A Brief History of Timekeeping with Chad Orzel
From Stonehenge to atomic clocks, here is the 5, 000-year history of how science is used to mark time. Chad Orzel, the internationally best-selling author of How to Teach Quantum Physics to Your Dog, offers us a witty joumey through scientific theory and quirky(反常的) historical detail.
Physics at the end of the universe with Katie Mack
The Big Bang theory tells the story of the beginning of the universe for the last 13. 8 billion years. But how does the story end? Join astronomer Katie Mack as she shares what modern astrophysics tells us about the final fate of the universe.
Edward O. Wilson who died on Dec. 26, 2021 at the age of 92, was an extraordinary scholar in every sense of the word. By the time I met him in 1982, he'd made great contributions to science. For example, he discovered the chemical means by which ants communicate. He worked out the importance of the habitat size and position in protecting animals.
In 1982 I cautiously sat down next to the great man during a break at a small conference on social insects. He turned, extended his hand and said, "Hi, I'm Ed Wilson. I don't believe we've met. "Then we talked until it was time to get back to the meeting. Three hours later I approached him again. He turned, extended his hand and said, "Hi, I'm Ed Wilson. I don't believe we've met. "
Wilson forgot me but remained friendly. I was fresh out of graduate school, while Wilson was already very famous. Yet he didn't hesitate to extend his hand to me, not once but twice.
My work studying native plants and insects was inspired by Wilson's descriptions of biodiversity. His 1992book, The Diversity of Life, became the basis for an eventual tum in my career path. Throughout his career, Wilson communicated the urgent need to preserve the natural world. As I see it, the only way to realize Wilson's lifelong wish is to bury the idea that humans are here and nature is someplace else. Providing a practical plan for protecting the earth has been my goal for the last 20 years, and I'm honored that it mixes with Wilson's thought.
There's nothing wrong with a tomato that isn't perfectly rounded or a peach with an extra dimple (浅凹) or two; they still carry the same benefits and flavors as the versions we're used to seeing in grocery stores. Farmers conventionally throw away these imperfect items, as many grocery chains won't buy them for fear that they are unsellable. However, a growing group of grocery chains are fighting to make these deserted fruits and vegetables part of consumers' buying habits.
One such business is Imperfect Produce, a start-up that delivers fresh ugly produce to consumers. Through this service, you can get up to 20 pounds of fruit and veggies for around $20 a week. This is about a 30 percent discount compared to what's currently sold in stores. Recently, the company had a major breakthrough when Whole Foods accepted their partnership and agreed to sell the misshapen (畸形的) produce.
While this movement might be a new trend here in the US, it's already gained serious momentum (势头) in Europe. In 2014, the E. U. announced the Year Against Food Waste, with French grocery chain Intermarche launching a very successful campaign called Inglorious Fruits and Vegetables and England's Waitrose selling "weather blemished" apples. In Portugal, a similar company to Imperfect Produce called Fruta Feia has also taken off.
Buying these unfortunate-looking foods should be appealing to consumers not only because of the affordability, but also because of the support it gives to farmers and the direct impact it has on decreasing food waste and the environmental pollution. It is believed that when the discarded fruits and vegetables decompose they release methane, a greenhouse gas that, when released into the gtmosphere, is about 86 times as powerful as carbon dioxide over a 20-year period. Waste is, in fact, the ugliest thing of all.
You don't need to be an expert to recognize luna moths(蚕蛾). They have hairy white bodies, red legs and huge green wings that stretch up to 4.5 inches across. And at the end of their wings are a pair of long tails that have attracted scientists for centuries.
Some of them theorized that it was possible that female moths judged the health and quality of a male by the size of his tails. But it turned out that female moths, were not choosy at all. They just mate with the first males they could find. Others believed that the tails could increase luna moths'size to make them harder for the bats—the main enemy of luna moths—to handle. But the theory proved wrong in 1903 when a scientist named Archibald Weeks put bats against a bigger species of moths that lacked tails. He found that the bats killed 66% of their targets. Luna moths, despite being smaller, were harder to catch. "Clearly, their tails provided an anti-bat atwantage, " Weeks observed. "I think they were used to direct bats away from the moths'body. "
He was roughly right. More than a century later, Jesse Barber from Boise State University put luna moths against bats in a dark room and filmed the hunting. Under normal circumstances, the bats only managed to catch 35% of the luna moths. But if Barber cut off their tails beforehand, the bats caught 81% of them. That was not because the moths became worse liers—in fact, cutting the troublesome tails seemed to have improved their flying abilities.
Barber explained that bats were not visual hunters. They found their food with a special sound. To be protected from bats, luna moths needed something that made confusing sounds. That was what the luna moths'tails did:As they flew, they waved behind them and produced sounds that were similar to their wing beats. To bats, they either sounded like a huge part of their target, or like an entirely different target. As a result, they aimed about half their attacks at the tails.
Maybe you are fearful of missing your holidays due to long waits for new passports. .
Check your passport to see when it was issued
"After travel took a pause for many holidaymakers during the pandemic, plenty of passports need to be renewed. To beat any disappointments for your summer vacations, you'll want to make sure that it has been no more than- en years since your passport was issued, " Naveen says, ", including popular travel spots such as Egypt, Thailand, and Dubai. "
"I'd recommend thoroughly checking your application before you send it off. Many delays are made through typical errors—such as incorrect photos or typos—which can worsen your chances of receiving a passport in time for a summer trip. "he continues.
Go for digital rather than paper
Naveen advises, "There are many variables (变数) that go into how long it will take to get your passport renewed—from a first-time passport to a child's renewal. When it comes to the method of how you apply, digital applications generally take a short amount of time as parts of the application are less likely to get lost, plus the online process will be more efficient. . "
Make an appointment in person or over the phone
"With the current demand for travel in recent months, even the fast-track services for passport renewal are becoming overwhelmed, so there is no quick fix(捷径) to receiving your passport on time, " he says. ". Altematively, look to book an appointment to one of the various passport centers across the country—that way you can speed up the process in person and have someone on hand should there be any errors. "
A. Ensure your details are correct
B. Admit your information of passports is right
C. Many people don't like the stressful life and want to travel
D. Keep this in mind if you don't want to end up being stuck in the waiting line
E. Naveen, founder of Next Vacay, has issued four tips to speed up the passport process
F. You also need the minimum of three or six months to guin entry into many destinations
C. However, if you are traveling for an emergency, you may be able to accelerate the process
Twelve years ago I decided to change my job from an English as a Second Language teacher to simply working at a department store childcare room, basically for better hours and benefits. My1were preschoolers. To my 2, many of these 2-4- year- old children3no English at all because shoppers at the store were families of employees at an international company with headquarters nearby. How4I found myself teaching English to preschoolers! Two experiences were unforgettably5for me — they came from a couple of little girls.
One child was about 3 years old when she6in the playroom. She was7, having recently come from Mexico and8only Spanish. However, I knew some Spanish, so we9time playing together while she10to English- speaking children around her. Eventually she11a local preschool and became12in English. One day she came to the playroom and13said to me," Teacher, remember when I called you ' maestra '?" Her bright eyes were filled with14!
The other child was also 3 years old when she came to the15that was filled with blocks, crayons and paper, tea sets, etc. She had no16in the town because her family had just moved from another17. She went to preschool later on, also, and showed her great18in speaking English! Then one day … after a long time away … she came into the playroom and said to me," Let's play blocks!" All our play was19with pleasure and learning and we played together cheerfully. From these children I learned to let extreme discomfort and the massive need for20become a springboard for joy and growth.
The TV series, A Lifelong Journey, (earn) widespread applause, becoming the most- watched TV series on State broadcaster China Media Group in the past five years.
A Lifelong Journey, (consist) of 58 episodes, is adapted from famous writer Liang Xiaosheng's novel of the same name which won the 10th Mao Dun Literature Prize, one of the country's top honors for local writers. Starting in late 1960s, the story follows the ups and downs of three children in a working- class family in northeastern China, striking a chord(和弦) with viewers for its details (vivid) bringing them back to old times. First (publishing) in December 2017, the novel shows a wide range of Chinese people from different (walk) of life, from constructors to start- up founders, to examine the huge influence brought by the changes of Chinese society.
Tie Ning, chairwoman of the China Writers' Association, said the great (popular) of the TV series, A Lifelong Journey, illustrates the " close bond " literature and television. " While taking a look at history, we could see the mutual(相互的) influence of literature, film and television to boost and inspire each other, has connected writers and filmmakers closely." she added. With popular TV series or movies, the stories that have inspired such screen works will see their influence grow even (far).

The weather has been like late summer this week, even though it is Noyember. I have caught chance and walked every morning. After that, I tend to reward me with a cup of coffee from the cafe wherever if used to meet my old friends. During this difficulty time, everyone seems to being running short of money. Yesterday, I take a bag of coins with me and paid with exact changes. I exchanged the remainder of my coins with paper money. The clerk was very much happy to offer me paper money and said that they could always use coins, no matter how small the amount was. Heard what she said, I felt really grateful and delighted.
