Physical Time and Time Clock

Authors: Daniele Sasso

Time is a fundamental quantity in physics and its definition has generated many problems starting from Newton’s philosophical absolute time. Einstein searched for giving an operative definition of time through the use of unreal ideal clocks and of rays of light. In this paper we will search for giving a physical definition of time pointing out the necessity of avoiding in physics mistakes connected whether with Newton’s exclusively philosophical definition, taken out of the scientific context, or with Einstein’s operative definition through unreal clocks. We will prove nevertheless also the use of real clocks raises generally problems because of their real working and of the inadequacy of measuring instruments.
