Pi with Pies (director's slice) - Numberphile

A 6'28" version of our "Pi with Pies" calculation. More links & stuff in full description below ↓↓↓ Videos features Matt Parker who tweets at https://twitter.com/standupmaths The Pi-inspired music in the video explained: http://periodicvideos.blogspot.co.uk/2013/03/pimusic.html Our full collection of Pi videos at http://bit.ly/W4oDN1 While the pies are usually delicious, this batch was not for consumption (even by hungry students, for those who suggested it!) but we feel they were used in a fun way to make people think about mathematics - perhaps some people who would not otherwise take an interest... To mark Pi Day we instead donated £314 to a local charity which helps feed people in crisis. If you'd like to make a donation, here are some suggestions: Matt is a supporter of Depaul UK, helping young homless people. You can donate through their website: http://www.depauluk.org/ Numberphile's donation was to a local group which does not have online donation facilities. However here are some other options... http://www.wfp.org/ http://www.foodcycle.org.uk/ http://www.napsoc.org/ Contact us with any others you'd like on the list! Numberphile also raises money for cancer research if you'd prefer - donate here: http://www.justgiving.com/numberphile-charity Special thanks to Pukka Pies (for the pies), Notts Country FC (for hosting us) and the football channel Copa90 (for helping us out) - http://www.youtube.com/user/Copa90football - plus James Hennessy for being second camera!
