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.  

    Scientists say we are all born with a knack for mathematics. Every time we scan the cafeteria for a table that will fit all of our friends, we're exercising the ancient estimation center in our brain.

    Stanislas Dehaene was the first researcher to show that this part of the brain exists. In 1989, he met Mr. N who had suffered a serious brain injury. Mr. N couldn't recognize the number 5, or add 2 and 2. But he still knew that there are “about 50 minutes” in an hour. Dehaene drew an important conclusion from his case: there must be two separate mathematical areas in our brains. One area is responsible for the math we learn in school, and the other judges approximate amounts.

    So what does the brain's estimation center do for us? Harvard University researcher Elizabeth Spelke has spent a lot of time posing math problems to preschoolers. When he asks 5-year-olds to solve a problem like 21+30, they can't do it. But he has also asked them questions such as, “Sarah has 21 candles and gets 30 more. John has 34 candles. Who has more candles?” It turns out preschoolers are great at solving questions like that. Before they've learned how to do math with numerals and symbols, their brains' approximation centers are already hard at work.

    After we learn symbolic math, do we still have any use for our inborn math sense? Justin Halberda at Johns Hopkins University gave us an answer in his study. He challenged a group of 14-year-olds with an approximation test: The kids stared at a computer screen and saw groups of yellow and blue dots flash by, too quickly to count. Then they had to say whether there had been more blue dots or yellow dots. The researchers found that most were able to answer correctly when there were 25 yellow dots and 10 blue ones. When the groups were closer in size, 11 yellow dots and 10 blue ones, fewer kids answered correctly.

    The big surprise in this study came when the researcher compared the kids' approximation test scores to their scores on standardized math tests. He found that kids who did better on the flashing dot test had better standardized test scores, and vice versa (反之亦然). It seems that, far from being irrelevant, your math sense might predict your ability at formal math.

    Winter Market 8th November

    This is an event for all the family. Wander among a variety of shops selling gifts while enjoying a live music show and nice street entertainment.

    The lower East Side is neither rich nor beautiful, but it can be a good place to shop.

    On Sundays, its streets are crowded with visitors and shoppers like these. They are trying to find a coat or a pair of shoes at a good price.

    Most people prefer to shop in the big department stores like Macy's, Gimbel's, or Bloomingdale's because there they can find clothing, furniture, toys, and food in one store.

    Some people like the smaller stores of Greenwich Village or other areas when they are looking for an unusual present.

    Some streets have only one kind of stores. Bracelets (手镯) and rings shine in the windows of Canal Street, and wedding dresses fill the stores of Grant Street. There are streets for furs(皮大衣), and, in one area, there are 600 shops for antiques (古玩)! Fifth Avenue is the most famous place to shop, and it is usually the most expensive. There you can find the latest styles from Paris, Italy, or New York. You can spend thousands of dollars on Fifth Avenue, or you can just window shop and admire the sights for free.

    Last week, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon.

    Imagine never having to worry about traffic, stop lights, or road construction. A flying car would get to a place much faster than one travelling by road. On the other hand, imagine having to avoid drones (无人驾驶飞机) and other flying cars. Also, what if your battery dies when you are in the air? And, how will you know where to land?

    Kitty Hawk is a start-up tech company supported by Google co-founder, Larry Page. According to the Kitty Hawk website, its car will be able to travel at speeds up to 40 kilometers an hour in the air. It says under US aviation law such a machine “does not require registration or a pilot's license and may be flown in uncongested (不拥挤的) areas for recreational purposes.” As of now, the car can only be flown over fresh water.

    Kitty Hawk is making a list of people interested in buying the flying car. They must pay a deposit of US$100. Those who get their names on the list early will receive US$2, 000 off the final cost of the car. However, Kitty Hawk has not yet announced the price. Kitty Hawk expects its first flying cars will go on sale by the end of this year.

    At a conference last week, Uber announced plans for flying taxis to begin carrying passengers. Unlike the Kitty Hawk company, Uber does not plan to build its flying cars. Instead, it will use the resources of partner companies.

    Like the Kitty Hawk car, Uber flying taxis will use electric power. Uber says its flying taxis could travel up to 241 kilometers an hour. The company said that could reduce the travel time between San Francisco and San Jose, California from two hours on the road to 15 minutes in the air.

    Riders could use the Uber app to book a flying taxi to take them to their destinations. The company has not yet said how costly air taxi travel would be compared to road taxi travel.

    When you watch a movie these days, it's difficult to tell what's real and what's created by using computers. Visual effects can even change how movies are made.

    Almost anything that can be imagined by a director can now become reality in the world of movies. "We're really not limited by the technology, '' said David Smith, the CEO of Sony Pictures Imageworks. Mr Smith said that with today's technology, the digital world was more realistic than ever before. For The Amazing Spider-Man 2, Mr Smith's team created a Times Square that was exactly like the real one in New York. "If there are lights inside the stores that are lighting areas inside the store we put those lights there," said Mr Smith.

    But there was still one challenge for visual effects artists, said Paul Debevec of the University of Southern California Institute for Creative Technologies. "We're still trying to figure out how to perfect the human face in movies, " said Debevec. He said the movie — The Curious Case of Benjamin Button was still one of the best examples of computer generated movies, as actor Brad Pitt could be from an aged man to a baby in the movie.

    Mr Debevec added that besides changing the look of an actor's face, there could be another use for digital faces in the entertainment. Last year, effects artists created a digital face of the Asian pop singer Teresa Teng who was dead. Fans could still see and hear the concert on YouTube.

    Mr Debevec expects directors will start to use more virtual production techniques, like those seen in the movie Avatar. Mr Debevec says that with virtual production, there won't be a need for so many people behind the scenes. But visual effects artists agree, even with advanced technology, there is no replacement for a real actor showing a character in a movie.
