In the pantheon of fictional detectives, Rex Stout's Nero Wolfe is among the best. If you haven't met the fat, cranky, sedentary, orchid-loving gourmand of a detective, and his street-smart, wise-cracking, witty right-hand of an assistant, Archie Goodwin, this introduction to the pair may be of use. Between 1935 to 1974, Wolfe and Goodwin solved mysteries, captured criminals of all ilks, and on one notable occasion, got the upper hand on J. Edgar Hoover. The books are very much of their time.

Ahead of Pi Day (March 14), Matt Parker tries to accurately calculate pi using pies. [SLYT] An extended version of the video will be uploaded on Pi Day, but here's your chance to go out and buy pies before that.

Jason Padgett is the first person to acquire synasthesia and savantism by head trauma. Three years after his mugging, he began drawing complex geometries, including hand-drawn approximations of fractals, the first time anyone had ever done so. Eventually a mathematician suggested Padgett take a math course; with trigonometric notation Padgett offered a proof of his approximation of Pi. [more inside]

Happy Tau Day! τ (2 × π, that is, 6.28...) is the number of radians in a turn. Translating the digits to notes even makes beautiful music. (By comparison, what pi sounds like). Previously.

This is what pi sounds like. At least, that's one person's interpretation. There are certainly plenty of others, including touchtone pi, hammered dulcimer pi, violin pi, smooth techno pi, crazy awesome pi, vaguely unsettling pi (sounds best with headphones), and lots of piano pi. Pi has even done a duet with its buddy *e*. Nothing here that tickles your fancy? Think you could do better? Why not make your own pi song? Hell, make two! If you're having trouble remembering all those pesky digits, don't worry: there's a song for that, too.

"This day may be celebrated in a variety of ways. Pause and give thought to the role that the number pi has played in your life. Imagine a world without pi. Attempt to memorise pi to as many decimal places as you can. If you're feeling creative, devise alternative values for pi. Go to a party (I will). Or just celebrate in the time-honoured fashion of ignoring Pi Approximation Day altogether."

In 1897, the Indiana House of Representatives passed a bill mandating that the ratio of the circumference to the diameter of a circle (pi) was 3.2. Now, 112 years later, their neighbors in the Illinois Senate have passed a resolution redefining Pluto as a planet, at least when it passes through the Illinois night sky. Of course, Pluto may not even travel through the Illinois night sky for some time.

Nowhere-neat tilings are actually pretty neat. We all know you can't "square the circle", but do you know the story of squaring the square? (And by the way, even if you can't construct π with a ruler and compass, you can come awfully close without too much work.)

Celebrate π. Sing about π. Wear π. Learn the digits of π. Watch the wonder of π. Be vexed by the implications of π. Get slightly embarrassed for π. Give all your love to π. **Happy Pi Day. Nerds rule!**

That Kate Bush song where she sings 150 digits of π and gets it wrong [possibly]? Turns out it contains secret references to, among other things, some stones in Cornwall that look sort of like a steam locomotive and a number of megalithic sites. No, seriously. He's got proof.

In case it has escaped your attention, tomorrow is 14 March which, in American notation, is written 3/14. If you have a certain type of mind you will immediately notice that these digits bear a close approximation to one of the most important numbers in mathematics - pi.

If the universe is a hologram and the healthy human brain a valve of consciousness then where'd this mental infinity come from? Are we simply living the simulacrum? Or does Pi protect us all, forever, infinitely?

Very few people will ever need to learn the value of pi beyond a handful of digits, but some people are more obsessed than others. They call themselves Piphilologists, and all the pi-memorization writings you could ever possibly want have been compiled into one massive Piphilogical text file. And today, Piphilologists the world over must surely bow in tribute to Akira Haraguchi, who has just recited pi from memory to 83,431 places.

Is your date of birth in pi? Of course it is, eventually. But are you one of the lucky 63% whose special day falls within the first 100,000,000 digits? How about your Social Security Number? That club is even more exclusive. A good tool for the pi-curious.

You've helped crack mathematical games, you've searched for aliens, the cure for cancer, cure for AIDS and even tried to calculate pi. What's left to do in distributed computing? How about helping the fight against anthrax? Remember, if you don't download the screensaver, the terrorists have won.
