Slashdot Mirror

"Three-point-one-four was more than a number to museum curator Larry Shaw," writes the San Francisco Chronicle. Long-time Slashdot reader linuxwrangler writes: In 1988 at a retreat for San Francisco Exploratorium staff, Larry Shaw proposed linking the digits of pi, which begins 3.14, with the date March 14. Initially the "holiday" was only celebrated by museum staff but it didn't take long for the idea to spread and Pi Day was born.

For 38 years, Mr. Shaw donned a red cap emblazoned with the magic digits and led a parade of museum goers, each of them holding a sign bearing one of the digits of pi. Shaw died August 19 at age 78 and a memorial is planned for Sunday September 24.
The memorial will be held in Mill Valley, California, the Chronicle reports, adding that "pie will be served."

mikejuk writes to let us know that today is Pi Day — 3/14 in American date notation. He writes, "This year, it feels as though we aren't celebrating alone. For the first time, it looks as if momentum has built up to the point where people have heard about Pi Day. There are even attempts to sell you Pi-related items as if it was a real holiday. But there is always some one to spoil the party so what ever you do to celebrate don't miss Vi Hart's Anti-Pi Rant video." Thus begins the yearly debate over Pi Day vs. Tau Day (June 28). Phil Plait has a post defending Pi Day's honor, and MIT isn't holding back their Pi Day celebrations. Large-scale celebration of Pi Day began in 1988, mostly through the efforts of physicists Larry Shaw and Ron Hipschmann at the San Francisco Exploratorium. The Exploratorium still runs Pi Day events 26 years later, including Pi-themed processions and pie for dessert. In 2009, Pi Day became semi-official through a vote by the House of Representatives. (They did a better job with Pi than did Indiana, who almost legislated it to be 3.2.)

The best way to celebrate Pi Day is to get together with some friends and talk math over a pie. You could even go for a pizza pie, since a pizza with radius 'z' and height 'a' has volume = pi * z * z * a. If you'd care for a game, head over to the Pi Day Challenge, which features a series of pi-related logic puzzles. Or just spend the day learning about pi.

Cool pi facts: Pi is currently known to about 10 billion decimal places. You can calculate pi using the Fibonacci sequence. A few years ago, Steven Rochen mapped the digits of pi to musical notes and turned it into a violin solo (video). Others have made music from pi as well. Mankind didn't know the first hundred digits of pi until the year 1701. How many digits of pi can you recite? The record for memorization currently stands at 67890 digits. The record for reciting pi while juggling three balls is just under 10,000.

New submitter SchrodingerZ writes "'The world's most precise measurement of the mass of the W Boson, one of nature's elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory.' This new number (80387 +- 17 MeV/c^2) puts more constraint on the mass of the theorized Higgs Boson, which is theorized to give mass to all other things, supporting the standard model. 'Scientists employ two techniques to find the hiding place of the Higgs particle: the direct production of Higgs particles and precision measurements of other particles and forces that could be influenced by the existence of a Higgs particle.'"

Even if the microbial science doesn't interest you, the scenery really is something to behold."

Slashback tonight brings some clarifications, and updates to previous Slashdot stories including: a victory for evolution in Kansas, the Stardust Program launched, Lego Mindstorms goes live, continued backlash on the new E3, Archimedes gets a webcast, another Dell bursts into flame, and a possible RIAA silver bullet Read on for details.

A Victory for Evolution in Kansas. SatanicPuppy writes "Yesterday, elections in Kansas saw four of six pro-Creationism school board members replaced by pro-Evolution candidates in a one issue election. Interestingly, it didn't go by party lines; at least one of the conservative Republicans who supported Creationism failed to make it past their party primary. Ken Willard and John Bacon are the two remaining pro-Creationism incumbents."

Stardust Program Launched. lee1 writes "Anyone with an internet connection now has the the chance to find microscopic grains of dust from beyond the solar system. The project, called Stardust@home, is patterned on projects like SETI@home. But rather than exploiting idle processor time, it will ask volunteers to search through millions of microscope images on their computer screens, exploiting spare time in general as well as ego: 'People get very competitive,' explains the project director. The first volunteer to spot an actual interstellar dust grain will get to name it and will be listed as a co-author on any resulting research papers. The images come from a NASA project called Stardust, whose primary mission was to collect samples of dust from the tail of Comet Wild 2, but might also have captured some interstellar dust that could reveal the physics of the stars that produced it. To minimize false positives and to ensure that all the grains are found, each participant will go through an online training and testing process before starting their search. They will be scored on how well they distinguish real dust grain impacts from fakes."

Lego Mindstorms goes live. MicroBerto writes "As of August 1, 2006, the next generation of Lego Mindstorms is now available for sale in North America. Mindstorms NXT is a robotics toolset that allows you to build and program robots for various purposes. It combines the power of the Lego technic building system and an all new intuitive software environment powered by National Instruments LabVIEW."

Continued backlash on the new E3. Anonymous Howard writes "Angry Gamer reacts badly to the news of the Electronic Entertainment Expo's demise. They see it as a major blow for small game developers who are having enough of a hard time getting noticed by press and retailers as it is. From the article: 'This is a win only for the EAs, Sonys and IGNs of the world. Everyone else has to fend for themselves.' It seems like the days of smaller developers getting noticed by 'drive by traffic' at E3 are over." Relatedly The Escapist Lounge has an interview with the Academy of Interactive Arts and Sciences president, Joseph Olin, on what is actually happening to E3. As Joseph Olin responds: 'So it's going to take a couple of months until the world knows what the scope of E3 2007 will be, and how it will be structured. The opportunity to make material changes to improve it shouldn't be snap judgments. The rhetorical question I might pose is: "You know you have a problem. You know you need to make changes. How do you make changes and convey it and announce it, and to whom, and when?" There's never a good time. Whenever you make significant change, there's no way to introduce that change without detractors. The challenge is that without being able to announce the exact implementation of change it leaves that gray area for ignorance to fill the void.'"

Archimedes gets a webcast. jd writes "Some time ago, Slashdot covered the story of the rediscovery of several lost writings of Archimedes by means of X-Ray fluorescence. Well, they're still scanning the book and at 11pm GMT (4pm PDT) on August 4th will be putting on a live webcast as they scan and interpret pages not seen by human eyes for over a thousand years."

Another Dell bursts into flame. starwindsurfer writes "A Dell laptop's battery caught on fire in a company's IT department this week, burning a hole right through the casing. Nearby techs used fire extinguishers to put out the blaze. Employee Henrik took pictures to document the affair and uploaded them to the Toms Hardware message boards. From the writeup: 'The police department showed up. The entire lower floor was allowed to leave early and as we stood there in front of the building we simply couldn't resist... we jokingly called the engineer a terrorist as he was being asked a few questions by the friendly officer.'"

An RIAA silver bullet? Chris Fairman writes "TechDirt is running a story about how the RIAA seems to be dropping cases where the defense includes (or hinges on) an IP address as the means to identify the source of criminal activity. Essentially the defense argues that all an IP address can prove is who was paying for the net access at a particular time. Having a wide open WiFi router on your network seems to be currently the most effective means of getting the RIAA to drop all charges. Essentially the activity originating from one IP, only proves that illegal file sharing behavior is coming from one network, and not necessarily from any one specific computer or user. More importantly, it seems that the legal system is beginning to catch on to more complex technology concepts. Such concepts play a large part in how future legal cases are argued, and contribute ultimately to the foundation of complex technology legal precedents."

QuantumFTL writes "According to an MSNBC story Opportunity, the same rover that scored an interplanetary hole-in-one, has broken free of an interplanetary sand trap. The MER science operations mailing list was abuzz this morning with the news, as soon as the first rear hazcam image indicating success came down. Engineers were praised for working long nights and weekends to make this extrication possible. Good job, NASA!"

beatleadam writes "After seeing Randy Johnson of the Arizona Diamondbacks pitch a perfect game (coverage here), I searched Slashdot in the hopes of reading more about what the Slashdot readers thought of this feat of athleticism and science and to learn more about the physics of baseball (More information to be found here and here). As nothing was posted, I submit for your viewing pleasure a "course" in the Physics of Baseball and the subtle science that is pitching."

ajayg writes: "This looks cool. A science museum called Exploratorium will be hosting live webcasts featuring the Hubble Telescope by giving a virtual tour of Space Telescope Science Institute,Goddard Space Flight Center in Maryland, and the Exploratorium in San Francisco. There are 5 different shows to be be telecast on the 19th, 20th, 21st, 22nd and the 24th. It should be an interesting insight into the most influential space telescope of all time. Check it out here."
