    Look and listen, and that concert poster just might be singing. Engineers have designed antennas(天线)that can turn everyday objects, from posters to clothing, into radio stations. Anyone walking or driving by can tune in and hear what's on. The devices use radio waves, but they don't generate their own. They hijack(劫持)the same waves that carry music and news to your smartphone.

    Vikram Iyer co-led the project with Anran Wang, a graduate student in computer science and engineering. The two got the idea for their invention by paying attention to what was already around them. “It's the ideal way to minimize the power consumption for any kind of communication,” notes Iyer. Their research had focused on new types of wireless communications that won't require much energy. They wanted something that would work outdoors in a city. Then they realized the air is already filled with wireless communications in the form of radio stations.

    Radio waves carry energy at the speed of light from tall transmission towers to radios in cars, phones and homes. These waves of the antennas take in existing radio waves and change them slightly. Those changes add new sound information. The changed waves are then sent back out into the world where people can listen in. So the device only needs enough power to change the waves, not to generate them.

    The scientists tested their device with a poster. It advertised a Seattle concert by Simply Three. People standing almost 4 meters away from the poster could use FM receivers on smartphones to listen to all songs of the band's music. Those in cars as far as 18 meters away could use car radios to pick up some parts of the songs

    The technology could even extend to clothes. Iyer, Wang and their team turned the shirt into an antenna. It let the shirt talk to the wearer's smartphone. If a sensor in the shirt tracked a person's heart rate during exercise, for instance, the antenna could transmit those data to the wearer's phone.

    If you ask people to name the one person who had the greatest effect on the English language, you will get answers like "Shakespeare," "Samuel Johnson," and "Webster," but none of these men had any effect at all compared to a man who didn't even speak English-William the Conqueror.

    Before 1066, in the land we now call Great Britain lived peoples belonging to two major language groups. In the west-central region lived the Welsh, who spoke a Celtic language, and in the north lived the Scots, whose language, though not the same as Welsh, was also Celtic. In the rest of the country lived the Saxons, actually a mixture of Anglos, Saxons, and other Germanic and Nordic peoples, who spoke what we now call Anglo-Saxon (or Old English), a Germanic language. If this state of affairs had lasted, English today would be close to German.

    But this state of affairs did not last. In 1066 the Normans led by William defeated the Saxons and began their rule over England. For about a century, French became the official language of England while Old English became the language of peasants. As a result, English words of politics and the law come from French rather than German. In some cases, modem English even shows a distinction(区别)between upper-class French and lower-class Anglo-Saxon in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.

    When Americans visit Europe for the first time, they usually find Germany more "foreign" than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition.

    Researchers are looking into new ways to generate efficient photovoltaic energy (光伏能源) and for this they have been inspired by the v-shaped posture of the Cabbage White butterfly(菜粉蝶).

    Photovoltaic energy is the science behind solar power, where light is turned into electricity. It is a two-set process. Step one is a photoelectric effect, caused by sunlight. The second step is an electrochemical process, which generates an electric current.

    To improve the collection of sunlight, a research group has been inspired by the resting posture of the Cabbage White butterfly. The species has a natural range across Europe, Asia, and North Africa. To many farmers, the butterflies are regarded as a pest; to others, they are pretty to look at. To one research group the butterflies are an inspiration.

    The butterfly adopts a v-shape in order to heat up its flight muscles before taking off. By creating solar panels(太阳能电池板)in this formation,scientists think that the quantity of power that a solar panel can produce can be increased by around 50 percent.

    The Cabbage White butterfly is different to many other butterflies in using the v-formation. On cloudy days butterflies need to wait to receive enough sunlight in order to fly. However  by using the v-posture, the Cabbage White butterfly is able to take in more energy more quickly than other butterflies. In addition, the butterfly can reflect sunlight from its wings, which allows its flight muscles to be warmed to an ideal temperature.

    The new research was conducted at the University of Exeter's Environment and Sustainability Institute (ESI) and the Centre for Ecology and Conservation. Discussing the findings with Laboratory Manager magazine, lead researcher Professor Tapas Mallick stated :"Biomimicry(仿生学)in engineering is not new. However, this research shows pathways to develop low cost solar power that have not been done before. "

    The Origins of Famous Brands

    Our lives are full of brand names and trademarked products that we use every day. Although many brand names are simple acronyms(首字母缩略词) or versions of their founders' names, some of the companies we trust every day actually have fascinating and surprising back stories.

    Starbucks

    It seems fitting that the most famous coffee brand in the world would take its name from one of the world's greatest works of literature. The inspiration for the name of the coffeehouse came from Herman Melville's Moby Dick. The founders' original idea was to name the company after the Captain Ahab's ship — Pequot, but they eventually decided that Pequot wasn't a great name for coffee, so they chose Ahab's first mate, Starbucks, as the name instead.

    Nike

    Originally founded as a distributor for Japanese running shoes, the company was originally named BRS, or Blue Ribbon Sports. In 1971, BRS introduced its own soccer shoe, a model called Nike, which is also the name for the Greek goddess of victory. In 1978, the company officially renamed itself as Nike, Inc.

    The right name is essential to a company's success, and a great origin story is just as crucial as a great product. An attractive origin story is one more thing that keeps customers guessing, wondering, and buying its products.

    Google

    Google was originally called BackRub, for it searched for links in every corner of the Web. In 1997, when the founders of the company were searching for a new name showing a huge amount of data for their rapidly improving search technology, a friend suggested the word "googol". When a friend tried to register the new domain name, he misspelled "googol" as "google".
