Cientista e autor multifacetado, largamente conhecido como um dos maiores divulgadores da ciência do século XX, Sagan utilizou os meios de comunicação mais poderosos de seu tempo para divulgar e advogar sua visão pessoal da ciência. Ao mesmo tempo em que buscou tornar o conhecimento científico compreensível e atraente para um vasto público não especializado, Sagan também procurou fazer uma defesa apaixonada da ciência, de seus métodos e de sua visão de mundo. A dissertação procura interrogar a obra de divulgação de Sagan do ponto de vista da epistemologia, filosofia e história da ciência: que visão de ciência foi propagada por Sagan? Que posicionamento epistemológico embasou sua defesa da ciência como forma privilegiada de conhecimento em meio a outros discursos possíveis sobre a realidade? Qual era exatamente a sua visão sobre o progresso da ciência? Como se comparam as ideias de Sagan frente às questões da filosofia da ciência contemporânea em torno do chamado realismo científico? Espera-se que o trabalho abra uma trilha para divulgadores e educadores questionarem uma obra de excelente capacidade didática para a formação do pensamento crítico de jovens e adolescentes e que as respostas aqui esboçadas possam servir de ponto de partida para futuras investigações no campo da filosofia da ciência e áreas correlatas / Abstract: The American astronomer Carl Sagan (1934-1996) is widely known as one of the most influential and successful popularizers of science of all times, managing skillfully the printed and electronic media to make scientific knowledge understandable to a vast audience in a simple and attractive way, while passionately advocating scientific method and worldview. This dissertation examines Sagan's popularization works from the point of view of epistemology, philosophy and the history of science, in the search for answers to a set of questions of interest to all these areas, and also to science writing, such as: What was, both in broad outline and in certain specific details, the conception of science advocated by Sagan? What were his epistemological arguments for defending science as a privileged form of knowledge? Was he aware of the issue - much-debated among contemporary philosophers of science - of the so-called scientific realism? What exactly was his view on the progress of science? It is hoped that the tentative answers here offered may not only provide a useful material for science popularizers and educators, but also serve as starting points for further research in philosophy of science and related academic areas / Mestrado / Divulgação Científica e Cultural / Mestre em Divulgação Científica e Cultural

Comment s’articulent, autour des rapports entre l’homme et la nature, les pratiques scientifiques du naturaliste et du géographe, une pensée politique s’étendant du libéralisme à l’anarchisme et un style d’écrivain ? C’est la question que posent, singulièrement à la forme de l’essai, les œuvres d’Alexander von Humboldt (1769-1859), de Henry David Thoreau (1817-1862) et d’Élisée Reclus (1830-1905). Dans un large XIXème siècle à envisager comme période révolutionnaire marquée par l’effacement des terræ incognitæ, le recul de la nature « sauvage » et les soubresauts économiques et politiques (Révolution Industrielle et révolutions politiques faisant se succéder les régimes), ces figures qu’il faut relire comme d’authentiques écrivains allient au sein d’une politique de la nature la géographie de la Terre à celle de l’Homme, et leurs expériences personnelles de la nature (du voyage d’exploration à l’habitat) à une pensée de la communauté allant et venant de l’individu à l’humanité, du micro- au macrocosme. Héritiers des Lumières luttant contre l’esclavage, le despotisme et le colonialisme, qu’ils documentent, ces essayistes qui refusent de laisser la science aux mains d’une caste positiviste et ethnocentriste sont les vulgarisateurs et les prophètes d’une démocratie littéraire en construction. Ils sont les pionniers d’une exploration moderne des rapports entre écriture et connaissance, les témoins essentiels d’une différenciation des savoirs que leur pratique littéraire universaliste entend conjurer. Tout l’enjeu consiste à perpétuer une approche de la nature comme un ensemble (cosmos) au moment même où elle se trouve, en tant qu’objet, divisée entre création littéraire et savoir savant. A l’aube de l’écologie littéraire et dans cette description d’un monde où chaque chose dépend de chacune des autres, la pratique de l’essayiste semble être la seule à pouvoir porter ce discours complexe, à la fois politique, scientifique et littéraire. / How can the naturalist’s and the geographer’s scientific enquiries, a political thought ranging from liberalism to anarchism, and a writer’s style all revolve around the relationship between Man and Nature ? Such is a question raised —especially with regards to the Essay genre— by the works of Alexander von Humboldt (1769-1859), Henry David Thoreau (1817-1862) and Élisée Reclus (1830-1905). Within the bounds of a longer 19th century, which can be seen as an age of revolutions marked by the fading off of terræ incognitæ, the dwindling of the Wilderness, and a series of economical and political fits (Industrial and Political revolutions triggering the succession of strings of regimes), it appears critical to reconsider these names as those of genuine authors. From the heart of a politics of nature, they bind together the geographies of Man and the Earth, and their personal experience of Nature (as explored or inhabited) with a thought of community ceaselessly shifting from the Individual to the Human Kind, from the Microcosm to the Macrocosm. These Essay writers are the heirs of the Enlightenment in their struggle against slavery, despotism and colonialism (which they document); they object to leaving science in the hand of a positivistic, ethnocentric caste —they are the authors of popular sciences and the prophets of a literary democracy in the making. They are the pioneers of a modern exploration of the relationship between writing and knowledge, the crucial witnesses of a gradual differentiation of sciences that their universalistic literary paradigm sets out to avert. The ultimate point is to carry on approaching Nature as a whole (cosmos) in an era bringing about its division, as an object, into two separate categories of literary creation and scholarly knowledge. In the dawning light of literary ecology, and in this world description in which all things depend on all things, the work of the Essay-writer seems to be the only one able to voice this complex speech, made of politics, science and literature all together.

À partir de l’étude ethnographique de la maladie en milieu arakanais, cette thèse réfléchit sur le rapport individu-cosmos et sur le caractère pluriel, hybride et intégrateur de ce rapport. Une telle approche, innovatrice pour la Birmanie, s’éloigne de toute catégorisation et suggère en revanche que la médecine locale, la médecine d’origine occidentale, le bouddhisme Theravāda, l’astrologie, etc. forment un seul et même système de conceptualisation et de maîtrise de l’état de santé comme fruit du rapport au cosmos. La problématique développée s’appuie sur le postulat selon lequel la cohérence structurelle de l’ensemble – de son hybridité et de sa souplesse – réside dans le fait que les composantes sont liées entre elles par des rapports hiérarchiques et complémentaires. La hiérarchie, visible principalement dans l’hégémonie du référent bouddhique, est nuancée par le fait qu’aucune composante, y compris le bouddhisme, ne se suffit à elle même ; il y a toujours des restes qui échappent et qu’il revient à d’autres composantes de concevoir ou de gérer. Quant au caractère intégrateur du système, il est ici montré à travers l’exemple de la biomédecine dont l’intégration n’a été rendu possible qu’à travers de nécessaires adaptions du système lui-même. La thèse est organisée en cinq parties : la première est dédiée aux conceptions de la maladie ; la seconde partie est consacrée aux approches mises en œuvre par les villageois en vue de maintenir l’équilibre à tous les niveaux ; les troisième et quatrième parties portent sur la diversité des thérapeutes, de leurs formations et de leurs pratiques – aussi bien en termes de prévention que de soin – et de leur statut social ; la cinquième et dernière partie est quant à elle consacrée aux itinéraires multiples et complexes des malades. / Based on the author’s personal ethnographic research on sickness-related conceptions and practices in an Arakanese context, this thesis examines the relationship between the individual and the cosmos with particular emphasis on the plural, hybrid and integrating nature of such relationship.This approach, rejecting any form of categorisation, represents an innovation in the context of Burma and suggests that both Burmese and Western medicine, as well as Buddhism, astrology, spirit cult, etc. form a single system of conceptualisation and management of the state of health as a fruit of the relationship with the cosmos. The central point of this structure – its hybridity and plasticity – relies on the fact that the links between the various components are hierarchical and complementary. The hierarchy, notably the hegemony of Buddhism at various levels (conceptual, practical and of values) is counterbalanced by the fact that no component is enough to cope with all factors; there is always something missing, a remainder that other components can conceive and manage. The integrative nature of the system is showed through the example of western medicine, whose integration has produced some changes in the previous system.This thesis is structured in five parts : the first part is dedicated to sickness related conceptions, the second one to the practices the villagers rely upon in order to maintain the balance at all levels, while the third and the forth parts examine different kind of healers, their trainings, their (preventive and healing) practices and their social status; finally in the last one, health seeking behaviours of sick people are discussed.

This master`s thesis analyzes the pressure distribution on the premises of scintillation detector secondary electron in the variant with three aperture. The aim of this study is analyzing the fluid flow depending on the application of the third aperture in the entrance of the detector, thus creating more self-pumped chamber, which is responsible for ensuring a better distribution of pressure in the premises of the detector. The result of the analysis would be determining how to change parameters within the detector. If it is found that application of the third aperture has a positive effect on water flow in the premises of the detector, this arrangement may be used for improvement of the detector. Master`s thesis is divided into several chapters. First describes the basic principles of electron microscopy, including sample preparation, conditions for the proper functioning of microscopes and sharing different types of electron microscopes. The next chapters describe briefly the physical descriptions of gases flow in low pressures and small apertures, the mathematical models and simulation software used in this analysis. The analysis is done in SolidWorks with the module called Cosmos FloSimulation. The conclusion summarizes the results of the analysis, including graphical representations of simulation.

De nombreux critiques avaient détecté chez Jean Giono (1895-1970) la présence d’un vide affectant non seulement le sujet de son oeuvre mais aussi sa poétique. L’ennui, cette « brusque et radicale conscience du rien », le mensonge qui « reconstruit un monde au-dessus de l’abîme » (R. Ricatte) ou bien encore le « travail des sensations » vécu comme un « barrage contre le vide » (S. Vignes) sont des effets parmi d’autres d’un manque et d’une absence déterminante. Le vide explique aussi l’anonymat et les lacunes biographiques de ses personnages, les nombreux blancs et silences, les ellipses narratives et sémantiques, les césures et les discontinuités narratives... Il ne suffisait cependant pas de reconnaître l’existence d’un vide, d’un manque originaire dans cette oeuvre. Il fallait encore connaître sa nature. De quoi le monde gionien est-il vide ? La réponse se trouve paradoxalement dans ce que l’auteur s’est efforcé de ne jamais décrire ou plutôt dans ce qu’il a toujours décrit « en blanc » (J. Giono). En nous penchant sur ce qui, dans ses romans, était toujours décrit sans l’être, nous nous sommes aperçus que rien ne manquait davantage que Dieu. Dieu brille par son absence dans son oeuvre. Il est celui qu’il se refuse à décrire positivement car il est pour lui « le néant absolu », « l’absence de tout » (J. Giono). La théologie imprimée dans ses romans est une ‘‘théologie blanche’’. Sa vision du monde et de l’homme est toujours, et très délibérément, sans dieu/Dieu. Comme le dit le narrateur du Déserteur à propos des peintures pieuses et des ex-voto de son personnage : « il n’y a pas de dieu dans tout ça ». En analysant l’oeuvre gionienne à la lumière de cette absence, quatre ensembles de romans se sont dégagés selon un ordre qui dépasse les distinctions classiques établies, d’une part, entre une première et une seconde « manières », d’autre part, entre le « Cycle du Hussard » et les « Chroniques romanesques ». Ces quatre ensembles romanesques sont autant d’itinéraires de l’homme sans dieu/Dieu. Nous avons distingué celui de « l’humanisme païen », celui de l’héroïsme sublime, celui tragique voire tragi-comique des hommes condamnés à la chute, celui enfin des « âmes fortes » qui veulent se faire dieux en l’absence de dieu/Dieu. L’immense « chasse au bonheur » dont l’oeuvre romanesque de Giono est l’expression a rapport avec le ciel, un ciel sans dieu/Dieu. / Many critics spotted in Giono’s novels (1895-1970) the presence of a kind of emptiness which affected both his main topic and his poetry. Boredom « this sudden and drastic consciousness of nothingness », lie « which rebuilts a world on top of despair » (R. Ricatte) or « the work of sensations » (S. Vignes) felt as « a barrier against nothingness » reflect a void and a defining absence among other effects. This emptiness gives an explanation to his characters’ anonymity and gaps in biography, to the many gaps and silences, narrative and semantic ellipses, narrative caesura and discontinuities. Acknowledging the existence of a void, of an original emptiness, was not enough, its specific nature must be defined. What is missing in Giono’s world ? What is his world made of ? Paradoxically speaking the answer lies in what the author struggled not to describe or more precisely in what he described « en blanc » (J. Giono). Analysing what is described in his novels without really being described, I have realized that the One who is missing is God. God is conspicuous by his absence in his works. He is the one he refuses to describe positively as he is « the absolute absence ». The theology expressed is a ‘‘white theology’’. His view of the world and his vision of mankind, are always and in their tiniest details a vision without God. As the narrator of Le Déserteur puts it when he alludes to his main character’s votive offerings : « God is absent from all this. » Studying Giono’s works in the light of this absence, four collections of novels emerged according to an uncommon classification : on the one hand between a first and a second « manner » and on the other hand between « le Cycle du Hussard » and « les Chroniques romanesques ». These four collections of novels are routes taken by mankind without God. I have set apart : « a pagan humanist » route, a « sublime heroic » route, the tragic if ever tragicomic route of mankind doomed to their downfall, the last one the route of « strong souls » who strive to turn gods without God. The huge « quest for happiness » which is at the heart of Giono’s novels is related to heaven but a heaven without God.

[pt] Esta pesquisa estuda a relação entre as transgressões de Israel e os seus efeitos na natureza, de acordo com o livro de Amós. Distúrbios naturais, como terremoto, seca, eclipse solar e inundação, ocorrem ao longo do livro em contextos de ameaça de punição divina, devido às transgressões do povo. A relação entre os pecados de Israel e os transtornos cósmicos está bem estabelecida em Am 8,4-14, texto a partir do qual este trabalho procura compreender, precisamente, quais são os pecados da nação e que relação estes têm com os distúrbios cósmicos. Após isto, esta pesquisa estuda outros textos do livro que também tratam de convulsões no cosmos e que guardam relação temática ou vocabular com Am 8,4-14: Am 1,1.2; 2,13; 4,6-8.13; 5,8 e 9,1.5-6. O trabalho utilizou o método histórico crítico no estudo destes textos. A boa terra que YHWH concedeu para que todos partilhassem dos seus frutos, tornou-se cenário de injustiça: através das balanças enganosas, comerciantes tornavam-se mais ricos às custas do empobrecimento e escravização dos pequenos camponeses. A ordem social e a ordem cósmica estão conectadas, e por isso o mal praticado em Israel, ecoa na terra, no céu e no mar: tremores no solo, seca, escuridão e inundação vêm sobre aqueles que rejeitam a palavra divina. YHWH, criador e rei do universo, comanda o cosmos e este se volta contra a nação transgressora. Estas convulsões no cosmos são metáforas que o livro utiliza para retratar o caos que a nação se tornará, se YHWH remover a sua palavra da comunidade de Israel. / [en] This research studies the relationship between Israel s transgressions and their effects on nature, according to the book of Amos. Natural disturbances, such as earthquake, drought, solar eclipse and flood, occur throughout the book in contexts of threat of divine punishment, due to the transgressions of the people. The relationship between Israel s sins and cosmic upheavals is well established in Am 8,4-14, a text from which this work seeks to understand precisely what the nation s sins are and what relationship they have with cosmic disturbances. After that, this research studies other texts in the book that also deal with convulsions in the cosmos and that have a thematic or vocabulary relationship with Am 8,4-14: Am 1,1.2; 2.13; 4.6-8.13; 5.8 and 9.1.5-6. The work used the critical historical method in the study of these texts. The good land that YHWH granted for everyone to share in its fruits became a scene of injustice: through deceitful scales, merchants became richer at the expense of the impoverishment and enslavement of small peasants. The social order and the cosmic order are connected, and so the evil practiced in Israel, echoes in the land, in the sky and in the sea: tremors in the ground, drought, darkness and flood come upon those who reject the divine word. YHWH, creator and king of the universe, commands the cosmos and it turns against the transgressing nation. These upheavals in the cosmos are metaphors the book uses to portray the chaos that the nation will become if YHWH removes his word from the nation of Israel.

O esforço analítico e a distribuição dos capítulos estão baseados no esquema macro/microcósmico de “Cosmos-casa-corpo”. O primeiro capítulo situa a construção do Espiritismo Kardecista por seu codificador, o intelectual francês Hippolyte Rivail, conhecido por seu codinome, Allan Kardec (Paris, 1804-1869) e suas pretensões de unificar “ciência, filosofia e religião”, produzindo um Cosmos. O segundo capítulo apresenta o centro espírita, espaço sagrado de seu universo ritual. O terceiro capítulo está centrado no referencial semântico “corpo”, que surge como instrumento heurístico e recorte de análise. Analisando as concepções e imaginário sobre o corpo no Espiritismo Kardecista, o trabalho propõe que as relações entre o mundo espiritual, o centro espírita e corpo são determinantes para a compreensão da pessoa espírita. / The object of this study is to understand and highlight the role of the body in religious field by investing in an analysis of brazilian kardecist spiritual embodiment, which is constructed by social representations and imaginary. The analytical effort and the distribution of the chapters are based on the schema macro/microscopic – “Cosmos-house-body”. The first part deals with the construction of kardecism by its encoder, the French intellectual Hippolyte Rivail, known as Alan Kardec (Paris, 1804-1869), and its pretensions to unify “science, philosophy and religion”, producing a Cosmos. The second part presents the Spiritist Centre as a sacred space of its ritual universe. The third and last part is focused on the “body”, as semantic referential, which appears too as heuristic tool for analysis. Analyzing the conceptions and imaginary over the body in Kardecism, this work proposes that relations between the spiritual world, the Spiritist Centre and the body are crucial for understanding the spiritist person.

This thesis is about curses. It shows how the mechanics of cursing are intrinsically linked to shamanic practice in the ethnographic context of social, economic and political shifts in post-Soviet Kyzyl, the capital of the Autonomous Republic of Tuva. Moving beyond discourses that understand 'economics' as narrowly pertaining to wealth, power and the circulation of goods, the thesis explores curses as distinct social mechanisms within an 'occult economy' that constitutes a wider sociocosmic politics emergent from human and non-human interactions. Along these lines, while presenting Tuvan shamanism as central to cursing phenomena, the thesis explores the distinctiveness and efficacy of shamanic practice as a form of artistry embedded in instrument-derived (shamanic drum) and human (the shaman's voice) sound production. Thus, it challenges the 'classical' readings of shamanism which emphasise trance and mediumship usually seen as involving significant changes in the 'physical' and 'psychic' states of the shamans. Contextualizing cursing in the practice of Tuvan shamanism, the thesis illuminates the significance of sound creation among Tuvans in order to introduce the notion of 'turbulence' as integral not only to shamanic sound production, but also to immediate experiences of cursing and the overall patterning of the cosmos. More than that, bringing sounds and turbulence together in the context of shamanic rituals, it shows how sounds are imbued with a potency of their own rather than simply constituting a sonorous aspect of shamanic words. Along these lines, it contributes to a better understanding of im/materiality and the logic of representation. Lastly, exploring the multiplication of curses in the post-Soviet context, the thesis also offers an interpretative framework which unveils how occult phenomena can become efficacious analytical tools, allowing us to grasp the mosaic-like characteristics of the sociocultural contexts in which they are embedded. In this way, the thesis attempts to emancipate 'occultism' from the rigid dichotomies of tradition and modernity, and challenge those anthropological approaches to post-colonial transformations which emphasise cultural revivalism and ethnic identity, remaining caught in the usual dynamics of 'the old' and 'the new' - dynamics we need to leave behind.

Dark matter and dark energy clearly emerged from recent cosmological surveys as key ingredients of the Universe. Understanding their physical nature might be a way to unlock some of the mysteries in particle physics and General Relativity. In this talk I will discuss how gravitational lensing will have a unique contribution in this endeavor. I will also discuss how future weak lensing surveys, primarily designed to study dark matter and dark energy, will enable the detailed analysis of the physical processes underlying structure formation such as galaxies and clusters of galaxies. Presented on April 10, 2008.
