The remarkable recent discovery of the Higgs boson at the CERN Large Hadron Collider completed the Standard Model of particle physics and has paved the way for understanding the physics which may lie beyond it. String/M theory has emerged as a broad framework for describing a plethora of diverse physical systems, which includes condensed matter systems, gravitational systems as well as elementary particle physics interactions. If string/M theory is to be considered as a candidate theory of Nature, it must contain an effectively four-dimensional universe among its solutions that is indistinguishable from our own. In these solutions, the extra dimensions of string/M theory are “compactified” on tiny scales which are often comparable to the Planck length. String phenomenology is the branch of string/M theory that studies such solutions, relates their properties to data, and aims to answer many of the outstanding questions of particle physics beyond the Standard Model. This book contains perspectives on string phenomenology from some of the leading experts in the field. Contributions will range from pedagogical general overviews and perspectives to more technical reviews. We hope that the reader will get a sense of the significant progress that has been made in the field in recent years (e.g. in the topic of moduli stabilization) as well as the topics currently being researched, outstanding problems and some perspectives for the future.

Since the discovery of neutrino oscillations neutrino physics has become an interesting field of research in physics. They imply that neutrino must have a small mass and that the neutrinos, coupled to the charged leptons, are mixtures of the mass eigenstates, analogous to the flavor mixing of the quarks. The mixing angles for the quarks are small, but for the leptons two of the mixing angles are large. The masses of the three neutrinos must be very small, less than 1 eV, but from the oscillation experiments we only know the mass differences — the absolute masses are still unknown. Also we do not know, if the masses of the neutrinos are Dirac masses, as the masses of the charged leptons and of the quarks, or whether they are Majorana masses. In this volume, an overview of the present state of research in neutrino physics is given by well-known experimentalists and theorists. The contents — originated from talks and discussions at a recent conference addressing some of the most pressing open questions in neutrino physics — range from the oscillation experiments to CP-violation for leptons, to texture zero mass matrices and to the role of neutrinos in astrophysics and cosmology.

The neutrino is the most fascinating elementary particle due to its elusive nature and outstanding properties that have attracted the interest of generations of physicists since 1930, when it was first postulated by Wolfgang Pauli as a "desperate remedy" to explain the apparent energy violation in the beta decay. Many fundamental discoveries in particle physics had the neutrino involved in one way or another. To date, neutrino physics is still one of the hottest topics of modern particle physics. Key experiments and significant theoretical developments have contributed in building up what we can call now the Standard Model of Neutrino Physics. The aim of the book is to provide graduate students and young researchers a comprehensive tutorial in modern neutrino physics, specially tailored with emphasis on the educational aspects. It provides an overview of the basics and of recent achievements in the field, from both experimental and theoretical points of view.

What is consciousness? Why and when do we have it? Where does it come from, and how does it relate to the lump of squishy grey matter in our heads, or to our material and social worlds? While neuroscientists, philosophers, psychologists, historians, and cultural theorists offer widely different perspectives on these fundamental questions concerning what it is like to be human, most agree that consciousness represents a 'hard problem'.The emergence of consciousness studies as a multidisciplinary discourse addressing these issues has often been associated with rapid advances in neuroscience-perhaps giving the impression that the arts and humanities have arrived late at the debating table. The longer historical view suggests otherwise, but it is probably true that music has been under-represented in accounts of consciousness. Music and Consciousness aims to redress the balance: its twenty essays offer a timely andmulti-faceted contribution to consciousness studies, critically examining some of the existing debates and raising new questions.The collection makes it clear that to understand consciousness we need to do much more than just look at brains: studying music demonstrates that consciousness is as much to do with minds, bodies, culture, and history. Incorporating several chapters that move outside Western philosophical traditions, Music and Consciousness corrects any perception that the study of consciousness is a purely occidental preoccupation. And in addition to what it says about consciousness the volume also presents adistinctive and thought-provoking configuration of new writings about music.

In this introduction to natural-base music theory, Ernst Levy presents the essentials of a comprehensive, consistent theory of harmony developed from tone structure. A Theory of Harmony is a highly original explanation of the harmonic language of the last few centuries, showing the way toward an understanding of diverse styles of music. Basic harmony texts exist, but none supply help to students seeking threads of logic in the field. In a text abundantly illustrated with musical examples, Levy makes clear the few principles that illuminate the natural forces in harmony. He shows that general principles can be successfully extracted from the wealth of examples. This book actually provides a theory of harmony. One of the major musical minds of the twentieth century, Ernst Levy was born in Basel, Switzerland, in 1895. His musical career spanned more than seven decades, from his first public piano performance at age six. A naturalized U.S. citizen, he lived here from 1941 to 1966, teaching at the New England Conservatory, the University of Chicago, Bennington College, the Massachusetts institute of Technology, and Brooklyn College. After his retirement, Levy returned to Switzerland where he continued to compose until his death in 1981. He was an enormously productive composer, with hundreds of works to his credit including symphonies, string quartets, songs in English, French, and German, and music for solo instruments and small ensembles. His piano recordings, particularly of the last Beethoven sonatas and the Liszt sonata, have become collectors’ items. He thought of himself as a successor to Reimann, immediately, and Rameau, more remotely.

Physics World's 'Book of the Year' for 2016 An Entertaining and Enlightening Guide to the Who, What, and Why of String Theory, now also available in an updated reflowable electronic format compatible with mobile devices and e-readers. During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering a highly readable and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics. The author, a theoretical physics professor at the University of Oxford and a leading string theorist, explains what string theory is and where it originated. He describes how string theory fits into physics and why so many physicists and mathematicians find it appealing when working on topics from M-theory to monsters and from cosmology to superconductors.
