What are Numbers Made of?

The video explores the essence of natural numbers, discussing Peano axioms and their role in defining numbers without circular references. It delves into set theory, presenting Zermelo's and Von Neumann's constructions of natural numbers using Russian dolls and suitcases, respectively. The philosophical implications of these constructions are considered, emphasizing the reductionist approach in mathematics. The video concludes with housekeeping notes and responses to viewer comments.
