Book Description
HISTORICAL PRELUDE Ettore Majorana's fame solidly rests on testimonies like the following, from the evocative pen of Giuseppe Cocconi. At the request of Edoardo Amaldi, he wrote from CERN (July 18, 1965): "In January 1938, after having just graduated, I was invited, essen tially by you, to come to the Institute of Physics at the University in Rome for six months as a teaching assistant, and once I was there I would have the good fortune of joining Fermi, Bernardini (who had been given a chair at Camerino a few months earlier) and Ageno (he, too, a new graduate), in the research of the products of disintegration of /-L "mesons" (at that time called mesotrons or yukons), which are produced by cosmic rays [ . . . ] "It was actually while I was staying with Fermi in the small laboratory on the second floor, absorbed in our work, with Fermi working with a piece of Wilson's chamber (which would help to reveal mesons at the end of their range) on a lathe and me constructing a jalopy for the illumination of the chamber, using the flash produced by the explosion of an aluminum ribbon short circuited on a battery, that Ettore Majorana came in search of Fermi. I was introduced to him and we exchanged few words. A dark face. And that was it.

Book Description
On the night of March 26, 1938, nuclear physicist Ettore Majorana boarded a ship, cash and passport in hand. He was never seen again. In A Brilliant Darkness, theoretical physicist Joo Magueijo tells the story of Majorana and his research group, ''the Via Panisperna Boys,'' who discovered atomic fission in 1934. As Majorana, the most brilliant of the group, began to realize the implications of what they had found, he became increasingly unstable. Did he commit suicide that night in Palermo? Was he kidnapped? Did he stage his own death? A Brilliant Darkness chronicles Majorana's invaluable contributions to science - including his major discovery, the Majorana neutrino - while revealing the truth behind his fascinating and tragic life.

Book Description
A century after his birth, Ettore Majorana is rightfully considered one of the greatest physicists of the first half of the last century. With this volume the Italian Physical Society presents a collection of Ettore Majorana's scientific papers in the original language and, for the first time -- with three exceptions -- translated into English. Each paper is then followed by a comment in English of an expert in the scientific field.

Book Description
Eighty years ago, Ettore Majorana, a brilliant student of Enrico Fermi, disappeared under mysterious circumstances while going by ship from Palermo to Naples. How is it possible that the most talented physicist of his generation vanished without leaving a trace? It has long been speculated that Majorana decided to abandon physics, disappearing because he had precociously realized that nuclear fission would inevitably lead to the atomic bomb. This book advances a different hypothesis. Through a careful analysis of Majorana's article "The Value of Statistical Laws in Physics and Social Sciences," which shows how in quantum physics reality is dissolved into probability, and in dialogue with Simone Weil's considerations on the topic, Giorgio Agamben suggests that, by disappearing into thin air, Majorana turned his very person into an exemplary cipher of the status of the real in our probabilistic universe. In so doing, the physicist posed a question to science that is still awaiting an answer: What is Real?

Book Description
This book presents in full the work of the Italian theoretical physicist Ettore Majorana and explains its impacts, which are still being felt. It opens with a contribution by A. Zichichi that considers in depth the scientific genius of Majorana. This introductory chapter is followed, in chronological order, by the eleven scientific papers by this great scientist, in most cases translated into English for the first time. Each paper is accompanied by a comment from an expert in the field in question. Although very few in number, Majorana's papers constitute a heritage of undeniable value and extraordinary scientific meaning, since they laid the foundations for research fields that remain topical today. With this in mind, two additional contributions on ongoing developments in these research fields are included: one on neutrino physics and the other on Majorana fermions in condensed matter. The volume closes with a note on Majorana's life until his ill-fated disappearance.

Book Description
'The Majorana Case is beautifully written, with a pleasant style, and concatenates a great deal of material. A text that could only be written by those who know the life and work of Ettore Majorana very well, as Prof Recami. The book traces the extraordinary life of Ettore Majorana — through his letters, documents and several testimonies from his friends and family members. What makes it more fascinating is that the author presented it also as a detective-story, by exploring his mysterious disappearance at young age. The personal testimonies also give to the book a welcome surplus. The Majorana Case, therefore, is both a pleasant biography and a mystery book.'Contemporary PhysicsEttore Majorana was born in the Sicilian city of Catania. He joined Enrico Fermi's 'Via Panisperna boys' at an early age and was part of the team who first discovered the slow neutrons (the research that would lead to the nuclear reactor and eventually, the atomic bomb). Enrico Fermi considered him one of brightest scientists, comparable to Galileo and Newton.On March 25, 1938, Ettore Majorana mysteriously disappeared at 31. When the author moved to the University of Catania, Sicily, from Milan University back in 1968, he soon discovered important documents pertaining to Majorana's life and works. Together with his own investigative materials and full cooperation from Majorana's family members, he published a book on his disappearance in Italian (after having helped the famous Italian writer, Leonardo Sciascia, to write down his known Essay, by supplying him with copy of some of the discovered documents). Recami's book was entitled Il Caso Majorana — Epistolario, Documenti, Testimonianze and when it first appeared in Italy, it drew interest from all the major newspapers, publications and TVs & broadcast media.Even after his disappearance, Ettore Majorana's name appeared in many areas of frontier physics research, ranging from elementary particle physics to applied condensed matter, to mathematical physics, and more. His long lasting contributions is a testimony of his brilliance and farsightedness and has continued to draw interest from scientists not only in Italy, but from all over world until today.An English version of the original is very appropriate at this juncture, when more and more scholars in the world are getting convinced that he was really a genius 'like Galileo and Newton'. This book traces the extraordinary life of Ettore Majorana — through his letters, documents and testimonies from his friends and family members. What makes this book more fascinating (as a detective-story too) is his mysterious disappearance at young age. This book, therefore, is both a biography and a mystery book.

Book Description
In this XVII Course of the International School of Cosmology and Gravitation devoted to "ADVANCES IN THE INTERPLAY BETWEEN QUANTUM AND GRAVITY PHYSICS" we have considered different aspects of the influence of gravity on quantum systems. In order to achieve this aim, in many lectures, seminars and discussions we have strengthened the interplay between gravity and quantum systems starting from the situation in the early universe based on astrophysical observations, up to the earthly based experiments with atom interferometry for probing the structure of space-time. Thus we have had timely lectures on the quantum field and horizon of a black hole including reviews of the problem of black holes thermodynamics and entropy, quantum information, quantum black holes, quantum evaporation and Hawking radiation, recent advances in stockastic gravity. We have also discussed quantum fluctuations in inflationary universe, quantum effects and reheating after inflation, and superplanckian energies in Hawking radiation. In this regard the subject of spinors in purely affine space-time and Dirac matter according to Weyl in the generalized theory of gravitation were developed . The dualism between space-time and matter has been deeply analyzed in order to see why, for general relativity, this is an obstacle for quantization of the theory. Also canonical Gravity and Mach's principle, torsion and curvature as commutator for Quantum Gravity and Dirac Geometry of real space-time were analysed, together with the problem of 5-Dimensional Projective Unified Field theory and Multidimensional Gravity and Cosmology.

Book Description
Quantum measurement (Le., a measurement which is sufficiently precise for quantum effects to be essential) was always one of the most impor tant points in quantum mechanics because it most evidently revealed the difference between quantum and classical physics. Now quantum measure ment is again under active investigation, first of all because of the practical necessity of dealing with highly precise and complicated measurements. The nature of quantum measurement has become understood much bet ter during this new period of activity, the understanding being expressed by the concept of decoherence. This term means a physical process lead ing from a pure quantum state (wave function) of the system prior to the measurement to its state after the measurement which includes classical elements. More concretely, decoherence occurs as a result of the entangle ment of the measured system with its environment and results in the loss of phase relations between components of the wave function of the measured system. Decoherence is essentially nothing else than quantum measurement, but considered from the point of view of its physical mechanism and resolved in time. The present book is devoted to the two concepts of quantum measure ment and decoherence and to their interrelation, especially in the context of continuous quantum measurement.
