Osserva Mira! Di John E. Isles Tratto da febbraio 1996 Edizione italiana a cura di Mario Farina La rivista indispensabile di astronomia omicron Ceti (11K gif) UN MERAVIGLIOSO MISTERO E' possibile che quella di Fabricius non fu la prima osservazione riportata di Mira. Appena un anno prima, il 28 novembre 1592, astronomi coreani e cinesi notarono una stella "particolare" nella Balena che rimase visibile per 15 mesi (ma presumibilmente non per tutto questo periodo). Questo avrebbe permesso l'osservazione dei massimi di Mira per tre o quattro cicli prima della scoperta di Fabricius. Uranometria General Catalogue of Variable Stars. Johannes Hewelcke (meglio conosciuto con il nome latinizzato di Hevelius) inizia le osservazioni regolari di Mira nel 1648 e nel 1662 pubblica uno studio intitolato Historiola Mirae Stellae, Durante il massimo, nello spettro di Mira si rileva la presenza di diverse linee in emissione dell'idrogeno.

Essay on Correctly Interpreting Descartes' La Géométrie Jason B. Hill Undergraduate of Pure Mathematics The University of Michigan-Flint Uppsala University After having researched different philosophical, mathematical, and historical aspects of René Descartes, I have been convinced that the vastness of misunderstanding and differences in interpretations of La Géométrie can be explained by explicating the grounds on which it was written, and the means in which it has been read. It is without question that the work is not understood in the context in which it was intended to be, and that any proper understanding of the work is possible only when considering Descartes’ reasons for publishing it where and when he did. I aim to show that this is the case in a method such that both mathematicians and philosophers can follow with ease, after only being familiar with key aspects of Descartes’ Discourse on the Method of Reasoning Well and Seeking Truth in the Sciences Discourse on Method, or Discourse Descartes published the Discourse on Method in 1637. In original form, it was published in French. This fact alone is curious, since learned writings of the time were traditionally in Latin. Even more curious is the fact that Descartes’ name as author was absent from the work and its appendages in the first edition, and he received nothing for the publication except 200 free copies to distribute amongst his colleagues. Several interpretations of these facts have been made. Many scholars suggest that the

38. Mira Ceti, Een Wonderlijke Ster :: Volkssterrenwacht Mira ismael boulliau (1605 94) kondigde in 1667 aan dat de variaties effectief periodischwaren, en dat de ster een periode had van 333 dagen, een waarde die erg http://www.mira.be/articles/sterrenkunde/miraceti/ontdekking.html

De ontdekking van Mira Ceti Mira is echt niet zomaar een sterretje. David Fabricius (1564 - 1617), een Nederlandse amateur-astronoom, ontdekte de ster al op 13 augustus 1596. Fabricius rapporteerde een ster "helderder dan Alpha Arietis", die nochtans van 2de magnitude is. Fabricius kon de ster in geen enkele sterrencatalogus of -atlas terugvinden. Meerdere observaties in september 1596 toonden echter aan dat hij zich niet vergiste. Mira werd zwakker en zwakker, tot ze niet meer met het blote oog gezien kon worden. Fabricius vermoedde dat Mira een nova-ster was, en daarom verdween de ster uit zijn belangstelling. Een terugkerende nova was tot dan toe nog nooit gekend. Toch zou het kunnen dat Fabricius niet de eerste was die Mira zag. Vier jaar vroeger hadden Koreaanse en Chinese waarnemers een "gastster" in het sterrenbeeld Cetus waargenomen, die 15 maanden zichtbaar bleef. Waarschijnlijk is ze niet de hele tijd zichtbaar gebleven, en gaat het hier om waarnemingen van twee opeenvolgende maxima. Later werd Fabricius een pionier in het gebruik van de telescoop, die een tiental jaren na de ontdekking van Mira uitgevonden werd. Hij gebruikte de telescoop vooral voor zonnewaarnemingen.
