Nevermind the Pi music, here's what Tau sounds like (video)
There's a heated debate going on in the exciting world of mathematics that pits notoriously irrational pi against relative newcomer tau. Wherever side of the fence your math club's allegiance may lie, a quick listen to Michael Blake's newest nerd composition could have your circle singing a different equation. Perhaps spurred by the copyright brouhaha that yanked his earlier musical extrapolation -- What Pi Sounds Like -- from the YouTubes, Blake set this interpretation of the controversial constant to 126 decimal places and let'er rip at 125.6 bpm. What follows is a not-unpleasant symphony that should have Bjork's producers calling for a collaboration. Full video for the prog-rock nation after the break.
Robots master delicate art of juggling, prep for clown college (video)
Not to be outdone by their flying cousins, some less mobile bots are taking on the challenge of juggling. After the break you'll find a pair of vids, including one featuring a creation from the Czech Technical Institute in Prague that can launch five balls between its two "hands" with the aide of a high-speed tracking camera. The other clip stars the "Blind Juggler," a somewhat more impressive machine that has no sensors or cameras. Instead, it relies on mechanical feedback and some fancy math to control the trajectory of the ball and keep it airborne. The Blind Juggler debuted back in 2009, but creators Philipp Reist and Raffaello D'Andrea introduced an interesting wrinkle for version 2.0 by turning the entire thing into a pendulum that passes the ball to itself. Clearly, the next step is face paint and red, foam noses -- bringing our most bed-wetting of night terrors to life.
Supercomputer cracks sixty-trillionth binary digit of Pi-squared, gets beaten up by normal computers
Pencils down, everyone. IBM's "BlueGene/P" supercomputer has beaten you to the sixty-trillionth binary digit of Pi-squared after only a few months -- at one quadrillion calculations per second. Running thousands of independent processors, the number-crunching monster accomplished what would have taken a single CPU 1,500 years. A cloud-computing effort last year calculated Pi itself out to the two-quadrillionth digit, but you may wonder why this all matters. "What is interesting in these computations is that until just a few years ago, it was widely believed that such mathematical objects were forever beyond the reach of human reasoning or machine computation," said one researcher, "Once again we see the utter futility in placing limits on human ingenuity and technology." So there's that. But in all the commotion no one seems to have announced whether the landmark digit was a one or a zero: all you betting on the outcome will have to dig deeper into the source link.
Kokuyo's X-VIZ designer calculator is tailor-made for one-armed accountants
We're not exactly sure why anyone would ever want a designer calculator, but for those who do, Kokuyo's got you covered. The Japanese company has just announced the X-VIZ -- a super slim, matte-finished device that can help you balance your checkbook with one hand. Crafted by robot designer Tatsuya Matsui, the X-VIZ probably isn't something you'd use to carry out heavy duty operations and, at just 12mm thick, it certainly won't double as a mouse, either. But at least Kokuyo refrained from tacking on another superfluous laser or detachable holster, as it's been known to do. Both black and white models of the X-VIZ will hit the Japanese market on May 11 for ¥5,250 ($64), so hit up your favorite importer if you're interested in grabbing one.
TERA releases Community Play Event numbers
If you're a TERA fan but not lucky enough to score an invite to En Masse Entertainment's recent Community Play Event (CPE), you can take heart in the fact that the company has released some information pertaining to all the players who did attend. We know, there's the potential for some salt in the wound here, but En Masse's Jon Tuite nonetheless has some interesting factoids relating to character races, classes, leveling trends, and many other data points. It seems that Castanics were the most popular race during the recent CPE, and humanoid races in general accounted for a whopping 68% of all characters. Tuite also points out that the Baraka race was the least popular (7% of the population) and postulates that the lack of a female version could be the culprit. In terms of class and party dynamics, the CPE data aren't far removed from your average fantasy MMO (i.e., there were a plethora of DPS types, fewer tanks, and even fewer healers). These stats are the tip of the proverbial iceberg, and you can indulge in more number-crunching at the official TERA website.
It's Pi Day. Do you know what 3.1415926535897932384626433832795 sounds like?
It may not be marked on most calendars, but if you're a math nerd (or a nerd in general -- of which we count ourselves, obviously), you know what March 14th is. It's 3/14, otherwise known as the first three digits of Pi. That's since become a minor geek holiday of sorts, and has prompted some fairly unique celebrations over the years. One of the latest comes from musician Michael John Blake, who interpreted Pi to the first 31 decimal places as musical notes and turned it into a song -- played at 157 beats per minute, no less (or half of 314). As it turns out, however, Blake wasn't the first to come up with the idea -- composer Lars Erickson wrote his own "Pi Symphony" a few years back, and has now sparked a bit of a copyright spat on YouTube over who actually owns the rights to Pi in musical form. Head on past the break to check out both versions for yourself.
TI-Nspire graphing calcs get full color displays, 3D, WiFi, and new OS
It's been a good year or so since the TI-Nspire line of graphing calculators got a refresh, but that was nothing compared to what the company's planning for this year. Possibly responding to changing times (or the Casio Prizm), the new Nspire devices are getting a WiFi dongle for communication with TI-Navigator workstations, a 16-bit (320 x 240) full color display, and a number of new functions, including the ability to load images and analyze images for such things as curve fitting functions and regressions. Perhaps even more exciting, the new Nspire OS 3.0 features 3D functions -- and, yes, the original grayscale TI-Nspire models will be able to upgrade to the new OS when it becomes available this spring. Tech Powered Math is reporting a mid-April release date, for an MSRP of $165. Totally psyched? We bet you are! See the PR after the break for more info.
DARPA's MSEE to develop new mathematical language, race of sentient machines
The hyper-ambitious folks at DARPA are totally over the current state of military data collection, and they're pretty sure they know how to fix it: teach sensors how to think. Well, they've got an idea how to fix it, but they've put out a call for mathematician to do the dirty work. The Mathematics of Sensing, Exploitation, and Execution (MSEE) program seeks a unified mathematical language that cane teach sensors not only to collect data, but to interpret, and act on it too. The aim is to eliminate the "data deluge" that comes from ever-increasing streams of information, like cellphone intercepts and video drone feeds, allowing analysts to focus on the important stuff. Currently the onus falls on humans to interpret the overwhelming amount of information collected by military sensors, but DARPA is confident that the right algorithm could have machines interpreting the world as early as 2014. Which gives you right around three years to fulfill every fantasy you've ever had.
Google hides mathematical puzzle in Cr-48 video, rewards its solver with a laptop
Watching Google destroy Cr-48 laptops for fun can't have been easy for any of you, but it turns out that the wily geeks of Mountain View had a clandestine purpose to their malevolence after all. An equation, scribbled out in old school chalk in the background of one scene, attracted the attention of a Sylvain Zimmer, who, together with a group of like-minded geeks, set about trying to solve it and discover its meaning. A full day's worth of cryptographic work later, Sylvain was left with a set of numbers he was able to convert into letters, which in turned spelled out "speed and destroy." Appending goo.gl, Google's URL shortener, to the front of those words got him to a screen congratulating him for being "first to figure out our MENSA-certified puzzle" and promising to send him a Cr-48 laptop as his prize. Kudos to Sylvain... and to Google for being such irrepressible geeks.
Oxford neuroscientists shock the parietal lobe, improve math scores
We always knew that the willy-nilly application of electricity (or, for that matter, radiation) endowed the person on the receiving end with super powers, but neuroscientists at Oxford have taken our misguided notion one step further. The researchers were looking into dyscalculia, a rare impairment related to dyslexia that creates an innate difficulty in understanding mathematics, when they came up with an idea that, to us, seems totally obvious: a very low level (one thousandth of an amp) electrical stimulus across the parietal lobe. So far, the study has been limited to fifteen right-handed students but the results have been pretty interesting. When the current flowed from the right to the left, subjects' ability to solve various mathematical puzzles were improved -- for up to six months after the treatment. However, if the electricity was sent the other way, the effect was reversed and the volunteers' scores were on par with a six year old. "Much more research is needed before we can even start thinking of this kind of electrical stimulation as a treatment," said Oxford's Dr. Cohen Kadosh. "However, we are extremely excited by the potential of our findings and are now looking into the underlying brain changes."
Yahoo! researcher breaks Pi record in finding the two-quadrillionth digit
A new record has been broken in the field of mathematics by a team of researchers and a super computer working on creating a very long version of Pi. The team, led by Nicholas Sze of Yahoo!, used the company's Hadoop cloud computing tech to break the previous record by more than double, creating the longest Pi yet. Back in January, the record was set at 2.7 trillion digits using a standard, full mathematical calculation of the problem, but the Hadoop route was different. It set different parts of the computer to work on different sections of the problem, cutting up the problem into manageable-sized pieces (as shown in the formula in the image above). We're sure this record won't survive long enough for anyone to write a song about it, but it's quite an achievement all the same.
Futurama writer devises (and proves) math theorem to save The Professor's and Amy's mind
Sure, you could prove as-of-yet-unsolved mathematical problems (why hello there, P≠NP), but where's the entertainment value for the rest of us? Cue Futurama staff writer Ken Keeler, who used his PhD in "Math Blasters (in N Dimensions)" to create and verify a theorem that served as the crux of the plot for the recent Prisoner of Benda episode, wherein minds and bodies can only be switched in one direction and order must eventually be restored. Thus we are at a crossroads, dear reader: you can either brush up on your Group Theory and related permutations and expressions... or alternatively, just take a chill and enjoy a hilarious moment in science fiction. Next up, let's explore the ramifications of Heisenberg's Uncertainty Principle being disproven when a peanut butter sandwich fell into the large hadron collider, and by some stroke of luck scientists were able to simultaneously determine its momentum, position, and crunchiness.
HP labs researcher thinks he might have proof of P≠NP, has another Millennium problem been solved?
If you don't know the major problems facing mathematics and computer science, you might not be familiar with the problem of P versus NP. In short, it's a problem which asks, "if 'yes' answers to a yes or no question can be quickly verified, can they also be computed quickly?" Many computer scientists have long suspected that P≠NP, and it's been listed by The Clay Mathematics Institute as one of the Millennium Problems (another of which was solved earlier this year), carrying a 1 million dollar prize if solved. Apparently, HP researcher Vinay Deolalikar has been working on the problem in his spare time, and it seems that he's emailed his preliminary paper in support of P≠NP to the committee tasked with judging the Millennium Prize. His HP profile says he's received several preliminary confirmations of his draft, and that a final paper is currently in preparation. We wish him luck, and we'll keep you updated.
DIYer constructs 4.3-inch Open SciCal graphing calculator, puts your TI-83+ to shame
What's 4.3-inches diagonally, costs $200 to build and has absolutely no reception issues when held as shown in the image above? Why, the Open SciCal! Matt Stack, the genius who pieced this gem together, relied on a 1GHz ARM Cortex A8 CPU, 8GB SD card, WiFi module and a spartan web browser in order to concoct what's likely the most desirable graphing calculator this side of Pluto. The handheld device weighs about 1.6 pounds, runs Linux as well as the statistically inclined R, and is reportedly capable of doing roughly twice as much crunching as Texas Instruments' Nspire. Skeptical? Considering that this bad boy sucked down stock data from Yahoo! Finance and ran auto-correlation on the numbers in order to near-instantly report current trends, we're guessing TI (or any other graphing calculator company, really) has no room to argue. Hit the source for more details, and don't worry -- that feeling of insignificance wanes with time.
Reclusive mathematician says 'thanks, but no thanks' to that million dollar prize
Russian mathematician Grigori Perelman has apparently turned down a one million-dollar prize which he was awarded in March by the Clay Mathematics Institute. Perelman was awarded one of seven million dollar prizes for solving a "millennium" problem -- the Poincaire conjecture -- which had been puzzling mathematicians for about one hundred years. The problem -- which was a theorem about the governing the properties of three-dimensional spheres -- was one of the most important questions in topology before being solved. While this is not the first time he's turned down a prize, Perelman has seemingly rejected this one because he disagrees with the "organized mathematical community."
Namco Bandai helping to create textbooks with RPG elements
We spent a remarkable amount of our formative years doodling video game characters into the margins of our textbooks, so we appreciate Namco Bandai's initiative to cut out the middle man. According to Andriasang, the developer recently partnered with publisher Gakko Tosho to create elementary school textbooks which feature persistent storylines and other RPG elements. For instance, a "Math Adventure" book has student solving arithmetic puzzles to gain keys, which can be used to earn some form of treasure. It's certainly an interesting take on the concept of educational gaming -- and, based on our elementary school Writing class journal, which is literally filled, cover to cover, with Pokémon illustrations and fan fiction, we imagine it'll gain some traction with Japan's young people.
TUAW's Daily App: John Enock's Quaso
We've been spotlighting a lot of quick and easy action games in our Daily App feature lately, so here's something a little more cerebral. Quaso is a new kind of Crossword-style puzzle game, except that instead of guessing words, you're trying to figure out numbers in math equations. The game was created by an English mathematics teacher named John Enock, and has been brought to the iPhone by a developer as John Enock's Quaso, now available on the App Store for free. Here's how it works. For every crossword line on the board, you're given a set of math equations with the numbers missing. There's one total number for every puzzle (say, 6), and then for each equation, you need to figure out how another set of numbers fits in to complete the clue and make the equation equal to the total number. In other words, given the clue (*+*) x (*-*), and the answer of 6, you'd eventually work out that the numbers should be (1+2) x (5-3), and then put 1, 2, 5, and 3 in each spot on the answer. But that answer line has to match up to any that it intersects with, so you may need to switch the numbers around -- (2+1) instead of (1+2) -- for it all to work. It's fiendishly clever, and it really puts your brain to work, especially if (like me) you're not that great at casual math. But there are a ton of puzzles to work through, and then you can even buy a puzzle pack via in-app purchase for more. Especially at the current price of free, Quaso is a mathematical brain teaser that you shouldn't miss.
TI-Nspire graphing calculator gets a new touchpad, nerds swoon world o'er
Texas Instruments has been making graphing calculators for twenty years now, and things look pretty much the same as they were in that bygone era of Amy Grant and C&C Music Factory. The company's latest, TI-Nspire with Touchpad, features -- you guessed it! -- a touchpad above the keypad for scrollin' around, as well as a letterpad (apparently they had to forgo QWERTY to make this compliant with tests like SAT and ACT). And, like its precursors, it comes with a snap-in TI-84 Plus keypad so your old dog won't have to learn any keystrokes. Available now from your fave e-tailer, look to pay around $140.
The Daily Grind: What still doesn't make sense to you?
We've got a pretty complicated hobby here, even by the frequently vexing standards of general gaming enthusiasts. There are more than a few elements that we have to wrap our heads around in order to play effectively, much less be on the forward edge. So it's kind of inevitable that we each find our own breaking point for where we stop understanding why we need to do some things. The whole series of explanations eventually turns into an endless rant that looks similar to English but just doesn't make sense. You might have read all of the math for the defense cap in City of Heroes or the diminishing returns mechanic in Star Trek Online, but you might not have understood the numbers being flung around. Or perhaps it's something even simpler, like the very concept of the soft cap for Hit in World of Warcraft. Not for lack of trying, your brain just won't process it. So what still doesn't make sense to you despite your best efforts? Is it a small aspect of gameplay or something you urgently feel the need to get right? Has it made a major impact on your playstyle?
Twist alarm clock has you wring math equations by the neck
Man has striven for centuries to build a better mousetrap, but in the digital age, mice are the least of our worries. No, the modern day rat race requires a better alarm clock instead, and lord knows we've seen plenty, from tickers that chomp your change to clocks that give you target practice. What we don't see that often is a clock that makes you think at the same time it provokes a physical action. Thus, the Twist Alarm Clock, which displays a simple math equation when it's time to wake up, but requires effort to silence. In order to quiet the alarm, you have to twist the numbered dials on either side of its LCD screen into the right position -- in this case, to figure out what minus what equals two. It's no Turing Alarm Clock, to be sure, but this human number cruncher's actually for sale; you can get yours for ¥2,625 (about $28) in Japan.
