Astronomy on Trial systematically and convincingly argues against every aspect of the theory behind the idea of the "Big Bang." Using a readable style that incorporates the laws of physics, Roy C. Martin exposes the impossibilities that have been so commonly manipulated to support the Big Bang theory. He carefully explains the absurdities that have come to represent modern day cosmology and high-energy physics that have arisen from the group-think phenomenon. Martin reveals this group-think as the tendency of scientists to (...) fit the astronomical observational data that flow into context within the standard theories already established by the community of cosmologists. The author's witty, point-by-point exposition of the impossibility of the Big Bang not only provides insights into this one situation, but reveals a troubling trend of a lack of skepticism in scientific research in general that calls for a reevaluation of conclusions in all other fields of science.

Around 1716, the French astronomer and academician Joseph-Nicolas Delisle took up a new project: the twinned topics of Chinese chronology and astronomy. Unable to access Chinese sources and not knowing any fellow savants who shared this particular interest, Delisle methodically made extracts and compiled data from the existing European literature. Among Delisle's papers at the Observatoire de Paris still exist the results of this research, including a list of the books he found relevant. This paper develops a close reading of (...) Delisle's notes from this period to stage his journey into a recondite arena of technical and textual analysis, and to examine the scholarly practices and generic conventions through which early modern European savants confronted the Chinese astronomical tradition.

This chapter begins with a discussion of Egyptian and Babylonian influences in Greek astronomy. It considers the development of Pythagorean astronomy before Philolaus. It then focuses on the difficulty of identifying an individual contribution to astronomy by Pythagoras or specific early Pythagoreans. It shows that Alexander relied on Aristotle, who connected with Philolaus neither the harmony of the spheres nor the geocentric model on which it is based. The surviving works of Aristotle actually contain no indication that he associated the (...) harmony of the spheres with Philolaus' system. (shrink)

Relying on an analysis of the case of gravitational lensing, Hacking argues for a "modest antirealism" in astronomy. It is shown here that neither his scientific arguments nor his philosophical doctrines imply an antirealist conclusion. An alternative, realistic interpretation of gravitational lensing, and of the nature and history of astronomy more generally, is suggested.

Heracleides Ponticus, a pupil of the schools of Plato and Aristotle, who lived from about 390 to 310 B.C., shared the wide interests of many of his pre-Platonic predecessors. Diogenes Laertius gives a long list of his works, many of them now known only by their titles, which he divided into writings on ethics, physics, grammar, music, rhetoric, and history. Like most of his predecessors he gave some attention to the heavens and speculated about the nature of the moon , (...) comets , the infinity of the cosmos ; he was best known in antiquity, in this field, for his suggestion that the phenomena could be saved if the heavens were at rest and the earth revolved about the central axis .2 One of two pieces of evidence for his involvement in anything more than this general, inexact speculation in the field of astronomy is contained in the commentary on Plato's Timaeus written in Latin by Chalcidius somewhere at the beginning of the fourth century A.D.; it is this passage which this paper will discuss.

This volume represents the first which interfaces with astronomy as the fulcrum of the sciences. It gives full expression to the human passion for the skies. Advancing human civilization has unfolded and matured this passion into the comprehensive science of astronomy. Advancing science’s quest for the first principles of existence meets the ontopoietic generative logos of life, the focal point of the New Enlightenment. It presents numerous perspectives illustrating how the interplay between human beings and the celestial realm has informed (...) civilizational trends. Scholars and philosophers debate in physics and biology, the findings of which are opening a more inclusive, wider picture of the universe. The different models of the universal order and of life here presented, all aiming at the first principles of existence—accord with the phenomenology/ontopoiesis of life within the logos-prompted primogenital stream of becoming and action, which points to a future of progressing culture.

This source book provides new information about a much neglected aspect of the scientific tradition of the Islamic Middle Ages, focusing on folk astronomy and its relations to religious duties ).

This book provides the first presentation of the bilingual textual material that illustrates the transmission of Islamic astronomy to scientists of the Indian Sanskritic tradition. It includes editions of the chapter of the _Tadhkira_ in which the mid-thirteenth century Persian astronomer, Nasīr al-dīn al-ṭūsī discussed the new solutions that he devised to overcome certain technical problems in the lunar and planetary models of Ptolemaic astronomy and of the learned commentary composed by al-Birjandī in the early sixteenth century together with the (...) Sanskrit translation of both made by Nayanasukha at Jaipur in 1729. An English translation of the Arabic texts and a commentary discussing their technical meanings and the deviations from them in the Sanskrit version together with a glossary of the Arabic and Sanskrit technical vocabulary conclude the volume.

Abraham ibn Ezra d'Espagne (m. 1167) fut l'un des plus importants savants ayant contribué à la transmission de la science arabe à l'Occident. Ses ouvrages en astrologie et en astronomie, rédigés en hébreu puis traduits en latin, étaient considéréd comme faisant autorité par de nombreux savants juifs et Chrétiens. Parmi les ouvrages qu'il a traduits de l'arabe en hébreu, certains sont perdus dans leur langue originale et ses propres ouvrages renferment certaines informations concernant des sources anciennes mal ou pas (...) du tout connues par ailleurs. Ibn Ezra semble être le premier a avoir consigne l'une des sept méthodes pour dresser les maisons astrologiques. Cette méthode avait par la suite été utilisée par Lévi ben Gershom (m. 1344) dans le Midi de la France. (shrink)

L’importance de l’astronomie dans l’œuvre d’Auguste Comte est à la mesure de la place fondatrice qu’il lui accorde dans sa propre classification des sciences que constitue le Cours de philosophie positive. Comte dispense même un cours populaire d’astronomie, dont l’objectif n’est pas de former à l’astronomie mais à la « saine philosophie » positive. D’où le regard philosophique qu’il porte sur elle comme l’indique son Traité philosophique d’astronomie populaire. Pour Comte, l’astronomie est donc tout à (...) la fois, un modèle de science positive et un faire-valoir de la philosophie positive et même de l’engagement positiviste, quitte à restreindre assez fortement son champ d’étude.

In Hellenistic Astronomy: The Science in Its Contexts, renowned scholars address questions about what the ancient science of the heavens was and the numerous contexts in which it was pursued.

In this paper I contest Ian Hacking’s claim that astronomers do not experiment. Riding on this thesis is a re-evaluation of his view that astronomers are less justified than other natural scientists in believing in the existence of the objects they study, and that astronomers are not proper natural scientists at all. The defense of my position depends upon carefully examining what, exactly, is being manipulated in an experiment, and the role of experimental effects for Hacking’s experimental realism. I argue (...) that Hacking’s experimental realism is not adequately defended, and even if we accept it in good grace, the case can be still made that astronomers experiment by Hacking’s account.

Plato's comments on astronomy and the education of the guardians at Republic 528e ff have been hotly disputed, and have provoked much criticism from those who have interpreted them as a rejection or denigration of observational astronomy. Here I argue that the key to interpreting these comments lies in the relationship between the conception of enquiry that is implicit in the epistemological allegories, and the programme for the education of the guardians that Plato subsequently proposes. We have, I suggest, been (...) too eager to stress the similarities here, when recognition of the differences may supply us with the tools required for a better understanding of 528e ff, one that to a large extent disarms the anti-empirical critique. My discussion proceeds in three stages. Firstly, Plato takes great care to place his comments on astronomy in the context of the preceding epistemological allegories. Is there any evidence here, where Plato might be thought to discuss enquiry in general, that he rejected or denigrated observation? I argue that even if Plato advocated a 'Two Worlds' (TW) ontology, he still envisaged a dynamic process of enquiry, interrelating sensibles and intelligibles, the investigation of each being necessary but not sufficient to achieve the overall aim. Secondly, Plato appears to be deriving how we ought to go about educating the guardians from how we ought to conduct our enquiries. While the two are intimately related there are important differences, recognition of which turns the supposed rejection of observation into an affirmation of the need for an initial empirical approach. I contend that this makes good sense of the internal structure of 528e ff, and of its relations to other parts of the Republic. Thirdly, I discuss the Republic in relation to the evidence offered by later works on the question of astronomy and observation, and raise the question of whether Plato's views on the imperfection of the sensible world necessarily lead to the denigration of careful and prolonged empirical work.

We as Classical scholars need to (re)learn what most of our nineteenth and early twentieth century colleagues used to know about e. g. the phases of the moon. If we do not we may totally miss essential points of some texts, or fail to understand the nature of problems pointed out by former generations, as in the case of the Homeric Hymn to Hermes. We also ought to go further than our predecessors: knowing some basic facts about the heavenly bodies, (...) e. g. about the visibility of the planet Venus, can make us see some Greek poems in a (to us, at least) new light.

This richly illustrated book discusses the ways in which astronomy expanded after 1945 from a modest discipline to a robust and modern science. It begins with an introduction to the state of astronomy in 1945 before recounting how in the following years, initial observations were made in hitherto unexplored ranges of wavelengths, such as X-radiation, infrared radiation and radio waves. These led to the serendipitous discovery of more than a dozen new phenomena, including quasars and neutron stars, that each triggered (...) a new area of research. The book goes on to discuss how after 1985, the further, systematic exploration of the earlier discoveries led to long-term planning and the construction of new, large telescopes on Earth and in Space. Key scientific highlights described in the text are the detection of exoplanets, the unexpected discovery of the accelerated expansion of the Universe, a generally accepted model for the large-scale properties of the Universe and the ΛCDM theory that explains how the galaxies and stars of the present Universe were formed from minute irregularities in the homogenous gas that filled the early Universe. All these major scientific achievements came at a price, namely the need to introduce two new phenomena that are as yet unexplained by physics: inflation and dark energy. Probably the deepest unsolved question has to be: Why did all of this start with a Big Bang? (shrink)

The most discussed and mysterious column within the Babylonian astronomy is columnΦ. It is closely connected to the lunar velocity and to the duration of the Saros. This paper presents new ideas for the development and interpretation of columnΦ. It combines the excellent Goal-Year method with old ideas and practices from the “schematic astronomy”. Inspired by the old “TU11” rule for prediction of times of lunar eclipses, it proposes that columnΦ, in a similar way, used the sum of the Lunar (...) Four to predict times of lunar eclipses as well as the duration of one, 6, and 12 months by means of what usually is called “R–S” schemes. It also explains fully the structure and development of such schemes, a fact that strongly supports the new interpretation of columnΦ. (shrink)

James Forbes' critical examination of the probabilistic reasoning, which led John Michell to infer a physical connection between optically double and multiple stars, is analysed. It is argued that despite the interpretations of its nineteenth-century defenders, Michell's reasoning has some force which does not depend upon questionable Bayesian principles. Attention is drawn to some of the ambiguities concerning the notion of randomness, and it is shown that these ambiguities render Forbes' objections less than conclusive.

In one of the most disputed passages of Greek literature Plato in the Republic, 7. 528e–530c prescribes astronomy as the fourth study in the education of the Guardians. But what sort of astronomy? According to one school of thought it is a purely speculative study of bodies in motion having no relation to the celestial objects that we see. While this interpretation has rejoiced the hearts of Plato's detractors, who regard him as an obstacle to the progress of science, it (...) has dismayed his admirers. Another school of thought holds that what Plato meant was that astronomers must get to know the real motions of the heavenly bodies as opposed to their apparent motions as seen by us on earth. The opposed interpretations may be set out in the following representative citations from Sir Thomas Heath and John Burnet. (shrink)

In a somewhat polemical article on ‘Solstices, Equinoxes, and the Presocratics’ D. R. Dicks has recently challenged the usual view that the Presocratics in general, and the Milesians in particular, made significant contributions to the development of scientific astronomy in Greece. According to Dicks, mathematical astronomy begins with the work of Meton and Euctemon about 430 B.C. What passes for astronomy in the earlier period ‘was still in the pre-scientific stage’ of ‘rough-and-ready observations, unsystematically recorded and imperfectly understood, of practical (...) men’ whose chief concern was to fix the seasons for ploughing, seed-time, sailing voyages and religious festivals. Ionian speculation, says Dicks, took very little note of such observation: ‘some of its wilder flights of fancy might have been avoided, if it had taken more’. In this account of the rise of Greek astronomy, the natural philosophers have no part to play. Their theories represent a speculative enterprise without a scientific future, a philosophic sideline with no impact on the development of observational science from Hesiod to Meton or the development of mathematical astronomy from Meton to Ptolemy.I believe that such a dichotomy between early philosophy and early science in Greece is misguided in principle, and that it seriously distorts our picture of the initial phases of each discipline. It also imposes a considerable strain upon our credulity. Take the case of Anaxagoras who, according to Plato and Theophrastus, had given a causal explanation of eclipses of the moon a generation before Meton. (shrink)

In the domain of astronomy the object oriented paradigm of informatics needs to construct an ontology to be able to reason about concepts and to construct queries in a computerized knowledge system. The article presents approaches to ontology in philosophy, the natural sciences and informatics and shows their limits and reciprocity.

A characteristic hallmark of medieval astronomy is the replacement of Ptolemy’s linear precession with so-called models of trepidation, which were deemed necessary to account for divergences between parameters and data transmitted by Ptolemy and those found by later astronomers. Trepidation is commonly thought to have dominated European astronomy from the twelfth century to the Copernican Revolution, meeting its demise only in the last quarter of the sixteenth century thanks to the observational work of Tycho Brahe. The present article seeks to (...) challenge this picture by surveying the extent to which Latin astronomers of the late Middle Ages expressed criticisms of trepidation models or rejected their validity in favour of linear precession. It argues that a readiness to abandon trepidation was more widespread prior to Brahe than hitherto realized and that it frequently came as the result of empirical considerations. This critical attitude towards trepidation reached an early culmination point with the work of Agostino Ricci, who demonstrated the theory’s redundancy with a penetrating analysis of the role of observational error in Ptolemy’s Almagest.

At some time around 200 A.D., the Stoic philosopher and teacher Cleomedes delivered a set of lectures on elementary astronomy as part of a complete introduction to Stoicism for his students. The result was _The Heavens, _the only work by a professional Stoic teacher to survive intact from the first two centuries A.D., and a rare example of the interaction between science and philosophy in late antiquity. This volume contains a clear and idiomatic English translation—the first ever—of _The Heavens, _along (...) with an informative introduction, detailed notes, and technical diagrams. This important work will now be accessible to specialists in both ancient philosophy and science and to readers interested in the history of astronomy and cosmology but with no knowledge of ancient Greek.

While scholars and policy practitioners often advocate for science and technology transfer as a motor for economic growth, many in Latin America have long warned of the pitfalls of such top-down, North-South transfers. To many in Latin America, scientific aid or cooperation from the North has often reproduced hierarchies that perpetuate dependency. Large astronomy observatories located in Chile – with a high price tag, cutting-edge technology, and seen to answer seemingly arcane research questions – seem ripe for reproducing precisely these (...) kinds of hierarchical relationships. Using data from documents, interviews, and a site visit to Gemini South, one of several large telescopes in Chile, this paper takes a historical perspective to examine how resilient these hierarchical relationships are. Over forty years, astronomy in Chile grew thanks to new policies that fostered cooperation among universities and gave locals privileged access to the telescopes. But the community also grew in ways that reproduced dependency: foreign science benefits significantly, the Chilean state operates in top-down ways, and its support for science leaves it blind to the benefits high-tech telescopes deliver to Chile, which are not linked to export-led growth. The state appears as both an obstacle and an enabler to the growth of a national scientific community. (shrink)

This work inaugurates a critical inquiry into whether the ideas of Karl Popper, a philosopher of science, are used by astronomers and astrophysicists, a practicing community of scientists. It examines four basic components of Karl Popper's philosophy— falsification, prohibition, simplicity, and risk taking— and the extent that these themes become integrated into recent scientific literature on astronomy, astrophysics, cosmology, and stellar evolutionary theory. It concludes that the philosophy of science is highly relevant to the practice of astronomy, and that Karl (...) Popper plays a unique role in directing different communities of astronomers and cosmologists. (shrink)
