, it follows that useful work cannot be derived from an isolated system in equilibrium; there must always be an external energy source and a cold sink. Educational physics attitude planner for anyone who works in the thermodynamic sense of the word!
