Difference between Unification and Reductionism in Physics.
Answers
Answer :-
• Two basic quests in Physics : Two principal thrusts in physics are unification and reductionism.
▶ Unification - In physics, attempt is made to explain various physical phenomena in terms of just few concept and laws . We try to see the physical world as manifestation of some universal laws. For e.g., the same Newton's law of Gravitation can be used to describe the motion of a body falling towards the earth, motion of the moon around the earth and motion of planets around the sun. Attempts are being made to unify fundamental forces of nature in the persuit of unification.
▶Reductionism - Another attempt made in Physics, is to macroscopic system in terms of its macroscopic constituents. This persuit is called reductionism. For example, thermodynamics was developed to explain the macroscopic properties such as temperature, internal energy, entropy, etc. of the bulk systems. Later on, these properties were explained in terms of molecules in kinetic theory and statistical mechanics.
★ More to know :-
• An exciting field of research these days is a new domain, called mesoscopic physics, which is intermediate between the microscopic and macroscopic domains and deals with a few tens or hundreds of atoms.
• The scope of physics is very wide. Every event, which occurs around us in our daily life, is governed by one or the other principle of physics. One way of getting the idea of the scope of physics is to look at its various sub - disciplines. Another way is to look at the vast ranging of magnitude of the physical quantities it deals with.
Hey mate,
Unification: It is the act of unifying the different laws valid for different phenomena in to a single theory that explains all the different phenomena. Eg. ... These are unified under theory of electromagnetism; Reduction: It is the effort to solve a complex problem by breaking it into simpler parts.
