For years, I thought Ennio Morricone’s haunting “scion, scion” in *Duck, You Sucker!* (*Giù la testa*, 1971), by the legendary Sergio Leone, was some mysterious vocal spell. Only now, near the anniversary of Ennio’s death (6 July 2020), I realize it was simply: Sean. The Irish name of John.

An Oxford mathematician reveals a faster way to tie your shoes. You may save five minutes over your lifetime with this trick 🙂! Unfortunately, you’ll probably spend at least ten minutes learning it... 🙁 (Isn’t this a bittersweet little metaphor for life?) Credit: www.instagram.com/reel/DKFMB6L...

Every morning, from my balcony in Milan (👇), I watch small darting birds enter the canyon between buildings. They circle for a while, then suddenly vanish over the rooftops. Which way do yours go? Clockwise? Counterclockwise? Random? Random but synced (to avoid head-on collisions)?

I recently discovered "Archive" (Gavin Rothery, 2020) almost by chance. It looks like a film about robotics, AI, grief and loss, but it is actually more disturbing and challenging than that. I also saw echoes of Tarkovsky's "Solaris", Kubrick's "2001" and Scott's "Blade Runner". Recommended.

most of you were probably wondering what it looks like to leave a pinhole camera exposure going for 8 years (preferably by sitting it on a roof and forgetting about it). well--here you go! 🔭

New Year’s resolution for 2026: make a new, detailed to-do list (since I have many leftovers from 2025). Naturally, the first item on the list is: make a to-do list. But I can’t proceed without completing the first step. So I’ll spend 2026 doing absolutely nothing but dreaming about the list.

Just discovered Cristóbal Vila (@cristobalvila.bsky.social), an amazing 3D digital artist whose work blends geometry, design, and visual craft. Explore more of his animations here: etereaestudios.com/works/ — well worth a look (and no ads or pop-ups!).

Robby the robot is a wonderful model to understand Genetic Algorithms, evolution, AI, information, memory, ... life (😳). It made me think in a new different way since I discovered it in @seanmcarroll.bsky.social "The Big Picture" and @melaniemitchell.bsky.social "Complexity". youtu.be/V1isB2lJr7I

In “Sync”, Steven Strogatz shows how systems evolve from randomness to synchrony. In music, some composers went the other way: from sync to un-sync. A phasing-like idea, long before minimalism, already present in Beethoven’s Sonatas. Maybe art’s tendency to defy form.

What are multi-agent systems with reinforcement learning, and why does "diversity" help them develop "collective intelligence"? This Cambridge PhD thesis by M.Bettini offers a clear and insightful overview. (Open access - download from): repository.cam.ac.uk/items/7d168345

“L’io, io!… il più lurido di tutti i pronomi!… I pronomi! Sono i pidocchi del pensiero. Quando il pensiero ha i pidocchi, si gratta come tutti quelli che hanno i pidocchi… e nelle unghie, allora… ci ritrova i pronomi: i pronomi di persona.” [Carlo Emilio Gadda] (h/t #SergioSchneider)

In un capitolo del suo "A spasso con il cane Luna" (lettura consigliatissima) @gVallortigara ci racconta dell'arcipelago St. Kilda "un luogo ai confini del mondo". Come ha scritto Borges ("le rovine circolari" ) "Quel cerchio è un tempio che gli antichi incendi divorarono..."

In August 2010, Claudio Abbado conducted Mahler’s 9th in Lucerne. After the final note, the audience held its breath: 2'24" of a haunting and spooky silence—perhaps the longest ever after a live concert. Listen from 5:20 to 7:44 and enjoy the silence!😳 youtu.be/81AFdWXLNCU?...

The two blue and the red particles have opposite charges. Starting from the vertices of an equilateral triangle they move under Coulomb forces: blue-blue repulsion, red-blue attraction… The resulting motion is beautifully unpredictable. More on youtu.be/nqAcMm2o-kk
