Fibonacci Numbers
In mathematics, the Fibonacci numbers, commonly denoted , form a sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the first few values in the sequence are: :0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144. The Fibonacci numbers were first described in Indian mathematics, as early as 200 BC in work by Pingala on enumerating possible patterns of Sanskrit poetry formed from syllables of two lengths. They are named after the Italian mathematician Leonardo of Pisa, later known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book ''Liber Abaci''. Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the ''Fibonacci Quarterly''. Applications of Fibonacci numbers include co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hemachandra
Hemachandra was a 12th century () Indian Jain saint, scholar, poet, mathematician, philosopher, yogi, grammarian, law theorist, historian, lexicographer, rhetorician, logician, and prosodist. Noted as a prodigy by his contemporaries, he gained the title ''kalikālasarvajña'', "the knower of all knowledge in his times" and ''father of Gujarati language''. Born as Changadeva, he was ordained in the Śvētāmbara school of Jainism in 1110 and took the name Somachandra. In 1125 he became an adviser to King Kumarapala and wrote ''Arhanniti'', a work on politics from a Jain perspective. He also produced ''Trishashti-shalaka-purusha-charita'' (“Deeds of the 63 Illustrious Men”), a Sanskrit epic poem on the history of important figures of Jainism. Later in his life, he changed his name to Hemachandra. Early life Hemachandra was born in Dhandhuka, in present-day Gujarat, on Kartika Sud Purnima (the full moon day of Kartika month).

Mora (linguistics)
A mora (plural ''morae'' or ''moras''; often symbolized μ) is a basic timing unit in the phonology of some spoken languages, equal to or shorter than a syllable. For example, a short syllable such as ''ba'' consists of one mora (''monomoraic''), while a long syllable such as ''baa'' consists of two (''bimoraic''); extra-long syllables with three moras (''trimoraic'') are relatively rare. Such metrics are also referred to as syllable weight. The term comes from the Latin word for "linger, delay", which was also used to translate the Greek word χρόνος : ''chrónos'' (time) in its metrical sense. Formation The general principles for assigning moras to segments are as follows (see Hayes 1989 and Hyman 1985 for detailed discussion): # A syllable onset (the first consonant or consonants of the syllable) does not represent any mora. # The syllable nucleus represents one mora in the case of a short vowel, and two morae in the case of a long vowel or diphthong.

Virahanka
Virahanka (Devanagari: विरहाङ्क) was an Indian prosodist who is also known for his work on mathematics. He may have lived in the 6th century, but it is also possible that he worked as late as the 8th century. His work on prosody builds on the ''Chhanda-sutras'' of Pingala (4th century BCE), and was the basis for a 12th-century commentary by Gopala. He was the first to propose the so-called Fibonacci Sequence In mathematics, the Fibonacci numbers, commonly denoted , form a integer sequence, sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones.

Natya Shastra
The ''Nāṭya Śāstra'' (, ''Nāṭyaśāstra'') is a Sanskrit treatise on the performing arts. The text is attributed to sage Bharata Muni, and its first complete compilation is dated to between 200 BCE and 200 CE, but estimates vary between 500 BCE and 500 CE. The text consists of 36 chapters with a cumulative total of 6000 poetic verses describing performance arts. The subjects covered by the treatise include dramatic composition, structure of a play and the construction of a stage to host it, genres of acting, body movements, make up and costumes, role and goals of an art director, the musical scales, musical instruments and the integration of music with art performance. The ''Nāṭya Śāstra'' is notable as an ancient encyclopedic treatise on the arts, one which has influenced dance, music and literary traditions in India. It is also notable for its aesthetic Rasa (aesthetics), "Rasa" theory, which asserts that entertainment is a desired effect of performa ...

Bharata Muni
Bharata Muni (Hindi: भरत मुनि) was an ancient sage who the musical treatise '' Natya Shastra'' is traditionally attributed to.

He is dated to between 200 BCE and 200 CE, but estimates vary between 500 BCE and 500 CE.Dace, W. (1963). "The Concept of "Rasa" in Sanskrit Dramatic Theory". Educational Theatre Journal. 15 (3): 249. The ''Nāṭya Śāstra'' is notable as an ancient encyclopedic treatise on the arts, which has influenced dance, music and literary traditions in India. It is also notable for its aesthetic "Rasa" theory, which asserts that entertainment is the desired effect of performance arts but not the primary goal and that the primary goal is to transport the individual in the audience into another parallel reality, full of wonder, where he experiences the essence of his own consc ...

Sanskrit Prosody
Sanskrit prosody or Chandas refers to one of the six Vedangas, or limbs of Vedic studies.James Lochtefeld (2002), "Chandas" in The Illustrated Encyclopedia of Hinduism, Vol. 1: A-M, Rosen Publishing, , page 140 It is the study of poetic metres and verse in Sanskrit. This field of study was central to the composition of the Vedas, the scriptural canons of Hinduism, so central that some later Hindu and Buddhist texts refer to the Vedas as ''Chandas''. The Chandas, as developed by the Vedic schools, were organized around seven major metres, and each had its own rhythm, movements and aesthetics. Sanskrit metres include those based on a fixed number of syllables per verse, and those based on fixed number of morae per verse. Extant ancient manuals on Chandas include Pingala's ''Chandah Sutra'', while an example of a medieval Sanskrit prosody manual is Kedara Bhatta's ''Vrittaratnakara''. The most exhaustive compilations of Sanskrit prosody describe over 600 metres. This is a subst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
