It has long been recognized that Dirac's principle might imply that the rate of β decay would vary with the age of the universe. If so, the radioactive ages of meteorites and terrestrial rocks as indicated on the one hand by α decay and on the other by β decay should differ. However, the comparison of these ages is complicated by a large uncertainty in the decay constant for Rb87. Thus the age data must be analyzed to determine the decay constant most compatible with the particular theory of β decay which is used. Using this best decay constant for each theory, we find that the data are more consistent with a β decay rate independent of the age of the universe than with the dependence implied by the Dirac principle.

Muslims today employ various and often conflicting strategies to mitigate contradictions between traditional Islamic teachings and modern science, especially in matters related to the age of the universe and the origin of humans. On the one hand, any scientific theory deemed problematic might be rejected outright; on the other, Islamic texts may be reinterpreted to fully support a novel scientific theory. There is, however, an alternative hermeneutical approach that uses intra-textual analysis to acknowledge “interpretative latitude” in the Qurʾān and other Islamic texts – the possibility that these texts allow for ambiguity and multiple interpretations that may or may not agree with modern science. In this paper, human evolution will serve as a case study of the implementation of this approach via a structured discussion of common Muslim objections to the theory. The paper will conclude with a discussion of the implications of this approach on defining the role of the Qurʾān and on the boundaries of religion and science.

According to Aristotle all heavenly movement is ultimately due to the activity of forty-seven (or fifty-five) ‘unmoved movers'. This doctrine is highly remarkable in itself and has exercised an enormous historical influence. It forms part of a world-picture the outlines of which are as follows. The universe consists of concentric spheres, revolving in circles. The outermost of these bears the fixed stars. The other either bear planets or, insofar as they do not, contribute indirectly to the movements of the latter. Each sphere is moved by the one immediately surrounding it, but also possesses a movement of its own, due to its mover, an unmoved, incorporeal being. (It was these beings which the schoolmen designated as theintelligentiae separatae.) The seemingly irregular movements of the planets are thus viewed as resulting from the combination of regular circular revolutions. The earth does not move and occupies the centre of the universe. Such was Aristotle's astronomic system, essential parts of which were almost universally adopted by the Arabic, Jewish, and Christian philosophers of the Middle Ages.

В статье обсуждается вопрос о двух противоположных функциях черной дыры. С одной стороны она является творцом для галактики, а с другой - разрушителем барионной материи. Предполагается, что эти функции заложены самой эволюцией Вселенной. Деструкция материи до фотонов в ЧД считается наиболее вероятным событием. The question of two opposite functions of a black hole is discussed. On the one hand, it is the creator for the galaxy, and on the other-the destroyer of baryonic matter. It is assumed that these functions were laid down by the evolution of the Universe itself. The destruction of matter to photons in BH is considered the most likely event.

An individual or whole we understand to be whatever is represented in any given discourse by signs belonging to the lowest logical type of which that discourse makes use. What is conceived as an individual and what as a class is thus relative to the discourse within which the conception occurs. One task of applied logic is to determine which entities are to be construed as individuals and which as classes when the purpose is the development of a comprehensive systematic discourse.The concept of an individual and that of a class may be regarded as different devices for distinguishing one segment of the total universe from all that remains. In both cases, the differentiated segment is potentially divisible, and may even be physically discontinuous. The difference in the concepts lies in this: that to conceive a segment as a whole or individual offers no suggestion as to what these subdivisions, if any, must be, whereas to conceive a segment as a class imposes a definite scheme of subdivision—into subclasses and members.The relations of segments of the universe are treated in traditional logistic at two places, first in its theorems concerning the identity and diversity of individuals, and second in its calculus of membership and class-inclusion. But further relations of segments and of classes frequently demand consideration. For example, what is the relation of the class of windows to the class of buildings? No member of either class is a member of the other, nor are any of the segments isolated by the one concept identical with segments isolated by the other. Yet the classes themselves have a very definite relation in that each window is a part of some building. We cannot express this fact in the language of a logistic which lacks a part-whole relation between individuals unless, by making use of some special physical theory, we raise the logical type of each window and each building to the level of a class—say a class of atoms—such that any class of atoms that is a window will be included (class-inclusion) in some class that is a building. Such an unfortunate dependence of logical formulation upon the discovery and adoption of a special physical theory, or even upon the presumption that such a suitable theory could in every case be discovered in the course of time, indicates serious deficiencies in the ordinary logistic. Furthermore, a raising of type like that illustrated above is often precluded in a constructional system by other considerations governing the choice of primitive ideas.

Orthodox eschatology is based, on the one hand, on the affirmation of the clear distinction between the uncreated nature of God and the created nature of His creatures, and, on the other hand, on the possibility of their union through divine Grace. Towards this eschatological union creation is called ontologically, through the divine reasons based on Reason-Christ, Who draws to Himself man and the universe, because He is at the same time Cause and Target, Alpha and Omega. The Church is working and preparing for the Feast of the Great Union, which will take place at the Second Coming of the Lord

Por otra parte, las supuestas profecí­as mayas acerca de un evento astronómico el próximo 21 de diciembre de 2012, en realidad no son acordes a la cosmovisión maya prehispánica, coinciden sin embargo con temores milenaristas propios del pensamiento occidental que se agudizan en una época de crisis global.   Palabras Clave: Mayas, religión, astronomí­a, profecí­as del 2012.   Abstract Mayan  thought  in  respect  to  astronomy  and  the  calendar  have  a  great originality and correspond to a way of understanding a complete different reality to the one of the western thought. Mayan people conceive that time is subject to cycle recurrences (day-night, solar year, and periods of 52 years), each one supposes destruction and renovation of cosmos. On the other hand, the supposed Mayan prophecies about an astronomical event next December 21st  2012, do not in fact agree with the view of the world of the pre Hispanic Mayans, however they coincide with millennial fear proper of the western thought that worsen in this times of global crisis.   Key words: Mayans, religion, astronomy, 2012 prophecies.

Sometimes we take ourselves to be saying some-thing about what really is possible (even if not actual), what is not possible, what is inevitable, what would or would not happen were certain conditions to obtain; we take ourselves to be saying something about how matters stand modally. When this is our aim, what features of the universe are responsible for the truth or falsity of what we say? I shall offer reasons for thinking that an ontology of interrelated powers or dispositionalities provides the resources requisite for an accounting of real modalities, truth makers for important modal truths. Consideration of these reasons will, in addition, disclose surprising connections between dispositionality, on the one hand, and, on the other hand, causation and causal laws as these are commonly understood in philosophy.

Recent advances in physics render a reconsideration of the Place of Mathematics in the Interpretation of the Universe particularly timely. On the one hand, we have the introduction of non-euclidian geometry, which has given rise to much controversy informed or otherwise; on the other hand, we find mysterious forms of mathematics, invented to cope with the quantum difficulties, which so far have escaped metaphysical investigation or criticism. It would seem most desirable that these modes of interpreting reality should be examined from the broader philosophical point of view.

In this paper, I will try to propose a general characterisation of the spirit in Hegel'sEncyclopaedia. This characterisation is based on the opposition between nature and spirit. More precisely, in my view the Hegelian spirit can be defined as the activity of bringing the natural exteriority back to a living totality.We know that for Hegel the notion of spirit takes so many shapes that their unity is difficult to find. For instance, what does the soul in the subjective spirit, property in the objective spirit and the cult of the Greek gods in the absolute spirit have in common? Furthermore, when we consider property, for example, the problem is knowing if the spirit is here constituted by the owner, by the deeds of ownership or by the living relationship between the owner and the possessed goods.Moreover, the Hegelian spirit is a philosophical descendant of several different traditions. The question is, therefore, to know how these traditions are linked in the Hegelian notion. I will present these briefly before stating my general hypothesis about the definition of the spirit.First, the Hegelian spirit is connected to thenoûsof the Greek philosophers (the Latinspiritus, intellectus). Thenoûs— on the one hand, an immaterial entity leading the universe, and, on the other, a faculty of the soul — is most often distinguished by its separate and rational nature. For Hegel too, the spirit, as a non-perceptible entity, constitutes the freest and most rational stage in the development of the Idea.

The poet and writer Sohrab Sipehri (1928-1980) played a particular role in the formation and development of Iranian poetry at the beginning of the twentieth century. This poet created his style of expression and was an enlightened person who provided a holistic connection of modern philosophical views with orthodox ideas. He was a philosopher-poet, an artistic thinker who was able to give the contemporary content of the interpretation of theories of «Unity» - («wahdat al-wujud») and «Perfect man» - («komil inson») in the traditional system of mystical views. As a great writer he created a new set of poetic emblems and symbols in his approach, he had a special place in modern Persian poetry as a poet who contributed to the development of the literary movement “new poetry” (“sher-i now”) of Iranian poetry. The main goal of the article is to study the role and place of Sohrab Sipehri in the development of the literary process, philosophical and educational beliefs, and mystical ideas expressed in his works. As a result, the essence and content of artistic symbols, strong heritage, artistic thinking of poet were revealed. The poet advocates the creation of harmony between man and the universe. S. Sipehri, on the one hand, tries to show clearly the boundaries and limitations between man and the universe. And on the other hand, he argues that these boundaries should be removed between them. When S. Sipehri thinks about existence and what belongs to him, he speaks in a language that is typical of the Surrealist style, that is, difcult to understand, but the philosophical meaning of such a statement stems from the mystical views of Eastern mysticism. The poet›s artistic thinking connects and harmonizes the imagination of the East and the West.
