Set theory was founded by George Cantor. He was a German mathematician and developed set theory towards the end of the 19th century. Set theory is mainly concerned with understanding the properties of sets, which are unrelated to specific elements that make up them up. This means that the theorems of set theory are related to general sets, whether these sets are physical objects or pure numbers. Although most people find set theory inapplicable to real life, it can be applied in different situations in real life.
The value of set theory is not in the mathematics is contains but the in the language. The purpose for learning set theory is not in its application like the way Fourier analysis can be applied in life. However, set theory has been considered important in helping to describe things. Even computer scientists have found a describing basic concepts like Turing machines using the language of set theory (Prontes, n.d). When objects are specified using set theory, everyone understands that you are talking about.
