I recently read "The order of time" and "Helgoland" by Carlo Rovelli and am very impressed by the rigour, sensitivity and depth with which he treats such fundamental topics. I feel like I learnt a lot. Much more than in the 4 introductions to metaphysics I had read.

Si la quàntica us fascina i us confón, i si sou a València el 19 de novembre, us pot interessar venir a sentir la conversa que mantindré amb Reis Juan a l'Octubre Centre de Cultura Contemporània.

El divendres passat vam inaugurar la Setmana de la Ciència en una conversa, en la meva opinió molt bonica, al Parlament de Catalunya amb Alba Cervera Lierta i Sònia Fernàndez Vidal.
Va ser un honor i un plaer gaudir d'una ocasió així.

By the way, if you'd like to work with me in Barcelona, please get in touch and I can share funding options.
E.g. if you are German and would like to do a PostDoc with me, one can consider the Feodor Lynen fellowship (as I am an Alexander von Humboldt alumnus).

In quantum theory, observables are associated to a vector space, and quantum states to a convex set. Observables can be thought of as questions, such as “Where is the quantum system?" States are something that answers these questions, albeit only probabilistically.

If you could travel through time — any era, any place — when would you go? Come imagine it with us, aboard our 1:1 Victorian time machine, at the upcoming exhibition “The Invention of Time” at Centre Martorell. Opening next Xmas!

What a wonderful book! The age of wonder, by Richard Holmes, tells the story of some early scientists and romantics from around 1800 -- mainly men and mainly British, centered on Joseph Banks, William Herschel and Humphry Davy. Very enjoyable. Thanks @ricardsole.bsky.social for the recommendation 😍

I greatly enjoyed Anaximander, by Carlo Rovelli. "Anaximander opened the doors of Nature", said Pliny.
In the sixth century BCE he proposed that the Earth is a stone floating in the void. And set the ball rolling for scientific instead of mythical cosmogonies.

Last week I was lucky enough to go to Heligoland for a massive quantum shindig.
I asked some incredible physicists & philosophers why we still can't agree on what quantum mechanics tells us about reality ⚛️🧪

For some reason I am loving the experience of teaching Theory of Information at UPF... it is such a beautiful theory. And so recent, not even 100 years old. Many interesting lessons can be drawn from it.

One may think that all the secrets of a matrix can be read from its spectrum (and Jordan blocks, if needed). But this need not be the case. Sometimes you can't even tell if its moments will stay nonnegative forever. Joint work with Andreas Klingler, Joshua Graf & Tim Netzer

I like seeing local physical interactions as the generative grammar of our physical world... For the Ising model, this idea can be made very precise, and prove if and only if theorems that characterize such grammar. Joint work with Tobi Reinhart.

The grammar of the Ising model: a new complexity hierarchy | Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
How complex is an Ising model? Usually, this is measured by the computational complexity of its ground state energy problem. Yet, this complexity measure only distinguishes between planar and non-planar interaction graphs, and thus fails to capture ...
