I don't know my plan for Twitter/X. It is hard to give up after all the great people I've met and conversations I had in 13+ years, but the math community has moved to Bluesky. I will use divbyzero.bsky.social as my go-to site for posting math content now. Join us there!
In case you are moving to Bluebky, you can find me here: bsky.app/profile/divbyz…
Here's a fun little "magic trick." Can you figure out how it works? Hint: even and odd numbers. I was thinking you could roll a die to determine how much to count each time. (I saw the trick was credited to Martin Gardner—true? Source?) youtube.com/watch?v=DaWcL3…

(Inspired by @divbyzero) In an effort to get something other than politics into your feed, a fun fact about ‘49’ The sum of the digits of the square of 49 (2401) is the square root of 49 (More in the image below) Src: Issue 49 of #SixSTEMTweets newsletter Link in alt text
In an effort to get something other than politics into your feed: A Munchausen number is the sum of its digits raised to the power of that digit. 1=1¹ and 3435=3³+4⁴+3³+5⁵ are the only two examples if 0⁰ is defined as 1. If we take 0⁰=0, then 438579088 is another.
