The mathematical symbol Pi represents the universal constant 3.1415926535... which is the ratio of a circle's circumference to its diameter. Pi is a transcendental number, that is, it cannot be obtained as the solution of any polynomial equation with rational coefficients. This also means that there are infinite digits in Pi, with no apparent pattern:). One of the most beautiful numbers in mathematics, Pi has always fascinated mathematicians and laypeople of all ages. Currently, Pi haw been calculated to 1.24 trillion decimal places with the aid of a supercomputer:D:D.
Now a Japanese mental health counsellor has broken the world record for reciting pi from memory. Akira Haraguchi, 59, managed to recite the number's first 83,431 decimal places, almost doubling the previous record held by another Japanese:)).

Pi (Courtesy: BBC)Mr Haraguchi, from Chiba, east of Tokyo, took several hours reciting the numbers, finishing in the early hours of Saturday. He hopes to be listed in the Guinness Book of World Records to replace his fellow countryman Hiroyuki Goto, who managed to recite 42,195 numbers as a 21-year-old student in 1995. Mr Haraguchi's effort took eight hours and 40 minutes, during which nothing passed his lips except water and several bite-size rice balls:):).
