The second law of thermodynamics states that in any natural thermodynamic process, the total entropy of a system and its surroundings always increases over time, leading to the concept of irreversibility. This law explains why energy transformations are not 100% efficient and why systems naturally progress towards thermal equilibrium, where entropy is maximized.

Thermal equilibrium is a state in which two or more objects in thermal contact no longer exchange energy through heat, resulting in a uniform temperature across the system. It is a fundamental concept in thermodynamics that underlies the zeroth law, which allows the definition of temperature scales.

Entropy maximization is a principle in statistical mechanics and information theory that suggests systems will evolve towards states with the highest entropy, reflecting maximum disorder or uncertainty. This principle underlies many natural processes and is used in machine learning to ensure that models capture the most unbiased and diverse representations of data.
