The questions that were purely in the realms of philosophy are now beginning to be answered by science. The second Venice Conference on Cosmology and Philosophy explores the anthropic principle which states that the Universe has the conditions we observe because we are here. Out of all possible universes we can only experience the restricted class that permits observers. This realization has profound implications for cosmology, philosophy and theology; all of which are explored in this book by thirteen contributors who (...) gathered to discuss and share their theories within the context of science. The result is a unique collection of papers of great value to professional astronomers and philosophers interested in the role of observers in the Universe. (shrink)

Following with the discovery of the electron by J. J. Thomson at the end of the nineteenth century a steady elucidation of the structure of the atom occurred over the next 40 years culminating in the discovery of nuclear fission in 1938–1939. The significant steps after the electron discovery were: discovery of the nuclear atom by Rutherford (Philos Mag 6th Ser 21:669–688, 1911 ), the transformation of elements by Rutherford (Philos Mag 37:578–587, 1919 ), discovery of artificial radioactivity by (...) class='Hi'>Joliot-Curie and Joliot-Curie (Comptes Rendus Acad Sci Paris 198:254–256, 1934 ), and the discovery of the neutron by Chadwick (Nature 129:312, 1932a , Proc R Soc Ser A 136:692–708, 1932b ; Proc R Soc Lond Ser A 136:744–748, 1932c ). The neutron furnished scientists with a particle able to penetrate atomic nuclei without expenditure of large amounts of energy. From 1934 until 1938–1939 investigations of the reaction between a neutron and uranium were carried out by E. Fermi in Rome, O. Hahn, L. Meitner and F. Strassmann in Berlin and I. Curie and P. Savitch in Paris. Results were interpreted as the formation of transuranic elements. After sorting out complex radio-chemistry and radio-physics O. Hahn and F. Strassmann came to the conclusion, beyond their belief, that the uranium nucleus split into smaller fragments, that is nuclear fission. This was soon followed in 1939 by its theoretical interpretation by L. Mietner and O. Frisch. (shrink)

Marie Curie, double Prix Nobel de physique et de chimie, est sans aucun doute la femme scientifique la plus connue au monde. Sa fille aînée, Irène Joliot-Curie a suivi brillamment sa trace, obtenant elle aussi un Prix Nobel de chimie. Elle a par ailleurs donné son nom à un prix qui récompense aujourd’hui le parcours remarquable de femmes scientifiques. Mais derrière la carrière exceptionnelle de ces deux femmes, derrière les découvertes scientifiques d’intérêt mondial, il y a une (...) mère et une... (shrink)

Note by editors of Voprosy filosofii: The great transformer of modern natural science, Albert Einstein, was not only a physicist of genius, not merely the discoverer of outstanding scientific discoveries: he was also a remarkable human being, a courageous protagonist of peace and justice on earth. A convinced humanist and antifascist, he spoke out irreconcilably against chauvinism, militarism, and misanthropy, always and everywhere. Defending the principles of humanism and high ideals of citizenship, aware of his responsibility as a scientist, he (...) protested passionately against the use of atomic and hydrogen weapons. Along with Bertrand Russell, Frederic Joliot-Curie, and other major scientists, Einstein signed the widely known manifesto that played an important role in founding the Pugwash movement of scientists.

The ArgumentEinstein's mass-energy relationship was not confirmed experimentally until 1933 when Bainbridge showed that the Cockcroft-Walton experiment afforded a test of it. Earlier, however, it had been used constantly in the analysis of nuclear reactions, as can be seen in those involved in the determination of the mass of the neutron. Chadwick in 1932 was convinced that the neutron mass was about 1.0067 amu (atomic mass units), indicating that the neutron was a proton-electron compound, since that figure was less than (...) the sum of the proton and electron masses. Chadwick's value was challenged in 1933 by Lawrence, who proposed a much lower value of 1.0006 amu, and by Curie and Joliot, who proposed a much higher value of 1.011 amu.Much controversy ensued; eventually, Chadwick and Goldhaber showed in 1934 that the neutron mass was about 1.0080 amu, greater than the sum of the proton and electron masses, proving that the neutron was a new elementary particle (which could decay spontaneously), and providing conclusive experimental support for excluding electrons from the nucleus. These results remained unchanged with further refinements in the last decimal place, the entire pursuit of which provided still further vindication of Einstein's massenergy relationship. (shrink)

We investigate whether ordinary quantification over objects is an extensional phenomenon, or rather creates non-extensional contexts; each claim having been propounded by prominent philosophers. It turns out that the question only makes sense relative to a background theory of syntax and semantics (here called a grammar) that goes well beyond the inductive definition of formulas and the recursive definition of satisfaction. Two schemas for building quantificational grammars are developed, one that invariably constructs extensional grammars (in which quantification, in particular, thus (...) behaves extensionally) and another that only generates non-extensional grammars (and in which quantification is responsible for the failure of extensionality). We then ask whether there are reasons to favor one of these grammar schemas over the other, and examine an argument according to which the proper formalization of deictic utterances requires adoption of non-extensional grammars.

Are we witnessing progress or regress in the recent increasing popularity and electoral success of populist politicians and parties in consolidated democratic nations? ... Is the innovative use of popular referendum in Great Britain to settle fundamental constitutional questions a progressive or regressive innovation? ... Similarly, is the increasing use of constituent assemblies to change constitutions across the world evidence of progress in democratic constitutionalism, or, a worryingly regressive change back toward unmediated popular majoritarianism? ... This paper reflects on some (...) of the perils and promise of framing such questions with the conceptual couplet of progress and regress. It considers four compelling critiques of the use of ‘progress’ and its cognates in sociopolitical theory, as well as arguing that such concepts are nevertheless ineliminable for our normative theories. The paper concludes by suggesting that we can avoid the most serious problems by employing only conceptions of political progress and regress that are piecemeal, pragmatic, and processual. (shrink)

In recent years, there has been a heated debate about how to interpret findings that seem to show that humans rapidly and automatically calculate the visual perspectives of others. In the current study, we investigated the question of whether automatic interference effects found in the dot-perspective task (Samson, Apperly, Braithwaite, Andrews, & Bodley Scott, 2010) are the product of domain-specific perspective-taking processes or of domain-general “submentalizing” processes (Heyes, 2014). Previous attempts to address this question have done so by implementing inanimate (...) controls, such as arrows, as stimuli. The rationale for this is that submentalizing processes that respond to directionality should be engaged by such stimuli, whereas domain-specific perspective-taking mechanisms, if they exist, should not. These previous attempts have been limited, however, by the implied intentionality of the stimuli they have used (e.g. arrows), which may have invited participants to imbue them with perspectival agency. Drawing inspiration from “novel entity” paradigms from infant gaze-following research, we designed a version of the dot-perspective task that allowed us to precisely control whether a central stimulus was viewed as animate or inanimate. Across four experiments, we found no evidence that automatic “perspective-taking” effects in the dot-perspective task are modulated by beliefs about the animacy of the central stimulus. Our results also suggest that these effects may be due to the task-switching elements of the dot-perspective paradigm, rather than automatic directional orienting. Together, these results indicate that neither the perspective-taking nor the standard submentalizing interpretations of the dot-perspective task are fully correct. (shrink)

Autobiography and Teacher Development in China investigates the roles of autobiography in teacher education, as several scholars in China recontextualize Western conceptions of teacher development, combining them with uniquely Chinese cultural conceptions to articulate a reconceptualization of teacher development that holds worldwide significance. Framed by the work of Zhang Hua and William F. Pinar, these theoretical and practical essays point to an internationally inflected reconceptualization of teachers' professional development, pre-service and in-service. This volume addresses multiple movements of teacher education reform (...) worldwide, focused on crafting a nationally distinctive course not only internationally, but also culturally, historically, and locally.

Theorists of public reason such as John Rawls often idealize constitutional courts as exemplars of public reason. This paper raises questions about the seduction and limits of analogies between theorists’ account of public reason and actual constitutional jurisprudence. Examining the work product of the United States Supreme Court, the paper argues that while it does engage in reason-giving to support its decisions—as the public reason strategy suggests— those reasons are (largely) legalistic and specifically juristic reasons—not the theorists’ idealized moral-political reasons (...) on matters of fundamental principle. But if constitutional courts do not engage on matters of fundamental principle, then a public reason strategy for assuaging democratic worries about judicial review would no longer be open: prominent liberal and deliberative democratic theorists could no longer point to the alleged superiority of constitutional courts to speak in the name of, and for, the people’s shared political principles. The paper extends beyond the U.S. case study by pointing to three institutional factors explaining the disanalogy between what some constitutional courts do and what public reason theories require them to do. It concludes with considerations about whether the public reason strategy might be more successfully applied to international courts. (shrink)

There are two popular views regarding the origin of critical thinking: (1) The concept of critical thinking began with Socrates and his Socratic method of questioning. (2) The term ‘critical thinking’ was first introduced by John Dewey in 1910 in his book How We Think. This paper argues that both claims are incorrect. Firstly, critical reflection was a distinguishing characteristic of the Presocratic philosophers, setting them apart from earlier traditions. Therefore, they should be recognized as even earlier pioneers of critical (...) thinking. Secondly, John Dewey not only used the term ‘critical thinking’ before 1910, but there were also other authors who used it before him. The meaning of ‘critical thinking’ at the turn of the twentieth century was shaped by various traditions of linguistic usage, including literary criticism, science and medicine, and Kantian philosophy.

The Implementation Problem for conceptual engineering is, roughly, the problem conceptual engineers face when attempting to bring about the conceptual change they support. An important aspect of this problem concerns the extent to which attempting to implement concepts can lead to unintended negative consequences. Not only can conceptual engineers fail to implement their proposals, but their interventions can produce outcomes directly counter to their goals. It is therefore important to think carefully about the prospect of attempted implementation leading to unintended (...) negative consequences: what sort of negative consequences can conceptual engineers expect? Are some forms of conceptual engineering more likely than others to lead to such consequences? And is conceptual engineering still viable even given the risk of such consequences? This paper addresses such questions. I begin by outlining different forms of conceptual engineering (Section 1), before examining how they can produce unintended negative consequences (Section 2). I then discuss some implications of the fact that attempted implementation can produce unintended negative consequences, suggesting that, among other things, some forms of conceptual engineering are less viable than others (Section 3). I conclude, though, by considering some of the ways in which conceptual engineering is nonetheless a worthwhile pursuit (Section 4). (shrink)

From climate change to fossil fuel dependency, from the uneven effects of natural disasters to the loss of biodiversity: complex socio-environmental problems indicate the urgency for cross-disciplinary research into the ways in which the social, the natural and the technological are ever more entangled. This ground breaking text moves between environmental sociology and environmental geography, political and social ecology and critical design studies to provide a definitive mapping of the state of environmental social theory in the age of the anthropocene. (...) Environments, Natures and Social Theory provokes dialogue and confrontation between critical political economists, actor network theorists, neo-Malthusians and environmental justice advocates. It maps out the new environmental politics of hybridity moving from hybrid neo-liberals to end times ecologists, from post environmentalists to cyborg eco-socialists. White, Rudy and Gareau insist on the necessity of a critical but optimistic hybrid politics, arguing that a more just, egalitarian, democratic and sustainable anthropocene is within our grasp. This will only be brought into being, however, by reclaiming, celebrating and channeling the reconstructive potential of entangled hybrid humans as inventive hominids, creative gardeners, critical publics and political agents. Written in an accessible style, Environments, Natures and Social Theory is an essential resource for undergraduate and postgraduate students across the social sciences. (shrink)

This work describes the concept of bond order. It shows that covalent bond energy is correlated to bond order. Simple expressions which included bond order are introduced to calculate bond energies of homo-nuclear and hetero-nuclear bonds. Calculated values of bond energies are compared with literature values and show there is very good agreement between and calculated and experimental values in the vast majority of cases. Bond order reveals the strength of a bond and shows the number of bonds in both (...) homo-nuclear and hetero-nuclear covalent bonds. (shrink)

This is a book about the philosophy of Henri Bergson which shows how relevant Bergson is to much contemporary philosophy. The book takes as its point of departure Bergson's insistence on precision in philosophy. It then discusses a variety of topics including laughter, the nature of time as experienced, how intelligence and language should be construed as a pragmatic product of evolution, and the antinomies of reason represented by magic and religion. This is not just another exposition of Bergson's work. (...) It offers an account of why Bergson commanded such a massive reading public in his own day and why he deserves to be read now. Written in a terse and clear style, this book will prove appealing to teachers and students of philosophy, cognitive science, psychology, religious studies and literature. (shrink)

Disjunctivism about perceptual appearances, as I conceive of it, is a theory which seeks to preserve a na.

Robinson argues that by certain threshold criteria, pregnant women qualify for a higher moral status by reason of their pregnancies. While her intention is to make this a status upgrade for women, we worry that it may result in a status downgrade for women as a class, by presupposing and reinforcing women’s value in relation to their reproductive labour. Historically, central to feminist analysis is resistance to reductive accounts of women in relation to their reproductivity. For example, de Beauvoir addressed (...) men’s transcendence and contrasted it with women’s immanence, a status distinction possible because women are mired in expectations that they will marry, produce children and remain in the domestic realm; and for her part, Firestone argued that biological reproduction underlies women’s inferiority to men and that ‘The reproduction of the species by one sex for the benefit of both (should) be replaced by…artificial reproduction’1 2 Her concern was to liberate women from expectations of biological reproduction so their productive value in society is not reduced to their reproductive contributions. A formidable body of analysis in this same vein cautions against collapsing the value of women into their pregnancies, so much so that some commentators even distinguish ‘mothering’ from gestation.3 Robinson’s argument that pregnant women qualify at a higher threshold of personhood emphasises ….

Physical and biological measurements might display range values extending towards infinite. The occurrence of infinity in equations, such as the black hole singularities, is a troublesome issue that causes many theories to break down when assessing extreme events. Different methods, such as re-normalization, have been proposed to avoid detrimental infinity. Here a novel technique is proposed, based on geometrical considerations and the Alexander Horned sphere, that permits to undermine infinity in physical and biophysical equations. In this unconventional approach, a continuous (...) monodimensional line becomes an assembly of countless bidimensional lines that superimpose in quantifiable knots and bifurcations. In other words, we may state that Achilles leaves the straight line and overtakes the turtle. (shrink)

Bredo C. Johnsen: Observation: What Quine calls observation sentences lie at the heart of his reflections on observation and its roles in prompting our theorizing, providing evidence for our theories, and serving as the test of those theories' truth. The first four sections of this chapter – “Observation sentences,” “The two types of observation sentence,” “Introspection,” and “Roles of experience” – are devoted to expounding and clarifying his fundamental conception of these sentences, showing that he recognized both objective and subjective (...) observation sentences, that correlatively he gives introspection an important place in our cognitive lives, and, in particular, that he assigns our introspective knowledge of our sensory experiences three important roles in his epistemology. Since about 1970, Quine's conception of what constitutes our evidence about the nature of empirical reality has been radically misunderstood by almost all his readers, with disastrous consequences for the understanding of his entire epistemology; a final section – “Stimulations as evidence” – is therefore devoted to remedying this situation.
