Salvador Dali (1904-1989) was one of the most popular of modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L'Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist's showman qualities.

        The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.

        The exhibition shows how Dali draws the viewer between two infinities (无限). “From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,” explains the Pompidou Centre.

        The fine selection of the major works was done in close collaboration (合作)with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg, Florida.

    The holiday season isn't just about shopping and gifts. {#blank#}1{#/blank#} However, holiday travel can be more expensive than the gifts. Fortunately, the following tips will help keep your travel spending under control.

● Plan ahead. The earlier you book your travel, from airfare to hotels, the easier it is to find good deals. {#blank#}2{#/blank#} Your best prices on airfare come when you book three weeks before the plane leaves for domestic flights. For international flights, consider booking 30 days in advance. Many experts point out that you should book travel between  one month and three months out for high-traffic holidays.

● Book your air travel on cheaper days. Traveling by air on Tuesdays and Wednesdays often costs less than traveling on Fridays and Sundays. During the holidays, it is not just about a specific day of the week. You also need to consider the days surrounding the holiday but days immediately before and after a holiday can be expensive. One of the best ways to save is to plan your air travel on the Day of the holiday. {#blank#}3{#/blank#}

● Consider traveling overnight. Red-eye flights and overnight flights often cost less than those at more convenient times. {#blank#}4{#/blank#}Traveling overnight can help you avoid a night in the hotel, as well as save your money on travel to your destination.

●{#blank#}5{#/blank#} You can't bring liquids with you on the airline, but you can bring sandwiches and other snacks. When you are on the road, you can buy food at local groceries to make your own meals. If you are staying in a hotel long-term, consider cooking your own food, especially if you have access to a microwave.

    Well-known for historic architecture and chocolates, Lviv, Ukraine's official capital of culture, looks, smells, and tastes like the best of Europe. Indeed, its western flavor has earned it the title "Little Paris of Ukraine".

    For centuries Lviv, located 50 kilometers from the Poland-Ukraine border, was an important stopping point on the main trade routes between the east and west. During the Renaissance, the city could afford Italy's finest architects because every merchant passing through was forced to stay and sell their goods for at least two weeks. "It was a very smart move to collect money from them," said Yaroslav Hrytsak, a local historian, adding, "It kept the wealth in the city, and that wealth has been transformed into architectural richness."

    Many historic buildings remain but Lviv's prosperity didn't survive its bloody history. Over the centuries, the city fell under the rule of Poland, Austria, Austria-Hungary, Russia and the Nazi Germany. In addition, both Sweden and Turkey tried unsuccessfully to conquer the city. Then for almost half a century Lviv was ruled by the Soviet Union (苏联). With that, the city was condemned to relative obscurity(无闻). But recently things have started to change. Lviv experienced a sudden 40% increase in tourism in early2010, which was the highest rate in Europe. Just last month, its gates opened even wider, when Lviv became a host city for the Euro 2012 football championships.

    So how has this happened? With the Soviet collapse, some saw new opportunities for reviving Lviv's former wealth and fame.

    Limelight networks is a US-founded company. It's one of many digital tech firms to have opened offices in Lviv over the past few years. "It had good growth and experience in the US, however, the company needs more talent to do the new cool projects and products for our customers. This is why we're here in Ukraine." said CEO of Limelight networks.

    Lviv's unexpected abundance of I.T. talent is in fact a legacy(遗产) of the former Soviet Union. To help the military, many Soviet universities focused on turning out world-class engineers and Lviv's university is still producing them. Now, the city is home to 23 higher education institutions. It's clear that the city of Lviv does not intend to remain a hidden jewel for much longer.

    There are an unbelievable number of reasons to go to Greece; just like there are an unbelievable number of things to do once a traveler arrives there. Here is a look at just some of the great historical things to see when on holiday in Athens, Greece.

    Agora

    Agora lies in ruins now, but during its glory days it was a lively and active open marketplace where Greeks came to buy, sell, and exchange their goods and services. Agora has ties to common people of ancient Greece.  Guided tours are available and there is also a small museum with many artifacts from this area on display.

    Parthenon

    One of the most famous landmarks in Athens is the legendary Parthenon. This building is still today admired by architects who are appreciative of the decorative design, as well as the engineering involved in its construction.  Those interested in history will be impressed beyond belief with the opportunity to see this historic structure up close and personal.

    Temple of Olympian Zeus

    One of the most impressive monuments to see up close is the Temple of Olympian Zeus. Many people see this monument from far away, or even from the window of a taxi, and never stop for a first hand look themselves. This is a huge mistake as the size of it cannot truly be appreciated without visiting it up close.

    Odeum of Herodes Atticus

    Built into the hillside and providing a nice view of Athens is the Odeum of Herodes Atticus. This theater was constructed in the second century and was an important gathering place for both the upper and lower classes. It holds a little over 5,000 people, is located just below the Acropolis, and is still used for performances to this day.

    A recent study finds that the dirt on the ground is likely to worsen climate change. Researchers have shown that warmer temperatures are heating the soil, which is causing microbes (微生物) to become more active and release more of the soil's carbon into the atmosphere. These soil changes can potentially contribute to even higher temperatures.

    Scientists studied device readings, soil measurements, plant growth details and satellite observations from around the world. Their work is the most complete study on the subject.

    They found a sharp increase in carbon released into the atmosphere by bacteria and fungi (真菌) in soil from 1990 to 2014. Researchers explain that the carbon comes from the dead plants and leaves the microbes eat. As temperatures rise, the microbes eat more. And the more they eat, the more carbon can be made into carbon dioxide and released into the atmosphere.

    This uncontrolled cycle speeds up and intensifies climate change. Overall, soil releases about nine times more carbon than human activities. But that is part of a natural cycle: the amount of carbon released into the air is about equal to the carbon oceans and plants take in.

    However, carbon released from fossil fuel causes an imbalance. Burning coal, oil and natural gas puts more carbon into the atmosphere than nature can take in. The additional carbon heats the air and soil. And as the air and soil get hotter, the earth will release more carbon than it has been holding.

    If something isn't done, we are really in trouble. Proper soil conservation can help keep more carbon in soil. Conservation methods include avoiding turning the soil, covering off-season crops and leaving crop deposits on the ground.

The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules.

The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste.

Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides.

Household food waste, which is translated to "wet trash" in Chinese, refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers.

Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste.

The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category.

As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash.

"We should do this from a pig's angle," commented one netizen. "Those edible (可食用的) for pigs are household food waste. Those even pigs don't want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste." The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200.
