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.
The metaphor of Ambient Intelligence (AmI) tries to picture a
vision of the future where all of us will be surrounded by
'intelligent' electronic environments, and this ambient has claims
to being sensitive and responsive to our needs. Ambient
Intelligence without invasion of privacy represents a long-term
vision for the EU Information Society Technologies Research
programme. A strong multi-disciplinary and collaborative approach
is a key requirement for large-scale technology innovation and the
development of effective applications. Up to now, most of the books
and papers related to AmI focus their analysis on the technology
potential only. An important feature of this volume is the link
between the technology - through the concepts of ubiquitous
computing and intelligent interface - and the human experience of
interacting in the world - through a neuro-psychological vision
centred on the concept of 'presence'. Presence - the sense of being
there - is the experience of projecting one's mind through media to
other places, people and designed environments.The combination of
recent discoveries in cognitive neuroscience - which make it
possible to acquire a better understanding of the human aspects of
presence, and the breakthroughs at the level of the enabling
technologies make it increasingly possible to build novel systems
based on this understanding. The goal of this volume is to assess
the technologies and processes that are behind the AmI vision, in
order to help the development of state-of-the-art applications.
More in detail, this volume aims at supporting researchers and
scientists, interested in the understanding and exploiting the
potential of AmI.

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.

This book focusses on basic science, but it also addresses engineers interested in new materials. Experiments on metal clusters are reviewed in two long pedagogically written articles. The theoretical courses cover three main domains: (1) electronic properties of metallic clusters and nanostructures, (2) phases and phase changes of small systems, and (3) chemical processes in nanoscale systems. Furthermore, interested readers, researchers as well as graduate students will find articles on density functional theory, magnetic properties of clusters, and computer simulations of cluster dynamics. In addition, the book addresses chemical processes, pairing correlation effects and also biological systems.
Christians are increasingly interested in justice issues. Relief
and development work are important, but beyond that is a need for
advocacy. This book shows how transforming systems and structures
results in lasting change, providing theological rationale and
strategies of action for evangelicals passionate about justice.
Each of the authors contributes both academic expertise and
extensive practical experience to help readers debate, discuss, and
discern more fully the call to evangelical advocacy. They also
guide readers into prayerful, faithful, and wise processes of
advocacy, especially in relation to addressing poverty.
