"Christmas, Easter, Mother's Day, Father's Day, all these celebrations are fine but what about us geeks? Don't we deserve a day where we can do our own thing and celebrate?\r\n\r\nWell if you didn't know it, this day exists! In a few days it's \u03C0 (Pi) Day! Appropriately celebrated on the 14th March (i.e. 3/14/2012), this is the time of the year that we can show off our geekiness and celebrate our love for math and science.\r\n\r\n\u03C0 day is a secular holiday that lets us commemorate the mathematical constant\u00A0\u03C0 (pi). As you know\u00A0\u03C0 is the ratio of a circle's circumference to its diameter (i.e. \u03C0=C/d) and is approximately equal to 3.14159. The Greek letter \u03C0\u00A0is used because it's the first letter of the word\u00A0\u03C0\u03B5\u03C1\u03AF\u03BC\u03B5\u03C4\u03C1\u03BF\u03C2 (perimeter in Greek) and thankfully for the day's celebrations it is pronounced like the word &amp;quot;pie&amp;quot;, making pie the perfect food for the day.\r\n\r\n\r\n\r\n\u03C0 is fascinating because of its importance in so many scientific calculations and because it's an irrational number, meaning that its value cannot be expressed exactly as a fraction having integers in both the numerator and denominator. As a result its decimal representation never ends and never repeats. A lot of effort has been put into calculating it and the latest record is at 5 trillion decimal places. Due to the simplicity of its definition,\u00A0\u03C0 is the most recognised mathematical concept and has a strong position in popular culture.\r\n\r\nHow you celebrate Pi\u00A0Day\u00A0is entirely up to you. Here is my plan for the day and some ideas of what you can do.\r\nMy Celebratory \u03C0 Schedule\r\n\r\n\tWake up - What a beautiful \u03C0 Day\r\n\tMake \u03C0(Pi)ancakes, hopefully in the shape of \u03C0 (now where did I put my tools so I can make a Pi cutter)\r\n\tGet some work done (a geek has to work...)\r\n\tGet \u03C0 (pie) for lunch\r\n\tShoot celebratory pictures wearing a bunny-suit for my blog\r\n\tMeet with geeky friends and eat more pie (the sweet kind)\r\n\tListen to some\u00A0\u03C0-inspired music\r\n\tGet some pizza pie and prepare to watch a movie\r\n\tWatch the best movie for this occasion,\u00A0\u03C0 by Daren Aronowski\r\n\r\nEnough about \u03C0 and me.\u00A0Here are some ideas of what you can do to celebrate Pi Day.\r\nGet your baking caps on\r\n[caption id=&amp;quot;attachment_346034&amp;quot; align=&amp;quot;aligncenter&amp;quot; width=&amp;quot;520&amp;quot; caption=&amp;quot;So many (Pi)es!&amp;quot;][/caption]\r\n\r\nThis day just cries for baking. Because of \u03C0's pronunciation as pie, what else can you do but bake some pies?\r\nI've searched long and hard and the best recipes I've found are:\r\n\r\n\tA pie that has pi's within the pie!\r\n\tAn Archimedes Pi\r\n\tA Key Lime Pi\r\n\tMini Apple Pi Pies\r\n\tSome more Pi Pie recipes\r\n\r\nOf course baking doesn't have to stop with pies. Anything you can bake can be turned into a celebratory creation by shaping it into a Pi (cookies anyone?) and don't forget about pizzas! You can also go the simple route of consuming foods that start with Pi like pineapple and pine nuts.\r\nListen to some music\r\nPi has inspired some people to even write songs about it. Here's the top 3:\r\n\r\n\tKate Bush - Pi (wait until 1:48 when the digits begin)\r\n\tMathematical Pi\r\n\tLucy Kaplansky - Song About Pi\r\n\r\nGet your techy geek on\r\nThe Raspberry Pi is a well anticipated little computer. Head over to element14, enter their competition about what you would do if you had one and you might be the winner, which of course will be announced on Pi Day!\r\nMake a crop circle\r\n[caption id=&amp;quot;attachment_346041&amp;quot; align=&amp;quot;aligncenter&amp;quot; width=&amp;quot;520&amp;quot; caption=&amp;quot;Pi Crop Circle&amp;quot;][/caption]\r\n\r\n&amp;amp;nbsp;\r\n\r\nBack in 2008 someone created this amazing crop circle. At first people were baffled with the meaning of it, then a retired astrophysicist named Mike Reed found that it's a representation of the first ten digits of Pi. If you want to read the full story of how Pi is represented, read this article.\r\nCalculate Pi by throwing frozen Hot Dogs\r\nCalculating Pi is easy (just divide a circle's circumference with its diameter) but there are also experimental ways to calculate it. The most fun is the one detailed in this wikiHow article, using frozen hot dogs.\r\nJoin one of these events\r\nPi Day was created back in 1988 by Larry Shaw at the San Francisco Exploratorium. Staff of the Exploratorium and the public would gather for the event, march around one of it circular spaces and then consume fruit pies. Since then, more people have started celebrating Pi Day and hosting events and challenges. Here are some ideas:\r\n\r\n\tThe San Francisco Exploratorium continues to hold Pi Day events every year. Join them this year so you can meet Larry Shaw in person, sing a birthday song to Albert Einstein and have a piece of pie.\r\n\tIf you are around Princeton, then join them for their annual celebration. Events include a tour of the Einstein Exhibit and a movie showing of Ball of Fire.\r\n\tCan't find a local event? That's what online challenges are for. First is the Pi Day Challenge, a series of logic-based puzzles starting on March 14th. Second is the Pi Day Baking Challenge, brought to you by Serious Eats and Instructables\u00A0with a chance to win an iPad!\r\n\r\nJust a few days to get ready for one of the best celebration of the year. How are you celebrating? Let us know in the comments."^^<http://www.w3.org/2001/XMLSchema#string>
