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.

Teaching electric current.
In the Drude model, electrons move like little balls, bouncing off ions at random.
With an applied electric field they drift, on average, and create a current.

Why does the buttered toast (almost) always land butter-side down?
Is it Murphy’s Law?
Is it the universe making fun of you?
No, it's just the laws physics, babe!
Robert Matthews (winner of the Ig Nobel Prize for physics in 1996) took the problem seriously...

«È sparito anche il vuoto» è una splendida (ma poco nota) poesia di #EugenioMontale. È stata usata come epigrafe dal fisico #GuidoTonelli in “L’eleganza del vuoto”. Dagli antichi filosofi, alla teoria quantistica dei campi.

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!😳

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.

New paper: "Large Language Models and Emergence: A Complex Systems Perspective" (D. Krakauer, J. Krakauer, M. Mitchell).
We look at claims of "emergent capabilities" & "emergent intelligence" in LLMs from the perspective of what emergence means in complexity science.

Consider an equilateral triangle and place three equal masses at the 3 vertices.
Are there points in the plane in which the net gravitational field is zero? (equilibrium pts or sort of Lagrangian pts)
The centroid? Yes! But there are 3 other equilibrium points! 😳

During a gravitational elliptic orbit, the path traced by tip of the velocity vectors (collected together as to have a common origin) is a circle!!! 😲
In general, the curve traced by the tip of the velocity vector of a moving body is called "Hodograph".
