## The Cranberries to Release Final Album With Dolores O’Riordan, Commemorate Debut Anniversary With Reissue

The late Dolores O’Riordan recorded tracks for one final album with the Cranberries before her passing, and now the new material will see the light of day “early next year,” according to the band. Three days before her death, O’Riordan spoke with guitarist Noel Hogan about their upcoming studio album, an album that would have been The Cranberries’ first in six years, and emailed him a number of new tracks. The band revealed in a statement today that a new album had been in the works since last year, with vocals already recorded by O’Riordan.

March 14 is Pi Day — that’s pi, not pie — and today, Google marks the 30th anniversary of the math-inspired holiday with a special Doodle.

Pi, denoted by the Greek letter “?”, has been part of human knowledge for millennia, but it wasn’t until 1988 that physicist Larry Shaw organized what is now recognized as the first “Pi Day” celebration at the San Francisco Exploratorium science museum. Shaw chose March 14, or 3.14 — the first three digits of pi — as the holiday. Shaw died last year, but his brainchild is still celebrated by lovers of mathematics around the world.

Pi represents the ratio of a circle’s circumference to its diameter. It’s an important part of the foundation of mathematics, most importantly geometry, where it is key to equations calculating the area of a circle, A = ?r2, and the volume of a cylinder, V = ?r2h.

Japanese marked the seventh anniversary Sunday of a tsunami that took more than 18,000 lives on the northeast coast and triggered a nuclear disaster that turned nearby communities into ghost towns.

Various ancient civilizations calculated approximations of pi, including the Egyptians, Babylonians, and there’s even a reference to the dimensions of a circle in the Bible, but the first calculation of pi as 3.14 is attributed to Greek mathematician Archimedes, who lived in the third century B.C.. It was also independently determined by Chinese mathematician Zu Chongzhi (429–501), who computed pi to six decimal places. Mathematicians adopted the symbol ? for the expression in the 18th century: Welsh mathematics teacher William Jones is often credited with the first use of the symbol in 1706.

Pi is a mathematical constant, meaning it isn’t changed by the size of the numbers it’s used to equate, and it is irrational, meaning it has an infinite number of digits that never repeat. The rise of computing technology has led to an arms race of sorts to calculate ever more digits of pi: the current record was set last year by Christian physicist Peter Trueb, calculated pi to 22.4 trillion digits — 22,459,157,718,361, to be exact — outpacing the previous record set in 2013 by 9 million digits.

But adding new digits is little more than a pastime for mathematics fanatics: NASA’s Jet Propulsion lab only uses 15 digits to calculate interplanetary travel, while mathematician James Grime argues that just 39 digits of pi is enough to calculate the circumference of the known universe.

Pi Day was officially recognized by Congress in 2009, and it’s inspired quirky and pun-filled celebrations, including eating circular treats, from fruit pies to pizza, as well as dressing like Albert Einstein, whose birthday serendipitously falls on the math-imbued day. San Francisco’s Exploratorium also hosts an annual day of pi-inspired activities. The Massachusetts Institute of Technology releases its undergraduate admissions decisions on Pi Day, and starting in 2012, it began sending the verdicts at 6:28 pm, or “Tau time,” for the mathematical equation 2?. This year, NASA is inviting math whizzes to compete in its “Pi in the Sky” challenge to solve a series of interplanetary math problems.

## Ms. Lauryn Hill To Headline Pitchfork Festival With 'Miseducation' Anniversary Set

The full lineup for Pitchfork Festival is here, and it boasts a very special set from Ms. Lauryn Hill in its Sunday headlining slot. Joining Tame Impala as a previously announced headliner are Fleet Foxes and Hill, whose performance will celebrate the 20th anniversary of her pivotal album, The Miseducation of Lauryn Hill. Miseducation went on to collect a number of awards and accolades following its 1998 release: It spent four weeks at No. 1 on the Billboard 200, and took home five Grammy Awards, including the historic distinction of being the first-ever hip-hop release to earn the Album of the Year honor.
