Pi -An irrational Number

Hey....You remember school mathematics???

Area of Circle = p r²    where  p =22/7 .
 Is it the true value of p ?
Actually it is the fraction whose value is very close to p which is equal to 3.14159.......................................
Now where does this end?Don't know. p is a very special number. Its decimal expansion has neither repeating pattern nor terminating decimal representation.
Thus, p is an irrational number and very special. So far scientists have discovered 10,000 digits after the decimal point for which a special computer is required to store such big number.
There are many applications of this special number p.
It is used in the construction of Pyramids.I have read somewhere that there is a shloka in Bhagvadgita, which on decoding gives the value of p upto 32 decimal places. This tells us how ancient is p andit was used in India long ago.
p has always fascinated me !!!
I hope you are also little bit motivated to discover more about p......
