Cosmology can mean many different things to different people. Sandage (1970) once described it as “the search for two numbers” (Ho and qo). At the other end of the spectrum, it may comprise almost all the interesting bits of astronomy and physics that bear on how the universe got to be the way it is. Supernovae can probe many of these bits because they are bright, have been going on for a long time, and contribute directly to the chemical and, perhaps, dynamical evolution of structure in the universe.

One of the most impressive features of Anna Karenina is the way in which Tolstoy draws the reader's imagination beyond the literal level of the narrative into generalizations that seem mythical in a manner difficult to articulate. With Dostoevsky or Melville, one sees immediately a propensity for exploiting the symbolic value of things. With Tolstoy, things try, as it were, to resist conversion: they strive to maintain their “thingness” as empirical entities. A character in Dostoevsky is usually only half man; the other half is Christ or Satan. Moby Dick is obviously only half whale; the other half is Evil or some principle of Nature. But Anna Karenina is emphatically Anna Karenina. Like almost all of Tolstoy's characters, she has a proficiency in the husbandry of identity; she jealously hoards her own unique reality, so that it becomes difficult to say of her that she is a “type” of nineteenth-century Russian lady or a “symbol” of modern woman or an “archetypical” Eve or Lilith.

The conquest of a dominant place over the members of the same race, with the result of using the power such a place allows and having the acceptance of the other members for being the leaders is a characteristic of the adult relationship between almost all animal species. The former time of childhood was dedicated to the imitation of the adults and to the experimenting of behaviors, or, in other words, learning and playing. Humberto Maturama believes that humans are, in behavioral tenns, an exception, as the time of childhood is extended throughout most adult life, which defines us humans as a neotenic race, and with the use of other behaviors, we have transformed what is the usual master/slave relation of adult members from other races. Like this, the family in the way we live it, becomes a human-invented structure that implies relationships between its members which are bounded by mutual trust and love. Mutatis mutandis we spend our life repeating relationships that use the same pattern. In this way, love would be the main engine of evolution and also our greatest invention.

In the analysis of Anaxagoras’ physics in view of the relation between his teachings on multitude and heterogeneity, two central questions emerge: 1) How can the structure of the universe considered purely mereo-topologically help us explain that at the first cosmic stage no qualitative difference is manifest in spite of the fact that the entire qualitative heterogeneity is supposedly already present there? 2) How can heterogeneity become manifest at the second stage, resulting from the noûs intervention, if according to fragment B 6 such a possibility requires the existence of “the smallest”, while according to the general principle stated in fragment B 3 there is not “the smallest” but always only “a smaller”? This paper showcases the perplexity of these two questions but deals only with the former. The answer follows from Anaxagoras’ being a thoroughgoing infinitist in the way in which no Greek physicist was: the principle of space isotropy operative in geometry is extended to physics as well. So any two parts of the original mixture are similar to each other not only in view of the smaller-larger relation but also because each contains everything that the other one contains. This in effect means that at the stage of maximal possible heterogeneity each part of any part contains infinitely many heterogeneous parts of any kind whatsoever. So, neither can there be homogeneous parts in view of any qualitative property, nor can there be predominance in quantity of parts of any kind that would make some property manifest.

Human progress depends on the discovery of the forces which are active in the universe and of the way to use them so as to accomplish desired ends. Power is in itself non-moral, and may be used for either moral or immoral purposes. All experience proves that conservatism is an immense power in human nature, and in religion probably more than in any other sphere of human life. It seems strange, then, that more attention has not been given to the nature and source of this power, and to the methods by which it may be so employed as to help and build up rather than obstruct and destroy the spiritual life of men.The power of conservatism affects doctrine, ethics, ceremonial and liturgical forms, and polity in unequal degrees, although it affects them all very greatly. This essay, however, is concerned only with conservatism in doctrine, and leaves the other fields to other students.

There is a similarity in the critical treatment that has been accorded to the Antigone and to Measure for Measure. The parallelisms help to illustrate the way in which errors of emphasis in one direction lead to compensatory distortions in another; and the plays themselves, widely though they differ in many ways, cast some light the one on the other.Both plays have a heroine more obviously than they have a hero. Antigone gives Sophocles' play its name, and Shakespeare's is commonly; thought of as primarily the story of Isabella, though the title lays stress on the abstract theme rather than on any of the characters, and though we may if we choose remember that the source-play was called Promos and Cassandra (i.e. Angelo and Isabella). Both heroines, moreover, more clearly ‘stand for’ specific moral values than is usual in drama— which, as R. W. Chambers has pointed out for Isabella, is not to say; that they are allegorical. The difficulty comes when we ask how far each play is the story of the heroine, and both have been adversely criticized because of unguarded answers to this question. It was perhaps easier with Measure for Measure. It was a ‘problem play’, and Shakespeare could not be expected to write a well-constructed comedy while he was ‘in the depths’ and ought to have realized that he was in his Tragic Period. In dealing with, but it has been thought that he took an unconscionably long time to learn that a play should be one and not two, and that the Ajax and the Antigone (and probably the Trachiniae) are specimens of what he did before he learnt it.

Abstract In Quantum Mechanics, two particles are entangled if their physical states depend on one another's so that if we find one of them in state A, for example, we will be sure that the other is in state B. However, until the state of a quantum particle is measured, it will be in a superposition of states, being in neither one nor the other until then, so when an entangled particle is measured, its pair also assumes a state instantly and regardless of how far away it is from the other particle at that time. As promising as it could be to use this fact for instantaneous communication, Quantum Mechanics seems to claim this is impossible, as no method ever invented to do this has worked until today. What we demonstrate here theoretically is that with a protocol and simple optical devices, two people who share polarized entangled pairs of photons can send information to each other faster than light. If this model of communication proves to be experimentally functional, we will have a contradiction to Einstein's theories of relativity, and otherwise, we will have Quantum Mechanics predicting something that does not happen in real life. This result, therefore, shows there is something fundamental about the universe we do not know yet. One of these theories must be mistaken and both deal with fundamental aspects of reality, such as the dynamics of space and time, and the particles that almost all matter around us are made of. Besides, this result is of great relevance also because it has immediate applications in several areas if the model works experimentally, as in space exploration and security, since it will allow the creation of non-interceptable instantaneous communication technologies.

Abstract This article investigates a book-archeological approach to early modern Bible reading that maps the complex interactions between the substantive elements of a book (text, paratext, illustrations) on the one hand, and its historical readers and the traces they left on the other. That method is applied to all 43 extant copies of the Dutch Vorsterman Bible of 1533–1534. The editions printed by Willem Vorsterman were for a long time regarded as Protestant. However, the Bibles had the approval of the secular and ecclesiastic authorities and were intended for a Catholic public. The edition of 1533–1534 is a glossed Bible with many historicizing, chronological, linguistic and typological paratextual elements. The former owners of the 43 Bibles and their confessional background are examined. Intended and unintended traces of use give clues to the actual use of the Bible. The article turns at the end to a heavily annotated copy, examining the religious ideas of the annotator and the way in which he used the Bible.

Plato's so-called ‘middle period’ saw the composition of what are generally agreed to be his finest philosophical dramas, and of these the Symposium is usually singled out for special praise. Yet it is only recently that serious attempts have been made to approach the Symposium as a work of literature rather than a philosophical treatise. Those who employ the work as a source-book for Platonist doctrines rarely venture beyond Socrates' dialectical refutation of Agathon and his report of what Diotima told him (199c-212b); and if they do, it is to point out the logical or perceptual fallacies — i.e. the philosophical deficiencies — of the other five encomia and to find in Alcibiades' contribution a glowing tribute by Plato to that most remarkable of human personalities, the philosopher Socrates. This, however, is not the way to arrive at a real understanding of the Symposium. The author clearly intends the reader to respond to this work not as a philosophical treatise on the subject of Eros but as a work of literature which portrays a group of thinking human beings engaged in appraisal of an issue which is of fundamental importance in their lives. His primary purpose in dramatising this intellectual event is thus not to expound the philosopher's conception of Eros or to expose our minds to auto to kalon (‘the beautiful itself’). Rather the true subject of the work is man the intellectual animal, whose logoi (‘speeches’) demonstrate his capacity for analysing, evaluating and idealising his feelings and aspirations. It depicts ‘philosophy brought down from the sky and located in the cities and homes of men’; we are shown how, and how successfully, philosophy can function as a vital constituent of human life, rather than a barren and essentially irrelevant dispute about the mechanics of the universe.

Abstract In a famous passage drawing implications from determinism, Laplace introduced the image an intelligence who knew the positions and momenta of all of the particles of which the universe is composed, and asserted that in a deterministic universe such an intelligence would be able to predict everything that happens over its entire history. It is not, however, difficult to establish the physical possibility of a counterpredictive device, i.e., a device designed to act counter to any revealed prediction of its behavior. What would happen if a Laplacean intelligence were put into communication with such a device and forced to reveal its prediction of what the device would do on some occasion? On the one hand, it seems that the Laplacean Intelligence should be able to predict the device's behavior. On the other hand, it seems like that device should be able to act counter to the prediction. An examination of the puzzle leads to clarification of what determinism does (and does not) entail, with some insights about various other things along the way.

O presente texto apresenta uma reflexão sobre papéis de gênero transmitidos na publicidade direcionada ao público infantil. O material analisado foi o encarte publicitário de uma rede de lojas divulgado por ocasião do dia das crianças, em 2014. O estudo buscou perceber a maneira como são retratadas as imagens das meninas e dos meninos no referido material. A análise do material evidenciou uma forma polarizada ao retratar as crianças. A avaliação do material permitiu perceber uma associação dos meninos ao universo da aventura através de mercadorias com apelo aos super-heróis e as meninas ao universo da beleza materializado a partir de produtos ligados às princesas. Foi possível perceber que o encarte veiculou modelos estereotipados de feminilidade e de masculinidade. PALAVRAS-CHAVE: Representações de Gênero; Publicidade; Dia das Crianças. RESUMENEste artículo presenta una reflexión sobre los roles de género transmitidos en la publicidad dirigida a los niños.

The material that was analyzed was an ad of a store chain, published in occasion of the kids’ day, in 2014. The study aimed to notice the way in which the images of boys and girls are shown in this material. The analysis of this material showed a polarized way to refer to kids. The evaluation of that ad made it possible to realize that there is a link between the boys and the universe of the adventure, by commodities with an appeal for super heroes, and, on the other hand, a link between the girls and the universe of beauty, materialized by products that had to do with princesses. It was possible to notice that the ad transmitted stereotyped models of femininity and masculinity. PALABRAS CLAVE: Gender representations; Publicity; Kids Day.
