Sulbasutra
The ''Shulva Sutras'' or ''Śulbasūtras'' (Sanskrit: शुल्बसूत्र; ': "string, cord, rope") are sutra texts belonging to the Śrauta ritual and containing geometry related to fire-altar construction. Purpose and origins The Shulba Sutras are part of the larger corpus of texts called the Shrauta Sutras, considered to be appendices to the Vedas. They are the only sources of knowledge of Indian mathematics from the Vedic period. Unique fire-altar shapes were associated with unique gifts from the Gods. For instance, "he who desires heaven is to construct a fire-altar in the form of a falcon"; "a fire-altar in the form of a tortoise is to be constructed by one desiring to win the world of Brahman" and "those who wish to destroy existing and future enemies should construct a fire-altar in the form of a rhombus"., p. 387, "Certain shapes and sizes of fire-altars were associated with particular gifts that the sacrificer desired from the gods: 'he who desires heaven is ...

Manava
Manava (c. 750 BC – 690 BC) is an author of the Hindu geometric text of ''Sulba Sutras.'' The Manava Sulbasutra is not the oldest (the one by Baudhayana is older), nor is it one of the most important, there being at least three Sulbasutras which are considered more important. Historians place his lifetime at around 750 BC. Manava would have not have been a mathematician in the sense that we would understand it today. Nor was he a scribe who simply copied manuscripts like Ahmes. He would certainly have been a man of very considerable learning but probably not interested in mathematics for its own sake, merely interested in using it for religious purposes. Undoubtedly he wrote the ''Sulbasutra'' to provide rules for religious rites and it would appear almost a certainty that Manava himself would be a Hindu Hindus (; ) are people who religiously adhere to Hinduism.Jeffery D.

Vedi (altar)
''Vedi'' () is the sacrificial altar in the Vedic religion. Such altars were an elevated outdoor enclosure, generally strewed with Kusha grass, and having receptacles for the sacrificial fire; it was of various shapes, but usually narrow in the middle. They were used in various types of Yajna rituals, of which the lengthiest was the ''agnicayana'', lasting twelve days. In Vedic times, offerings, often including animals, were burnt in the fire, and fully consumed by it. This contrasts with modern Hindu offerings to gods, which are all vegetable, and are preserved to be consumed by the devotees (which was also the case in other religions, such as ancient Greek religion). Fire altars remain part of the rituals in some Hindu festivals and rites of passage; in particular circling around a sacred fire ('' saptapadi'') remains an essential part of Hindu weddings. Although Agni, the Vedic god of fire, has an important place in the mandala setting out the plan in Hindu temple arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalpa (Vedanga)
Kalpa ( sa, कल्प) means "proper, fit" and is one of the six disciplines of the Vedānga, or ancillary science connected with the Vedas – the scriptures of Hinduism. This field of study is focused on the procedures and ceremonies associated with Vedic ritual practice.James Lochtefeld (2002), "Kalpa" in The Illustrated Encyclopedia of Hinduism, Vol. 1: A–M, Rosen Publishing, , p. 339. The major texts of Kalpa Vedanga are called ''Kalpa Sutras'' in Hinduism. The scope of these texts includes Vedic rituals, rites of passage rituals associated with major life events such as birth, wedding and death in family, as well as personal conduct and proper duties in the life of an individual. Most Kalpasutras texts have experienced interpolation, changes and consequent corruption over their history, and Apasthamba Kalpasutra ancillary to the Yajurveda may be the best preserved text in this genre. Kalpa Sutras are also found in other Indian traditions, such as Jainism. Etymology K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Mathematics
Indian mathematics emerged in the Indian subcontinent from 1200 BCE until the end of the 18th century. In the classical period of Indian mathematics (400 CE to 1200 CE), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, and Varāhamihira. The decimal number system in use today: "The measure of the genius of Indian civilisation, to which we owe our modern (number) system, is all the greater in that it was the only one in all history to have achieved this triumph. Some cultures succeeded, earlier than the Indian, in discovering one or at best two of the characteristics of this intellectual feat. But none of them managed to bring together into a complete and coherent system the necessary and sufficient conditions for a number-system with the same potential as our own." was first recorded in Indian mathematics. Indian mathematicians made early contributions to the study of the concept of zero as a number,: "...our decimal system, which (by t ...

Baudhayana
The (Sanskrit: बौधायन) are a group of Vedic Sanskrit texts which cover dharma, daily ritual, mathematics and is one of the oldest Dharma-related texts of Hinduism that have survived into the modern age from the 1st-millennium BCE. They belong to the ''Taittiriya'' branch of the Krishna Yajurveda school and are among the earliest texts of the genre.. In relative chronology, they predate Apastamba, Āpastamba, which is dated by Robert Lingat to the ''sutra'' period proper, between c. 500 to 200 BCE. Robert Lingat, The Classical Law of India, (Munshiram Manoharlal Publishers Pvt Ltd, 1993), p. 20 The Baudhayana sūtras consist of six texts: # the Baudhayana Shrauta Sutra, , probably in 19 (questions), # the in 20 (chapters), # the in 4 , # the Grhyasutra, Grihyasutra in 4 , # the Dharmasutra, in 4 and # the Sulba Sutras, in 3 .

Apastamba
''Āpastamba Dharmasūtra'' (Sanskrit: आपस्तम्ब धर्मसूत्र) is a Sanskrit text and one of the oldest Dharma-related texts of Hinduism that have survived into the modern age from the 1st-millennium BCE. It is one of three extant Dharmasutras texts from the Taittiriya school of Krishna Yajurveda, the other two being ''Baudhayana Dharmasutra'' and ''Hiranyakesin Dharmasutra''. The ''Apastamba Dharmasutra'' is part of ''Apastamba Kalpasutra'' collection, along with ''Apastamba Shrautasutra'' and ''Apastamba Grihyasutra''. One of the best preserved ancient texts on Dharma, it is also notable for mentioning and citing views of ten ancient experts on Dharma, which has led scholars to conclude that there existed a rich genre of Dharmasutras text in ancient India before this text was composed. Authorship, location and dates The Dharmasutra is attributed to Apastamba, the founder of a Shakha (Vedic school) of Yajurveda. According to the Hindu tradition, Apa ...

Isosceles
In geometry, an isosceles triangle () is a triangle that has two sides of equal length. Sometimes it is specified as having ''exactly'' two sides of equal length, and sometimes as having ''at least'' two sides of equal length, the latter version thus including the equilateral triangle as a special case. Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the faces of bipyramids and certain Catalan solids. The mathematical study of isosceles triangles dates back to ancient Egyptian mathematics and Babylonian mathematics. Isosceles triangles have been used as decoration from even earlier times, and appear frequently in architecture and design, for instance in the pediments and gables of buildings. The two equal sides are called the legs and the third side is called the base of the triangle. The other dimensions of the triangle, such as its height, area, and perimeter, can be calculated by simple formulas from the lengths of the legs and ...

Varaha
Varaha ( sa, वराह, , "boar") is an avatar of the Hindu god Vishnu, in the form of a boar. Varaha is generally listed as third in the Dashavatara, the ten principal avatars of Vishnu. Varaha is most commonly associated with the legend of lifting the Earth (personified as the goddess Bhudevi) out of the cosmic ocean. When the asura Hiranyaksha stole the earth and hid her in the primordial waters, Vishnu appeared as Varaha to rescue her. Varaha slew the asura, and retrieved the Earth from the ocean, lifting it on his tusks, and restored Bhudevi to her place in the universe. Varaha may be depicted as completely a boar or in an anthropomorphic form, with a boar's head and the human body. His consort, Bhudevi, the personified Earth, is often depicted as a young woman, lifted by Varaha. Etymology and other names The deity Varaha derives its name from the Sanskrit word ''varāha'' (Devanagari: वराह, ) meaning "boar" or "wild boar". The word ''varāha'' is from P ...

Pythagorean Theorem
In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides ''a'', ''b'' and the hypotenuse ''c'', often called the Pythagorean equation: :a^2 + b^2 = c^2 , The theorem is named for the Greek philosopher Pythagoras, born around 570 BC. The theorem has been proven numerous times by many different methods – possibly the most for any mathematical theorem. The proofs are diverse, including both geometric proofs and algebraic proofs, with some dating back thousands of years. When Euclidean space is represented by a Cartesian coordinate system in analytic geometry, Euclidean distance satisfies the Pythagorean relation: the squared dist ...

Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...
