In order to help customers find what they want quickly, it's important to keep the thousands of titles in the Main Street Movies store organized properly. This section of the Employee Handbook will tell you how to organize videos.

    Each Main street Movies store has three main sections:

1). New Releases Wall.

2). Film library.

3). Video Games.

    New Releases Wall. Almost 70 percent of movie rentals are new releases, and that is the first place where most customers go when they enter the store. The center section of shelves on this wall holds Hottest Hits. When new titles come into the store, place them on this wall in alphabetical order. The shelves beside Hottest Hits are called Recent Releases. The New Releases Wall, including the Hottest Hits and Recent Releases shelves, holds about 350 titles.

    Film Library. The thousands of titles in the Film Library are organized into categories. The films within each category are displayed alphabetically. Here are the categories and their two-letter computer codes:

    Foreign Language titles include films that were originally made in a foreign language and films with foreign language subtitles. A sticker on the back of each box tells which type of film it is.

    Video Game. All the video games in Main street Movies are arranged in alphabetical order. Although video games represent only a small percentage of our inventory(库存), they are stolen more often than any other type of goods in our store. Therefore, video games are never displayed on the shelves. Shelves in the Video Game section hold cardboard with pictures and information about each game. When a customer wants to rent a particular game, you then find the game from the locked case behind the counter.

    It encouraged us to visit Quora. com, the online question and answer community, to find out how users get the most out of every tank of gas.

    Light makes right

    Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.

    Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.

    Keep the pressure up

    Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.

    Air conditioning or windows

    Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.

    Achilleas Vortselas said it would depend largely on a car's speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car's aerodynamic(空气动力的) characteristics would be influenced by opened windows.

    More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.

    “Cleverness is a gift while kindness is a choice. Gifts are easy – they're given after all. Choices can be hard.” –– Jeff Bezos.

    I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I'd never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I'd been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't, and I wasn't sure what to expect. MacKenzie told me I should go for it. As a young boy, I'd been a garage inventor. I'd always wanted to be an inventor, and she wanted me to follow my passion.

    I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately, I decided I had to give it a shot. I didn't think I'd regret trying and failing. And I suspected I would always be haunted by a decision to not try at all.

    After much consideration, I took the less safe path to follow my passion, and I'm proud of that choice. For all of us, in the end, we are our choices.

    Mya Le Thai is a scientist studying at the University of California, Irvine. She recently discovered a process that may result in batteries that last forever. Thai said she had been discouraged that the batteries for her wireless devices degrade. Over time, they fail to charge fully.

    Thai did not like to have keep her wireless laptop connected to an electrical outlet. She decided to do something about that problem.

    At first, she and her team thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子) batteries to last forever. Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die.

    One of the reasons lithium-ion batteries degrade is their use of nanowires(纳米线) to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries. But Thai said their thinness also makes them weak. "Nanowires break over time," she said. "That's why they lose capacity."

    But, Thai had a theory: The nanowires might last longer if covered with a material. She and the team tested her theory. The team tried many coverings for the wires. PMMA was one of them. The nanowires were coated with PMMA and cycled through charges 200,000 times. The PMMA coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

    Thai hopes to continue her research to understand why this material works so well and to see if any other material could create better results.

"It's kind of cool," she said. "I'm really glad people are showing interest in my work and not just in the work itself, but also in technology and energy."

    Moments before I could lift my case to put it in the plane's overhead locker ahead of our recent holiday to Europe, my father gently urged me to stop. He held the thick handles of the case and lifted it with his thin arms, pushing it into place with a sigh. “You should relax and be the lady, and let me do the heavy tasks,” he said seriously. “In the future, someone special will come into your life and take over such tasks from me, but that will never happen if you do everything yourself.”

    I was stunned into silence. This was not the father I remembered from childhood, who trained me to study hard at school, asked me to earn my own pocket money as a teenager at a local coffee shop, and even taught me household chores so that my life alone in London wouldn't turn into a mess. But then, eight years after I left home and started a new life in the UK, I realized for the first time that my dad still has expectations for me to be like a princess and to stay dependent and delicate, which were considered necessary qualities of women in traditional China.

    Well, that came a little late. Little did Dad know that over the three years of my university life, I moved flats five times all by myself, dragging suitcases of books and clothes, and waiting for the taxi in the rain while holding tight onto cardboard boxes. Meanwhile, living in the UK – a country currently led by a female prime minister – I have never thought there is anything girls cannot do. Most of my female friends are professionals working in the City of London, and after work, we frequently go down to the pub for a drink, just like the guys do – something my mother never did.

    I wondered how I might make Dad understand the new world his little girl has entered. Perhaps one day, he will realize the “someone special” in my life will appreciate my confidence and independence above dependence, and admit that times have changed.

    Zachariah Fike has an unusual hobby. He finds old military（军队的）medals for sale in antique stores and on the Internet. But unlike most collectors, Zac tracks down the medals' rightful owners, and returns them.

    His effort to reunite families with lost medals began with a Christmas gift from his mother, a Purple Heart with the name Corrado A. G. Piccoli, found in an antique shop. Zac knows the meaning of a Purple Heart-he earned one himself in a war as a soldier. So when his mother gave him the medal, he knew right away what he had to do.

    Through the Internet, Zac tracked down Corrado's sister Adeline Rockko. But when he finally reached her, the woman flooded him with questions: "Who are you？What antique shop?" However, when she hung up, she regretted the way she had handled the call. So she called Zac back and apologized. Soon she drove to meet Zac in Watertown, N.Y. "At that point, I knew she meant business," Zac says. "To drive eight hours to come to see me."

    The Piccolis grew up the children of Italian immigrants in Watertown. Corrado, a translator for the Army during WWII, was killed in action in Europe.

    Before hearing from Zac, Adeline hadn't realized the medal was missing. Like many military medals, the one Zac's mother had found was a family treasure." This medal was very precious to my parents. Only on special occasions（场合）would they take it out and let us hold it in our hands," Adeline says.

    As a child, Adeline couldn't understand why the medal was so significant. “But as I grew older,” Adeline says, "and missed my brother more and more, I realized that was the only thing we had left." Corrado Piccoli's Purple Heart medal now hangs at the Italian American Civic Association in Watertown.

    Zac recently returned another lost medal to a family in Alabama. Since he first reunited Corrado's medal, Zac says his record is now 5 for 5.
