FYI: this is mostly a copy-paste of the issue description, I suspect it's something that already approved.

I did few additions:

1. reference to the Khinchin's book (I appreciate any other source)
2. small preamble for the fractions.md
3. last section with a reference to the formal proof.

Looks fine to me.

Nit: not sure what the line-length conventions should be for Markdown files. The file is currently 1 file line per paragraph. Is it worth reflowing?

Other files wrap lines close to PEP 8 limit. Though, not all. E.g. InternalDocs/stack_protection.md.

It's just to simplify comparison with the issue description.

Please do wrap, for people viewing locally in non-wrapping editors it makes life much easier.

Ok, done. Though, I suspect people will want to see rendered TeX...

@mdickinson if you’re happy, I can merge this, could you please review?

I won't be in a position to review effectively for around a week (on vacation without access to a real keyboard; phone doesn't count). I'm sure any changes I might ask for would be nitpick level, and I don't want to block this. I'm happy to do a post-merge review next week. Thanks @skirpichev for pushing this through!

I'm afraid I'm not familiar enough here to review properly, but I think a week's wait should be alright.
