History of Mathematics
Cardinality refers to the measure of the 'size' of a set, indicating the number of elements contained within that set. This concept is crucial in understanding the nature of different sets, especially in distinguishing between finite and infinite sets, as well as different types of infinities, such as countable and uncountable infinities. The rigorous exploration of cardinality has significant implications in set theory and analysis, forming a foundational aspect of modern mathematics.
