Astroparticle physics, a constructive empiricist account
Full text linkAstroparticle physics is an interdisciplinary field embracing astronomy, astrophysics and particle physics. In a recent paper on this topic (2012), Brigitte Falkenburg defended that only scientific realism can make sense of it and that realist beliefs constitute an indispensable methodological principle of research in this discipline. The aim of this work is to show that there exists an anti-realist alternative to this account, along the lines of what Bas van Fraassen showed in his famous book The Scientific Image (1980). Problems and results of astroparticle physics can be understood from an empiricist point of view too, namely that of van Fraassen’s constructive empiricism, which is a more modest and metaphysics-free alternative to scientific realism. Although constructive empiricism can make sense of science no worse than scientific realism does, van Fraassen’s goal is not to demonstrate that his stance is the only viable position, but just that it is not incoherent or proven false by his opponents (see Kusch 2015, 172). In this paper it will be shown that the constructive empiricist stance constitutes a legitimate alternative to scientific realism even when it gets to astroparticle physics and that it does indeed make sense of this new discipline, pace Falkenburg
Is the golden section a key for understanding beauty? Part III
Full text linkOur goal is to prove that the golden section, however important, is not the only key to understand a mathematical-formalizing approach to the idea of beauty. Having developed, from this point of view, reading keys linked to the post-modern, it is necessary to link together the multiple rivulets of knowledge that gather in this direction. Moreover the canons of the approaches presented up to now are very indicative for the understanding of many aspects of beauty, which however depends on the historical moment and the cultures created in the various civilizations. Therefore we can affirm that there is no effective definition of "beauty" that can be codified through fixed canons, but that the concept is expressed by a series of stratifications and interpretations that tend to link several major variations, expressing the various answers given by man to the question: what is the beauty
Why is Bayesian confirmation theory rarely practiced?
Full text linkBayesian confirmation theory is a leading theory to decide the confirmation/refutation of a hypothesis based on probability calculus. While it may be much discussed in philosophy of science, is it actually practiced in terms of hypothesis testing by scientists? Since the assignment of some of the probabilities in the theory is open to debate and the risk of making the wrong decision is unknown, many scientists do not use the theory in hypothesis testing. Instead, they use alternative statistical tests that can measure the risk or the reliability in decision making, circumventing some of the theoretical problems in practice. Therefore, the theory is not very popular in hypothesis testing among scientists at present. However, there are some proponents of Bayesian hypothesis testing, and software packages are made available to accelerate utilization by scientists. Time will tell whether Bayesian confirmation theory can become both a leading theory and a widely practiced method. In addition, this theory can be used to model the (degree of) belief of scientists when testing hypotheses
Forms of Crossed and Simple Polygons
Full text linkIn this paper the author presents a new form of hexagon and the solution of the open problem of classifying plane hexagons. In particular are illustrated the forms of crossed and simple n-gons for n = 3, 4, 5, 6 and also the forms of simple ones for n = 7, 8, 9. A graphic way to construct new forms of polygons is illustrated
The measurement problem in quantum mechanics
Full text linkIn this paper, we discuss the importance of measurement in quantum mechanics and the so-called measurement problem. Any quantum system can be described as a linear combination of eigenstates of an operator representing a physical quantity; this means that the system can be in a superposition of states that corresponds to different eigenvalues, i.e., different physical outcomes, each one incompatible with the others. The measurement process converts a state of superposition (not macroscopically defined) in a well-defined state. We show that, if we describe the measurement by the standard laws of quantum mechanics, the system would preserve its state of superposition even on a macroscopic scale. Since this is not the case, we assume that a measurement does not obey to standard quantum mechanics, but to a new set of laws that form a “quantum measurement theory”
Healing the Psychic Split
Full text linkThis paper is dealing with one of the greatest novels in the British literature, The Golden Notebook by Doris Lessing. The novel and its main character, Anna Wulf can be interpreted in myriad ways, but our analysis is a psychoanalytical one. The introductory part of the paper gives the definitions of the psychoanalytical words that will be later on used in the paper.In The Golden Notebook, the life of Lessing’s main character offers an understanding of issues such as political repression, sexual abuse, single parenthood, writer’s block, and the women’s movement. Anna Wulf’s fragmented personality is caught in the four notebooks that she writes, each one being concerned with one of Anna’s selves. Anna is the most complicated heroine analysed and we will try to discover which of her various selves are confirmed and which are repressed. In Anna’s process of healing, there are two moments of climactic confirmation: the first one when she admits that she is mad and the second one when she admits she has a writer’s block
Phenomenology, Symbolic Interactionism and Research: From Hegel to Dreyfus
Full text linkThe journey of phenomenology apparently is not so extensive, because it was the first half of the twentieth century when Edmund Husserl appeared as the founder of phenomenology. But, it has its very roots in the works of ancient Greek philosophers like Socrates, Plato, and Aristotle. This journey did not stopped here, as various phenomenologists have also been contributing in this field and establishing the linkage between phenomenology and symbolic interactionism as well as its very relation to research. Researchers in the presented work have critically analyzed the contributions of prominent phenomenologists, i.e. from Hegel to Dreyfus and have applied relational analysis. The present study propounds that with the passage of time, the concept of phenomenology has been constructively evolving; in a sense that it has become more calculativ
Bruno Rizzi and Number Theory
Full text linkFranco Eugeni remembers Bruno Rizzi: in this brief introduction, I would like to remember an afternoon spent in “Roma Tre” with Bruno, since we were both Ordinary Professors at that University. We passed it doing a dense program of work for the next three years. At 6.00 pm, I left for “Roseto degli Abruzzi”. At six o'clock a.m. of the next morning, I still have the voice in my ears. A phone call from the Headmaster Ciro d'Aniello, who told me "The Professor is dead" In that afternoon, Emilio Ambrisi and I went to Rome; we were stunned and desperate. Not many days later, a conference was held at the University of Teramo; it was the conference that we had prepared for Bruno, to celebrate his 60th birthday, but it was his memory. In the opening conference, Prof. Antonino Giambo, also fraternal friend of Bruno, burst into a tearful cry, which expressed in a moment, the senses of friendship and love that we all had for the missing friend! Starting from this work with Fabrizio Maturo, the study of some problems left open by the works of Eugeni and Rizzi will be investigated.SuntoRicordo di Franco Eugeni su Bruno Rizzi: in questa brevissima introduzione vorrei ricordare un pomeriggio passato a Roma Tre con Bruno, visto che allora eravamo entrambi Professori Ordinari in quella Università. Lo passammo a fare un denso programma di lavoro per i successivi tre anni. Alle 18.00 ripartii per Roseto degli Abruzzi. Alle sei del mattino successivo, ho ancora la voce nelle orecchie, una telefonata del Preside Ciro d’Aniello, che mi diceva “Il Professore è morto” Nel pomeriggio Emilio Ambrisi ed io ci recammo a Roma, eravamo attoniti e disperati. Non molti giorni dopo si tenne presso l’Università di Teramo un Convegno, era il Convegno che avevamo preparato per Bruno, per festeggiare i suoi 60 anni, fu invece il ricordo. Nella conferenza di apertura il prof. Antonino Giambò, anche lui, come noi, fraterno amico di Bruno, scoppiò in un pianto dirotto, che espresse in un attimo, i sensi dell’amicizia e dell’amore, che tutti noi avevamo per l’amico scomparso! A partire da questo lavoro con Fabrizio Maturo verrà approfondito lo studio di alcune problematiche rimaste aperte dai lavori di Eugeni e Rizzi
Schleiermacher’s Universal Hermeneutics and the Problematics of Rule-Following
Full text linkThis paper investigates how Schleiermacher’s universal hermeneutics can be considered as a better alternative to both, German rationalist aesthetics as pioneered by Christian Wolff, and Kant’s transcendental idealism, to the extent of overcoming the problematics of rule-following. A general account of the necessity of a universal hermeneutics and its meaning from historical practices of exegeses is given. This is then followed by the account of rule-following in the tradition of both German rationalist aesthetics and Kant’s transcendental idealism with latter as expounded in Kant’s Critique of Pure Reason. The investigation is comparative and descriptive. The purpose of this study is to discuss the hermeneutic possibilities in research methodologies for human sciences
Internet and Greek Pontian Associations in Thrace
Full text linkGreeks of Pontian ancestry migrated, forcibly, from Pontus to Greece where they founded Pontian Greek communities, mainly in northern Greece. The rapid increase in usage of the Internet during the past years appears to be significantly affecting the activity of cultural associations in general. The Greek Pontian associations of Thrace have begun taking advantage of the Internet and social networks for their diversified activities, a “modernization” which has not been studied extensively thus far. In this paper, a corresponding analysis is performed, concluding that the activity of the associations on the Internet reflects an upward trend, while an increasing number of them seek to maintain an active presence on the Internet through web sites and social networks. This activity includes primarily press conferences and informative announcements
