It seems the more time we have, the longer we put off living the life we see in our heads, because we feel like we've got some time to kill.

I know where you think I'm going with this, and I also know you've heard it all before: seize the day, make the most of it, live life to its fullest, and so on. But that's the problem. You've heard it all before. These ideas have their impact and have become a cliché. Luckily, that's not my thing.

The real answers wake something up inside you. They make you think. That's what I want to give you today, the story of Bobby Darin, which wakes you up to the truth.

If you haven't heard of the man, I know you've heard his songs. Among his many hits are Mack the Knife, Beyond the Sea, Dream Lover, and Splish Splash.

    If seven years, Darin had several top ten hit songs, was nominated(提名) for four Grammy Awards (winning two), nominated for four Golden Globes (winning one), and even nominated for an Oscar.

    So what was his secret?

All his life, Darin had a heart condition that developed from a childhood illness. The doctors at the time said he would be lucky to live to 16. In other words, his time was limited. And this was secret. He knew the truth. He knew that we all have such a hard time accepting: Life is short. You can't just say it; you can't just hear it. You have to know it, believe it, and feel it. Because Darin knew his time was limited, he packed as much life as he could into the time he had. But he had an unfair advantage. He knew, without a doubt, his time was limited.

    There was no fooling himself, no putting it off. It was now or never.

    Self-driving vehicles will rely on cameras, sensors and artificial intelligence（AI）to recognize and respond to road and traffic conditions, but sensing is the most effective for objects and movement in the neighborhood of the vehicle. Not everything important in a car's environment will be caught by the vehicle's camera. Another vehicle approaching at high speed on a collision （碰撞）track might not be visible until it's too late. This is why vehicle-to-vehicle communication is undergoing rapid development. Our research shows that cars will need to be able to chat and cooperate on the road, although the technical challenges are considerable.

    Applications for vehicle-to-vehicle communication range from vehicles driving together in a row, to safety messages about nearby emergency vehicles. Vehicles could alert each other to avoid collisions or share notices about passers-by and bicycles.

    From as far as several hundred metres away, vehicles could exchange messages with one another or receive information from roadside units（RSUs）about nearby incidents or dangerous road conditions through 4G network A high level of A1 seems required for such vehicles, not only to self-drive from A to B, but also to react intelligently to messages received. Vehicles will need to plan, reason, strategize and adapt in the light of information received in real time and to carry out cooperative behaviours. For example, a group of autonomous vehicles might avoid a route together because of potential risks, or a vehicle could decide to drop someone off earlier due to messages received, a foreseen crowding ahead.

    Further applications of vehicle-to-vehicle communication are still being researched, including how to perform cooperative behaviour.

    Robots writing newspapers

    Whether it's robots working as hotel receptionists or artificial intelligence creating poetry, it's becoming more and more common to read about technology doing the jobs of humans.

    And now, it seems that software is even capable of writing news stories –such as the very one you're reading.

    Recently the Press Association (PA), a UK news service, has created a computer program that's capable of creating articles that are almost impossible to tell apart from those written by human journalists.

    Called “robo-journalism”, such software “teaches” itself by analyzing thousands of news stories written by humans. The PA's software is already so advanced that many UK newspapers and websites publish articles created by it.

    According to the Reuters Institute of Journalism, many publishers are using robo-journalism to release interesting information quickly, from election results to official figures on social issues. For example, The Washington Post has its own robo-journalism software, Heliograf. Heliograf “wrote “over 850 articles in 2017, as well as hundreds of social media posts.

    So what does this mean for regular journalists?

    “We're naturally wary about any technology that could replace human beings,” Fredrick Kunkle, a Washington Post reporter, told Wired.

    “But this technology seems to have taken over only some of the work that nobody else wants to do.” “Indeed, it appears that robo-journalism software is designed to help humans, rather than take away their jobs.

    “In the future, Heliograf could do things like search the web to see what people are talking about, check The Washington Post to see if that story is being covered, and, if not, alert(提醒) editors or just write the piece itself.”Wired reporter Joe Keoha wrote.

    However, Joshua Benton at Harvard University's Nieman Journalism Lab believes that while robo-jounalism is undoubtedly going to become more present in newsrooms, nothing can replace traditional human creativity.

“Good journalism is not just a matter of inputs and outputs, it is a craft(技艺) that has developed over decades, “ he told BBC News. “The really difficult part of what professional journalists do—carefully weighing information and presenting balanced , contextualized(全景式的) stories —will be very hard for machines to master.

    It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I'm paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”

    It turned out that the woman, Natalie Smith, had read something on a friend's refrigerator: “Practice random(随意的，随机的) kindness and aimless acts of beauty.” The phrase impressed her so much that she copied it down.

    Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she'd taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn't know where it came from or what it really meant.

    Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.

    “Here's the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies (imagination) include painting the classrooms of poor schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”

    The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!

The Museum of Science and Industry

    The Manchester Museum of Science and Industry will give us a more wonderful interpretation of the museum. The 2.8 hectare museum was rebuilt on the site of a huge Victorian warehouse and the world's oldest passenger train station. The number and type of collections are ranked first, and in the power exhibition hall, steam engines used during the Industrial Revolution can still be seen. The display of the railway here is rich and vivid in content. Understanding the history of the Industrial Revolution, the Manchester Museum of Science and Industry is a good choice.

    Power is the central theme of the museum, whether it is a bicycle or a steam engine, not to mention an old car. The history of mankind, as this museum shows, has been constantly running. All human inventions can't be separated from this idea. Life is also about exercise. All the exhibits in the museum are alive. The workers oil and wipe every day. Finally, steam is imported into the machinery to make them run as usual as they did a hundred years ago. Time is also reversed.

    In the power exhibition hall, the steam engine that had been used during the Industrial Revolution was still roaring, and the influence was not reduced. If you want to understand the Industrial Revolution and the role of Manchester in it, you must come and visit it, and you will find answers from the many wonderful exhibitions here.

    The Manchester Museum of Science and Industry completely reproduced the British Industrial Revolution, and ensured that the machines of its scientific and technological inventions operated daily, so that visitors and school children could experience the Industrial Revolution. Therefore, the museum has become an outstanding model for preserving industrial heritage.

    Manchester was known as Cotton Capital, Northern Capital, Second City, and Warehouse City for the Industrial Revolution. The Manchester Museum of Science and Industry is located in the center of Manchester City. It records the cradle (摇篮) of the Industrial Revolution with historical details. Manchester City's history, textiles, energy, communications, aviation, transportation and other industries have risen and fallen with the development of science and technology.

Most of Bangladesh is at or below sea level. Rising seawater linked to climate change has severely affected the country. High water from storms in coastal areas also adds salt to soil. The land is becoming salty. Crops are less productive and many areas of cropland in the country are becoming unfit for farming. These are big problems for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

To find a way out，farmers in the country are learning to grow vegetables in so-called "vertical gardens". The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain (排水).

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

The farmers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12—$13 to build.
