Collatzeral damage: bitwise and proof foolish (soatok.blog)
Let’s talk about the Collatz Conjecture, which is like mathematicians’ original version of this programmer joke:

Lemma for the Fundamental Theorem of Galois Theory (susam.net)
This post illustrates a key lemma that is used in proving the fundamental theorem of Galois theory (FTGT). Note that FTGT is not covered in this post. The focus of this post is on understanding and proving this lemma only. Here is the lemma from the book Galois Theory, 5th ed. by Stewart (2023):

A Proof of the Collatz Conjecture (arxiv.org)
In this paper, we show the new fixed point theorem in metric spaces. Furthermore, for this fixed point theorem, we apply to the Collatz conjecture.

'Once in a Century' Proof Settles Math's Kakeya Conjecture (quantamagazine.org)
The deceptively simple Kakeya conjecture has bedeviled mathematicians for 50 years. A new proof of the conjecture in three dimensions illuminates a whole crop of related problems.

How to prove false statements? (Part 1) (cryptographyengineering.com)
If you’ve read my blog over the years, you should understand that I have basically two obsessions. One is my interest in building “practical” schemes that solve real problems that come up in the real world. The other is a weird fixation on the theoretical models that underpin (the security of) many of those same schemes.

New Proofs Probe the Limits of Mathematical Truth (quantamagazine.org)
By proving a broader version of Hilbert’s famous 10th problem, two groups of mathematicians have expanded the realm of mathematical unknowability.

How many real numbers exist? New proof moves closer to an answer (2021) (quantamagazine.org)
For 50 years, mathematicians have believed that the total number of real numbers is unknowable. A new proof suggests otherwise.

Fermat's Last Theorem – how it’s going (wordpress.com)
So I’m two months into trying to teach a proof of Fermat’s Last Theorem (FLT) to a computer. Most of “how it’s going” is quite tedious and technical to explain: to cut a long story short, Wiles proved an “R=T” theorem and much of the work so far has gone into teaching the computer what R and T are; we still have not finished either definition.
