This book offers the first comprehensive and authoritative text on the history of physics in Italy’s industrial and financial capital, from the foundation of the University of Milan’s Institute of Physics in 1924 up to the early 1960s, when it moved to its current location. It includes biographies and a historical-scientific analysis of the main research topics investigated by world-renowned physicists such as Aldo Pontremoli, Giovanni Polvani, Giovanni Gentile Jr., Beppo Occhialini, and Piero Caldirola, highlighting their contributions to the development of Italian physics in a national and international context. Further, the book provides a historical perspective on the interplay of physics and politics in Italy during both the Fascist regime and the postwar reconstruction period, which led to the creation of the CISE (Centro Informazioni Studi Esperienze, a research center for applied nuclear physics, funded by private industries) in 1946, and of the Milan division of the National Institute of Nuclear Physics (INFN) in 1951.
Varius is the nomen of the Roman emperor misnamed Elagabalus or Heliogabalus. These are names of the Syrian sun god Elagabal, whose high priest Varius was while emperor. There is no evidence that he was ever so called when alive. Thus named, his posthumous legendary or mythical avatar thrives, in academic prose and popular imagination, as a Semitic monster of cruelty, depravity, fanaticism, mockery and extravagance. Recently, this monster has metamorphosed into an anarchist saint and martyr of gay liberation. This volume explores the historical individual behind Elagabalus and Heliogabalus. Varius was probably born AD 204 in Rome, to Syro-Roman parents linked to the Severan dynasty, and brought up at the imperial court, which spent 208–211 in Britain. After his father’s death in Numidia or Italy, sometime between 214 and 218 Varius went to Syria, where, like a maternal ancestor, he became a priest of Elagabal. In Syria in 217, Macrinus murdered and succeeded the Severan emperor Marcus Aurelius Antoninus, even then known by his nickname, Caracalla. In 218, in a coup against Macrinus, Varius, fourteen, was proclaimed emperor, on the basis of the lie, launched by his grandmother, Caracalla’s aunt, and abetted by his mother, Caracalla’s cousin, that he was Caracalla’s bastard. Varius’ grandmother intended to rule while he reigned. But Varius, now Marcus Aurelius Antoninus, had other ideas. Taking the god Elagabal, a meteorite, to Rome he sought to combine the incompatible personae of Roman emperor and High Priest of Elagabal. He was murdered in 222 before reaching eighteen by his praetorian guards, under the orders of his grandmother and aunt, to make way for his younger, more docile cousin, Alexianus, who reigned as Severus Alexander. Rhetorical invective against Varius was promptly launched to justify his murder. It grew into his mythical or legendary avatar: Elagabalus or Heliogabalus. That avatar came completely to overshadow the historical Varius. This book serves to rescue Varius for history from eighteen centuries spent in fantasy and fiction.

Albert Einstein è universalmente noto per la sua teoria della relatività, con la quale ha mostrato che lo spazio e il tempo non sono immutabili, che il tempo può rallentare e lo spazio diventare curvo. E che l’energia e la materia sono la stessa cosa. La relatività ha cambiato radicalmente il nostro modo di guardare all'universo e non cessa di essere il quadro di riferimento per nuove scoperte (come quella recente delle onde gravitazionali, da lui stesso previste). Ma il contributo di Einstein si estende molto oltre: dalla dimostrazione matematica dell’esistenza delle molecole e di nuovi stati della materia, al principio alla base del laser, fino alla scoperta della legge dell’effetto fotoelettrico, che gli valse il premio Nobel assegnatogli nel 1922.
