Set Theory: A formal system for studying collections of objects, serving as a foundational language for modern mathematics.
Infinity: A concept denoting endlessness or boundlessness, which Cantor rigorously defined and categorized into different sizes.
Transfinite Numbers: Numbers used to quantify the sizes of infinite sets, extending the concept of number beyond finite quantities.
One-to-one Correspondence: A bijective mapping between elements of two sets, used to determine if they have the same cardinality.
