Since Edmund Hillary and Tenzing Norgay climbed Mount Everest, Mount Qomolangma's peak is no longer a lonely place and is turning into a trash heap.

    So far, more than 350 climbers have successfully reached the peak. And they have complained about waiting for hours in the bottlenecks (狭窄路段) on the way to the peak, a situation that isn't just uncomfortable — it's cold and windy up there — but downright dangerous. If bad weather strikes, climbers can and do die.

    As a matter of fact, the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of gear—and much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's largest dump. Here's mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: “The two standard routes, the Northeast Ridge and the Southeast Ridge, are disgustingly polluted with oxygen cans and torn tents everywhere.”

    But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountianeer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since 2008. So far they've collected over 13 tons of garbage.

    Some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They've transformed the cans and oxygen tanks—and in one case, part of the remains of a helicopter—into 74 pieces of art that have already gone on exhibition in Nepal's capital. Part of the profit from sales will go to the Everest Peakers Association, which has helped collect tons of rubbish on the slopes of the mountain.

    Blind tasting is a very strange activity. Contrary to what many people imagine, it has nothing to do with blindfolds. It involves tasting a wine without seeing the label and it can deliver shocking surprises. I tasted seven champagnes (香槟) blind with a group of professionals recently. There was a shock when they discovered the wine most of them preferred carried a label they regarded as their least favorite. That sort of result is especially common with champagne, the most image-driven rather than quality-driven wine of all. But it happens all the time when wine is tasted blind.

    Because I'm interested in how wines really taste instead of how I think they should, I taste wine blind as often as I can, especially when assessing similar young wines. But blind tasting when you know absolutely nothing about the wine in front of you is something completely different. The most difficult Master of Wine exams include three sessions during which you have a dozen glasses in front of you and nothing more helpful than a printed exam paper asking you to identify each wine as closely as possible, and assess its quality.

    Now that the MW is behind me, I taste wine completely blind only very rarely, and never in public. So my blind tastings these days are round the dinner table with good friends and once a year when I act as a judge, with Hugh Johnson, in the Oxford vs Cambridge wine-tasting competition. This is the most extraordinary match, always held before the Boat Race but taken just as seriously nowadays. This year's taste-off took place at the end of last month, as usual in the Oxford and Cambridge Club on Pall Mall in London.  

    Now many young people are traveling around the world on their own，not because they have no one to travel with，but because they prefer to go alone.

Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries，with no one to help you read a map，look after you if you get ill，or lend you money if your wallet is stolen，it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website，The Aussie Nomad，to document his adventures. He says he wished he had traveled alone earlier. “The people you meet，the places you visit，or the things you do，everything is up to you and it forces you to grow as a person，” said the 30-year-old man.

    Richardson describes traveling alone like "a shot in the arm"，which "makes you a more confident person that is ready to deal with anything". He said，"The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19th century explorer John Muir once said，"Only by going alone in silence can one truly get into the heart of the wilderness."

    Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents' home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register (收款台), I said hello to an older couple who were also paying for gas.

    I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend's. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.

    I wrote him and his wife a thank­you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

    Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I'd left the lights on all day, and the battery (电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom.

    “Just how friendly is Friendly Ford?” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

    “Thank you” — two powerful words. They're easy to say and mean so much.

When Jeff Sparkman draws his cartoon superheroes with coloured pencils, he often has to ask other people to tell him what colour his masked men turned out to be because he's colour blind. Now, a new smart phone application (app) can help him figure out what colours he's using and how the picture looks to most everyone else.

The DanKam app, available for iPhone and Android for $2.99, is an application that turns the vague (模糊的) colours that one percent of the population with colour-blindness see into the "true" colours as everyone else sees them. In America, an estimated 32 million colour-blind Americans—95% are males—can soon have their life improved.

"DanKam takes the stream of data coming in through the phone's camera and changes the colours slightly so they fall within the range that people who are colour-blind see," developed Dan Kaminsky told CNET. He came up with the idea after watching the 2009 film Star Trek with a colour-blind friend.

It was then that he got to know more about colourblindness like its varying types and degrees. A vast majority, for instance, have trouble seeing red or green due to a genetic defect (遗传缺陷), Blue-yellow colourblindness, however, is rarer and develops later in life because of aging, illness or head injuries, etc. He started experimenting with one of the most common representations of points in the RGB colour model. What the DanKam app attempts to do is clean up the colour space of the image or video signal so that colours can be visible to those suffering from viewing problems. "You can adjust the app to fit your needs. There is a range and not everyone who is colour-blind sees things the same," Says Kaminsky.

Sparkman, a copy editor at CNET, tried out the app and was pleased with the result: "It would be useful for dressing for a job interview," he said. But using it for his art is "the most practical application". It worked well on LED and other lights on electronic gadgets (器械), which means Sparkman can now identify the power light on his computer display green.
