Physicists demonstrate an actual tractor beam in the lab star trek style

Space the Final Frontier … well this is amazing.

It seems like we’re getting closer to the Star Trek future by leaps and bounds these days. We recently learned that a NASA scientist has set his sights on building a warp drive, and now news has come in that a team of physicists have built their own tractor beam in the lab. Now, it’s nothing to get too excited over — they used an optical beam to pull a 30 micrometer silica sphere suspended in water — but the demonstration proved that a tractor beam can actually exist.

But up until this point no one has been able to prove that a Bessel beam can actually function as a kind of tractor beam. So, in an effort to make it work, physicists David Ruffner and David Grier sought to harness a rather unique property of Bessel beams.
Specifically, these laser beams are capable of reconstructing themselves on the opposite side of an object. Subsequently, the theory is that these beams can pull an object back towards the stream of light — not unlike a tractor beam.

Sarah Palin Shuck and Jive remarks

It’s crazy how politics can bring the worst out of people. Whether those remarks were intentional or not the fact remains that of course during these theatrical act of elections such acts of demagoguery  are employed to enraged and rally people.

Former vice presidential candidate Sarah Palin released a statement on her Facebook page accusing President Obama of engaging in “shuck and jive shtick” regarding last month’s attack in Benghazi, Libya.

For those who aren’t familiar with the phrase, “shuck and jive” is a racially-tingedexpression. According to the user-submitted Urban Dictionary, the term “originally referred to the intentionally misleading words and actions that African-Americans would employ in order to deceive racist Euro-Americans in power, both during the period of slavery and afterwards.”

As Politico points out, this isn’t the first time the phrase has come up and inspired controversy. Several years ago, Andrew Cuomo, then New York’s Attorney General, used the expression while campaigning for Hillary Rodham Clinton. “You can’t shuck and jive at a press conference. All those moves you can make with the press don’t work when you’re in someone’s living room.”
Cuomo was promptly blasted by CNN’s Roland Martin, who wrote, “‘Shucking and jiving’ have long been words used as a negative assessment of African Americans, along the lines of a ‘foot shufflin’ Negro.’ In fact, I don’t recall ever hearing the phrase used in reference to anyone white.”

Don’t do the crime, if you can’t do the time. Just because he gave charity, does it mean that he should get a break from the law. Two years is loo light a sentence. This once again shows that so called white-collar crime goes under-punished.

NEW YORK (Reuters) – Disgraced Wall Street titan and philanthropist Rajat Gupta was sentenced to only two years in prison, a much lighter sentence than U.S. prosecutors had demanded, even though the federal judge who imposed it on Wednesday called his insider trading crimes “disgusting” and “a terrible breach of trust.”

Gupta was also ordered to pay a $5 million fine. He was convicted in Manhattan federal court last June for leakingGoldman Sachs boardroom secrets to Raj Rajaratnam, the hedge fund manager at the center of a U.S. government crackdown on insider trading over the past four years.
Some legal experts said the sentence came as a surprise, while others said the judge struck a fine balance.
U.S. District Judge Jed Rakoff told a somber courtroom audience, including Gupta’s wife and four adult daughters, that the illegal sharing of corporate secrets at the height of the 2008 financial crisis “was the functional equivalent of stabbing Goldman in the back.”

Richard Mourdock-nader-nazemi-rape-God-plan

Richard Mourdock condones the act of rape and calls it God’s plan …

I can’t believe this kind of thinking still goes on in one of the world’s most advanced nations. But then again … stranger things have happened…

Indiana Republican Senate candidate Richard Mourdock said pregnancies resulting from rape are part of God’s plan, tearfully explaining that he only supports abortions when a mother’s life is in danger.

“I think even when life begins in that horrible situation of rape, that it is something that God intended to happen,” Mourdock said during Tuesday’s Senate debate, choking up. Mourdock’s opponent, Democratic Rep. Joe Donnelly, opposes abortion except in cases of rape and incest.
After the debate, Mourdock further explained his comment.
“Are you trying to suggest somehow that God preordained rape, no I don’t think that,” said Mourdock, according to The Associated Press. “Anyone who would suggest that is just sick and twisted. No, that’s not even close to what I said.”

Top Oil Producers-nader-nazemi

This is fascinating. 

NEW YORK (AP) — U.S. oil output is surging so fast that the United States could soon overtake Saudi Arabia as the world’s biggest producer.

Driven by high prices and new drilling methods, U.S. production of crude and other liquid hydrocarbons is on track to rise 7 percent this year to an average of 10.9 millionbarrels per day. This will be the fourth straight year of crude increases and the biggest single-year gain since 1951.

The Energy Department forecasts that U.S. production of crude and other liquid hydrocarbons, which includes biofuels, will average 11.4 million barrels per day next year. That would be a record for the U.S. and just below Saudi Arabia’s output of 11.6 million barrels. Citibank forecasts U.S. production could reach 13 million to 15 million barrels per day by 2020, helping to make North America “the new Middle East.”

The United States will still need to import lots of oil in the years ahead. Americans use 18.7 million barrels per day. But thanks to the growth in domestic production and the improving fuel efficiency of the nation’s cars and trucks, imports could fall by half by the end of the decade.

IHS says the oil and gas drilling boom, which already supports 1.7 million jobs, will lead to the creation of 1.3 million jobs across the U.S. economy by the end of the decade.

“It’s the most important change to the economy since the advent of personal computers pushed up productivity in the 1990s,” says economist Philip Verleger, a visiting fellow at the Peterson Institute of International Economics.

The major factor driving domestic production higher is a newfound ability to squeeze oil out of rock once thought too difficult and expensive to tap. Drillers have learned to drill horizontally into long, thin seams of shale and other rock that holds oil, instead of searching for rare underground pools of hydrocarbons that have accumulated over millions of years.

To free the oil and gas from the rock, drillers crack it open by pumping water, sand and chemicals into the ground at high pressure, a process is known as hydraulic fracturing, or “fracking.”
Production from shale formations is expected to grow from 1.6 million barrels per day this year to 4.2 million barrels per day by 2020, according to Wood Mackenzie, an energy consulting firm. That means these new formations will yield more oil by 2020 than major oil suppliers such as Iran and Canada produce today.
But Saudi oil is cheap to tap, while the methods needed to tap U.S. oil are very expensive. If the price of oil falls below $75 per barrel, drillers in the U.S. will almost certainly begin to cut back.
The International Energy Agency forecasts that global oil prices, which have averaged $107 per barrel this year, will slip to an average of $89 over the next five years — not a big enough drop to lead companies to cut back on exploration deeply.

Obama – Romney debate talking about Horses and Bayonets

That was a hilarious retort and comeback from Obama. I mean I started to laugh out loud.

Monday night’s final presidential debate didn’t break any social-media records—but it did provide what many on Twitter felt was a delightfully ridiculous moment.

Total Twitter activity around the debate was the lowest of the three presidential debates, with 6.5 million tweets over the course of 90 minutes. (The first debate saw 10.3 million tweets, while the second saw 7.2 million.) The most tweeted moment was President Barack Obama’s retort to Romney’s attack about the decreasing size of the U.S. military: “We also have fewer horses and bayonets,” Obama said.
The campaigns were paying attention: After the debate, the Romney campaign purchased the promoted tweet for the hashtag #horsesandbayonets while the Obama campaign purchased the promoted tweet around searches for “bayonets.”

Lance Armstrong. How the might have fallen

How the mighty have fallen.

Lance Armstrong was stripped of his seven Tour de France titles and banned for life by cycling’s governing body Monday following a report from the U.S. Anti-Doping Agency that accused him of leading a massive doping program on his teams.
International Cycling Union President Pat McQuaid announced that the federation accepted USADA’s report on Armstrong and would not appeal to the Court of Arbitration for Sport.
”Lance Armstrong has no place in cycling and he deserves to be forgotten in cycling,” McQuaid said at a news conference. ”This is a landmark day for cycling.”
