Accelerator physicists carefully reserve the term "cooling" for non-Hamiltonian processes, where Liouville's theorem (1838) is violated; i.e. where there is an increase in phase space density of the beam. Unlike hadron beams, high-energy electron beams can radiate energy quite easily and, thus, beam cooling can be achieved through synchrotron radiation damping. In hadron beams, there is a good number of methods for beam cooling, but usually, they are limited to a narrow range of beam parameters. In this talk I will review hadron beam cooling methods and describe possible applications and ultimate possibilities of these techniques.
