Energy Dissipation

Definition

Energy dissipation refers to the process through which energy is transformed into a less useful form, typically as heat, during various physical processes. This concept is particularly significant in understanding complex systems where energy loss can influence behaviors and outcomes, such as turbulence in fluid dynamics and market fluctuations in finance.
