### The Count From Sesame Street Counts 10,000 Digits of Pi Because This Is the Internet

I have so many questions. #1: What does the Count have against the number 9?

### The “Pi Is Wrong” Movement Thinks Pi Day Is the Columbus Day of Math-Based Holidays

#### But we still get to eat a bunch of pies today, right? RIGHT!?

We know you love Pi Day, Internet. March 14th = 3.14, and it's an excuse to eat pie. Trust us: we're on board, but not everyone is. Some people think pi is "wrong" and that celebrating it is therefore wrong. Some of those people think we should celebrate Tau instead, but then what dessert do we eat on June 28th?

### Bubble Genius Sent Us Some Soap And It Smells Mathmatically Delicious

#### For when showering with regular soap isn't fun enough.

If you're a regular listener to the Geekosystem podcast, you might remember that this week we received a package in the mail from Bubble Genius, a LA-based Vegan soap company that makes geeky products. We think they look and smell pretty awesome, so we wanted to show you what they sent us, because we like soap. And also showing off. It's sort of a perk.

### Pi Day: You’re Doing it Wrong

This is a post for everybody who wants to be the smartypants in their Twitter or Facebook feed. I'm going to go back to researching pie shops in my area because I don't have the energy to bake tonight. Previously in ViHart Videos

### Forget about Pi Day, Have a Happy Tau Day!

#### Consider the Following

ViHart continues her crusade of adorable internet videos espousing the virtues of using Tau as a constant to define and derive the dimensions of a circle rather than Pi, because it just makes things more simple and clear. At least, it seem like it makes it more clear. Well, I suppose either way, it's an excuse to eat twice as much pie as on Pi Day. Previously in ViHart

### 4,000,000 Digits of Pi Represented in a Single Image, Here’s 500,000 of Them

If you're on this site, you already know that Pi is an irrational number that goes on and on forever without repetition. This fascinating property has led many to present the numbers of Pi in different ways, blurring the lines between mathematics and art. The New York design firm TWO-N has presented their own twist on the irrational number, presenting 4,000,000 digits of the number as a single image. What you see above is just a tiny piece of this impressive project.

### For Pi Day: Pi and Pie Videos! (Yay, Homonyms!)

#### Just What You've Always Wanted

Since Pi/e Day comes but once a year, we have one video about pie and two videos about pi! And in two of them, pi/e is wrong. Above, however, pi is Shakespeare. Maybe. ViHart explains math in iambic pentameter. Somebody give this lady some baked goods. After the jump, why pi/e is (still wrong). Cheers!

### In High Stakes Patent Auction, Google Bids Mathematical Constants

The last vestiges of telecommunications company Nortel were sold off in an auction this week, encompassing some 6,000 patents and patent applications for various technologies. Several big name tech companies were involved in the marathon 4-day bidding process, but Google turned some heads with its unusual bidding strategy. They began with an initial \$900 million "stalking horse" bid, which they upped to \$1,902,160,540 and then to \$2,614,972,128 and finally \$3.14159 billion. Normally, bidders opt for rounder numbers, but the mathematically inclined quickly identified a pattern in Google's bids. Their opening shot was Brun's constant, followed by Meissel-Mertens constant, and finally pi. Reuters quotes a source commenting on Google's bidding, saying "either they were supremely confident or they were bored." Sadly, their whimsically mathematical bids weren't enough to carry the day. The final price for the patent materials was \$4.5 billion, purchased by a coalition of companies comprised of Apple, EMC, Ericsson, Microsoft, RIM, and Sony.

### In Celebration Of Tau: A Musical Ode [Video]

In what might be one of the nerdiest debates of all time, mathematicians are divided about the use of Pi (which starts 3.14) over Tau (which starts 6.28) in geometry. The ongoing debate about Pi vs. Tau is colored by the popularity of Pi, which has its own "day" celebrated on 3/14, most often with the consumption of pies. But while Tau might not have any baked goods to offer, today (6/28) is its turn in the spotlight.

Mathematician Michael Hartl, writer of the Tau Manifesto, has created a musical composition based on the digits of Tau to celebrate what makes this number so much better than Pi. According to Hartl's Manifesto, one of the main arguments for why Tau is better than Pi is that Tau is the ration of a circumference to the radius of a circle, and defining circles by their radius is much simpler for equations. Pi is also a 2-factor number, but Tau is based on a single unit, which is three quarters of a turn around a Tau-defined circle or simply three quarters of a Tau radian.

### Two Videos for Music Theory Nerds

#### it's time to play the music

I know you're out there, music theory nerds. In a practice room, or brewing tea, or massaging your violinist's hickey. (YesIwasinamarchingbandforeightyears.) Chances are, if you're also reading this site, you're a geek. If that's the case, it's also not unlikely that you once wrote a song based on π at some point in some class.  This video is for you. And if you'd like a second video about the 50's Progression (I vi IV V), used by Slipknot, Justin Beiber, the Beatles, and Ritchie Valens and Rebecca Black.

### No, Republicans Are Not Trying to Make the Value of Pi “Exactly 3”

One of the most popular articles on The Huffington Post right now is about a Republican Congressional proposal called "HR 205, The Geometric Simplification Act," which aims to make the value of pi "exactly 3." Reading the article carefully, it's pretty clear it's satire: "'It’s no panacea, but this legislation will point us in the right direction. Looking at hard data, we know our children are struggling with a heck of a lot of the math, including the geometry incorporating pi,' Roby said. 'I guarantee you American scores will go up once pi is 3. It will be so much easier.'" And Ron Workman has traced its origin to an ancient Internet rumor that was debunked by Snopes in 1998. (The real HR 205 under consideration by Congress now is actually about Native American tribal land-leasing.) But here's the thing: Thanks to the A.D.D.-enabling power of social media, all it takes is a truncated Facebook headline and excerpt for people to form an opinion about a story, and many of them don't actually read it.

### A Very Convincing Case Against Pi [Video]

#### hold on to your butts

It may be Pi Day, but this brilliant and thoroughly enjoyable girl maintains that π is wrong. Not because of the actual number -- π still equals 3.1415 ... -- but when applied to circle constants (and the equation used to calculate them, C/r, or circumference divided by radius), the more accurate number is actually 2π, or τ. Are you ready for a lesson in radians? How about one with actual pie? Seriously, someone get this girl her own podcast, TV show, anything -- She has made the case for Tau Day! (YouTube)

### Happy Pi Day! (Or Is That Half Tau Day?)

By geek tradition, 3/14 is widely celebrated as Pi Day, because, well 3.14 and all of that. Hardly just the mathematical constant used to define various key properties of circles, pi is symbolic of the enigmatic power of math. The symbol is teasingly simple, yet the number goes on forever; truly, a most poetic idea. And it sounds like "pie," and everybody loves pie. OK, we'll admit it: A big part of Pi Day's appeal is that geeks want to stuff themselves with baked goods, but hey, you deserve it. Here's the thing: Though everyone likes pie, not everyone likes pi. Vi Hart, whose work we've featured in the past, is one such person: In the video above, she allies herself with tau (τ), the mathematical constant defined as 2π. For reasons outlined in the video, Hart and tau proponents (Tauists?) argue that if history and schools had worked together to ensure that tau rather than pi was adopted as the circle constant of choice, math education would be a lot less confusing and many equations would look much more elegant. All fascinating stuff, but if that sounds a little dry, Hart bakes two delicious pies in the video, so we all win. (via TDW)

### Happy Pi Day!

#### Audience Participation

It's Pi day, so appreciate the fearful symmetry of circles, eat some baked dishes consisting of a pastry dough casing that contains a filling of sweet (or savory) ingredients, and appreciate this moment of pure spontaneous genius at this weekend's Paul and Storm set from PAX East 2011. Somewhere in there you might even catch my own soprano arrrrr. Unlikely.
