Fun fact: This international ranking of scholars has ranked me as fifth in the world of all time in terms of "Markov chain" research citations (and 57th in "probability" overall). It's probably a pretty questionable ranking algorithm, but I will take it.

After last night's tough loss, my statistical model now gives the #BlueJays a 56.84% chance of prevailing in tonight's seventh game. It'll be tight. Let's go Blue Jays!

With last night's convincing win, my statistical model now gives the #BlueJays an 81.4% chance of winning the World Series. Go Jays Go! :-)

For Maths fans, 2025 is a square.
45² = 45 x 45 = 2025
Also,
9² x 5² = 2025
40² + 20² + 5² = 2025
My favourite?
1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025

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 — the casual racism, the bullying blue checks,
