Book Description
This book collects recent results in systems whose evolutions are dominated by fluctuations, driven systems in which the way to dissipate driving forces is relevant, and systems in which disorder induces highly non-trivial dynamics leading naturally to questions of computational complexity. Topics of the 14 papers include multiplicative noise in non-equilibrium phase transitions, the stochastic population dynamics of spiking neurons, anomalous velocity distributions in elastic Maxwell gases, universality issues in surface kinetic roughening of thin solid films, and multi-state neural networks based upon spin glasses. Some of the chapters have appeared in the arXiv.org database. No information is given about the authors. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).

Book Description
Numa linguagem simples, as origens e evolução das idéias da Física são apresentadas, partindo-se das noções iniciais introduzidas pelos filósofos gregos, até as concepções atuais da Teoria da Relatividade e da Física Quântica.

Book Description
A presente obra é uma coletânea de trabalhos que exploram aspectos da história dessa teoria cientifica, desde sua criação aos desenvolvimentos ulteriores, incluindo a controvérsia sobre os seus fundamentos e sobre suas implicações filosóficas e culturais. Discute também problemas relacionados à pesquisa sobre o ensino e a difusão cultural dessa teoria, bem como os usos, e abusos, que ai podem aparecer.

Book Description
Uma viagem profundamente instrutiva pela vida e obra de cientistas cujas descobertas revolucionaram a física do século XX e transformaram nosso conhecimento do universo. Tomando como ponto de partida Isaac Newton, que estabeleceu as bases da física moderna, o autor percorre a trajetória de Albert Einstein, que abalou os fundamentos de todas as ciências com sua teoria da relatividade, Max Planck, pai da física quântica, Niels Bohr, criador do primeiro modelo preciso do átomo – além de Ernest Rutherford, Werner Heisenberg, Richard Feynman e Murray Gell- Mann – para delinear um retrato completo da física moderna e de seus pioneiros.

Book Description
This book investigates Hermann Weyl’s work on the problem of space from the early 1920s onwards. It presents new material and opens the philosophical problem of space anew, crossing the disciplines of mathematics, history of science and philosophy. With a Kantian starting point Weyl asks: among all the infinitely many conceivable metrical spaces, which one applies to the physical world? In agreement with general relativity, Weyl acknowledges that the metric can quantitatively vary with the physical situation. Despite this freedom, Weyl “deduces”, with group-theoretical technicalities, that there is only one “kind” of legitimate metric. This construction was then decisive for the development of gauge theories. Nevertheless, the question of the foundations of the metric of physical theories is only a piece of a wider epistemological problem. Contributing authors mark out the double trajectory that goes through Weyl’s texts, from natural science to philosophy and conversely, always through the mediation of mathematics. Readers may trace the philosophical tradition to which Weyl refers and by which he is inspired (Kant, Husserl, Fichte, Leibniz, Becker etc.), and explore the mathematical tradition (Riemann, Helmholtz, Lie, Klein) that permitted Weyl to elaborate and solve his mathematical problem of space. Furthermore, this volume analyzes the role of the interlocutors with whom Weyl discussed the nature of physical space (Einstein, Cartan, De Sitter, Schrödinger, Eddington). This volume features the work of top specialists and will appeal to postgraduates and scholars in philosophy, the history of science, mathematics, or physics.

Book Description
This book provides guidelines for evaluating the contribution of Spiritism to health. It is based on conferences presented in six European countries in October 2002 on the following themes: Principles of Spiritist Medicine and Bioethics, Perispirit, The Reincarnation Process, and Human Cloning. This book emphasizes the integral being: Spirit-matter, the complexity of subtle bodies, new concepts of health and illnesses, anamnesis and pathogenesis, and the integration of Spirituality into medical treatments highlighting the healing power of faith and love. It answers serious questions about Human Cloning, such as: "is it acceptable to clone people or to produce human embryos and then use them as a source for various tissues?". This book proposes a definitive union between Health and Spirituality in response to man's aspirations and scientific pursuits. What is the contribution of Spiritism to Medicine? Should people be cloned? Should human embryos be produced? This book answer these questions and many others, presenting topics such as •Principles of Spiritist Medicine and Bioethics •Human Cloning •Constitution of the Perispirit With them emerges an integral view of the Human Being: Spirit-matter. In pathological cases, it relates biological, social and psychological factors, but above all, the spiritual ones; in processes of cure, it mobilizes all available resources as well as those which are linked to the soul and its essence: faith, prayer and love.

Book Description
Parte considerável do atual estágio tecnológico é consequência direta da revolução científica ocorrida no final do século 19. Na última década daquele século, a humanidade testemunhou uma extraordinária ebulição em várias áreas do conhecimento.É nesse período que a ciência e a tecnologia dão um salto quantitativo e qualitativo jamais visto na história do pensamento humano. Para se ter uma ideia da dimensão dessa rápida evolução, basta ter em mente que em 1895 o grande público ainda não desfrutava dos seguintes artefatos: telefone, lâmpada incandescente, automóvel a gasolina e avião. Todos já haviam sido inventados, mas não estavam disponíveis, a não ser em limitadíssima escala. Portanto, que a sociedade de 1895 vivia trevas.
