The Greatest Navigational Journey

    In 1787 Captain Bligh was given command of “The Bounty”, a three-year-old merchant ship. His mission was to transport breadfruit plants from the island of Tahiti to the West Indies. We know the popular story of this voyage and the rebellion, in which Bligh has been presented as hard, violent and thoroughly unpleasant captain. However, there is quite a lot of evidence to suggest that this picture is far from being true. He seems to have been unusually thoughtful about the health and welfare of his men. For example he made sure that his crew got exercise, insisted on cleanliness on his ship, and adopted the practice of giving them a drink which prevented scurvy every day.

    When Captain Bligh arrived in Tahiti, it became clear that it would be some months before the breadfruit trees were ready to be taken to the West Indies. Instead of going off right away, he gave his crew extended shore leave. This may have been a mistake as many were unhappy about leaving when the time came. Finally, on the return journey the rebellion took place. The ship was under the command of the rebels and Captain Bligh had to leave in a small boat.

    Captain Bligh's achievement was to get to dry land successfully. It is one of the supreme examples of seamanship. Apart from Bligh there were 18 members of his crew sailing in an open boat about 23 feet long and 7 feet wide. They took with them 25 gallons of water, 150 pounds of bread and 30 pounds of pork. They had no guns or other weapons. The boat was so low in the water that it seemed likely to sink at any time. On one occasion Captain Bligh tried to land on an island to get more water. He and his men were attacked by hostile natives and one of the crew was killed. At this point Bligh decided to sail directly to the Dutch settlement on the island of Timor without stopping. The distance was about 4,000 miles. The voyage took about 42 days and he had no advanced navigational equipment. However, his skill and commitment proved equal to the task and amazingly no one else died. It was truly a remarkable achievement.

    When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

    What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.

    Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

    What's more exciting than having a fresh hot pizza delivered to your door?  How about having it brought to you by a robot?  Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

    The fully autonomous DRU is the result of cooperation between Domino's Pizza Australia and Marathon Robotics. The 450-pound machine that travels at a maximum speed of 12. 4 miles an hour can traverse a distance of up to 12 miles and back, before requiring to recharge the battery. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.

    The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders. To access their food, customers have to enter the unique code provided for them by the company. This not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

    Scientists expect additional DRU's to be ready for service in their various Queensland locations within the next six months. But don't expect these super cute robots to replace humans anytime soon. According to Domino's the DRU still needs extensive testing, which the company believes could take up to two years.

    And then there is also the issue of regulations. The public use of autonomous vehicles is still banned in most countries. But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried. He is“confident that one day DRU will become an integral part of the Domino's family. ”

    My friend, Jack, was a taxi driver. We became friends quite by accident. Five years ago, I made a trip to Chicago. The moment I stepped into a cab, I realized it was different. The floor was covered with a rug (小地毯). There were small reproductions of paintings by Van Gogh inside the cab. And the windows were spotless. I told the driver I had never ridden in a more attractive taxi.

    "I like to hear my passengers say that," he replied. "How long have you been decorating your cab?" I asked. "It's not mine," he said. "It's a company cab. I hit upon the idea years ago when I worked as a clean-up man for the taxi company. Each car that came in at the end of the day was like a garbage pit. Cigarette butts and matches covered the floor. Sticky stuff like peanut butter was on the seats or door handles. I thought that if the company and the drivers would give people a car worth keeping clean, they might be more considerate."

    "As soon as I got my taxi license, I tried out my ideas. I put a lot of extra decorations into the cab they gave me to drive. I got a nice rug and some flowers. When each passenger got out, I checked to make sure that everything was in order for the next fare. After about a month of my bringing in a spotless cab, the boss reserved the same car for me each day. That was when I put up the reproductions of great paintings."

    "I've never been disappointed by people in the past ten years—no garbage. Like I say, people appreciate beautiful things. If we planted more flowers and trees in the city and made the buildings more attractive, more people would tend to keep the city clean."

    Later, we became good friends. I was impressed by the taxi-driver, who had hit on a great truth—a sense of beauty comes with the gift of life. Most people don't have to be instructed about the rarity of beauty. They respond when they find it. And, if they are made to feel a part of it, they will try to add to it.

    Sure, it's good to get along with your teacher because it makes the time you spend in the classroom more pleasant.

    And yes, it's good to get along with your teacher because, in general, it's smart to learn how to understand the different types of people you'll meet throughout your life

    "But really, there's one super-important reason why you should get along with your teacher. When you do, learning bursts right open," says Evelyn Vuko, a longtime teacher who writes an education column (专栏) called "Teacher Says" for the Washington Post newspaper.

    In fact, kids who get along with their teachers not only learn more, but they're more comfortable asking questions and getting extra help. This makes it easier to understand new material and do your best on tests. When you have this kind of relationship with a teacher, he or she can be someone to turn to with problems, such as problems with learning or school life like bullying.

    As a kid in a primary or middle school, you're at a wonderful stage in your life. You're like a sponge(海绵), able to absorb lots of new and exciting information. On top of that, you're able to think about all this information in new ways. Your teacher knows that, and, in most cases, is very excited to be the person who's giving you all that material and helping you make it. Remember, teachers are people, too, and they feel great if you're open to what they're teaching you. That's why they wanted to be teachers in the first place—to teach!

    Some kids may be able to learn in any situation, whether they like the teacher or not. But most kids are sensitive to the way they get along with the teacher, and if things aren't going well, they won't learn as well and won't enjoy being in class.

    I don't think I can recall a time when I wasn't aware of the beauty of the ocean. Growing up in Australia, I had the good fortune of having the sea at my side. The first time I went to Halfmoon Bay, I suddenly had the feeling of not being able to feel the ground with my feet anymore.

    For my 10th birthday, my sister and I were taken out to the Great Barrier Reef. There were fish in different colors, caves and layers of coral. They made such an impression on me. When I learned that only 1 percent of Australian's Coral Sea was protected, I was shocked. Australian marine life is particularly important because the reefs have more marine species than any other country on earth. But sadly, only 45 percent of the world's reefs are considered healthy.

    This statistic is depressing, so it's important for us to do everything to protect them. The hope that the Coral Sea remains a complete eco-system has led me to take action. I've become involved with the Protect Our Coral Sea activity, which aims to create the largest marine park in the world. It would serve as a place where the ocean's species will all have a safe place forever.

    Together, Angus and I created a little video and we hope it will inspire people to be a part of the movement. Angus also shares many beautiful childhood memories of the ocean as a young boy, who grew up sailing, admiring the beauty of the ocean, and trying to find the secrets of ocean species.
