Some years ago, I wrote here about “hailstone numbers” (Follow that hailstone, 8 April 2016). These are numbers that are generated when you try your hand at the Collatz Conjecture—sometimes described ...

There are some news items from the past year that deserve a second chance. Here we have one such - although not as well known as the long standing P=NP conjecture, Collatz has fascinated people for ...

Pick a number; if it is even, divide it by 2; if odd, triple it and add 1. Now repeat the process, each time halving or else tripling and adding 1. Here is a surprise: no matter what number you pick, ...

The Collatz Conjecture is a deceptively simple math problem. It has only two rules. First, pick any number. If it's even, divide it by two. If it's odd, multiply it by three and add one. This will ...

The Collatz conjecture is an unsolved conjecture in mathematics. It is named after Lothar Collatz, who first proposed it in 1937. The conjecture is also known as the 3n + 1 conjecture, as the Ulam ...

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 anyone has come ...

Kevin Lieber of Vsauce2 examines why the Collatz Conjecture is still a complex mathematical mystery. Toyota's Ford Maverick fighter just got a lot more real JD Vance and the Trump team keep moving the ...

If you have ever thought that working out a Collatz sequence by hand was alright but lacked buttons and lights, the Collatz-o-matic by [mechatronicsguy] has you covered! The device is a type of Tag ...

SINGAPORE - Prime Minister Lee Hsien Loong announced on Friday (Dec 20) that he will be on leave from Dec 21 to Jan 3. During this time off, besides plans to spend time with family and "perhaps go ...
