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.

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.

There are reasons to believe that most of the stars of the catalogue were observed by Hipparchus, between the years 160 BC to 130 BC. In the later Middle Ages and in the Renaissance the Almagest had a tremendous impact on European astronomy. Copernicus, Tycho Brahe and Kepler made an extensive use of this book. Almost an exact copy of the Star Catalogue was included by Copernicus in his De Revolutionibus.

Girolamo Bigazzini giovandosi allo scopo tra le altre delle opere di georg peurbach e Giovanni http://www.dipmat.unipg.it/~bartocci/BIGAZ.html
Extractions: UN MATEMATICO PERUGINO DEL '5OO: GIROLAMO BIGAZZINI di Umberto Bartocci ed Emanuela Ughi Ricorreva qualche anno fa il quinto centenario della nascita di una singolare figura di scienziato rinascimentale, quel Girolamo Bigazzini che fu ai suoi tempi detto "Prencipe de' Mathematici" e "lume di tutta l'Italia nelle speculative Scientie Mathematiche". Anche se sulle date della vita del Bigazzini i testi non sono del tutto concordi(1), appare senz'altro certo che questi ebbe i suoi natali nella citta' di Perugia, sicche' e' parsa cosa opportuna ad alcuni cultori della storia delle matematiche operanti nella Universita' degli Studi di Perugia il ricordarlo con questo scritto. Si e' gia' citato un entusiastico giudizio di Raffaele Sozii (1529-1589), che del Bigazzini fu allievo e biografo (cfr. [4] e [5] ), sulle qualita' scientifiche e sulla notorieta' del nostro personaggio, nonostante che, come osserva anche l'Ermini nella sua monumentale opera dedicata alla storia di questo Ateneo (cfr. [3] , p. 586), si possa sospettare che dietro tali lusinghiere considerazioni si nasconda una certa dose di esagerazione, dovuta probabilmente all'affetto del discepolo per il maestro(2). Pure, della grande fama che il Bigazzini seppe procurarsi si puo' essere assolutamente certi, poiche' in termini altrettanto elogiativi si espressero anche altri suoi contemporanei, quali ad esempio il Pellini ( [14] , p. 983) ed il Crispolti ( [9] , p. 359). Interessatosi cosi' sempre di piu' il Bigazzini agli studi matematici, divenne rapidamente tanto perito in campo scientifico da svolgere successivamente egli stesso funzioni di maestro nell'ambiente perugino. A causa di cio' fu chiamato, sin dalla sua giovinezza, il "Vecchietto", poiche' per l'appunto(7) mostro' "senno canuto in fanciullesca etade", cosi' come riporta il Crispolti ( [9] , p. 359).

Twain's fictional Yankee predicting an eclipse to save himself from being burned at the stake may sound silly in the late 20 th century, but eclipses have a long history as omens or portents of evil. Even Christopher Columbus predicted a lunar eclipse on Feb 29, 1504 to get the inhabitants of Jamaica to cooperate with him during one of his visits to the New World. The islanders refused to supply him and his sailors with food, so Columbus recalled an upcoming lunar eclipse and told the natives he would make the moon change color and lose its light. The eclipse astonished the natives. Food and support was forthcoming. Columbus was even raised to a rank of a god.

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

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.
