The second law is offered as a simple observation in the same essay but its status as Clarke's second law was conferred by others. It was initially a derivative of the first law and formally became Clarke's second law where the author proposed the third law in the 1973 revision of Profiles of the Future, which included an acknowledgement.

[1] [2] [3] A more fundamental statement was later labelled as the zeroth law after the first three laws had been established. The zeroth law of thermodynamics defines thermal equilibrium and forms a basis for the definition of temperature: if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium ...
Newton's laws of motion, three physical laws that, together, laid the foundation for classical mechanics; The laws of thermodynamics, originally three physical laws describing thermodynamic systems, though a fourth one was later formulated and is now counted as the zeroth law of thermodynamics
The same work also contained "Clarke's First Law" and text that became Clarke's three laws in later editions. [44] In a 1959 essay, Clarke predicted global satellite TV broadcasts that would cross national boundaries indiscriminately and would bring hundreds of channels available anywhere in the world.
The third law of thermodynamics states that the entropy of a closed system at thermodynamic equilibrium approaches a constant value when its temperature approaches absolute zero. This constant value cannot depend on any other parameters characterizing the system, such as pressure or applied magnetic field.

In the preface for Reach for Tomorrow, Clarke notes that "Time's Arrow is an example of how hard it is for the science-fiction writer to keep ahead of fact. The quite – at the time the story was written – imaginary discovery described in the tale now actually exists, and may be seen in the New York Natural History Museum."
If A, B, C are thermodynamic systems such that A is in thermal equilibrium with B and B is in thermal equilibrium with C, then A is in thermal equilibrium with C. The zeroth law is of importance in thermometry, because it implies the existence of temperature scales. In practice, C is a thermometer, and the zeroth law says that systems that are ...
