2nd grade - November 2012 - Reading


23. Let’s say that you are training for a certain race and your schedule calls for a 10 percent increase in mileage this week, yet you’re feeling a little pain in your legs.
How do you respond?
Do you go ahead and follow the schedule, or do you change it?
You know the right answer.
Yet many runners insist on sticking to the printed training schedule, since they believe that any change will ruin their chances of running a good race.
In fact, the opposite is true.
You would benefit more by giving your body a chance to recover.
Training schedules are built on the assumption that you aren’t experiencing any unusual pains before, during, or after the run.
If pain or fatigue does strike, don’t hesitate to change your workouts.
24. Most people don’t realize that both help and harm come from within ourselves.
Instead, they look to externals, attracted by appearances.
Wise people, on the other hand, realize that we are the source of everything good or bad for us.
They therefore don’t blame and accuse others.
They don’t convince people they are worthy, special, or distinguished.
If wise people experience challenges, they look to themselves; if they are praised by others, they quietly smile to themselves, unmoved; if they are criticized, they don’t feel the need to defend their name.
They exercise moderation in everything they do.
They know that they only have to watch out for themselves and the direction of their own desires.
25. When selling our ideas, we tend to “overpromise” in our enthusiasm for our creation.
In our vision of how we hope it will be, we leave no room for failure.
The result will probably be disappointing.
Not disastrous, but a little worse than expected.
No one will say anything, but they just won’t trust you quite as much next time.
Basically, you’ve blown it.
If instead you point out the possible weaknesses and how to resolve them, you are not only building a trusting relationship with your client but you’re able to solve any problems.
And if it does turn out the way you hoped, it is a bonus.
26. Marcia is a creativity coach.
One day an amateur artist came to see her because she had difficulty creating imaginatively.
The client always wanted to have a detailed plan of her work before she could begin.
Marcia offered a number of approaches but the client couldn’t commit to them.
Finally, she asked her client to play with her painting tools for thirty minutes every day for a week with absolutely no plan in mind.
She asked for more direction but Marcia told her there were no specific directions.
This was so far out of her comfort zone, but she did play and had a breakthrough.
Without a plan in mind, she created a piece that she liked.
27. The psychologist Gary Klein tells the story of a team of firefighters that entered a house where the kitchen was on fire.
Soon after they started hosing down the kitchen, the commander heard himself shout,
“Let’s get out of here!” without realizing why.
The floor collapsed almost immediately after the firefighters escaped.
Only after the fact did the commander realize that the fire had been unusually quiet and that his ears had been unusually hot.
Together, these impressions prompted that he called a “sixth sense of danger.”
He had no idea what was wrong, but he knew something was wrong.
It turned out that the heart of the fire had not been in the kitchen but in the basement below.
28. In prehistoric times, any attempt to harness nature meant forcing nature against her will.
Nature had to be challenged, usually with some form of magic or by means that were above nature ―that is, supernatural.
Science does just the opposite, and it works within nature’s laws.
The methods of science have largely taken away reliance on the supernatural ― but not entirely.
The old ways persist full force in primitive cultures.
They even survive in technologically advanced cultures too, sometimes disguised as science.
This is fake science ―pseudoscience.
The characteristic of a pseudoscience is that it lacks the key ingredients of science: evidence and having a test for wrongness.
In pseudoscience, doubts and tests for possible wrongness are firmly accepted.
29. The graph above shows the result of a recent survey in which more than 40,000 museum visitors of different age groups were asked how they prefer to experience museums.
Throughout all the age groups, audio tours are most preferred, followed by video clips, and then by computer interactions.
Compared to respondents in their 30s, respondents in their 60s are more than twice as likely to prefer audio tours.
When it comes to video clips, respondents in their 60s favor them more than any other age group.
As for the under-30 group, their preference for computer interactions is higher than that of respondents in their 40s.
Groups in their 50s and over show wider differences in preference between audio tours and computer interactions than the younger age groups.
30. Meteora, an area that attracts thousands of tourists from all over the world every year, is situated in central Greece.
Meteora is famous for its monasteries that are built on high rocks.
The name itself means ‘suspended in the air.’
In the past there were many monasteries but now only six are left.
The climate here varies from sweaty summers to chilly winters and the area experiences rain all through the year.
Tourists here can enjoy visiting monasteries, walking and exploring caves.
The best way to reach the place is by taking a bus from Athens.
The nearby places worth visiting are Mount Olympus, Kastoria, Thessaloniki and many more.
31. The essence of sports is competition.
However, it is in the best interest of professional sports clubs for this competition to occur on the playing field, not in the marketplace.
The reason is easily observable.
Imagine that sports clubs competed for fans in purely competitive markets.
The more successful clubs would sell more tickets and would naturally earn higher profits, which would allow these clubs to attract the best players through higher salaries.
Over time, these clubs would become so much stronger than
the less successful teams that competition on the playing field would become boring for spectators.
Weak teams would eventually be forced into bankruptcy, and strong teams would lose fans.
Therefore, a professional sports club’s economic decisions and those of its rivals are interdependent.
32. Someone who really loves us will be honest with us but will also tend to see us through rose-colored glasses.
Sandra Murray and her co-workers studied dating and married couples.
They found that the happiest were those who idealized each other, who even saw their partners more positively than their partners saw themselves.
When we’re in love, we’re biased to find those we love not only physically attractive but
socially attractive as well.
Moreover, the most satisfied married couples tend to approach problems without immediately criticizing their partners.
Honesty has its place in a good relationship, but so does presumption of the other’s basic goodness.
33. Thinking is hard work.
If you do not keep your working memory clear, then you are weakening your ability to think about what is going on in your class or meeting.
This might seem obvious, but if you look around the room at many meetings, you will find yourself face-to-face with one of the true demons of modern life: multitasking.
Sitting in a meeting, you will see that some people are taking care of work that is unrelated to the current meeting.
Others are checking their e-mail.
Still others are reading.
Each of these activities takes up your working memory.
You cannot maximize the quality of the new knowledge you are taking in if you do not give
yourself every opportunity to pay attention.
34. An option is forced if not choosing to decide is somehow equivalent in its consequences to choosing not to decide.
I recently debated buying a particular car that had just arrived at a local dealership.
I looked at it for two days and test-drove it twice.
I really liked it. It was an extraordinary deal because of some rare circumstances.
But, as much as I liked it, and as perfect a deal as it seemed, I couldn’t manage to form the positive belief that I should go buy it.
The situation was such that this was equivalent to deciding not to buy it, as my hesitation allowed another interested party to snatch it away while I pondered the possibilities.
If you are presented with a good job offer and given 48 hours to respond, then not choosing is equivalent in its consequences to a negative choice.
It is a forced option.
35. When you are asked what you are thinking about, you can normally answer.
You believe you know what goes on in your mind, which often consists of one conscious thought leading in an orderly way to another.
But that is not the only way the mind works, nor indeed is that the typical way.
Most impressions and thoughts arise in your conscious experience without your knowing how they got there.
You cannot trace how you came to the belief that there is a lamp on the desk in front of you, or how you detected a hint of irritation in your spouse’s voice on the telephone, or how you managed to avoid a threat on the road before you became consciously aware of it.
The mental work that produces impressions, intuitions, and many decisions goes on in silence in our mind.
36. Making $1 million in one year, but nothing in the preceding nine, does not bring the same pleasure as having the total evenly distributed over the same period, that is, $100,000 every year for ten years in a row.
The same applies to the inverse order ―making a bundle the first year, then nothing for the remaining period.
Somehow, your pleasure system will be saturated rather quickly.
As a matter of fact, your happiness depends far more on the number of instances of positive feelings, what psychologists call “positive affect,” than on their intensity.
In other words, good news is good news first; how good matters rather little.
So to have a pleasant life you should spread these small affects across time as evenly as possible.
Plenty of mildly good news is preferable to one single lump of great news.
37. If you can find a pattern, rule, or underlying principle in the material, you will likely be able to learn it more easily.
For example, if you arrange the number 376315374264 in four groups of three, it is easier to remember (376-315-374-264).
The task is even easier if you can see some patterns or relationships among the four groups.
The first three groups all start with 3, and the first and third groups both have a 7 next;
the second digits in the last two groups are only one digit apart (7 and 6), and the last digit is the same (4).
Noticing such patterns helps make the number more meaningful.
Similarly, looking for patterns in phone numbers, addresses, dates, or any other numbers will help you remember them.
38. In 1775, Typhoon Lengkieki crashed across Pingelap, an island near the equator and only about 20 out of the island’s 1,000 inhabitants survived.
In such situations, any rare genetic traits may spread.
One did.
The gene for total color blindness hid dormant in the DNA of the island’s ruler.
But as he and other survivors reproduced, and their children intermarried and reproduced, the rate of people with the gene on the island became much higher than in the outside world.
The first color-blind children on Pingelap appeared in the 1820s.
As they grew, it became apparent that they could not see colors and many could not distinguish letters.
The people of Pingelap began to call their color blindness maksun, meaning “not-see.” Pingelap
One interesting thing is that those with maksun have proved to be skilled at night fishing, as they are particularly adept at seeing the faint gray flashes of fish swimming in the dark.
39. E-tail is obviously a massive trend but in many ways online shopping is still divorced from the real world.
Online supermarkets are usually just text-based lists of products ―you can’t walk through the store.
Indeed, despite the convenience factor, online shopping has nothing in common with its real-world equivalent.
For example, online you generally have to know what you’re looking for and most people shop alone.
In the real world, however, shopping is more of an event, an experience that is usually shared, and customers listen to the recommendations of friends and trusted experts.
This hasn’t escaped the attention of some savvy Internet retailers and we are therefore starting to see the emergence of social shopping sites.
These are a mixture of search engines and social networking sites and allow shoppers to browse and buy based on other customers’ recommendations.
40. Other people’s views and troubles can spread like a virus.
Don’t damage yourself by adopting negative, unproductive attitudes when you talk with others.
If you encounter a sorrowful friend, or a colleague who has suffered sudden trouble, be careful not to be overcome by the misfortune.
Remember to discriminate between events themselves and your interpretations of them.
Remind yourself: “What hurts this person is not the occurrence itself but the response he
or she has uncritically adopted.”
We do a good service to others by remaining detached and avoiding melodramatic reactions.
Still, if you find yourself in a conversation with someone who is depressed, hurt, or frustrated, show them kindness and give them a sympathetic ear; just don’t allow yourself to be pulled down too.
요약문: When comforting your friends, try to keep psychological distance from their misfortune since their bad moods can influence you.
[41~42]
Several months ago, my daughter and I were taking a walk with a friend and her son.
My daughter was distracted by the sound of frogs, so she walked over to see several of them by he edge of the water.
“Look at the frogs by the pond!” she exclaimed excitedly, to which my friend replied,
“That’s not a pond, that’s a vernal pool.”
Perhaps I should be embarrassed to admit this, but I had no idea what a vernal pool was any more than my daughter did.
I realize that as a devoted naturalist and environmentalist, she was trying to help my child widen her knowledge of the natural world.
However, what happened was that my young child was confused and distracted from the important thing, which was admiring the frogs and their beautiful songs.
My friend’s good intentions of correcting my daughter’s error only prevented her from learning something more important on her own.
This is the way many of us unintentionally hinder opportunities in our everyday lives to help our children cultivate their minds.
Of course, we need to give our children the vocabulary they need to talk about the world around them.
However, we need to guard against our natural impulse to offer imprudent help to our children.
They need the time, the silence and the mental space to think and learn things for themselves.
[43~45]
My father was not an easy man but I knew that he loved me and took a strong interest in my education.
He placed a high value on his experience in the Navy and believed that a military-style education would be good for me.
So, in October of 1947, I attended fifth grade at Georgia Military Academy.
Watching me having a hard time with the tough students,
however, he soon took some pity on me and had me enrolled in a public school in the east of Georgia the following year.
It was great for me to be out of the confined boarding school environment and
I enjoyed being able to spend more of my free time outside and in nature.
But the brighter spot during that time was the arrival of a 21-year-old black man my father hired to take care of his new sailboat.
His name was Jimmy Brown.
On the day I first saw him, little did I know that he would be one of the most important men in my life.
My father did not think about hiring someone for his new boat when he bought it, indeed.
But soon, he realized that the new boat was going to be a lot of work and decided to
hire Jimmy after several friends recommended him as a capable handyman.
It did not take long for Jimmy to prove that my father’s friends were right about him.
My father trusted him more and more and allowed me to spend a lot of time with Jimmy.
Because of the time we spent together, we became really good friends.
Eventually, he became like a second father to me.
My father taught me many things, always showing his interest in my education.
But Jimmy taught me a lot more about nature.
I loved every minute of the time I spent with him and he became one of my best friends.
Because of my sincere friendship with him, I grew up without any prejudice.

Daejin - EBS Force Chapters 3 to 6


Queen Anne's Lace, a pretty, lacy-looking plant, may have white flowers in its natural state, but with your help, it can make an amazing transformation. Prepare some Queen Anne's Lace and cut off several blossoms with scissors, placing the flower stems directly into a jar with a little water in it. Next, gather some small containers and various shades of food coloring. In each container put about one part food coloring and two parts water. Once you've mixed the food coloring and water, place the stems of several blossoms of Queen Anne's Lace into each container of colored water and let them stand for several hours. Once the flowers are colored, you can make a bouquet by arranging your colored flowers in a vase with clear water.
 
A Japanese airline, All Nippon Airways(ANA), has started asking its passengers to visit the bathroom before boarding. ANA reasons that it can make passengers lighter, which in turn means lighter aircraft and reduced fuel use. The airline started the unusual policy on October 1st. ANA says that the policy was initially intended as an experiment lasting one month but it may expand the trial if results are positive. Flying is the fastest-growing source of carbon dioxide emissions, accounting for more than 600 million tons of the greenhouse gas per year. A flight between London Heathrow and New York's John F Kennedy airport creates around 1.35 tons of CO2 per passenger–more than one-third of the yearly emissions of an average person worldwide.
 
How do you measure the value of a candle? You can't measure its value by light output, since the candle has lost its function as a means of lighting a room. The years that followed Thomas Alva Edison's invention of the lamp might have been called "the fall of the candle and the rise of the light bulb." Yet every night all over America millions of candles are burning. No romantic dinner is complete without candles on the table. Individual candles are sold for $20 or $30 each, much more than a light bulb. Unlike an electric bulb, the value of a candle has no relationship to its light output. Like the fireplace and the sailing ship, the candle has lost its function and turned into art.
 
Everyone knows a school bus when they see one ― mainly by its color. That particular yellow has been the official school bus color for quite a long time. It dates back to 1939, when a professor named Frank W. Cyr, of Teachers College in New York City, organized a conference. His mission was to establish national safety standards for school buses. At that time, children were being transported to school in all sorts of vehicles, including trucks and horse-drawn wagons. Cyr's conference attracted transportation specialists from all across the country. Specialists from some paint companies came as well. After a week of discussion, the participants agreed on standards for bus construction and safety—and also for color. They determined that a particular shade of yellow-orange with black letters was the most visible combination in the early morning and late afternoon hours. They named that yellow color National School Bus Chrome.
 
"How can we provide the best health care for our people?" This is a question that every responsible society is attempting to answer. Advances in drugs and medical technology have made possible new treatments for diseases that medical science could not hope to cure before. In the wealthy countries, doctors and patients expect the latest drugs and technology. In the countries of the Third World, however, the health problems that have priority are very different. Here over 9 million children die annually from curable respiratory infections and from measles that has almost disappeared in the developed countries. In those countries, it is believed that about 80 percent of all cases of illness are the result of contaminated water and inadequate sanitation.
 
Once there was a poor man who had only potatoes to eat. Each dinner he would sit beneath his wealthy neighbor's kitchen window and breathe in mouth-watering aromas coming from the window. This seemed to lend flavor to his own plain meal. The wealthy man eventually discovered the poor man's habit. "This theft will not be tolerated!" he thundered. He dragged the poor man to a village elder for advice, and insisted that his neighbor pay for the privilege of enjoying the smells. The poor man said, "I cannot pay because all I own is my dog." "An equal exchange is a solution," said the village elder. "From now on, you shall be free to smell his dog whenever you wish."
 
Coconuts are said to be used in India to catch monkeys. People take a coconut and make a little hole just big enough for a monkey to put its paw through. And inside the coconut, which is nailed to a tree, they put something sweet. So the monkey smells something nice inside, and puts his hand in. He catches hold of the sweet inside, so now he has a fist. But the hole is too small for the fist to get out. When the hunters come back, the monkey's caught. But of course, all the monkey has to do is let go. Nobody's holding the monkey except the monkey's grasping greedy mind.
 
Russia thinks it can claim a huge chunk of the Arctic Ocean's floor by flying a flag at the North Pole. However, the Canadian prime minister said: "We've established a long time ago that this is Canadian property. You can't go around the world these days dropping a flag somewhere. This isn't the 14th or 15th century." This dispute is, of course, regarding oil. Experts believe about a quarter of the world's untapped oil and natural gas lies under the Arctic Ocean. Under the law of the sea agreement, a country can claim a larger section of the ocean bed if it can prove that it is an extension of its continental shelf. Russia says that the North Pole is an extension of the Eurasian continent. In 2001, this claim was rejected by the United Nations, but Russia is preparing to resubmit its claim.
 
According to a recent study, people who get a temporary or part-time job after retirement are more satisfied with their lives than those who stop working altogether. In the study, the retirees answered a basic mental health questionnaire. The findings showed that people whose post-retirement jobs were related to their previous careers reported better mental health. However, these mental health improvements were not found among people who worked in jobs outside their career field after retirement. This may be because retirees who take jobs not related to their career field may need to adapt to a different work environment and, therefore, become more stressed.
 
Recently, we had interviews with young men and women who talked about their most significant romantic relationships. An analysis of the interviews suggests that in well over half of the cases, the romance started between two people who had known each other previously. More often than not, the initial acquaintance was through work—"we worked at the same coffee shop," through school — "we sat next to each other in class," or through the place of residence — "we lived on the same floor." As the geographic distance separating potential couples decreased, the probability of their marrying each other increased.
 
Use it or lose it" is an old admonition. And it is also the conclusion of a new study by researchers at Stanford University. In the study the researchers studied 500 older runners, all of whom were in their 50s at the start of the project. The scientists tracked them for more than 20 years, comparing them to a similar group of non-runners. 19 years into the study, 34 percent of the non-runners had died compared to only 15 percent of the runners. Both groups became more disabled with age, but for the runners the onset of disability started an average of 16 years later. The study showed that the health gap between the runners and non-runners continued to widen even as the subjects entered their eighties.
 
Mistakes are a sign of life lived to the fullest. However, many people are fearful of taking action in their lives because they fear it will be a mistake. The paradox here is that you cannot avoid mistakes in life. The most successful people in the world have failed over and over again until they achieved their dream. Thomas Edison reportedly tried over 1,000 times to make the light bulb. When he was told that he had made 1,000 mistakes, he simply replied "I never failed. I just discovered 1,000 ways not to make a light bulb." A woman who moved to another town realized after a month that she had made a bad choice. However, the same situation could be looked at like this: She now had the opportunity to look for another, better position.
 
In recent years, I've learned that a failure to take regular breaks is an enormous mistake that not only wears you down over time, but actually makes you less productive. I assumed that by skipping my breaks, I'd be able to save a great deal of time and get more work done. Now I have an idea that more isn't always better. While you may not even feel it at the time, slowly but surely your exhaustion will sneak up on you. You'll become less patient and attentive, and your concentration and listening skills will suffer. You'll burn out much more quickly, and your creativity and insights will slowly fade away. You'd better push the "pause button" once in a while, and push the "replay button" returning to your work feeling refreshed.
 
In a research examining students studying for midterms and coping with stressful events, a psychologist Shelley Taylor compared the students who practiced mental rehearsal and focused on what they needed to do to succeed with those whose mental rehearsal focused strictly on the outcome they desired. Students who rehearsed the steps that they needed to take in order to get good grades and to deal with stressful experiences enhanced their performance more often than students who imagined themselves getting good grades and alleviating stress. So, when you focus on the process of achieving your goal rather than imagining the end product of your efforts, your chances of success will increase.
 
I know a teacher who once told her class, on the first day of school, that at the end of the year she would take them on a very exciting trip. Practically every day, students who were not behaving properly were threatened with the punishment of not going on the special trip. Many students even did extra work to make sure they would be included. During the last week of school, the teacher announced to the children that she was moving away and would not be able to take them on the trip after all. This betrayal not only ruined anything good she had done with the kids that year, but soured many of them on school and adults in general. A broken trust has to be avoided at all costs.
 
We are what we eat. The diet of the animals we eat has a connection with the nutritional quality of our food itself. This should be self-evident, yet it is a truth often overlooked by the food industry in its desire to produce vast quantities of cheap animal protein. That greed has changed the diet of most of our food animals from plants to seeds, because animals grow faster and produce more milk on a high-energy diet of grain. But some of our food animals, such as cows and sheep, are ruminants that evolved to eat grass. If they eat too many seeds, they become sick, which is why grain-fed cattle have to be given antibiotics. In their natural state, cattle spent their lives grazing on local grasses. Do not force them to eat against their natural preference.

Taerang Middle School Chapters 4 and 5


Hi, Minho. What are you up to?
Hi, Vicky. I was just looking at the website for the Latin Culture Center.
Oh, yeah? Did you find anything interesting?
Sure. The center has a museum, a garden, and a cafe. They sell Latin food in the cafe, too.
Wow! Where is it?
It's near City Hall, downtown. Would you like to go?
Why not? I'd like to do something different.
Great. How about this Saturday?
Fine with me. Why don't we meet at the bus stop?
OK. Can you make it at ten?
No problem. I'll meet you at the bus stop at ten.
How was your weekend, Minsu?
Great! I went to the German Village in Namhae-gun with my family.
There's a German Village in Namhae-gun? Can you tell me more about it?
In the 1960s, a lot of Korean nurses and miners went to Germany to work.
Some of them got married to German people and decided to stay there.
In 2005, however, some land in Namhae-gun was offered to them at a cheap price.
So they came back to Korea and built German-styled houses.
What an interesting story! Can we experience foreign cultures in any other places in Korea?
I think so. We could find more information on the Internet.
That's a good idea!
Very near the Incheon subway station, you can find the gate to Chinatown.
Houses there are made with a combination of Chinese and Korean styles, and shops are decorated with Chinese paintings.
The restaurant area is the home of jajangmyeon, a favorite Chinese food for many Koreans.
Do you want to know how to make jajangmyeon noodles?
If so, don't miss the Jajangmyeon Festival held in October.
During the festival, you can enjoy not only the Noodle Making Show but also other events like the Jajangmyeon Eating Contest and performances by the Chinese Circus.
Do you know where to experience French culture?
Seorae village in Seoul is a great place to go to.
In the Village's cafes and restaurants, you can hear people speaking French.
There is a French school as well as Montmartre Park.
The park was named after the famous hill in Paris.
If you are interested in French music, visit Seorae Village in June for the Korean-French Music Festival.
During the festival, you may run into a marching band or see French school students doing special performances.
Wow! We can learn about foreign cultures in many different places in Korea.
Uh huh. And there's more. Look at this!
Isn't that a mosque?
Yeah! It's located in Itaewon, Seoul.
Really? I've never visited a mosque before.
Then let's go to Itaewon this weekend.
We can get some lamb kebabs at one of the restaurants in front of the mosque.
Great! I can't wait!
This is a little gift for you, Suji.
Thank you, Jake. That's very nice of you.
Oh, it's nothing. Don't mention it.
Wow! You painted a picture of me! I love it! Are you taking art classes after school?
No. But I read a book about Paik Namjune. He said anybody can create art.
Paik Namjune? Oh, I know him. I saw some of his work in an art museum.
Did you find it interesting?
Yes, it was very interesting. If you're interested, we can go to the art museum together.
Really? I'd love to go! How about this weekend?
Great!
What can you do with a television set?
You might think this is a stupid question.
Televisions are for watching, right?
You can watch news or movies on your TV.
Paik Namjune, however, used televisions in a very different way: to create art.
He used television sets in his art by making them into other things such as chairs, robots, gardens, and even a house!
Paik Namjune was born in Korea in 1932, but he lived in several other countries such as Japan, Germany, and the U.S.A. over the course of his life.
He studied music at first, but he became interested in combining video and music.
He especially wanted to use television sets in his performance art so that he could show the music instead of just playing it.
In 1965, he had his first solo exhibition Electronic Art in New York.
He used different techniques so that he could create new moving images that no one had seen before.
People were surprised by his ideas and he became famous.
Now he is known as the father of video art.
One of his famous pieces is Internet Dweller: btmj.twelve.jhgd ― the twelfth in his Internet Dweller series.
The title is written in the form of an Internet address, and "btmj" and "jhgd" are letters taken from his friends' names.
This piece of art is made from things that we can easily find around us.
For example, the face is made from two television cabinets.
TV screens are used for the eyes and the mouth.
A large camera lens is used for the nose.
Two clocks are used for the ears.
What about the light bulbs on top?
Maybe they represent "bright ideas." What do you think?
The more the Better is another famous work by Paik Namjune.
He made this great tower of televisions to celebrate the Seoul Olympics in 1988.
Each screen showed colorful scenes of Korean nature or culture.
The number of screens in the tower, 1003, was picked to represent the date October 3, Gaecheonjeol (National Foundation Day of Korea).
The tower looks like a birthday cake, doesn't it?
Many people may think art is difficult to understand, but Paik Namjune thought art should be fun and easy to enjoy.
He used his art to express his sense of humor and imagination.
You can see more of Paik Namjune's works of art on the right.
Take a look at each picture and try to guess their titles!
Look at the swimmer in the second lane! He is as fast as a fish.
Yeah. He's going to win the race.
By the way, do you know why there are lane dividers in swimming pools?
Well, I don't know. Why?
Because lane dividers help the water stay smooth.
What do you mean?
If there were no lane dividers, the water would become rough. Lane dividers break up the waves other swimmers create and make the water calm.
Oh, I get it. I didn't know science was so important in sports.
Yeah. I want to learn more about the science of sports.
So do I.
There are many forces around us.
You can learn about one of them through this simple experiment.
Put a coin into a clear balloon.
Make sure that the coin goes all the way into the balloon.
Blow up the balloon until it is almost clear in the middle and cloudy at the areas near the neck and the top.
If the balloon is completely clear, it has too much air in it.
Tie off the balloon, and you are ready to go.
Hold the balloon with your hand.
The neck of the balloon will be in your palm.
Your fingers should be holding the sides of the balloon and your palm should face the ground.
Spin the balloon around for a few seconds and then stop it.
The coin may bounce around at first, but it will soon begin to roll around inside the balloon.
Your coin should continue to spin for 30 seconds or more.
Do you know what makes the coin spin?
This experiment shows the effects of a special force on the coin.
The force is the inward force on an object that causes it to move in a circle.
For example, tie a ball to a string and hold the end of the string.
Swing it around, and you will be able to feel the force.
You can find more examples of it in your everyday life.
