I’ll give a public non-technical talk, in the beautiful Sala del Romanino at the Eremitani Museum
In 40 minutes, we’ll travel from 3340 B.C. to 2100, exploring how demons, oracles & models have helped humans make sense of the world. Join!

Not the best conditions for taking pics, but I tried anyway. I can confirm conditions were not good: their blue lights got destroyed by interference with the moon ones.

Axelrod’s rules remind us: fairness, reciprocity and humility often outcompete envy and cleverness.
In complexity, often simplicity wins.

An entity knowing every particle and law in the universe: able to predict, with perfect accuracy, both past & future.
Laplace's demon dreamed of total knowledge.
But quantum mechanics and complexity awoke us: the world is not a clockwork!
It's an intricate web of uncertainty.

Comet Lemmon! 💫
Nice to read again the history of the attempts in the last weeks. Now, I am almost satisfied with the result: still something to fix, though.

I could not resist: perfect sky after 2 rainy days; no clouds now; just in plain sight from my backyard.
Fingers crossed @scrutacieli.bsky.social

Where will this lead? Are we safe? Should we flatten the curve before it spreads?
Asking for a friend who’' extremely concerned about alien invasion, especially after recent rumors on 3I/ATLAS.

But since it had a beginning and is expanding, most starlight hasn’t reached us yet, or has been redshifted beyond the visible spectrum

a trillion places where chemistry might have transitioned to biology.
With numbers like these, believing we’re the only ones feels… just statistically unwise.

That much sand would fill ~1.5 million buildings like that. That's an insane number of 🏢
If you laid them out side by side, their footprints would cover about 1 500 km²: roughly the size of Greater London.
A whole London of planetary sand!

How much space would all 10²¹ grains take up?
Assuming spherical grains with 1mm diameter, this is about 523 km³ of solid sand: the volume of all those worlds combined into one cosmic sandbox.
