Zermelo

Zermelo is a mathematician famous for his work on set theory and the foundation of mathematics. He introduced the concept of the Axiom of Choice, which states that given any collection of non-empty sets, it's possible to select exactly one element from each set, even if there's no explicit rule for doing so. This axiom helps prove important theorems but also leads to some counterintuitive results. Zermelo’s contributions helped formalize mathematicians’ understanding of collections and infinity, shaping modern mathematics’s logical structure.
