Question

The approach to derive the properties of a bigger, more complex, system from the properties and interactions of its constituent simpler parts is called
(A). Reduction
(B). Simplification
(C). Unification
(D). Modification

Answer 1

We can collectively establish physics as a study of the underlying laws of nature and their illustration in different natural phenomena.
Unification and reduction are two principal driving factors in physics.

Complete step by step answer:
We can extract the features of a bigger or more complex system from the characteristics of its constituent simpler components. This method of analysis is termed reductionism and is a major feature of physics. For example, let us consider thermodynamics that was researched widely in the nineteenth century. It had dealt with systems with bigger macroscopic factors like temperature, internal energy entropy, etc. Later advancements in research introduced kinetic theory and statistical mechanics. These mechanics studies a system in terms of the molecular components of the system. This is called reductionism as it studies a system in terms of its smaller constituent factor to get a clear picture of its characteristic features rather than studying the system as such in bulk.

There are so many theories and laws being developed in physics based on various studies and researches. Some of these laws may be applicable to different phenomena. So, there comes the need for unifying these laws or theories that are valid for different systems. This process is termed as unification.

A given set of problems can be solved using different methods. One could always take the simplest one to solve. So this property of considering the simplest method of solving or analyzing a particular system is termed as simplification.

So, the correct answer is “Option A”.

Note:
Modification could help in better understanding and make the observations more clear and transparent. With the new advancements in the studies, these properties also keep on updating.
The modification is the process of amending or modifying the already established set of theories or laws based on the new advancements.
