Pañcasiddhāntikā
''Pancha-siddhantika'' (IAST: ''Pañca-siddhāntikā'') is a 6th-century CE Sanskrit- language text written by astrologer-astronomer Varāhamihira in present-day Ujjain, India. It summarizes the contents of the treatises of the five contemporary schools of astronomy (siddhantas) prevalent in India. Date The text refers to the Shaka year 427, which corresponds to 505 CE. Indian writers on astrology and astronomy generally chose an epoch year close to the date of composition of their texts, in order to facilitate correct astronomical calculations. Thus, 505 CE was most probably the year in which Varāhamihira composed ''Pancha-Siddhantaka'' or began planning it. The writings of both Varāhamihira and his commentator Utpala suggest that the text was Varāhamihira's first work. However, some scholars believe that 505 CE was the year of Varāhamihira's birth or of another important event in his life. This is because according to Amaraja, the author of a commentary on Brahmagupta's '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IAST
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Brahmic family, Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Sir Charles Trevelyan, 1st Baronet, Charles Trevelyan, William Jones (philologist), William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva International Congress of Orientalists, Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars. Usage Scholars commonly use IAST in publications that cite textual material in Sanskrit, Pāḷi and other classical Indian languages. IAST is also used for major e-text repos ...

Brahmagupta
Brahmagupta ( – ) was an Indian Indian mathematics, mathematician and Indian astronomy, astronomer. He is the author of two early works on mathematics and astronomy: the ''Brāhmasphuṭasiddhānta'' (BSS, "correctly established Siddhanta, doctrine of Brahma", dated 628), a theoretical treatise, and the ''Khandakhadyaka'' ("edible bite", dated 665), a more practical text. In 628 CE, Brahmagupta first described gravity as an attractive force, and used the term "gurutvākarṣaṇam (गुरुत्वाकर्षणम्)" in Sanskrit to describe it. He is also credited with the first clear description of the quadratic formula (the solution of the quadratic equation)Bradley, Michael. ''The Birth of Mathematics: Ancient Times to 1300'', p. 86 (Infobase Publishing 2006) in his main work, the ''Brāhma-sphuṭa-siddhānta''.

Otto E
Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants '' Audo'', '' Odo'', '' Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded from the 7th century ( Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was ''auda-'' (as in e.g. '' Audaþius''), the Anglo-Saxon form was ''ead-'' (as in e.g. '' Eadmund''), and the Old Norse form was '' auð-''. Due to Otto von Bismarck, the given name ''Otto'' was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during the 1880s to 1890s, remaining in the top 100 most popular masculine given names in the US throughout 1880–1898, but ...

Lost Literary Work
A lost literary work (referred throughout this article just as a lost work) is a document, literary work, or piece of multimedia, produced of which no surviving copies are known to exist, meaning it can be known only through reference, or literary fragments. This term most commonly applies to works from the classical world, although it is increasingly used in relation to modern works. A work may be lost to history through the destruction of an original manuscript and all later copies. Works—or, commonly, small fragments of works—have survived by being found by archaeologists during investigations, or accidentally by laypersons such as, for example, the finding Nag Hammadi library scrolls. Works also survived when they were reused as bookbinding materials, quoted or included in other works, or as palimpsests, where an original document is imperfectly erased so the substrate on which it was written can be reused. The discovery, in 1822, of Cicero's '' De re publica'' was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paulisa Siddhanta
The Pauliṣa Siddhānta (literally, "The scientific-treatise of Pauliṣa Muni") refers to multiple Indian astronomical treatises, at least one of which is based on a Western source. "'' Siddhānta''" literally means "doctrine" or "tradition". It is often mistakenly thought to be a single work and attributed to Paul of Alexandria (c. 378 CE). However, this notion has been rejected by other scholars in the field, notably by David Pingree who stated that "...the identification of Paulus Alexandrinus with the author of the ''Pauliṣa Siddhānta'' is totally false". Similarly, K. V. Sarma writes that it is from a Greek source, known only as Pauliṣa. Alberuni wrote that the Siddhanta is based on the teaching of a Greek named Paulus. The earlier Pauliṣa-siddhānta dates from the third or fourth century, and the later Pauliṣa-siddhānta from the eighth century. Similar to the Yavanajātaka ("The Sayings of the Greeks"), the Pauliṣa Siddhānta is an example of Hellenistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surya Siddhanta
The ''Surya Siddhanta'' (; ) is a Sanskrit treatise in Indian astronomy dated to 4th to 5th century,Menso Folkerts, Craig G. Fraser, Jeremy John Gray, John L. Berggren, Wilbur R.
