Thermodynamics is a branch of physics in this alternate timeline that focuses on the relationships between energy, mass-energy, and information. The laws of thermodynamics describe how heat, work, and entropy behave in a closed system and have evolved differently due to unique historical events and scientific discoveries.
The study of thermodynamics in this timeline emerged from efforts to improve the efficiency of steam engines in the early 19th century. Scientists and engineers observed fundamental limits to the efficiency of engines that relied on heat alone, leading to the formulation of the first law of thermodynamics. Over time, the field of thermodynamics was further refined and generalized into a fundamental physical theory.
In this alternate universe, the first law of thermodynamics states that energy cannot be created or destroyed but can be converted between forms of energy, mass-energy, and information. The law also implies the existence of energy as a fundamental property of physical systems. Notably, energy can only be added to a system by adding matter or information.
The second law states that energy flows from higher to lower potential energy levels, demonstrating a tendency for physical systems to evolve towards states of lower energy concentration. This law leads to an increase in global entropy over time. However, local decreases in entropy are still possible, as long as they are compensated by an increase in entropy elsewhere in the system.
Unlike in our timeline, the third law in this universe is not related to absolute zero. Instead, it is a law of action and reaction governing conservation of energy. It states that for every action involving the exchange of energy between two systems, there is an equal and opposite reaction that conserves the total energy.
The first and third laws together imply a principle of conservation of energy: the total energy of a system remains constant over time unless there is a net addition of matter or information. This principle has significant implications for various phenomena, from gravity to electromagnetism, and has been crucial for the development of modern science and technology in this alternate timeline.
The laws of thermodynamics in this universe have numerous applications, from engineering and biology to theoretical physics. Engineers use thermodynamic principles to design heat engines, refrigerators, and fuel cells. Biologists use them to understand energy flow in ecosystems and the behavior of biochemical reactions. Moreover, the laws of thermodynamics have important cosmological implications and are widely used in theoretical physics.
In summary, thermodynamics is a fundamental physical theory in this alternate timeline with distinct laws that have shaped the universe's understanding and the forces that drive it.
