Ramsey theory

Ramsey theory is a branch of mathematics that explores conditions under which order must appear in chaotic or random structures. It suggests that in any sufficiently large system, some structure or pattern must emerge, regardless of how elements are arranged. For example, if you gather enough people, you will always find either a group of friends or a group of non-friends among them. This theory highlights the unavoidable presence of organization in large datasets or systems, underlining a fundamental principle of combinatorial mathematics.
