Vedanga Jyotisha
''Vedanga Jyotisha'' (), or ''Jyotishavedanga'' (), is one of earliest known Indian texts on astrology ('' Jyotisha''). The extant text is dated to the final centuries BCE, but it may be based on a tradition reaching back to about 700-600 BCE. The text is foundational to ''Jyotisha'', one of the six Vedanga disciplines. Its author is traditionally named as Lagadha. Textual history The dating of the ''Vedanga Jyotisha'' is relevant for the dating of the Vedic texts. The ''Vedanga Jyotisha'' describes the winter solstice for the period of ca. 1400 BCE. This description has been used to date the ''Vedanga Jyotisha''. According to Michael Witzel, the question is "whether the description as given in the Jyotisha is also the date of the text in which it is transmitted. It is written in two recensions – Rigveda The ''Rigveda'' or ''Rig Veda'' (, , from wikt:ऋच्, ऋच्, "praise" and wikt:वेद, वेद, "knowledge") is an ancient Indian Miscellany, collec ...

Indian Science Congress Association
Indian Science Congress Association (ISCA) is a premier scientific organisation of India with headquarters at Kolkata, West Bengal. The association started in the year 1914 in Calcutta and it meets annually in the first week of January. It has a membership of more than 30,000 scientists. The first Indian Science Congress was held in 1914 at the Asiatic Society in Calcutta. After attracting various speech-related controversies in recent years, the association established a policy that requires speakers at future conferences to be vetted and scrutinizes the content of their talks. Several prominent Indian and foreign scientists, including Nobel laureates, attend and speak in the congress. Genesis The Indian Science Congress Association (ISCA) owes its origin to the foresight and initiative of two British chemists, namely, Professor J. L. Simonsen and Professor P. S. MacMahon. It occurred to them that scientific research in India might be stimulated if an annual meeting of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aryabhata
Aryabhata ( ISO: ) or Aryabhata I (476–550 CE) was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His works include the '' Āryabhaṭīya'' (which mentions that in 3600 '' Kali Yuga'', 499 CE, he was 23 years old) and the ''Arya- siddhanta''. For his explicit mention of the relativity of motion, he also qualifies as a major early physicist. Biography Name While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the " bhatta" suffix, his name is properly spelled Aryabhata: every astronomical text spells his name thus, including Brahmagupta's references to him "in more than a hundred places by name". Furthermore, in most instances "Aryabhatta" would not fit the metre either. Time and place of birth Aryabhata mentions in the ''Aryabhatiya'' that he was 23 years old 3,600 years into the '' Kali Yuga'', but this is not to mean that the text was composed at that ti ...

Bhāskara I
Bhāskara (; commonly called Bhāskara I to avoid confusion with the 12th-century mathematician Bhāskara II) was a 7th-century Indian mathematician and astronomer who was the first to write numbers in the Hindu–Arabic decimal system with a circle for the zero, and who gave a unique and remarkable rational approximation of the sine function in his commentary on Aryabhata's work. This commentary, ''Āryabhaṭīyabhāṣya'', written in 629, is among the oldest known prose works in Sanskrit on mathematics and astronomy. He also wrote two astronomical works in the line of Aryabhata's school: the ''Mahābhāskarīya'' ("Great Book of Bhāskara") and the ''Laghubhāskarīya'' ("Small Book of Bhāskara"). On 7 June 1979, the Indian Space Research Organisation launched the Bhāskara I satellite, named in honour of the mathematician. Biography Little is known about Bhāskara's life, except for what can be deduced from his writings. He was born in India in the 7th century, and wa ...

Varāhamihira
Varāhamihira ( 20/21 March 505 – 587), also called Varāha or Mihira, was an ancient Indian astrologer-astronomer who lived in or around Ujjain in present-day Madhya Pradesh, India. Date Unlike other prominent ancient Indian astronomers, Varāhamihira does not mention his date. However, based on hints in his works, modern scholars date him to the 6th century CE; possibly, he also lived during the last years of the 5th century. In his '' Pancha-siddhantika'', Varāhamihira refers to the year 427 of the ''Shaka-kala'' (also ''Shakendra-kala'' or ''Shaka-bhupa-kala''). Identifying this calendar era with the Shaka era places Varāhamihira in the 505 CE. Alternative theories identify this calendar era with other eras, placing him before the 5th century CE. However, these theories are inaccurate, as Varāhamihira must have lived after Aryabhata (born 476 CE), whose work he refers to. The particulars of the date mentioned by Varāhamihira - Shukla '' pratipada'' of the Chai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eclipse
An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a ''syzygy''. An eclipse is the result of either an '' occultation'' (completely hidden) or a ''transit'' (partially hidden). A "deep eclipse" (or "deep occultation") is when a small astronomical object is behind a bigger one. "What is a deep eclipse? The smaller star is behind the bigger star" The term ''eclipse'' is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the ...
