Dec 7, 2020 at 6:23 comment added Steven Landsburg If you're not familiar with Witt vectors, you might want to read about them. You can construct the $p$-adic integers (or an unramified extension thereof) by starting with a finite field and applying Witt's construction, which has the flavor of starting with formal power series and tweaking the addition/multiplication rules.
