Aryabhatta is a renowned mathematician and astronomer of ancient India. He was born in 476 AD in Kerala. He studied at the University of Nalanda. One of his major work was Aryabhatiya written in 499 AD. The book dealt with many topics like astronomy, spherical trigonometry, arithmetic, algebra and plane trigonometry. He jotted his inventions in mathematics and astronomy in verse form. The book was translated into Latin in the 13th century. Through the translated Latin version of the Aryabhattiya, the European mathematicians learned how to calculate the areas of triangles, volumes of spheres as well as how to find out the square and cube root.

In the field of astronomy, Aryabhatta was the pioneer to infer that the Earth is spherical and it rotates on its own axis which results in day and night. He even concluded that the moon is dark and shines because of the light of sun. He gave a logical explanation to the theory of solar and lunar eclipses. He declared that eclipses are caused due to the shadows casted by the Earth and the moon. Aryabhatta proposed the geocentric model of the solar system which states that the Earth is in the center of the universe and also laid the foundation for the concept of Gravitation. His propounded methods of astronomical calculations in his Aryabhatta-Siddhatha which was used to make the the Panchanga (Hindu calendar). What Copernicus and Galileo propounded was suggested by Aryabhatta nearly 1500 years ago.

Aryabhatta's contribution in mathematics is unparalleled. He suggested formula to calculate the areas of a triangle and a circle, which were correct. The Gupta ruler, Buddhagupta, appointed him the Head of the University for his exceptional work. Aryabhatta gave the irrational value of pi. He deduced ? = 62832/20000 = 3.1416 claiming, that it was an approximation. He was the first mathematician to give the 'table of the sines', which is in the form of a single rhyming stanza, where each syllable stands for increments at...

...Kopytoff begins his essay voicing support for Appadurai’s unusual methodology that follows things-in-motion, as if they had biographies and social lives as humans do. “In doing the biography of a thing,” Kopytoff counsels, “one would ask questions similar to those one asks about people” (66). He asks:
What, sociologically, are the biographical possibilities inherent in its “status” and in the period and culture, and how are these possibilities realized? Where...

Socrates was born in 470 BC in Circa Athens Greece. His father Sophroniscus was a stone carver and sculpture and his mother was a midwife. He was short and stocky, he had huge eyes and a stubby nose; fortunately he always emphasized the idea that the mind is more important than the looks of the physical body of the thinker. in other words, don't judge a book by its cover. Socrates because was as not a noble did not get a full education, but he did...

Biography - Aryabhata, the Indian mathematician
Aryabhata (476 CE – 550 CE) was the first Hindu mathematician and astronomers from India. He wrote couple of treatise about mathematics and astronomy. Some of them were lost. His most famous works Aryabhatiya completed in 499 CE and the Arya-Siddhanta. Aryabhatiya consists of 108 verses, in which Aryabhata wrote about the mathematics...
