Abstract

The universal real constant pi, the ratio of the circumference of any circle and its diameter, has no exact numerical representation in a finite number of digits in any number/radix system. It has conjured up tremendous interest in mathematicians and non-mathematicians alike, who spent countless hours over millennia to explore its beauty and varied applications in science and engineering. The article attempts to record the pi exploration over centuries including its successive computation to ever increasing number of digits and its remarkable usages, the list of which is not yet closed.

All circles have the same shape, and traditionally represent the infinite, immeasurable and even spiritual world. Some circles may be large and some small, but their ‘circleness’, their perfect roundness, is immediately evident. Mathemat

The number is the ratio of the circumference of a circle to its diameter. This ratio is the same for all circles and cannot be expressed exactly as a decimal. A practical approximate value for that is often used is 3.1416 or 3 . Apart from circles, also appears in problems related to certain surface areas and volumes in solid geometry. However, the use of is not restricted to geometry alone; many branches of mathematics and physics, such as number theory, statistics, acturial theory, vibrational theory and alternating electric currents, engage the number .

The use of the numbergoes as far back as around 2000 B.C. The Egyptians used the value of 3.16 in some of their calculations. However the concept of among the Egyptians was rather vague. In the Old Babylonian period (c. 1800 - 1600 B.C.) the circumference of a circle was found by taking three times its diameter. This gave a value of 3. The Hebrews, according to biblical accounts used the same value.

It was the Greeks who showed concerted interest in determining the val
