From 23 July to 10 August 1977 a group of 125 physicists from 72 laboratories of 20 countries met in Erice to attend the 15th Course of the International School of Subnuclear Physics. The countries represented at the School were: Belgium, Bulgaria, Denmark, Federal Republic of Germany, Finland, France, Hungary, Ireland, Israel, Italy, Japan, the Netherlands, Norway, Poland, Sweden, Switzerland, the United Kingdom, the United States of America and Venezuela. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technologi cal Research (MRST) , the North Atlantic Treaty Organization (NATO), the Regional Sicilian Government (ERS) and ...

“Blockchains will matter crucially; this book, beautifully and clearly written for a wide audience, powerfully demonstrates how.” —Lawrence Lessig “Attempts to do for blockchain what the likes of Lawrence Lessig and Tim Wu did for the Internet and cyberspace—explain how a new technology will upend the current legal and social order... Blockchain and the Law is not just a theoretical guide. It’s also a moral one.” —Fortune Bitcoin has been hailed as an Internet marvel and decried as the preferred transaction vehicle for criminals. It has left nearly everyone without a computer science degree confused: how do you “mine” money from ones and zeros? The answer lies in a techno...
Un gioco con i pensieri più semplici presenti nella mente di ogni essere umano.L'autore parte dalla celebre affermazione di Socrate: "So che non so nulla". E si domanda: "Che cosa sa chi dice di sapere di non sapere nulla?". Tenta di rispondere come se si trovasse di fronte a un semplice gioco di enigmistica o indovinello: senza ricorrere a nessuna nozione ottenuta da altri libri o discorsi svolti in altre sedi. Nel tentativo di rispondere egli crede di aver scoperto che in realtà: "Vi sono molte cose che tutti sanno senza sapere che le sanno". Le più importanti di queste cose sono definite "Il minimo comune pensare" o "il minimo comune sapere". Un sapere quindi "universale": valido in ogni tempo, in ogni luogo, per qualsiasi persona, in qualsiasi condizione personale o sociale essa si trovi. L'autore si azzarda così ad enunciare questa tesi temeraria. Esiste "un modo di pensare il mondo", una "filosofia": presente nella mente di tutti, uguale per tutti in tutti i tempi e in tutti i luoghi; capito da tutti; che permette a tutti di capire tutti. Il lettore viene ora invitato a giocare per verificare egli stesso se l'autore ha dato all'indovinello la risposta esatta.
This graduate/research level book describes our present knowledge of protons and neutrons, the particles which make up the nucleus of the atom. Experiments using high energy electrons, muons and neutrinos reveal the proton as being made up of point-like constituents, quarks. The strong forces which bind the quarks together are described in terms of the modern theory of quantum chromodynamics (QCD), the â€~glue' binding the quarks being mediated by new constituents called gluons. Larger and new particle accelerators probe the interactions between quarks and gluons at shorter distances. The understanding of this detailed substructure and of the fundamental forces responsible is one of the keys to unravelling the physics of the structure of matter. This book will be of interest to all theoretical and experimental particle physicists.
For the Galvani Bicentenary Celebrations, the University of Bologna and its Academy of Sciences singled out subnuclear physics as the field of scientific research to be associated with this important event, as it would best illustrate, for the new generation of students, the challenge inherent in fundamental sciences. Subnuclear physics has represented, ever since it was born, the new frontiers of Galilean science. In his opening lecture delivered on the first day of the new academic year, Professor Antonino Zichichi analytically reviewed the basic conceptual developments and main discoveries achieved in subnuclear physics since its birth in the 20th century. Given the importance of this field of fundamental research, Professor Zichichi was invited to expand the contents of his lecture into a book, and the outcome is this volume.
