James Cook, at the age of forty, was sent by England to explore the Pacific Ocean. On his third voyage, as captain in charge of two ships, the Discovery and the Revolution, he came upon a group of unknown islands which he named the Sandwich Islands after his friend, the Earl (伯爵) of Sandwich. Today the islands are known at the Hawaiian Islands.

    When Cook sailed into a protected bay (海湾) of one of the larger islands, the natives greeted him with curiosity and respect. Some historians said that the islanders welcomed him, believing he was the god, protector of peace and agriculture.

    The islanders were short, strong people with a very well-organized social system. The men fished and raised crops. The women prepared for the children and made clothing for the men and short skirts for the women.

    We Travel in Our Minds

    What: This exhibition of sculpture aims to present ideas of theatricality, the fantastical, travel and exchange, with figures that take the forms of humans and animals. Made by artist Ethan Murrow, a professor at the School of the Museum of Fine Arts at Tufts University in Boston, these dream-like objects are inspired by puppetry (木偶戏), music, trade, navigation and beyond, with mixed effects of materiality, sound and imagination.

    Where: Duddell's, Level 3, Shanghai Tang Mansion, 1 Duddell Street, Central

When: Until March 10, 2019

    A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.

    Shining iridescent color, which changes depending on the angle from which it's viewed, is favored by everything from birds to beetles and blossoms to butterflies.

    "And in our research group we are of course interested in why this vivid metallic color is so widespread in nature." Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. " Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates."  But iridescence also shows up in situations where reproduction is not an issue. " So what we are studying now is whether natural selection imposed by predation(捕食行为) could explain the occurrence of iridescence in prey animals."

    The idea that eye­catching colors could be used as a cover­up isn't a new one." The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing­Coloration in the Animal Kingdom, already in 1909, that 'brilliantly changeable or metallic colors are among the strongest factors in an animal's concealment'. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal's concealment？"

    "In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition." Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. "It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish." As for making use of this method for hiding in plain sight, "Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize." The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird's­eye view.

    It's really true what people say about English politeness: it's everywhere. When squeezing past someone in a narrow aisle, people say "sorry". When getting off a bus, English passengers say "thank you" rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes inevitable, and the bus driver is merely doing his job. I used to think the same way, without questioning it, until I started travelling to the British Isles and came to appreciate some more polite ways of interacting with people.

    People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be unusual to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposed to Germans.

    Another thing I observed during my stay was that English people rarely criticize others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men.

    I'm a real book lover. Every time my friends visit me, my nose is buried in a book. Wherever I go, I always have a book with me. Novels, history books, stories about people, journals and news­I read them all and I've learnt a lot, too. For example, many things in life happen for the best even if we don't like or understand them.

    Why is reading such an enjoyable pastime for me? I probably first learned about it from my parents. My mother read to me at night in my childhood and bought me picture books. The greatest gift she has given me is a love for reading. And it will be a life-long habit.

    No one ever asked me why I liked to read. They just saw me and asked, "Oh? Is that for school work?" And I just shook my head, "No. It's just for fun." While reading a good book, I can totally forget myself and fly to another world. It's like exploring through someone's eyes, which is just as exciting as watching a movie.

    Reading is also necessary in order to learn about writing, to improve my use of words and phrases and broaden my knowledge. What a pity to see our imagination disappear, for we don't exercise it often. Reading can even be good for one's health, I think. Everyone should read sad stories that make us cry and also books with humor that make us laugh out loud!

    It's difficult to know the exact answer to whether babies dream and what they dream about. However, sleep experts have shown that newborns dream the most in the first two weeks after birth. Babies spend most of their sleeping time in REM(rapid eye movement) stage. As dreaming takes place in a light state of sleep, newborns tend to wake up due to noises, movements and other factors. When dreaming, newborns make a few noises and their eyes move. They may move around the sides or up and down. They may laugh, scream, or cry during the REM sleep. Also, their facial muscles, hands, and legs move, due to which they may wake up. So wrapping a baby in swaddling(裹紧的) clothes can keep the baby's body from moving and help them sleep better. As babies grow, their body movement decreases when dreaming.

    Studies say that the brain activity associated with dreaming is essential for the babies' mental development. During the REM stage, the flow of blood to the brain increases. As a result, certain nerve proteins are produced, which are the building units of the brain. Babies get stimulation from what they see, hear, or feel. The brain processes the information acquired while awake, and stores what is essential to the individual. A study concludes that babies learned while they were dreaming.

    What's the time for babies to start dreaming? Researchers say that before birth, babies start experiencing REM sleep around week 25, and so they may start dreaming at the point. On the contrary, some psychologists believe that children start having dreams when they are about 5 years old. At that age, they start becoming aware of themselves and begin to understand the things around them, which is what dreams are actually made of.
