Stephen Hawking, the brilliant British theoretical physicist who published wildly popular books exploring the mysteries of the universe, has died, according to a family spokesman. He was 76.

    Considered by many to be the world's greatest living scientist, Hawking was also a cosmologist, astronomer, mathematician and author of numerous books including the landmark“A Brief History of Time,” which has sold more than 10 million copies.

    With fellow physicist Roger Penrose, Hawking combined Einstein's theory of relativity with quantum theory(量子理论) to suggest that space and time would begin with the Big Bang and end in black holes. He also discovered that black holes were not completely black but emit(释放) radiation and would likely eventually evaporate(蒸发) and disappear. “It will be difficult enough to avoid disasters on planet Earth in the next 100 years, let alone next thousand, or million. The human race shouldn't have all its eggs in one basket or on one plant. Let's hope we can avoid dropping the basket until we have spread the load.”

    Hawking suffered from ALS (amyotrophic latcral sclerosis), a disease which is usually fatal within a few years. He was diagnosed in 1963, when he was 21, and doctors initially gave him only a few years to live. The disease left Hawking wheelchair-bound and paralyzed. He was able to move only a few fingers on one hand and was completely dependent on others or on technology for everything—bathing, dressing, eating, even speech. “I have been lucky that my condition has progressed more slowly than is often the case. But it shows that one need not lose hope.” Dramatically, he even guest-starred in the “Star Trek”, “The Simpsons” and the 2014movie “The theory of Everything”.

    Hawking leaves behind three children and three grandchildren. “We are deeply saddened that our beloved father passed away today,” Hawking's children, Lucy, Robert and Tim, said in a statement. “He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humor inspired people across the world. “We will miss him forever.”

    “The first and best of victories for a man is to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (冲动) and feelings, and from that moment he gives up his moral freedom.

    A single angry word has lost many friends. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whoever the gods would destroy they first make them mad.” “Keep cool,” says Webster, “anger is not argument.” “Be calm in arguing,” says George Herbert, “for fierceness (狂怒) makes error a fault.”

    To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “begins with foolishness and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.

    Self-control is man's last and greatest victory.

    If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking too.

    When the fork was stolen off Bart Michiels's mountain bike last summer, he wheeled it nearly three miles from his home in Chelsea to Frank's Bike Shop on the eastern end of Grand Street.

Mr. Michiels passed many other bike shops along the way, including one that offers free coffee. But for 20 years, he has remained devoted(忠实的) to Frank's. "Frank's the man," he said of Frank Arroyo, the owner. "I don't care where he is in the city — I'll go."

    Mr. Michiels doesn't have to worry about Mr. Arroyo's relocating(搬迁). The shop has stayed on the Lower East Side of Manhattan for 40 years.

    After Mr. Michiels left, Marvin Priess arrived. A professor of chemistry and math, Mr. Priess wheeled in the Ross 18-speed he had bought at Frank's in 1978 and still rides today, at age 68. Mr. Priess said that over the years, every single part of it that couldn't be repaired had been replaced, sometimes more than once, at Frank's. Customers don't come for the ambience(环境). It's crowded and dirty; buckets of parts and boxes of training wheels line the entryway.

    The store is filled with about 500 bikes and you will find Mr. Arroyo, 72, six days a week. He has been in the bike business since age 14. Born and raised on the Lower East Side, he has employed and taught many young people in the neighborhood. He is also willing to repair bikes in any condition, as well as his neighbors' walkers and wheelchairs.

    English Epps, a lawyer, needed a new seat; his had been stolen. "I've been coming here since I was in the third grade," he said, adding: "There's a new bike shop on Delancey Street, but everybody comes here."

    US Space Agency Returns to Mars with InSight Lander

    The American space agency's lander InSight is to arrive on Mars at the end of November, 2018. Unlike NASA's Curiosity rover, InSight will not move across the planet's surface. Instead it will become the first spacecraft (航天器) used only for exploring underground. It will study the geography of Mars, searching for signs of Martian (火星的) quakes.

    InSight is a project of U.S. and Europe. It is 6 meters long and 1.5 meters wide. It weighs 360kilograms. InSight's 1 .8 -meter robotic arm will put two experiments in place. Both are designed toexplore underground of Mars to learn about the inside.

    Bruce Banerdt is the lead scientist for InSight. He viewed the spacecraft as a robot that can take care of itself. "It's got its own brain. It's got an arm. It can listen and feel things. It pulls its own power out of the sun," he noted.

    Thomas Zurbuchen, one of the heads in NASA, said the results of the InSight project could "change the way we think about the inside of our earth." But, first, InSight will have to land on Mars undamaged. Since Mars exploration started in the 1960s, only about 40 percent of the explorations have succeeded.

    Tom Hoffman is InSight's project manager. He said earlier successes do not lessen the concerns for each new exploration. "That we ve done it before doesn't mean we're not nervous and excited about doing it again," he said.

    InSight will enter the Martian atmosphere (大气层) traveling at 19,800 kilometers an hour. It will slow for landing on a wide flat area on Mars. If all goes well, InSight could carry out its experiments in about 10 weeks. The InSight project is expected to continue for one Martian year, about two years on Earth.

    Vaping can be just as damaging to your health as smoking. But the minute you kick the habit, you'll feel a difference.

    Vaping is the use of electronic cigarettes-e-cigarettes. Vaping became mainstream in the United States in the late 2000s. When e-cigarettes first hit the market, people believed they were a safer choice to tobacco cigarettes. We now know, however, that vaping, like smoking cigarettes can be quite damaging to your health-and equally addictive.

    Kids and teenagers are especially attracted to vaping, thanks to attractive flavors. Vape use in high school students rose by 900 percent between 2011 and 2015.

    Quitting vaping can be difficult, just like trying to stop smoking. There are some immediate, though often temporary, negative effects. The positive ones soon outpace the negative, however.

    In as little as 20 minutes, your heart rate returns to normal, your blood pressure drops, and your circulation starts to normalize. Your breathing may improve, too.

    Daily e-cigarette doubles a person's risk for a heart attack. If you quit, however, the risk begins to fall very quickly. Also, vaping, like cigarette smoking, can blunt your senses, reducing your ability to smell and taste. After just 48 hours without vaping, you may begin to notice your ability to taste and smell food has improved. Nicotine affects more than your brain: new research suggests nicotine can raise your blood sugar, too.

    Smokers often have a troublesome cough or make a breathless sound when they breathe that many refer to as a smokers cough. Smoking even e-cigarettes can badly harm your lung health and make fighting off infections difficult. Quitting, however, will help your lungs recover. After one month, your lung capacity improves.

    There will come a day when the bad habit of vaping won't have any lasting influence on your body and your health.

AI-generated content has recently won big in the literary world. Japanese author Rie Kudan won one of Japan's most famous literary awards, the Akutagawa Prize, with the help of ChatGPT in The Tokyo Tower of Sympathy. 

The book is set in future Japan, where AI has become an important part of people's lives. The story centers around an architect who creates a comfortable prison but struggles with a society that she sees as being overly sympathetic to criminals. 

Kudan admitted at a news conference that "around 5 percent of the book's text was taken directly from generative AI," reported kyodo News. She added that there is a scene in the book where an AI chatbot answers the main character's questions and she used AI-generated text in the responses given by AI in the story. The word-for-word content generated by AI was applauded by committee members as "practically flawless", said CNN. 

This is not the first time that Al-related works have won prizes. In October 2023, The Land of Machine Memorieswas awarded second prize at China's fifth youth popular science and science fiction competition. The fiction was fully created by AI with the prompts (提示) given by Shen Yang, a professor at Tsinghua University. Surprisingly, just one judge among the six of the competition realized that what they were reading was the product of a machine. 

So will literature in the future be all about AI? Debates are still ongoing on the matter. Japanese literary critic Akira Okawada told Tyodo News that "it is difficult for AI to create work that addresses ethical themes in depth". However, Chinese writer Luo Ping holds the positive view. "Improvements in technology will not cause human laziness in creating, but rather will only make them involved in more heated competition. With the help of technology, the starting point of human thinking will only grow higher," Luo told Hongxing News. 

"I think this is only the beginning for AI in creating literature," Fu Changyi, a member of Jiangsu Popular Science Writers Association, told online news Guancha. "We will wait and see how the future goes," he added.
