The Mathematical Case For Buying a Powerball Ticket 480

HughPickens.com writes Neil Irwin writes at the NYT that financially literate people like to complain that buying lottery tickets is among the silliest decisions a person could make but there are a couple of dimensions that these tut-tutted warnings miss, perhaps fueled by a class divide between those who commonly buy lottery tickets and those who choose to throw away money on other things like expensive wine or mansions. According to Irwin, as long as you think about the purchase of lottery tickets the right way — purely a consumption good, not an investment — it can be a completely rational decision. "Fantasizing about what you would do if you suddenly encountered great wealth is fun, and it is more fun if there some chance, however minuscule, that it could happen," says Irwin. "The $2 price for a ticket is a relatively small one to pay for the enjoyment of thinking through how you might organize your life differently if you had all those millions."

Right now the Multi-State Lottery Association estimates the chances of winning the grand prize at about 1 in 175 million, and the cash value of the prize at $337.8 million. The simplest math points to that $2 ticket having an expected value of about $1.93 so while you are still throwing away money when buying a lottery ticket, you are throwing away less in strictly economic terms when you buy into an unusually large Powerball jackpot. "I am the type of financial decision-maker who tracks bond and currency markets and builds elaborate spreadsheets to simulate outcomes of various retirement savings strategies," says Irwin. "I can easily afford to spend a few dollars on a Powerball ticket. Time to head to the convenience store and do just that."

Inside the Internet's Hidden Science Factory 31

tcd004 writes Sarah Marshall has completed roughly 20,000 academic surveys. Clay Hamilton has finished about 40,000. Marshall and Hamilton are part of a small but highly-active community of paid online study participants on Amazon's Mechanical Turk who generate data at break-neck speed to fuel modern scientific research. But can a person who's completed thousands of surveys still provide good data? Here's a look at the humans feeding science from inside the machine.

Feeling Upset? Look At Some Meat 155

Meshach writes "A study out of Canada claims that seeing meat actually calms a person down. From the article: 'Contrary to expectations, a McGill University researcher has discovered that seeing meat makes people significantly less aggressive. Frank Kachanoff, who studies evolution at the university’s department of psychology, had initially thought the presence of meat would provoke bloodlust, believing the response would have helped our primate ancestors hunt. But in fact, his research showed the reverse is true.'" I can see all the "Make Steak, Not War!" protest signs already.

Why NASA's New Video Game Misses the Point 205

longacre writes "Erik Sofge trudges through NASA's latest free video game, which he finds tedious, uninspiring and misguided. Quoting: 'Moonbase Alpha is a demo, of sorts, for NASA's more ambitious upcoming game, Astronaut: Moon, Mars & Beyond, which will feature more destinations, and hopefully less welding. The European Space Agency is developing a similar game, set on the Jovian Moon, Europa. But Moonbase Alpha proves that as a recruiting campaign, or even as an educational tool, the astronaut simulation game is a lost cause. Unless NASA plans to veer into science fiction and populate its virtual moons, asteroids and planets with hostile species, it's hard to imagine why anyone would want to suffer through another minute of pretending to weld power cables back into place, while thousands of miles away, the most advanced explorers ever built are hurtling toward asteroids and dwarf planets and into the heart of the sun. Even if it was possible to build an astronaut game that's both exciting and realistic, why bother? It will be more than a decade before humans even attempt another trip outside of Earth's orbit. If NASA wants to inspire the next generation of astronauts and engineers, its games should focus on the real winners of the space race — the robots.'"
It's funny.  Laugh.

Tracking the Harm Games Do 118

Every so often, video games are accused of causing all sorts of negative behavior in children, teens, and adults. These accusations are typically predicated on statistics that sound much more damning than they actually are. In that vein, gaming website Rock, Paper, Shotgun did their own tongue-in-cheek statistical analysis, complete with pretty charts and graphs. Quoting: "As part of my research I thought to compare the sales of each GTA game with what the divorce rate must have been when each came out. As you can see each new GTA game has been directly correlated with an increase in divorces. ... An often ignored statistic (and you have to ask why it’s being ignored by the games media, don’t you?) is the sheer volume of PC games being released. We’ve all noticed the British population is abandoning the church, turning instead toward shopping, DVDs and knife crime. But few have thought to check for a connection between PC sales and the numbers of people attending their local Church Of England church on a Sunday. When you look at the data there’s little doubt left that as the publishers continue to release more and more PC games each year, our nation’s faith is being increasingly eroded. And at what cost? If only a graph could tell us that."

Nuclear Energy Now More Expensive Than Solar 635

js_sebastian writes "According to an article on the New York Times, a historical cross-over has occurred because of the declining costs of solar vs. the increasing costs of nuclear energy: solar, hardly the cheapest of renewable technologies, is now cheaper than nuclear, at around 16 cents per kilowatt hour. Furthermore, the NY Times reports that financial markets will not finance the construction of nuclear power plants unless the risk of default (which is historically as high as 50 percent for the nuclear industry) is externalized to someone else through federal loan guarantees or ratepayer funding. The bottom line seems to be that nuclear is simply not competitive, and the push from the US government to subsidize it seems to be forcing the wrong choice on the market."

NASA Revamps Historic 4-Million-kg Mars Antenna 66

coondoggie writes NASA is working on some difficult renovations to reinvigorate its 70-meter-wide 'Mars antenna.' The antenna, a key cog in NASA's Deep Space Network, needs about $1.25M worth of what NASA calls major, delicate surgery. The revamp calls for lifting the antenna — about 4 million kilograms of finely tuned scientific instruments — to a height of about 5 millimeters so workers can replace the steel runner, walls and supporting grout."

The Proton Just Got Smaller 289

inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

Activision Wants Consoles To Be Replaced By PCs 344

thsoundman writes with this excerpt from thegamersblog: "We live in a world where we have multiple platforms for gaming: PC, PS3, 360, Wii, etc. Each platform has varying amounts of power when it comes to playing games. Activision, one of the leading cross-platform publishers, wishes to move away from the 'walled gardens' set by Sony, Microsoft and Nintendo. ... [Activision CEO Bobby] Kotick’s solution is to turn to the PC, where it can set its own model for pricing — not unlike what Blizzard has done with World of Warcraft and Battle.net. Kotick stated that Activision would 'very aggressively' support the likes of HP and Dell in any attempt at making an easy 'plug-and-play' PC that would hook up directly to the TV."

Mom Arrested After Son Makes Dry Ice "Bombs" 571

formfeed writes "Police were called to a house in Omaha where a 14-year-old made some 'dry ice bombs' (dry ice in soda bottles). Since his mom knew about it, she is now facing felony charges for child endangment and possession of a destructive device. From the article: 'Assistant Douglas County Attorney Eric Wells said the boy admitted to making the bomb and that his mother knew he was doing so. The boy was set to appear Tuesday afternoon in juvenile court, accused of possessing a destructive device.'" She's lucky they didn't find the baking soda volcano in the basement.

Building a Homemade Nuclear Reactor In NYC 219

yukk writes "Mark Suppes, a web developer for Gucci, is working on his own personal fusion reactor. His work in a NYC warehouse using $35,000 of his own money and $4,000 raised on a website has made him the 38th independent researcher recognized as creating a working fusion reactor. How's that for a hobby?"

Over a Third of the Internet Is Pornographic 247

Th'Inquisitor writes "Pornography makes up 37% of the total number of web pages online, according to a new study published by Optenet, a SaaS provider. According to the report, which looked at a representative sample of around four million extracted URLs, adult content on the Internet increased by 17% in the first quarter of 2010, as compared to the same period in 2009."

Doctor Slams Hospital's "Please" Policy 572

Administrators at England's Worthing Hospital are insisting that doctors say the magic word when writing orders for blood tests on weekends. If a doctor refuses to write "please" on the order, the test will be refused. From the article: "However, a doctor at the hospital said on condition of anonymity that he sees the policy as a money-saving measure that could prove dangerous for patients. 'I was shocked to come in on Sunday and find none of my bloods had been done from the night before because I'd not written "please,"' the doctor said. 'I had no results to guide treatment of patients. Myself and a senior nurse had to take the bloods ourselves, which added hours to our 12-hour shifts. This system puts patients' lives at risk. Doctors are wasting time doing the job of the technicians.'"

Comment Countdown - a game ahead of its time (Score 1) 325

When this game opens, you find yourself prisoner in a Turkish mental hospital on the eve lobotomy surgery. Sure, the graphics and gameplay are outmoded, but the game was ahead of its time with international settings, uh, interesting characters (e.g., Rachel Akure, Mossad agent), a duplicitous girlfriend, and a plot line that would intrigue any 9-11 conspiracy theorist. All from 1990! Alas, getting this to run properly on Windows 7 x64 or even Windows Vista has proved to be a chore. The program can't always find its DOS mouse driver and sound board without crashing. http://en.wikipedia.org/wiki/Countdown_(video_game)
