    added some minimum content to perfectoid space. Also added a corresponding paragraph to function field analogy.

    Since my chapter in What is a mathematical concept? appears next to Michael Harris’s ’The perfectoid concept: test case for an absent theory’, when I get a chance to read that it would fun to see what sense I can make of the idea.

    A throw-away thought: if, as Scholze says, perectoids were devised to mediate between p\mathbb{Q}_p and 𝔽 p((t))\mathbb{F}_p((t)), and

    Although these two fields have formally ’the same’ elements, the basic addition and multiplication operations are different: In p\mathbb{Q}_p, one computes with carry, but in 𝔽 p((t))\mathbb{F}_p((t)) without carry,

    is it interesting that carrying is a form of cohomology?
