Introduction by Indira Nair, Carnegie Mellon’s Vice Provost for Education:

Hi. Welcome. It’s my pleasure to introduce you to the first of our new university’s lectures titled
Journeys . lectures in which members of our community will share with us reflections and insights
on their personal and professional journeys. Today’s Journey’s lecture as you all know is by
Professor Randy Pausch. The next one is on Monday, September 24th by Professor Roberta Klatzky.

To introduce Professor Randy Pausch, our first Journeys speaker, I would like to introduce Randy’s
friend and colleague, Steve Seabolt. Steve has been at Electronic Arts for six years and is the Vice
President of Global Brand Development for The Sims label at Electronic Arts. As you all know, The
Sims is one of the most, if not the most successful PC games in the world, with sales approaching
over $100,000,000. Prior to that, Steve was the Vice President for Strategic Marketing and
Education at EA, bridging academia and Electronic Arts. His goal was to work with academics so
there was an effective educational pathway for kids with building games as their dreams. It was in
that role that Randy and Steve became colleagues and friends. Before Electronic Arts, Steve was the
worldwide Ad Director for Time Magazine and CEO of Sunset Publishing, which is a very favorite
magazine in the Southwest, and as CEO there, one of the things he started was school tours,
because like Randy he shares a passion for inspiring kids of all ages to share their excitement for
science and technology.

So to introduce Randy, his friend Steve Seabolt. Steve?

[applause]

Steve Seabolt, Vice President of Worldwide Publishing and Marketing for Electonic Arts (EA):

Thank you very much. I don’t mean to sound ungracious by correcting you, but given that our PR
people are probably watching this on webcast, I’d catch heck if I went home and didn’t say that it

We have all heard the expression "it's raining cats and dogs." There are several theories about this rainfall saying. It is possible that the word cat is derived from the Greek word 'catadupe' meaning 'waterfall.' Or it could be raining 'cata doxas,' which is Latin for 'contrary to experience,' or an unusual fall of rain.

In Northern mythology the cat is supposed to have great influence on the weather, and English sailors still say the cat has a gale of wind in her tail when she is unusually frisky. Witches that rode upon the storms were said to assume the form of cats; and the stormy northwest wind is called the cat's nose in the Harz mountains even at the present day. The dog is a signal of wind, like the wolf. Both animals were attendants of Odin, the storm-god. In old German pictures the wind is figured as the "head of a dog or wolf," from which blasts issue. The cat therefore symbolizes the down-pouring of rain, and the dog the strong gusts of wind that accompany a rainstorm; and a rain of "cats and dogs" is a heavy rain with wind.

Image of a black cat.The Bible describes a rain of manna and quails more than 3,000 years ago. At the time this was looked upon as a supernatural event; it was actually not an uncommon thing. The rain of manna has happened frequently in modern times; the manna is really a lichen that grows in great numbers after rains.

There are numerous accounts of rains of frogs, hay, fish, and grain. All of these accounts seem to be due to tornado-like "whirlwinds." A good whirlwind can lift thousands of pounds and carry objects for miles. There is one  reliable account of a fishing boat that sailed into a large waterspout. Fish flew everywhere. There are about seventy recorded rains of fish, but nearly all of the rains of fish are small one s. There is, however, one  account of a fish fall in India in which more than ten people picked up fish weighing up to eight pounds each. There are many accounts of rains of ice-coated ducks, grasshoppers, fish, and frogs, but there is no account of a raining of cats and dogs (Lockhart, 1988).

 Raining animals


Raining animals is a relatively rare meteorological phenomenon, although occurrences have been reported from many countries throughout history. One hypothesis that has been furthered to explain this phenomenon is that strong winds travelling over water sometimes pick up debris such as fish or frogs, and carry them for up to several miles.[1] However, this primary aspect of the phenomenon has never been witnessed or scientifically tested.

The animals most likely to drop from the sky in a rainfall are fish and frogs, with birds coming third. Sometimes the animals survive the fall, especially fish, suggesting the animals are dropped shortly after extraction. Several witnesses of raining frogs describe the animals as startled, though healthy, and exhibiting relatively normal behavior shortly after the event. In some incidents, however, the animals are frozen to death or even completely encased in ice. There are examples where the product of the rain is not intact animals, but shredded body parts. Some cases occur just after storms having strong winds, especially during tornadoes.

However, there have been many unconfirmed cases in which rainfalls of animals have occurred in fair weather and in the absence of strong winds or waterspouts.

Rains of animals (as well as rains of blood or blood-like material, and similar anomalies) play a central role in the epistemological writing of Charles Fort, especially in his first book, The Book of the Damned. Fort collected stories of these events and used them both as evidence and as a metaphor in challenging the claims of scientific explanation.

explanations

French physicist André-Marie Ampère was among the first scientists to take seriously accounts of raining animals. He tried to explain rains of frogs with a hypothesis that was eventually refined by other scientists. Speaking in front of the Society of Natural Sciences, Ampère suggested that at times frogs and toads roam the countryside in large numbers, and that the action of violent winds can pick them up and carry them great distances.[2]

More recently, a scientific explanation for the phenomenon has been developed that involves waterspouts. In effect, waterspouts are capable of capturing objects and animals and lifting them into the air. Under this theory, waterspouts or tornados, transport animals to relatively high altitudes, carrying them over large distances. The winds are capable of carrying the animals over a relatively wide area and allow them to fall in a concentrated fashion in a localized area.[3] More specifically, some tornados can completely suck up a pond, letting the water and animals fall some distance away in the form of a rain of animals.[4]

This hypothesis appears supported by the type of animals in these rains: small and light, usually aquatic.[5]. It is also supported by the fact that the rain of animals is often preceded by a storm.

 

In the case of birds, storms may overcome a flock in flight, especially in times of migration. The image to the right shows an example where a group of bats is overtaken by a thunderstorm.[6]. The image shows how the phenomenon could take place in some cases. In the image, the bats are in the red zone, which corresponds to winds moving away from the radar station, and enter into a mesocyclone associated with a tornado (in green). These events may occur easily with birds in flight. In contrast, it is harder to find a plausible explanation for rains of terrestrial animals; part of the enigma persists despite scientific studies.

In some cases, scientific explanations deny the existence of rains of fishes. For example, in the case of a rain of fishes is Singapore in 1861, French naturalist Francis de Laporte de Castelnau explained that the supposed rain took place during a migration of walking catfish, which are capable of dragging themselves over the land from one puddle to another. [7] Thus, he argued that the appearance of fish on the ground immediately after a rain was easily explained, as these animals usually move over soft ground or after a rain.

 Raining cats and dogs

The phrase "raining cats and dogs" is of unknown etymology.[8] A number of improbable folk etymologies have been put forward to explain the phrase,[9] for example:

  • In 16th century Europe when peasant homes were commonly thatched, the home was constructed in such a manner that animals could crawl into the thatch and find shelter from the elements, and would fall out during heavy rain.
  • Drainage systems on buildings in 17th century Europe were poor, and may have disgorged their contents during heavy showers, including the corpses of any animals that had accumulated in them. This occurrence is documented in Johnathan Swift's 1710 poem 'Description of a City Shower', in which he describes "Drowned puppies, stinking sprats, all drenched in mud,/Dead cats and turnip-tops come tumbling down the flood."
  • The Greek word Katadoupoi, referring to the waterfalls on the Nile,[8] sounds similar to "cats and dogs"
  • The Greek phrase "kata doksa", which means "contrary to expectation" is often applied to heavy rain, but there is no evidence to support the theory that it was borrowed by English speakers.[8]

정부 “수능대체 영어시험, 현실적으로 불가능"

대통령직 인수위가 올해 초 발표했던 "영어능력 평가시험으로 수능 영어성적 대체하겠다"는 방침이 사실상 유보된 것으로 알려졌다.

인수위는 당초 현재 중학교 2학년 학생들이 대학에 들어가기 위해 치르는 2013학년도 대학 입시에서 영어 과목을 폐지하고 영어 능력 평가시험 성적을 대신 제출하게 하겠다는 방침을 발표한 바 있다.

정부의 한 관계자는 17일 "수능 영어 과목을 국가 영어 자격시험으로 대체하는 방안을 추진했지만 이럴 경우 사(私)교육비가 너무 들어가게 된다는 여론이 높아 일단 보류하는 것으로 의견을 모았다"고 밝혔다.

당초 정부가 수능 대신 추진했던 영어 능력 평가시험은 토플처럼 읽기?듣기?말하기?쓰기의 4개 영역을 평가한다. 평가 첫해인 2013학년도에는 읽기와 듣기만을 평가하고, 2015학년도부터는 읽기?듣기?말하기?쓰기 4개 영역을 평가한다는 게 올해 초 대통령직 인수위원회의 발표 내용이었다. 대통력직 인수위원회는 이를 통해 회화와 실용영어 중심으로 영어교육을 개편하는 한편 학생들의 영어공부 부담을 줄여주겠다는 방침을 내세웠다

하지만 최근 교육과학기술부 등에서 영어 능력 평가시험에 대해 검토한 결과 55만여명의 수험생들이 동시에 듣기 시험을 치르는 데 장소와 장비등의 면에서 기술적 문제가 있었으며 또한 수능시험을 주관하고 있는 교육과정평가원에서도 "영어 능력 평가시험과 수능시험은 서로 대상으로 하는 시험범위나 대상인원이 달라 혼란이 가중될 것"이라는 반대의견을 보내온 것으로 알려졌다.

교과부는 공청회등을 통해 이 문제에 대해 12월까지 계속 논의해보겠다는 방침이지만 부정적인 의견이 많아 계속 추진하기 어렵다는 의견이 지배적인 것으로 알려졌다.

한편, 이번 영어능력평가로 수능대체 유보 방침에 의해 인수위가 올해 초 수능시험과 관련해 공약한 두가지 방침이 모두 현실화 되지 못하게 될 전망이다. 당초 인수위는 사회ㆍ과학 탐구과목을 1과목으로 축소하겠다고 발표했지만 평가원은 이를 "(현행 4과목)에서 3과목으로 1과목 축소"쪽으로 방향을 잡아 교과부에 의견을 통보한 바 있으며, 영어 과목 역시 수능시험 영어 폐지를 천명한 바 있으나 유보될 전망이다. 김재현 기자/madpen@heraldm.com

수능 영어 대체할 '한국형 토플' 유보
[조선일보 2008-11-17 06:10]
정부 "사교육 부추길 우려"

현재 중학교 2학년 학생들이 대학에 들어가기 위해 치르는 2013학년도 대학 입시에서 영어 과목을 폐지하고 영어 능력 평가시험(한국형 토플) 성적을 대신 제출하게 하려던 정부 방침이 사실상 유보됐다.

수능 영어 과목이 현행대로 유지됨에 따라 현재 중2 학생들은 듣기와 지필고사 위주의 수능식 영어 시험을 그대로 준비해야 한다.

정부의 고위 관계자는 16일 "수능 영어 과목을 국가 영어 자격시험으로 대체하는 방안을 추진했지만 이럴 경우 사(私)교육비가 너무 들어가게 된다는 여론이 높아 일단 보류하는 것으로 의견을 모았다"고 밝혔다.

당초 정부가 수능 대신 추진했던 영어 능력 평가시험은 토플처럼 읽기·듣기·말하기·쓰기의 4개 영역을 평가한다. 평가 첫해인 2013학년도에는 읽기와 듣기만을 평가하고, 2015학년도부터는 읽기·듣기·말하기·쓰기 4개 영역을 평가한다는 게 올해 초 대통령직 인수위원회의 발표 내용이었다.

하지만 최근 교육과학기술부 등에서 한국형 토플에 대해 검토한 결과 55만여명의 수험생들이 동시에 듣기 시험을 치르는 데 장소와 장비 등의 면에서 기술적 문제가 있고, 이 시험을 실시할 경우 사교육 규모가 더 커질 것이라는 예상이 나와 '유보' 쪽으로 가닥을 잡았다는 것이다.

이로써 정부가 정권 초 대입정책을 대폭 바꾸겠다고 발표해놓고 불과 1년도 안 된 시점에서 원 상태로 되돌려 학생과 학부모들을 혼란에 빠트렸다는 비판을 면할 수 없을 것으로 보인다.

 (安貧樂道) being content amid poverty and taking pleasure in acting in an honest way

 
Poverty and positivity
 
November 06, 2008

Poverty is destitution, known as bingung in Korean. However, the two are slightly different. Bin means dispersal of wealth and is composed of the Chinese character pae (money), placed below bun (dividing).

On the other hand, gung is composed of hyeol (a small hole) with a character that means “body” and refers to extreme poverty.

According to the dictionary, “bin” means “not possessing wealth” and “gung” means “having no way out.”

If we combine the two, it means not having anything to eat and live on so that one can’t go any further.

Such poverty is very dangerous to people.

One is desperate, because there is nothing to eat or live on and brings grief. Efforts taken to relieve poverty may be at the root of all human behavior since the beginning of history.

Therefore, efforts to fight poverty have always been made.

In China, it was common to call in the wealth deity during major holidays. To this day, the custom of chasing away the ghost that brings poverty and calling in the wealth deity is still widely held.

What shall we do if poverty lingers on even when we try to chase it away?

Appreciating it is one option. Yang Xion (53-18 B.C.) of the Western Han Dynasty, wrote poetic prose to chase away poverty. He said of poverty, “You follow me even when I dump you and go up to the top of Mount Kunlun ... and you follow me even when I hide myself in a cave on a mountain.”

Poverty refutes him in the prose, “Having attended the king [during difficult times] and endured in humble homes ... you have gained great virtue [thanks to poverty] and yet you only resent me.”

Yang Xion then realizes that his literary fame is the result of having overcome destitution in the past.

Linking “contentment with poverty and delight in Taoism” emanates from this.

The oft-heard maxim “The more destitute we are, the firmer our integrity becomes,” is born from the positive thinking that sees today’s poverty and destitution as the ground for a good tomorrow.

Making ends meet in each household is becoming much more difficult nowadays. Even if we try to chase destitution away, it sticks to us.

We must think of the present as an opportune time to make efforts to prepare for a hopeful tomorrow.

The writer is a deputy international news editor of the JoongAng Ilbo.

Barack Obama (wikipedia)
http://en.wikipedia.org/wiki/Barack_H_Obama

Barack Hussein Obama II (pronounced /bəˈrɑːk hʊˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the junior United States Senator from Illinois and President-elect of the United States of America.[1]

Obama is the first African-American to be president of the United States.[2] A graduate of Columbia University and Harvard Law School, where he became the first black person to serve as president of the Harvard Law Review, Obama worked as a community organizer and practiced as a civil rights attorney before serving three terms in the Illinois Senate from 1997 to 2004. He taught constitutional law at the University of Chicago Law School from 1992 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, he announced his campaign for the U.S. Senate in January 2003. After a primary victory in March 2004, Obama delivered the keynote address at the Democratic National Convention in July 2004. He was elected to the Senate in November 2004 with 70 percent of the vote.

As a member of the Democratic minority in the 109th Congress, he helped create legislation to control conventional weapons and to promote greater public accountability in the use of federal funds. He also made official trips to Eastern Europe, the Middle East, and Africa. During the 110th Congress, he helped create legislation regarding lobbying and electoral fraud, climate change, nuclear terrorism, and care for returned U.S. military personnel. Obama announced his presidential campaign in February 2007, and was formally nominated at the 2008 Democratic National Convention with Delaware senator Joe Biden as his running mate.

http://en.wikipedia.org/wiki/Dessert_wine

Dessert wines (or pudding wines BrE) are sweet wines typically served with dessert, such as Sauternes and Tokaji Aszú. Despite the name, they are often best appreciated alone, or with fruit or bakery sweets. There is no simple definition of a dessert wine. In the UK, a dessert wine is considered to be any sweet wine drunk with a meal, as opposed to the white fortified wines (fino and amontillado sherry) drunk before the meal, and the red fortified wines (port and madeira) drunk after it. Thus most fortified wines are regarded as distinct from dessert wines, but some of the less strong fortified white wines, such as Pedro Ximénez sherry and Muscat de Beaumes-de-Venise, are regarded as honorary dessert wines. In the United States, by contrast, a dessert wine is legally defined as any wine over 14% alcohol by volume, which includes all fortified wines - and is taxed more highly as a result. This dates back to a time when the US wine industry only made dessert wines by fortification, but such a classification is outdated now that modern  yeast and viticulture can produce dry wines over 15% without fortification, yet  German dessert wines can contain
                                             half that amount of alcohol.

모르는 어휘가 많을거예요~ wine에 관한 용어가 많아서...

 Video Game Violence

 

PRE-READING QUESTIONS

 

1. Do you ever play video games? If so, how often do you play?

2. Do you have children? Do they play video games and if so, how often do they play?

3. What do you think is the average amount of time school age children in America play video games every day?

4. Do you think most popular video games contain violence?

5. Is there a law in your country (city, state, province, etc.) restricting the sale or rental of violent video games?

6. Who do you think might support this kind of law and who do you think might oppose it?

 

Video Game Violence

 

Many school-age children in the United States play video games for close to an hour a day. Almost 90% of the most popular video games contain violence, and much of it is extremely violent.

 

The video game industry rates games that contain violence or sexual images as “"M”" for mature audiences. Researchers have discovered, though, that children as young as seven years old have played these games.

 

In July 2005, the state of Illinois passed a law that makes it illegal to sell or rent a video game containing violence or sexual images to anyone under 18 years of age. Those who break the law face a year in prison or a $5,000 fine. The video game industry must label these games as “"violent”" or “"sexually explicit.”"

 

Many parents and researchers support this law. They believe that children who play violent video games may act more violently in real life. They also believe that the industry is more interested in making money than protecting children from the harmful effects of seeing violent or adult sexual images.

 

Those who sell or rent video games oppose the law. They think that parents, not video stores, should be responsible for what their children are doing or seeing.

 

In the past, similar laws have been rejected by American courts, mainly on the basis of free speech. Illinois lawmakers think that their law will be more successful because they have dealt with many of the courts’' concerns. They also think that it is time for the courts to deal more seriously with the harmful impact of these games on children.

 

In addition to the law, the state will set up a Web site where parents can learn how these games may affect their children. Parents can also report stores that continue to sell or rent these games to minors and companies that have not labeled their games properly.

 

COMPREHENSION QUESTIONS

 

1. How can someone know if a video game contains violence or sexual images?

2. What kind of law did the state of Illinois pass in 2005 regarding video games?

3. Why do many parents support this law?

4. What do many people who rent or sell video games think about this law?

5. What will the punishment be for someone who breaks this new law in Illinois?

When Training Backfires: Hard Work That’s Too Hard

By GINA KOLATA

Published: September 3, 2008

UNTIL last spring, running was going great for 15-year-old Erik Kraus. He had been training hard without a break for 18 months and was becoming faster and faster.

Skip to next paragraph
Filip Kwiatkowski for The New York Times

RSS Feed

Filip Kwiatkowski for The New York Times
Filip Kwiatkowski for The New York Times

Then, when spring track started, something went awry. Every time he raced 1,500 meters, his time was 15 seconds slower than in the previous race.

Erik’s father, Dr. William Kraus, a runner himself and a cardiologist at Duke University who studies exercise, was concerned. Erik was tired all the time; his legs felt heavy; he was frustrated, irritable. Could it be the condition that athletes dread: overtraining?

Overtraining is the downside of training, the trap that can derail an athlete’s success. It’s a real physical condition caused by pushing too hard for too long. It can happen with too much exercise, too much intense exercise, or both. Its hallmarks are poor performances, exhaustion and apathy.

“You just feel bad,” said Dr. William O. Roberts, an internist at the University of Minnesota who specializes in treating athletes and is a former president of the American College of Sports Medicine. “The spark is gone.”

It can come on so insidiously that before athletes know it, they find themselves trapped in a downward spiral. The harder they train, the worse they do.

But there’s another trap — the overdiagnoses of overtraining, said Dr. Steven Keteyian, the director of preventive cardiology at Henry Ford Hospital in Detroit.

Dr. Keteyian, who has written textbook chapters on the condition, cautions that it is quite rare. But many athletes worry about overtraining every time they fail to perform as well as they think they should.

“It doesn’t happen over a two-week period of time,” Dr. Keteyian said. And it is unlikely to strike someone running 20 miles or so a week or doing the equivalent amount of another endurance sport, he said.

“Twenty miles is nothing,” Dr. Keteyian said. “Talk to me when you are running 50 miles a week. If you are a runner and have a steady history of running 40 to 70 miles a week and now you are pushing it to 80, 90, 100 miles a week and your times are dropping and you are feeling sluggish, then I’ll start to listen.”

If overtraining has occurred, “it’s a long road back,” Dr. Keteyian said. The only cure is to take weeks or months off. No athlete wants that, Dr. Keteyian said, so it’s important not to jump to conclusions.

Dr. Kraus knew that overtraining was unlikely. But his son seemed to meet the criteria, such as they are. He began looking for credible data on overtraining but was soon disappointed to discover that overtraining remains poorly understood and understudied.

There is no definitive test for overtraining. Instead, the diagnosis is reached by exclusion. Besides slower times and fatigue, Dr. Keteyian and others say athletes may notice that their muscles are weaker and that their coordination is poorer. Their heart rates may be higher than they should be with moderate exercise. And their resting heart rates, taken first thing in the morning, can be higher, too.

Overtraining is an unintended consequence of the only known way for athletes to improve — by pushing their bodies and stressing themselves by deliberately going faster or longer than feels comfortable. “Training a little bit beyond your capabilities is the only way to get better,” Dr. Kraus said. “But you have to balance that with rest and recovery. It’s a fine line. Where is that edge and how do you get as close as possible without going over it?”

Elite athletes and their coaches are acutely aware of overtraining, said Frank Busch, the head coach for the University of Arizona’s swimming team and an assistant coach for the United States men’s Olympic swimming team. And they have become adept at heading it off.

Not too long ago, coaches thought that volume — hours upon hours of training — was the key to outstanding performances, Mr. Busch said. “The result was sort of an arms race among swimmers and other endurance athletes to see who could train the most,” he said. “Athletes began getting overtrained.”

Now coaches and swimmers know that there is a point of diminishing returns. Coaches look for signs that their athletes are doing too much. Performance is one indicator, of course, but so is something as simple as a swimmer who has stopped smiling, Mr. Busch said. “That’s usually a sign that they are dreading practice or there is something else going on. Maybe they are exhausted around the clock.”

Dr. Roberts said that among his recent overtrained patients was a young man who was a stellar Nordic skier. A year and a half later, in marched another: the man’s mother, a middle-aged woman, also a prize-winning Nordic skier.

“They both trained too hard,” Dr. Roberts said. Both, he added, “were more or less self-coached at the time.” No one was monitoring them.

“Athletes are obsessed and gullible,” Dr. Keteyian said. “They will do anything they can to improve their performance and they don’t know when to stop.”

Dr. Roberts suggested that athletes who feel tired all the time first take some time off from their sport, perhaps a few days to two weeks. If they still do not feel better, they should see their primary-care doctor and mention that they are concerned about overtraining. Or, he said, they might want to seek out a physician who specializes in sports medicine — a list is available on acsm.org.

“An athlete would want to look for a physician who practices the broader scope of sports medicine and has not limited his or her practice to musculoskeletal problems,” Dr. Roberts added.

As for Dr. Kraus, he told his son to take a two-week break. That did not help. He had the youth tested for ferritin, an iron storage protein. Overtrained athletes can have low iron levels and anemia, although overtraining is not the only cause.

But even though Erik’s ferritin levels were sub par, and even though they rose slightly when he took iron supplements, he felt as tired and sluggish as ever. In the end, Erik Kraus ended up taking two months off. It was not easy. Like other athletes, he wanted to train, wanted to race, and he worried that he would never be competitive again. Now, finally, he has returned to running.

“When he first started back, he said, ‘Oh, my gosh, this feels good,’ ” Dr. Kraus recalled. Then Erik went for an eight-mile run with the fastest runner on his team. He not only kept up with his teammate but pushed him at the end.

Erik returned home from that run all smiles. “He said, ‘Dad, I had a breakthrough today,’ ” Dr. Kraus said.
