Lacan, Gödel, a ciência e a verdade

Jaques Lacan, the thinker who proposes a return to the fundamentals of psychoanalysis in Freud states that the math would face as a privileged way of transmission of knowledge by the science. Although he was a follower of the mathematization of nature as the foundation of modern science, for him this principle does not imply eliminating the subject that produces it. That would be equivalent to saying that there can not be a language, whatever, even the math, that may "erases" the subject assumption in science. In the text The science and the truth we will try to introduce the idea, not so simple, by the way, the truth as the cause. Citing the framework of the causes in Aristotle, Lacan will speak of a homology between the truth as formal cause, in the case of science, and the truth as material cause, on the side of psychoanalysis. Among its aims with this text, he wants to establish that the unconscious of the subject would be none other than the subject of science. The famous incompleteness theorems of logical-mathematical Kurt Gödel enter here as a chapter of this issue. Recognized as true watershed, these theorems have to be remembered as revealing even outside the mathematical environment, and Lacan himself is not indifferent to this. He makes mention of Gödel's name and draws some observations apparently modest support for his own theory. Since some technical sophisticated knowledges awaits the reader who intends understand this supposed corroboration that Gödel provides to psychoanalysis, introduce the student of Lacan in the use he makes of the incompleteness theorems is the objective of this work. In The science and the truth, which fits us to locate the name of Gödel, one must question how seize such an idea without incurring the extrapolation and abuse of mathematical knowledge, almost trivial in this case. Thus, this paper aims to introduce the reader to the reasoning behind the theorems of Gödel, acquaint him about the Lacan’s mathematical claims, and indicate how to proceed using this implicit math in the text The science and the truth.

Studies on betanin natural dye incorporated ZnO composites at nano and micro scale for photonic device applications

Green energy and Green technology are the most of the quoted terms in the context of modern science and technology. Technology which is close to nature is the necessity of the modern world which is haunted by global warming and climatic alterations. Proper utilization of solar energy is one of the goals of Green Energy Movement. The present thesis deals with the work carried out in the eld of nanotechnology and its possible use in various applications (employing natural dyes) like solar cells. Unlike arti cial dyes, the natural dyes are available, easy to prepare, low in cost, non-toxic, environmentally friendly and fully biodegradable. Looking to the 21st century, the nano/micro sciences will be a chief contributor to scienti c and technological developments. As nanotechnology progresses and complex nanosystems are fabricated, a growing impetus is being given to the development of multi-functional and size-dependent materials. The control of the morphology, from the nano to the micrometer scales, associated with the incorporation of several functionalities can yield entirely new smart hybrid materials. They are special class of materials which provide a new method for the improvement of the environmental stability of the material with interesting optical properties and opening a land of opportunities for applications in the eld of photonics. Zinc oxide (ZnO) is one such multipurpose material that has been explored for applications in sensing, environmental monitoring, and bio-medical systems and communications technology. Understanding the growth mechanism and tailoring their morphology is essential for the use of ZnO crystals as nano/micro electromechanical systems and also as building blocks of other nanosystems.

El copernicanismo en las Españas del XVI y el XVII. Ciencia, filosofía y literatura.

In 1543 Nicolas Copernicus published his Revolutionibus Orbium's Coelelestium. This is the scientific work that gave birth to modern science, something thoroughly European, since scientists of different countries contributed to it: Poland, Italy, Germany, Spain, France, Holland, etc. A work that appeared in a crucial moment obviously represented the need of that time to correct the Julian calendar. A new procedure to calculate the positions of the stars was necessary for astrology and for the making of predictions that were important at that time. Our intention is to outline the history of how it was introduced in Spain at the beginning of the scientific revolution. We will not conceal that Spain has been a country that has only contributed to scientific literature in a deficient way, maybe we can offer some arguments that help to understand why this has happened.

Natureza, linguagem e racionalidades: contribuições para uma hermenêutica ambiental

A presente dissertação parte do problema sobe a possibilidade de compreender uma racionalidade não instrumental, em relação à dominação técnica e científica da natureza para pensar a Educação Ambiental. A pesquisa teve como principais objetivos compreender e interpretar a Natureza e a Educação Ambiental para alem do sentido historicamente produzido pela ciência sobre a relação homem e natureza em confronto com outras interpretações oriundas de uma visão ampliada de racionalidade. Propõe-se a desconstrução por meio de um exercício hermenêutico da concepção de natureza e forma de agir proposta pela ciência moderna como propósito de desvendar o caráter ideológico da ciência e dos múltiplos usos que carrega o conceito. A investigação permitiu identificar aspectos críticos da racionalidade que se desenvolveu no mundo ocidental e tem causado inúmeros problemas ao meio ambiente e à sobrevivência da natureza e da espécie humana. A presente Dissertação foi pensada na proposta de radicalização da ideia de compreensão como interpretação, de modo a apresentar como método de produção de conhecimento a interpretação narrativo-interpretativa proposta pela hermenêutica.

La question de l'histoire chez Husserl

Ce présent mémoire porte sur la conception historique de la phénoménologie dans le dernier ouvrage de Husserl, La crise des sciences européennes et la phénoménologie transcendantale (1937). Le chapitre 1 avance, qu’il n’y a pas, du point de vue de ses motifs internes, de « tournant historique » de la phénoménologie. Le projet d’une théorie transcendantale de l’histoire doit se comprendre comme étant l’aboutissement nécessaire de la pensée husserlienne. Le chapitre 2 s’intéresse à la manière par laquelle la phénoménologie serait censée renouveler l’identité collective de l’Europe et résoudre la séparation entre la pensée et l'action. La phénoménologie, à partir d’une critique de l’objectivisme des sciences, serait la réalisation du telos de la pensée moderne. Cependant, l’exigence d’authenticité de Husserl s’avère insuffisante pour parvenir à une juste compréhension des implications de la responsabilité. Bien que cette visée humaniste soit d’un intérêt évident, elle s’avère trop rudimentaire.

Beyond conservation agriculture.

ABSTRACT: Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil carbon although increased stability of crop yields in dry climates is evident. Our analyses suggest pragmatic adoption on larger mechanized farms, and limited uptake of CA by smallholder farmers in developing countries. We propose a rigorous, context-sensitive approach based on Systems Agronomy to analyze and explore sustainable intensification options, including the potential of CA. There is an urgent need to move beyond dogma and prescriptive approaches to provide soil and crop management options for farmers to enable the Sustainable Intensification of agriculture.

Algunas consideraciones en torno a la transdisciplinariedad y a la educación superior

Durante los últimos dos siglos se ha venido sosteniendo la neutralidad y apoliticidad de la ciencia, pero se ha pasado por alto que esta, como construcción humana, no puede ostentar un estatus especial. Es decir, está condicionada históricamente al igual que cualquier otra actividad. La ciencia moderna adquirió su actual división disciplinaria en el siglo XIX, en gran parte por el desarrollo del capitalismo industrial que cubrió el orbe y la conformación de estados-nación y su organización dentro del sistema interestatal, de modo que es una particular forma de entender y estudiar la realidad, pero no la única posible. Las elecciones teóricas y metodológicas hechas desde entonces se han impuesto como la forma natural de aprehender la realidad. La fase actual del proceso de la globalización ha puesto de manifiesto que el marco epistemológico decimonónico –y como parte de él, el nacionalismo metodológico– resulta insuficiente en el presente para explicar ciertos fenómenos sistémicos y ha revelado la necesidad de su superación. En el presente contexto histórico se hace más necesario que nunca superar la dependencia académica y la adopción de una actitud crítica para que la división internacional del trabajo académico y la estructuración de una agenda transnacional para la educación no operen en contra de las zonas y poblaciones pobres del mundo. Ello supone que la universidad defina su papel con respecto a la sociedad desde una dimensión política, antes de que decida y realice su propia reforma. La transdisciplinariedad juega un papel principal en la superación de los viejos modelos de la ciencia y la universidad.

Participation in science and technology : young people's achievement-related choices in late modern societies

Young people’s participation in science, technology, engineering and mathematics (STEM) is a matter of international concern. Studies and careers that require physical sciences and advanced mathematics are most affected by the problem and women in particular are under-represented in many STEM fields. This article views international research about young people’s relationships to, and participation in, STEM subjects and careers through the lens of an expectancy value model of achievement-related choices. In addition it draws on sociological theories of late-modernity and identity, which situate decision-making in a cultural context. The article examines how these frameworks are useful in explaining the decisions of young people – and young women in particular – about participating in STEM and proposes possible strategies for removing barriers to participation.
