Stone Mountain and Atlanta (1)

I've travelled to Stone Mountain in Georgia in the US for the conference. It was a short trip for about a week, but meaningful to me in that it was the first visit to the US and the first talk in a conference. Talking about the conference tends to be boring to readers and myself. So, I'm gonna make it brief.

The conference took place at Evergreen Marriott Conference Resort. I stayed in the conference hotel for the first two nights and had to move out to the other hotel due to the expensive hotel rate. I was quite nervous in the first day of the conference since I was supposed to give a presentation. To make things worse, my condition was terrible on the first day probably because of food. (I really really hate continental breakfast)

Majority audience were lecturers and professors. My presentation was uncontentious, and the Q&A was quite easy. I find that presentation is always easy, but Q&A is not easy. Q&A is more difficult to execute well, and I want to be good at it. Most people came to the conference as a group, and some people individually came. During the session in which I was, I was able to meet several famous scholars. They are equivalent to Lady Gaga to the students studying the same subject. The invited speaker gave a presentation for his latest research, followed by three presentations for the conference papers.  
 
It was great to meet people, particularly PhD students from other Universities in the US. I've never met such many american people and it was great to talk with american students. I got extremely inspired and motivated during the banquet. It is a great opportunity to look at myself, and I realized that I had been meaninglessly spending such a precious time in the UK. This introspection might be the biggest gain from the conference.

 From the third day in the conference, I stayed in the other hotel, located several miles away fron the conference resort. I had to take taxi whenever I move around because there is no public transportation other than taxi. I went hiking to Stone Mountain. Readers can get information from a number of website for Stone Mountain. At the beginning, I imagined a hill, but when I reached the peak of Stone Mountain, I realized that it was a kind of mountain. My T-shirt and my face were completely wet by sweat during hiking and the weather was warm enough to remind me that I was in the South US. The scenery of the town was not very special, but very peaceful probably because of the lake.

After spending half an hour in the peak of the mountain, I felt like to go to the park located in front of the memorial carving depicting three confederate leaders of the Civil War. On the way down, I met two women, on their way up to the mountain, asking me how much they have to walk to get to the peak. I was thinking something which I don't remember now, and it felt like I was at the peak just 5 minutes ago, so I said 5 minutes. They said "Thank you". After they had gone, I realized that it was way more than 5 minutes. I appologize if one of you are reading this now!

Walking around the town Stone Mountain was quite enjoyable. This is probably because I had been busy since I started my study in Oxford. On the day, I was chased by nothing. I've already booked in a hotel in Stone Mountain, so even if I rush looking around the town, there was nothing else I could do in the town after that. This is maybe the reason why I remember the people I saw on the day and my image for the town is so clear.

In the park, unlike my expectation, just a few people were enjoying the sunny day with the memorial carving. I could see American people's effort to commercially exploit their treasure. But unfortunately, they were some construction and refurbishment. At around 5pm I took a taxi, and came back to my hotel.

Miss Saigon and technical perfection - Yuna Kim (3)

Yuna's rehersal for gala. "Only Hope"

When we talk about Yuna, her 2nd senior season is evaluated not splendid as much as other seasons. Nevertheless, I cannot and won't forget both Die Fledermaus and Miss Saigon, because of the special connection with me. From this season, I started watching Yuna's performances in Grand Prix. Technically, she became world champion in 2009, but her skating skill reached the perfection in this season. Since I don't remember all the scores, I am going to make reference to Wikipedia.

'Kim started off the 2007-2008 season winning the 2007 Cup of China with a total score of 180.68 points, which was 24.34 ahead of silver medalist Caroline Zhang.'
'At the 2007 Cup of Russia, Kim won both the short programme scoring 63.50 points and the free skate with 133.70 points, to finish first overall with 197.20 points, 24.43 ahead of silver medalist Yukari Nakano, which set a world record for the free skate score under the ISU Judging System.'

The author watched both Grand Prix competitions, and stongly felt that Yuna's skating skill was upgraded. First of all, she looked comfortable in senior competition and technically stronger than the previous season, probably because other problems such as skating boots and her back injury had been sorted out. The author strongly felt that she was going to be unbeatable in the season, and she successfully accomplished defending her champion in Grand Prix Final.

Comparing 'Die Fledermaus' with Yuna's other short programs, I would say 'Die Fledermaus' is quite unique. She was able to make impressive debut due to the strong character in the short programme 'El Tango de Roxanne'. In the following season, 'Die Fledermaus' was a trial to show her different view. In fact, I really liked this programme. She was so cute and adorable... but the programme failed to present her high score. Since then, Yuna has tended to stick to the music with strong beat like 'Danse Macabre' and 'James Bond Medley', and this is why I take 'Die Fledermaus as a unique programme for Yuna.

'Miss Saigon' is not my favorite long programme. But she was extremely strong during Grand Prix in China and Russia with this programme. Particularly in Russia, she made it flawless for the first time in her senior competition, setting new world record. I was one of the people who were expecting Yuna to set new world record breaking 200 point at World Championship in Sweden.

Back then, I was working in a company in the UK, and when I got to know that World Championship was going to take place in Sweden, I seriously considered travelling to Sweden to watch Yuna's skating. In 2007 to 2008, I had time and money. So I did it. Spending the whole vacation with World Championship in any sports even was one of those things I used to dream about, so I booked all the events: singles (men and women), pair skating and ice dancing. If you are a big fan of Yuna and have read carefully this story so far, some of you may be able to guess the dramatic point of the story. Yes, it is Yuna's injury right before the Championship. Before she got injured, I already made all the reservations for hotel, flight and World Championship. One month before the competition, her manager has announced that they have to see the state of recovery to decide her participation.

In fact, back then I was fascinated by figure skating itself, so Yuna's injury was a disappointing news rather than the end of the world. With said that, having a world-class skater like Yuna who you can support during the competition was the most important reason for my travel plan, so I had to keep my eyes and ears on the news about her recovery. In the end, she decided to participate the competition, but most people would have thought that the circumstance will be different in the Championship because Yuna had been off the ice for a couple of weeks.

In March 2008, the World Figure Skating Championships was held by Gothenburg in Sweden. I had to spend most of time in Scandinavium, the venue of the competition, because the weather was quite cold. When I arrived in Scandinavium, pair skaters were practicing on the ice. I clearly remember this because of Aliona and Robin. 'Gorgeous, Graceful, Artistic ...' this was my first mipression.
Watching World Figure Skating Championship was amazing. In particular, I was blown away by men singles. In 2008, there were several competitors for gold medal, making it hard to predict who's gonna win the competition. When the last group was introduced by the announcer, the fever in Scandinavium was just like a concert hall. Just to remind you who were in the competition, there were Jeffrey Buttle, Brian Joubert, Johnny Weir, Daisuke Takahashi, Stephane Lambiel and Patrick Chan. Though Jeffrey won gold medal, my favorite was Daisuke due to his sensational short programme, hip hop version 'Swan Lake'. The choreography was brilliant, but he's got short and speedy style of skating skills nobody could easily copy. I personally think 2008 was one of his best seasons though he ended up with no dedal in World Championship. I actually supported Daisuke in the Vancouver 2010 Winter Olympics.

Men singles was the highlight not just because of the Japanese hit hop dancer but the diversity of world-class skaters. The two Russian giants swept the world from late 1990s to early 2000s. Since Evgeni Plushenko left the ice, there has been no king in mens single. My favorite is Alexei Yagudin, and he is the only one who can present me both technical perfection and artistic impression in mens skating. Since Michael Jordan left a basketball court, a number of fans left courts with him. But the situation was different in mens single skating. Several great skaters could not shine under the giants, but they had been wating with great talents. Jeffrey, Brian, Johnny, Daisuke and Stephane. Watching these skaters' performances was literally fantastic. You can easily tell the different styles of each skater. A good analogy would be tasting five chocolates with five different flavours. When it comes to men singles, it was definitely better than Vancouver Olympics.

I quite liked pairs event. All the techniques were magnificent. And it seemed like advantageous than singles in that they've got their partner to play with. Watching pair event was quite similar with watching music videos. There is a story, a partner and a music. Ice dancing was a bit boring maybe because I have no ability to tell the difference between good and bad performances. But Tessa Virtue and Scott Moir looked nice. (They are a real couple, aren't they?)

Lastly, female singles. After all, Yuna failed to win the competition. However, this experience was so precious and important to her. Injury can happen to any sports event and any player. And gaining know-how to avoid injury is extremely important. I think Yuna learned this through World Championship in 2008, and she hasn't made the same mistake again. Probably it was the most valuable bronze medal in her skating career.

Since watching 2008 World Championship in Gothenburg, I became a big fan of figure skating. I really enjoyed individual skater's show and their competition. When it comes to football and baseball, I personally prefer watching it in a pub with a pint of beer. But figure skating is worth travelling to the place, watching the performance and feeling the atmosphere.

Lang Lang visits the Oxford Union

Friday is always somewhat difficult to focus on working. Particularly, on 17th February, a Chinese pianist Lang Lang was supposed to visit the Oxford Union, so I left my office at 4pm with no hesitation. I had no information for Lang Lang other than his performance at the opening ceremony of Beijing Olympics. But the rumor had it that he will play some pieces of classic music in the debating chamber, so I was excited about watching one of the best pianists and the performance. That's probably all graduates want to do on Friday.

He spent one and a half hour in the chamber. His performance was impressive as everyone would have expected, but his life story was also quite interesting. Even though I have quite many chinese friends in Oxford, I haven't seriously thought about China's 'One child policy' before. But Lang Lang's story in his early years allowed me to taste what the policy have been like in China.

In Asian culture, a child is a hope as well as a present. We are quite familar with the stories of a number of artists and sports stars encouraged (occasionally forced) to practice harder by their parents. As I have introduced previously, a Korean figure skater Yuna Kim is well known for her enthusiastic mother as well as her skating skill. I have neither negative nor positive opinion on those types of parents. To be honest, if I happen to find a great potential and talent from my kids in the future, I might do the same thing. It might be one of the most important parent's responsibilities to discover the kid's talent and encourage it. Children have right to be treated as independent human beings, and yet we also have to admit that their lack of experience, and this is where the parent's role comes in. According to me, the two most important responsibilities of parents are giving love under no condition, and discover, encourage their talents.

No one can earn everything losing nothing. Trade-off has to be remembered. To climb to the peak where no one can easily reach, you must give up something anyone can easily gain and experience. The important thing is there should be 'no regret' when you retrospect your past life.

Photon (Nano Story - 1)

'Don't tell me sky's the limit when there are footprints on the moon'

I've come across this from the TV show 'The Apprentice' on BBC.  The one who came up with this for the first time might have thought this is brilliant, but it feels like it rather tends to clarify the limit which is Neil Armstrong's footprints on the moon. For this reason, I prefer 'Sky is the limit' as sky also means Universe in a larger context.

In the last year, I've experienced multidisciplinary nature of nanotechnology in the lecture theatres and laboratories at Cambridge. Nanotechnology incorporates physics, chemistry, mechanical engineering, material science and bioscience. My background is mechanical engineering and there was another student who had the same background with me in the master's programme. She and I both had to admit that nanotechnology is way more interesting than mechanical engineering. There is nothing wrong with mechanical engineering, but simply nanotechnology was amazing and mind-blowing.

A number of scientists across the world are carrying on diverse projects associated with nanotechnology, and the outcome is normally published in journal articles. However, the public (here, I define the public as non-scientiests) cannot readily access those scientific papers, so this is where the scientific news articles come in. Yet I still occasionally find that scientific news articles often fail to deliver scientific information to the public because they are always missing the introduction part of the story. Among method is to use analogy to introduce the concept and the impact of technology, but it tends to rather exeggerate the original story. This motivates me to introduce novel technologies focusing on the fundamental nanotechnologies where the new devices and techniques are based on. Any one who happens to read my scientific blog, and find any part incorrect or controversial, please do not hesitate to make comments. Criticism is always welcome!

"Tripping the light fantastic"  (Original Article)

I am going to begin this story with throwing one of the most significant questions to physicians, 'What is light?' Light is definitely sort of a wave. But could you believe that light also consists of particles called 'photons'? Fundamentally speaking, Li-fi is based on photons. In fact, light emitting diode and laser diode also exploit manipulating photons.

As most would know, 'photo' has a meaning 'photograph' as well as 'light'. Then how about 'photon'? In quantum mechanics, all the particles are treated as waves as well as particles, and this is called 'Wave-particle duality'. To help your understanding, we better get started with 'Double-slit experiment with electron'.

Double-slit experiment (from Wikipedia)

The above figure shows the principle of double slit experiment. A plane wave of light illuminates the screen with two slits, and the waves interfere each other after passing through the slits. In terms of interference, the light can be regarded as a wave, but the illuminated light on the screen is also observed groups of particles.



Inteference pattern on the screen (from Wikipedia)

This figure illustrates that the intensity of absorbed particles on the screen increases over time. From this aspect, the light behaves as particles do. However, the figure also shows the similar pattern which is normally observed from wave interference. As I remember from the lecture 'Physics at the nanometre-scale' at Cambridge, we still get this interference pattern even if you shoot a single electron to the screen including two slits. Therefore, the fact of the matter is that, nobody knows whether electron is particle or wave. With said that, a number of physical experiments are well explained when we regard them as waves.

The wave-particle duality of electron is a good example to introduce photon since it corresponds to the particle of light wave. Thus, the light generated from LED is a series of photons. Whe it comes to the technology of those devices, the key issue is how to manipulate every single photon. To improve the efficiency of light generation, a specific semiconductor is chosen and engineered for the specific purpose. And in semiconductor industry, one of the key technologies is confining electron and hole in a extremely small area, and hence doping in nanometre scale is required. Accordingly, several fabrication techniques to deposit dopants in such small area have been developed. Equally importantly, characterization techniques also became extremely important, and hence gradually have been developed. To observe and evaluate the heterostructure in nanoscale, electron and atomic force microscopy are preferentially used in industry and research institutes. I believe there willl be more chances in the future to talk about characterization techniques and why those structures cannot be observed through optical microscope.

The Lark Ascending and Yuna - Yuna Kim (2)

The lark ascending was 'art' rather than 'sport'

Her first season as a senior skater was in 2006 right after the gold medal from world junior championship. In short, I would say her performance was incomplete version due to her injury, but the short programme 'El Tango de Roxanne' and the long programme 'The Lark Ascending' were great enough to become the legends. A number of her loyal fans including the author particularly love these two programmes since she was just a girl rather than the queen.

'El Tango de Roxanne' showed that a music with strong and fast beat so well fit together with her skating style and techniques. She broke world record by scoring 71.95, and this definitely showed the world what they were about to see from Yuna for the next several years. Her performance in short programme in world championship is famous for high score and her debut performance in world championship, and yet many South Koreans' favourite might be 'The Lark Ascending'.

People agree that Yuna's 'The Lark Ascending' has something special. For me, I think it's special because her jumps, spins, step sequences and spirals do not look like the compulsory elements in the programme but a part of her choreography. Watching other figure skaters' skating, you get to count how many jumps they have done during performance. But in 'The Lark Ascending', all the technical elements are so beautifully integrated with the whole choreography, so the whole programme runs extremely smoothly. Of course, 'The Lark Ascending' is the masterpiece of Yuna's choreographer David Wilson. With that said, no skater other than Yuna can execute the choreography in such a beautiful way. When Yuna reached the level of perfection with 'Danse Macabre' or 'James Bond Medley', I used to think that Yuna's 'The Lark Ascending' was possible because she was a young girl back then. But when Yuna came back with 'Homage to Korea' in 2011 World Championship, her choreography in Arirang seemed to be another version of 'The Lark Ascending'. Yuna's got long arms and legs, which would be a great advantage for expressing a music with slow tempo. On top of that, Yuna is simply a good dancer. She knows how to dance with a music with slow tempo as well as fast and slow beat.

I hope Yuna include 'The Lark Ascending' in her ice show someday. She's got so-called legendary programmes such as 'Danse Macabre' and 'Concerto in F', which will resound for a long time as a classic skating programme. Yuna hasn't done clean programme and broken world record with 'The Lark Ascending', but it will remain forever as one of the best programmes in figure skating history to her fan and to me.

World Junior Champion - Yuna Kim (1)



Yuna won 2005-2006 World Junior Championships

January 2012 is a quite brutal season so far. It's the second term of the first year, and now I serious feel the rapidly growing pressure that the specific goal of my PhD must be decided and the first outcome must be created in a couple of months of time. So, recently there has been no fun since I came back from skiing trip, and there will be no exceiting thing for a while. My life has been occasionally boring like this and probably will be like this from time to time during my PhD study. Yet this blog should be stayed alive. So, I decided to talk about the number one celebrity in South Korea for the last five years, Yuna Kim.

In this world, there are two types of prodigies. Some prodigies shine bright in their early ages, but the great expectation is not continued, and the name is soon forgotten among the public. The other type grows up with  their great talents. The representative super star of the latter case is Yuna Kim. The history of figure skating in South Korea is distinguished by before and after the appearance of Yuna Kim. She is such a super hero!

The weather in South Korea is cold enough in winter to present good background for winter sports such as skiing and skating. For a last decade, South Korea has been quite good in winter olympics due to one specific event, short track. In 2010 Vancouver Winter Olympics, South Korea was able to sweep gold medals from speed skating and figure skating as well as short track probably thanks to the ambitious project for 2018 winter olympic campaign which was confirmed to be Pyeongchang in South Korea by IOC committee. In fact, ice sports are relatively not restricted by weather condition, so those countries under an equatorial climate still have an opportunity if massive investment could be followed. But when it comes to snow sports, climate and topographic conditions are extremely important, so european countries have significant advantages. In South Korea, the amount of rainfall in winter is extremely small, so skiing resorts have to rely on artificial snow. After having skiing trip to Chamonix, the author felt that european countries are almost unbeatable in snow sports.

For South Koreans, 2010 Vancouver Winter Olympic was the most dramatic because two miraculous events happend. One was Mo Taebum's the first gold medal in speed skating followed by Lee Sanghwa's another gold medal. Both won gold medals from the shortest track event 500m, which means the fastest man and woman on the ice were all South Korean. The second miracle was Yuna Kim's perfect gold medal. She broke the world record in both short and long programme, accordingly the total as well. This story will be followed later in detail.

A frontier always deserves compliment. South Korea had never received attention in the field of figure skating, and now there are hundreds and thousands times of young figure skaters in South Korea who want to follow Yuna Kim's beanten track. But, Yuna's life story tells us how difficult it is to blaze a new trail.

I got to know her for the first time when she won silver medal in world junior championship in 2004-2005. Back then I though she was one of those prodigies who might be easily forgotten but I also felt she was having something speciall in her personality and appearance (she's got just adorable style). So I immediately knew she was going to be a star (of course didn't expect a super star like now). Figure skating has been known as the flower of winter olympics. The author still remember the rivary relationship between Michelle Kwan and Tara Linpinski because it has been introduced by several TV programmes in South Korea, even though there had been no Korean figure skater in world class level. So, when Yuna Kim won silver medal in 2005-2006 and eventually gold medal from world junior championship in 2006-2007, she was a present to South Koreans but also there was a question mark whether she would be able to overcome the gap between junior level and senior level.

Chamonix Mont Blanc (2nd and 3rd)

I woke up every three hour, and everytime I looked out the window. I couldn't see mountains clearly until half past seven in the morning. The mountains viewed through the window was literally magnificent and could be compared with one of the highest mountains in South korea.



The mountain view from the hotel room

After having one of the worst breakfast at 14 euro in the hotel, we rent a ski and a snowboard. It's been two years since I went to a ski resort. Ski boots were quite heavier than I remembered. On the second day, we were planning to go to Balme because of skier-friendly(?) slopes. There are diverse slopes including beginner and intermediate levels in Balme according to the guide map. Skiing is obviously a dangerous sports (some people may not agree with this), so we wanted to try easy one on the first day. Additionally, we watched a video clip on youtube someone took while skiing in Balme, and the scenery of the slopes was pretty amazing. Yet we didn't know how far Balme was located from the hotel. Actually the ski resort Balme was located far away from the town, so we had to take the coach for about 50 minutes. When we arrived at Balme, it was already 12 o'clock, so we rushed to the lift after purchasing lift passes. The lift pass covers most of the best ski resorts in Chamonix and tour programmes for three days at 104 euro. The slopes viewed from the lift on the way to the peak were quite steep more than we thought. When we reached the top of the mountain, two of us were extremely pleased due to the panorama and the fact that we are in Alps. Believing that I'm experienced traveller, I strongly suggested that we should take pictures right now since the weather was not terrible yet. According to weather forecasts, there was going to rain soon. But Mr Chun looked extremely motivated to snowboard, so we took just a few pictures at the peak of Balme. These photos are only memorable photos from the first day because of what happened in ten minutes.

On the way to the ticket office



Chamonix covered with clouds. It was raining in the town and snowing in the mountain. This often happens in Chamonix, so the official Chamonix website provides the anticipated altitude at which rain transform into snow for skiiers



Lost!! Let me see my map~



Balme. It was relatively good except the location and the weather.

Originally, we were planning to take the longest and most gentle slope at the beginning. When we watched youtube, the slope had a potential issue for Mr Chun due to the narrow. Particularly, I realized that a narrow and gentle slope could be the hardest course for the snowboarders in intermediate level. When he got in the slope, both of us immediately realized that it could be serious. So, I let him go to the other slope and he let me go alone. That was around 12:30 pm, and we couldn't see each other until 5:00 pm.
For over four hours, I had to ski alone. I don't usually mind skiing alone, but on the day, the weather was extrmely foggy and my ski skill was on the way coming back. Particularly turning didn't work well, so I had to slide down the slope not via ski blades but my whole body. The first day ski was quite painful. It was a big mistake to go to the peak straightaway. Whenever trying to turn particularly into right, I failed to shift my weight from the left to the right. It takes time to recover the sense and skill, and the first skiing experience after two years gap was not very enjoyable.

The third day in Chamonix and the second day of skiing was the highlight of the holiday. The weather forecast had been assuring that the weather was going to be fantastic (sunny), so we just crossed our fingers. Since yesterday was quite foggy and skiing was pretty much struggling, I desperately wished the weather would be nice.
We were planning to go to Brevent-Flegere. This resort covers quite large area in mountains, being located right in front of the Chamonix village. So, it took only 5 minutes from the hotel to the resort. Since we rushed to the resort from 7am, we were able to get ready to go by 9am. In contrast to the weather forecast, it was quite foggy again in the morning. But, the cloud was lightly touching the mountains, and the state of clouds felt different from that of yesterday. Hoping the cloud and fog disappear in a few hours, we decided to spend the entire morning at the slope for beginners.
Meanwhile, I was slowly recovering the skill in the morning. I realized that yesterday my entire weight was not properly shifted from the right to the left when I tried to turn right. This was sorted out by moving my body weight downward, which in turn effectively delivers my weight to my foot. Between 11.30 and 12.00, we saw a miracle. All the clouds suddenly disappeared, and we were able to see blue sky at 12.00.
Skiing at Brevent was one of the best things I've ever done in my life. The only one factor of the resort, the location, is good enough to be one of the best ski resorts in the world. People were enjoying skiing appreciating the panorama Alps mountains including Mont Blanc are presenting. The level of the slopes Planpraz was for us just enough to ski, and the quality of snow was extremely helpful to control the direction and speed. Originally we were planning to cross two different mountains and resorts via lifts: Planpraz and Flegere. But it seemed that the lift connecting two different area was off so we had to just hang around in Planpraz. Besides, there was not enough time to go through all the slopes for a couple of hours in the afternoon. If you ski in Brevent-Flegere, you cannot just keep moving forward because the slope is extremely beautiful, which makes you want to come back to the area. Here are some pictures from Brevent ski resort.

Taking a lift was a bit nerve-racking.

OMG she's got a nice style!

Chamonix Mont Blanc (1st day)

I've been to Chamonix Mont Blanc from 21st to 24th December. Skiing in Chamonix has been one of my dreams since I went to Chamonix in December 2007. Back then, I've tried skiing for the first time in my life, and it was fantastic experience! Since then, I've tried to learn skiing whenever there was a chance, and now I can say my skiing skill is intermediate level. Unfortunately I couldn't make it in last winter due to tons of coursework to do during the Christmas vacation. In this year, my resolution was solid. Fortunately, I found another 1st DPhil student in Oxford, Mr Chun. His skiing level seemed to be more or less on a par with mine, and he looked overexcited about skiing in Alps like me. Can't ask for any better travel mate than Mr. Chun.

Normally, if I have a long vacation like Christmas vacation in the UK, I prefer doing something at the beginning of the holiday. This is because most people are excited about no work for the first couple of days. So, I normally prefer doing something at the beginning of the vacation, and then come back to work during the holiday. That's why I'm writing this on the 31st December in the office.
On 21st December, we met in front of my house at 7 o'clock in the morning. Chun slept in his office again, and yet looked energetic as usuall. We had to depart early in the morning since it's actually quite a long journey (Oxford rail station - Paddington rail station in London - Liverpool street rail station - Stansted international airport - Geneva international airport - Chamonix) and we prefer spending a couple of hours in stations rather than missing bus, train, airplane and etc, messing up the whole journey. It was one of normal travel except a couple of things. Firstly, Standsted airport was terrible, and I will never use it again. They offered slightly lower flight fees than other airports, but the security people are extremely strict and rude. This was only terrible thing in this trip.

I had been worrying about the weather in Geneva and Chamonix. Several weather forecasts have said that there will be raining on 22nd. Flying over Alps on the way to Geneva is one of the key points in this trip, but unfortunately we weren't able to see anything other than clouds. When we arrived in Geneva, it was raining. If I had a chance to talk with the locals in Geneva, I wanted to ask if it's raining in December because of global warming or if this has been usual. But my concern was relieved as we approached to Chamonix. Drops of water were gradually changing to snowflakes. And when we got there, it was a small village painted with white pigment.

Probably right in front of the rail station

It would not be just romantic for the locals

We rushed to ski rental shops to rent ski jeckets and pants. I've prepared maps with the locations of ten ski rental shops. But when we walked down the street from the rail station for 5 minutes, I immediately realized that I wasted my time. Ski rental shops were everywere, and it's more proper to say that it's even difficult not to see a ski rental shop. We were able to easily rent two black jackets and pants. In the hotel 'Hotel Prieure', we stayed for three days and were supposed to rent a ski and a snowboard. It's 109 euros a night for a twin room excluding breakfast. The room was quite warm and quiet, and had a nice view through the window. Particularly if you arrive in Chamonix after 6 o'clock, and wake up in the morning on the next day, the panorama of magnificent alps displayed through the window is overwhelming. 

 As soon as we put down our stuffs in the room, we went out to have a dinner. I was thinking of two french local foods before coming to Chamonix: Fondue and Escargot, and tried Fondue on the first day. The price was reasonable (about 10 euros each), but there was nothing other than baguette and a pot of boiling cheese. When we saw what we've got on the table, we thought, 'This can't be a dinner'. But after finishing the baguette and a pot of cheese, we got quite full. This is where we say. 'it's worth trying any experience whether it's good or bad one'. No Fondue for the next 10 years probably!

The cozy restaurant in Chamonix

Yummy Fondue, and yet only bread and cheese. (Where is meat?)

It had been snowing for over a week in Chamonix. The town Chamonix Mont Blanc was presenting what I was expecting to see, and we were very pleased to come to Chamonix for skiing. We went to bed at 11 o'clock looking forward to the following days.


Happy New Year and All the Best in 2012!

It's 00:30 on the 1st January in 2012 in South Korea.
I wish you all happy new year and all the best in 2012.
There have been so many good news in 2011, and I sincerely appreciate for them.
In 2012, I will do strive for my PhD study in Oxford, and will appreciate for everything I undergo.
I promise this blog will be more activated and more frequently updated.
Any resolution in 2012??
Coming Up~

Lee Sun-Hee

Lee Sun-Hee

Think of the 1980's of South Korea and what comes to mind may be the settlement of democracy and 88 Seoul Olympics. For me, one specific figure comes to mind, and today for the first time in the history of my blog, I'm gonna introduce a Korean celebrity. Lee Sun-Hee (이선희) has been known one of the best female pop singers in South Korea. She made her debut in 1984 with one of the most well-known songs, 'To J'. Since then, she has recorded a number of extremely popular songs throughout the pop music history in South Korea. She has continued her musical works as a singer-songwriter until now.

There is no room for doubt that her singing ability is the best in South Korea. Needless to say that she's got a powerful voice, so her voice quite well fits into rock songs. Apart from her powerful voice, well demonstrated in the song '아름다운 강산', she has been loved by people for her sweet voice. It's extremely difficult to satisfy these two qualities, but she is capable of two extremely different types of songs with her unique color, and this is why she has been so successful. '나 항상 그대를' is my favorite song, and a number of singers have tried remake this song adding in various versions, but none of them is better than her version. 

She is particularly special to people in my age because most of her best songs came out in the 1980's when South Korea was going through a 'change'. In the 1980's, Seoul held two international sports events: Seoul Asian game in 1986 and Seoul Olympics in 1988. I'm not definitely in the position where I can say that these two sports events have contributed to the development of South Korea in terms of economics, politics and overall quality of human life. But what I can definitely say is that old generation strongly believe Seoul Olympics was the turning point in the economic development of the country, and it also presented South Koreans with a great confidence in global market. Right after the Korean War (1953), all the industries as well as residential areas were devastated. And after 35 years, the country successfuly managed to hold the biggest sports event in the world. Since the Olympics, South Korea has held World Cup in 2002 and will hold Winter Olympics in 2018. But now people's interest for those events is way less compared to 88 Seoul Olympics and now it's the government or big corporations that are extremely passionate about those events. The way to make the Olympics more valuable and meaningful is providing an opportunity to a developing country to hold the event because Olympics is a great opportunity for a country to get united and promote themselves in international market. 

For these reasons, I love South Korea in the 1980's. Many people claim that now South Korea is better than ever before, and I agree. Several economic indices such as GDP show that Korea would overtake America in a few years' time. There were a couple of economic crises as European countries are undergoing now, but those were easily overcome by Korean people by working harder and sacrificing themselves. Nevertheless, my favorite view of South Korea is still the 1980's since I understand the dream and hope for the future which the people in my parent's age had at that time.

Her best songs also include 'Run Hani' and 'Fate'. 'Run Hani (달려라 하니)' is an animated cartoon which was on the air in 1988, and Lee Sun-Hee sang the theme song of the cartoon. When I was young (at around 6 - 10), I had watched this over and over again, so there is no particular reason why I like this song. I just like it and so do most of people in my age. She also sang the theme song of the film, a Korea blockbuster, 'Fate (인연)'. Her best was in the 1980's, but she has been continuing her musical work to date. This movie was released when we almost forgot the presence of Lee Sun-Hee. And when the movie became a blockbuster in South Korea, the theme song also got significant attention. Since the movie 'Fate', I think she came back on TV shows, and now it's not difficult to see her on TV.

What's in your mind?

It's been fifty days since I started DPhil. For now I find it's not too difficult to fit my lifestyle into DPhil course. A couple of elements of my characteristic tend to drive me to work hard with enthusiasm, and I often enjoy some achievements usually coming from experiments and literature review. Apparently, I'm quite busy with ongoing experiemental works, and it seems this project will get bigger and bigger as I make it successful. My little concern is that, from time to time, I wish I could have more time to read journal articles to be more balanced between physical and brain work.

So, what's in my mind other than work, work and work?

First of all, I've made my decision 70% for skiing trip to Chamonix. I should've booked airplane and hotel during the last weekend, but my Saturday was messed up due to overdrinking at Wine & Cheese. I'm not going to disclose why I had to have beer after several glasses of wine due to his privacy, but talking about international politics was terrible idea. I must sort out booking by coming-up weekend. I believe it won't be too difficult to figure it out as I'm thinking of the same route and the same hotel, but it might be troublesome since Christmas is the busiest time of the year (probably). So, I better rush it!

Secondly, my laptop has never been the external threat to me while I'm living in the UK. Probably this is because I'm always prepared for any issue coming from softwares, and I don't much carry my laptop, so there shouldn't be a big mechanical issue. BUT, in the end, it seems to me that mechanical problem occured to my laptop. FAN ERROR. Still I don't really understand why this is happening to my laptop at this moment. The critical limit of life span of my previous laptop was a noisy fan. Given that nowadays nothing seems to be impossible when it comes to portable devices, it's quite nonsense that the first maintanance which PC requires is exchanging fan. Now I have to make quite difficult decision because this country hasn't earned much credit from me when it comes to service work, but at the same time, it's quite scary to keep using laptop having fan problem. I'll probably pop in PC shop in Oxford.

Thirdly, my first term is quite chaos. Now, it's week 7, so only about ten days left until Christmas vacation. Considering the fact that there is going to be almost no social activity organized by the college MCR during vacation, I might be better try more activities. Now I'm obliged to sign up for Christmas dinner because of my best college friend (?), and I'm also supposed to sign up for 2nd hall for day after tomorrow (Eventually!). Probably that's it. And we'll see I will be able to proceed research as much as I wish to do during off-term!

MCR dinner

On November 10th, it was my first MCR dinner in Oxford. On the day, late afternoon, since I was able to confirm that my current method of sample preparation won't work at around 6pm, I went to MCR a bit late at 7pm. My first impression of the dinner was that the people were relatively calm and peaceful probably because the people more energetic and keen for socializing were screened by the swap dinner with St John's College. Thanks to the swap dinner, I was able to meet non-fresher graduates in the college.

I hadn't been to the MCR, and my first impression for the MCR was small, cozy and mess like other ordinary MCRs. As a person who speaks English as the secondary language, it's not very enjoyable having a chat with someone who I don't know much about in a crowd. With said that, the idea of social connection through MCR is unique, and one of the best advantages of Oxford and Cambridge. Mixing up with people from different academic fields and backgrounds sometimes creates a distance in human relationship because they have less chance to professionally get connected. But, right before the dinner, and with a glass of wine, an engineer may find it quite interesting to know what a economist or a pianist is doing in Oxford.

In my college, MCR dinner does not take place at main hall, which is a bit disappointing in that the hall is quite beautiful and cool. Another surprising point was that there was no seat plan, which means you can sit anywhere. This could be good or bad, depending on individuals. As for me, it was not bad.

During the dinner, I met a fourth year Chinese DPhil studying physics. Actually, I cannot imagine how it would be like being a fourth year DPhil student. Needless to say that under massive pressure for thesis, and almost chaos due to job hunting or applying for postdocs. It's been just one-and-a-half month since my DPhil started, and still it's extremely difficult to judge the nature of DPhil. It seems to me that I am having more spare time, and enjoying what I am doing, but at the same time, it seems to be impossible to feel satisfaction and achievement from work. Sometimes, it seems like I am just working as an employee in Oxford ltd, but it requires academic depth. 

MCR dinner is definitely expansive, and I guess it's because of wine. Having a wine or not should be optional, and if the dinner price could be under 7 or 8 pounds, I would like to sign up for the dinner everytime.

Viva Voce

Looking back, viva voce was definitely defending myself from the attack.
And it'll be during my DPhil.

Could I finalize my mobile phone contract tomorrow?

When I was a college student, one of the lecturers has told us that mobile phone is depriving freedom from people. You are normally asked to give your mobile phone number when you try to join online networks. Then, what if you don't have one? The answer is that you are not allowed unless you get a new number.

Thesedays, mobile phone has become troublesome for those who are not particularly interested in other functions in it. As for me, there is little time to utilise a number of apps in smart phones, so I don't pay attention to the latest smart phone. Instead, the quality of phone camera is quite important because I want to memorise my daily life in Oxford. Even if I need to take pictures with no plan, I can't carry a camera all the time since it's heavy, bulky and probably more fragile.

I'm currently using one of the cheapest phone with no camera, so planning to purchase new one or contract a pay monthly. The criteria are now clear.

1. It has to be a major telecommunication company, so either O2 or Vodafone. For some reason, signal is extremely weak depending on regions, and Oxford is not a good place for this aspect. The first priority should be strong signal, and hence I prefer those companies.

2. It should definitely have a camera. As a result of the research on current mobile phones, 5 megapixel seems to be reasonable, so I would be happy with the camera with the resolution of over 5 MP. Paradoxically, some phones provide good cameras with no flash, so I'll have to double check if it has flash function.

3. Deciding mobile tariff is quite tricky and difficult. The best option seems to be either 18 months or 24 months, and I don't like either tariff. How could I possible know which phone is better unless I actually use it? Contract over 18 months with no experience is oppression by major companies and must be abolished. Having said that, 24 month contract offers £10.5 a month, and particularly Vodafone offers 100 minutes call and 500 texts.

I guess I should choose the cheapest one because most of my phone call is international call, and this is not included in the £10.5.

4. I don't need a smartphone for the time being. It might be neccessary to keep myself away from the internet at least on the street or in Tesco because I have to spend significant time with the internet for my work.

I've decided to let myself left behind the cutting-edge mobile phone for the next a couple of years. But, instead I need to pay attention to the progress of mobile phone technology as a PhD student working on MEMS.

Now it became more clear which tariff and which phone I should choose tomorrow. Be decisive and quick with no hesitation.

Managing your DPhil

Doctor of Philosophy =
physical work +
minimum brain power (99% human being has this) +
language +
what else??

Several days ago, I took 'Managing your DPhil course', by the lecturer, a PhD degree holder, from Imperial College. This course seemed to be mandatory to new DPhil students, so I went to the lecture room with no hesitation. Surprisingly, there was no one other than the lecturer in the lecture room. Recently, I often get surprised by my amazing punctuality. Being puntual at a meeting or whatever and waiting for others to arrive make me feel quite nice than you imagine.

This session was booked for the whole afternoon (1 to 5 o'clock). I knew it was going to be a waste of time and actually it was. Four hours is ridiculously long to learn how to manage my doctoral research. The content of the session was quite predictable, and indeed it covered stuff like time management, plagiarism, originality and etc.  

Since I came to the UK, I've taken quite many training courses such as presentation skill (particularly several times for this one) and various kinds of management skills. Fortunately(?), I've never got bored from those sessions, thanks to the language. It requires high concentration and good listening skill. To me, it's quite impressive to see how British people pay attention to this this kind of sessions.

Despite the fact that four hours of managing your DPhil was obviously over the top, I have to say that the course was quite fruitful. During the course, I had to think about 'Why?' for a couple of factors associated with DPhil course, and it was a good opportunity to clarify more specific goals. For example,

What a DPhil is?

'Demonstrate your ability to conduct research, understand your subject, demonstrate critical and independent thought, show originality, contribute to knowledge, develop a model, explain and defend a model and so on.'

These are most of factors and qualities which I should always bear in mind as a DPhil student.

Another interesting point in the session was 'The Pareto Principle'.

'The 80:20 Rule.

A minority of input produces the majority of results.'

This implies several good points and suggestions to DPhil students. First and foremost, it is very likely that you will waste your time by sticking to one particular experiment. Success or failure could be determined by your extra input and effort, but it is less likely to happen. Trying to be well oriented is much more important than just hard working. Secondly, do not focus on just your work during your DPhil. It might be wiser to try to drill your other skills with your main work so that I can efficiently utilise the 80% of my time.

So far I feel doing DPhil is not tough as much as doing MPhil, but you should always bear in mind where you are, where you are heading, how you are doing in longer term. Probably, doing DPhil is another step to become more professional.

Sporadic enjoyment

It's been approximately twenty days since I came to Oxford. It was quicker and easier to settle down in  Oxford since I've gone through the initial setting-up process a year ago in Cambridge. I've got a bike, bank account, mobile phone and etc, so was able to begin normal daily life from the second day in Oxford. Yet, my life is still nevertheless inefficient, inconvenient and uncomfortable. There are only several streets and roads I've become familar with so far, and just a couple of shops where I am going for shopping. I've not been inside any college other than my college, and haven't taken any photo yet.

To analyse this, I think, I'm not rushing it and there is no reason for rushing it. I will be here for three years (to say the least). Interestingly I've never lived in one city more than a year in the UK, so three years seem to be extremely long to me. Here is a good analogy. Jinju Castle is one of the best cultural heritages in South Korea, so tourists across the country travel to visit the castle. But, surprisingly, I've been to the castle just a couple of time though I've lived in Jinju over twenty years. Once you're aware of that it's always there whenever you reach your hands, you don't try hard to get to know it.

At the same time, I'm also afraid that I may get tired of this old town too soon. Since I haven't looked around the city, Balliol College, which I pass by everyday on my way to my college, looks like a classic castle, and Queens College, which I come across on my way to the pool, is mysterious and magnificant college for me. The easiest and quickest way to become familar with this city might be taking a city tour bus. It probably takes you around most of important and beautiful places in Oxford in one and half hours. But I want to leave it for a while.

For me, the best way to enjoy this town is letting Oxford sporadically and randomly get into my eyes, and the enjoyment will be maximised when I get tired of the routine work.

My baseball philosophy

Sports is addictive as much as internet. Nowadays, professional sports leagues have become a huge industry in a number of countries. In South Korea, football and baseball have been major sports for the last several decades. Despite the fact that Koreans tend to take international football matches seriously like other countries do, Korea professional football league (K-league) has never been a big success. First of all, it is hard to watch K-league on TV since it is not attractive sports from the viewpoint of broadcasting companies. Broadcasting companies seem to be relectant to put K-league games on the air because of the less economic benefit from commertials. They can utilise only 20 minute break between the first half and the second half in football, so this is definitely not a beneficial sports for broadcasting companies. By contrast, Korean professional baseball league has become a 'blockbuster'. Surprisingly, baseball has become a super hit in both professional league as well as international matches, and people love to watch baseball either in stadium or at home. Besides, broadcasting companies, in fact, way prefer baseball since they can insert 15 minute commercials  between every inning and whenever pitchers get changed. After Beijing Olympics and WBC, more people have visited stadiums to watch heros' plays, and once boom was created, more people started travelling to baseball stadium to enjoy the fever and atmosphere.

What I intend to argue today is not the present and the future of Korea sports or anything like that. Once you are addicted to something, it is quite difficult to just ignore it. I am a big fan of 'Kia Tigers', which is one of the teams in Korea Professional Baseball. Being currently in the UK, I've been consistently checking all the news associated with this team. Given that Korea Professional Baseball is around 30 years old, Kia Tigers has been the most successful team by winning the league for 10 years. The fans are not limited to the home city Gwangju, and this team has secured supporters across the country. Accordingly, the expectation from the large number of fans is enormous, and the manager is always under signifiant pressure and criticism. Because I understand that the position of the manager of Kia Tigers is difficult, I have been generous about his leadership and the result. But, today I intend to brutally criticize his baseball philosophy, and strongly believe that it is the time to change the manager.

First of all, his philosophy on baseball is doubtful, and the success highly relies on the performance of only several top players. He put a high value on the quality of pitchers rather than that of hitters. He believes that the performance of pitchers is more stable and consistent than that of hitters. As no hitter can achieve over 0.4 batting average, baseball has been known as the game of pitcher. With said that, having just several good pitchers is quite risky, particularly when there are not enough reliable bull pen in the team. In this year (2011), Kia Tigers had the excellent three pitchers, and the manager intended to take advantage of them. The earned run average of these  three players used to rank in top five during the first half of the season, which means that any one of three could be the ace of other teams. The manager's strategy was quite successful in that Kia Tigers was placed at the first in the league table at the end of the first half of the season. Since these pitchers were capable of dominating the game by the seventh or eighth inning, the hitters in the team got less pressure, and hence they were able to bring their the best. Even though the bull pen in the team was critical weakness, they used to be able to finish the game in the lead. In 2009, and the first half of 2011, I must say, his strategy did work.

In 2009, Kia Tigers was well known for the strongest five starting pitchers including two foreign players. Lopez has been playing in Kia Tigers for the last three years, significantly contributing to Kia Tigers (he should've been absolutely the MVP of Korean Series in 2009). Rick Guttormson has won 13 games in 2009, with earned run average of 3.24. (He had to leave the team immediately because his performance during Korean Series was not impressive compared to Lopez). In 2011, three starting pitchers (Yoon Suk-Min, Lopez and Travis) showed fantastic performance every single game until the summer break. In particular, Yoon Suk-Min and Lopez were ranked at the first and second place in several league tables such as earned run average.

However, the second half of the 2011 season showed the critical weakness of Kia Tigers, which was the injury of the key players. Because the team was relying on the ace pitchers, they had to be in charge of as many innings as they could, which in the end brough about injury. As soon as two foreign pitchers' condition fell down, the bull pen pitchers had to play longer innings, but bull pen also requires enough break time for recovery. Therefore, the ace pitchers' injury got the entire team to get trapped in a vicious circle.

Given that every team is allowed to have two foregin players, there have been just one Korean ace pitcher, Yoon Suk-Min, who differentiates Kia Tigers from the rest teams. This means that for the last several years, the coach has failed to upgrade bull pen and pitchers. In fact, bull pen is extremely important when it comes to professional baseball league. Having a group of good bull pen means that the team is less vulnerable to the injury of aces. Besides, it provides reliability to the team, so hitters can concentrate on games up to the last inning in games. As long as there is good bull pens, there is no collapse.

Secondly, a combination of one foreign hitter and pitcher might work better rather than two foreign pitchers. In 2011, Kia Tigers had four home run hitters (Kim Sang-Hyeon, Choi Hee-Seop, Na Ji-Wan and Lee Bum-Ho), but this fantastic line-up has never played its role properly since most of them had to suffer from injury. Nevertheless, it is worth noting that Kia Tigers was the top in the league table when three of them were able to play in their good shape. Having another good pitcher affects one game out of five or six games, but having another robust home run hitter contributes to the overall performance of the team. Travis who is one of the foreign pitchers in Kia Tigers ended up with one of the worst foreign players in 2011 due to both his injury and bad temper. It makes me think of 'what if Kia Tigers had another home run hitter rather than pitcher?'

The next year is the last season for Cho Bum-Hyun as a manager of Kia Tigers according to the current contract. His success is very likely to be entirely up to the performance of a couple of ace pitchers and hitters in 2012 again. As a fan of Kia Tigers, I do not want to see another victory highly dependent on luck. Even if Kia Tigers cannot be a winner in the next season, I wish the team could have more sustainable and consistent performance, and it's only possible with a stronger bull pens and more consistent home run hitters. This is why most of fans are speaking up for Sun as a new manager in Kia Tigers.

I took a Citi Tour Bus in Cambridge

Today (August 31st) was the last day in Cambridge. I've come up with several plans for the last day in Cambridge, and I decided to go with taking a Citi Tour Bus. I thought this is the best way to store all the memories in Cambridge for the last one year. Taking a tour bus is always exciting because you can feel all the energy from other tourists.

Surprisingly, there was 3 pound discount for students, so it costed me 9 pounds (ouch!). Deciding to take the tour, I was looking forward to discover new places which have historic significance. Unfortunately, however, the bus took me to the places where I've routinely passed by due to lectures and libraries. I honestly felt really nice in that my daily route was the heart of Cambridge!

I have to say that Cambridge is extrmely gorgeous, classic, beautiful and strong. I think I successfully sealed my memory pocket of Cambridge. FAREWELL!

August is not ideal season for open double-deck bus
