Galileo Galilei supported Nicolaus Copernicus astronomic theory, from which the former has attracted philosophical as well theological consequences. The celestial discoveries made possible with the usage of spyglasses allowed Galileo to challenge some of the aristotelic principles of cosmology and to break up the limits imposed to astronomy as hypothetical discipline which would aim just to "save the phenomena".
Galileu Galilei defendeu a teoria astronômica de Nicolau Copérnico, e dela extraiu consequências filosóficas e teológicas. As descobertas celestes com a utilização da luneta permitiram a Galileu questionar alguns princípios da cosmologia aristotélica, e romper os limites impostos à Astronomia, enquanto disciplina hipotética que teria como objetivo tão somente "salvar os fenômenos".

Full textAbstract:
Dissertação (mestrado)—Universidade de Brasília,Instituto de Ciências Humanas, Programa de Pós-Graduação em Filosofia, 2018.O presente trabalho visa analisar o desenvolvimento da noção de inércia em Galileu, tratando-se, portanto, de uma investigação que remonta às origens históricas para, então, realizar análises filosóficas. Dessa maneira, busca-se compreender as concepções aristotélicas acerca do movimento, imprescindíveis para que se possa refletir sobre a relação entre movimento e causalidade. Na sequência, procura-se apresentar os principais pensadores posteriores a Aristóteles cujas ideias contribuíram para o desenvolvimento científico que possibilitou a revolução copernicana e, consequentemente, a concepção galileana de inércia. Os escritos principais de Galileu são analisados, nomeadamente o Diálogo sobre os dois máximos sistemas do mundo e os Discorsi, obras nas quais o pesquisador italiano desenvolve de forma mais acurada a sua visão concernente ao movimento inercial. Por fim, apresenta-se uma discussão contemporânea relativa ao tema, a saber, se Galileu teria defendido uma inércia linear ou circular.
The present work aims to analyze the development of the notion of inertia in Galileo, dealing, therefore, with a investigation that goes back to historical origins to then carry out philosophical analysis. In this way, it seeks out to understand the Aristotelian conceptions concerning movement, which are indispensable so that we can reflect about the relationship between movement and causality. In the sequence, one looks for to present the main thinkers later to Aristotle whose ideas contributed for the scientific development that made possible the Copernican revolution and, consequently, the Galilean conception of inertia. We analyze the main writings of Galileo, namely the Dialogue Concerning the Two Chief World Systems and the Discorsi, works in which the Italian researcher develops more accurately his vision concerning the inertial movement. Lastly, it presents a contemporary discussion on the subject, namely whether Galileo would have defended a linear or a conception of circular inertia.

Previous issue date: 2006-10-10This dissertation has as subject the relation of Copernicus system with the Bible; a crucial question that may be analyzed in Galileo s Letter to Cristine of Lorene, wrote in 1615, in which this subject is treated by the celebrated Florentine. At first, some observations of Galileo are considered (solar spots, phases of Venus and Jupiter satellites) which gave credit to the thesis of Nicolaus Copernicus, who placed Sun in the center of Universe and made Earth to turn around itself and around the Sun. This thesis was introduced more than one half century before, but without proofs to support it. The observacional discoveries of Galileo provided support for the copernican system, being argued the character of this support: a rigorous proof (necessary demonstration) or endorcement of an hypothesis saving the phenomena . We endeavor to analyze the Letter of Galileo to Cristine of Lorene, stressing the strategies used by Galileo to show the agreement of the copernican system with the Bible; stressing also as Galileo conceives the study of the book of Nature and the interpretation of the Bible. For Galileo, Nature as much as Sacred Scripture are works of God; they are, therefore, two books without error and cannot contradict one another; however, Nature and Scripture are two books written in different languages, with different purposes, not being able to be read in the same way
Esta dissertação tem como objeto a relação do sistema de Copérnico com a Bíblia; questão crucial que pode ser analisada na Carta a Cristina de Lorena, de Galileu, escrita em 1615, na qual tal tema é abordado pelo célebre florentino. São consideradas de início algumas observações de Galileu ( manchas solares, fases de Vênus e satélites de Júpiter) que davam crédito à tese de Nicolau Copérnico, que colocava o Sol no centro do universo e fazia a Terra girar em torno de si mesma e ao redor do Sol. Tese introduzida mais de meio século antes, mas sem provas para fundamentá-la. As descobertas observacionais de Galileu proporcionaram sustentação para o sistema copernicano, discutindo-se o caráter desta: prova rigorosa (demonstração necessária) ou fundamentação de uma hipótese capaz de salvar os fenômenos ?. Procuramos analisar a Carta de Galileu a Cristina de Lorena, destacando as estratégias utilizadas por Galileu para mostrar o acordo do sistema copernicano com a Bíblia; destacando também como Galileu concebe o estudo do livro da Natureza e a interpretação da Bíblia. Para Galileu, tanto a Natureza como a Sagrada Escritura são obras de Deus; são, portanto, dois livros desprovidos de erro e não podem se contradizer; no entanto, a Natureza e a Escritura são dois livros escritos em linguagens diferentes, com finalidades diferentes, não se podendo lê-los da mesma forma. As fontes primárias utilizadas foram as cartas de Galileu que se referem à relação do sistema copernicano com a Bíblia, principalmente a carta a Cristina de Lorena. Também utilizamos textos da época que foram úteis para a compreensão do confronto entre ciência e religião no caso em questão

Full textAbstract:
L'oeuvre de Galilée (1564-1642) est abordée dans une perspective littéraire autour de deux axes principaux : le genre dialogique et les enjeux de l'écriture. L'accent est mis sur l'argumentation et les atouts du style habilement exploités pour la rendre plus séduisante. Dans la première partie, l'histoire du dialogue avant Galilée vise à éclairer les motivations d'un tel choix littéraire chez le savant décidé à livrer au public son audacieuse défense du copernicianisme. On assiste d'ailleurs à une extension du potentiel expressif de ce genre, grâce au subterfuge de la théatralisation, où s'expriment brillamment les talents de l'écrivain. La deuxième partie s'attache essentiellement aux procédés stylistiques à l'oeuvre dans la "Première journée". À partir de quelques enquêtes linguistiques, l'étude porte successivement sur dénotation et connotation, concepts modernes derrière lesquels se profile la distinction aristotélicienne entre logos, ethos et pathos. La réflexion s'oriente enfin vers les formes de littérarité que l'écrivain Galilée met au service de l'ambitieux message du savant. C'est ce lien puissant entre écriture et "forma mentis" nouvelle qui nous suggère de mettre l'accent sur l'admirable rhétorique du dialogue. Brio du style et du raisonnement, mouvement de la plume et de la pensée pour une oeuvre suspendue entre l'univers de la science et celui de l'art, qui se détache majestueusement de l'esthétisme pré-baroqueGalileo 's work is tackled in a literary perspective aroun two main lines of study : the dialogical genre and the stakes of style. The emphasis is put upon the argumentation and assets of qualities of style, skillfully exploited in order to make it more attractive. In the first part, the history of the dialogue before galileo aims at throwing light on the motivations of such a literary choice for the scholar determined to put forward to the public his bold defence of copernicanism. Besides, we can witness and extension of the expressive potential of the genre, thanks to the subterfuge of theatralisation in which the raconter 's talents can express themselves brilliantly. The second part is mainly devoted to the figures of speech used in the first day. From a few linguistic researches, the study deals successively with denotation and connotation, modern concepts behind which emerges the aristotelian difference between logos, ethos and pathos. The reflection eventually directs itself toward the literary forms which galileo, as a writer, puts at the service of the scientist's ambitious message. It is this powerful link between style and "forma mentis" which suggest to us to put the emphasis on the dialogue's admirable rhetoric. Brilliancy of the style and of reflection strokes of pen and thought for a work hanging between the world of science and art, which is majestically brought out of pre-baroque aestheticism

Essa pesquisa tem o objetivo de discutir qual é o papel do diálogo na construção do conhecimento e no Ensino de Física. Foi realizada uma revisão bibliográfica a respeito dos conceitos de diálogo e conhecimento presentes na literatura e desenvolvido um estudo de caso histórico-epistemológico sobre esses conceitos a partir das epistemologias de Paulo Freire e Galileu Galilei. A síntese entre os pensamentos desses dois autores mostra que os principais papéis do diálogo na construção do conhecimento e no Ensino de Física são: fundamentar os processos de educação e construção de conhecimento de forma dialética e totalizante; estabelecer o encontro dos seres humanos entre si e com o mundo, visando sua humanização, transformação e emancipação por meio do conhecimento; propiciar a problematização e a descodificação da realidade de modo a transformá-la; fundamentar o processo de investigação científica e a sua comunicação; propiciar a escolha de temas significativos que, estabelecendo um contato com a realidade dos educando(a)s e partindo dela, tenha condições de problematizá-la, entendê-la e transformá-la; fundamentar atividades e ações pedagógicas no Ensino de Física que, pautando-se nos conhecimentos científicos construídos, levem o(a)s estudantes a um autoconhecimento, à percepção crítica de sua presença no mundo e, sobretudo, ao desenvolvimento de sua autonomia e responsabilidade perante a própria formação e a transformação do mundo; desnaturalizar, criticar e repensar, através do conhecimento científico, os preconceitos e as ideias enraizadas na sociedade pela ideologia dominante; e, por fim, estabelecer o contato entre a cultura trazida pelo(a)s aluno(a)s e a cultura científica.This research aims to discuss the role of dialogue in the construction of knowledge and in Physics Teaching. A literature review was carried out upon the concepts of dialogue and knowledge, as well as a historico-epistemological case study was developed regarding these concepts, based on Paulo Freire\'s and Galileo Galilei\'s epistemology. The synthesis between the thoughts of these two authors shows that the main roles of dialogue in the construction of knowledge and in Physics Teaching are: underpin the processes of education and construction of knowledge in a dialectical and totalizing form; establish the meeting of human beings with each other and with the world, aiming at their humanization, transformation and emancipation through knowledge; enable the problematization and decoding of reality in order to transform it; underpin the scientific research process and its communication; enable the choice of significant themes which, establishing a contact with the reality of the students and starting from it, has conditions to problematize, understand and transform it; underpin pedagogical activities and actions in Physics Teaching which, based on the scientific knowledge built, lead students to self-knowledge, a critical perception of their presence in the world and, above all, the development of their autonomy and responsibility towards their own education and the transformation of the world; denaturalize, criticize and rethink, through scientific knowledge, the prejudice and ideas rooted in society by the dominant ideology; and, finally, establish the contact between the students\' culture and the scientific culture.

Através deste trabalho de pesquisa, pretende-se apresentar uma análise sobre a representação do desenvolvimento tecnológico na dramaturgia de Bertolt Brecht na peça teatral “A Vida de Galileu Galilei”. Na primeira parte, apresenta-se o panorama histórico do século XX, tema que serve como base ao assunto tratado. Na segunda parte do trabalho, apresentam-se as referências que articulam a tecnologia como tema político, no âmbito do período analisado. Por último, a análise refletirá sobre a relação social da tecnologia com a sociedade no decorrer do século XX, investigando a hipótese de que a tecnologia faz parte da ideologia social hegemônica mas pode ser usada também pela militância cultural e democrática. A peça analisada retrata o início da Ciência moderna, e evidencia como desde o seu início a ciência nunca foi imparcial frente aos conflitos ideológicos e sociais. Portanto, analisar a peça e colocá-la no contexto da história contemporânea permite entender a relação da tecnologia com a linguagem e com a estética no escopo de cada período.In this research work we intend to present an analysis on the representation of technological development in the dramaturgy of Bertolt Brecht. In the first part of this work the 20th century will be presented as the historic base for this study. The second part will reflect on the social relation between technology and society throughout the 20th century, an era in which technological rationality cursed the paths of History. At last, the analysis will be made taking for model the play “Life of Galileo”. The play takes as a scenario the initial phase of the Modern Age, making it clear that Science has never been neutral to ideological and social conflicts. Therefore, making an analysis of this play and putting it in comparison with the events of Contemporary History allows us to understand the relation between technology, language and aesthetics in the scope of each historic period that is analyzed in this work.

El presente trabajo establece los siguientes puntos fundamentales:
1) que la elaboración ontológica galileana del concepto metafísico de una naturaleza independiente y de un pensamiento automático y objetivo de las cosas ha revolucionado de una manera histórica la cultura institucional y popular de los siglos XVI y XVII, orientando un nuevo horizonte de sentido;
2) que en su totalidad la revolución de Galileo tuvo su primer y crucial desarrollo en la propagación, académica y urbana, de una mera opinión, que, en un momento dado, se convirtió, en un primer momento en convicción política y luego en saber social;
3) que el galileismo, basado en el consenso que fue capaz de determinar en tomo suyo, llegó a organizar la lucha política de los innovadores contra las autoridades tradicionales en el campo de la ciencia;
4) que el alcance político-filosófico de la ciencia galileana del movimiento se remonta al valor performativo de sus palabras y a lo tecnológico de sus objetos; que, sobre todo después de la síntesis newtoniana, el galileísmo se ha convertido en el símbolo de la modernidad clásica no tanto sobre la base de sus descubrimientos, en parte erróneos, sino por causa de la definición físico-matemática de la naturaleza y por la elección decisiva del objeto técnico como organon del conocimiento.
La presente tesis se estructura en tres capítulos que a través de los textos mismos se cortocircuitan en torno al mito científico galileano de la independencia de la naturaleza con respecto a Dios, a la salida de Dios de la escena del mundo y a la concepción de la historia como un avance tecnológico del conocimiento, tres concepciones fundamentales de las que la filosofía experimental no puede prescindir. A través de esta operación, la primera parte del primer capítulo, propondrá una mirada sobre el joven Galileo; es decir, sobre la primera fase de su pensamiento. Observaremos aquí que Galileo, aun manteniendo a grandes rasgos su peripatetismo hasta el 1602/1604, empezó a sentir a partir de 1590/1595 una cierta impaciencia y disgusto ante la autoridad de Aristóteles; que lo llevaron lenta pero firmemente a despegarse de manera crítica de la ontología tradicional, integrando progresivamente la astronomía de Copérnico con una nueva concepción del movimiento y de la estructura de la materia derivada del estudio simultáneo sobre la estática e hidrostática de Arquímedes y el atomismo democríteo. En los primeros pasos de los Juvenilia, del De motu, de las Mecaniche y, sobre todo, en el periodo comprendido entre 1602/07, mostraremos que, independientemente de la construcción del telescopio, Galilei esbozó ya las piedras angulares de la
física sublunar en un sistema heliocéntrico. En la segunda parte del primer capítulo hemos llamado la atención sobre el período de incubación del Sidereus Nuncius, en el que Galileo pasó de la elaboración de un realismo platónico a la elaboración de un realismo telescópico, con el que fue finalmente posible para él ver con sus propios ojos lo que antes de 1610 era sólo una cuestión de opinión y simpatía.
En el segundo capítulo, analizamos, a partir de lo dicho anteriormente, el cambio en la filosofía experimental sucesivo al 1616, es decir, desde su fase crítica a la controversia, a través de las obras de la madurez.
En el tercer capítulo hemos dado una mayor contextualización a lo que hemos expuesto en los dos primeros capítulos y, a través de las obras publicadas por los peripatéticos contra la filosofía de Galileo, acentuamo los efectos políticos de la verdad con la que Galileo, en la disputa contra los aristotélicos, trazó los contornos finales de la Nueva ciencia y con ellos la “modernidad clásica”.In order to start a genealogy of the strong sciences demonstrates the following points: 1) the Galileian metaphysical concepts of the nature’s independence and of technological object, revolutionized historically the European culture of the XVI-XVII centuries and opened a new horizon of sense; 2) the development of the galileian nature’s philosophy from mere opinion to public conviction and from political conviction to scientific knowledge; 3) the galileism by common consent organized and identified political struggle of the innovators against the traditional authorities on science; 4) they political and philosophical importance of the galileian science is due to the performative and technological value of its words and objects; galileism, expecially after the Newtonian synthesis, became the symbol of the classical modernity not because of his discoveries but thanks to the physical-mathematical definition of the nature and to the revaluation of the technical object as instrument (organon) for knowledge. Thesis is structured of three chapters that, on the basis of the literary sources, show how Galileo invented the nature’s scientific mith of independence from history knowledge and the concept of knowledge’s history as progress. In the first chapter was possible discover the Galileo’s thought beyond the traditional approaches and studied the juvenile works, where we observe that the young Galileo, despite being an Aristotelian until 1602/1604, already from 1590/1595 started to express intolerance to Aristotele’s authority. This intolerance led him away critically from the traditional ontology in Juvenilia, in De motu and Mecaniche and, specially between 1602 and 1607, integrated Copernico’s astronomy with Archimedean hydrostatic and democritean materialism and defined the principles of his new physic in a heliocentric system. In the second half of the first chapter, Galileo moved from platonic realism to telescopic realism that allowed him to see with his own eyes what, before 1616, was only a opinion and sympathy. In the second chapter we analyzed the turning of exsperimental philosophy after 1615, from the critical phase to the polemic one. In the third chapter through the historical analysis of the peripatetic’s works, we pointed out the political of Galileo’s philosophy and how Galileo outlined the modernity.

Vincenzo Galilei (1520?-1590) was born at Santa Maria a Monte, a small city near Florence. He was a music-theorist, a lutenist and a teacher. He was sent to Venice to start theoretical studies with Gioseffo Zarlino and interested in the studies of ancient texts, he was helped by the philologist Girolamo Mei. Galilei had basically two main goals. The first was to clarify, what he called misunderstood facts of the history of music and the second was to restore music to its original place among the sciences. Therefore he explored the nature of ancient music in a very detailed and systematic fashion and provided novelties based mostly on the results of his investigative method. In experimenting with different materials, cotton, metal, wood, etc., combined into different shapes, Galilei showed to take matter into account to know how it affects the behavior of the instruments. Despite the fact that Music was based on the concept of number, and that most of the musical theorists of the sixteenth century were not interested in the physical nature of sound or in the materials that produce it, Vincenzo Galilei succeeded to provide to Music a new basis, named sound
Vincenzo Galilei foi um músico teórico, alaudista e professor, nascido em uma pequena cidade nos arredores de Florença na primeira metade do século XVI. Embora pouco se saiba de sua formação, sabe-se que após os seus estudos com o teórico Gioseffo Zarlino, manteve intensa correspondência com o filólogo Girolamo Mei que o introduziu aos textos da antigüidade clássica. Vincenzo Galilei estudou e criticou os textos clássicos e desenvolveu experimentações com instrumentos. Ao estudar os instrumentos musicais e os materiais de que eram constituídos, Galilei buscava solucionar problemas musicais. A sua análise dos diversos comportamentos dos materiais, assim como dos instrumentos, proveu um novo fundamento para a música teórica. Galilei concluía que a Música não estava embasada no número, como acreditavam alguns teóricos de sua época, mas no fenômeno físico sonoro

Full textAbstract:
Se toma en cuenta que en la investigación de la naturaleza se supone el postulado denominado “realismo ontológico” que define el enfoque de la investigación fundamentalmente como realista. Se muestra que en las investigaciones de la naturaleza realizadas por Galileo subyace de hecho el postulado del realismo ontológico; por ello y por el hecho de que tal postulado, por sus raíces presocráticas, presenta un carácter materialista, el enfoque de la actividad científica galileana fue de hecho realista materialista. El postulado del realismo ontológico materialista, o mecanicista en sentido lato, señala que hay un mundo exterior que existe independientemente del sujeto cognoscente y que es material. Este postulado supone a su vez un concepto general de objetividad ontológica mecanicista según el cual la objetividad es una condición de la materia en sí misma y no lo pone el sujeto cognoscente. Pero, para hacer frente al racionalismo esencialista que identifica propiedades primarias con entes, se distingue dos sentidos o dimensiones diferentes de objetividad ontológica: dimensión propia y dimensión derivada. Esta distinción es paralela a dos niveles de realidad con estatus ontológico distinto: elemental (primario) y compuesto (secundario). En dimensión propia la objetividad se aplica en el dominio de los elementos a los que se reduce la materia corpórea en última instancia y algunos de cuyos rasgos básicos, en la versión final galileana, son: indivisibles y no extensos, tal vez sin consistencia alguna, análogos a puntos geométricos, plenos, no vacíos. De elementos con tales condiciones se dice, entonces, que son objetivos en sentido ontológico propio. La dimensión derivada del concepto de objetividad ontológica se aplica en el dominio de las propiedades de objetos materiales, entre las que Galileo considera la forma, cantidad de materia y movimiento mecánico fundamentalmente; de tales propiedades se dice que son objetivas en sentido ontológico derivado. En ninguna de las dos dimensiones se ha encontrado que Galileo haya salido del esquema mecanicista. Cuando tuvo la necesidad de fundamentar la matematización de la naturaleza (posibilidad de la física matemática) estimó que no era necesario salir del marco ontológico mecanicista, sino que consideró suficiente una concepción realista de las teorías de tipo semántico. En tal intención, postuló la existencia de “propiedades matemáticas” en los cuerpos (propiedades mecánicas o primarias) y consideró un puente semántico entre estas propiedades materiales (no conceptuales) con estatuto ontológico derivado y los conceptos e ideas de la ciencia matemática, estos últimos son así objetos conceptuales con significado fáctico. De modo que no fue necesario postular en la naturaleza material la existencia de entidades ideales (objetos matemáticos) con estatus ontológico primario. Se complementa este estudio con una breve consideración semántica intuitiva orientada a enfatizar el carácter complejo y sistémico del concepto de objetividad ontológica.Tesis

Orientador: Cláudia Valéria Seullner BrandãoResumo: Os gatos possuem papel de destaque como animais de estimação, assim como em estudos oftalmológicos comparativos. Pelo conhecimento dos autores, até o momento, a avaliação de bulbo de gatos utilizando tomógrafos e topógrafo associados, por meio dos sistemas de câmeras Scheimpflug duplas e um disco Plácido, não foi descrita na literatura. O objetivo deste estudo foi analisar a córnea em gatos considerando as curvaturas anterior e posterior, o poder total e espessura da córnea pelo sistema de duplo Scheimpflug e disco de plácido. Na ceratometria anterior (SimK) verificou-se valores de 38,37 ± 0,83D, ceratometria posterior -4,89±0,34D e poder corneal total médio 38,04 ± 0,94D. Quanto à espessura corneal central foi obtido valor médio de 617,34 ± 53,38 μm, superior aos encontrados em outros trabalhos utilizando a paquimetria ultrassônica. A utilização do sistema duplo Scheimpflug e disco de plácido foi efetiva em gatos domésticos e permitiu a obtenção de valores ainda não descritos na literatura para a espécie, tais como ceratometria anterior nas zonas da córnea, ceratometria corneal posterior, poder corneal total, volume corneal.
Abstract: Cats have an important role as pets and in ophthalmologic comparative studies. To the autors’ knowledge, this is the first study that evaluates cornea of cats using a device that combine tomography and topography, through dual Scheimpflug cameras and a Placid disc. The aim of this study was to evaluate anterior and posterior keratometry, total corneal power and pachymetry using dual Scheimpflug and Placid disc system. Concerning anterior keratometry (SimK), the value obtained was 38,37 ± 0,83D, posterior keratometry -4,89±0,34D and total corneal power 38,04 ± 0,94D. Regarding the pachymetry, the mean CCT value obtained was 617,34 ± 53,38 μm, superior to those find in other studies using ultrasonic pachymetry. The use of dual Scheimpflug and Placid disc system was effective in domestic cats and enabled the description of values that have not been described in the literature in felines yet, such as anterior keratomemetry in the corneal zones, posterior keratommetry, total corneal power, corneal volume.

As ciências naturais são vistas como ciências empíricas porque a experimentação tem um papel central no processo de produção de novos conhecimentos (Höttecke, 2000). No entanto, a dimensão empírica da prática científica, enquanto constitutiva do conhecimento científico, é pouco explorada nas aulas de Física. A exemplo do que acontece com os aspectos históricos e filosóficos, geralmente concebidos como adereços motivacionais ao ensino da ciência, a experimentação científica, que a prática laboratorial representa, permanece ocultada, quando não distorcida. O objetivo deste trabalho é discutir o uso de "experimentos históricos" no Ensino de Física como estratégia no processo de contextualização e articulação da dimensão histórica do conhecimento científico na sala de aula. Como exemplo desta articulação, sugerimos o resgate da experiência do Plano Inclinado, extraída da obra Discursos e Demonstrações Matemáticas acerca de Duas Novas Ciências (1638), de Galileu Galilei (1564-1642), onde a lei de queda dos corpos é investigada. Propomos ainda a exploração desse tema no contexto de sala de aula, sobretudo, através do emprego de simulações computacionais com o software Modellus. _______________________________________________________________________________________ ABSTRACT
The natural sciences are regarded as empirical sciences because experimentation plays a central role in the process of production of new knowledge (Höttecke, 2000). However, the empirical dimension of scientific practice even though being an essential part of scientific knowledge is poorly used in the teaching of physics inside the classroom. As what happens with the historical and philosophical aspects, in general considered as secondary aspect to science education, scientific experimentation, represented in the laboratory practice, remains occult if not distorted. The purpose of this work is to discuss the use of “historical experiments” in the Teaching of Physics as a strategy in contextualizing and articulating the historical dimension of scientific knowledge inside the classroom. As an example of this articulation, the use of the inclined plane used in the Discourses and Mathematical Demonstrations about the Two New Sciences (1638) of Galileu Galilei (1564-1642) is suggested, where the law of the fall of the bodies is investigated. We propose in exploration, that this should be researched in the classroom context, mainly through the means of computational simulations with the software Modellus.

Full textAbstract:
When Bertolt Brecht flees Nazi Germany in 1933 he spends fourteen years in exile where he writes some of his most significant works, among them, Leben des Galilei. In his Leben des Galilei, Brecht explores the relationship between the individual and society. Using the historical Galileo Galilei as context, Brecht elucidates the responsibility that scientists must accept for how their discoveries are put to use. With his Galilei figur, Brecht expresses his belief that scientific advancement should be employed for the societal advancement of the common person. Brecht wrote three versions of his Galilei work, each showing significant parallels to Brecht's experiences during the corresponding time period of his exile. This thesis will illustrate these parallels. It will first show that the Galilei thematic is to be found in the very first years of Brecht's exile. It then deals with the influences surrounding the writing of the first version while Brecht is in Denmark. The second part of the thesis focuses on Brecht's exile in America and the resulting second version of his Galilei work. Here, working with Charles Laughton on an English translation of the work, Brecht's Galilei undergoes a fundamental change. Brecht attempts to alter the positive perception of the first version's Galileo who cleverly outwits the Inquisition and secretly has his work the Discorsi smuggled out of Italy. Brecht now wants to portray Galileo as a traitor of the people, who missed his chance to help the common people overcome the suppression they were subjected to. This change is strongly influenced by Brecht's experiences in America and the dawning of the Atomic Age. The last section of the thesis deals with Brecht's return to Europe and the third version of Leben des Galilei written in East Berlin. This is a result of translating the American version into German and the addition of scenes and individual elements cut from the first version to make it more appropriate for American audiences. Brecht maintains and tries to heighten the negative portrayal of Galileo as traitor of the common people.

Previous issue date: 2014-06-14This work aims to make a suited reconstruction from the classic experiment of the inclined plane, attributed to Galileo Galilei. The intention is to apply it to high school classes, claiming that it might motivate these students to learn concepts related to physics, and should be able to better understand the subjective nature of what is behind the science and its construction process. It is intended to perform the experiment and guide the activities in order that the activities that students can better understand scientific knowledge as a result of human construction, as well as its inherent limitations, realizing that the science development is based on model making and experimentation, among others, which can be modified along the time. The discussion and investigation of the assumptions made by the great physicist, in the elaboration of the theory of falling bodies, and their validity, may result in rich discussions of scientific development. Students may discuss the possibility of adoption and acceptance of misconceptions in science, and what implications these have for the development of scientific theories. The work analyzes the measurement of time of ball bearings on the inclined plane, evaluating the primitive methods that Galileo could have used to reach its conclusions regarding this type of movement. The dissertation also approaches modern methods, as for example, the measurements of falling objects using a tape recorder of a microcomputer, and finally both time measurement procedures are discussing emphasizing historical and modern discussion of both forms, comparing historical and modern aspects in the development of science. Performed activities, finalize the work with the results of the project and its completion, prospects of continuity, assessing the feasibility of its use as an educational product that can serve as a tool in the process of teaching and learning in high school and used by other teachers in other contexts.
Este trabalho objetiva fazer uma reprodução adaptada do experimento clássico do plano inclinado, atribuído a Galileu Galilei. A intenção é a criação de situações de aprendizagem para serem aplicadas em turmas do ensino médio, pretendendo que as mesmas possam vir a ser um elemento motivador para que estes alunos aprendam conceitos ligados à física, bem como tenham condições de melhor perceber o caráter subjetivo que existe por trás da ciência e do seu processo de construção. Pretende-se com a realização do experimento, e com o direcionamento dado às atividades, que os estudantes possam melhor visualizar o conhecimento científico como fruto de uma construção humana, bem como suas limitações intrínsecas, percebendo que este se solidifica baseado na construção de modelos e hipóteses, que são modificados com o decorrer do tempo. A discussão e averiguação das hipóteses feitas pelo grande físico, na elaboração da teoria da queda dos corpos, bem como a validade das mesmas, poderá ser fruto de ricas discussões sobre o desenvolvimento científico. Os alunos poderão discutir sobre a possibilidade da adoção e aceitação de ideias equivocadas na ciência e as implicações que as mesmas teriam para a elaboração das teorias científicas. O trabalho pretende analisar a medição dos tempos de rolamentos de esferas sobre o plano inclinado, avaliando os métodos que Galileu poderia ter utilizado para efetuá-los e suas conclusões a respeito deste tipo de movimento, bem como fazer uma releitura apresentando métodos mais modernos, como por exemplo, a medição destes tempos com o gravador de som de um microcomputador, e a posterior discussão sobre ambas as formas, confrontando aspectos históricos e modernos na elaboração da ciência. Aplicadas as atividades, finalizaremos o trabalho com os resultados do projeto, e sua conclusão, perspectivas de continuidade, avaliando a viabilidade de sua utilização como um produto educacional que possa servir como ferramenta no processo de ensino aprendizagem em nível médio e utilizado por outros professores em outros contextos.

Full textAbstract:
The history of Bertolt Brecht’s play Leben des Galilei extends through the writing of its three versions during 1938 to 1955—a period of two decades that also encompassed the entirety of the Second World War. The period also covers the atom bomb from its development to America’s use of the bomb in Hiroshima and Nagasaki, as well as the beginning of the Cold War, which included the sustained threat that nuclear weapons might be used any day. This thesis traces, and offers interpretations of, changes in Brecht’s Leben des Galilei from its inception in 1938–1939—when the protagonist, a scientist, is portrayed in a positive light—through the play’s American version in 1947, where it bitterly accuses science and scientists of having betrayed society and humanity, and finally to its last version in 1955, where the protagonist struggles to prevent the normalization—the familiarization—of the threat of nuclear warfare.
Next to the writing of the Leben des Galilei, the thesis also focuses on the main critical readings of the play. A large fraction of the critical readings, but not all of them, interpret the play either as a judgment of science or as an invitation to pass judgment on science.
The thesis compares Leben des Galilei with three different groups of other texts. The first comparison is with two other plays that also address the problem of science in the age of nuclear weapons, and the second comparison is with other work of Brecht himself. The first comparison leads to the observation that the muted note of optimism in the final version of Leben des Galilei is exceptional, and the second comparison to the apparently unrelated observation that it was uncharacteristic of Brecht to make explicit a certain literary allusion in Leben des Galilei. The two observations converge to a possible common explanation from a comparison with a still third group of texts, a cycle of Native American myths which appear in the oral traditions of various Native American tribes spread throughout the New World.
Finally, the thesis addresses the question of why a modern-day literary text, addressing the essentially modern problem of nuclear warfare, and addressing that problem using the essentially modern techniques of Brechtian theatre, might have structures parallel to the structures of primitive mythology.

De nombreuses représentations de Galilée évoquent un conflit entre lui et l’Église catholique : Galilée devient le symbole de l’opposition entre la science et la religion. Or, dans la Lettre à Christine de Lorraine, Galilée propose une réflexion à propos de l’interprétation des Écritures dans un contexte de philosophie naturelle. Après avoir présenté une synthèse de cette Lettre ainsi que le contexte de rédaction, il sera possible de l’interpréter à partir d’une typologie de l’articulation des discours religieux et des discours scientifiques et ce, dans le but de caractériser les rapports "science et religion" développés par Galilée. La typologie sera ici un outil herméneutique permettant de déceler ces rapports à partir de catégories prédéfinies (conflit, indépendance, complémentarité, intégration). Il apparaîtra que Galilée présente plusieurs types de rapports « science et religion ». Cette approche a l’avantage de développer une interprétation originale de la Lettre.

Full textAbstract:
Con l’avanzare della pandemia di Covid-19 si è attribuita importanza via via crescente ad alternative valide alle classiche modalità didattiche. In questo contesto le università hanno trovato rapidamente una soluzione svolgendo le lezioni, che precedentemente venivano svolte in presenza, su piattaforme online. Ma come possiamo gestire le attività che precedentemente si svolgevano in laboratorio?
In questo elaborato mi occuperò di didattica laboratoriale partendo da Galileo Galilei, analizzando il suo modo di procedere in ambito sperimentale e cercando di capire in cosa consistesse il suo “metodo scientifico”. Mi soffermerò poi su Augusto Righi, sottolineando la sua importanza nella scienza e nella didattica dell’Istituto di Fisica bolognese. Le potenzialità che egli attribuisce all’illustrazione e spiegazione degli apparati sperimentali ai suoi studenti è già evidente dall’analisi della prima lezione svoltasi nell’Istituto stesso nel giorno della sua inaugurazione.
Vedremo quali sono stati gli sviluppi storici principali della didattica laboratoriale dagli anni `60 ad oggi che hanno portato ad un’impostazione dei laboratori così come noi li svolgiamo attualmente e, cercando di rispondere alla domanda precedente, proporrò una valida alternativa alla classica metodologia con cui il docente svolge la prova in classe, attraverso la registrazione di video.
I video permettono di introdurre degli elementi che normalmente i docenti non posso utilizzare, come ad esempio rappresentazioni grafiche di vettori, campi, particelle o altri elementi fisici concettualmente rilevanti.
Nell'ultima parte della tesi illustrerò il progetto di un'attività laboratoriale strutturata con le nuove metodologie apprese. Grazie a questa ampia analisi dell’evoluzione della didattica sperimentale ho potuto introdurre molti aspetti rilevanti all’interno delle attività proposte, tuttavia, nel tentativo di progettarla in prima persona, mi sono scontrato con una serie di problematiche non banali.

Full textAbstract:
Cette etude se propose de rendre compte de la contribution de galilee dans la constitution du concept de temps de la mecanique classique. Elle comprend six chapitres, repartis en trois parties. La premiere partie est consacree a une esquisse de l'histoire de la notion du temps avant galilee. Elle commence par un expose synthetique de la physique d'aristote, suivi d'un survol de sa theorie du temps. Celle-ci est suivie, ensuite, dans son evolution historique dans la pensee scientifique et philosophique de l'antiquite, du moyen-age et de la renaissance. La deuxieme partie est consacree aux travaux de jeunesse de galilee, ou la notion du temps fait son apparition dans la critique galileenne de la philosophie naturelle traditionnelle et dans l'analyse des machines simples. La troisieme partie suit la genese de la notion du temps dans la pensee dynamique de galilee, a travers l'etude de ses notes manuscrites et de ses ouvrages de maturite. C'est dans cette periode que la notion galileenne de temps recut un traitement mathematique et une mesure physique. Le temps est ainsi progressivement erige en variable independante des variations de la vitesse dans le mouvement naturellement accelere et fait son entree dans les equations et les lois de la chute des corps. Parallelement, il est dote d'une theorie physique et mathematique qui lui a fourni la base d'une mesure physique precise par le moyen des lois du pendule. Les lois de fonctionnement de cet instrument permirent son application dans des buts pratiques, notamment pour la mesure des longitudes et pour la construction d'une horlogeThis study proposes to show the contribution of galileo galilei in the formation of the classical mechanics' concept of time. It comprehends six chapters, distributed into three parts. The first part is devoted to an outline of the history of the notion of time before galileo. It begins by a synthetic account of aristotle's physics, followed by a summary of his theory of time. This last is followed, next, in its historical evolution in the scientific and philosophical thought of the antiquity, the middle-ages and the renaissance. The second part is devoted to the youth works of galileo, where the notion of time makes its apparition in his thought, in the galilean critics of the traditional natural philosophy and in the analysis of the simple machines. Finally, the third part follows the genesis of the time's concept in galileo's dynamical thought, through the study of his manuscript notes and his maturity's works. In this period, the galilean notion of time received a mathematical treatment and a physical measure. It was progressively eriged as an independent variable of the speed's variations in the naturally accelerated motion and made its entry in the equations and laws of the falling bodies. In a parallel direction, it is endowed with a physical and mathematical theory that fournished the base of a precisely physical measure, by the intermediary of pendulum laws that allowed the application of this instrument in pratical goals, as the determination of longitudes and the construction of a pendulum clock

Full textAbstract:
The relationship between science and theology in Galileo’s work is usually studied with reference to the Copernican letters and the so-called ‘Galileo affair,’ ended with Galileo’s abjuration in 1633. This dissertation tackles the same subject, but from a different angle. Galileo’s approach to the creation theme does indeed allow us to inquiry into the relationship between science and theology while keeping Biblical exegesis and Galileo’s trial on the background. The dissertation is divided into two parts: (1) “Creation,” and (2) “Cosmogony.” In the first part, a series of primary sources are considered (Benedetto Castelli’s letter to Galileo of April the 1st, 1607; a few unpublished folios from the reportationes of Muzio Vitelleschi’s course on natural philosophy held at the Roman College in 1589-90; some passages of Galileo’s Juvenilia) which help us gauge, albeit indirectly, Galileo’s attitude toward the possibility of demonstrating creatio de novo (the beginning of the world) and creatio ex nihilo (the existential dependence of creatures on God). Although some initial supporters of Galileo sought to demonstrate creatio de novo through his definition of motion, he never welcomed their attempt. He probably agreed with Castelli that the demonstration of creatio de novo was beyond the reach of his science and, in general, of human knowledge (a position that, for the sake of convenience, I have referred to as ‘agnosticism’). As regards creation out of nothing, at Galileo’s time this notion was usually treated in light of a metaphysical understanding of the relationship between God and creatures – a relationship which entailed an understanding of God as primum ens (first being). This notion is also used in the Juvenilia, namely, a series of pages reporting standard arguments of Scholastic philosophy, which Galileo copied from other sources. I have interpreted the total absence of the idea of God as primum ens in the original writings of Galileo as a sign that Galileo was not interested in the problem of creatio ex nihilo, nor did he consider its metaphysical solution. In the second part, I have argued that Galileo was interested in the cosmogony problem, namely, he tried to understand how God imposed order on the primeval chaotic universe. Cosmogony was refuted in the Aristotelian tradition on the basis that motion and gravity cannot be conceived of out-side the orderly framework of the universe. In this view, mechanics leans on cosmology, and vice versa. Galileo separates the two, but through cosmogony he tries to reconcile his cosmological views (initially geocentric, then heliocentric) with his understandings of motion and gravity. Thanks to Copernicus, he is able to ‘mathematize’ the cosmogony problem. Thus, the solution to this problem becomes an important scientific task, one that allows Galileo to advocate the relevance of his science on a universal scale.

A presente tese tem por objetivo o estudo das estratégias de polidez empregadas em situações conflituosas no texto teatral Leben des Galilei de Bertolt Brecht. O conceito de conflito foi definido como uma situação de discordância a partir de choque de interesses e/ou opiniões a respeito de um tema abordado. A partir deste conceito, foram extraídos seis fragmentos da referida peça nas quais se observavam tal situação e a eles foram aplicadas as bases teóricas elencadas para o trabalho. Para atingirmos nosso objetivo, consideramos as teorias de trabalho da face elaboradas por Goffman, as estratégias de polidez postuladas por Brown & Levinson. Ao longo da pesquisa, a argumentação mostrou-se importante para a análise e, portanto, recorremos aos pressupostos da teoria da argumentação segundo estudos de Perelman & Olbrechts-Tyteca. Com as análises, foi possível identificar, respectivamente, um grande número de estratégias de polidez positiva, relativamente pouca freqüência de polidez negativa, ocorrência de estratégias off record utilizadas principalmente no uso agressivo do trabalho da face e ocorrências bald on record dentro do esperado. Quanto à argumentação, constata-se presença maciça de razões e exemplos e grande uso de perguntas retóricas e argumento de autoridade.This study aims to investigate politeness strategies used in conflict situations in the play Leben des Galilei by Bertolt Brecht. Conflict was defined as a situation of discordance arising from a clash of interests or opinions about a given theme. Six fragments of the play presenting such a situation were selected and analyzed according to the theories of face-work by Goffman and politeness strategies by Brown and Levinson. Due to the importance it assumed during the research, fundamentals of argumentation by Perelman & Olbrechts-Tyteca were also brought into the theoretical basis. The analysis has identified a high frequency of strategies for positive politeness, relatively few strategies for negative politeness, off-record strategies used mainly for aggressive face-work purposes and bald on record occurrences within the expected range. Regarding argumentation, reasons and examples are abundantly provided and rhetorical questions and authority arguments largely used.

A pesquisa concentra-se no processo de entabulação de Vincenzo Galilei e em como o alaudista o relacionava à teoria musical da época. O tratado Fronimo foi escolhido por ser o texto em que Galilei descreve essa relação. O trabalho baseia-se nas principais características do processo de entabulação de Galilei, comparando-o com os processos de alguns outros tratados de entabulação da época. Para compreender como o processo de entabulação se relaciona com as teorias composicionais do século XVI, pesquisou-se dentro dos principais tratados da época as características que se relacionavam com o processo. Por fim, propõe-se uma forma de análise histórica baseada tanto no processo de entabulação como na teoria musical do período. Como exemplo, foi feita a análise da entabulação feita por Galilei e publicada no Fronimo de Io mi son giovinetta de Domenico Ferrabosco.
This research is centered in Vincenzo Galilei´s lute intabulation process and in how it was related to sixteenth-century music theory. Fronimo was chosen because it is the treaty in which Galilei describes this relationship. A description of the intabulation process´primary characteristics is compared to other forms of lute intabulation described by other authors from the same century. Next, the compositional theories relevant to the analysis of the music is selected based on the characteristics of the intabulation process. Finally, we offer a form of historic analysis for intabulations based on the relation between Galilei´s process and sixteenth-century compositional theory. As an example an analysis of Galilei´s intabulation of Domenico Ferrabosco´s Io mi son giovinetta was made.

Enquanto que os animais do grupo 2 (n=13), aos cinco (M5), oito (M8), doze (M12) e quatorze (M14) meses de idade. Considerando os estados refrativos da curvatura anterior e da ceratometria corneana total verificou-se diminuição progressiva (aplanamento) ao longo do primeiro ano de vida dos coelhos com tendência a estabilização em M12. De modo contrário, na curvatura posterior foi observado aumento com estabilização no M5. Na espessura corneana houve aumento até M4 e posterior estabilização do M5 ao M12 com aumento não significativo entre M12 e M14. Quanto ao volume e profundidade de câmara anterior verificou-se correlação positiva com a idade, e estabilização aos quatro meses de idade. O uso do sistema duplo Scheimpflug e disco de plácido possibilitou identificar a influência da idade sobre o estado de refração da córnea, tanto em sua curvatura como espessura em coelhos durante a fase de crescimento, bem ...

Abstract: The aim of this study was to describe the keratometric changes of anterior and posterior corneal curvatures, total keratometry, corneal thickness, volume and depth of the anterior chamber, during rabbit growth phase through the combined system of Placido disc and two Scheimpflug cameras. For this purpose, were studied 28 rabbits (Oryctolagus cuniculus) of the Botucatu genetic group randomly assigned to two experimental groups. Animals of group 1 (n = 15) were evaluated at two (M2), three (M3), four (M4) and five (M5) months of age. While the animals in group 2 (n = 13), at five (M5), eight (M8), twelve (M12) and fourteen (M14) months of age. Refractive states of anterior curvature and corneal keratometry showed a progressive decrease (flattening) throughout the first year of life of rabbits presenting a tendency to stabilize in M12. On the other hand, an increase of the posterior curvature was observed with stabilization in M5. Corneal thickness presented an increase until M4 and subsequent stabilization of M5 to M12 with a non significant increase between M12 and M14. As to the anterior chamber volume and depth, there was a positive correlation with age, and stabilization at four months of age. Therefore, the use of the Double Scheimpflug system and Placido disc allowed to identify the influence of age on the refractive state of the cornea, both in its curvature and thickness in rabbits during the growth phase, as well as in volume and depth of the anterior chamber.

S’interroger sur la clef de lecture à assumer pour aborder l’interprétation et l’analyse du premier écrit de Kant,présuppose en même temps de se poser le problème du fil conducteur qui traverse toute la recherche philosophique et scientifique de Kant. La reconstruction systématique et archéologique de la recherche spéculative kantienne pourra donc révéler, déjà à partir des Gedanken, une étude entièrement finalisée à la poursuite [I.] d’une description systématique del’univers (comme connaissance ‘objective’ du monde extérieur et intérieur, materialiter e formaliter spectata) [II.] antécédemment déterminée (comme connaissance ‘subjective’, materialiter e formaliter spectata) [III.] selon la ligne programmatique propre à la Science ‘classique’.Un tel gain a donc permis : (1.) de révéler avant tout l’origine aristotélicienne de la querelle des forces vives ; (2.) de jeter une lumière nouvelle sur la première formation de la pensée de Kant, révélant en outre les sources kantiennes orthodoxes établies par l’historiographie philosophique (c’est-à-dire Descartes, Leibniz et Wolff) comme apparentes par rapport à la perspective assumée par le parcours kantien, davantage tourné quant à lui vers les problèmes ouverts de la mise en cause du modèle physique aristotélicien par Galilée et de ceux émergeant de la tentative d’unification systématique proposée par Newton ; (3.) de trouver enfin, dans la solution kantienne, la clef de voûte pour dépasser définitivement le dualisme épistémologique (d’où l’incongruité conséquente), aujourd’hui subsistante, entre le modèle einsteinien dans le continu et le modèle, discret et probabiliste, proposée par la Mécanique quantiqueAsking ourselves about the interpretative framework that we should adopt when we set out to read and examine Kant’s first oeuvre demands that we pose the preliminary question of whether a red thread recurs throughout Kant’s philosophical and scientific investigation. A reconstruction of Kant’s theoretical investigation reveals that Kant’s inquiry, beginning with the Gedanken, is entirely devoted to accomplish (I) a systematic description of the universe (understood as objective knowledge of the external and internal world, a knowledge that is viewed both materially and formally, materialiter and formaliter spectata); (II) an antecedently determined description of the universe (understood as subjective knowledge, a knowledge that is viewed both materially and formally, materialiter and formaliter spectata); and (III) a description of the universe that is carried out within the programmatic direction proper of ‘classic’ Science. Our research findings allowed us to (1) show that the question of ‘living forces’ has Aristotelian underpinnings; (2) shed new light on the first development of Kant’s thought and show that the orthodox Kantian sources (that is, Descartes, Leibniz e Wolf) depart from Kant’s philosophical project which was primarily concerned with the problems that resulted from the crisis of Aristotelian science due to Galileo’s contributions and Newton’s attempt at a systemic unification of nature; (3) finally, identify a Kantiansolution for overcoming the epistemological dualism (and the incompatibility thereof) between Einstein’s model of a continuum in nature and the Quantum Mechanical model that describes nature as discrete and probabilistic

Full textAbstract:
Galilée (1564-1642) a introduit dans son Il Saggiatore (1623) une nouvelle conception du corps. L’ontologie et la théorie de la connaissance des corps de Spinoza peuvent être conçues comme une réponse à Galilée. En effet, le philosophe hollandais répète de nombreuses fois que les qualités sensibles n’appartiennent pas aux corps en soi. En outre, il précise que les idées des affections sont des idées inadéquates qui représentent plutôt le corps affecté que les corps affectants. Néanmoins, Spinoza (1632-1677) donne une interprétation tout à fait particulière de cette conception galiléenne. Comme il le précise dans sa définition de l’Abrégé de physique, un corps en soi est un ensemble de parties qui sont unies par un rapport mutuel de mouvement et de repos. Ce ratio est à concevoir comme une nature, une proportion ou une loi physique d’un corps. Par sa nouvelle conception du corps, Galilée a dépassé la distinction ontologique entre les corps artificiels et les corps naturels, ouvrant la voie à l’application des modèles et des analogies. A première vue, Spinoza n’applique pas le modèle du pendule. Néanmoins, une étude plus détaillée dévoile l’importance de la physique de l’horloge pendulaire (inventée par Galilée et perfectionnée par Chr. Huygens) dans la conception spinoziste du corps. Dans sa définition du corps de l’E1, Spinoza conçoit le corps dans sa relation avec l’essence de Dieu. Néanmoins, dans sa CM, il a introduit le conatus ou l’essence d’une chose en donnant le paradigme d’un corps en mouvement. Comme Galilée l’avait démontré, le mouvement est essentiellement une force. Spinoza a généralisé cette idée de force, comme il l’a fait avec l’idée de loi de la natureIn Il Saggiatore (1623), Galileo (1564-1642) introduced a novel conception of the body. Spinoza’s ontology and epistemology can be viewed as original responses to this. Indeed, the author of the Ethics writes repeatedly that sensible qualities do not belong to the body as such. Moreover, he clearly states that the ideas of affections are inadequate, representing much less the intrinsic properties of external bodies than the affected body itself. However, Spinoza (1632-1677) gives a very particular interpretation of the Galilean conception. As he makes clear in his Physical Interlude, a body consists in a group of parts united by a mutual relation of motion and rest. Furthermore, this relation is to conceived as a nature, proportion or physical law of the body. By means of his new conception, Galileo radically upended the ontological distinction between artificial and natural bodies, which opened the door to the application of models and analogies for the explanation of natural phenomena. At a first glance, Spinoza does not apply the model of the pendulum clock, which was a leading model of the 17th century. However, a closer look reveals the importance of the physics of the pendulum clock (invented by Galileo and perfected by Christian Huygens) for Spinoza’s conception of the body. In his definition in E1, Spinoza conceives of the body in its relation to the essence of God. In his CM, however, he had introduced the conatus, or the essence of a thing, in terms of the paradigm of the body in motion. As Galileo had shown, motion is essentially a force. Spinoza generalized this notion of force, just as he generalized the idea of the law of nature

In this thesis, we aim to conduct a study and reconstruction of the criticism that Galileo undertakes to physics and cosmology of Aristotle, and works as an anchor Sidereus Nuncius and First Day of Dialogue Concerning the Two Chief World Systems. The arguments developed by Italian physicist these works, consolidating the Copernican theory and revolutionize the way we study nature. For centuries, the Western conception of the universe was supported by the assumptions of cosmology of Aristotle. Aristotelian cosmology had as fundamental points the idea of the incorruptibility of the heavens, the earth and the immobility of a hierarchy of elements. For the peripatetic, the cosmos was finite and heterogeneous, and was divided into two distinct regions: the sublunary (terrestrial) and above the Moon (heavenly). The telescopic observations made by Galileo in 1609, showing craters and mountains on the moon and Jupiter's satellites, were in evidence against the heaven-earth dichotomy proposed by Aristotle. For it revealed "imperfections" in the heavenly bodies, and showed that not all the stars had their revolutions as the center of the Earth, the idea of asking the same centrality in the cosmos. Moreover, the break with Aristotelian cosmology destabilizing the very physics of Aristotle, whose explanation of the movements of bodies depended on the cosmological structure, since there were three types of moves, straight toward the center, straight away from the center and circular around the center, which required a motionless earth occupying the center of the cosmos. The idea of centrality and immobility of the Earth is therefore fundamental point of Aristotelian physics and cosmology. Most of the work of Galileo Galilei seems to think about a central objective: the defense of the Copernican theory. Since his public adhesion to the Copernicanism in 1610, in Sidereus Nuncius, until Dialogue published in 1632, the Pisan Phisycist sought to break with the assumptions of the Aristotle s natural philosophy which supported the geocentric conception. As a result, it is in First Day of Dialogue that, certainly, we could find a more systematic and focused effort against the Aristotelic conception of world and its main characteristic: the dissociation of the cosmos into two distinct regions, the celestial and sublunary.
Nesta dissertação, temos como objetivo realizar um estudo e reconstrução das críticas que Galileu empreende à física e à cosmologia de Aristóteles, tendo como âncora as obras Sidereus Nuncius e Primeira Jornada do Diálogo sobre os dois máximos sistemas do mundo. Os argumentos desenvolvidos pelo físico pisano nestas obras, consolidam a teoria copernicana e revolucionam a maneira de se estudar a natureza. Durante séculos, a concepção ocidental de universo esteve apoiada nos pressupostos da cosmologia de Aristóteles. A cosmologia aristotélica tinha como pontos fundamentais a ideia de incorruptibilidade do céu, de imobilidade da Terra e de uma hierarquia dos elementos. Para o peripatético, o cosmos era finito e heterogêneo, e se encontrava dividido em duas regiões distintas: a sublunar (terrestre) e a supralunar (celeste). As observações telescópicas realizadas por Galileu em 1609, ao mostrar crateras e montanhas na Lua, e satélites em Júpiter, constituíram-se em evidências contrárias à dicotomia céu-Terra proposta por Aristóteles. Pois revelavam imperfeições nos corpos celestes, e mostravam que nem todos os astros tinham como centro de suas revoluções a Terra, questionando a ideia de centralidade da mesma no cosmos. Além disso, a ruptura com a cosmologia aristotélica desestabilizava a própria física de Aristóteles, cuja explicação dos movimentos dos corpos dependia da estrutura cosmológica, uma vez que existiam três tipos de movimentos: retilíneo em direção ao centro, retilíneo se afastando do centro e circular em torno do centro, o que requeria uma Terra imóvel ocupando o centro do cosmos. A ideia de centralidade e imobilidade da Terra é, portanto, ponto fundamental da física e da cosmologia aristotélicas. Grande parte da obra de Galileu parece girar em torno de um objetivo central: a defesa da teoria copernicana. Desde a sua adesão pública ao copernicanismo em 1610, no Sidereus Nuncius, até o Diálogo publicado em 1632, o físico pisano buscou romper com os pressupostos da filosofia natural de Aristóteles que sustentavam a concepção geocêntrica. Com efeito, é na Primeira Jornada do Diálogo que poderemos encontrar um esforço mais sistemático e concentrado contra a concepção aristotélica de mundo e sua principal característica: a dualidade do cosmos.

O Galileo será o primeiro sistema de navegação global por satélite da União Européia. Além de disponibilizar dois sinais de acesso livre o Galileo irá oferecer serviços para diferentes segmentos tais como: aplicações comerciais; serviços de busca e resgate; serviços governamentais; e segurança de vidas. Tais serviços, baseados em uma constelação GPS (Global Positioning System) não são possíveis hoje. O objetivo deste estudo é a implementação de um receptor em software (Software Defined Radio - SDR) para o sinal Galileo E1-B com enfoque na geração deste sinal e nas etapas de aquisição e rastreamento. Algumas características da antena receptora, do hardware do estágio de entrada (Front-End) e considerações sobre a digitalização do sinal E1-B são descritas assim como as características dos blocos que compõem as etapas de aquisição e de rastreamento. Através destas etapas o sinal espalhado espectralmente é demodulado e os bits de navegação são recuperados.O Galileo ainda está em sua fase de implementação. Diante disto, foi necessário um trabalho extensivo de pesquisa objetivando o levantamento de suas principais características, dando enfoque ao sinal E1-B. Este sinal utiliza uma nova técnica de modulação aplicada à navegação, denominada BOC (Binary Offset Carrier), alterando assim algumas características da estrutura de processamento de um receptor GNSS convencional. Esta nova técnica utiliza uma subportadora que divide o espectro em dois lóbulos principais com um nulo na freqüência de portadora permitindo a coexistência espectral com sinais GNSS que operem na mesma freqüência de portadora do sinal E1-B além de permitir o rastreamento do sinal em ambientes com baixa relação portadora-densidade de ruído (C/No) devido ao estreitamento da função de autocorrelação.

Indeed, more than ten years folowing the opening up to civilians of satellite-based navigation systems initially designed for military purposes, civil satellite navigation applications are becoming more and more numerous. The potential benefits have proven enormous in terms of transport safety and efficiency as well as for non-transport-related industries.Dans les toutes prochaines années, les systèmes globaux de navigation par satellite (GNSS) feront partie intégrante de notre vie quotidienne.

Les systèmes mondiaux de navigation par satellite (GNSS) sont de plus en plus présents dansnotre vie quotidienne. Des nouveaux utilisateurs émergent avec des besoins opérationnelssupplémentaires, ce qui implique une évolution constante des systèmes de navigation actuels.Dans le cadre de Galileo (système GNSS européen) et en particulier dans Galileo E1 OpenService (OS), l’addition d’un nouveau signal d’acquisition pourrait contribuer à améliorer larésilience dans la phase d’acquisition et à réduire le temps pour géo-localiser notre récepteur(TTFF). La conception d'un nouveau signal GNSS est toujours un compromis entre plusieursfigures de mérite. Les plus pertinents sont la précision de la position, la sensibilité de récepteur etle TTFF. Cependant, si l’on considère que la phase d’acquisition du signal le principal objectif, lasensibilité et le TTFF ont une pertinence plus grande. Compte tenu de ce qui précède, dans cettethèse, il est présenté la conception conjointe d'un signal GNSS avec la structure de message afinde proposer un nouveau signal Galileo de deuxième génération, qui offre bonne sensibilité derécepteur ainsi que une réduction dans le TTFF. Plusieurs aspects ont été abordés afin deconcevoir la nouvelle composante de signal. Premièrement, la définition de la modulation doitprendre en compte la compatibilité des fréquences radioélectriques afin de provoquer un niveaude brouillage acceptable dans la bande. De plus, la modulation devrait fournir de bonnespropriétés de corrélation et une bonne résistance contre les multi trajets afin d'améliorer lasensibilité du récepteur. Deuxièmement, le choix du nouveau code PRN est également crucialpour faciliter la phase d’acquisition. Un critère de modélisation basé sur une fonction de coûtpondéré est utilisé pour évaluer la performance des codes PRN. Cette fonction de coût considèredifférent facteurs telles que l'autocorrélation, la corrélation croisée et la densité spectrale depuissance. Troisièmement, une conception conjointe entre la structure de message et le schémade codage de canal peut fournir à la fois une réduction du TTFF et une amélioration de larésilience des données décodées. Alors, une nouvelle méthode de conception de la structure demessage et du schéma de codage de canal pour le nouveau signal est proposée. Cette méthodefournit les instructions pour concevoir une structure de message dont le schéma de codage decanal est caractérisé pour les propriétés full diversity, maximum distance separable et ratecompatibility. Le codage de canal est essentiel pour améliorer les performances de démodulationde données, en particulier dans les environnements très obstrué ou avec d’interférences.Cependant, ce processus peut être très sensible au calcul correct de l'entrée du décodeur. Desaméliorations significatives ont été obtenues en considérant «soft » décodeurs, via le calcul deslog-likelihood ratio (LLR). Malheureusement, la connaissance complète des informations d'état ducanal (CSI) était généralement prise en compte, ce qui est rarement le cas dans des scénariosréels. Dans cette thèse, nous fournissons de nouvelles méthodes pour calculer desapproximations linéaires du LLR, sous les canaux de fading et interférence, en considérantcertaine information statistique sur le CSI. Finalement, transmettre un nouveau signal dans lamême fréquence porteuse et en utilisant le même amplificateur de puissance (HPA) génère descontraintes dans les méthodes de multiplexage, car une enveloppe constante ou quasi constanteest nécessaire pour réduire les distorsions non linéaires. Également, la conception dumultiplexage devrait offrir une efficacité énergétique élevée afin de ne pas gaspiller l'énergietransmis du satellite. Considérant le précédent, dans cette thèse, nous évaluons différentesméthodes de multiplexage, qui cherchent l’intégration de un nouveau signal binaire dans la bandeGalileo E1Global Navigation Satellite System (GNSS) are present in our daily lives. Moreover, new users areemerging with further operation needs involving a constant evolution of the current navigationsystems. In the current framework of Galileo (GNSS European system) and especially within theGalileo E1 Open Service (OS), adding a new acquisition aiding signal could contribute to providehigher resilience at the acquisition phase, as well as to reduce the time to first fix (TTFF).Designing a new GNSS signal is always a trade-off between several performance figures of merit.The most relevant are the position accuracy, the sensitivity and the TTFF. However, if oneconsiders that the signal acquisition phase is the goal to design, the sensitivity and the TTFF havea higher relevance. Considering that, in this thesis it is presented the joint design of a GNSS signaland the message structure to propose a new Galileo 2nd generation signal, which provides ahigher sensitivity in the receiver and reduce the TTFF. Several aspects have been addressed inorder to design a new signal component. Firstly, the spreading modulation definition must considerthe radio frequency compatibility in order to cause acceptable level of interference inside the band.Moreover, the spreading modulation should provide good correlation properties and goodresistance against the multipath in order to enhance the receiver sensitivity and to reduce theTTFF. Secondly, the choice of the new PRN code is also crucial in order to ease the acquisitionphase. A simple model criterion based on a weighted cost function is used to evaluate the PRNcodes performance. This weighted cost function takes into account different figures of merit suchas the autocorrelation, the cross-correlation and the power spectral density. Thirdly, the design ofthe channel coding scheme is always connected with the structure of the message. A joint designbetween the message structure and the channel coding scheme can provide both, reducing theTTFF and an enhancement of the resilience of the decoded data. In this this, a new method to codesign the message structure and the channel coding scheme for the new G2G signal isproposed. This method provides the guideline to design a message structure whose the channelcoding scheme is characterized by the full diversity, the Maximum Distance Separable (MDS) andthe rate compatible properties. The channel coding is essential in order to enhance the datademodulation performance, especially in harsh environments. However, this process can be verysensitive to the correct computation of the decoder input. Significant improvements were obtainedby considering soft inputs channel decoders, through the Log Likelihood Ratio LLRs computation.However, the complete knowledge of the channel state information (CSI) was usually considered,which it is infrequently in real scenarios. In this thesis, we provide new methods to compute LLRlinear approximations, under the jamming and the block fading channels, considering somestatistical CSI. Finally, to transmit a new signal in the same carrier frequency and using the sameHigh Power Amplifier (HPA) generates constraints in the multiplexing design, since a constant orquasi constant envelope is needed in order to decrease the non-linear distortions. Moreover, themultiplexing design should provide high power efficiency to not waste the transmitted satellitepower. Considering the precedent, in this thesis, we evaluate different multiplexing methods,which search to integrate a new binary signal in the Galileo E1 band while enhancing thetransmitted power efficiency. Besides that, even if the work is focused on the Galileo E1, many ofthe concepts and methodologies can be easily extended to any GNSS signal

Погурельський Олексій СергійовичСтаном на початок 2020 року в світі функціонує 4 глобальних навігаційні супутникові системи. Кожна з них є реалізацією складної в технічному і затратної в фінансовому плані задачі. Глобальна супутникова навігаційна система це не лише сузір’я супутників але і складна наземна інфраструктура розподілених по земній поверхні станцій моніторингу та спостереження, прийому та завантаження спеціальної службової інформації, головний та резервний центри управління. Через цю складність реалізувати перші системи вдалося потужним країнам, чий військовий бюджет осилив цей тягар: Сполученим Штатам Америки (система GPS), Радянському Союзу на початковому етапі і Російській Федерації на завершальному (система ГЛОНАСС), а також Китайській Народній Республіці (система BeiDou). [2, 3, 11] Спільним у створенні цих систем була мета – забезпечення потреб військової сфери у високоточному глобальному сервісу позиціонування та наведення. Широке розповсюдження технологій супутникової навігації в цивільній сфері було лише похідною від тих можливостей які забезпечили розгорнуті системи військовим. Розвиток і основні віхи в становленні систем глобального позиціонування були пов’язані з політичним протистоянням на світовій арені. Як наслідок, на сьогоднішній день можна констатувати факт наявності надзвичайно зручних і ефективних засобів для глобального позиціонування, які при цьому не надають жодних гарантій цивільним користувачам на наявність і доступність своїх сигналів і сервісів у майбутньому. [4, 11, 12] Створення і розгортання глобальної навігаційної супутникової системи повністю цивільного призначення значно відрізняє на цьому тлі європейський проект Galileo. Він пройшов складний шлях від ідеї і загальної концепції до свого нинішнього етапу, коли система стоїть на порозі повноцінного функціонування з досягнутою номінальною кількістю космічних апаратів. Орієнтована на потреби цивільних і перш за все авіаційних користувачів, система Galileo забезпечуватиме доступ до сигналів високоточної навігації на комерційній основі зі збереженням безкоштовних відкритих сервісів. [5,19] Поточна стадія функціонування системи Galileo дозволяє планувати і виконувати комплексні дослідження її характеристик в режимі одно системної обробки даних та у сполучені з даними від інших існуючих систем. Завдяки організації довготривалого моніторингу з’являється можливість відслідковувати еволюційні зміни, які відбуватимуться в системі разом з нарощуванням кількості супутників на орбіті. Ці задачі можуть бути продовженням результатів одержаних в цій роботі, присвяченій оцінці точності глобальної навігаційної супутникової системи Galileo.

The Intel Galileo, inspired by the well-known Arduino board, is a development board with many possibilities because of its strength. The Galileo is has an Intel processor capable of running GNU/Linux and can be connected to the internet, which opens up the possibility to be controlled remotely. The programming language that comes with the Intel Galileo is the same as for the Arduino development boards, and is therefore very limited and does not utilize the Galileo’s entire strength. Our aim with this project is to integrate a more suitable programming language; a language that can make better use of the relatively powerful processor to control the components of the board. The programming language of choice is Erlang, and the reason is obvious. Erlang can be described as a process-oriented programming language based on the functional programming paradigm and its power in concurrency. The result of the project was the successful integration of a complete version of GNU/Linux on the board and the cross-compilation of Erlang/OTP onto the board. Having Erlang running on the system opens up many possibilities for future work, amongst all: creating Erlang programs for the Intel Galileo, integrating an effective API, and measuring the pros and cons of using Erlang on an Intel Galileo.Intel Galileo är ett utvecklingskort som bygger på Arduinos succe. Den kommer med en kraftigare processor jämfort med Arduino Uno, och den har möjlighet att kunna köra GNU/Linux. Den har också en port för att kunna kopplas till internet och på så sätt kommunicera med andra enheter. Programmeringsspråket som rekommenderas för Intel Galileo är densamma som används för Arduinos utvecklingskort. Det finns däremot en möjlighet att kunna kombinera utvecklingskortet med ett programmeringsspråk som kan erbjuda mer funktionalitet och fortfarande vara enkelt. Vårt val hamnade på Erlang för den är ett funktionellt språk och har möjlighet att hantera olika processer. Tanken är att kunna behandla olika komponenter kopplade till utvecklingskortet som processer, som kan kommunicera med andra komponenter och med internet. Projektarbetet bestod av att undersöka ifall det är möjligt att kunna kombinera Erlang/OTP med Intel Galileon samt skriva en guide för hur implementeringen gick till. Att kombinera de två var lyckat och det öppnar upp möjligheter för fortsätta arbeten och försök.

Full textAbstract:
Aux XVIIIe et XIXe siècles, les historiens des sciences associaient généralement Francis Bacon et Galilée pour leur rôle dans l’émergence de la science moderne, mais, à la fin du XIXe et au début du XXe siècle, la Révolution scientifique fut identifiée de manière stricte à la construction de la physique mathématique, ce qui eut souvent pour conséquence de rejeter Bacon hors de l’histoire des sciences. Nous reprenons l’étude conjointe de ces deux auteurs pour mesurer quelle est exactement la nature de leur divergence. Dans la première partie de notre travail, nous abordons les questions cosmologiques. Sur quels arguments Galilée fonde-t-il sa défense publique du copernicianisme entre 1610 et 1616, jusqu’à la première condamnation de l’opinion copernicienne par l’Eglise Catholique ? Pour quelles raisons Bacon, qui suit cette campagne copernicienne, rejette-t-il la plupart des découvertes astronomiques de Galilée ? Pourquoi Bacon, tout en réussissant à percevoir le caractère (trop peu) systématique du géocentrisme, refuse-t-il l’héliocentrisme ? Dans la deuxième partie de notre travail, nous abordons les questions relatives à la méthode, ainsi que les théories de la matière et du mouvement. Quel est le rôle de la perception sensible et la fonction des mathématiques dans les théories de Bacon ? Quelle est la signification de sa théorie du mouvement, qui multiplie les objets d’étude en proposant une typologie des différents mouvements concrets, alors que la physique mathématique tend à réduire tout déplacement au seul mouvement linéaire inertiel ? Quelle est la fonction de l’atomisme mathématique de Galilée ? Dans quelle mesure sa science du mouvement se distingue-t-elle de l’approche baconienne ? La différence fondamentale entre la science galiléenne et la démarche de Bacon consiste, selon nous, dans la nature des expériences et des observations qui sont convoquées, ainsi que dans le type d’abstraction que ces deux auteurs veulent conférer à la philosophie naturelleDuring the eighteenth and nineteenth centuries, historians of science usually considered that Francis Bacon and Galileo had respectively played their role in the merging of modern science, but, at the end of the nineteenth and the beginning of the twentieth century, Scientific Revolution has been strictly reduced to the elaboration of mathematical physics, which had for consequence to exclude Bacon from the history of science. Our aim is to underline the exact nature of the difference between those two authors. In the first part, we deal with the cosmological problems. What arguments did Galileo produce to sustain his public commitment for the Copernican system, from 1610 to 1616, until the first condemnation of copernicanism by the Roman Church ? For what reasons did Bacon reject most of Galileo’s astronomical discoveries ? Why Bacon, who clearly perceived the fact that the geocentric theory lacked systematic character, refused heliocentrism ? In the second part, we deal with the methodological questions, we analyse matter theories and the science of motion. What is the role of sense perception and what is the fonction of mathematics in Bacon’s theories ? What is the significance of his theory of motion, which multiplies the objects of study, proposing a typology of concrete movements, while mathematical physics aims at reducing any motion to the rectilinear inertial movement ? What is the fonction of the mathematical atomism proposed by Galileo ? In what measure does his science of motion distinguish from the baconian approach ? We think that the fondamental difference between the science of Galileo and the theories of Bacon consists in the nature of the experiments and observations used, and in the type of abstraction they are looking for in natural philosophy
