The Science of Rail Guns



The Science Of Rail Guns -- io9 News

Ubiquitous in science fiction, rail guns are a hot area of military research in real life too. But will we ever really get to use them the way people in science fiction do? And could rail guns be used for a non-violent reason — inexpensively launching payload into space?

Halo Reach ends with your Spartan taking up a mounted rail gun to destroy an incoming Covenant ship. Rail guns are the basis for a funny aside in Mass Effect 2. They're used in Babylon 5 and Stargate Atlantis and The Last Starfighter. And they're a devastating hand-held weapon in the Metal Gear Solid and Quake series. Now, let's discover the real science behind rail guns.

Meet The Man Who Broke The Bank At Three Casinos

Wilk

The Man Who Broke Atlantic City -- The Atlantic

Don Johnson won nearly $6 million playing blackjack in one night, single-handedly decimating the monthly revenue of Atlantic City’s Tropicana casino. Not long before that, he’d taken the Borgata for $5 million and Caesars for $4 million. Here’s how he did it.

Don Johnson finds it hard to remember the exact cards. Who could? At the height of his 12-hour blitz of the Tropicana casino in Atlantic City, New Jersey, last April, he was playing a hand of blackjack nearly every minute.

Dozens of spectators pressed against the glass of the high-roller pit. Inside, playing at a green-felt table opposite a black-vested dealer, a burly middle-aged man in a red cap and black Oregon State hoodie was wagering $100,000 a hand. Word spreads when the betting is that big. Johnson was on an amazing streak. The towers of chips stacked in front of him formed a colorful miniature skyline. His winning run had been picked up by the casino’s watchful overhead cameras and drawn the close scrutiny of the pit bosses. In just one hand, he remembers, he won $800,000. In a three-hand sequence, he took $1.2 million.

My Comment: My pockets are empty and my luck is not that great. Sighhh .... best stick to buying my weekly $5 loto ticket.

Nodding Disease



Mysterious Nodding Disease Debilitates Children -- CNN

Pader, Uganda (CNN) -- Pauline Oto still wears her faded yellow and green school dress, but she hasn't been to school for years and she can't comprehend what to do with the pen the community nurse has just given her.

"Write on my hand," says the nurse. Pauline just sits on the reed mat, her legs pulled to one side, and stares. She has just had an attack and can't speak. She struggles to comprehend her surroundings.

Pauline, 13, has been struck by the dreaded nodding disease. Her mother, Grace Lagat, says it will take her at least four hours to recover from the seizures, and after each attack she seems less like the daughter she remembers.

Spring Arrives With Equinox Tuesday, Earliest In More Than A Century -- Scientific American

Spring is arriving early in a meteorological sense in the Eastern U.S., and in an astronomical sense, making its earliest arrival since 1896.

Across much of the United States, this has been an unusually mild winter, especially for those living east of the Mississippi. Not a few people have noted that spring seems to have come early this year. Of course, in a meteorological sense that could be true, but in 2012 it will also be true in an astronomical sense as well, because this year spring will make its earliest arrival since the late 19th century: 1896, to be exact.

Global Sea Level Likely to Rise as Much as 70 Feet for Future Generations -- Science Daily

ScienceDaily (Mar. 19, 2012) — Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to 22 meters (40 to 70 feet) higher than at present, according to research published in the journal Geology.

The researchers, led by Kenneth G. Miller, professor of earth and planetary sciences in the School of Arts and Sciences at Rutgers University, reached their conclusion by studying rock and soil cores in Virginia, Eniwetok Atoll in the Pacific and New Zealand. They looked at the late Pliocene epoch, 2.7 million to 3.2 million years ago, the last time the carbon dioxide level in the atmosphere was at its current level, and atmospheric temperatures were 2 degrees C higher than they are now.

U.S. Accelerating Cyberweapon Research -- Washington Post

The Pentagon is accelerating efforts to develop a new generation of cyberweapons capable of disrupting enemy military networks even when those networks are not connected to the Internet, according to current and former U.S. officials.

The possibility of a confrontation with Iran or Syria has highlighted for American military planners the value of cyberweapons that can be used against an enemy whose most important targets, such as air defense systems, do not rely on Internet-based networks. But adapting such cyberweapons can take months or even years of arduous technical work.

Warm Sanctuaries Key To Human Evolution -- Cosmos

DUBLIN: Modern and ancient humans withdrew to milder sanctuaries during the Ice Ages in Europe and Asia, and these refuges became critical for human evolution, according to a new study.

New models published in a paper in Science today suggest that refugia - locations that harbour relict populations of a once-widespread species - were important in determining the pace and pattern of the massive human migration from Africa, which began approximately 100,000 years ago.

New Zealand Police Made 'Errors' During Raid On Megaupload Boss

Web domains belonging to Megaupload have been seized and shut down

Police Made 'Errors' During Raid On Megaupload Boss -- BBC

A police blunder could mean luxury cars, giant TVs and jewellery seized during a police raid will be returned to Megaupload owner Kim Dotcom.

The property was confiscated during a dawn raid on the New Zealand home of the file-sharing site's owner.

A New Zealand judge has now ruled that the court order used to justify the seizure should never have been granted.

The raid led to the closure of Megaupload and seizure of the web domains it used.

Judge Judith Potter said the court order should now be considered "null and void".

My Comment: At least Megaupload founder Kim Dotcom can now pay his lawyers.

How Snails Are Generating Electrical Power Via Through A Tiny Biofuel Cell Implant

Cyborg Snails Generate Electrical Power From Their Blood-Like Fluid -- National Geographic

Just a few weeks ago we wrote about scientists who’d manage to draw power from the body fluids of cockroaches. Now, another team has reported achieving a similar feat with snails: a tiny biofuel cell implanted in the creatures draws glucose and oxygen from their hemolymph (the snail equivalent of blood) to generate power. And a yet-to-be-released study, Nature News reports, will feature beetles as the carriers of these minute power cells. All of this tiny cyborg excitement can be traced back to a 2003 paper, in which scientists generated power from a grape. Importantly, all of these biological generators—except, presumably, the grape—survived and thrived after their operations.

My Comment: A prediction .... if the science is sound, it can eventually help power prosthetics and medical implants.

Another Version Of The Supersonic Jet Of The Future

The Supersonic Jet Of The Future Will Be A Biplane -- Popular Science

When supersonic travel inevitably returns to the skies, the airplanes are going to look a lot different. At least one design harks back to the early days of aviation with a biplane design, rather than a sleek delta-winged jet like the Concorde. This shape can apparently produce much less drag and therefore much less noise at supersonic speeds, MIT engineers say.

The decreased drag would make a supersonic biplane more fuel-efficient and it would produce a quieter sonic boom, because the shock waves propagating toward the ground would be canceled out. The trick is getting it to fly.

The End Of Windpower?

Broken promises: The rusting wind turbines of Hawaii

Broken Down And Rusting, Is This The Future Of Britain's 'Wind Rush'? -- Daily Mail

A breathtaking sight awaits those who travel to the southernmost tip of Hawaii’s stunningly beautiful Big Island, though it’s not in any guidebook. On a 100-acre site, where cattle wander past broken ‘Keep Out’ signs, stand the rusting skeletons of scores of wind turbines.

Just a short walk from where endangered monk seals and Hawksbill turtles can be found on an unspoilt sandy beach, a technology that is supposed to be about saving the environment is instead ruining it.

My Comment: It does not look promising.

The Computer’s Next Conquest: Crosswords -- New York Times

What’s a 10-letter word for smarty pants?

This weekend the world may find out when computer technology again tries to best human brains, this time at the American Crossword Puzzle Tournament in Brooklyn.

Computers can make mincemeat of chess masters and vanquish the champions of “Jeopardy!” But can the trophy go to a crossword-solving program, Dr. Fill — a wordplay on filling in a crossword and the screen name of the talk show host Dr. Phil McGraw — when it tests its algorithms against the wits of 600 of the nation’s top crossword solvers?

Health Risks Associated With White Rice

Eating White Rice Daily Ups Diabetes Risk, Study Shows -- CBS

(CBS News) White rice is a dietary staple for more than half the world's population - not just for people living in China, India, and Japan, but for many Americans as well.

A new study from the Harvard School of Public Health shows people who eat lots of white rice may significantly raise their risk of developing type 2 diabetes.

Harvard researchers analyzed four earlier studies on white rice consumption that involved more than 352,000 people from China, Japan, U.S., and Australia, who did not have diabetes. The researchers found after follow-up periods that ranged from four to 22 years, that almost 13,400 people had type 2 diabetes. People who ate the most rice were more than 1.5 times likely to have diabetes than people who ate the least amount of rice. What's more, for every 5.5 ounce-serving of white rice - a large bowl - a person ate each day, the risk rose 10 percent.

McCain Sees Another Solyndra In Navy Biofuels Spending -- The Hill

The Navy’s push to develop biofuels to run its fleet of planes and warships could devolve into a “Solyndra situation” for the Pentagon, a top Republican senator said today.

During Tuesday’s hearing of the Senate Armed Services Committee, ranking member John McCain (R-Ariz.) compared the now-bankrupt solar energy company, into which the White House sank $535 million in loan guarantees, to Navy-led efforts in alternative energy.

....

My Comment: What caught my eye was the following ....

.... But Sen. James Inhofe (R-Okla.) pointed out that even at a competitive price, the Navy’s plan to use a “50/50 blend” of diesel fuel and a biofuel supplement would still cost $15 per gallon. Traditional JP-5 jet fuel used in the Navy’s fighter aircraft runs $4 to $5 per gallon on average, Inhofe said.

$15 per gallon !!!!! .... you've got to be kidding me. And what is even worse is that these are just projections .... projections from a government agency that has a lousy record in projecting anything.

Bottom line .... it is too expensive and if implemented will help in busting the defense department's budget. My suggestion .... go back to the drawing board and find an alternative plan that is more practical and economically feasible.

What Top Secret NSA Data Center?

NSA Keeping Details About Data Center Quiet -- KSL.com

BLUFFDALE — The $1.5 billion spy complex being built for the National Security Agency is becoming more conspicuous as construction advances at Camp Williams within sight of traffic on I-15.

But the agency building 1 million square feet of enclosed space, including 100,000 square feet of space just for computers that will gather and digest intelligence information, continues to do what it does best — keep secrets — when asked about the project.

The NSA sent a short statement to the Deseret News on Friday, but only after Wired Magazine compiled a voluminous story published the same day. The broadly researched story builds the skeleton of its story using information NSA released at its January 2011 groundbreaking and puts meat and skin on that skeleton with anecdotal data from the computer and information technology industries.

One thing the Utah Data Center is not likely to run short of: really big numbers.

Want To Live Longer .... Make Friends

You Want To Live To 1,000? Start Making Friends -- The Guardian

Loneliness is the worst enemy for the health of old people.

This week, to a large and gripped audience, Professor Sarah Harper from the Oxford Institute of Ageing had just explained what societies of the future would look like. Then someone in the audience stood up and quoted gerontologist Aubrey de Grey: "The person who lives to be 1,000 has already been born."

To think of our children living into their 100s is, it seems, at the vanilla end of the ageing debate now. Conceivably, you could retire in your sixties, become transformed by stem cell regeneration or similar, go back to work at 100, work for another 800 years, and still have a really long retirement.
