9 The Second Law of Thermodynamics
The second law in the formulation of the maximum efficiency of a heat engine remains unaffected. The expression
is invariant, no matter with which factor the temperatures are transformed. The upper bound for the efficiency of a heat engine does not change for a fast-moving observer. Also for him it is impossible to build a 'perpetual motion machine of the second kind' ...

invisible extra dimensions and the invisible parallel universes, I have derived
