ABSTRACT
Dissipation in physics is strictly related to the concept of dynamics. Indeed, friction or turbulence causes a degradation of energy over time. This energy is typically converted into heat, which raises the temperature of the system. Such systems are called dissipative systems. Formally, dissipating forces are those that cannot be described by a Hamiltonian. This includes all those forces that result in the conversion of coherent or directed energy flow into an undirected or more isotropic distribution of energy (e.g., the conversion of light into heat).
