This authoritative biography addresses the life and work of the quantum physicist David Bohm. Although quantum physics is considered the soundest physical theory, its strange and paradoxical features have challenged - and continue to challenge - even the brightest thinkers. David Bohm dedicated his entire life to enhancing our understanding of quantum mysteries, in particular quantum nonlocality. His work took place at the height of the cultural/political upheaval in the 1950's, which led him to become the most notable American scientist (...) to seek exile in the last century. The story of his life is as fascinating as his ideas on the quantum world are appealing. (shrink)

A pesquisa em informação quântica sugere uma íntima conexão entre o conceito de informação e a teoria quântica, mas essa conexão envolve nuances cuja análise é o objeto deste trabalho. A sabedoria comum nesse campo divide-se em duas grandes áreas, não excludentes entre si. Há os que são movidos pela possibilidade de uso da teoria quântica em um novo campo, o da computação, independentemente do esclarecimento de seus fundamentos, aqui incluído o conceito de "informação". Alguns consideram que estamos diante de (...) um grande problema conceitual sem resposta satisfatória no momento, enquanto que outros, dentre os que reconhecem a magnitude do problema, têm proposto formulações com a pretensão de solução do problema. Este artigo tem pretensões modestas. Não pretendemos aportar novas soluções ao problema, nem apoiar uma das soluções existentes. Temos a expectativa de através da análise histórico-conceitual do problema mapear as diversas possibilidades, apontando o que nos parecem ser aspectos fortes e fracos nessas possibilidades. Research in quantum information suggests a close connection between information and quantum theory. The aim of this article is to analyze nuances involved in this connection. Scientists in this field are divided into two overlapping camps. Some are motivated only by the use of quantum features to improve information processing, in spite of concerns about the foundations of the quantum theory, while others recognize deep conceptual problems of this theory, and attempt to solve them. This article has modest ambitions. It aims only to chart, by way of historical and conceptual analysis, the diverse possibilities available, indicating the strengths and weaknesses of each of them.

Este ensaio introdutório faz uma breve apresentação do tratado de óptica atribuído a Euclides de Alexandria, inserindo-o no contexto das teorias sobre a visão formuladas pelas doutrinas filosóficas antigas. Ressalta-se o antagonismo entre a análise geométrica da visão, empreendida por Euclides, e as considerações filosóficas acerca dos processos físicos subjacentes à sensação visual. Pretende-se mostrar que o objeto da óptica euclidiana é a percepção visual daquilo que Aristóteles denomina "sensível comum". This introductory essay provides an abridged presentation of the optical (...) treatise attributed to Euclid of Alexandria, placing it in the context of theories about vision formulated by the ancient philosophical doctrines. I emphasize the antagonism between the geometric analysis of vision, undertaken by Euclid, and the philosophical considerations about the physical processes underlying visual sensation. In addition, I aim to show that the object of Euclidean optics is the visual perception of what Aristotle calls "common sensible". (shrink)

This book tells the fascinating story of the people and events behind the turbulent changes in attitudes to quantum theory in the second half of the 20th century. The huge success of quantum mechanics as a predictive theory has been accompanied, from the very beginning, by doubts and controversy about its foundations and interpretation. This book looks in detail at how research on foundations evolved after WWII, when it was revived, until the mid 1990s, when most of this research merged (...) into the technological promise of quantum information. It is the story of the quantum dissidents, the scientists who brought this subject from the margins of physics into its mainstream. It is also a history of concepts, experiments, and techniques, and of the relationships between physics and the world at large, touching on themes such as the Cold War, McCarthyism, Zhdanovism, and the unrest of the late 1960s.

Neste artigo, analisamos os desafios historiográficos relacionados à produção de biografias no âmbito da História da Ciência. Em especial, discutimos as ideias apresentadas pelo historiador francês Jacques Le Goff em seu livro São Luís, publicado em 1996. Essa análise, de natureza teórica e metodológica, é cotejada com o esboço panorâmico da biografia do físico norte-americano David Bohm, recentemente publicada sob o título David Bohm – A Life Dedicated to Understanding the Quantum World. O tema tem relevância também para a história (...) da ciência no Brasil, uma vez que nosso personagem lecionou na Universidade de São Paulo entre fins de 1951 e início de 1955. (shrink)

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political (...) philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain insight into the utility of cross-disciplinary scholarship. This anthology will appeal to researchers, students, and teachers in philosophy of science, social science, and liberal education programmes. 1. Introduction Section I.

O NEOCONSTITUCIONALISMO E A CONCRETIZAÇÃO DA DIGNIDADE DA PESSOA IDOSA.

This paper offers a contribution to debates around integrative aspects of systems biology and engages with issues related to the circumstances under which physicists look at biological problems. We use oral history as one of the methodological tools to gather the empirical material, conducting interviews with physicists working in systems biology. The interviews were conducted at several institutions in Brazil, Germany, Israel and the U.S. Biological research has been increasingly dependent on computational methods, high-throughput technologies, and multidisciplinary skills. Quantitative scientists (...) are joining biological departments and collaborations between physicists and biologists are particularly vigorous. This state of affairs raises a number of questions, such as: What are the circumstances under which physicists approach biological problems in systems biology? What kind of interdisciplinary challenges must be tackled? The paper suggests that, concerning physicists’ move to work on biological systems, there are common reasons to move, the transition must be understood in terms of degrees, physicists have a rationale for simplifying systems, and distinct conceptions of model and modeling strategies are recurrent. We identified problems regarding linguistic clarity and integration of epistemological aims. We conclude that cultural unconformities within the systems biology community have important consequences to the flow of scientific knowledge. (shrink)

The rising interest, in the late 20th century, in the foundations of quantum physics, a subject in which Franco Selleri has excelled, has suggested the fair question: how did it become so? The current answer says that experiments have allowed to bring into the laboratories some previous gedanken experiments, beginning with those about EPR and related to Bell’s inequalities. I want to explore an alternative view, by which there would have been, before Bell’s inequalities experimental tests, a change in the (...) views shared by physicists concerning the intellectual status of that issue. I will take three cases which will serve as the threads of our story: the connections between Bohm’s causal interpretation and Bell’s inequalities; Wigner’s ideas on the measurement problem; and finally Everett’s relative states formulation. In the end, I will discuss how those threads were gathered together by creating foundations of quantum physics as a field of research. (shrink)

A (IN)COMPATIBILIDADE ENTRE O TRIBUNAL DO JÚRI BRASILEIRO E O SISTEMA INTERAMERICANO DE PROTEÇÃO DOS DIREITOS HUMANOS: UMA ANÁLISE À LUZ DA PRESUNÇÃO DE INOCÊNCIA.

Este trabalho analisa idéias e atividades de Karl Popper referentes à controvérsia sobre interpretações e fundamentos da mecânica quântica. Atenção especial será dedicada às relações entre Popper e o físico italiano Franco Selleri, ao longo da década de 1980. A interpretação proposta por Popper para os enunciados probabilísticos como propensões, bem como seu ponto de vista realista, contribuíram para estabelecer uma ponte entre suas investigações filosóficas e a pesquisa física em mecânica quântica, ainda que sua idéia sobre as propensões tenha (...) tido uma pequena repercussão entre físicos, matemáticos e filósofos. Argumentaremos neste trabalho que a influência de Popper na física foi possível devido à legitimação, a partir de 1970, da controvérsia sobre os fundamentos da teoria quântica como uma genuína controvérsia científica com implicações filosóficas. Popper foi beneficiado por essa legitimação, mas ele também contribuiu para fazer aquela controvérsia chegar a um público mais amplo que aquele dos físicos envolvidos na própria controvérsia.I intend to present in this paper Karl Popper’s ideas and activities concerning the controversy about the interpretations and foundations of quantum mechanics. I will pay special attention to Popper’s relationship with the Italian physicist Franco Selleri, during the 1980s. Popper’s ideas of propensity and realism contributed to build a bridge between his philosophy and physical research in quantum mechanics, even if his idea of propensity has had a weak reception among physicists, mathematicians and philosophers. I will argue that Popper’s contributions to physics were possible due to the legitimization in the 1970s of the controversy about the foundations of quantum mechanics, a process which permitted a trading zone between physics and philosophy. Popper was benefited by that process, but he also contributed to give to that controversy a larger audience thanthat of the physicists involved in that controversy. (shrink)

Crucial to most research in physics, as well as leading to the development of inventions such as the transistor and the laser, quantum mechanics approaches its centenary with an impressive record. However, the field has also long been the subject of ongoing debates about the foundations and interpretation of the theory, referred to as the quantum controversy. This Oxford Handbook offers a historical overview of the contrasts which have been at the heart of quantum physics for the last 100 years. (...) Drawing on the wide-ranging expertise of several contributors working across physics, history, and philosophy, the handbook outlines the main theories and interpretations of quantum physics. It goes on to tackle the key controversies surrounding the field, touching on issues such as determinism, realism, locality, classicality, information, measurements, mathematical foundations, and the links between quantum theory and gravity. This engaging introduction is an essential guide for all those interested in the history of scientific controversies and history of quantum physics. It also provides a fascinating examination of the potential of quantum physics to influence new discoveries and advances in fields such quantum information and computing. (shrink)

Emotional intelligence is a psychological skill that aids athletes in the control of emotions and optimization of sports performance. The present study investigated the psychometric properties of the Self-Report Emotional Intelligence Test in 508 Brazilian youth and adult athletes. Data analysis was conducted through Exploratory and Confirmatory Factor Analysis, Cronbach’s alpha, composite reliability and Pearson’s Correlation. EFA revealed the one-factor model with 26 items with the best adjustment. CFA confirmed the one-factor model with 26 items with best greater fit. No (...) evidence of invariance was found, suggesting that the SSEIT must be used with caution when comparing gender and age groups. The external validity was found in the correlation of EI and cognitive anxiety and self-confidence. It is concluded that the Brazilian version of SSEIT for the sports context presented acceptable psychometric properties, however, showed limitations that should be explored in the future. (shrink)

In 1966 the Brazilian physicist Klaus Tausk (b. 1927) circulated a preprint from the International Centre for Theoretical Physics in Trieste, Italy, criticizing Adriana Daneri, Angelo Loinger, and Giovanni Maria Prosperi`s theory of 1962 on the measurement problem in quantum mechanics. A heated controversy ensued between two opposing camps within the orthodox interpretation of quantum theory, represented by Leon Rosenfeld and Eugene P. Wigner. The controversy went well beyond the strictly scientific issues, however, reflecting philosophical and political commitments within the (...) context of the Cold War, the relationship between science in developed and Third World countries, the importance of social skills, and personal idiosyncrasies.

Guilt and shame are self-conscious emotions with implications for mental health, social and occupational functioning, and the effectiveness of sports practice. To date, the assessment and role of athlete-specific guilt and shame has been under-researched. Reporting data from 174 junior elite cricketers, the present study utilized exploratory factor analysis in validating the Athletic Perceptions of Performance Scale, assessing three distinct and statistically reliable factors: athletic shame-proneness, guilt-proneness, and no-concern. Conditional process analysis indicated that APPS shame-proneness mediated the relationship between (...) general and athlete-specific distress. While APPS domains of guilt-proneness and no-concern were not significant mediators, they exhibited correlations in the expected direction with indices of psychological distress and well-being. The APPS may assist coaches and support staff identify players who may benefit from targeted interventions to reduce the likelihood of experiencing shame-prone states. (shrink)

This paper reviews the hole argument as an argument against spacetime substantivalism. After a careful presentation of the argument itself, I critically review possible responses.

What is morality? How many moral values are there? And what are they? According to the theory of morality-as-cooperation, morality is a collection of biological and cultural solutions to the problems of cooperation recurrent in human social life. This theory predicts that there will be as many different types of morality as there are different types of cooperation. Previous research, drawing on evolutionary game theory, has identified at least seven different types of cooperation, and used them to explain seven different (...) types of morality: family values, group loyalty, reciprocity, heroism, deference, fairness and property rights. Here we explore the conjecture that these simple moral ‘elements’ combine to form a much larger number of more complex moral ‘molecules’, and that as such morality is a combinatorial system. For each combination of two elements, we hypothesise a candidate moral molecule, and successfully locate an example of it in the professional and popular literature. These molecules include: fraternity, blood revenge, family pride, filial piety, gavelkind, primogeniture, friendship, patriotism, tribute, diplomacy, common ownership, honour, confession, turn taking, restitution, modesty, mercy, munificence, arbitration, mendicancy, and queuing. These findings indicate that morality – like many other physical, biological, psychological and cultural systems – is indeed a combinatorial system. Thus morality-as-cooperation provides a principled and powerful theory, that explains why there are many moral values, and successfully predicts what they will be; and it generates a systematic framework that has the potential to explain all moral ideas, possible and actual. Pursuing the many implications of this theory will help to place the study of morality on a more secure scientific footing. (shrink)

Despite its importance in the history of philosophy, the work of the Spanish thinker Averro"es (1126-1198) has been left largely unexplored in this century. This book is the only general account of Averro"es' philosophy in English. Leaman analyzes his thought and influence, particularly his metaphysics and theory of meaning, arguing that while his work belongs within the cultural and political context of medieval Islam, it remains of considerable philosophical and historical significance.

Por incorporar a esperança na pedagogia crítica para, um só tempo, humanizar radicalmente a educação e transformar a sociedade, ele faz aumentar nossas expectativas sobre o que são capazes de fazer uma teoria e uma pedagogia ao construir um caminho que demonstra a indissociabilidade de ordem teórica e prática.
