For Maths fans, 2025 is a square.
45Β² = 45 x 45 = 2025
Also,
9Β² x 5Β² = 2025
40Β² + 20Β² + 5Β² = 2025
My favourite?
1Β³+2Β³+3Β³+4Β³+5Β³+6Β³+7Β³+8Β³+9Β³ = 2025

Knock on Wood

Happy Friday the Thirteenth! I was actually BORN on a Friday the Thirteenth. In fact, "Born on Friday the Thirteenth" was my proposed title for my book about luck, eventually called Knock On Wood. Oh, did I mention that it makes a great Christmas present? πŸ™‚ probability.ca/kow/

Richie Assaly: I grew up on Twitter. But with a new Trump era on the horizon, I’ve turned to Bluesky. Here’s what I found there On its surface, the apps almost identical to the old Twitter. But gone, at least for now, is much of the noise β€” the casual racism, the bullying blue checks,

Is Bluesky the real deal or just more of the same?
