This is an account of the author's investigation, on behalf of the Canadian government, into the life and ideas of the eccentric genius Nikola Tesla. This is a completely revised and redesigned edition, with a new introduction by the former head of the Tesla Museum, a new chapter and a selection of photographs of Tesla and his work in search of the holy grail of electricity - the transmission of power without loss. As a student in Prague in the 1870s, Tesla "saw" the electric induction motor and patented his discovery, -the first of many inventions whose plans seem to have come to him fully fledged. He worked for the Edison company in Paris before emigrating to the US and battling with Thomas Edison himself to ensure that alternating, rather than direct current, became the standard. He sold his patent in the induction motor for $1 million dollars to George Westinghouse, who used this system for the Niagara Falls Power Project. Moving to Colorado Springs, Tesla worked on resonance, building enormous oscillating towers in experiments which still intrigue today. In later life Tesla became a recluse, bombarding newspapers with eccentric claims, including energy transmissions to other planets. Though he died alone and virtually forgotten, rumours gradually grew that Tesla had made further remarkable discoveries. In an attempt to replicate his experiments, people still build Tesla towers and puzzle over the possible link with low-frequency broadcasts which can supposedly disrupt the weather and affect the human mind.

In the first years after the discovery of radioactivity it became clear that nuclear physics was, by excellence, the science of small quantum systems. Between the fifties and the eighties nuclear physics and elementary particles physics lived their own lives, without much interaction. During this period the basic concepts were defined. Recently, contrary to the specialization law often observed in science, the overlap between nuclear and elementary particle physics has become somewhat blurred.

This Les Houches Summer School was set up with the aim of fighting off the excessive specialization evident in many international meetings, and return to the roots. The twofold challenge of setting up a fruitful exchange between experimentalists and theorists in the first place, and between nuclear and hadronic matter physicists in the second place was successfully met.

The volume presents high quality, up-to-date reviews starting with an account of the birth and first developments of nuclear physics. Further chapters discuss the description of the nuclear structure, the physics of nuclei at very high spin, the existence of super-heavy nuclei as a consequence of shell structure, liquid-gas transition, including both a description and a review of the experimental situation.

Other topics dealt with include the interactions between moderately relativistic heavy ions, the concept of a nucleon dressed by a cloud of pions, the presence of pions in the nucleus, the subnucleonic phenomena in nuclei and quark-gluons deconfinement transition, both theoretical and experimental aspects. Nuclear physics continues to influence many other fields, such as astrophysics, and is also inspired by these same fields. This cross-fertilisation is illustrated by the treatment of neutron stars in one of the final chapters. The last chapter provides an overview of a recent development in which particle and nuclear physicists have cooperated to revitalize an alternative method for nuclear energy production associating high energy production accelerators and sub-critical neutron multiplying assemblies.

Understanding and predicting the Earth's climate system, particularly climate variability and possible human-induced climate change, presents one of the most difficult and urgent challenges in science. Climate scientists worldwide have responded to that challenge over the past decade by creating a wide variety of ever more sophisticated climate models that are beginning to show considerable ability to replicate many aspects of the climate system. At the same time, to fully understand climate change, one also has to look to past climates. For this purpose five eminent scholars who span the disciplines of modeling and observation, including elements of past, present and future climate studies came together at this Les Houches school. They presented a systematic development of each of their respective subjects which provided a comprehensive overview of this vast and complex subject. These core lectures were supplemented by a set of shorter lectures and of seminars.

The first section of this volume corresponds to courses on the cytoskeleton, its various structures and its dynamics, especially during the cell cycle. The reductionist approach is favoured in this field and considerable effort is spent on finding out how these structures are built up from their component molecules, how they grow or decrease in size, how they interact with each other and with other cell components. The second section describes the endo membrane system of a eukaryotic cell and the regulated protein traffic that flows through it. Part III deals with the onset of higher levels of organization. Topics covered include the development of the central nervous system, the role of time in biology and theoretical models to describe biochemical and cellular oscillations. The volume concludes with a reflection on physics and biology and the author shares some of his thoughts on the different ways in which physicists and biologists tackle problems in their respective fields.

In these lectures, I have discussed a number of basic concepts that provide the necessary background to the current studies of star formation. A ?rst partwas dedicatedto illustrate the conceptofa protostar, discussing con- tions and propertiesof the collapseof a molecular core. A secondpart deals with circumstellardisks. Disks areimportantnot only to the processofstar formation itself, but also because they are in all probability the site where planets form. The age range of pre-main-sequence stars coincides with the timescales for the formation of very large planetesimals, the building blocks of planets. Studies ofdisk properties in pre-main-sequencestars ofdi?erent age, located in star-forming regions of di?erent properties, may shed light on the characteristics of planet formation processes. ISO observations can provide important (in some cases, unique) inf- mation on the various stages of the star and planet formation. I have illustrated in detail some examples, when, to my knowledge, ISO data had been reduced and analyzed. Many other programs exist, and will certainly contribute to our understanding of star formation in the near future

This book is written for researchers as well as engineers in an industrial environment. Following a longstanding tradition of the Les Houches Summer Schools, all chapters are pedagogically presented and accessible for graduate students. The book treats 2D and 3D turbulence from the experimental, theoretical and computational points of view. The reader will find, for example, comprehensive accounts of fully developed turbulence experiments, simulating deterministically coherent vortices formation, and statistical prediction of industrial flows, and a very complete review of 2D turbulence. Fundamental concepts like topological fluid dynamics in MHD flows or finite-time singularities of the Burgers, Euler and Navier--Stokes equations complete the volume.

This book, devoted to the study of quantum effects in atomic systems, reviews the state of the art in the fields of Bose--Einstein condensation, quantum information processing, and the problems of propagation of matter waves in complex media. The specific topics include: theory and experiments in Bose--Einstein condensation, theory and experiments on decoherence phenomena in simple quantum systems and the connection to quantum measurement, atom interferometry, quantum computing, multiple scattering problems in atomic physics, quantum and nonlinear optics in a photonic band gap and quantum chaos and atomic physics. Pedagogical in style, the articles address PhD students as well as researchers.

This book reviews the interconnection of cosmology and particle physics over the last decade. It provides introductory courses in supersymmetry, superstring and M-theory, responding to an increasing interest to evaluate the cosmological consequences of these theories. Based on a series of extended courses providing an introduction to the physics of the very early universe, in the light of the most recent advances in our understanding of the fundamental interactions, it reviews all the classical issues (inflation, primordial fluctuations, dark matter, baryogenesis), but also introduces the most recent ideas about what happened at the Big Bang, and before.

Originally published in 1979. This reprints the revised and expanded edition of 1996. In this volume, physicists, biologists and chemists, who have been involved in some of the most exciting discoveries in modern scientific thought explore issues which have shaped modern physics and which hint at what may form the next scientific revolution. The major issues discussed are the understanding of time and space, quantum and relativity theories and recent attempts to unite them and related questions in theoretical biology.

In Science, Order and Creativity, David Bohm and F. David Peat argue that science has lost its way in recent years and needs to go beyond a narrow and fragmented view of nature and embrace a wider holistic view that restores the importance of creativity and communication for all humanity - not just scientists.
The result of a close collaboration by one of the 20th century's greatest physicists and thinkers, David Bohm, with leading science writer F. David Peat, provides a rare combination of profound reflection and clear exposition that can be appreciated by anyone concerned with science and its importance in our lives.
This new edition includes a new preface and an extended additional chapter by Peat which draws upon further discussions with David Bohm before the latter's death in 1992. A fascinating diagnosis and considered proposal for a cure for science's ills, it is also very accessible entry point to the work of David Bohm. Bohm and Peat contend that science has lost its bearings in the last century in favour of a narrow, abstracted, fragmented approach to nature and reality. Tracing the history of science, Bohm and Peat offer intriguing new insights into how scientific theories come into being, how to eliminate blocks of creativity and how science can lead to a deeper understanding of society, the human condition and the human mind itself.

The Humanities Through the Arts examines how values are revealed in the arts while keeping in mind a basic question: "What is art?" It binds us together as a people by revealing the most important values of our culture. This program's genre-based approach offers students the opportunity to understand the relationship of the arts to human values by examining, in-depth, each of the major artistic media: painting, sculpture, architecture, literature, theater, music, dance, photography, cinema, and television and video art. Subject matter, form, and content in each of the arts supply the framework for careful analysis. All of this is achieved with an exceptionally vivid and complete illustration program. The wide range of opportunities for criticism and analysis helps the reader synthesize the complexities of the arts and their interaction with values of many kinds. The text contains detailed discussion and interactive responses to the problems inherent in a close study of the arts and values of our time.
