Vyatipāta
In Indian astronomy and astrology, vyatipāta and vaidhṛti (or, vaidhṛta) are two moments in the regular motion of the sun and the moon in the zodiac characterized by their certain special relative positions. These terms are also used to denote two of the 27 ''Nityayoga''-s: ''vyatipāta'' is the 17th ''nityayoga'' and ''vaidhṛti'' is the 27th ''nityayoga''. Definitions Sūrysiddhānta defines ''vyatipāta'' and ''vaidhṛti'' as follows (''Sūrysiddhānta'' Chapter IX ''Pātādhikāra'' verses 1 and 2): * When the sun and moon are upon the same side of either solstice, and when, the sum of their longitudes being a circle, they are of equal declination, it is styled ''vaidhṛta''. * When the moon and sun are upon opposite sides of either solstice, and their minutes of declination are the same, it is ''vyatipāta'', the sum of their longitudes being a half-circle. The term ''pāta'' in the present context means literally "fall," and hence also either "fault, transgression," ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nityayoga
In Indian astronomy, ''yoga'' (also called ''nityayoga'') is a period of time, of varying lengths, during which the sum of the ''nirayana'' longitudes of the Sun and the Moon increases by an amount of 13 degrees 20 minutes (or, equivalently, 800 minutes). While considering the sum, when the sum is 360 degrees or more, then 360 degrees is subtracted from the sum to make the sum an angle between 0 degree and 360 minutes. Consider a moment T1 when the sum of the longitudes of the Sun and the Moon is 0 degree and let T2 be the next immediate moment when the sum of the longitudes of the Sun and the Moon is 13 degree 20 minutes. The duration of time between the moments T1 and T2 is the first ''yoga''. Similarly, let the next immediate moment when the sum of the longitudes of the Sun and Moon is 26 degrees 40 minutes. The duration of time between the moments T2 and T3 is the second ''yoga''. The third, fourth and higher ''yoga''-s are defined in a similar way. Since 27 X 13 degrees 20 min ...

Patas01
The common patas monkey (''Erythrocebus patas''), also known as the hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. Taxonomy There is some confusion surrounding if there are valid subspecies, with some listing four, others three, and others listing two: the western ''Erythrocebus patas patas'' (with a black nose) and the eastern ''E. patas pyrrhonotus'' (with a white nose). However, it was later discovered that the nose colour used to separate these subspecies could change to white during pregnancy in females, as well as in general as animals aged, and ''E. patas pyrrhonotus'' in Kenya often did not have white noses, thus ''Mammal Species of the World'' has classified ''E. patas'' as a monotypic species. The genus status of the species has previously been in flux. Colin Groves first argued the species was closely related to ''Cercopithecus aethiops'' in 1989, based on anatomical morphology.

Astrology
Astrology is a range of Divination, divinatory practices, recognized as pseudoscientific since the 18th century, that propose that information about human affairs and terrestrial events may be discerned by studying the apparent positions of Celestial objects in astrology, celestial objects. Different cultures have employed forms of astrology since at least the 2nd millennium BCE, these practices having originated in Calendrical calculation, calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Most, if not all, cultures have attached importance to what they observed in the sky, and some—such as the Hindu astrology, Hindus, Chinese astrology, Chinese, and the Maya civilization, Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, fr ...

Hindu Astronomy
Astronomy has a long history in the Indian subcontinent, stretching from pre-historic to modern times. Some of the earliest roots of Indian astronomy can be dated to the period of Indus Valley civilisation or earlier. Astronomy later developed as a discipline of Vedanga, or one of the "auxiliary disciplines" associated with the study of the Vedas dating 1500 BCE or older. The oldest known text is the ''Vedanga Jyotisha'', dated to 1400–1200 BCE (with the extant form possibly from 700 to 600 BCE). Indian astronomy was influenced by Greek astronomy beginning in the 4th century BCEHighlights of Astronomy, Volume 11B: As presented at the XXIIIrd General Assembly of the IAU, 1997.
