Telepathy (心灵感应) is the ability to communicate without the use of the five senses. It's an instinct (本能) which can be woken up in times of emergency or need. When we feel that something is happening or about to happen by instinct, we're using resources within the unconscious mind. When the resources of two persons' unconscious minds link together into the same frequency (频率), we call it telepathy.

    We can either send or receive telepathy. If you know who is calling before you answer the ringing phone，you are probably a good receiver. If you think of a person and he/she calls you，you are most likely to be better at sending.

    You can easily put your ability to the test. Thinking of somebody and wish him or her to contact you. Be patient. The other person may not be a good receiver，but they should contact you much earlier than would normally be expected. Or whenever the phone rings，try ‘feeling' who is contacting you. Don't guess, but try to feel it with your mind. However，if neither of these works for you，that doesn't mean that you have no ability of telepathy. As mentioned earlier, telepathy is most likely to turn up in case of emergency.

    Telepathy dreams often contain telepathic messages. Two people may both dream of the other and find that their dreams have a clear connection. These people are probably linking to each other's unconscious mind.

    Telepathy & relationship. The more people spend time together, the more likely they are to be able to link up to the other's mind, especially when separated. There are two reasons for this. One is that they understand the other's mind through time spent together; the other is that there is usually a strong desire to communicate. A mother will often sense that her child is in danger. This is due to the child's eagerly wanting his or her mother, knowing that this is the person who would always want to be there for them, and the mother's deep desire to protect her child from harm.

    Michael Faraday was the son of a blacksmith. There were four children in his family and, with his father often ill and unable to work, Michael Faraday had to earn his living from an early age. This meant little or no schooling. However, the family belonged to a religious group, and Faraday learnt to read and write at Sunday School.

    When he was only fourteen, Faraday found a job as a bookbinder（装订工）.He used to read the books he was given to bind and he became very interested in the scientific books, particularly the ones about electricity. His interest soon took a practical path and he began conducting his own experiments. These were very basic because Faraday had to make all of his equipment himself. However, he was very careful and kept a clear written record of all his findings.

    One day he was given an entrance ticket to the Royal Institute chemistry lecture, given by Humphry Davy. Determined to work for this great scientist, he sent Davy a job application and included his laboratory reports on the experiments he had carried out. In 1813 Davy offered Faraday a job as one of his laboratory assistants. Faraday learnt quickly and soon was recognized as a very able analytical chemist. Later he went to work at the Royal Institute.

    Michael Faraday was, perhaps, the greatest practical scientist of the 19th century. As a chemist, he discovered the benzene（苯）,which is now the focal point of chemical study. He also proved the relationship between electricity and chemical bonding（化学键合）.As a physicist, he invented the dynamo, which led to the later invention of the electric motor. He also discovered the effect of magnetism（磁）on light rays.

    No one can deny that buttons are an important clothing device. But, can they rise to the level of art? Organizers of an exhibit in New York City think so.

    Peter Souleo Wright organized “The Button Show” at Rush Arts Gallery in the Chelsea neighborhood of Manhattan. Eleven artists used the small, ordinary objects to create sculptures, portraits and wearable art. Some of the works are political, some are personal and others are just fun.

    Wright said each artist reimagines and repurposes the buttons to make art. “What I tried to do with this show,” he said, “was to look at artists who were promoting that level of craft.”

    He said he wanted the button art to be comparable to a painting “because of the amount of detail and precision in the work.”

    Artist Beau McCall produced “A Harlem Hangover”. It looks like a wine bottle that fell over on a table. A stream of connected red buttons hand over the side, like wine flowing down. Similar red button form a small pool on the floor.

    McCall layers buttons of different shapes and sizes to create the bottle. The stitching that holds them together is also part of the artistic design.

    For San Francisco-based artist Lisa Kokin, buttons are highly personal. After her father died in 2001, she created a portrait of him using only buttons. That memorial to her father led to other button portraits, including those of activists Rosa Parks and Cesar Chavez.

    Others use buttons for details. Artist Amalia Amaki of Tuscaloosa, Alabama, placed them on and around old photographs. Los Angeles artist Camilla Taylor attached buttons to three large sculptures that look like headless animals with long, narrow legs.

    “The Button Show” ends at March 12. The Rush Philanthropic Arts Foundation paid for the exhibition. The foundation was created in 1995 by the Simmons brothers: artist Danny, hip-hop producer Russell and rapper Rev. Run. The foundation seeks to bring the arts to urban youth and to provide support for new artists.

    Janet Guthrie and Danica Patrick, first female Indy competitor and winner

    No complaints about woman drivers. Janet Guthrie, an space engineer who was training to be an astronaut, turned to car racing when she was cut from the space program for not having completed her doctors degree. In 1977, Guthrie became the first female Indy 500 competitor. She didn't take the lead, but Danica Patrick did. In 2005 and in 2008, Patrick became the first woman ever to win an Indy Car Series.

    Raymonde de Laroche, first female licensed pilot

    A former actress who'd been born Elise Raymonde Deroche in Paris in 1882, Raymonde de Laroche was inspired to take up flying after seeing the Wright Brothers flight demonstrations in 1907 in France. Though she wasn't the first female pilot, de Laroche was the first woman to earn a pilot's license in 1910.

    Gertrude Ederle, first woman to swim across the English Channel

    On August 6. 1926. Gertrude Caroline Ederle became the first woman to swim across the English Channel. Ederle, who lived to be 98 and died in 2003, was also an Olympic swim champion and five-time world record-holder in five swimming events

    Kathrine Switzer, Nina Kuscik and Joan Benoit, first major female marathoners.

    In 1967, 20-year-old Kathrine Switzer became the first woman to run in the Boston Marathon, even though race officials had tried to stop her. Nina Kuscik became the first woman to officially win the Boston Marathon, 1972. In 1984, American Joan Benoit became the first winner of the Women's Olympic Marathon, finishing 400 meters ahead of Norway's Grete Waitz.

5 books I loved in 2018

By Bill Gates

    A great read is the perfect gift and I think everyone could use a few more books in their lives. My book list covers various topics, including an autobiography on learning throughout a life, a deep search on autonomous weapons (武器), a thriller about the fall of a once­promising company and a guide about meditation (冥想)­there's something for everyone.

    The Head space Guide to Meditation and Mindfulness, by Andy Puddicombe. The book starts with Puddicombe's personal journey from a university student to a Buddhist monk and then becomes an entertaining explainer on how to meditate. If you're thinking about trying mindfulness, this is the perfect introduction.

    Army of None, by Paul Scharre. It's an extremely complicated topic, but Scharre offers clear explanations and presents both the advantages and disadvantages of machine­driven warfare. His fluency with the subject should come as no surprise: he's an ex­soldier who helped draw up the U.S. government's policy on autonomous weapons.

    Bad Blood, by John Carreyrou. Carreyrou gives you the definitive insider's look at the rise and fall of a company. I found myself unable to put it down once I started. This book has everything: magazine cover stories, ruined family relationships, and the failure of a company once valued at nearly $10 billion.

    21 Lessons for the 21st Century, by Yuval Noah Harari. I'm a big fan of everything Harari has written, and his latest is no exception. If 2018 has left you stressed out by the state of the world, 21 Lessons offers a helpful framework for processing the news and thinking about the challenges we face.

    Educated, by Tara West over. Tara never went to school or visited a doctor until she left home at 17. I loved this life story of a young woman whose thirst for learning was so strong that she ended up getting a P.h.D. from Cambridge University.

    A butterfly's wings can have many jobs besides keeping the insect in the air. They may be called on to attract mates, to warn potential enemies to stay away, to do other animals or even to provide disguise(伪装).

    All of these roles, though, depend on their colouration-which is unchanging. This plays into the idea that butterfly wings are dead tissue, like a bird's feathers or a mammal's hair. In fact, that is not true. For example, in some species males' wings harbour special cells that release chemicals which attract females.

    Nanfang Yu, a physicist at Columbia University, in New York, has been looking into the matter. One of his interests is the optical (光学的) properties of biological materials. That has led him to study butterfly wings in more detail. And, in cooperation with Naomi Pierce, a butterfly specialist at Harvard University, he has now shown, in a paper published this week in Nature Communications, that butterfly wings are, indeed, very much alive.

    Initially, Dr Yu and Dr Pierce wanted to know how the insects keep their body temperatures up without their wings overheating. Unlike birds and mammals, butterflies do not produce enough internal heat to metabolize(新陈代谢). Instead, they rely on outside heat sources-usually the sun-to bring their bodies up to speed. But their wings, being thin protein membranes (膜), have a limited thermal capacity. Those wings can therefore overheat quickly if the insects are exposed to the sunlight too long, or, oppositely, can cool down too rapidly if they are flying through cold air.

In their experiments, the two researchers used a laser (激光) to heat up spots on the wings of dozens of butterfly species. When the temperature of the area under the laser reached 40℃ or so, the insects responded within seconds by doing things that stopped their wings heating up further. These actions included a butterfly turning around to minimize its exposure to the laser, beating its wings or simply walking away.
