How was the Gupta Empire (India) scientifically advanced? Describes scientific achievements of the time.

When thinking back to the Gupta Empire in India, one might remember the famous works of literature, or perhaps the vast lands conquered by the great rulers of the time. But it would be imprudent to ignore the influential achievements made in the areas of science, medicine, mathematics, and astronomy that made the empire scientifically advanced. Many people fail to realize that countless things mistaken for solely modern-day science, for example, plastic surgery, existed centuries ago. Here, the technologies of the Gupta Empire (320-467), such as the development of a more accurate value for pi, the perfection of the modern numeral and decimal system; surgery, inoculation, the formulation of medical guides and a better calendar; and lunar astronomy, will be discussed in detail.

First we will deal with the area of mathematics. One of the most recognized achievements of the Gupta period was the highly accurate calculation of pi, made by the renowned mathematician Aryabhata. Before this time, pi, the value that explained the relationships between the area, circumference, diameter, radius, and volume of circles and spheres, was frequently represented by Indian mathematicians as three, or the square root of ten. (Although both of these values are far from accurate, the fact that the civilization had a knowledge of geometry and mathematical relationships is proof of scientific advancement, especially when one compares it to Europe, which in the eleventh century still had no knowledge of mathematics.) Aryabhata calculated pi to the fourth decimal place at a value of 3.1416. Aryabhata also studied and improved other concepts of mathematics; for example, he determined the rule for the area of isosceles triangles and researched algebraic identities and intermediate equations. His work can be observed in the Gitikapanda, a book which includes a trigonometrical sine table, rules for extracting square and cube roots, the concepts of spheres, pyramids and other plane figures,
