Arrow of Time: Towards a New Epistemology of Science :: Scientific Philosophy Philosophical Papers

Arrow of Time Towards a New Epistemology of Science abstractedness Humanity has tried to comprehend two fundamental events since judgment of conviction antique the birth of the universe and the emergence of life. Recently, it is claimed that these events can be understood comprehensively by means of a metaphor the cursor of time. The purpose of the present written report is twofold (1) to build an epistemological structure that underlies the principle of times arrow and (2) to act on the unity of science in a novel fashion. (A) WHAT IS AN ARROW OF duration?The events which we see in the universe are classified into two categories the rechargeable and the ir correctable. The arrow of time is relevant to the latter than the former. It is alongwith the correctable-irreversible syndrome that a major lighten can be thrown on the nonion of times arrow.Concept of ReversibilityThe reversible events are those which occur regularly and repeatedly, the cycles of seasons, harvesting , p endulum swinging in a frictionless medium , the motion of earth and the moon , are some of the examples. Reversibility is an idealized concept . A process is said to be reversible if and only if the system which undergoes that process together with all parts of its purlieu which are affected, can be restored reproducibly to their original states. In short, in the reversible process all relevant parts of the universe essential be capable of being put back to how they were Time is not so considered to be an important ingredient in this system. The entire Newtonian Science is of this sort. Newtons laws , Maxwells equations, Einsteins general relativity and even quantum mechanics- all remain in effect unaltered if we reverse the direction of time ( Replace the t which represents time by -t ). Even in life and the social sciences, time is not considered to be important component in these system of knowledge.The notion of times arrow is very important in the context of irreversible p rocesses.Irreversibility definedIrreversibility is the negation of reversibility. It is a realistic notion. Moreover, it is the one-way time evolution of the system, giving rise to the non-repetitive , non-cyclic processes or events. The examples are , mixing a milk in the coffee, transfer of catch fire from a hotter body to a cooler one, chemical changes, the state of agitation and chaos, rhythms, non-equilibrium systems, metabolism etc. Irreversibility is an open system in the sense that it interacts with its contact area and evolves simultaneously.
