I have a PhD in mathematics (set theory). It would be pretty tough to explain to a child. Specifically my PhD is in determinacy, which is way easier to explain than most branches of set theory, but you do need a decent understanding of infinity to really get anywhere.
Let’s assume I can prove the countability and non countability of various famous sets and, for example, that (ab)c = a^bc for cardinalities. What’s determinacy?
