Here's a weird little corner of the internet for you to devour. YouTube user Crysknife007 is well-known for hours-long sci-fi marathons of idling starship engines or the silent ambience of Rick Deckard's apartment. But this time, we get our favorite numbers-addicted Muppet counting Pi up to 10,000 decimal places.
The new Raspberry Pi is smaller, cheaper and more energy efficient—not a bad way to update a best-selling device. Whether you've taken the plunge on one of the new units or you want to put the original model to good use, we've collected together some of the most fun Pi-based projects on the planet for you to have a…
Cristian Ilies Vasile has created the coolest visualization of Pi I've seen. First he divided a circle in 10 segments, from 0 to 9. Then he traced a path going from the third segment to the first segment. From 1, the path jumps to 4, then back to 1, then 5 and so on. After a while, π appears in front of your eyes.…
Recreational mathemusician Victoria Hart—aka Vi Hart—gives overwhelming (and fun!) evidence that clearly demonstrates that Pi is a stupidly common number and the fascination of people with this number is just dumb.
A great deal of time has been spent working out the facts about pi. At one point, the "facts" were wrong. And a mathematician caught the error by using something that, well, might also be wrong.
Martin Krzywinski is an artist. No, wait, he's a mathematician. Actually, scratch that: he's both, and he can make the number Pi look insanely beautiful.
Do you feel like having a once-every-thousand-year party? You only have a couple of years to set it up. Some of us will be planning 2015 Pi Parties — in some cases because we like math, and in other cases because we want an excuse to eat pie for breakfast. Let us know if you're going to be involved.
We may be celebrating Pi Day here at io9, but we would be irrational to deny that there’s more to mathematical interestingness than simply dividing an object’s circumference by its diameter. Here are seven numbers we love as much as pi.
When an amateur mathematician from Indiana managed to solve one of mathematics' great problems—squaring the circle—he decided to copyright his proof, but allow his home state to use it for free. Sadly, things didn't quite go to plan.
Pi is famously calculated to trillions of digits—but how many of them do we really, really need? This video demonstrates that, actually, just 39 will do.
How many numbers of Pi can you rattle off? Probably not many. Probably even fewer if you're drunk. But you can at least cheat with these glasses from TheUncommonGreen that are printed with hundreds and hundreds of digits from the mathematical constant.
Any eyes in San Francisco that weren't focused on Apple's announcements yesterday might have noticed something peculiar in the skies over the Bay area. As part of the ZERO1 Biennial—a months long festival celebrating the coming together of art and technology—an artist known only as Ishky used several planes to…
Pi is what's known as an irrational number, which means that its decimal representation is both infinite and non-repeating.
Pro-tip on pi-tips: this will come off as even more clever if you actually ordered pie. Or a pi pie.
It's Pi Day! Which, okay, whatever, if you were really hardcore about celebrating you'd figure out what nanosecond corresponds to 3.14159 or whatever and pop the Moet then but you didn't and you won't so whatever, right? But! That doesn't mean we can't still have some fun with the nerdiest holiday in the land,…
There's an old urban legend about a state legislature that passed a law redefining pi so that it equaled 3. This story is a myth - but the true story that inspired it is actually even more ridiculous and bizarre.
