SCIENZA E CULTURA UNIVERSITALIA Costantino Sigismondi (ed.) ORBE NOVUS Astronomia e Studi Gerbertiani 1 Universitalia SIGISMONDI, Costantino (a cura di) Orbe Novus / Costantino Sigismondi Roma : Universitalia, 2010 158 p. ; 24 cm. – ( Scienza e Cultura ) ISBN … 1. Storia della Scienza. Storia della Chiesa. I. Sigismondi, Costantino. 509 – SCIENZE PURE, TRATTAMENTO STORICO 270 – STORIA DELLA CHIESA In copertina: Imago Gerberti dal medagliere capitolino e scritta ORBE NOVVS nell'epitaffio tombale di Silvestro II a S. Giovanni in Laterano (entrambe le foto sono di Daniela Velestino). Collana diretta da Rosalma Salina Borello e Luca Nicotra Prima edizione: maggio 2010 Universitalia INTRODUZIONE Introduzione Costantino Sigismondi L’edizione del convegno gerbertiano del 2009, in pieno anno internazionale dell’astronomia, si è tenuta nella Basilica di S. Maria degli Angeli e dei Martiri il 12 maggio, e a Seoul presso l’università Sejong l’11 giugno 2009. La scelta della Basilica è dovuta alla presenza della grande meridiana voluta dal papa Clemente XI Albani nel 1700, che ancora funziona e consente di fare misure di valore astrometrico. Il titolo di questi atti, ORBE NOVUS, è preso, come i precedenti, dall’epitaffio tombale di Silvestro II in Laterano, e vuole suggerire il legame con il “De Revolutionibus Orbium Coelestium” di Copernico, sebbene il contesto in cui queste parole sono tratte vuole inquadrare Gerberto nel suo ministero petrino come il nuovo pastore per tutto il mondo: UT FIERET PASTOR TOTO ORBE NOVVS. Elizabeth Cavicchi del Massachussets Institute of Technology, ha riflettuto sulle esperienze di ottica geometrica fatte da Gerberto con i tubi, nel contesto contemporaneo dello sviluppo dell’ottica nel mondo arabo con cui Gerberto era stato in contatto. -

12/2/2018 Sirius - Wikipedia Coordinates: 06 h 4 5 m 08.9 1 7 3 s, −1 6 ° 4 2 ′ 5 8.01 7 ″ Sirius Sirius (/ˈsɪriəs/, a romanization of Greek Σείριος, Seirios, lit. "glowing" or "scorching") is a star system Sirius A and B and the brightest star in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The system has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single star is a binary star system, consisting of a white main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU.[24] Sirius appears bright because of its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite,[2][25][26] the Sirius system is one of Earth's near neighbours. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's night sky for the next 210,000 years.[27] The position of Sirius (circled). Sirius A is about twice as massive as the Sun (M☉) and has an absolute visual magnitude of 1.42. -

Box. 230, Axum, Ethiopia. Received 24 November, 2017; Accepted 29 January, 2018 One of the major biotic stresses that limits tef yield is insect pests attack. Of these tef, shoot fly is sporadically important insect pest in various tef growing areas of Ethiopia. Evaluation of diversity of tef germplasm in Ethiopia for the reaction tef shoot fly might give a chance to get host plant resistance. The main objective of this study was to assess the genetic variation among tef genotypes for their reaction to tef shoot fly. Field experiment was conducted in 2015 cropping season at Maysiye, Northern Ethiopia. The genotypes were planted in triple lattice design with three replications category of reaction of the tested tef genotypes for their reaction to shoot fly attack was adopted from the rating scale of the IRRI for rice. The study revealed that acc. 17 WJ was found to be the only genotype evaluated as resistant to tef shoot fly Atherigona hyalinipennis species. While the standard checks Quncho and Kora were grouped under the susceptible category, generally 10 tef genotypes were moderately resistance, 19 genotypes were moderately susceptible, 16 genotypes were susceptible, and three genotypes were highly susceptible to tef shoot fly attack. -

Islamic Navigational Knowledge in Ming China 牽星術:明代中國的伊斯蘭導航知識
國立清華大學歷史研究所乙組 碩士論文 Fettering the Stars: Islamic Navigational Knowledge in Ming China 牽星術:明代中國的伊斯蘭導航知識 研究生: 林筱倩 (Hsiao-chien Lin) 學號: 101043513 指導教授: 王憲群 (Hsien-chun Wang) 中華民國一○四年六月 摘要 宋元以來,伊斯蘭世界與中國之間,藉由成熟的海洋技術而有著頻繁貿易的往來, 不同文化之間的交流亦隨之興起。在中國航海史上著名的航海家鄭和(1371‐1433),曾 在十五世紀初期帶領著船隊七次下西洋,航程遠至非洲東岸。歷史材料提及鄭和船隊可能 利用一種名為「牽星術」的導航技術,並使用一種名為「牽星板」的導航儀器。藉由這樣 的儀器,導航員可在夜晚中測量星體和地平線的仰角,並以「指」為測量單位,了解船隻 的位置,以成功達到越洋航行的目的。本論文主旨即在探討這種導航技術與儀器背後的多 文化語言與天文知識的基礎。 我發現在遠洋航行中,水手必須熟練於時間的掌握及方位的辨識,他們藉由觀察星 體的運行來解決這兩個問題。而在印度洋及阿拉伯海之中,使用泰米爾及馬拉姆語的水手 們,便相當善於運用這樣的導航技術。這樣的技術藉由星體仰角的高度來判斷時間,並以 zām 為單位。zām 是一種古代印度計算時間的方式,主要使用特定亮星及月亮做為觀測 同樣為手指的意思。配合 zām 的計時方,(إصبع) 的依據,測量出 「指」,阿拉伯語為 isba 式,得以在汪洋大海中了解航行所花費的時間。水手們更利用在黃昏或清晨時分,藉由亮 星於海平面的位置,來判斷方位。除此之外,在儀器的使用上,類似「牽星板」的航海儀 器有著多種形式的存在。例如,水手在測量的時候,可以使用相同的板子但運用不同的結 點,或者使用不同大小的板子,但繩長不變,亦或是板子大小不同且同時隨結點改變。在 中國史料中,明代李詡《戒庵老人漫筆》等材料顯示,牽星板是一組由十二塊大小不同的 木板組成,顯示華人地區所使用之「牽星板」為板子多塊的類型。而在中國的歷史材料 《武備志》中,除了記載此項航海技術的遺跡,也標示著稱為「針路」的中國傳統航海方 式。此種特殊的繪圖方式,即說明多種文化的導航知識存在於這條航線上。另一方面,我 們亦可從使用方式和儀器的名稱上窺見知識的流動,例如「牽星」一詞在阿拉伯語中為 同為牽引的意思,為一種記憶天體相對位置的特定記憶方法。令人驚喜的,(تكبيل) al‐qaid 是,更多語言關連如同「牽星」和「指」的例子,隨著航海技術的達發而存在於此條航線 中。綜合以上而言,不論從史料或是語言翻譯上,都可以看出跨文化知識傳遞的軌跡。 i 最後,我根據《前聞記》的航程記載,逐步說明鄭和越洋航行之時所使用的導航知 識。發現船隊利用季風做為動力,於冬季利用東北季風出發,並順著夏季的西南季風回程。 此外,從《武備志》裡「過洋牽星圖」的記載中,了解船隊主要仰賴現今北極星、昴宿星 團、北河三、南河三、老人星和南十字星,以確認船隻在固定緯度的航線之上。與此同時, 導航員利用「牽星板」等相似儀器,除了確認船隻所處緯度,更測量星體在天空仰角的變 化,搭配 zām 這種計時方式而得知航行時間。 因此,本論文認為,此類航海技術的發展非一蹴可及,鄭和並非第一位於此條航線 上航行之人,鄭和下西洋所使用的導航技術,乃是一個多文化交流之下的成果,包含著伊 斯蘭、印度、與中國等不同文化的導航技術。因此,鄭和的壯舉,其實是多文化交流之下 的結果。 ii Abstract Beginning from the Song and Yuan Dynasties, Muslim and Chinese ships frequently sailed the south China coast, Southeast Asia, Sri Lanka, and the Persian Gulf, trading goods and cultures. The Chinese naval commander Zheng He 鄭和 (Cheng Ho, 1371‐1433) lead seven expeditions along these sea routes, sailing as far as the east coast of Africa in the early 15th century. Historical sources mention that Zheng He used a navigation method called qianxing shu 牽星術, which employed a particular instrument named qianxing ban 牽星板. -
