Salvador Dali (1904-1989) was one of the most popular modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L'Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist's showman qualities.

    The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.

    The exhibition shows how Dali draws the viewer between two infinities (无限). “From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,” explains the Pompidou Centre.

    The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg.

    People tend to become more personal and hide less of themselves when using email. Researchers from Open University in Britain have found in a recent study that there are good reasons for this.

    The team of researchers asked 83 pairs of students, all strangers to each other, to solve a problem. They had to discuss this question: If only five people in the world could be saved from a world disaster, who should they be? The pairs of students had to talk over the problem either face to face or by computers. Dr. Johnson said, “They told their partners four times as much about themselves when they talked over the Internet as when they talked face to face. When the computers were fitted with cameras so that students could see each other, this limited the personal side of the conversation.”

    Generally the information was not extremely personal. It was mainly about things such as where they went to school, or where they used to live. But some students discussed their love stories, and personal childhood experiences.

    Dr Johnson believes that emailing encourages people to focus on themselves. And when they do this, they become more open, especially if there are no cameras. “If you cannot see the other person, it becomes easier to talk about yourself. This is because you are not thinking what the other person is thinking of you. So emailing has become the modern way of talking,” said Dr. Johnson. However, this style of talking is not entirely new. “In the 19th century people started to use the ‘telegraph' to communicate. Now the same kind of thing has happened and people ended up speaking more freely.”

    Dr. Johnson thinks that emailers need to know about these effects of emailing, especially when they start work in a company. “ If you don't know about them, you could find yourself saying more about yourself than you wanted to.”

    It was with heavy hearts that my son and I worked to prepare his car for a milestone journey—the day he moved across the country after twenty years of living under my roof．

    Our work went slowly into the afternoon．The Sunday baseball game came on．Our hometown Cardinals were playing the Atlanta Braves．I overheard bits of the TV broadcast—Atlanta took a two-run lead as we were packing the trunk．After that I became absorbed in glum thoughts about his departure and forgot about the game．Suddenly I heard the door open．“Dad，”he said，“let's watch the game．They're only down by a run．”

    His red-colored eyes instantly told me that he，too，found this to be difficult and wanted to share one last father-son moment．Without hesitation I led the way to the TV set．There，we found the Cards losing 3—1．“Oh，”he said，“they're down two runs．”His voice cracked with doubt．“I thought they were coming back．”“That's fine，”I said，wanting so much to string this moment．“Let's watch anyway．”

    The Cards got to bat last．First a single，and then another．Suddenly the game became very interesting．When David Eckstein parked the third pitch(投球)into the seats，we were transformed，jumping up and down．That's when the magic moment came．The sadness of that day was replaced by the exciting baseball game，something we had done many times together before．

    Then he left．It was a sad day when I helped my son pack and get ready to move away to college．But this moment of joy mixed with sadness made the day，the trip and our life seem so right．

    We know that our pet dogs and cats can recognize our faces, but our pet fish? A team of scientists from the UK and Australia have discovered that archer-fish(喷水鱼) can distinguish human faces!

    This marks the first time that a species of fish has shown such an ability. Such abilities have been previously shown in birds, but unlike fish, they have been proven to possess structures similar to the neocortex(大脑新皮层), the researchers added.

    "Being able to distinguish between a large number of human faces is a surprisingly difficult task," Dr Newport said, "mainly due to the fact that all human faces share the same basic features."

    During their experiments, Dr Newport and her colleagues presented archerfish with two images of human faces, and trained them to choose one by spitting jets(喷射流)of water at that picture. Next, the fish were presented with the familiar face and several that were unfamiliar, and were able to correctly pick the one that they had been trained to recognize, even when features such as head shape and color were removed from the selected pictures.

    In the first experiment, the archerfish were tasked with picking the previously learned face from a group of 44 new ones, which they did with 81 percent accuracy. In the second, the researchers decided to make things a little harder. They took the pictures and made them black and white and evened out (使平均) the head shapes. You would think that would throw the fish for a loop. But no, they were able to pick the familiar face even then—and with more accuracy: 86%!

    "Fish have a simpler brain than humans and entirely lack the section of the brain that humans use for recognizing faces. Despite this, fish may still be capable of finding the face they are trained to recognize," Dr Newport said. "The fact that archerfish can learn this task suggests that complicated brains are not necessarily needed to recognize human faces."

    One cold morning in winter, I went alone to a hillside to do some hunting. I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me. There was no cover near him. Surely I could shoot him.

    To my surprise, he came toward me! He was curious, I suppose, or maybe he was stupid. For this was not a young deer, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers (鹿角) was clearly in sight.

    I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me.

What happened next was hard to believe. But it all seemed quite natural. I held out my hands and touched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head.

    I touched his head and body. His nose touched my shoulder. I fed him with my last sandwich.

    Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn't, either. Not after that. I just watched him go, a strong deer carrying a proud head.

    I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around.

    You will now understand why I gave up hunting from that day on.

    Why do we dream? It's a question researchers have been studying for years. Now new research suggests that some dreams may result from the brain's effort to keep learning, even as we sleep.

In a study in Boston,100 volunteers were trained for an hour on a maze(迷宫). They tried to find their way through the difficult puzzle as quickly as possible. Then half of the volunteers were allowed to sleep for 90 minutes. The other half stayed awake, reading or relaxing. The ones who slept were asked to describe their dreams when they woke up.

    After the rest, the volunteers were asked again to solve the maze. Those who hadn't slept showed no improvement or did even worse after the break. Sleepers who didn't report any maze­related dreams did better but showed only a little improvement. However, four nap­takers who reported dreaming about the maze showed a surprising improvement. They scored 10 times higher after sleeping and dreaming about the maze.

    Even though the number of dreamers was small, the researchers noted that the gap in learning between the dreamers and non­dreamers was so wide that the finding was significant(有意义的).

The dreamers had all performed poorly on the test before dreaming about it. That suggests that struggling with a task might be the trigger that leads the sleeping brain to focus on it and work on how to deal with it.

    "It's almost as if your brain is going through everything that happened today," Dr Stickgold, a scientist at Harvard Medical School, said. "The things you're obsessed(迷住) with are the ones that your brain forces you to continue to do with."
