As a boy, Charles Robert Darwin(达尔文) collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him.

    His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin's interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin's great life.

    As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.

    Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin's great book “On the Origin of Species by Means of Natural Selection”(《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.

    Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was still working on 17, April, 1882. He was dead two days later.

    You may be familiar with those quotes, but seldom can you associate these quotes with those outstanding women behind them, not to mention the great work they did.

    “Despite everything, I believe that people are really good at heart.”

—Anne Frank (1929 — 1945)

    Hiding from the German forces, Anne Frank, a young Jewish girl, was gifted a diary by her father when she was 13. However, her diary was published after her death in Bergen-Belsen concentration camp at the age of 15. The diary served as a unique eye-witness account of life during Holocaust (mass murder of about six million Jews during World War II) and it became one of the world's most read books.

    “Not all of us can do great things• But we can do small things with great love.”

—Mother Teresa (1910 — 1997)

    Mother Teresa, the Nobel Peace Prize winner (1979), aimed at looking after those children who had nobody to look after them through her own order “the Missionaries of Charity”. She worked tirelessly towards her goal until her ill-health forced her to step down in March 1997, after which she took her last breath in September 1997.

    “If you set out to be liked, you would be prepared to compromise on anything at any time, and you would achieve nothing.”

—Margaret Thatcher (1925 — 2013)

    Margaret Thatcher was loved and hated equally for some of her policies but she never compromise (妥协). She was known as “the Iron Lady” for her leadership style. From being a grocer's daughter to graduating from Oxford University to becoming a banister, she went on to become Britain's first and to date, only female Prime Minister elected in 1979 and the country's fifth longest serving leader.

    “I knew someone had to take the first step and I made up my mind not to move.”

—Rosa Parks (1913 — 2005)

    Also known as “the first lady of civil rights”, Rosa Parks was a pioneer of civil rights in a racially segregated Alabama in 1950s. In 1955, she refused to give away her seat to a white passenger in a bus, disobeying the bus driver's orders. This act of hers sparked the Montgomery Bus Boycott that crippled the state capital's public transport system.

    Mark Twain, the famous American writer and a great master of humor, liked to play jokes on others. But once a joke was played on him. One day Mark Twain was invited to give a talk in a small town. At lunch he met a young man,one of his friends.

    The young man said that he had an uncle with him. He told Mark Twain that his uncle never laughed or smiled, and that nobody and nothing was able to make his uncle smile or laugh.

    “You bring your uncle to my talk this evening,” said Mark Twain. “I'm sure I can make him laugh.”

    That evening the young man and his uncle sat in the front. Mark Twain began to speak. He told several funny stories and made everyone in the room laugh. But the man never even smiled. Mark Twain told more funny stories, but the old man still kept quiet. Mark Twain continued to tell his funny stories. Finally he stopped. He was tired and quite disappointed.

    Some days later, Mark Twain told another friend what had happened. “Oh,” said his friend,“I know that man. He's been deaf for years.”

The young boy saw me, or rather, he saw the car and quickly ran up to me, eager to sell his bunches of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known the bitterness of life. "Bananas 300 naira. Peanuts 200 naira." He said in a low voice. I bargained him down to 200 for the fruit and nuts. When he agreed, I handed him a 500 naira bill. He didn't have change. So I told him not to worry. He said thanks and smiled a row of perfect teeth.

    When, two weeks later, I saw the boy again, I was more aware of my position in a society where it's not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents had raised me to be aware of the advantage we had been afforded and the responsibility it brought to us.

I pulled over and rolled down my window. He had a bunch of bananas and a bag of peanuts ready. I waved them away. "What's up?" asked him. "I…I don't have money to buy books for school." I reached into my pocket and handed him two fresh 500 naira bills. "Will this help?" I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year. "Thank you, sir." he said. "Thank you very much!"

    When driving home, I wondered if my little friend actually used the money for schoolbooks. What if he's a cheat? And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? I didn't know his name or the least bit about him, nor did I think to ask.

    Over the next six months, I was busy working in a news agency in northern Nigeria. Sometime after I returned, I went out for a drive. When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face.

"Oh, gosh! Long time."

"Are you in school now?" I asked.

    He nodded.

"That's good," I said. A silence fell as we looked at each other, and then I realized what he wanted. "Here," I held out a 500 naira bill. "Take this." He shook his head and stepped back as if hurt. "What's wrong?" I asked. "It's a gift."

He shook his head again and brought his hand from behind his back. His face shone with sweat. He dropped a bunch of bananas and a bag of peanuts in the front seat before he said, "I've been waiting to give these to you."

In 1991, Terry Gelber rented a stage at the Castillo Cultural Centre to perform his poetry. When asked by the booking agent what kind of poetry he wrote, his response was "Taxi Poetry".

While driving his taxi and reciting poetry, he noticed his taxi driver's licenses are also called "hack licenses". Then he thought for a moment and said, "Hack Poetry!" Thus "Hack Poetry" was born.

At the first reading of Hack Poetry, a fellow taxi driver and poet Tom Ostrowski joined Terry. The two cabbie poets read to an audience of six people plus one reporter from New York Magazine. Asked by Charles W. Bell of the New York Daily News what he called the growing group of taxi poets that appeared at readings, Gelber replied, "Did you see the movie Dead Poets Society?"

In 1992, a poetry contest was added and a television game show was produced for Manhattan TV. In the following years, Terry appeared as the Hack Poet at lots of events reading his Hack Poetry and writing poems for special days such as when an old taxi was put in the Museum of New York. After a successful business in 1999, the Hack Poet bought an old farm in the Catskill Mountains where he has been able to be close to nature and animals. Poets will be invited to share the loneliness of the hills in a place that thankfully has not quite moved into the 21st century. 

Robots have long been drawing inspiration from animals, with the creation of robot dogs or snake-shaped robots. And yet, the field of robotics is far less enthusiastic about the other kind of living things—plants. Barbara Mazzolai, an Italian roboticist owes this to a misconception about plant behavior: that they cannot move or think. "It's not true at all," she says. To challenge this view, Dr Mazzolai and her team recently launched a machine called "FiloBot", a robot based on a climbing species.

To survive, a climbing plant must switch between several different behaviors. In forest environments, it must first grow out of the soil and travel along the ground in search of a support to hold onto, such as a nearby tree. Once a support is located, though, the plant fixes itself around the object and then growing towards the light. To choose the best angle to grow upwards, a climbing plant uses its shoots(芽) to receive information about light and gravity.

FiloBot has sensors on its main shoot. It can 3D-print its body with plastic and grow at a controllable rate. These functions researchers found, enabled FiloBot to cross gaps, and find things to attach to. The lack of heavy on-board computing device means that it is light and requires minimal care, while its slow pace means that it doesn't disturb things around it, making it possible to move through a complex, unseen environment, or monitoring disaster sites.

For now, FiloBot is still being tested. Its tendrils(卷须) have not left the laboratory. Still, it has already been employed in deconstructing plant behaviour. For example, it was long assumed that climbing plants find their supports by growing towards shade, though the exact mechanism was unclear. FiloBot could imitate this behaviour by detecting far-red light, which is typical of shaded areas, providing clues to how plants do it.

Dr Mazzolai hopes that such projects will inspire other roboticists to take their cues from plants and develop completely new technologies.
