Brahmagupta Biography

Brahmagupta was an Indian astronomer and mathematician. He was the head of the astronomical observatory at Ujjain his probable birthplace.

His main, but not sole, achievements in the field of mathematics were the introduction of zero and negative numbers. Brahmagupta wrote two main texts, both of which deal with arithmetic and astronomy. His first work in was Brahmasphuta siddhanta The Opening of the Universeand in he published Khandakhadyaka. Both of these texts are actually written in verse. Mathematically these works include the first known use of negative numbers and a figure for zero as well as a formula for finding the area of a cyclic quadrilateral based on its sides this is now known as Brahmagupta’s formula; it is a modified form of Hero’s formula.


Also in his first book Brahmagupta solved the Biogrsphy remainder theoremwhich looks at simultaneous linear congruences, by a method different to that used by the Chinese. Brahmagupta also proposed several algebraic rules for solving quadratic and simultaneous equations.

Other work by Brahmagupta included arithmetic progression and theorems relating to right braumagupta triangles. The astronomy included in these books deals with planetary movement and eclipses.

Brahmagupta lived in a time when it was thought that the sun and other planets revolved around the earth, but he was still able to give an accurate figure for the length of a year, days 6 hours 5 minutes and 19 seconds which he later revised to days 6 hours 12 minutes and 36 seconds. We now regard the length of a year as being days 5 hours and 48 minutes.

Some of the work of Bhaskarawhich was published some years later, shows little advancement form that produced by Brahmagupta.

It is true to say that Brahmagupta was the leading mathematician of the seventh century and that his work has had a massive influence throughout the centuries. Sometime in the eighth century the work of Brahmagupta was brought to Baghdad biograhpy it was translated into Arabic and then subsequently it was translated into Latin, at which point it spread throughout the western world. Like many Indian mathematicians of this and later periods, Brahmagupta was producing work that was many centuries ahead of the equivalent work being carried out in the western world.
