Extractions: International Study Group on the Relations Between HISTORY and PEDAGOGY of MATHEMATICS NEWSLETTER An Affiliate of the International Commission on Mathematical Instruction: No. 48, November 2001 A particular rule for finding the arc length of a bow-figure (i.e. segment of a circle) has been found on an ancient Babylonian tablet. fig.1 Let s, c, h be, respectively, the length of the arc PNQ (see fig.1), chord PQ, and the arrow or height MN of the circular segment (assumed to be not greater than a semicircle). Then the formula extracted from the procedure given in the old Babylonian text BM85194 (dated about 1600BC) is equivalent to s c h Actually, the scribe used (1) for finding h (without specifying it so) correctly equal to 10 from given s = 60 and c = 50. The true formula is c h d h But the exact formula (2) is not expected to be known in that remote pre-trigonometric antiquity and the empirical rule (1) can be regarded to be quite practical. Surprisingly the rule (1) is found preserved in some later traditions (see below). As an application of (1), consider the old common formula

Extractions: Essentially nothing is known of the life of Aryabhata II. Historians have argued about his date and have come up with many different theories. In [1] Pingree gives the date for his main publications as being between 950 and 1100. This is deduced from the usual arguments such as which authors Aryabhata II refers to and which refer to him. G R Kaye argued in 1910 that Aryabhata II lived before al-Biruni but Datta [2] in 1926 showed that these dates were too early. The article [3] argues for a date of about 950 for Aryabhata II's main work, the Mahasiddhanta, but R Billiard has proposed a date for Aryabhata II in the sixteenth century. Most modern historians, however, consider the most likely dates for his main work as around 950 and we have given very approximate dates for his birth and death based on this hypothesis. See [7] for a fairly recent discussion of this topic. The most famous work by Aryabhata II is the Mahasiddhanta which consists of eighteen chapters. The treatise is written in Sanskrit verse and the first twelve chapters form a treatise on mathematical astronomy covering the usual topics that Indian mathematicians worked on during this period. The topics included in these twelve chapters are: the longitudes of the planets, eclipses of the sun and moon, the projection of eclipses, the lunar crescent, the rising and setting of the planets, conjunctions of the planets with each other and with the stars.

Extractions: It is without doubt that mathematics today owes a huge debt to the outstanding contributions made by Indian mathematicians over many hundreds of years. What is quite surprising is that there has been a reluctance to recognise this and one has to conclude that many famous historians of mathematics found what they expected to find, or perhaps even what they hoped to find, rather than to realise what was so clear in front of them. We shall examine the contributions of Indian mathematics in this article, but before looking at this contribution in more detail we should say clearly that the "huge debt" is the beautiful number system invented by the Indians on which much of mathematical development has rested. Laplace put this with great clarity:- The ingenious method of expressing every possible number using a set of ten symbols each symbol having a place value and an absolute value emerged in India. The idea seems so simple nowadays that its significance and profound importance is no longer appreciated. Its simplicity lies in the way it facilitated calculation and placed arithmetic foremost amongst useful inventions. the importance of this invention is more readily appreciated when one considers that it was beyond the two greatest men of Antiquity, Archimedes and Apollonius We shall look briefly at the Indian development of the place-value decimal system of numbers later in this article and in somewhat more detail in the separate article

Extractions: About me Food Arts Places ... Miscellaneous SCIENTIFIC LITERATURE OF ANCIENT INDIA Science is essentially the systematic study of anything. It is a well known fact that science was well developed in ancient India. Science was cultivated by the brahminical schools. It was preserved and written in the form of Sutras - formulae. Later commentaries were written to explain these sutras. A vast collection of scientific literature is available in India of which a few are mentioned here. GRAMMAR The earliest known work on grammar is the Asthadhyi of Panini (circa 4-5 C BC)which refers to previous works. The Vartikas of Katyayana (3 C BC) are the critical, explanatory and commentary works of some rules of Panini. Patanjali's Mahabhasha (2 C BC) is a commentary on the Vartikas. Vakyapadiya of Bhartrihari (7 C AD) is more a work on the philosophy of language. LEXICOGRAPHY (KOSHAS) Koshas were a collection of rare and important works and their meanings. Unlike the modern dictionaries the Koshas were in the form of verses. They were of two types: those of synonyms and those of homonyms. The best known works are Amarasimha's Namalinganushasana (or AMARAKOSHA) - a three section dictionary of synonyms and Shasvata's Anekarthasamuchchaya - a dictionary of homonyms.

Extractions: (Limitations under which Bhakti and Prapatti operate) Certain people exaggerate the efficacy of Prapatti to absurd extents. This chapter seeks to disabuse the views so expressed on certain aspects. ( 1 ) That even though one is born in a lower caste, he becomes one of a higher caste on performing Prapatti. The answer is that so long as the body exists, the caste does not change. EVEN A TEMPLE COW, HOWEVER HOLY IT MIGHT BE, REMAINS ONLY A COW. Even though Sri Krishna eulogized VIDURA a person belonging to the fourth caste, he did not say that he changed his caste. Similarly, even Viswamitra never became a Brahmin. The story regarding his birth shows that since his mother partook of the potion meant for a Brahmin foetus, he was already a Brahmin indeed by birth but his brahminic traits remained eclipsed. This does not mean that one can afford to despise another on the basis of caste. EVEN A PERSON OF THE SO CALLED LOWER CASTE, IF THEY ARE DEVOTEES - DUE

Ramakrishna Rao, B.Sc., M.A., A.M.I.E., C.Eng.(I)., B.L., Introduction The date of Mahabharat is analyzed for determination only based on the Indian astronomical works. The following facts are taken into consideration for such critical study: The Indian astronomers of Siddhantic works and followers have recorded the date of Bharata implying Mahabharat war in particular and starting of Kaliyuga or Era, that is used to reckon the dates of themselves at many places and in conjunction with Saka era in some places later. Aryabhata makes a specific mention about Bharata in his Aryabhatiyam. Most of the scholars including westerners have taken the connotation of it as referring to Mahabharat and in particular Mahabharat war, because, that is considered as the staring point of Kaliyuga / era in Indian astronomy and history too. Therefore, taking the astronomical works - Siddhantas, Tantras and Karanas like - Aryabhatiyam, Mahabhaskariyam, Vatesvara - Siddhanta
