Happy Pi Day everyone! Wait, what?
Ah. Missed it. Well, sort of. You see, we were all ready for some Pi Day Magic this year. We’ve made an iPhone app (and we hope it will be available for other smartphones soon), but it was not approved in time. I win!… at failing.
But it’s available to download now at http://app.pidaymagic.com (and it’s free)
It’s a mathematical magic trick where your volunteer may choose any five cards from a deck. One card is then hidden, yet you can determine the volunteer’s hidden card from the other four. Are people really so predictable?
Download the app now to find out how to perform this trick. Plus, all will be revealed in a future episode of Scam School with Brian Brushwood.
And for those of you who like puppets, here is my little promo/advert
Finally, after a long wait, we reveal the Pi Day Magic in what I’m calling Pi Day Magic + 1.92
Click here to read the reveal article by me (James Grime) for more on the Magic and Mathematics of this trick. Or click the video below to see how it’s done on this special episode Scam School with Brian Brushwood. You can still play along on Twitter, and now you can perform it for yourself on your friends!
Yesterday was the start of our Pi Day Magic!
We’ve had a thousand participants so far from all over the world – despite the Twitter-Crash which lasted about 7 hours right in the middle of the event. I have aged 20 years in the last 24hours!
Amazingly ‘Happy Pi Day’ was a trending topic worldwide. You geeky people.
And you can still play! We’re busy people, we can’t reply to you all individually, but we’ve written a script that will reply and tell you the number of which you were thinking – it’s that clever. To play just follow the instructions here on the website, and send your digits using the hashtag #pidaymagic as before. We will keep it running all week.
And check back at pidaymagic.com tomorrow when we will reveal how we did it, and you will be able to perform this trick yourselves on your family and friends. We will release an episode of Scam School explaining how you can pull this trick off, as well as an article by myself explaining the magic and the mathematics of the Pi Day Magic event.
Thanks go out to my partner in this event Brian Brushwood (@shwood), as well as massive thanks to Brian Pollock (@cloudoidltd) – whose idea this was, and Dave Wagner (@kaeladan) – codemonkey, master of the Dave Fu.
Special thanks to Simon Singh (@SLSingh), Marcus du Sautoy (@marcusdusautoy), Richard Wiseman (@richardwiseman), the Times Higher Education Supplement (@Timeshighered) , Mismag822 (youtube/mismag822), Cambridge Science Festival (@camscience) and to everyone who retweeted and spread the word about Pi Day Magic yesterday!

Our first promo, just a quick video by me with the first details
For one day only, one mathematician and one magician will join forces to perform what we believe will be the world’s largest live online magic trick, and you can join in!
Sunday the 14th of March 2010 will be World Pi Day (03.14), and to celebrate we will be performing a very special mathematical magic trick live on Twitter.
This event will form part of the Cambridge Science Festival, running from the 8th to the 21st of March (http://www.cambridgescience.org). Dr James Grime (@jamesgrime) is a mathematician currently working for the Millennium Mathematics Project at Cambridge University (http://mmp.maths.org), and Brian Brushwood (@shwood) is an award-winning magician and host of popular internet series “Scam School” (http://scamschool.tv).
For more details on how to join in on the day, check pidaymagic.com for instructions, or follow the event using the hashtag #pidaymagic. And, no matter where you are in the world, we will read your mind.
We think this will be a record-breaking event and we want you to get involved and be part of history! And remember to check back after the event as we reveal how it was done in a special episode of Scam School.
Keep checking pidaymagic.com or follow the hashtag #pidaymagic. Tell your friends and watch as the magic unfolds.
