Nikola Tesla

    Long overshadowed in public memory by his one-time employer, Thomas Edison, Tesla (1856—1943) was a brilliant scientist and engineer who earned more than 700 patents. He is most famous for developing alternating current (交流电), but his work also led to advances in wireless communications, lasers, X-rays, radar, lighting, robotics, and much more.

    Tesla was born to Serbian parents in what is now Croatia, but he emigrated(移民) to the U.S. as a young man, where he eventually became a naturalized citizen. Besides Edison, who later became his bitter rival, Tesla often worked with inventor George Westinghouse. In 1893, the pair demonstrated their advances in lighting and motors in the "White City" at the Chicago World's Fair. In 1895, Tesla and Westinghouse developed the world's first hydroelectric power plant, at Niagara Falls.

    At the turn of the century, Tesla set up a laboratory called Wardenclyffe in the small community of Shoreham, Long Island, where he conducted some of his most ambitious experiments. The building was financed by J. P. Morgan and designed by acclaimed architect Stanford White.

    The most prominent feature was Wardenclyffe Tower, also called Tesla Tower, a 187-foot-tall metal lattice tower topped with a big antenna that was intended to beam communications and even energy across the Atlantic.Tesla ran out of money while building the tower and was foreclosed(取消赎回权) on twice. As with his previous Colorado Springs lab, assets were sold to pay up his debts. In 1917, the U.S. government blew up the tower, fearing that German spies were using it in World War I. The metal was sold for scrap. For decades, the building was used for photo processing.

    "The tower is long gone, but the three-quarter-length statue of Tesla unveiled last week is a fitting memorial," said Alcorn, a retired teacher. "This is the last remaining Tesla laboratory anywhere in the world," she said. "He inspires those who work hard but don't get recognition, and people are starting to recognize how important his contributions are."

    As a sign of that growing appreciation, Elon Musk's start-up electric car company Tesla Motors was named after the visionary inventor in 2003.

    Japan has long been known for both its strong traditions and being on the cutting edge of technology, and this new inn combining the classic Japanese surroundings with high-tech slippers and furniture is a perfect reflection of this.

    Nissan Motor Co. developed a system in which slippers park themselves at the entrance of the traditional inn, called “ProPilot Park Ryokan,” waiting for guests to use them upon arrival. When guests have finished using them, the slippers will drive themselves back to their original position. Each slipper features two tiny wheels, a motor, and sensors to drive it across the wooden floor.

    The same technology features in Nissan's all-battery electric Leaf car. High-tech sensors and cameras allow the vehicle to safely back into parking spaces without any input from the driver. Four cameras and 12 sensors assess the vehicle's surroundings. ProPilot Park handles the accelerator, braking and steering (转向) input when the car is parking. Drivers operate the system with the press of a button, which they must hold down the entire time. Lifting a finger off the button will result in the car stopping immediately.

    The inn, located in the resort town of Hakone, about 75 kilometers southwest of Tokyo, is currently most famous for its view of Mount Fuji. However, the new self-driving slippers, released by Nissan in March, is the unique feature of the high-tech inn.

    “The self-parking slippers are meant to raise awareness of automated driving technologies, and their potential, non-driving applications,” Nissan spokesman Nick Maxfield said in a statement.

    In addition to the slippers, office chairs, floor cushions and traditional low tables in the inn also wheel themselves back into place after use.

    A child who suffers bullying (霸凌) usually has low self-respect and their ability to learn and be successful at school is greatly lessened. Therefore, bullying must be stopped.

    The best and most obvious way to stop bullying in schools is for parents to change the way they treat their children at home. Of course, this is much easier said than done and everyone treats their children differently. Bullies, however, come from homes where physical punishment is used and children have been taught that physical violence is the way to handle problems and “get their way”. Bullies usually also come from homes where the parents fight a lot, so they have been modeled on such violence. Parental involvement is often lacking in bullies' lives and there seems to be little warmth.

    Early intervention (干预) is truly the best way to stop bullying, but parents of the victims or therapists (治疗师) cannot alter the bully's home environment. Some things can be done at the school level, however.

    Most school programs that address bullying use a multi-faceted (多方面的) method to the problem. This usually involves the advice of some sort, either by peers, a school adviser, teachers, or the principal.

    Hand out questionnaires to all students and teachers and discuss if bullying is occurring. Define exactly what constitutes (构成) bullying at school. The questionnaire is a wonderful tool that allows the school to see how widespread bullying is and what forms it is taking. It is a good way to start to solve the problem.

    Get the children's parents involved in a bullying program. If parents of the bullies and the victims are not aware of what is going on at school, then the whole bullying program will not be effective. Stopping bullying in school takes teamwork and concentrated effort on everyone's part. Bullying also should be discussed during parent-teacher conferences and PTA meetings. Parental awareness is the key.

    In the classroom setting, all teachers should work with the students on bullying. Oftentimes even the teacher is being bullied in the classroom and a program should be set up to teach about bullying. Children understand modeling behaviors and role-play and acting out bullying situations is a very effective tool. Have students role-play a bullying situation.

    For many years, machines have been doing work that people once did, including some difficult jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings: the restaurant industry.

    Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from R. O. Korea and its robot, called DRC-Hubo, won first place in the competition. The second and third place finishers were from the United States.

    The robots were required to drive a vehicle, climb up steps and do mechanical work. Such activities are easy for humans to perform, but more difficult for machines.

    Not all of the competitors were successful. The failures showed how difficult it is to design effective walking machines.

    Recently, crowds gathered for the food machinery and technology show in Tokyo, Japan. They witnessed a robotic chef preparing food. Other machines cooked, baked tasty pastries and even made sushi.

    Akihiro Suzuki works at Yaskawa Electric, a company that develops robots. He says robots cannot do everything a human can, but they are able to work without becoming tired.

    He says robots cannot taste food, change heating levels or seasonings to get the best flavor. But he says if a food can be easily prepared, a robot can repeat the same movement to reproduce the same meal.

    One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery demonstrated its sushi maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi, but there are not enough skilled workers to prepare for it. He says his machine can help anyone make sushi.

    I was having a great morning until I sat down in front of my office computer. "Your password has expired(过期)," a server message flashed on my screen, with instructions for changing it.

    Coming up with a new code doesn't seem like a big deal, unless you work at my company, where we have to change it monthly, using at least one uppercase character, one lowercase character, one symbol, and one numeral. Oh, and the whole darn thing can't be fewer than eight characters. And I can't use any of the same passwords I've used in the past three months.

    Suddenly I was furious. What didn't make it any better was that I was deeply depressed after my recent divorce. Disbelief over what she had done to me was all I thought about. Every day.

    My anger didn't mean anything to the empty input field with a pulsating cursor (闪动的光标), waiting for me to type a password that I'd have to re-enter — many times — for the next 30 days. I remembered a tip I'd heard from my former boss. He'd said, "I'm going to use a password to change my life."

    I couldn't focus on getting things done in my current mood. There were clear indicators of what I needed to do to regain control of my life, but I couldn't notice them.

    My password became the indicator. My password reminded me that I shouldn't let myself be a victim of my recent breakup and that I was strong enough to do something about it.

    I made my password Forgive@h3r.

    I had to type this statement several times a day. Each time my computer would lock. Each time my screen saver with her photo would appear. Each time I would come back from eating lunch alone. In my mind, I wrote Forgive her every day.

    The simple action changed the way I looked at my ex-wife. That constant reminder of reconciliation led me to accept the way things had happened at the end of my marriage and embrace a new way of dealing with my depression. As the month wore on, I felt a slow healing begin to take place. By the time my server prompted me to reset my password the following month, I felt free.

    One month later, my dear Exchange server asked me yet again to reset my password. I thought about the next thing that I had to get done.

    My password became Quit@smoking4ever.

    I quit smoking overnight. This password was a painful one to type during that month, but doing it helped me to yell at myself in my mind as I typed that statement. It motivated me to follow my monthly goal.

    One month later, my password became Save4trip@thailand.

    Guess where I went three months later: Thailand.

    Seeing how these reminders helped to materialize my goals kept me motivated and excited. While it's sometimes difficult to come up with your next goal, keeping at it brings great results.

    Here is a simplified extract of what some of my passwords have been in the past two years, so you get an idea of how my life has changed, thanks to this method:

    Forgive@h3r To my ex-wife, who started it all.

    Quit@smoking4ever it worked.

    Save4trip@thailand it worked.

    Eat2times@day it never worked, still fat.

    Sleep@before12 it worked.

    Ask@her4date it worked. I fell in love again.

    No@drinking2months it worked. I feel better.

    Get@c4t! It worked. I have a beautiful cat.

    MovE@togeth3r it worked.

    Facetime2mom@sunday it worked. I talk with Mom every week.

    And the one for last month: Save4@ring Yep. Life is gonna change again soon.

    What do you want to be when you grow up? A teacher? A doctor? How about an ice-cream taster?

    Yes, there really is a job where you can get paid to taste ice cream. Just ask John Harrison, an "Official Taste Tester" for the past 21 years. Testing helps producers to be sure of a product's quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream –as well as for developing over 75 flavors(味道).

    Some people think that it would be easy to do this job; after all, you just have to like ice cream, right? No –-- there's more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this "cool" field.

    In a typical morning on the job, Harrison tastes and rates 60 ice-cream samples. He lets the ice cream warm up to about 12 F. Harrisonexplains, "You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup."

    While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. "Tasting begins with the eyes," he explains. He checks to see if the ice cream is attractive and asks himself, "Does the product have the colour expected from that flavor?" Next it's time to taste!

    Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy – working at once cool job.
