Sexagesimal
Sexagesimal, also known as base 60 or sexagenary, is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for measuring time, angles, and geographic coordinates. The number 60, a superior highly composite number, has twelve factors, namely 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60, of which 2, 3, and 5 are prime numbers. With so many factors, many fractions involving sexagesimal numbers are simplified. For example, one hour can be divided evenly into sections of 30 minutes, 20 minutes, 15 minutes, 12 minutes, 10 minutes, 6 minutes, 5 minutes, 4 minutes, 3 minutes, 2 minutes, and 1 minute. 60 is the smallest number that is divisible by every number from 1 to 6; that is, it is the lowest common multiple of 1, 2, 3, 4, 5, and 6. ''In this article, all sexagesimal digits are represented as decimal numbers, except where otherwise noted. For e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jyotisha
Jyotisha or Jyotishya (from Sanskrit ', from ' “light, heavenly body" and ''ish'' - from Isvara or God) is the traditional Hindu system of astrology, also known as Hindu astrology, Indian astrology and more recently Vedic astrology. It is one of the six auxiliary disciplines in Hinduism, that is connected with the study of the Vedas. The ''Vedanga Jyotisha'' is one of the earliest texts about astronomy within the Vedas. Some scholars believe that the horoscopic astrology practiced in the Indian subcontinent came from Hellenistic influences, however, this is a point of intense debate and other scholars believe that Jyotisha developed independently although it may have interacted with Greek astrology. Following a judgement of the Andhra Pradesh High Court in 2001 which favoured astrology, some Indian universities now offer advanced degrees in Hindu astrology. The scientific consensus is that astrology is a pseudoscience. Etymology Jyotisha, states Monier-Williams, is rooted in ... [...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. The Alberuni wrote that the Siddhanta is based to 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 Hellenis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varāhamihira
Varāhamihira ( 505 – 587), also called Varāha or Mihira, was an ancient Indian astrologer, astronomer, and polymath who lived in Ujjain (Madhya Pradesh, India). He was born at Kapitba in a Brahmin family, in the Avanti region, roughly corresponding to modern-day Malwa (part of Madhya Pradesh, India), to Adityadasa. According to one of his own works, he was educated at Kapitthaka. The Indian tradition believes him to be one of the "Nine Jewels" (Navaratnas) of the court of ruler Yashodharman Vikramaditya of Malwa. However, this claim appears for the first time in a much later text and scholars consider this claim to be doubtful because neither Varahamihira and Vikramaditya lived in the same century nor did Varahamihira live in the same century as some of the other names in the "nine jewels" list such as the much older Kalidasa. Varāhamihira's most notable works were the ''Brihat Samhita'', an encyclopedic, Quote: " ..the new temples and inconography, the science of arch ...

Yuga Cycle
A ''Yuga'' Cycle ( ''chatur yuga'', ''maha yuga'', etc.) is a cyclic age (epoch) in Hindu cosmology. Each cycle lasts for 4,320,000 years (12,000 divine years) and repeats four ''yugas'' (world ages): '' Krita (Satya) Yuga'', ''Treta Yuga'', '' Dvapara Yuga'', and '' Kali Yuga''. As a ''Yuga'' Cycle progresses through the four ''yugas'', each '' yuga's'' length and humanity's general moral and physical state within each ''yuga'' decrease by one-fourth. ''Kali Yuga'', which lasts for 432,000 years, is believed to have started in 3102 BCE. Near the end of ''Kali Yuga'', when virtues are at their worst, a cataclysm and a re-establishment of '' dharma'' occur to usher in the next cycle's ''Satya Yuga'', prophesied to occur by Kalki. There are 71 ''Yuga'' Cycles in a ''manvantara'' (age of Manu) and 1,000 ''Yuga'' Cycles in a ''kalpa'' (day of Brahma). Lexicology A ''Yuga'' Cycle has several names.

Islamic Geography
Medieval Islamic geography and cartography refer to the study of geography and cartography in the Muslim world during the Islamic Golden Age (variously dated between the 8th century and 16th century). Muslim scholars made advances to the map-making traditions of earlier cultures, particularly the Hellenistic geographers Ptolemy and Marinus of Tyre, combined with what explorers and merchants learned in their travels across the Old World ( Afro-Eurasia). Islamic geography had three major fields: exploration and navigation, physical geography, and cartography and mathematical geography. Islamic geography reached its apex with Muhammad al-Idrisi in the 12th century. History Islamic geography began in the 8th century, influenced by Hellenistic geography, combined with what explorers and merchants learned in their travels across the Old World ( Afro-Eurasia).
