A circadian rhythm is a natural internal process that regulates the sleep–wake cycle and repeats on each rotation of the Earth roughly every 24 hours. It can refer to any biological process that displays an endogenous entrainable oscillation of about 24 hours. These 24-hour rhythms are driven by a circadian clock and they have been widely observed in plants animals fungi and …

A nuclear reactor formerly known as an atomic pile is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion.Heat from nuclear fission is passed to a working fluid ( water or gas) which in turn runs through steam turbines.
