China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    When thinking about placing a human being in space, one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment. The cold of space will freeze skin in a short time. The fierce heat of the sun can cause serious burns. The lack of atmosphere can cause gases in the body to expand(扩大) and even burst. With no oxygen to breathe, a human being will die in only a few moments. Radiation from the sun is another risk in space. So is damage from small pieces of rock and objects like meteoroids (陨石).

    In 1933, an American flyer, Wiley Post, designed one of the first successful devices to protect a pilot at extreme heights. It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.

    Today, astronauts wear very different protective clothing. It lets them move, do useful tasks, and stay outside their spacecraft in comfort and safety for several hours. The spacesuit is called the shuttle extravehicular mobility unit or EMU. It was designed to endure longer and to permit more movement than earlier spacesuits.

    The EMU has a number of parts that an astronaut can link together by using only one hand, which makes it possible for each astronaut to select the parts that fit correctly.

    Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.

    Most people, when they travel to space, would like to stay in orbit (轨道) for a few days or more. And this stands to reason, if you're paying $ 20,000 for your trip to orbit! So in order for tourism to reach its full potential there's going to be a need for space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel—private rooms, meals, bars. But they'll also offer two unique experiences: impressive views—of Earth and space—and the endless entertainment of living in zero gravity—including sports and other activities that make use of this.

    The hotels themselves will vary greatly—from being quite simple in the early days to huge luxury (奢侈的) structures at a later date. It's actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven't expected the costs to come down far enough to make them possible.

    Lots of people who've been to space have described vividly what it's like to live in zero gravity. There are obviously all sorts of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don't need to sleep much living in zero gravity, so you'll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below.

    Of course all good things have come to an end, unfortunately. And so after a few days you'll find yourself heading back to the earth. You'll be thinking how soon you can save up enough to get back up again-or maybe you should change jobs to get to work in an orbiting hotel!

    When you choose a friend, you should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair weather friends. They will be with you as long as you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities of character, especially understanding, honesty and reliability (可靠).

    Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener.

    At the same time, however, a good friend is honest. He does not look for faults (过错) in others. He notices their good points. In short, good friends will be honest to each other and accept each other.

    Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor, he will do his best to help me. If I am in trouble, he will not run away from me.

    There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience and learn from each other. A good friend has a good sense of humor, too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

    When I meet someone who is reliable, honest, and understanding, I know I've found a friend!

    No one has a temper naturally so good, that it does not need attention and cultivation, and no one has a temper so bad, but that, by proper culture, it may become pleasant. One of the best disciplined tempers ever seen, was that of a gentleman who was naturally quick, irritable, rash, and violent; but, by taking care of the sick, and especially of mentally deranged (疯狂的) people, he so completely mastered himself that he was never known to be thrown off his guard.

    There is no misery so constant, so upsetting, and so intolerable to others, as that of having a character which is your master. There are comers at every tum in life, against which we may run, and at which we may break out in impatience, if we choose.

    Look at Roger Sherman, who rose from a humble(低下的) occupation to a seat in the first Congress of the United States, and whose judgment was received with great respect by that body of distinguished men. He made himself master of his temper and cultivated it as a great business in life. There are one or two instances which show this part of his character in a light that is beautiful.

    One day, after having received his highest honors, he was sitting and reading in his sitting room. A student, in a room close by, held a mirror in such a position as to pour the reflected rays of the sun directly in Mr. Sherman's face. He moved his chair, and the thing was repeated. A third time the chair was moved, but the mirror still reflected the sun in his eyes. He laid aside his book, went to the window, and many witnesses of the rude behavior expected to see the ungentlemanly student severely punished. He raised the window gently, and then-shut the window blind(百叶窗)!

    I can not help providing another instance of the power he had acquired over himself. He was naturally possessed of strong passions, but over these he at length obtained an extraordinary control. He became habitually calm and self-possessed. Mr. Sherman was one of those men who are not ashamed to maintain the forms of religion in their families. One morning he called them all together as usual to lead them in prayer to God. The "old family Bible "was brought out and laid on the table.

    Mr. Sherman took his seat and placed beside one of his children. The rest of the family were seated around the room, several of whom were now grown ups. Besides these, some of the tutors of the college were boarders in the family and were present at the time. His aged mother occupied a corner of the room, opposite the place where the distinguished Judge sat.

    At length, he opened the Bible and began to read. The child who was seated beside him made some little disturbance, upon which Mr. Sherman paused and told him to be still. Again he continued but again he had to pause to scold the little offender, whose playful character would hardly permit it to be still. At this time he gently tapped its ear. The blow, if blow it might be called, caught the attention of his aged mother, who now with some effort rose from the seat and tottered across the room. At length, she reached the chair of Mr. Sherman, and in a moment, most unexpectedly to him, she gave him a blow on the ear with all the force she could gather. “There, "said she, "you strike your child, and I will strike mine.”

    For a moment, the blood was seen mounting to the face of Mr Sherman. But it was only for a moment and all was calm and mild as usual. He paused; he raised his glasses; he cast his eye upon his mother; again it fell upon the book from which he had been reading. Not a word escaped him; but again he calmly pursued the service, and soon sought in prayer an ability to set an example before his household which should be worthy of their imitation. Such a victory was worth more than the proudest one ever achieved on the field of battle.

    Check out our tsunami (海啸) facts and lean some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some notable recent examples of tsunamis that have occurred around the globe.

    Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions.

    As a tsunami approaches the shore, water may move back from the coast. If it is shallow enough, the water may be pulled back hundreds of meters. If you are in the area, observing this is a good indication that a tsunami is on the way.

    Regions in tsunami danger zones often have warning systems in place to give people as much time to evacuate (撤离) as possible.

    When tsunamis hit shallow water (often near the coast), they slow down but increase in height.

    An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200, 000 people in 14 countries.

    In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15, 000 people.

    The tsunami waves created by the Tohoku earthquake reached heights of over 40 metres (131feet) in mine areas, wiping out coastal towns and causing a number of nuclear accidents.

    The Japanese word "tsunami" literally means "harbour wave".

    Tsunamis are sometimes referred to as tidal waves but this term has fallen out of favour because tsunamis are not related to tides.
