Ettore Majorana (1906-1938) passed through theoretical physics like a meteor. In fact, his official fundamental papers are just nine. They were all written in the short period from 1928 to 1933. They are audacious and strongly beautiful works which impose themselves over and over again on any generation of theoretical physicists as the paradigm of a style able to fuse - by a singular critical thinking - both the attention for the experimental data and the freedom of theoretical reasoning in a mathematical formulation reaching the essential core of the problem.
During the last years, a new kind of interest for Majorana legacy has grown. The widening of theoretical physics’ spheres has favoured an increasing awareness of the deep connection between symmetries and interactions, and a renewed conception of theoretical physics and mathematics relation. How Roger Penrose effectively wrote, the deeper our understanding of physical laws becomes, the more we penetrate into the abstract world of mathematical concepts. Which thing allowed the new generation of theorists to get out new topics from Majorana work and to approach theoretical physics according to what we can define as the Majorana style.
This anthology has been thought not only as an owed celebrative act, but especially as a meeting of researchers on some presently debated aspects in physics in Majorana spirit.
Di Renzo Editore diventa internazionale
Con la pubblicazione di What is Time? What is Space? di Carlo Rovelli e Roman Art, An American’s View di Richard Brilliant, Di Renzo Editore si apre al mercato internazionale.
I libri sono la versione inglese di due best-seller della collana I DIALOGHI, il cui successo si spera di ripetere. Le nuove pubblicazioni sono dirette in particolare al mercato anglosassone e nord-americano e riguarderanno soprattutto i dialoghi della sezione scienza. Tra questi Dennis Sciama, Jacob Bekenstein e Federico Capasso, che dovrebbero arrivare alle stampe tra il settembre o l’ottobre prossimo.
Non si tratta di una novità per Di Renzo Editore che, considerata la grande mole di autori stranieri di spicco, aveva già tentato l’esperimento con il libro di Paul Davies, Un solo universo o infiniti universi?, le cui versioni inglese e italiana avevano visto la luce in contemporanea.
In programma anche la traduzione di un'opera di Giuseppe Arcidiacono (Projective Relativity Cosmology and Gravitation), autore di spicco della collana “Arcobaleno”.
“A novel image of the world is taking shape in fundamental physics: a world without time and without space. Time and space as we know them will disappear from the scientific picture of the world, in the same way in which the centre of the universe did.”
In this agile text, derived from a long interview, Carlo Rovelli, theoretical physicists and pioneer of modern quantum gravity, describes his personal and intellectual journey, starting from the rebellion of his young years and the discovery of the “enchanting adventure” of theoretical research, till the vertiginous hypotheses of today’s physics. In a simple language, Rovelli introduces us to a “space” made of grains, a “time” which is the result of our ignorance, to hot black holes and how to think about the beginning of the universe.
But he also discusses the value, the risks, and the fascination of this quest. Science, for Rovelli, is a continuous exploration of new ways of thinking the world, the desire of looking “beyond the hill” and seeing the world always with new eyes, the choice of never giving up dreams.
Carlo Rovelli is Professor of Theoretical Physics at the Université de la Méditerranée in
