The Collatz conjecture has plagued mathematicians for decades—so much so that professors warn their students away from it ...

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.

An attempt at tackling the intractable Collatz conjecture is a “noble failure” demonstrating the promise of automated reasoning techniques.

The Collatz conjecture is also known as the “3n + 1” problem. It’s an easy problem to explain and check, and has been tested up into the nineteen figure range. But it’s only now that ...

Seaweed? Worms? Bad hair day? The animation below is a new way to look at the Collatz conjecture, one of the most high-profile open problems in mathematics. The conjecture is easy to explain ...

Despite recent progress on the notorious Collatz conjecture, we still don’t know whether a number can escape its infinite loop.

The Collatz Conjecture Is a Simple Problem That Mathematicians Can't Solve A kid can understand the question, but no one can answer it.
