It's the 5 of October 2021, at the end of incredible year for Italy, for better or for worse. It's not over yet though. That day, in fact, Sweet at the bottom, in Stockholm. Along with climate physicist Hasselmann and Manabe (a first for the field), the Academy gives half of the Nobel Prize 2021 to the Italian physicist Giorgio Parisi . The motivation for the assignment is "for the discovery of the interaction between disorder and fluctuations in physical systems from the atomic scale to [...]
The story of the Nobel laureate Salvatore Luria, a passionate scientist!
Finally! It was time! Only he was missing. Even the kilogram, from the 20 May, has an acceptable definition. Let me be clear: you don't have to throw away your scales. A kilo remains a kilo, but now it's more fancy. Until a few days ago, what was a kilogram? It was The Mass (mass, not the weight, remember, They are different) of a particular Platinum-Iridium cylinder deposited at the International Bureau of Weights and Measures in France. The matter that surrounds us, however, has the bad habit of changing: some molecules can detach, it can simply oxidize, change shape thanks to some cosmic ray. Small variations of which, of [...]
La fisica governa tutto ciò che ci circonda, dalla luce alla caduta dei corpi, dall'elettricità al Wi-Fi. Conoscere le leggi fondamentali della fisica ha permesso all'uomo di fare enormi progressi tecnologici, ed è tuttora uno dei campi di maggiore ed intenso sviluppo applicativo. A che punto siamo oggi? Quali sono le scoperte e le applicazioni della fisica che cambieranno il mondo nei prossimi anni? Un viaggio alla scoperta della fisica moderna e delle sue applicazioni, ad opera di Valentina Cicero. Vi aspettiamo al quinto appuntamento con i Café Minerva, in compagnia di un ottimo aperitivo presso Scuderia - FF Urban [...]
For modern science, the realization of cold fusion would be the equivalent of the philosopher's stone for the ancient alchemists, or the tool by which they claimed to be able to transform poor metals into gold and silver. To the present day, the real challenge is to fuse two atoms and get a bigger one, thus achieving nuclear fusion. Andrea Rossi, inventore dell’Energy Catalyzer (E-cat) claims to have succeeded and promises, thanks to its device, to wipe out all of humanity's energy problems in one fell swoop. Illustration depicting an alchemist at work. L’E-cat sarebbe in grado di trasformare Idrogeno [...]
