Mathematicians regard the Collatz conjecture as a quagmire and warn each other to stay away. But now Terence Tao has made more progress than anyone in decades. Experienced mathematicians warn ...

We almost have a solution to an exceptionally tricky mathematical riddle first posed 82 years ago. The problem, known as the Collatz conjecture, is easy to state. Start with any positive whole number.

This column comes with a warning: Do not try to solve this math problem. You will be tempted. This problem is simply stated, easily understood, and all too inviting. Just pick a number, any number: If ...

The Collatz Conjecture begins with a simple sequence yet no proof has ever been found to solve it. Judge in Charlie Kirk shooter case appears to warn Trump as he says he won’t ‘put finger on scale of ...
