In the final section, the "Gola" or "The Sphere," Aryabhata goes into great detail describing the celestial relationship between the Earth and the cosmos. This section is noted for describing the rotation of the Earth on its axis.

It further uses the armillary sphere and details rules relating to problems of trigonometry and the computation of eclipses. Significance[ edit ] 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.

His value for the length of the sidereal year at days 6 hours 12 minutes 30 seconds is only 3 minutes 20 seconds longer than the modern scientific value of days 6 hours 9 minutes 10 seconds.

The result is approximately the circumference of a circle of diameter twenty thousand. By this rule the relation of the circumference to diameter is given. There was also difference in some astronomical parameters.

Gitikapada 13 verses : large units of time—kalpa, manvantra, and yuga—which present a cosmology different from earlier texts such as Lagadha's Vedanga Jyotisha ca. There is also a table of [sine]s jya , given in a single verse. The duration of the planetary revolutions during a mahayuga is given as 4. Kalakriyapada 25 verses : different units of time and a method for determining the positions of planets for a given day, calculations concerning the intercalary month adhikamAsa , kShaya-tithis, and a seven-day week with names for the days of week.

In addition, some versions cite a few colophons added at the end, extolling the virtues of the work, etc.

## Reward Yourself

It is highly likely that the study of the Aryabhatiya was meant to be accompanied by the teachings of a well-versed tutor. While some of the verses have a logical flow, some do not, and its unintuitive structure can make it difficult for a casual reader to follow.

Indian mathematical works often use word numerals before Aryabhata, but the Aryabhatiya is the oldest extant Indian work with alphabet numerals. That is, he used letters of the alphabet to form number-words, with consonants giving digits and vowels denoting place value.

I see nothing suspicious in the discrepancy as Kaye does. Other stanzas are clearly referred to but without direct quotations.

The second section in 33 stanzas deals with mathematics. These three sections contain exactly stanzas.

No stanza from the section on mathematics has been quoted or criticized by Brahmagupta, but it is hazardous to deduce from that, as Kaye does, [4] that this section on mathematics is spurious and is a much later addition. This seems to be most unlikely.

It is, of course, possible that at a later period some few stanzas may have been changed in wording or even supplanted by other stanzas. Such criticism would not arise in regard to mathematical matters which had nothing to do with theological tradition.

The silence of Brahmagupta here may merely indicate that he found nothing to criticize or thought criticism unnecessary. It seems probable to me that Brahmagupta had before him these two stanzas in their present form. It must be left to the mathematicians to decide which of the two rules is earlier.

Later writers attack him bitterly on this point. Even most of his own followers, notably Lalla, refused to follow him in this matter and reverted to the common Indian tradition.In addition, some versions cite a few colophons added at the end, extolling the virtues of the work, etc.
