While working on the revision of the Equational Theories Project (ETP) report at https://arxiv.org/abs/2512.07087 I came across an observation that we quietly made at the back of that report (see Section 14.1) but has become more relevant today. The ETP was a successful project, running over several months, to resolve over 22 million implications in universal algebra (and formalize them in Lean) through a variety of methods, both human and automated, although in our case the automation was much more in the ``good old-fashioned'' form of utilizing automated theorem provers (ATP) and simple scr…

And that's why when kids get to algebra and they start to struggle, the issue is not the algebra. The issue is the third grade math facts they didn't learn. And the way to fix the problem is not pound them with more algebra. It's to go fix the third grade problem.

The book that sparked my interest in discrete math and abstract algebra. Other books by Simon Singh are also fantastic.

And um if you build a specialized chip for low precision dense linear algebra and can't do anything else that turns out to be really useful for machine learning inference uh even though it can't run Chrome or Word or whatever.

Formalising a proof in Lean currently takes about ten times the effort of writing it out: doable, but annoying.Their words
So right now I estimate that the time and effort taken to formalize it, proof is about 10 times the amount taken to write it out. So it's doable, but it's annoying.

What is a korrent?
A korrent is a belief a person has stated in their own words: one sentence stating the claim, backed by a quote and a source, kept at korrents.com.
Under a name here, the quoted block is what they actually said. The korrent beneath it is the claim those words support, in korrents' wording — tap it to see the record, its source, and who else holds it.
Nobody here wrote their own korrents. They are compiled from public statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they do, this site shows a machine translation beneath the post, in this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the serif above is exactly what the person published, and it is what to quote them on. A translation can be wrong in ways that matter, especially about tone.
Only the post's own words are translated. A quoted post, a linked article and a belief on korrents.com are left in their original language.
