Aaryabhateeya 
Aaryabhateeya Aaryabhat's intellectual brilliance remapped the boundaries of mathematics and astronomy. In 499 AD, at the age of 23, he wrote a text on astronomy and an unparallel treatise on mathematics called "Aaryabhateeyam". In this book he writes that it was written in 3,630 years into the Kali Yug. This correspondences to 499 BC. His work covers Arithmetic, Algebra, plane Trigonometry, and spherical Trigonometry. It also contains continued fractions, quadratic equations, sumsofpower series, and a table of sines. Aaryabhat himself may not have given it this name to his work. This name, "Aaryabhateeya", must have been given by later commentators. His disciple Bhaaskar I calls it Ashmak Tantra (or the treatise from the Ashmak  Ashmak means stone). It is also occasionally referred to as Aarya Shatasht (literally, Aaryabhat's 108), because there are 108 verses in this text. It is written in the very terse style, typical of Sootra literature, in which each line is an aid to memory for a complex system. Thus, the explication of meaning is due to commentators. The text consists of the 108 verses and 13 introductory verses, and is divided into four Paad or chapters: (1) Geetikaa Pad: (13 verses): large units
of time  Kalp, Manvantar, and Yug, which present a cosmology different from earlier
texts such as Lagadh's Vedaang Jyotish
(c. 1st century BC). There is also a table of sines (Jyaa), given in a single verse. The
duration of the planetary revolutions during a MahaaYug is given as 4.32 million years. The Aaryabhateeya presented a number of innovations in mathematics and astronomy in verse form, which were influential for many centuries. The extreme brevity of the text was elaborated in commentaries by his disciple Bhaaskar I (Bhaashya, c. 600 AD) and by Neelakanth Somayaji in his Aaryabhateeya Bhaashya, (1465 AD). He was not only the first to find the radius of the Earth but was the only one in ancient time including the Greeks and the Romans to find the volume of the Earth. (2) Aarya Siddhaant

Other Important Contributions
Aaryabhat 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 AD, the Arab mathematician, Mohammed Ibna Musa credited the value of Pi to the Indians, "This value has been given by the Hindu." And above all, his most spectacular contribution was the concept of Zero, see Shoonya, without which modern computer technology would have been nonexistent. Aaryabhat was a colossus in the field of mathematics.
