Watching quantum mechanics in action: Researchers create world record laser pulse

ScienceDaily (Sep. 4, 2012) ? A University of Central Florida research team has created the world's shortest laser pulse and in the process may have given scientists a new tool to watch quantum mechanics in action -- something that has been hidden from view until now.

UCF Professor Zenghu Chang from the Department of Physics and the College of Optics and Photonics, led the effort that generated a 67-attosecond pulse of extreme ultraviolet light. The results of his research are published online under Early Posting in the journal Optics Letters.

An attosecond is an incomprehensible quintillionith of a second. In other words it would take 15 million billion pulses of the size Chang's team achieved to equal one second. The accomplishment is even more remarkable because the team did it without the use of specialized equipment including a mile-long particle accelerator or a Superdome-sized synchrotron.

"Dr. Chang's success in making ever-shorter light pulses helps open a new door to a previously hidden world, where we can watch electrons move in atoms and molecules, and follow chemical reactions as they take place," said Michael Johnson, the dean of the UCF College of Sciences and a physicist. "It is astounding to imagine that we may now be able to watch quantum mechanics in process."

Quantum mechanics is the study of physics at the microscopic level, specifically looking at energy and matter on this miniscule scale.

There is much excitement about the accomplishment and the promise Chang's work holds for helping scientists understand how the world's smallest building blocks actually work. The technique could lead scientists to understand how energy can be harnessed to transport data, deliver targeted cancer therapies or diagnose disease. The finding marks the first significant breakthrough in the laser pulse field in four years.

In 2001, attosecond pulses were demonstrated for the first time. Since then scientists around the world have been trying to make ever-shorter pulse durations because of the door they could open to understanding the subatomic world. The previous record of an 80-attosecond pulse was set in 2008 at the Max Planck Institute in Garching, Germany. This is the first time an American-led team has set the record.

"The quest for generating shorter and shorter pulses of light has been ongoing since the invention of the laser more than five decades ago," said Bahaa Saleh, dean of CREOL, the College of Optics and Photonics. "Dr. Chang's recent advance brings UCF to the forefront of this Olympic race and opens up new frontiers for seeing and recording ultrafast dynamic atomic phenomena."

Chang's team was able to accomplish the work at the Florida Atto Science &Technology (FAST) lab in UCF's Physical Sciences building.

Using the unprecedented power of laser light enables Chang and his peers to conduct their high-level research in much smaller spaces. Chang's group created a technique called Double Optical Grating that allows extreme ultraviolet light to be cut off in a manner that concentrates the maximum amount of energy in the shortest possible pulse of light. With the affinity for acronyms shared by many ultrafast laser physicists, Chang named the technique DOG. In addition to creating the light pulse, he created an even faster camera to measure it, which is the Phase Retrieval by Omega Oscillation Filtering (PROOF).

The Department of Defense's Multidisciplinary University Research Initiative and the National Science Foundation helped fund the research.

Others who contributed to the team's discovery include: Kun Zhao, Qi Zhang, Michael Chini, Yi Wu, and Xiaowei Wang, all at UCF. UCF Stands For Opportunity --The University of Central Florida is a metropolitan research university that ranks as the second largest in the nation with more than 59,000 students. UCF's first classes were offered in 1968. The university offers impressive academic and research environments that power the region's economic development. UCF's culture of opportunity is driven by our diversity, Orlando environment, history of entrepreneurship and our youth, relevance and energy.

Home Flipping vs Real Estate Investing The Distinctions Between ...

Which is superior: home flipping or real estate investing?

To get to an answer, it helps to explain each word and put them in perspective.

Home flipping is the process of buying a house then selling it for a profit within the quickest time possible. An investor is aiming to make a good sum of profit within a very short period of time, thus the word flipping.He/she does not hold onto it for the purposes of income. As a matter of fact, the shorter they hold the house, the better it is.

Real estate investing is all about buying and holding real estate then either keeping the house for a while and selling or keeping it for rental income.

The real estate investor might buy the property with the purpose of selling it at some time, but may hold onto the house for many years.

Which is right for you?

The most major difference is a house flipper wants quick cash profits but the real estate investor wants income and appreciation.

House flippers target houses that they can buy at a cheaper rate than the normal market rate. In doing it this way, the house flipper locks in fast profits.

Frequently, the real estate is purchased at a cost significantly less compared to its market price (in the range from 40-80% below the prevailing market prices).

Totally gutting an old beat up house is a popular way that most house flippers get started. The house flip pro purchase the house, quickly renovates it and then sells it under a month or so.

Renovating is much cheaper as one can precisely estimate the cost of materials and labor required to do it. It can be possible to get industry experts in the specific refurbishments considered necessary and therefore the house will have a very good look in the end.

This enables the home flipper to get a fast market for the home and at the same time fetching a really good price for the house.

Flipping houses is less of a hassle because you dont need to deal with renters and other kinds of landlording issues. the house lfipperbuys, renovates and sells, its very simple.

Where a house flipping pro works is important as well and this depends on the local real estate market in large part, more money can be made if the market allows for a quick sale. This is in contrast to real estate investing where the investor has to wait for long periods before the property can be completed and sold to make a profit..

In buy and hold real estate investing, the scheme is more long term and for investors looking for a steady income. A major advantage is if the market is poor he can hold on and receive income and not worry about resale.

Additionally, the buy and hold real estate investor can also leverage bulk buying of renovation materials if he is going to do multiple properties at once

I am purely biased, but house flipping is my preferred way of making money in real estate, what do you think?

AUBURN, Ind. ? A military museum in northeastern Indiana will remain open under an agreement to end a bank's foreclosure lawsuit.

The deal announced Thursday by the Dean V. Kruse Foundation calls for it to sell the unused building on which it owes $2.9 million to Farmers State Bank of LaGrange. The foundation built it to house the memorabilia of auto racing icon Andy Granatelli who changed his mind about using the Auburn location.

The Star of Auburn and The Journal Gazette report that a DeKalb County judge had ordered the sale of the Kruse Foundation museums site, which includes the National Military History Center.

The Granatelli building will be auctioned off Sunday and some military museum items will be sold in November to help pay off the loan.

Celebs and pols: When the star alliance misfires

NEW YORK (AP) ? In the aftermath of Clint Eastwood's perplexing and ridiculed "invisible Obama" monologue at the Republican National Convention, conservative blogger Moe Lane summed up what many on both sides of the political divide are thinking.

"The term 'surfing on the edge of the catastrophe curve' comes to mind," Lane wrote at RedState, concluding the bit that had the 82-year-old Hollywood icon talking to an empty chair did work but, "I would not recommend that the GOP make it a habit."

Celebrities have courted politicians, and vice versa, since the dawn of Hollywood, but what happens when the alliance backfires, when the two worlds are suddenly speaking different languages?

The crowd Thursday night at the Tampa Bay Times Forum, just ahead of Romney's "speech of a lifetime," greeted the Eastwood Moment with hearty laughter and applause, a welcome break of levity on the last day of a tightly choreographed convention.

But behind the scenes, Romney's campaign staff didn't find it so humorous. Asked about it immediately after the convention concluded, a half-dozen staffers said little. The campaign quickly went into damage control.

Unlike every other convention speaker, the teleprompter in the hall wasn't used during Eastwood's speech, which had him lampooning President Barack Obama as if he were there. The routine from the Oscar-winning director of "Unforgiven" and "Million Dollar Baby" lasted twice as long as scheduled, cutting into the hour of prime time coverage for Republicans.

It also sucked up Friday morning coverage of Romney's speech that had him accepting the Republican nomination for president.

On "CBS This Morning," Ann Romney cast about for words. Asked whether his contribution was a distraction or a mistake, she responded: "He's a unique guy and he did a unique thing last night." But the wife of the new nominee was quick to add that "we're grateful for everyone's support and especially grateful for what a great night it was last night."

Grateful, too, like plenty of politicians, for any financial support that comes along with celebrity pals, though Eastwood's bucks may not be in the mix.

Eastwood endorsed Romney on Aug. 3, in Sun Valley, Idaho, where he attended a fundraiser, so any money he would have contributed personally or through his company hasn't turned up yet in financial records filed with the Federal Election Commission. After the fundraiser, Eastwood let the campaign know he was interested in participating in the convention, a Romney aide said.

In this world of oversharing, when the like-minded or contrary are only a tweet away, social media blew up over Eastwood's confusing convention appearance, along with political-pundit quarterbacking on both ends of the spectrum.

"It ... was odd. Not consistently terrible as some argued," observed National Review's Jim Geraghty. "I have no doubt some folks loved it. It may very well have actually moved some votes. But boy, did it get weird at times."

What of the visible president? Was he watching, and taking notes on how to manage his crowded stable of actors and artists among friends and supporters?

White House spokesman Jay Carney said Obama had no observations on Eastwood's appearance. Nor did he watch the Republican convention, the spokesman said, but his official feed on Twitter ? (hashtag)BarackObama ? most certainly did.

"This seat's taken," the account tweeted late Thursday as Twitter exploded with mockers ? and some supporters.

Discomfort or mere awkwardness aside, it's rare for a celebrity endorsement to backfire in a big way, said Steve Ross, a professor of history at the University of Southern California who has studied the impact of star endorsements in political campaigns.

While some stars, such as Jane Fonda, have proven toxic (she went to North Vietnam during the war in 1972), Eastwood carries enough gravitas and respect that he will get more people to pay attention to Mitt Romney, Ross said.

Eastwood is no Jane Fonda.

In 1986, a Missouri Senate candidate was pilloried for the simple acceptance of $2,000 from the actress. The candidate, the now-dead Harriet Woods, was branded "Hanoi Harriet," linking her to Fonda's "Hanoi Jane" moniker, and she lost the election, Ross said.

Nor is Eastwood a regular contributor of political punditry or skewering standup routines.

"This isn't Jeff Foxworthy. This isn't some comedian," Ross said. Eastwood is "Mr. Law and Order. I can't think of a bigger national spokesperson they could get."

Yet freewheeling celebrities do bring their risks:

? Though far from a catastrophe, during a stop at an Obama fundraiser in March, Robert De Niro found himself at the center of a White House apology over a joke about candidates' wives.

"'Callista Gingrich. Karen Santorum. Ann Romney. Now do you really think our country is ready for a white first lady?' De Niro asked the crowd, according to a White House pool report.

Gingrich howled. The White House apologized, and so did the actor.

? George Clooney, the Hollywood darling of the Obama administration, got arrested outside the Sudanese Embassy in Washington that same month, managing to suck up plenty of limelight after traveling to the troubled region himself and testifying before the Senate.

? In 2008, Scarlett Johansson got a little too close for Obama's comfort. She claimed publicly that she had his ear in regular personal email exchanges after she endorsed him. Not so, the embarrassed candidate had to explain. There had been one email, forwarded by an aide.

? It was an "Oprahpalooza" during primary season in 2007. The talk show queen endorsed Obama and stumped in Iowa before thousands, detracting hugely from Hillary Rodham Clinton's two surrogates, mom Dorothy Rodham and daughter, Chelsea, both appearing publicly for the first time. The reluctant Chelsea Clinton's emergence would otherwise have been big news.

Linking celebrities to candidates was a process that started in the late '20s, when movie stars were sent on the road to stump with politicians, Ross said. The idea was to draw in more people ? many of whom would leave after seeing the star but others who would stay and listen to the candidate's message.

Capitalizing on celebrity culture to capture new votes, especially among the undecided, was the value, he said.

"This has been the key idea whether it was 1928 or 2012 with Clint Eastwood," Ross said.
