SET THEORY
The set theory of sets lies at the foundation of mathematics. Concepts in set theory such as functions and relations appear explicitly or implicitly in every branch of mathematics. The fundamental concept of all branches of mathematics is that a set.
George Boole was born on November 2,1815. His father was a shopkeeper. He pointed out that there was a close relationship between symbols that represents logical instructions and algebraic symbols.Boole would be pleased to know that his Boolean algebra is the basis of all computer arithmetic.At the age of 24 George Boole published his first paper "Researches on the Theory of Analytical transformation" in the Cambridge mathematical journal.
The theory of sets as a mathematical discipline originated with the German mathematician George Cantor.George Cantor was born on March 3 , 1845.
Augustus De morgan was born in Madurai, Tamlinadu. His family move to England when he was seven months old. De morgan's laws the three basic set operations Union, Intersection and complement.
