Our thermodynamic understanding of systems driven by electromagnetic, mechanical, and chemical energy is far more advanced than that of other forms of energy. As the relationship between information and energy is rather diffuse, we might as well start with kinetic energy to get an understanding of it. Kinetic energy is the energy expressed by the movement of free moving atoms or molecules in a gas. It reflects the temperature of the system. To understand the fundamental meaning of information we have to explore the physical concepts upon which it is built, such as kinetics and thermodynamics. Basically, we want to understand the deep meaning of the equation defining Helmholtz Free Energy.
