The 10th of November, Tuesday. Spring Pool is the name of a glass factory near the end of Neo-poo Rd., Hsinchu. Today, 3 classes from our school, the 8th grade art, the Chinese culture, and the art core class, which is the class that I'm in, went to visit Spring Pool. In the factory, I realized that there were only a several of workers, but many running machines. We had a tour going through the factory. We saw professional glass workers blowing glasses, and also making animals out of glasses. It was quite impressive that the worker could make a penguin out of glass in less than 5 minutes.

Because of the machines, the paths in the factory seemed quite narrow, however, every workers were being very careful in the environment. I've noticed that every workers were wearing gloves. Also, I've noticed, from each of their face expressions, that they were all very concentrated on their works. Further on, the works in the factory seemed to be divided. Workers had different jobs, and were to be responsible for each of their individual jobs. For example, I saw about 5 people working on a cup-making machine, and 2 women, standing near the gate of the factory, making sure that the surface of certain glass productions were even. As a result, even though I may not understand all the jobs that the workers were doing, but I could tell that they were all working together.

After the tour, we went to a room where they exhibit completed glass works, including cups, vases, goblets, and glass-made-arts. In the room, we met the manager of the factory. Through the manager's introduction about the factory, we were informed that the factory uses recycled, and reuses glasses. Also, we were informed that the typical style of glass-made-arts from the factory is things that are related to traditional Chinese culture. For example, a glass-made-Li Yu. And moreover, our tour, a professional glass maker called Joy Huang, explained the reason of why Hsinchu is famous for its manufacturing of glass. She said, 'Because of the resources of natural gas and silicon(glass sand), the government chose Hsinchu to produce glasses.'

This was an interesting experience of looking at the process of how the glass productions, such as cups that we use everyday, were made. Also, it's interesting to see how is it like to work in a glass factory, how does glass turn into different shapes, and especially, how glasses were blowen up like a balloon!

The resent winners of the Nobel Prize, for studies of the structure and function of the ribosome in 2009, are Venkatraman Ramakrishnan of the M.R.C. Laboratory of Molecular Biology in Cambridge, England; Tmas A. Steitz of Yale University; and Ada E. Yonath of the Weizmann Institute of Science in Rehovot. These scientists showed how the information encoded on strands of DNA is translated into the thousands of proteins that make up living matter. Dr. Yonath set out to understand the detailed structure of the ribosome by growing crystals of the ribosome material from deserted bacteria known as Grobacillus stearothemophilus and then irradiate it with X-rays. Meanwhile, she has drawn others into the field, including Dr. Steitz. Dr. Steitz solved a key problem on how to explain the dots in the diagram of the large sub unit, aided by electron microscope images of the ribosome. Meanwhile, Dr.Ramakrishnan decoded the structure of the other half of the ribosome, which was the so-called small sub unit.

'At least 529 people are now known to have died in a powerful quake that struck the Indonesian island of Sumatra on Wednesday, the government says.' -- BBC

A 7.6-magnitude quake struck close to the city of Padang, the capital of West Sumatra province in of Indonesia. The earthquake has brought down hospitals, schools and shopping malls, cut power lines and triggered landslides. More than 400 people have been seriously injured, and the death toll is expected to rise.

The first earthquake of 7.6 struck at 5:16PM local time (10:16AM GMT) on the 30th of September, Wednesday. One of the biggest damage was a collapse of school in Padang. Police said that nine children had been found alive, yet that eight bodies had also been pulled from the rubble so far. And even moreover, David Lange, a doctor with Surfaid International, told the BBC one that of the hospitals was 'completely destroyed'. Then, on the next day, the 1st of October, Thursday, the second earthquake of 6.8 struck close to Padang at 8:52AM local time (1:52AM GMT). However, there were no immediate reports of casualties or damage.

People were trapped in destroyed towns with no food nor money. The rescuers struggled to find survivors in rubble of hundreds of collapsed buildings; and health ministry teams and Indonesian soldiers have arrived in Padang to aid the search for survivors.

In addition, the earthquake struck nearly 12 hours after a powerful quake in the South Pacific that triggered a devastating tsunami but experts said the two events were unrelated.

I felt a deep sense of pity after reading this news report. It reminded me about the Morakot Typhoon in southern Taiwan, August. The typhoon, just like the earthquake, has ruined thousands of people's houses and families. The typhoon has caused bridges and buildings to collapse, and a flood that whipped out an entire town. People were trapped, and the power lines were cut so that there was no way for the trapped victims to contact the outside.

However, these are the horrible things that we do not have the power to control. Like many other natural disasters that has caused certain changes in either environments, or humanities throughout the history.

'According to the Mayan prediction, the 21st of December, 2012, will be the end of the world.' This is the main theme of an up coming movie called 2012. It might seems quite foolish to worry about something that happens in a movie, but what if it is real? 2012 is not as far from now as we thought. In fact, it's only 3 years later!



In the movie, there are scenes of hundreds of aerolites shooting down from the sky, buildings collapsing, ocean drowning the land, and earth cracking...etc. However, according to the information from So The Maya's Were Right After All, the Mayans had never predicted anything specific about what will happen on the day. The thing that is known, is basically that on this day, the Sun will be posited on an unique spot. Which the Sun will sit precisely on the heavenly crossroads between the Milky Way and the galactic equinox, forming a perfrctly alignment with the center of the galaxy.

Personally, I think what happens on the day, in the movie, is quite unbelievable, and unrealistic because first of all, everything just happens so suddenly; and further on, I've been thinking that maybe things are already happening right now, instead of all happening at once on the day. The climates have been changing oddly, and there are more and more natural disasters been occurring such as Typhoon Morakot in Taiwan on the 7th of August, 2009. Also, Earth's magnetic field is in a constant state of change. And so the Earth might have been gradually devastated until the day of the 21st of December, 2012. Though, what will happen specifically is still an open question. In fact, I believe that to many people, it's still a question that rather the day is real or not.

Hoever, What should we do if it is true that the world ends on the 21th of December, 2012? Should we just lay back, doing nothing, and wait for this very day to come? Should we start running around, screaming, and panic? Or, with all those highly progressed technology, and those smart brains that we have in our world, it is possible for us to do something about it?

The movie The Last Samurai was about Nathan Algren (by Tom Cruise), an American captain who had gone to many wars; and unfortunately, these memories of wars have happened to be his tragic flaw. However, one day, he was ordered to go to Japan, and so, he started his 'hero's journey'...

The setting of the story was around 1878, when the Japanese Empire was modernizing. Nathan Algren was ordered to go to Japan to teach the Japanese how to use modern weapons such as guns and cannons; and also to teach them how to fight with those weapons in a war. At the time, Nathan was alcoholic, apathetic, and had just lost his job... so basically his life was miserable, and he had lost himself. In the 1st war, He led the modernized soldiers to fight with the samurais, who refused to be modernized. And then, in the end, the samurais won the war.

After the samurais' victory of the 1st 'Modernity v.s. Tradition' war, somehow the samurai didn't kill Nathan, instead, they took him back to their village. In the village, the they took care of Nathan. They provided him a place live, provided him food, and also cure his injuries...etc. At first, Nathan didn't quite understand the culture of the samurai. In fact, he even belittled it sometime. However, as time went by, he started to love the culture of the samurai. Which I think, it's because that he found himself in this kind of honorable way of life, which everyone were tough yet respectful.

Then, after a few months, the samurais brought Nathan back to Tokyo, for him to return to his army. Also, on n the other hand, they went to Tokyo for the 'leader' of the samurais to meet the emperor of Japan. However, unfortunately either of these went well. Nathan didn't return to his army, instead, he chose to help the samurais to defeat modernization; and for the 'leader' of the samurais to visit the emperor, and talked about the conflict between modernization and the traditional, the 'leader' of the samurais turned out to become a prisoner.

While the 'leader' of the samurais was in the prison, Nathan, along with some other samurais, went to rescue him; and one tragedy that happened in this movement, was that the son of the 'leader' died. 'Father, it is my time, please let me stay,' said the son. Then, just before he died, he pulled out his swords, ran to the soldiers, and wanted to kill them with his last breath. However, he got shot to death in the end. And then after the 'leader' of the samurais was rescued, the samurais, and Nathan, returned to the village. They began to prepare for the 2nd war against the modernity.

In the 2nd war between modernity and tradition, the modernized soldiers were no longer weak as they were in the 1st war. They have learned better skills of using the weapons, and were better trained for fighting in a war; yet, the samurais stayed the same... Therefore I believe that most of the people could predict how the 2nd war ended.

Yes indeed, the samurais lost the 2nd 'Modernity v.s. Tradition' war.

However, even though the samurais lost the war, I was impressed by their spirits. They were always proud of who they were, no matter how much things have changed, due to the modernizing. In the end of the movie, the 'leader' of the samurais asked Nathan to kill him. He told him that he was honored to die in a war. And then, when he died, all the soldiers bowed to the 'leader' of the samurais. In which, I believe it was because that they were touched by the spirit, and loyalty of the samurais, to their tradition... and most importantly, like I'd mentioned that they were always proud of who they are.

Newton's laws of motions, and frictions, are everywhere in our daily life. Let me give you an example:

Last Friday was HIS' field trip to Leofoo Village amusement park. Let's pick on Newton's 1st law of motions, 'an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force,' as an example: The first ride that Grace, my partner, and I went on was 'Volcano Adventure' (if u translate it from Chinese into English). How did Newton's 1st law of motions apply on the ride? Well it might be hart to see because everything was in controled by machines. However, the most obvious observation was that in the end of the ride, Grace leant foreward when the boat stopped; and the reason why was because that while the boat was stopped by the machine, there was no other force to stop Grace and mine motions of moving foreward.

Further, the ride on 'Volcano Adventure' was also an example for both kinetic friction, and static friction. When the static energy was greater than the kinetic energy, the speed of the boat slowed down. Which was what happened when the boat was stopping in the end of the ride. I think the machine had somehow increased the static friction between the track and the bottom of the boat, and then caused it to stop eventually. Also, in addition, I wonder if when the boat was sliding down from the ramps, its kinetic friction increases because when it slid down from the ramps, its speed increased. However, again, it's hard to prove this point from this case because everything was in controled by mashines. Hwo knows if they also controled the speed of the boats or not?

P.S. LeoFoo Village was FUNNN!! :D

The article, Geese decline 'caused by climate,' from BBC news, tells that the RSPB has warned that the decline in Hampshire's population of brent geese may be caused by climate change...

'To keep population levels stable, around 15% of a wintering flock should be young. This year, it's less than 1%,' said Chris Cockburn, the RSPB Langstone Harbour warden. These brent geese breed in one of the coldest place on earth, where it's extremely sensitive in any changes of its temperature. Therefore the climate change, which the general temperatures on earth are rising, has highly effected the breeding of the brent geese. They wouldn't be able to breed normally under such climate change.

In addition, I'd like to make a connection between what happened in this news article and what we've been learning in 09 humanities. We've been learning based on the topic 'why do civilizations collapse?' In which we've learned that one of the factors that causes a civilization to collapse is climate change. Therefore, as a result, in this case the climate change is causing the 'civilization' of the brent geese to decline.


P.S. The other possible reason for the decline of brent geese may also because that the Arctic foxes has taken the youngsters and the eggs.

1. Virus 'triggers child diabetes'

'Although genetics is known to play a fairly substantial role in a person's risk of developing diabetes, environmental factors must also be involved and the idea of a viral cause of diabetes has been considered for decades. '-- Virus 'triggers child diabetes', BBC News

On the SMASH Day of the 4th of March, our task to build a tallest possible tower out of clay and toothpicks. We were instructed to draw a sketch of the design for the tower of our own teams, before we started to build our towers. Which was quite an important part of the scientific method because it gave you an idea of what you shall do next before you move on. However, we usually neglected it because we usually thought that we already had an idea of what we shall do in our head; or perhaps, sometimes we just wanted to try and see what happens.

Personally, I think that drawing sketches may be important, but not quite useful. Our team failed on the task, even though we've drawn a sketch of the design for our tower before we started to built it. Therefore I think sometimes you should just try different things as you move on; well, at least that's what we (my team) did at the end. We changed our original tower design a bit so that it could be built taller without collapsing. The reason of why we changed our design was because that our tower seemed to fall apart when we tried to follow our original design. And so, although we failed the task, we've learned another problem solving skill, which is to think of another solution when the original one was not working. :D

‘What are they?’ asked Jaguar Paw’s wife. ‘They bring men,’ replied Jaguar Paw. ‘Should we go to them?’ she asked again. ‘We should go to the forest, to seek for a new beginning,’ he said. Then both of them, with their two sons, left the cost and went into the forest, and leaving the Spanish boats breathing on the coast.

‘I’m Jaguar Paw, son of the Flint Sky. My Father hunted this forest before me. My name is Jaguar Paw. I and a hunter. This is my forest. And my sons will hunt it with their sons after I am gone,’ Jaguar Paw thought, ‘this is my faith...’ Jaguar Paw and his family walked deeper and deeper into the forest. Day after day, they continued their seeking of a new place to settle down; a place to begin a new community.


To seek for a new beginning was definitely difficult. However, since Jaguar Paw was a hunter, he was very familiar with the forest. Therefore he and his family survived quite well in the forest. Jaguar Paw knew where to get all the water, food, and even herbs in the forest. He also knew the easiest path to pass through the woods in the forest, where they shall travel on during days; and he knew the safest place in the forest, where they shall stay during nights.

Sometimes, when Jaguar Paw when out to hunt, his wife would stay at a safe place, and take care of their sons. One day, while Jaguar Paw went out to hunt, his wife and sons stayed in a cave and wait for him to return. BOOM! Suddenly, a gun was fired somewhere in the forest and made a massive thunder. Jaguar Paw’s wife was shocked, and so were their sons. But she stayed calm and quickly covered her sons’ mouths. ‘Shh..’ she looked into her sons’ eyes, telling them to be quiet. And then she saw something was moving behind the bushes, near the cave. ‘Jaguar Paw?’ she thought. But, just right before she decided to walk over and check things out, a jaguar, using his last breath, stretched his paw and roared…

‘Honey!’ Whispered Jaguar Paw, behind the bushes of the other side. Jaguar Paw’s wife quickly recognized the voice, and as well as where it came from. She looked at the place where the voice came from, and saw him putting a finger in front of his mouth, signifying her and their sons to be quiet. Then he pointed to the top of a tree, signifying them to climb up there. And they did so. Jaguar Paw’s wife carefully carried their little son on her back, and supporting their older son (who was already able to climb the tree on his own) while climbing the tree.

‘Ah… Mama!’ the older son cried soundlessly. But it was too late, he slipped from the tree and… A hand grabbed him just in time! It’s not his mama’s hand, instead, it’s a stranger’s hand. A hand of a unknown young man. This man looked terrified. He was also hiding from something, or someone. And so were his fellows, who were sitting right next to him, on the top of the tree. One of his fellows held Jaguar Paw’s wife and genteelly pulled her up. ‘Thank you,’ she said, scared but still very calm. ‘There’s no need to be scared,’
said the young man, who had just saved Jaguar Paw’s older son, ‘I belief that we are all here for the same purpose. We are all seeking for a new beginning of life.’


‘I’m Jaguar Paw, son of the Flint Sky. My Father hunted this forest before me. My name is Jaguar Paw. I and a hunter. This is my forest. And my sons will hunt it with their sons after I am gone,’ Jaguar Paw said, solemnly, standing on the highest branch of the tree, ‘I shall only share the forest with my sons.’ ‘Our home has been destroyed and overthrown by outsiders. We’d be willing to become your sons and daughters, just to find another home and a new life,’ said the young man. ‘Very well, I shall share this forest with you. And we shall all seek for a new home and a new life together, in this forest, our forest. My sons and daughters…’

According to the BBC news, Rain and snow bring relief to northern China’s severe drought by Matt Taylor, from the 22nd of Feb. 2009, I've noticed that the fact of climate change in the world is not only because of the Global Warming. It may also be effected by some artificial impacts as well.

'Last week’s snow and rainfall is being partly attributed to the recent cloud-seeding, which has been the government’s response to the drought situation. Cloud-seeding is a method of artificially enhancing precipitation by firing rain-producing molecules into clouds.'-- Rain and snow bring relief to northern China’s severe drought by Matt Taylor, BBC Weather

The wet season in China usually occurs in between May and September, and the weather is often very dry in the winter. However, the Chinese government used this method, the cloud-seeing, to create precipitation, in order to help alleviating the drought in northern China. But, nevertheless, even though the cloud-seeing has successfully alleviated the drought, isn't it going to harm the environment on another aspect? I'm pretty sure that it will, somehow. Yet, it's only a thought of mine. :]

'No animal shall drink alcohol,' but there were two words that had forgotten. Actually the Commandment read: 'No animal shall dink alcohol to excess.' -- Animal Farm.

Napoleon and other pigs came upon a case of whisky in the caller of the farmhouse. After drinking, Napoleon became so ill that he though that he was dying. And so he animals started to worry about what should they do if their Leader were taken away from them. Also, meanwhile, rumors about Snowball has introduced poison into Napoleon's food, went around within the animals. Then finally, as his last act upon earth, Napoleon had pronounced a solemn decree that drink of alcohol was to be punished by death. But, Napoleon did not die, eventually, and he changed the commandment so that he wouldn't have to die. Hahahaha..(?)

As we all knew that the four factors, which are geography, society, economy, and technology, cause a civilization to rise. Therefore, by looking at a several of ancient civilizations, you may notice that for most of them, had similar geographies (such as rivers), social organizations (such as class systems), economy (such as trading), and technological skills (such as irrigation). However, in this article, it will be focusing on one of the four factors, technology.

I picked the technology of Egyptian Civilization to compare the technology of the Mayan Civilization. Both of these civilizations had developed their own counting systems/math skills. Even though these counting systems/math skills were different, both Mayan and Egyptian Civilization were able to use these skills to measure, to build. Therefore, they had both developed their building skills of their typical architectures. In which I'd like to mention that they had similar-looking pyramids; and these pyramids were used for a similar purpose as well --- in both civilizations, the leaders were buried under the pyramids. But, there were also some differences between the pyramids of the two civilizations. In the Egyptian Civilization, a pyramid might was simply a memorial of a Pharaoh. But a pyramid in the Mayan Civilization, it could be used as a calendar, a temple, or the place where ceremonies were hold.

Besides the development of math and architectures, city planning was also one of the main technological developments of a civilization. The Mayan Civilization, was well organized into city states, unlike the Egyptian Civilization, the Mayan Civilization was not a unified civilization. And so, obviously, the two civilizations would had different kinds of governments. Unlike the Egyptian Civilization, which only had one king at a time, the Pharaoh, the Mayan Civilization had different rulers being in charge of each city states in a time.

As a result, technologies of some ancient civilizations could be quite similar to each other, yet different from each other as well. Differences showed us the typical characteristics of each civilizations, and the similarities surprised us because it made us wonder how was it possible.

We all live in the yellow submarine, yellow submarine, yellow submarine...

During last Tuesday's SMASH day, our mission was to build a periscope to see what's inside a box, which was placed on the table, from under the table. The materials for building the periscope were papers, card boards, scissors, tapes, and 4 mirrors.

Personally, I think this was the hardest SMASH day mission so far! Even though we've tried and kept on trying, for 1 hour. We kept changing the design of our periscope, and experimenting to see if it worked. But eventually, we still failed the mission. Oh, well, actually we semi-failed the mission because we could see inside the box, it's just that we couldn't recognize what the things were. I wonder if it was because the mirrors in our periscope were placed in a wrong way so they weren't reflecting effectively. :[

'A Japanese spacecraft is due to launch on a mission to help scientists understand and monitor how the Earth's climate is changing' - Climate satellite set for launch, BBC News.

I belief that fpr most of the people who lives on Earth, has noticed about the seriousness of global warming. In which the Earth's climates change unusually throughout years, and for most of the cases, the temperature on Earth rises.

In the article Climate satellite set for launch, it is basically talking about a Japanese spacecraft, Gosat, is to identify and monitor sources of CO2, to support compliance with international treaties and agreements. Gosat will measure 2 different greenhouse gases, CO2 and CH4, by 2 sensors. These sensors that Gosat will be using in order to measure the greenhouse gases are the Fourier Transform Spectrometer (FTS), and the Cloud and Aerosol Image (CAI). The purpose of measuring the greenhouses gases, is that it can help scientists to understand and monitor how the Earth's climate is changing. Which is one of the major global issues on Earth.

Gosat is set to blast off between 0354 and 0416 GMT on Friday from Tanageshima.

I'm glad to see that people are trying to figure out ways to solve global warming. I think understanding how the climate has been changing is definitely important because this way, people will know what exactly the problem is, and then it'll become easier to solve, or at least reduce global warming.

'The headline Retail Prices Index (RPI) measure fell to 0.9% from November's 3% rate, the biggest fall in 28 years.' - BBC Business.

One of the major issues in now-days' current event is that the economy of the entire world is collapsing. In the post Big fall in UK inflation to 3.1% , from the BBC Business News, it's basically talking about how serious the falling of UK inflation is today. In fact, not only how serious of a problem it is to the UK. Although such issue, the falling of inflation, is actually happening in every other countries on Earth.

In order to reduce the rate of inflation, there are discounts being displayed, especially during the days before Christmas. This reminds me about Taiwan, in which shops also do a lot of sales so that people will actually buy something during this horrible situation, when the world's economy is collapsing, many unemployed people, and poor people. However, doing sales is only one of the solutions for reducing the falling of inflation.

I have to be hones that there are a lot of things in this article that I don't understand. Such as some of the representing rates. However, I don't think there is any biases in this article because it's basically just telling how's the UK doing with the big fall of inflation effecting it.

1.How do Paiwan people show their respect to the animal they hunted?
Paiwan people show their respect to the animals that they hunted by wearing their tusks, teeth and even feather on their head.

2.Why archery is so important to Bunun people? How did fathers train their children to be an archer?
Archery is important to Bunun people because hunting is a part of their life. Fathers train their children to be an archer by teaching them shooting skills with deer ears -- before the 1st hunt, children practice their shooting and aiming skills on deer ears.

3.Why are bats welcomed by Ancient Chinese culture? But in western societies, why do people regard bats as nuisance?
Bats are welcomed by Ancient Chinese culture because they belief that bats can trace away evil spirits. However, western societies regard bats as nuisance because they are considered disgusting and dirty.

4.This video shows a lot of living extinct animals in Taiwan. Please choose one animal that impressed you the most and describe its habitat and its way to survive in the natural environment?
The frog that lives in a bamboo impressed me the most. I'm impressed by its habitual behavior. Which is that every male frog has their own bamboo; after mating, the female frog will lay her eggs in the male frog's bamboo and leave the bamboo; and then the male frog will protect the eggs until they become tadpoles, then he leaves the bamboo; then, the female frog comes back to the same bamboo (it's amazing that she's able to do this) in about once a week, feeding her babies (tadpoles).

During today's SMASH day, we did an activity which each group had to get their marbles, passing point-stickies, and into a cup at the end. There are point-stickies of 10 and 15 points, placing randomly on the table. During the activity, we could use anything to block, bounce, or lead the marble to the point-stickies. However, in one condition, we have 2 chances but could only flick the marble twice in each role -- flicking only.

I was a critical thinker and an effective communicator while participating the activity. It's because that first of all, we had to think of a way to get the marble passing as many point-stickies and get as many points as possible; and secondly, we were working in groups, in which communicating was a really important skill for us to succeed the task. For some specific example of how I showed that I was a critical thinker and an effective communicator is that I've been thinking how the marble would bounce if I put the plastic cardboard in a certain position, and then I discussed with my group mates about my ideas, then finally we tried if it worked together.
