What will you think of when it comes to “Hong Kong” and “great swimming”? Shopping sure, but swimming pool? Turns out, along with all its other attractions, Hong Kong is loaded with wonderful pools.

    The Ritz－Carlton

    The pool at the Ritz－Carlton is breathtaking, thanks to the view, the altitude and, of course, the swim. On the 118th floor at 484 meters above the street in the tallest building in Hong Kong, it's the world's highest swimming pool. The ceiling and walls are made up of 144 LED screens displaying coral reefs and other natural scenes.

    W Hotel Hong Kong

    If you have only one nice swimsuit, save it for the W Hotel Hong Kong. Only people living in this hotel can enjoy this wonderful pool, which is Hong Kong's highest rooftop pool. The hotel's signature WET deck is famous for stylish and occasionally wild poolside parties in summer. WET also features a good cocktail bar and a Jacuzzi.

    Hotel Indigo

    One of Hong Kong's unique experiences is swimming in Hotel Indigo's glass bottom pool. The pool protrudes from the hotel, allowing people below to see swimmers and the swimmers to do laps while checking out the traffic below. The pool is smaller compared to other local grand hotels and only available to the hotel guests.

    Four Seasons Hotel

    The Four Seasons Hotel gorgeous infinity pool overlooks Victoria Harbor. Even cooler, the hotel pipes in underwater music, making the swim much more wonderful, or annoying, depending on your taste in music. The pool is open only to hotel guests.

    Women make better drivers than men for many reasons. Why is that? If you ask me, I'd like to say, men know that women are better drivers but do not have the courage to admit the truth—women are queens of the road.

    Unlike men, women stop for directions when they have no idea as to where they are going. We don't drive around for hours pointlessly wasting a tank of gas only to find ourselves heading in the wrong direction. Have you ever been in a car with a man who is lost? He tells you to shut up when you begin to open your mouth. And every five minutes or so he takes a turn going forty-five miles per hour only to find out he's made another wrong turn.

    Speeding is what men do best on the road. There is a reason why men get more speeding tickets than women. Not because we trick to get out of tickets but only because we don't get pulled over as frequently. We don't speed. We have more intelligence than senselessly to put our own lives as well as the lives of others in danger.

    My largest issue with male drivers is how a majority of them drive with one hand on the wheel and the other hand doing only God knows what. The seat is backed as far as possible, and they're totally lost into loud music beyond a necessary level. You don't ever see women driving like that.

    I feel that the above evidence more than proves my points that women are not only better drivers but also safer drivers than men. We women rule the road. Oh, and men, if you want to continue criticizing（批评）women for being bad drivers, bring it on.

    Last summer I sat at a long picnic table near a breathtaking mountain. While the parents were eating dinner, the kids ran up a trail in search of a secret fort. Twenty minutes later one excited little boy, James, interrupted the adult conversation.

    “Mom, Mom, you can't believe what we found!”

    Lovingly, his mother smiled and whispered, “I can't wait to hear, James, but grown-ups are talking, and there will be a pause in the conversation. Please wait for the pause.”

    On my other side, another boy came running up to his mother with equal enthusiasm.

    “Mom, Mom, we had so much fun—”

    “I am talking! Don't interrupt,” she said.

    “But, Mom—”

    “Be quiet! Can't you see that I am talking?”

    “But Mom we found the—”

    “Shut up, Steve!” she yelled.

    My heart sank. I knew what was coming. James, on my right, patiently waited for the pause, enthusiasm still alive and well. Steve, on my left, walked away from the table, looking shamed, carrying with him stories of secret forts never to be shared.

    What markedly different messages to the child! “Wait for the pause” versus “Shut up” gets incorporated (包含)so differently into a child's developing sense of self.

    Harsh(刺耳的) words have bad effects. That's why I want you to promise to delete the phrases “Shame on you” or “You should be ashamed” from your vocabulary. I have seen countless patients whose parents' thoughtless words echoed in their heads and chipped(消除) away at their self-worth, even decades later.

    So we have to discipline ourselves to make our instructions constructive. One great tool is to look for positive behavior to reinforce. Don't ignore the things that your kids are doing right. Thank your children. Tell them that you noticed how they waited patiently or cleared their plate without being asked. Chances are that they will do it again. Let them feel noticed, appreciated, and valued. There's no better way to shape behavior.

    Palaces are known for their beauty and splendor, but they offer little protection against attacks. It is easy to defend a fortress (堡垒),but fortresses are not designed with the comfort of a king or queen in mind. When it comes to structures that are both majestic and well-defended, the classic European castle is the best example of design. Across the ages castles changed, developed, and eventually fell out of use, but they still command the fascination of our culture.

    Castles were originally built in England by Norman invaders. In 1066. As William the Conqueror advanced through England, he defended key positions to secure the land he had taken. The castles he built allowed the Norman lords to draw back to safety when threatened by English rebellion. Castles also served as bases of operation for offensive attacks. Troops were summoned to（召集）, organized around, and deployed (部署) from castles. In this way castles served both offensive and defensive roles in military operations.

    Not limited to military purposes, castles also served as offices from which the lord would administer control over his kingdom. That is to say, the lord of the land would hold court in his castle. Those that were socially beneath the lord would come to report the affairs of the lands that they governed and pay tribute to the lord. They would address conflicts, handle business, feast, and enjoy festivities, In this way castles served as important social centers in medieval England. Castles also served as symbols of power. Built on important and noticeable sites overlooking the surrounding areas, castles constantly appeared in the background of many peasants' lives and served as a daily reminder of the lords strength.

    Now, castles no longer serve their original purposes. However, the remaining castles receive millions of visitors each year from those who wish to experience the glory of a time long passed.

    When Oliver Sacks, 82, died on Aug 30 at his home in New York City, the world was saddened by the loss of a brilliant neurologist (神经学者)and a truly beautiful mind.

     London-born Sacks was most famous for his writing. A Forbes obituary (讣告)calls him "one of the greatest writers of science of the past 50 years. Maybe the greatest".

    In his best-selling 1985 book The Man Who Mistook His Wife far a Hat, Sacks described man who could not tell the difference between his wife's face and his hat, because his brain had difficulty telling what he saw.

    In 2006, Discover magazine ranked it among the 25 greatest science books of all time, declaring, "Lots of neuroscientists now looking into the mysteries of the human brain cite (列举)this book as their greatest inspiration."

     His 1973 book. Awakenings, is about a group of patients who were frozen in a decades-long sleep until Sacks tried a new treatment The book led to a 1990 movie in which Sacks by Robin Williams. It was nominated (提名)for Academy Awards.

    Another book. An Anthropologist on Man、published in 1995, described cases like that of a painter who lost his color vision in a car accident but found new creative power in black-and-white images. Sacks also wrote the story of 50-year-old man who suddenly regained sight after nearly a lifetime of blindness. The experience was a disaster. The man's brain could not make sense of the visual world. After a full and rich life as a blind person, he became "a very disabled and miserable (悲惨的）sighted man," Sacks wrote. "When he went blind again, he was rather glad of it."

    Despite the drama and unusual stories. Sacks' books were not meant to be freak shows. "Oliver Sacks humanizes illness…he writes of body and mind, and from every one of his case studies there shows a feeling of respect for the patient and for the illness," Roald Hoffinann, a Nobel Prize-winning chemist, said in 2001.

     When Sacks received the Lewis Thomas Prize for science writing in 2002, the citation (荣誉状)declare, "presses us to follow him into unknown areas of human experience and forces us to realize, once there, that we are facing only oureclves."

As far as we know batteries are playing an important role in our life. We couldn't live without batteries. Why so? Batteries provide power for anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

" To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU." The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."

Kwo n and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/ nanoelectromechanreal systems(M/NEMS). Although nuclear batteries can cause concerns, Kwon said, they are safe.

" People bear the word‘ nuclear' and think of something very dangerous," he said," However, nuclear power sources have already been safely powering a variety of devices, such as pace- makers, space satellites and underwater systems."

His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

" The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor, Kwo n said," By using a liquid semiconductor, we believe we can minimize that problem."

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwo n is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwo n said that battery could be thinner than the thickness of human hair.
