Buffalo Bills Going the Moneyball Route With Analytics 94

Nerval's Lobster writes "Can data-analytics software win a Super Bowl? That's what the Buffalo Bills are betting on: the NFL team will create an analytics department to crunch player data, building on a model already well established in professional baseball and basketball. 'We are going to create and establish a very robust football analytics operation that we layer into our entire operation moving forward,' Buffalo Bills president Russ Brandon recently told The Buffalo News. 'That's something that's very important to me and the future of the franchise.' The increased use of analytics in other sports, he added, led him to make the decision: 'We've seen it in the NBA. We've seen it more in baseball. It's starting to spruce its head a little bit in football, and I feel we're missing the target if we don't invest in that area of our operation, and we will.'"

Ramanujan's Deathbed Conjecture Finally Proven 186

jomama717 writes "Another chapter in the fascinating life of Srinivasa Ramanujan appears to be complete: 'While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right. "We've solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years," Emory University mathematician Ken Ono said. Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said.'"

Ask Slashdot: Android Apps For Kids Under 12 Months? 311

An anonymous reader writes "My kid seems incredibly interested in my Android tablet, but I'm not too comfortable with letting her play with my browser. I've been hunting the app store for apps that I could let my kid play around with, but haven't found much. It seems like most apps are targeted for slightly older kids and are trying to teach them words, math or whatnot. Has anyone found any cool apps for approximately 6-month-old children? I'm mostly looking for something that makes funny noises or where you just have to e.g. track moving objects on the screen."

Juggling By the Numbers 59

theodp writes "The BBC News' Laura Gray reports on a juggling notation system developed in the 80's called Siteswap (aka Quantum Juggling and Cambridge Notation) and how it has helped jugglers discover and share thousands of new tricks. Frustrated that there was no way to write down juggling moves, mathematician Colin Wright and others helped devised Siteswap, which uses sequences of numbers to encode the number of beats of each throw, which is related to their height and the hand to which the throw is made. 'Siteswap has allowed jugglers to share tricks with each other without having to meet in person or film themselves,' says James Grime, juggling enthusiast and math instructor for Cambridge University. Still unclear on the concept? Spend some time playing around with Paul Klimek's most-excellent Quantum Juggling simulator, and you too can be a Flying Karamazov Brother!"

TI-84+C-Silver Edition: That C Stands For Color 198

skade88 writes "Do you remember those large TI-8X line of calculators with a BW display from when you were growing up and learning all about math? Yeah well, you can still get them because TI has yet to update or change their line of TI-8X calculators from their 96x64 display, processors designed in the 1980s with just a few kilobytes of user accessible memory. They still cost in the $100.00 to $150.00 range. That is all about to change now that the TI-8X line of calculators is 22 years old. Their new TI-84+C-Silver edition will come with a 320x240 16-bit color display, 3.5MB of flash ROM, and 21KB of RAM. Ars has a good preview of the device along with speculation on why it took so so so very long for TI to finally bring calculators up to a level of technology that could have been delivered a decade ago."Last month some photos and a few details of the new TI-84+C were leaked.

Ask Slashdot: Replacing a TI-84 With Software On a Linux Box? 254

yanom writes "I'm currently a high school student using my TI-84 for mathematics courses. It has all the functionality I need (except CAS), but saying that the hardware is dated is putting it nicely. Waiting 4-5 seconds for a simple function to be graphed on its 96x64 screen just makes me want to hurl it at the wall. Recently, I've begun to notice the absurdity of doing my math homework on a 70's era microchip when I have an i7 machine with Linux within arm's reach. I've begun looking for software packages that could potentially replace the graphing calculator's functionality, including Xcas and Maxima, but both lack what I consider basic calculator functionality — xcas can't create a table of values for a function, and maxima can't use degrees, only radians. So, does anyone know of a good software package to replace my graphing calculator (and maybe provide CAS to boot)?"

If Tech Is So Important, Why Are IT Wages Flat? 660

dcblogs writes "Despite the fact that technology plays an increasingly important role in the economy, IT wages remain persistently flat. This may be tech's inconvenient truth. In 2000, the average hourly wage was $37.27 in computer and math occupations for workers with at least a bachelor's degree. In 2011, it was $39.24, adjusted for inflation, according to a new report by the Economic Policy Institute. That translates to an average wage increase of less than a half percent a year. In real terms, IT wages overall have gone up by $1.97 an hour in just over 10 years, according to the EPI. Data from professional staffing firm Yoh shows wages in decline. In its latest measure for week 12 of 2012, the hourly wages were $31.45 and in 2010, for the same week, at $31.78. The worker who earned $31.78 in 2010 would need to make $33.71 today to stay even with inflation. Wages vary by skill and this data is broad. The unemployment rate for tech has been in the 3-4% range, but EPI says full employment has been historically around 2%."

One Cool Day Job: Building Algorithms For Elevators 203

McGruber writes "The Wall Street Journal has an article about Theresa Christy, a mathematician who develops algorithms for Otis Elevator Company, the world's largest manufacturer and maintainer of people-moving products including elevators, escalators and moving walkways. As an Otis research fellow, Ms. Christy writes strings of code that allow elevators to do essentially the greatest good for the most people — including the building's owner, who has to allocate considerable space for the concrete shafts that house the cars. Her work often involves watching computer simulation programs that replay elevator decision-making. 'I feel like I get paid to play videogames. I watch the simulation, and I see what happens, and I try to improve the score I am getting,' she says."

Statistics Key To Success In Run-and-Gun Basketball 97

theodp writes "Two decades before Moneyball hit the Big Screen, Coach David Arseneault of tiny Grinnell College came up with a unique style of run-and-gun basketball that he called The System, the principles of which were subjected to statistical analysis in Keys to Success in a Run-and-Gun Basketball System, a paper for the 2011 Joint Statistical Meetings. Well, as they say, sometimes The System works. On Tuesday, biochem major Jack Taylor, just three games into his career as a Grinnell College basketball player, made national news when he poured in 138 points — yes, 138 points — in a 179-104 victory over Faith Baptist Bible College. Even LeBron and Kobe were impressed. The old NCAA Division III record of 89 was set last year by Taylor's Grinnell teammate, Griffin Lentsch. Taylor's feat also bested what was deemed to be the unbeatable overall NCAA scoring record of 113 points, set by NCAA Division II performer Clarence 'Bevo' Francis of Rio Grande in 1954."

Linux On the TI-Nspire Graphing Calculator 49

An anonymous reader writes "Developers been working hard for the past few months to get Linux ported to the TI-Nspire calculator. The port is not yet fully stabilized nor quite ready for broad consumption and requires some user-level knowledge of Linux systems, but is definitely worth a try. Experimental support for root filesystem installed on USB mass storage is being worked on, so that Datalight's proprietary Flash FX/Reliance filesystem used by TI's OS isn't a limit anymore. This also means that the native TI-Nspire OS image is not replaced by the Linux system, and Linux can been booted on demand. Support for USB keyboard, X server, directFB, Wi-Fi (with the help of a powered USB hub) and text-based Internet browsing is progressively being added and tested."

Climate Treaty Negotiators Are Taking the Wrong Approach, Say Game Theorists 227

An anonymous reader writes "Climate treaty negotiators would do well to have a little chat with some game theorists, according to this article. The fundamental approach they've been taking for the last several years is flawed, these researchers say, and they can prove it. From the article: 'The scientists gave members of a 10-member group their country’s “treasure”: a 20-euro national savings account, plus a fund for spending on emissions reductions that consisted of 10 black chips worth 10 cents apiece and 10 red chips worth one euro apiece. Each person could then contribute any number of these chips to a common pool. The contributed chips represented greenhouse gas reduction strategies that were relatively inexpensive (black) or expensive (red). Players could communicate freely about their plans for how many chips they intended to contribute.'"

Nate Silver Turns His Eye To the American League 50

Lasrick writes "Nate Silver is at it again. This time, instead of the presidential election, he's focusing on the baseball's Most Valuable Player race for the American league. It's a race that embodies the split among baseball fans between those who think of it from a mathematical perspective (the Moneyball generation) and those who prefer the traditional, feel-of-the-game perspective. Here's a quote: 'On Thursday, the American League will announce the recipient of its Most Valuable Player award. The winner is likely to be Miguel Cabrera, the Detroit Tigers star who won the league’s triple crown by leading in batting average (.330), home runs (44) and runs batted in (139). It might seem as if these statistics make Cabrera, the first triple crown winner in either league since 1967, a shoo-in for the M.V.P. But most statistically minded fans would prefer that it go to another player, Mike Trout of the Los Angeles Angels.'"

Fabricating Nature and a Physical Turing Test 36

Nwe submitter arrow3D writes "A new startup in Norway is focused on design and fabrication at the level and quality of nature. Using pure mathematical volumes, rather than surfaces or voxels, they are developing a new generation of 3D modelling tools specifically aimed at high resolution 3D printing, to 'support the future of design and manufacturing.' Their software was recently used to create the multi-material Minotaur Helmet by Neri Oxman from MIT, as featured in Wired UK last month. An interesting thought (as recently illustrated in Dilbert) is the idea of a Physical Turing Test for synthetic objects and that both Turing Tests may require each other — i.e. only by designing and building at the resolution of nature can we achieve the intelligence of natural objects. Their software platform is still very much under development but they've started trying to 'save the world from polygons' with a KickStarter campaign that's live now."

With NCLB Waiver, Virginia Sorts Kids' Scores By Race 622

According to a story at Northwest Public Radio, the state of Virginia's board of education has decided to institute different passing scores for standardized tests, based on the racial and cultural background of the students taking the test. Apparently the state has chosen to divide its student population into broad categories of black, white, Hispanic, and Asian — which takes painting with a rather broad brush, to put it mildly. From the article (there's an audio version linked as well): "As part of Virginia's waiver to opt out of mandates set out in the No Child Left Behind law, the state has created a controversial new set of education goals that are higher for white and Asian kids than for blacks, Latinos and students with disabilities. ... Here's what the Virginia state board of education actually did. It looked at students' test scores in reading and math and then proposed new passing rates. In math it set an acceptable passing rate at 82 percent for Asian students, 68 percent for whites, 52 percent for Latinos, 45 percent for blacks and 33 percent for kids with disabilities." (If officially determined group membership determines passing scores, why stop there?) Florida passed a similar measure last month.

Evidence for Unconscious Math, Language Processing Abilities 168

the_newsbeagle writes "It's hard to determine what the unconscious brain is doing since, after all, we're not aware of it. But in a neat set of experiments, researchers from the Hebrew University of Jerusalem's consciousness lab found evidence that the unconscious brain can parse language and perform simple arithmetic. The researchers flashed colorful patterns at test subjects that took up all their attention and allowed for the subliminal presentation of sentences or equations. In the language processing experiment, researchers found that subjects became consciously aware of a sentence sooner if it was jarring and nonsensical (like, for example, the sentence 'I ironed coffee')."

Tuition Should Be Lower For Science Majors, Says Florida Task Force 457

Hugh Pickens writes "Jordan Weissmann writes that a task force commissioned by Florida Governor Rick Scott is putting the finishing touches on a proposal that would allow the state's public universities to charge lower tuition for studying topics thought to be in high demand among Florida employers including science, technology, engineering, and math. The hope is that by keeping certain degrees cheaper than others, Florida can encourage students into fields where it needs more talent. For some, it might seem inherently unfair to send dance majors deeper into debt just to keep tuition low for engineers, who are already poised to earn more once they graduate, but task force chair Dale Brill says tax dollars are scarce, and the public deserves the best possible return from its investment in education and that means spending more generously on the students who are most likely to help grow Florida's economy once they graduate. Brill also argues that too few young people consider their career prospects carefully when picking a major. 'We're trying to introduce some semblance of a market dynamic information in an environment where there is none,' Brill says. 'Most students couldn't tell you what they pay in tuition. In economics, pricing is all we have to determine and work out supply and demand. So, when the consumer is completely separated from the cost of a product, then the cost rises.'" Remember when everyone was supposed to become an aerospace engineer and then the industry collapsed in the early 90s?

Physicist Explains Cthulhu's "Non-Euclidean Geometry" 179

An anonymous reader writes "Mathematician Benjamin K. Tippett has written a fascinating and deadpan paper (Pdf) giving insights into Cthulhu. A 'Bubble' of warped Space-Time makes alarmingly consistent sense of the dead God's cyclopean city under the sea. From the paper: 'We calculate the type of matter which would be required to generate such exotic spacetime curvature. Unfortunately, we determine that the required matter is quite unphysical, and possess a nature which is entirely alien to all of the experiences of human science. Indeed, any civilization with mastery over such matter would be able to construct warp drives, cloaking devices, and other exotic geometries required to conveniently travel through the cosmos.'"
