Retrieved from ” https: In the final section, the “Gola” or “The Sphere,” Aryabhata goes into great detail describing the celestial relationship between the Earth and the cosmos.
The Aryabhatiya of Aryabhata
Next, Aryabhata says that the product of two equal quantities, the area of a square, and a square are equivalent and likewise, the product of three quantities and a solid with 12 edges are equivalent.
Although the work was influential, there is no definitive English translation. This corresponds to the number of sidereal days given above cf.
However, all the metrical evidence seems to favor the spelling with one t. It has been suggested by some commentators, most notably B.
Is it intended merely as a statement of the popular view? Dasagitika or the Ten Aryzbhatiya Stanzas. As an illustration of Aryabhata’s alphabetical notation take the number of the revolutions of the Moon in a yuga I, 1which is expressed by the word. British Museum Press,pp.
It is more precise than quantities derived by some of the greatest ancient Greek mathematicians. As Fleet remarks,  Aryabhata here claims specifically as his work only three chapters. There are a number of translations but many are incomplete. However, despite the work’s geocentric approach, the Aryabhatiya presents many ideas that are foundational to modern astronomy and mathematics.
This seems to be most unlikely. That is to say, 57, For instance, there are no rules to indicate the method of calculating the ahargana and of finding the mean places of the planets. It must be left to the mathematicians to decide which of the two rules is earlier. They merely serve to refer the consonants which do have numerical values to certain places. Unfortunately it has not been possible to make use of it in the present publication. The sine of the distance between the Sun and the zenith at midday of the equinoctial day is the equinoctial sine.
Aryabhatiya – Wikipedia
Later writers attack him bitterly on this point. Perhaps this is from whence Aryabhata estimated the circumference of the Earth.
At least twelve notable commentaries were written for the Aryabhatiya ranging from the time he was still alive c. University of Chicago Press: He mentions proportions of aryabhstiya with respect to shadows. Such criticism would not arise in regard to mathematical matters which had nothing to do with theological tradition. The number of revolutions of Jupiter multiplied englisy 12 are the years of Jupiter beginning with Asvayuja.
A History of Mathematics. His effort to bring Aryabhata into agreement with the views of most other Indian astronomers seems to be misguided ingenuity.
The east and west line and the north and south line and the perpendicular from zenith to nadir intersect in the place where the observer is. There are stanzas in the Aryabhatiya.
Has its wording been changed as has been done with I, 4? Even more mind-boggling to modern day readers is the fact that these numbers would have been written out as alpha-numeric words.
The treatise uses a geocentric model of the solar system, in which the Sun and Moon are each carried by epicycles which in turn revolve around the Earth.
It is not a complete and detailed working manual of mathematics and astronomy. Such, indeed, is Aryabhata’s usage, and such a statement is really necessary in order to avoid ambiguity, but the words do not seem to warrant the translation given by Rodet. The largest number used by Aryabhata himself 1, 1 runs to only ten places. The avarga letters are those from y to hwhich are not so arranged in groups. The second through ninth stanzas go on to describe the sizes and paths of celestial bodies.
Aryabhata’s formulas for finding these presuppose knowledge of the quadratic equation.
He then gives an overview of his astronomical findings. While some of the aryabhatiyx have a logical flow, some do not, and its unintuitive structure can make it difficult for a casual reader to follow. But if the intention was that of stating that the product of the quotient and an assumed number, and the difference between the remainders, are to be added below the quotients to form a chain the thought is expressed in a very curious way. The translation must remain uncertain until further evidence bearing on the meaning of antya can be produced.
Sukumar Ranjan Das  remarks that two instruments are named in this stanza the gola and the cakra.
Needless to say, the explanation is quite cryptic. I see nothing suspicious in the discrepancy as Kaye does. Whatever the meaning may be, the passage is of no consequence for the numbers actually engliwh with by Aryabhata in this treatise.
