ARYABHATT (476 CE)
MASTER ASTRONOMER AND MATHEMATICIAN
Born in 476 CE in Kusumpur ( Bihar ), Aryabhatt's
intellectual brilliance remapped the boundaries of mathematics and
astronomy. In 499 CE, at the age of 23, he wrote a text on astronomy and
an unparallel treatise on mathematics called "Aryabhatiyam." He
formulated the process of calculating the motion of planets and the time
of eclipses. Aryabhatt was the first to proclaim that the earth is
round, it rotates on its axis, orbits the sun and is suspended in space -
1000 years before Copernicus published his heliocentric theory. He is
also acknowledged for calculating p (Pi) to four decimal places: 3.1416
and the sine table in trigonometry. Centuries later, in 825 CE, the Arab
mathematician, Mohammed Ibna Musa credited the value of Pi to the
Indians, "This value has been given by the Hindus." And above all, his
most spectacular contribution was the concept of zero without which
modern computer technology would have been non-existent. Aryabhatt was a
colossus in the field of mathematics.
