Extractions: A fundamental aspect of a change in paradigm is that there must be an alternative possibility. If no such possibility exists then there will be no change in paradigm. If Tycho had thought unequivocally that comets must be sub-lunar, then he would not have formulated his new theory. The supernova of 1572 provided him with the possibility of the new theory. When that star appeared in the sky the Aristotelian conception of the heavens as unchanging became obsolete. Armed with this idea, Tycho was then able to propose that comets, then considered transient objects, belonged in the super-lunar sphere of activity.7 Descartes, however, explained the path of comets with his vortex theory. In this conceptualization, both comets and planets were formed from dead stars, with comets being the more dense of the two. The less dense planets acquired momentum equal to that of the vortex they were in, but comets, because of their greater density, achieved a greater velocity and escaped the vortex in which they were formed. They then wandered from vortex to vortex, with each path being slightly curved.14 Descartes, in contrast to Kepler, did not base his theory on any mystical conceptions of order or purpose, but rather maintained a mechanical explanation of cometary movement.
Extractions: Shakespeare: Hamlet Astronomy is the oldest science. Observing the stars and planets has always been important e.g. for time determination or for calendar making. We find great interest in astronomical questions in ancient cultures as well as in more recent centuries. history of astronomy one could present the topics in an even more interesting and motivating way for a broader range of pupils. I think this should start in the beginning years of the 'Gymnasium'. Furthermore, with interdisciplinary teaching one could combine science with cultural history. Here I give a concrete example of a subject which lends itself to such an interdisciplinary approach - sundials. After an introduction dealing with antiquity and the Middle Ages, I shall present three sundial examples drawn essentially from the Early Modern period (roughly 15th-17th centuries). I think it is useful to supplement book-learning with practical work - i.e. making such instruments and learning to use them. This can be rounded out by a visit to a museum to see original instruments or by a walk through town to find sundials.
LIBRARIES In Vienna, Bessarion had the opportunity to meet with important men of letters,such as georg peurbach, Niccolaus da Cusa and the young Regiomontanus, http://www.libraries.gr/nonmembers/en/libraries_markiani.htm
Extractions: The Marcian library in Venice was based on the personal collection of manuscripts and printed books owned by the great Renaissance man of letters and leading representative of Byzantine scholarship, Cardinal Bessarion. When Bessarion became aware that the end of his life was approaching, he decided to donate his invaluable collection to the Venetian Republic, with the sole purpose of its serving as a symbol of the cultural heritage of western civilisation and a beacon of Hellenism. Cardinal Bessarion, whose secular name was Basil, was born in Trebizond on 2 January 1403 and received his initial education under Ignatios Chortasmenos, the metropolitan of Selymbria. He studied rhetoric in Constantinople at a time when the Italian humanists were frequent visitors to the Byzantine capital to study Greek and acquire Greek manuscripts. Within this circle, he studied alongside Francesco Filelfo, Giovanni Aurispa and many others, who later became outstanding figures of the Renaissance. He embraced monasticism at an early age, and was ordained monk in the order of St Basil (30 January 1423), taking the name Bessarion; he became a

Source(s) of Funding: Hang Seng Bank Golden Jubilee Education Fund for Research Start Date: March 1998 Abstract: It is commonly accepted that the language deficiencies existing in Chinese magazines and newspapers have an adverse effect on the language proficiency of the general public. The first year students of the Department of Chinese, The University of Hong Kong, should in general have a good command in the Chinese language. This research targets on how and in what way, if any, the media has affected them with the aim to identify any remedies that may be required. Results obtained from this project could be beneficial to both our students and the paper media. With proper analysis, teaching approaches and methods could be more precisely designed.

One of the major publications of Renaissance natural philosophy, the Epitome of Ptolemy's Almagest appears; the authors, Georg Peurbach (1423-1461) and Johannes Regiomontanus (1436-1476), symbolize a shift from reverence for Ptolemy and antiquity to respect coupled with confident innovation.

Extractions: Gary Boyle , the Observers Group Chair, opened the last meeting of the Ottawa Centre of the 1900s with the comment, "Well, folks, they lost another one!" He was referring, of course, to the sad loss of NASAs Mars Polar Lander probe . During the time of the meeting, hope was still alive that contact would eventually be made, but alas, twas not to be. Moving on to exciting news, Gary also spoke of how astronomers gathered more evidence of extra-solar planets by measuring a 1.7% drop in a stars light as a suspected planet moved in front of it relative to Earth. It seems that the Galaxy is indeed teeming with planets. What a fitting end to the 1900s! Paul Comision was our usual first speaker of the month to present his latest Cutting Edge of Astronomy topic. Paul discussed the "bottom-up" theories about how galaxies are formed through collisions and mergers of smaller galaxies (much like how pile-ups are formed on Ottawa highways during freezing rain), as opposed to the older "top-down" theories where a galaxy is born a specific size and stays that way throughout its life, and how the bottom-up theories were gaining prominence. The December 1999 issue of Astronomy magazine covered this topic in detail.

Extractions: 'We who have seen the whole earth, either as represented on maps and globes or as reproduced in satellite photographs, find it difficult to adopt the perspective of those who have not. The image of a floating blue and green sphere, with sharply defined oceans and continents, has been so thoroughly assimilated into our mind's eye as to become intuitive. However, the great majority of mankind has lived and died without ever glimpsing this image, and even today, many isolated races remain innocent of it. For such peoples, mind must take the place of maps in giving shape and structure to the inhabited earth; where empirical data give out they employ any other means available - theory, myth, and fantasy - to define and depict the space in which they dwell. [James S. Romme, The edges of the Earth in ancient thought , Princeton, 1992, p. 9] This concise summary of the ways in which people deal with images of the world could well serve as the basis of a manifesto of what - as seen from my own perspective - have been the goals of the Coronelli Society: to study, to unravel and to elucidate the diversity of images that people have formed of the world around them throughout the ages. All images of the world have been and still are being created within a specific scientific and social context. Before they can be understood these contexts have to be studied in terms of contemporary ideas and values. This in particular holds for models of the world such as globes and armillary spheres, which have been made since antiquity by a manifold of makers: scientists and artists, women and monks, teachers and school children.

Extractions: This paper treats the history of a surveying problem in which both the height of a mountain or tower and its distance from the observer are to be determined in cases where the distance between observer and object cannot be crossed. This problem arises in works by the Chinese (Liu Hui), Indians (Aryabhata, Brahmagupta), Arabs (al-Biruni) and the Christians of the Middle Ages ( Geometria incerti auctoris , Hugo de Sancto Victore), all of which present similar examples and methods of solution. Jens Høyrup: Seleucid Innovations in the Babylonian;"Algebraic" Tradition and their Kin Abroad Seleucid and Demotic mathematical sources, along with problems and techniques that continue older Babylonian and Egyptian traditions, both present us with a number of innovations: the treatment of "quasi-algebraic" problems about rectangular sides, diagonals and areas, and summations of series "until 10." This paper characterises these two problem types and investigates their presence in certain Neopythagorean and agrimensorial Greco-Roman writings, and in Mahavira’s compendium of Jaina mathematics, and discusses their possible influence on the Chinese Nine Chapters on Arithmetic We investigate the historical roots and branches of a number of common approximations of some irrational quantities arising in ancient and medieval mathematics. Almost all of these values or methods were known from China to Western Europe, but in our investigations of their origins and diffusion we have taken into account the varying contexts in which they appear. The historical record of their diffusion seems to suggest, in at least one case, a single origin and diffusion from that center, but, in other cases, multiple origins and again diffusion from these.
