Television has turned 88 years old onSeptember 7, 2015, and it has never looked better. In its youth, television wasa piece of furniture with a tiny, round screen showing unclear pictures oflow-budget programs. In spite of its shortcomings, it became popular. Between1950 and 1963, the number of American families with a television jumped from 9%to 92% of the population.

    As the audience got larger, thetechnology got better. Television sets became more reliable through the 1960s.The reception (接收效果) improved. The picture improved. The major networks started broadcastingprograms in color.

    Even greater improvements were comingaccording to Sanford Brown, who wrote an article for the Post in 1967. Surprisingly, just about every prediction he made in the article became areality. For example: All sets in the not-distant future will be colorinstruments. He also predicted that TV sets would become smaller, simpler, morereliable and less expensive and may forever put the TV repairman out of work.Smaller sets do not, of course, mean smaller screens. TV engineers expectscreens to get much bigger. However, today's 3-D TV is even farther away, if it's coming at all. There is some doubt whether the public would be eager topay for it, in view of people's cold reception given to 3-D movies.

    But the technology with the greatestpotential, according to Brown, was cable television (有线电视), whichwas still in its early stages then. As he predicted, the future of cabletelevision was highly interactive (互动的). It wasn't cable television that gaveAmericans their electronic connection to the world, however. It was theInternet. He even foresaw the future office: using picture phones, big-screentelevisions for conferences, and computers providing information at the touchof a button.

    Brown ever said, “The future oftelevision is no longer a question of what we can invent. It's a question ofwhat we want.”

    Sometimes people call each other “scared-cat”. But have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood stream. Although the cat doesn't realize this, its body is getting ready for action. If the danger continues, the animal will do one of two things .It will protect itself, or it will run away as fast as it can.

    Something like this also happens to people. When we are excited, angry or seared by other feelings, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run.

    Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger or hit somebody and regretted it later? Have you ever shouted at a teacher, told someone you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn't always clever to express your feelings freely.

    Does this mean that it's smarter always to hide our feelings? No! If you keep feelings of anger, sadness hidden away or bottled up inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. It can actually be bad for your health. It isn't good to keep pleasant feelings inside either; all feelings need to be expressed.

    Feelings that you keep all bottled up inside, don't just go away. It's as if you bought some bananas and put them in a cupboard. You might not be able to see them, but before you'd smell them. And if you opened the cupboard, chances are that you'd see little fruit flies flying all over them. They are bad.

    You can try to treat feelings as if they were bananas in the cupboard. You can hide them and you can pretend they don't exist, but they'll still be around. And at last you'll have to deal with them, just like those bananas.

    It may surprise bookworms, but apparently masterpieces such as Jane Eyre are lacking in something — sound effects. An electronic-book firm is adding background noises and music to the works of Charlotte Bronte, Sir Arthur Conan Doyle and William Shakespeare in the hope of attracting younger readers. In one example, a description of rain lashing against a window in a Sherlock Holmes story will be“enhanced”with matching noises.

    The first multimedia e-books — with sounds to accompany novels — will be available this Friday in the UK. The Booktrack releases are available to iPad users, with other tablet computer versions to follow. The concept is already in use in the U.S., where the classics come with added sound effects. Readers for example can hear the china cups chinking in Mr. Darcy's garden as they read Pride And Prejudice.

    A story by Booker Prize winner Salman Rushdie will be released later in the year with a specially crafted orchestral score. Rushdie's story In The South will be released with a soundtrack provided by the New Zealand Symphony Orchestra.

    The Power Of Six by Pittacus Lore, a novel for young adults, is one of the first to be tested with a soundtrack which builds in suspense in keeping with the plot. It works by timing the speed of each reader and the software measures the “turning” of a page and moves the music or sounds along accordingly. It has been created by Booktrack which synchronizes (使同步) music to each novel. It is funded by Peter Thiel, a co-founder of PayPal.

    Mr. Thiel said, “It's always exciting to witness the creation of a new form of media. The technology promises to captivate readers in a different way.”

    However, they have been greeted with horror by traditionalists, who say the technology takes away the pleasure of having one's imagination stimulated by a story. They also raise the prospect (预期) of having to ask an overly eager reader to turn their book down. David Nicholls, whose bestseller One Day was recently turned into a film starring Anne Hathaway, said, “This sounds like the opposite of reading. It would be a distraction.”

    Filled with much housework, meals and childcare at home, many people feel that being at work sounds more like having a picnic. Even for those who have a happy family life, they feel actually more stressed at home than at work.

    Recently, a study carried out by the researchers at a university in the USA found lower levels of hormone released in response to stress in a majority of subjects when they were at work compared to when they were at home. This was true for both men and women, and parents and people without children.

    Both men and women showed less stress at work. But women are more likely to report feeling happier there. Men were more likely to feel happier at home. Experts say there are other reasons why work is less stressful than home for many. “Paid work is more valued in society,” said Sarah Damaske, the lead researcher on the study, “Household work is boring and not particularly rewarding.”

    We get better at our job with time and the increased competence means less stress and more rewards. Yet none of us, no matter how long we've been doing it, ever truly feels like an expert at parenting or even at marriage.

    The support and friendship of co-workers also offer stress relief. At home, meanwhile, stress spreads and increases quickly. “That's the reason why most housewives wish they were the bread earners,” Dr. Damaske says.

    Much of the advice to families and couples includes the warning to “leave work stress at office” and even to change our mind-set from work to home, for example, a walk around the block. The recent findings, though, suggest our home life, not our attitude, might be due for some change.

The Rapid Rise and Fall of Robot Babysitters

    During the winter of 2017, an 18-year old college student named Canon Reeves spent much of his time trailing a knee-high robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a start-up called Starship Technologies in 2014, is basically a cooler on wheels; it uses radars, sensors, and nine cameras to make deliveries. Reeves's job was to monitor how it handled various grounds, field comments from the public, and press the off switch if necessary. He said, "People would also ask if it could deliver beer." It couldn't.

    Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, Indeed.com had almost three times the number of positions on the recruitment committee that ended in June 2016.

    Over the last year, a 34-year-old businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley's campus while it delivered Red bull and other drinks to students. To retrieve (检索) orders, the app encourages students to give the robot a wave; the robot's digital eyes will roll depending on its mood. Rodriguez, who heads business development for the start-up, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won't be out of work. Everyone holds double roles in the company. Greater robot self-governing just means employees will shift their focus to accounting, engineering, and design.

    Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. "A huge number of jobs will be produced as autonomous vehicles are released into the environment," Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a community college in Michigan, in autonomous-vehicle repair; Toyota has trained students in maintenance as well. "We might even see a return to low-level jobs where people come and fuel the car for you," Ramsey said. "Until we can wirelessly charge, someone needs to refuel them." The hardest-to-automate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.
