##### An extract of the debate on What is art?

We held a debate on What is art? in Palau Macaya (Barcelona) on June 14th and 15th, 2023 (in Catalan). A curated extract of the debate can be found here and the entire debate here. A monograph was published in La Maleta de Portbou, Nr. 61 (2023).

##### The introduction to my Habilitation

My Habilitation (submitted in 2022) sheds some (metaphorical) light on some aspects of quantum theory: on relating the whole to the parts, on quantum magic squares, and on shadows of infinity. The theme from the whole to the parts revolves around eight questions, whose main actresses are non-commutativity, the tensor product, positive elements and complex numbers.

##### The mathematical magic hiding in the Sagrada Familia

I tried to share some of the magic of quantum theory, of magic squares and of quantum magic squares here. How beautiful is this sculpture (by Subirachs) at the Sagrada Familia? Not to speak of the Sagrada Familia itself... I should translate the article soon.
