Japanese man calculates Pi to record-breaking 5 trillion digits!
September 1st, 2010 - 12:53 pm ICT by ANILondon, Sept 1 (ANI): In an astounding and record-breaking mathematical feat, a Japanese man has calculated the value of pi to 5 trillion decimal points using a home made computer.
Shigeru Kondo, a 55-year-old systems engineer, calculated the ratio of the circumference of a circle to its diameter - usually abbreviated to 3.14 - in 90 days and seven hours, reports The Telegraph.
The whole project nearly came crashing down when his daughter tripped a circuit breaker when she turned a hair dryer on. The project was saved when the computer switched to an emergency 10-minute back-up power source.
Kondo was also forced to remove casings from the computer and blow cool air onto the machine with fans as the temperature in his home rose to 40 degrees in the hottest Japanese summer since 1946.
Kondo’s computer costs 11,550 pounds and has a hard-drive capacity of 32 terabytes. Now, he intends to try to compute the value of Pi to 10 trillion digits, saying that he only used an estimated 60 percent of the machine’s capacity. (ANI)
