Cantor (Georg Cantor)

Georg Cantor was a German mathematician best known for founding set theory, which explores the concept of infinity and the size of sets. He introduced the idea that not all infinities are equal; for example, the set of real numbers has a greater "size" than the set of natural numbers. Cantor developed the notion of cardinality to compare different infinite sets, revolutionizing mathematics and influencing various fields such as logic, topology, and even philosophy. His work challenged traditional views on infinity and laid the groundwork for modern mathematical analysis. His ideas, once controversial, are now fundamental in mathematics.
