I was very disappointed not to be able to go to the jazz concert last Friday. The advertisement in the paper said that you could buy tickets at the theatre box in Richland Hills any day between 10:00 and 4:00. Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break.

    Unfortunately, the theatre is on theother side of the town, and the bus service between my office and Richland Hills is not very good. Butif you are lucky, you can make the round trip in 45 minutes. Last Monday, Istood at the bus stop for 15 minutes waiting for the bus, By the time I saw onecome around the corner, there was not enough time left to make the trip.

     So I gave up and went back to the office. The same thing happened on Tuesday, and again next day. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in exactly 20 minutes. When I got there, however, I found along line of people at the box office, I heard one man say he had been waitingin line for over an hour. Realizing I would not have enough timeto wait in line. I caught the next bus and headed back across the town.

    By Friday I realized my only hope was tomake the trip by taxi, it was expensive, but I felt it would be worth it tohear the concert. The trip by taxi only took 10 minutes, but felt like an hour to me. When I got to the theatre, I was relieved to see that nobody was waiting in line. The reason, however, I quickly discovered, was that they had already sold all the tickets.

    When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.

    Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.

    “This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.

    As for the Locata's correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.

    The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata's signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK' s General Lighthouse Authorities.

    Locata's technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

    It's not often you get information about a destination from a heavy metal band, but in Debrecen, Hungary's second largest city, locals are used to having to make a noise to get heard.

    Just off the historic center, Roncs bar is a pub that also hosts live music.  It has the atmosphere of a student party in an old building that might soon be knocked down.

    Roncs is owned by Hungary's best-known heavy metal rock band, Tankcsapda. Sometimes referred to as the “Hungarian Metallica", the band has taken a type of music that is famous worldwide and-through lyrics, album covers, and an annual New Year's party and concert-made it all about their home city.

    It's perhaps fitting that Tankcsapda should be seen as ambassadors for Debrecen-the city sometimes needs loud heavy metal rock music to get noticed. “Foreigners think that Hungary is Budapest and there's nothing else,” is a familiar saying on Debrecen's:streets.

    Debrecen has, at times, been more important than the current seat of power, with locals claiming it takes over in times of trouble.

    That doesn't quite add up.

    Debrecen survived an attack from the Mongols in the 13th century, the Black Death, 150 years of struggle against the Ottomans and numerous conflicts, and yet it has still only briefly been the country's capital twice. This happened for the first time after a short-lived revolution in 1849, and for a second time at the end of World War II.

    Today, Debrecen may not be well known to tourists, but that only adds to the charm of this relaxed city. It's a small place; the historical center is sized for strolling (散步) and regular cafe stops. There's also a view of Debrecen's mix of architectural styles, a result of the frequent large fires that back in the 19th century led the city's students to form one of Europe's first-ever fire brigades (消防队).

    You can also see traditional weathercocks from the rooftops, featuring Islamic star and crescent moon symbols that once advertised to Ottoman invaders that the city preferred trading to fighting.

    Trade meant that Debrecen's skilled people became very successful and the city became famous for-among other things-fine foods, hats and clay pipes. In the early 19th century, 10 million clay pipes were reportedly made a year, with thousands bought for Britain's navy.

    A new collection of photos brings an unsuccessful Antarctic voyage back to life. Frank Hurley's pictures would be outstanding — undoubtedly first-rate photo-journalism — if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous ship wreck (海滩) by a cameraman who had no reasonable expectation of survival Many of the images were stored in an ice chest under freezing water, in the damaged wooden ship.

    The ship was the Endurance a small tight Norwegian-built three-master that was intended to take Sir Ermest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica's Weddell Sm. From that point Shackleton wanted to force a passage by dog sled across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.

    As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance、adventuring was then a thoroughly commercial effort Scott's last journey, completed as he lay in a tent dying of cold and hunger, caught the world's imagination, and a film made in his honor drew crowds Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908,started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley，a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images most of which have never before been published.
