Read the following quote from "The Young American", by Ralph Waldo Emerson (1844):

"We must have kings, we must have nobles; nature is always providing such in every society: only let us have the real instead of the titular. In every society some are born to rule, and some to advise. The chief is the chief all the world over, only not his cap and plume. It is only this dislike of the pretender which makes men sometimes unjust to the true and finished man".

'Everything Everywhere All at Once' dominates at SAG Awards


(1º§) The unlikely awards season juggernaut Everything Everywhere All at Once marched on at the Screen Actors Guild Awards on Sunday, and even gathered steam with wins not just for best ensemble, Michelle Yeoh and Ke Huy Quan but also for Jamie Lee Curtis. (...)


(2º§) Though some have seen best actress as a toss up between Yeoh and BAFTA winner Cate Blanchett (Tár), Yeoh again took home the award for best female lead performance. "This is not just for me," said Yeoh, the first Asian actress to win the SAG Award for female lead. "It's for every little girl that looks like me." Quan, the former child star, also won for best supporting male actor. The Everything Everywhere All at Once co-star had left acting for years after auditions dried up. He's also the first Asian to win best male supporting actor at the SAG Awards.

Compensatory Strategies


     A common set of communication devices involves compensation for missing knowledge. These are called “compensatory strategies”. We will elaborate here on three of them.

   Typical of beginning-level learners, for example, is the memorization of certain phrases or sentences without internalized knowledge of their components. These memorized chunks of language, known as prefabricated patterns, include “on the way to”, “Nice to meet you”, “I don’t speak English.” Prefabricated patterns are sometimes the source of some fun. In my first days of Kikongo learning in Africa, I tried to say, in Kikongo, “I don’t know Kikongo” to those who attempted to converse with me; I later discovered that, instead of saying “Kizeyi Kikongo ko”, I had said “Kizoiele Kikongo ko” (I don’t like Kikongo).

    Code-switching is the use of a first or third language within a stream of speech in the second language. Learners in the early stages of acquisition might code-switch—use their native language to fill in missing knowledge—whether the hearer knows that native language or not. Sometimes the learner slips in just a word or two, in the hope that the hearer will get the gist of what is being communicated.

    Yet another common compensatory strategy is a direct appeal for help, often termed appeal to authority. Learners may, if stuck for a particular word or phrase, directly ask a proficient speaker or the teacher for the form (“How do you say            ?”). Or they might venture a possible guess and then ask for verification from the proficient speaker. They might also appeal to a bilingual dictionary for help. The latter case can also produce some rather amusing situations. Once a student of English as a second language, when asked to introduce himself to the class and the teacher, said, “Allow me to introduce myself and tell you some of the ...” At this point he quickly got out his pocket dictionary and, finding the word he wanted, continued, “some of the headlights of my past.”

(§ 2) Experienced flyer, Vanessa Grant recommends parents don't let their kids take a bag with them after sharing her recent experience of travelling with her kids - aged 8 and 11.


(§ 3) "Smart packing is what really saved us," she said.


(§ 4) Vanessa did two long-haul flights with her family from Canada to Indonesia which went smoothly because the kids didn't have bags, she claims.


(§ 5) It is important to "instil a sense of responsibility" in kids however, it is not worth the stress of tracking down a lost backpack __ a busy international airport, according to the travel expert.


(§ 6) Vanessa explained: "The stakes are just too high and even replacing a charging cord can be pricey at a duty-free shop, let alone a whole backpack's worth of stuff."


(§ 7) It is also important to bring the right type of carry-on when travelling with your family, to make your life a lot easier.


(§ 8) A small rolling suitcase is perfect for long-haul flights and "is like the clown car of carry-ons".


(§ 9) Vanessa added: "It fits a change of clothes for three of us, plus toiletries and some snacks."


(§ 10) Instead of storing your carry-on in the overhead bins you should put it __ the seat of your shortest child so they'll be able to rest their feet on it, Vanessa recommends.


(§ 11) This clever hack will stop your child from complaining as it is "uncomfortable to have your legs hanging for hours".

Climate crisis is making days longer, study finds

    Melting of ice is slowing planet’s rotation and could disrupt internet traffic, financial transactions and GPS. The climate crisis is causing the length of each day to get longer, analysis shows, as the mass melting of polar ice reshapes the planet.
    The phenomenon is a striking demonstration of how humanity’s actions are transforming the Earth, scientists said, rivalling natural processes that have existed for billions of years. The change in the length of the day is on the scale of milliseconds but this is enough to potentially disrupt internet traffic, financial transactions and GPS navigation, all of which rely on precise timekeeping.
    The length of the Earth’s day has been steadily increasing over geological time due to the gravitational drag of the moon on the planet’s oceans and land. However, the melting of the Greenland and Antarctic ice sheets due to human-caused global heating has been redistributing water stored at high latitudes into the world’s oceans, leading to more water in the seas nearer the equator. This makes the Earth more oblate – or fatter – slowing the rotation of the planet and lengthening the day still further.
   The planetary impact of humanity was also demonstrated recently by research that showed the redistribution of water had caused the Earth’s axis of rotation – the north and south poles – to move. Other work has revealed that humanity’s carbon emissions are shrinking the stratosphere.
    “We can see our impact as humans on the whole Earth system, not just locally, like the rise in temperature, but really fundamentally, altering how it moves in space and rotates,” said Prof Benedikt Soja of ETH Zurich in Switzerland. “Due to our carbon emissions, we have done this in just 100 or 200 years. Whereas the governing processes previously had been going on for billions of years, and that is striking.”

What Happens to Your Body When You Drink Milk Every Day


     Milk (and dairy in general) gets the blame for a lot of unwanted health outcomes. We're sure you've heard that dairy causes acne, increases inflammation and can even be the reason you're not losing weight. Spoiler: For those who aren't lactose-intolerant or allergic to dairy, research doesn't back up those claims. In fact, there are actually some impressive benefits that come with drinking a nutritious glass of milk.


Your Bone Health Might Improve


Not only is milk a great vegetarian protein source, but it's also packed with calcium and vitamin D—two nutrients that are vital for bone health. Calcium is a mineral needed to build and maintain strong bones, and vitamin D helps our body absorb calcium from the foods we eat. Since milk is a great source of both of these nutrients, it's one of the best things to keep in your diet for bone health throughout life. 


You Might Reach Your Weight Loss Goals


There are lots of misconceptions about how drinking milk can affect weight, but research shows regular consumption probably won't hurt your cause if you're trying to lose weight or maintain a healthy weight. This is largely due to the satisfying combination of carbohydrates, protein and fat found in milk. Protein and fat can help make milk super filling, which can help with weight loss. Carbs give you energy and help your body function at its best. When you're more satisfied from the foods you eat, it's easier to honor your hunger and fullness levels and stick to a healthy, balanced eating pattern.


A meta-analysis of randomized controlled trials (the gold standard of research) published in the journal Nutrients found that including dairy in a calorie-restricted diet resulted in greater weight loss and fat loss, while reducing loss of lean muscle. This doesn't mean milk is a miracle weight-loss food, though. Another review of studies found that consuming milk or other dairy products didn't result in significant weight loss, but didn't lead to weight gain either. If your goal is to lose weight or maintain a healthy weight, drinking a glass of milk each day might help, if it's a food you enjoy. You Might Lower Your Risk of Cognitive Decline


The impressive nutrition profile of milk could be a reason why it can help you stay more mentally sharp as you age. A 2021 review of studies published in Nutrition & Metabolism found that milk intake was connected with a decreased risk of Alzheimer's disease. Another study published in 2020 in the journal Nutrients found that skimmed dairy, fermented dairy and buttermilk were associated with better executive functioning. So adding some milk to your morning oats or as a side to a snack may help boost your brain health.


Researchers hypothesize that one reason milk might support healthy aging is the nutrition that it provides. Milk is a good source of calcium, protein and vitamin B12, all of which are critical nutrients for older adults.


The Bottom Line


If you aren't lactose-intolerant or allergic to dairy, it's totally OK to enjoy a regular glass of milk each day. From improving bone health to helping mitigate cognitive decline, drinking milk and incorporating other dairy items into your diet can come with some health benefits. As with any food, remember that moderation is key (an 8-ounce serving of milk probably wouldn't completely fill many of the glasses in your cupboard). Since there are dairy farmers all across the U.S., try choosing milk that is produced locally. Making a connection with a local farmer can help you get a better-quality product that takes less of a toll on the environment, too.


FONTE: Adapted from: https://www.eatingwell.com/article/7961444/what-happensto-your-body-if-you-drink-milk-every-day/#:~:text=Not%20only%20is% 20milk%20a,from%20the%20foods%20we%20eat.

Teaching methods keep changing with the times,................... the blackboard of the old days ........... electronic teaching today. Mr. Kam, physics instructor the Chinese University of Hong Kong, is one of those who has changed ......... the times.


Mr. Kam employs a two-pronged approach. First, he uses multimedia teaching materials during lectures. Second, he arranges internships for undergraduates. These can take the form of learning assistantships at the university or teaching assistantships at secondary schools, and also there’s always the odd science project at the Space Museum.

The initiatives have earned him the Faculty Exemplary Teaching Award 2020. A CUHK alumnus, he is grateful for the chance to teach at the university after earning his doctoral degree there. His teaching position actually represents the fulfillment of a dream, for the status of professors during his days as a university student was extremely high and he could meet them only during lectures.

After being a teacher for 10 years, Mr. Kam has found no apparent regression in the learning abilities of students, but he believes teachers should not just force knowledge on students - they have to pay careful attention to their needs too. 

The multimedia materials that Mr. Kam uses to illustrate his area of interest includes animation and video clips. He encourages students to read popular astronomy magazines and share any note-worthy content they find. Mr. Kam also gets his undergraduates to help prepare students sitting for physics papers in public exams or to help out on research projects undertaken by meteorological officers at the observatory.

He also arranges for his undergraduates to teach students from other faculties during physics liberal studies classes through talks and star-gazing expeditions. Such responsibilities serve two greater purposes.

First, undergraduates become even more motivated to learn when they find out they have to guide other students. Second, physics students are, unlike arts students, not at their best when called upon to express themselves. Acting as assistants allows them to practice their skills and build up their self- confidence.

I asked Mr. Kam what he found most satisfying in teaching.

And the answer is obvious. It is the deep friendship he forms with students. Mr. Kam says many former students still come back to see him occasionally despite being busy parents. He draws considerable satisfaction from seeing his students grow into mature adults.

For Mr. Kam, the best teachers will never find extracurricular activity a burden because the good work that is done today plants the seed for future generations. 
Considering the text, analyze the sentences below and the underlined words.

“Second, he arranges internships for undergraduates. These can take the form of learning assistantships at the university or teaching assistantships at secondary schools, and also there’s always the odd science project at the Space Museum.”

"While the origins of Maya culture remain murky, it's thought to have first emerged between 7000 B.C. and 2000 B.C., when hunter-gatherers abandoned their nomadic habits and created more permanent settlements. Recent analyses suggest that those first settlers came from South America and likely developed their staple food, maize, by 4000 B.C. Maize cultivation dramatically changed the Maya's trajectory, literally fueling the explosion of their society and culture."

    Spending time in space and having an unrivalled view of planet Earth is an experience many of us dream of, but the human body evolved to function in the gravity of Earth. So fully recovering from spending time in the weightlessness of space can take years.  

    “It’s a fact that space is by far the most extreme environment that humans have ever encountered and we’ve just not evolved to handle the extreme conditions,” Professor Damian Bailey, who studies human physiology, says. To begin with, the heart and blood vessels have an easier time as they no longer have to pump blood against gravity — and they start to weaken. And the bones become weaker and more brittle. There should be a balance between the cells breaking down old bone and those making new, but that balance is disrupted without the feedback and resistance of working against gravity. “Every month, about 1% of bones and muscles are going to wither away — it’s accelerated ageing,” Professor Bailey says. 

    Microgravity also distorts the vestibular system, which is how you balance and sense which way is up. In space, there is no up, down or sideways. It can be disorientating when you go up — and again when you return to Earth.

   By the middle years of the 20th century, the optimistic story of limitless progress through scientific and technological advance came to be rivalled and sometimes overshadowed by a much more pessimistic, even apocalyptic vision of the trajectory of the modern project. It began to seem increasingly possible that technology would come to master its creators and carry humanity toward unforeseen and possibly catastrophic outcomes.

   Premonitions of technological wizardry leading to disasters are extremely old, dating back at least to the myth of Icarus, who is said to have fatally fallen into the sea after flying too close to the sun on wings his father, Daedalus, constructed. As the Industrial Revolution gathered steam, dark anticipations became increasingly widespread, in works such as Mary Shelley’s Frankenstein; or, the Modern Prometheus and Karel Capek’s R.U.R. Perhaps technology, not man, was “in the saddle,” as Henry Adams worried. And perhaps machines, becoming ever more capable and interconnected, were the next step in the evolution of life, destined to dominate and eventually eliminate humanity, as Samuel Butler warned. The contours of the future, H. G. Wells announced in one of his famous lectures, “The Discovery of the Future,” were difficult to discern but would surely be unlike the past or the present, and definitely included disasters of new types and magnitudes.

   In the ghastly world wars, technological advances empowered barbarism on a new scale, destroying the credibility of the simple modernist faith that more potent tools are a straight path to human betterment. Rather, technological advance has produced a cornucopia of double-edged swords, with amplified possibilities for both progress and disaster. A growing herd of horsemen of the anthropogenic apocalypse have ominously appeared on the human horizon of possibility: nuclear weapons, genetic engineering, total surveillance despotism, runaway artificial intelligence, and rampant environmental decay.

   Premonitions of technological wizardry leading to disasters are extremely old, dating back at least to the myth of Icarus, who is said to have fatally fallen into the sea after flying too close to the sun on wings his father, Daedalus, constructed. As the Industrial Revolution gathered steam, dark anticipations became increasingly widespread, in works such as Mary Shelley’s Frankenstein; or, the Modern Prometheus and Karel Capek’s R.U.R. Perhaps technology, not man, was “in the saddle,” as Henry Adams worried. And perhaps machines, becoming ever more capable and interconnected, were the next step in the evolution of life, destined to dominate and eventually eliminate humanity, as Samuel Butler warned. The contours of the future, H. G. Wells announced in one of his famous lectures, “The Discovery of the Future,” were difficult to discern but would surely be unlike the past or the present, and definitely included disasters of new types and magnitudes.

   In the ghastly world wars, technological advances empowered barbarism on a new scale, destroying the credibility of the simple modernist faith that more potent tools are a straight path to human betterment. Rather, technological advance has produced a cornucopia of double-edged swords, with amplified possibilities for both progress and disaster. A growing herd of horsemen of the anthropogenic apocalypse have ominously appeared on the human horizon of possibility: nuclear weapons, genetic engineering, total surveillance despotism, runaway artificial intelligence, and rampant environmental decay.

Rain Is Coming to Burning Los Angeles and Will Bring Its Own Risks

    Rain is forecast to begin as soon as Saturday afternoon and to continue as late as Monday evening, says meteorologist Kristan Lund of the National Weather Service’s Los Angeles office. The area desperately needs the precipitation, but experts are warily monitoring the situation because rain poses its own risks in recently burned areas— most notably the potential occurrence of mudslides and similar hazards. “Rain is good because we’ve been so dry,” Lund says. “However, if we get heavier rain rates or we get the thunderstorms, it’s actually a lot more dangerous because you can get debris flows.”
    Fires do a couple of different things to the landscape that can increase the risk of burned material, soil and detritus hurtling out of control. When fires burn hot or long enough, they leave an invisible layer of waxy material just under the surface of the ground. This develops from decomposing leaves and other organic material, which contain naturally hydrophobic or water-repellent compounds. Fire can vaporize this litter, and the resulting gas seeps into the upper soil—where it quickly cools and condenses, forming the slippery layer.
    When rain falls on ground that has been affected by this phenomenon, it can’t sink beyond the hydrophobic layer— so the water flows away, often hauling debris with it. “All of the trees, branches, everything that’s been burned—unfortunately, if it rains, that stuff just floats,” Lund says. “It’s really concerning.” Even a fire that isn’t severe enough to create a hydrophobic layer can still cause debris flows, says Danielle Touma, a climate scientist at the University of Texas at Austin. Under normal conditions, trees and other plants usually trap some rain above the surface, slowing the water’s downward journey. But on freshly burned land there’s much less greenery to interfere; all the rain immediately hits the ground. [...]
    Fortunately, the rain should also help firefighters tame the blazes that remain active. The largest, the Palisades Fire, is currently 77 percent contained. The second largest, the Eaton Fire, is 95 percent contained. The Hughes Fire is third largest and only 56 percent contained. A fire can be fully contained but still burning. The containment percentage refers to the amount of the perimeter that has barriers that firefighters expect will prevent further spread.
