The second law of thermodynamics — the notion that entropy, a measure of disorder, arguably falls among the principles that have sacrosanct. In the words of the British astrophysicist Arthur Eddington in his 1928 book The Nature of the Physical World, “If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations — then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation — well, these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics, I can give you no hope; there is nothing for it but to collapse in deepest humiliation.” No one has even presented any violation of this law, and it wasn’t something that is to be expected.

Despite this, some were troubled regarding this topic. Some are not convinced that we understand it correctly or that its foundations are firm. Although it’s called a law, it’s usually regarded as merely probabilistic: It stipulates that the outcome of any process will be the most probable one.

The physicist, Chiara Marletto of the University of Oxford, said, “We like laws of physics, to be exact.” Should the second law be tightened up into more than just a statement of likelihoods with this newfound information?

Several independent groups have participated in this debate. They may have woven the second law out of the fundamental principles of quantum mechanics — which, some suspect, have directionality and irreversibility built into them at the deepest level. As per this latest view, the second law is not because of classical probabilities but because of quantum effects such as entanglement. It arises from how quantum systems share information and from cornerstone quantum principles that decree what is allowed to happen and what is not.

There are multiple options through which it can be possible. Some include Quantum Inevitability, Demon in the Machine, Redefining Thermodynamics, and Hilbert’s Problem.

In conclusion, there are still physicists working on Hilbert’s sixth problem and attempting to reformulate quantum mechanics and its more abstract version, quantum field theory, using axioms that are simpler and more physically transparent than the traditional ones.

In the words of Einstein, “A theory is the more impressive the greater the simplicity of its premises.”
