<p>Two computer geeks claim to have calculated the number pi to 5 trillion places, on a single desktop and in record time. That's 2.3 trillion digits more than the previous world record held by the Frenchman Fabrice Bellard. Japanese system engineer Shigeru Kondo and American student Alexander Yee achieved the result using a program created by Yee and a desktop computer built by Kondo.<p><a href="https://plus.maths.org/content/computer-geeks-break-pi-record" target="_blank">read more</a></p>https://plus.maths.org/content/computer-geeks-break-pi-record#commentsformula for Piinfinite seriesThu, 05 Aug 2010 16:26:15 +0000mf3445275 at https://plus.maths.org/contentPi not a piece of cake

<p>[maths]Ever since the Egyptians' first attempts to calculate $\pi$ over two millennia ago, the number has been a constant in the minds of mathematicians. Whether calculating it to billions of decimal places, being mystified by its surprising appearance in areas such as statistics and number theory, or deriving new formulae to describe it, they have struggled to understand the nature of the
oldest known "hard" number.<p><a href="https://plus.maths.org/content/pi-not-piece-cake" target="_blank">read more</a></p>https://plus.maths.org/content/pi-not-piece-cake#commentsformula for Pinormal numberPiSat, 31 Aug 2002 23:00:00 +0000plusadmin2744 at https://plus.maths.org/content
