π (Pi), how could we live without it. So let’s celebrate π on it’s day 3.14.

As you remember from grammar school math, π is the mathematical constant consisting of the main numbers 3, 1 and 4. According to the Wikipedia of π, “it is the the ratio of a circle’s circumference to its diameter, and is approximately equal to 3.14159.”

It has been represented by the Greek letter “π” since the mid-18th century, though it is also sometimes written as pi. π is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers (such as 22/7 or other fractions that are commonly used to approximate π); consequently, its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed, although no proof of this has yet been discovered. π is a transcendental number – a number that is not the root of any nonzero polynomial having rational coefficients. The transcendence of π implies that it is impossible to solve the ancient challenge of squaring the circle with a compass and straight-edge.

OK, enough of that. Let’s get on to the party part

It’s earliest known celebration was in California where in 1988 at the San Francisco Exploratorium physicist Larry Shaw along with the staff and the public marched around one of its circular spaces eating fruit pies. In 2009. The US House of Representatives passed a non-binding resolution declaring 3.14 π (Pi) Day.

Coincidentally, it is also the birthday of theoretical physicist Albert Einstein. So at Princeton University in New Jersey there are numerous celebrations around both events that also include an Albert Einstein look alike contest.

Besides the partying at Princeton, here’s what is going on elsewhere to celebrate this mathematical necessity that drives mathematicians nuts.

In the past, MIT has posted its acceptance letters to high school seniors on Pi Day.

   Attention, Chicago residents: First Slice Pie Café will be giving out free slices of pizza today at 3:14 pm. For readers in the Southeast, pizzas cost $3.14 at Your Pie’s 16 locations across Georgia, Tennessee and Florida.

   The Microsoft store is offering 3.14% off on Dell tablets.

   At Mission High School in California’s Bay Area, students are composing “piems” – poems that have “the same number of letters as the corresponding digit of pi.”

   It’s OK if all of this talk about pi is making you crave pie. Last night, students at Cal Tech hosted a late-night pi-themed pie-eating party. The Pasadena Sun reports: students “dug into 130 pies laid out for them outside student housing. There were 26 each of five different pies. Follow that? So on 3/14 at 1:59 a.m. there were 26 each of five kinds of pie. None is by chance. The first digits of Pi are 3.14159265.”

   After pigging out on pies, you can go on a 3.14 mile bicycle ride in Milwaukee.

   And by the way, if you think all this pie-eating on Pi Day is merely an exercise in bad puns, prepare to have your mind blown.

   In France, British writer Daniel Tammet has kicked off “France’s first Pi Day celebration” at the Palace of Discovery, Paris’s science museum, CNN reports. In 2004, the then-25-year-old recited “22,514 digits of pi from memory” – breaking the European record.

And the founder of π Day, retired physicist Larry Shaw will be at the Exploratorium today leading a “Pi Procession”, in which “Pi partiers will get a yardstick mounted to a pie plate, each with a single digit of pi on it. Then all 500 of them will line up in pi-order” and trot around the “Pi Shrine.”

In 2010’s “Moment of Geek”, Rachel Maddow, host of MSNBC’s “The Rachel Maddow Show,” featured a math student teacher, Teresa Miller, from the University of New Mexico with a hula hoop and a Rubic’s Cube that was quite amazing.

I was never that energetic as a math student. Teresa should be a great math and phys ed teacher.

So, whatever you do today, every time you see a circle or a pie of any kind remember π

March 14 is the 73rd day of the year (74th in leap years) in the Gregorian calendar. There are 292 days remaining until the end of the year.

On this day in 1885, The Mikado a light opera by W.S. Gilbert and Arthur Sullivan, had its first public performance in London.

The Mikado, or, The Town of Titipu is a comic opera in two acts, with music by Arthur Sullivan and libretto by W. S. Gilbert, their ninth of fourteen operatic collaborations. It opened in London, where it ran at the Savoy Theatre for 672 performances, which was the second longest run for any work of musical theatre and one of the longest runs of any theatre piece up to that time. Before the end of 1885, it was estimated that, in Europe and America, at least 150 companies were producing the opera. The Mikado remains the most frequently performed Savoy Opera, and it is especially popular with amateur and school productions. The work has been translated into numerous languages and is one of the most frequently played musical theatre pieces in history.

Setting the opera in Japan, an exotic locale far away from Britain, allowed Gilbert to satirise British politics and institutions more freely by disguising them as Japanese. Gilbert used foreign or fictional locales in several operas, including The Mikado, Princess Ida, The Gondoliers, Utopia, Limited and The Grand Duke, to soften the impact of his pointed satire of British institutions.

The Mikado is a comedy that deals with themes of death and cruelty. This works only because Gilbert treats these themes as trivial, even lighthearted issues. For instance, in Pish-Tush’s song “Our great Mikado, virtuous man”, he sings: “The youth who winked a roving eye/ Or breathed a non-connubial sigh/ Was thereupon condemned to die / He usually objected.” The term for this rhetorical technique is meiosis, a drastic understatement of the situation. Other examples of this are when self-decapitation is described as “an extremely difficult, not to say dangerous, thing to attempt”, and also as merely “awkward”. When a discussion occurs of Nanki-Poo’s life being “cut short in a month”, the tone remains comic and only mock-melancholy. Burial alive is described as “a stuffy death”. Finally, execution by boiling oil or by melted lead is described by the Mikado as a “humorous but lingering” punishment.

Death is treated as a businesslike event in Gilbert’s Topsy-Turvy world. Pooh-Bah calls Ko-Ko, the Lord High Executioner, an “industrious mechanic”. Ko-Ko also treats his bloody office as a profession, saying, “I can’t consent to embark on a professional operation unless I see my way to a successful result.” Of course, joking about death does not originate with The Mikado. The plot conceit that Nanki-Poo may marry Yum-Yum if he agrees to die at the end of the month was used in A Wife for a Month, a 17th century play by John Fletcher. Ko-Ko’s final speech affirms that death has been, throughout the opera, a fiction, a matter of words that can be dispelled with a phrase or two: being dead and being “as good as dead” are equated. In a review of the original production of The Mikado, after praising the show generally, the critic noted that the show’s humour nevertheless depends on

“unsparing exposure of human weaknesses and follies-things grave and even horrible invested with a ridiculous aspect-all the motives prompting our actions traced back to inexhaustible sources of selfishness and cowardice…. Decapitation, disembowelment, immersion in boiling oil or molten lead are the eventualities upon which (the characters’) attention (and that of the audience) is kept fixed with gruesome persistence…. (Gilbert) has unquestionably succeeded in imbuing society with his own quaint, scornful, inverted philosophy; and has thereby established a solid claim to rank amongst the foremost of those latter-day Englishmen who have exercised a distinct psychical influence upon their contemporaries.”

The Freedom of the Press Foundation Press, an organization “dedicated to press freedom and transparency in a digital age,” released an audio recording of Pvt. Bradley Manning reading a statement he made in military court at Fort Meade on February 28 about releasing United States government documents to WikiLeaks. Glenn Greenwald, one of the founders of FPF, had this to say at The Guardian about the audio tape:

The court-martial proceeding of Bradley Manning has, rather ironically, been shrouded in extreme secrecy, often exceeding even that which prevails at Guantanamo military commissions. This secrecy prompted the Center for Constitutional Rights to commence formal legal action on behalf of several journalists and activists, including myself, to compel greater transparency. One particularly oppressive rule governing the Manning trial has barred not only all video or audio recordings of the proceedings, but also any photographs being taken of Manning or even transcripts made of what is said in court. Combined with the prohibition on all press interviews with him, this extraordinary secrecy regime has meant that, in the two-and-a-half years since his arrest, the world has been prevented, literally, from hearing Manning’s voice. That changes today.

The Freedom of the Press Foundation (FPF), the group I recently helped found and on whose board I sit, has received a full, unedited audio recording of the one-hour statement Manning made in court two weeks ago, and this morning has published that recording in full.

The Guardian published the full text of the statement as it was transcribed bu independent journalist Alexa O’Brian who has been covering the pre-trial hearings. Here also is the unclassified redacted statement in a pdf file.

Daniel Ellsbreg, who leaked the Pentagon Papers to the New York Times, joined Amy Goodman on Democracy Now to discuss the audio of the statement:

“What we’ve heard are people like The New York Times who have consistently slandered him … that he was vague and couldn’t think of specific instances that had led him to inform the American people of injustices,” Ellsberg says. “The American people can now, for the first time, hear Bradley in his own words, emotionally and in the greatest specific detail, tell what it was that he felt that needed revelation.”

A Salute to Bradley Manning, Whistleblower, As We Hear His Words for the First Time

by Daniel Ellsberg

Today, the Freedom of the Press Foundation, an organization that I co-founded and of which I’m on the board, has published an audio recording of Bradley Manning’s speech to a military court from two weeks ago, in which he gives his reasons and motivations behind leaking over 700,000 government documents to WikiLeaks.

Whoever made this recording, and I don’t know who the person is, has done the American public a great service. This marks the first time the American public can hear Bradley Manning, in his own voice explain what he did and how he did it.

After listening to this recording and reading his testimony, I believe Bradley Manning is the personification of the word whistleblower. [..]

For the third straight year, Manning has been nominated for the Noble Peace Prize by, among others, Tunisian parliamentarians. Given the role the WikiLeaks cables played in the Arab Spring, and their role in speeding up the end of the Iraq War, I can think of no one more deserving who is deserving of the peace prize.

I see a hero in these wars whose example should inspire others. His name Bradley Manning.
