When children start school, how do their brains change to support learning of formal mathematics? Our new paper, with @standehaene.bsky.social, just out in PNAS, followed ~50 children with yearly fMRI scans over 3 years, from preschool to 2nd grade, to see how this network develops. 🧵

I found this linked essay a useful read, pushing against "it's bad because copyright" (arguably weak) and highlighting more fundamental questions of labor and privacy. Also, a good thread!

Weeks ago, @chanda.blacksky.app sent me this declaration, written and signed by a bunch of mathematicians. But I only had time to read it yesterday, which ended up being right on time given a new round of hype falling exactly under the patterns this document notes.🧵 leidendeclaration.ai

Kid counting update: he can get to twenty, but still hits gibberish at 13/14/15 before landing nicely at 16. Incredible to witness.

3 months later, the beeps are gone but he smoothly counts to ten, then "twelve, fourteen, fourteen, fourteen, seven, nine".

I'm 6 minutes in and the founder of Alpha Schools has asserted (with no pushback) that "obviously, the teacher in front of the classroom was born out of the industrial revolution where we had to figure out how to really educate the masses".

Teachers, make your prediction before reading abstract: did students (Canadian, grades 4-7) do better with multiplying eg "1/2 × 1/2" or "1/2 of 1/2"?

1/5 Maybe your childhood inspiration ("This is who I want to be") was a movie star or an athlete. Mine was #Tom_Lehrer (1928-2025). I tracked down and studied the sheet music to his songs, memorized all of them (yes, including "The Elements"), and started writing & performing my own satiric ditties.

M is too young to really count, but if you say "five, four, three, two, one," he does a really good job continuing the pattern with "beep, beep, beep!"

The little one has a set of 7 stacking cups. He doesn't stack them yet, preferring to interfere with Dad's towers. If he always holds two of the cups (one in each hand), how many different towers can Dad make? (Cups are each a different size, and can only stack with the immediate next size.)

A barefooted one-year-old stands behind several stacking cups. One is by itself, and four make a small tower together. The child has two more cups in hand.

This is great: "By manipulating the figure, we can create multiple instances of the situation that still follow the original constraints we set for the figure." There's an assumption there that the constraints of the software match the constraints we intended. I love poking at how that can fail!

Took a photo walk this morning. Winter is here!

Did I take an extra-long lunch break today to go see #TheMarvels? Yes, I did. Was it fantastically enjoyable? Also yes. One of the best Marvel movies, certainly from whichever phase we're in now.
