    Christmas was near a season that we took seriously in our house. But a week or so before the 25th, my father would give each of his children $ 20. This was the 1970s, and $ 20 was quite a bit of money.

    But I saw it differently. My father trusted me to have the smart to spend money wisely. Even better, he gave me the means to get it. On a very basic level, my father was giving me a shopping spree (狂欢) every year.. But he was also giving me charge over my own fun, trusting my ability to manage money and making me feel like a grown-up. He didn't buy me Sherlock Holmes, but he gave me the means to walk into the bookstore and choose it for myself, so it felt like a gift from him.

    My mother had a gift for giving me what I needed, usually right at the moment I needed it most. This was when I was 25, I failed at being an adult on my very first try. I had quitted my previous job but had no new one. But when my mother paid me a visit, I put on a good show, telling her I had started my own company.

    My mother knew that I was trying hard and failing at that time. It wasn't until after she left that I noticed at the foot of my bed an envelope thick with cash. She knew how desperately I needed it. She knew that had she just shown up with groceries, or offered to pay my rent, she would have made me feel much worse. The cold, hard cash meant she was helping me. And, funnily enough, the distance with which she gave the gift felt like she was giving me space to fix my life and preserve my dignity. My mother and father both did the same thing. One was giving me the means to take my own decisions, and the other was giving me a second chance when those decisions had cost me dearly.

    For incoming freshmen at western Connecticut's suburban Brookfield High School, lifting a backpack weighed down with textbooks is about to give way to tapping out notes and touching electronic pages on an iPad. A few hours away, every student at Burlington High School near Boston will also start the year with new school-issued ipads, each loaded with electronic textbooks and other online resources in place of traditional texts. Apple officials say they know of more than 600 districts that have launched what are called " one-to-one " programs.

    At Burlington High in suburban Boston, Principal Patrick Larkin says the $500 ipads is better than textbooks in the long term, though he said the school will still use traditional texts in some courses if suitable electronic programs aren't yet available. Larkin said of textbooks, " but they're pretty much outdated the minute they're printed and certainly by the time they're delivered".

    But some experts warn that the districts need to ensure they can support the wireless infrastructure (设施 ), repairs and other costs that accompany a switch to such a tech-heavy approach. Mark Warschauer, an education and informatics(信息学)  professor said,  "I think people will like it.I really don't know anybody in high school that wouldn't want to get an iPad," he said. "We're always using technology at home, then when you're at school it's textbooks. So it's a good way to put all of that together." Districts are varied in their policies on how they police students' use.

    And the nation's textbook publishing industry, accounting for $ 5.5 billion in yearly sales to secondary schools, is taking notice of the trend with its own shift in a competitive race toward developing curriculum specifically for ipads.Jay Dickey, executive director of the Association of American Publishers'schools division, said all of the major textbook publishers are moving toward electronic offerings, but at least in the short term, traditional bound textbooks are here to stay. "I think one of the real key questions that will be answered over the next several years is what sort of things work best in print for students and what sort of things work best digitally."

    Yesterday night, over a dinner with my elder brother's family, a topic of happiness came up. My wife, Marla, a psychologist, was sharing Csikszentmihalyi's concept of “flow” with us. Marla explained that according to the research on flow, people are happiest when they are absorbed in a task that is just challenging enough for them to experience a sense of mastery(熟练).

    A few moments later my brother, Yuri, offered the following opinion: “The first and only, necessary and sufficient factor for happiness is to stop associating happiness with pleasure. The two — happiness and pleasure — have nothing to do with each other.” This morning, with my cup of coffee, I searched through a pile of books on my bedside table and—at the bottom—found a book by Bertrand Russell, I started reading but didn't finish. In it, I found the following thought:

    “The human animal, like others, is adapted to a certain amount of struggle for life, and when by means of great wealth homo sapiens can gratify all his whims (突发奇想) without effort, the mere absence of effort from his life removes an essential ingredient of happiness.”

    The conversation came full circle: people are happiest when they are in a state of flow (Csikszentmihalyi's language )…which is the effortful devotion in a moment…which has nothing to do with pleasure.

    Indeed, as Yuri insisted : happiness–as–pleasure is a myth; the association between happiness and pleasure is nothing but a semantic(语义的) habit; psychologically, the two—happiness and pleasure—are arguably different; and breaking up this association between pleasure and happiness might, in fact, be a powerfully first step in pursuit of happiness.

    As I look back on that exchange, I recall that there was an effort, a struggle to find a common understanding about this seemingly difficult idea—a struggle that made me happy.

    Moving flight times from night to day could reduce air travel's contributions to global warming, a new study suggests. Scheduling more (lay time flights may reduce the influence of contrails ——the visible lines of white steam that many planes leave behind them in the sky.

    The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.

    Nicola Stuber, first author of the study, suggests that contrails' overall impact on climate change is almost as big as that of aircraft^? s carbon dioxide emissions (排放)over a hundred-year period. Aircraft are believed to be responsible for 2-3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. However, they also trap energy in the atmosphere and increase the warming effect.

    Stuber and other scientists believe that the effect of the contrails is big. "On average, the green-house effect controls the effects of contrails, said Stuber, a meteorologist at England's University of Reading." The warming effect is far greater for contrails left by night flights," Stuber added. "The cooling effect only happens (luring the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of night-flight is so large."

    Most commercial airline traffic occurs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.
