Leading astronomers of this period were Aryabhata I (born A.D. 476), Varahamihira (6th century A.D.), Bhaskara I (born c. A.D. 600), Brahmagupta (born c. A.D. 598), and Bhaskara II (born A.D. 1114). Besides the compilation work of Varahamihira, the immortal works of this period were Aryabhatia (by Aryabhata I), Brahmasphuta-siddhanta (by Brahmagupta) and Siddhanta-Shiromani (by Bhaskara II). with the help of commentaries. By the age of 15 he mastered the rules for calculating the ephemerides (tables showing the positions of heavenly bodies at regular intervals in time) of the planets. While calculating the positions of the planets he found that neither the stars appeared on the horizon at the right moment nor could the planets be seen in the right places. He began to observe and calculate the movement of heavenly bodies night after night. At the age of 23 he began to note down systematically the results of his observations. The journal Knowledge which reviewed the book in 1899 wrote: Pathani Samanta made contributions to the following four important aspects of astronomy:
(1) Observations
(2) Calculation
(3) Method of measurement and instrumentation
(4) Theory and models
Siddhanta-Darpana wrote: The instruments used for his practical observation of the night sky were made by himself indigenously. His instruments which were mostly made up of wood and bamboo pieces can be broadly classified into three categories :

VPNEWS PARTING THOUGHTS (II) To continue from where we left off last time, Vigyan Prasar can really make a difference to the overall science popularisation scene in the country! It has all the essential ingredients, in the form of major programmes/efforts, I mentioned last time, to transform itself into a powerhouse of incredible and unimaginable strengths capable of delivering unheard of results! Each one of the VP's major programmes referred to earlier, if handled appropriately, could develop into an independent, self-sustaining entity in its own right, under the overall VP umbrella, with greatly enhanced output. What would that mean in terms of the goals we are seeking to achieve? Vigyan Prasar books would also be distributed worldwide in many countries and also in many other non-Indian languages. Dream-2047 would develop into a very popular science magazine with a large circulation and several other language editions, besides Hindi and English. .

Geometry in Ancient and Medieval India/T.A. Sarasvati Amma. 2nd revised edition. 1999, 277 p., ISBN 81-208-1344-8. "This book is a geometrical survey of the Samskrit and Prakrt scientific and quasi-scientific literature of India beginning with the Vedic literature and ending with the early part of the 17th century. It deals in detail with the Sulbasutras in the Vedic literature, with the mathematical parts of Jaina Canonical works and of the Hindu Siddhantas and with the contributions to geometry made by the astronomer mathematicians Aryabhata I & II, Sripati, Bhaskara I & II, Sangamagrama Madhava, Paramesvara, Nilakantha, his disciples and a ahost of others. The works of the mathematicians Mahavira, Sridhara and Narayana Pandita and the Bakshali Manuscript have also been studied. "The work seeks to explode the theory that the Indian mathematical genius was predominantly algebraic and computational and that it eschewed proofs and rationales. There was a school in India which delighted to demonstrate even algebraical results geometrically. In their search for a sufficiently good approximation for the value of py Indian mathematicians had discovered the tool of integration, which they used equally effectively for finding the surface area and volume of a sphere and in other fields. This discovery of integration was the sequel of the inextricable blending of geometry and series mathematics." (jacket) Return to History and Politics of India Catalogue: New Additions

THE NATURE OF MATTER
Previous Page
Contents of the Book Next Page Indian Cosmology Reflections in Religion and Metaphysics A. K. Chakravarty The exact origin of astronomical studies in India is not known to us though it is fairly clear that it eventually formed part of ancient Vedic people. The earliest text on this subject now available, Vedanga Jyotisa , aims at determining the most suitable time for performing a yajna in consideration of the luni-solar-stellar situation at that time. The subject was based on so crude astronomical parameters that its failure could not escape the notice of any sky-watcher, till then it was never questioned by anybody perhaps because of its association with religious yajnas . This scheme of astronomy survived for some 2000 years. In later India, these parameters were scraped, scope of astronomy was extended to include natural phenomena, like, eclipses, identification of planets and formulations of their motions, etc., till then astronomers often invoked metaphysics to explain cosmological facts. It occurs to us that the general people of that period in that class-ridden society was more interested in earning punyaphala through religious functions than acquiring pure knowledge. Astronomers could not or did not ignore this sentiment and so, to honour this sentiment, they found it necessary to blend religion and metaphysics with cosmology in an astronomical background. Science in ancient times had to be supplemented by speculative materials and was thus mixed up with myths and metaphysics.

    Hinduism Intro Christian Missionaries Great Hindu Personalities ... Links Great Hindu Personalities Aryabhata I (476 - 550 A.D.) - mathematician and astronomer. He is "the author of the first of the later sidhantas [mathematical treatises] called Aryabhatiyam which sketches his mathematical, planetary, and cosmic theories. This book is divided into four chapters: (i) the astronomical constants and the sine table (ii) mathematics required for computations (iii) division of time and rules for computing the longitudes of planets using eccentrics and epicycles (iv) the armillary sphere, rules relating to problems of trigonometry and the computation of eclipes... Aryabhata took the earth to spin on its axis; this idea appears to have been his innovation... That Aryabhata was aware of the relativity of motion is clear from this passage in his book, 'Just as a man in a boat sees the trees on the bank move in the opposite direction, so an observer on the equator sees the stationary stars as moving precisely toward the west.'" "The mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry and spherical trigonometry. It also contains continued fractions, quadratic equations, sums of power series and a table of sines." Aryabhata gave a value for pi correct to five digits (3.1416); he also gave a close approximation for the circumference of the Earth (62832 miles); believed that the planets and the Moon reflected sunlight and also that the orbits of the plantes were ellipses.

    Sulbasutra Geometry
    For Prof. W. Casselman
    By Susanna Kong
    Math 309 April 2001
    Introduction
    The basis and inspiration for the whole of Indian mathematics is geometry. The beginnings of algebra can be traced to the constructional geometry of the Vedic priests preserved in the Sulbasutras , a manual of geometrical constructions from the 5 th to the 8 th centuries. Earlier remnants of geometrical knowledge of the Indus Valley Civilisation can be found in excavations at Harappa and Mohenjo-daro where there is evidence of circle-drawing instruments from as early as 2500 B.C.E. (Amma 1) Early geometry of the Sulbasutras was based on religious needs with regards to the construction of altars such as agnicitis, vedis, mandapas etc. that are required for sacrificial ritual (Kulkarni 19, Amma 3). The history of Indian geometry can be divided into three distinct periods: pre-Aryan, such as excavated in Indus Valley. Vedic or Sulbasutra post-Christian. Evidence of the pre-Aryan period includes well-planned towns and geometric designs including circles, squares and triangles. A link between this and the Vedic period can be found in the motif of a rectangle with the four sides curved inwards resembling a stretched hide; in the former period it can be seen as a decorative pattern while in the later period it is seen in the shape of the sacrificial altars or vedi . The vedi as well as the fireplaces or agni had such exact measurements and geometric shapes that they were codified and became the Sulbasutras . However, it is not known from how far back such knowledge originated as the sacrificial act is as old as the Vedas or older (Amma 5).
