This Jun. I was lucky to be elected by IAESTE-CHINA as an intern to work in the Laboratory of Computational Engineering of Helsinki University of Technology, Finland for 3 months, from 8th, Jul. to 31st, Aug.

Life
The first few days after I arrived in Finland, all is new to me. Fortunately, I can accustomed to the new situation and get to work as soon as possible with the great help from the lab secretary, Eeva Lampinen and from the oversea Chinese student in the same lab, Wei Zhao.

Fortunately, there were always time when I can come across some Chinese people, who, although very busy and only hastily nodded as regards when encountered, will help me in their power as I needed. Here there is a list of email addresses of thousands of Chinese people and local people, whose function is as bbs. People can exchange supply and demand information, publish opinion and offer help to others. Moreover, I made some friends in life, who were much elder than me and studied abroad for many years, thus had different opinion on various things with me. This intercourse is wonderful.

When half of the summer passed by, there came 2 people to share the same flat with me, one from Italy and another from Germany, who made the calm and somewhat tedious life colorful. Every night, we chatted about the difference between China and Europe, our research subject and individual life for long time while drinking beer. The differences between cultures always attracted most of out mind. And drinking beer was so popular here that a few words I knew in German and Italian almost were about wine.

They got used to the circumstances more quickly than I, beginning to deal everything with equanimity within 3 days. When it comes to communication, they still did better than I. Although other associates were polite to me, I felt that there was a lack of common ground, which I regarded valuable and important.

Work
Originally, professor Mikko Karttunen, who was in charge of me this summer, made a search plan for me. But after the previous contact he took some interesting in the topic of my thesis for bachelor degree, which covers about using the numerating physics methods of monte carlo simulation, cellular automate etc. to simulate the accumulating phenomenon of the Alpha-synuclein protein that occurs in Parkinson's disease.

In respond to it I made a lanternslide and a presentation on this topic at the first period of time. Maybe it is because this topic was novel and can integrate the two fields of physics and molecular biology that it attracted considerate attention and the professors and most of the graduates on work attended it. Moreover they took interesting on this topic too after my specified presentation and several times full discussions afterwards. Mr. Karttunen decided to let me go on this research and appointed one of his postdoctors, Michael Patro, to cooperate with me on this topic and offer concrete guide and help to me. He himself often discussed with me over the process of my work and problems encountered during research.

Mr. Michael Patro helped me a lot for my work, for what I was mostly concerned about was the concrete physical process corresponding with the program while I cared little about the exactness of the outcome or the running speed of the program. With his help I almost rewrote the whole source code and thus got the outcome more coincident with the facts. Then we discussed how we can go further on the basic of this program to take the influence of the abrupt changes of protein over the whole process as a controlling factor to the whole program into consideration. Thus we can compare our outcome with that of our cooperator in Shanghai from the same experiment to explore the mechanism of this disease. Because of establishing farther cooperating relationship, Mr. Mikko Karttunen made extremely specified request about the data from the biochemistry experiment. So I have visited the cooperator of Shanghai after returning to China to make a first-hand investigation and I have learnt about the equipment there and gained a approving result. It is a god-given chance for me to cooperate with them in this field.

This project I finished independently during my undergraduate years, from setting up the topic to coding. But they didn't regard it unimportant and on the contrary, they respected my choice though I was only an undergraduate. Indeed we got approving result through the approximate 2-month's work., as is unthinkable in China.

Impression
This summer in Finland was the first time I went abroad, and went to such a country with so many differences with China. During this period of time I took part in several activities held by local IAESTE and went out with my roommates for several times. Sometimes I went to enjoy pop music concert or fireworks performances at night, went out to the gulfs near Helsinki to get close to nature on sunshiny weekends, walked on the ever-bright avenue of Helsinki with several friends, and even alone strolled in high streets and back lanes of Helsinki which is full of North-Europe characteristic ---- I gradually entered into the city, the country.

Most interesting thing in my impression was that on many of my photos taken by local people who I ran into myself was highlighted while the nearby resort was vague, not liking the composition of pictures taken before in China, on which resort was often highlighted while my portrait was a little small. This respecting people circumstances cannot fail to be seen in Helsinki: in Helsinki, even in residential are, where there is a little bigger street, it is surely be divided into two parts, one for motor vehicles and another for people walking or riding bicycle. And the latter one is almost as big as the former one except on motor way. When road was being repaired, the pavement is always first to be dealt with before the part for vehicles to be. Nearly every family there possesses car though the brand and performance of the car vary greatly: from the most popular sports-car to outdated car which overruns tail gas and even in China is on the verge of outdate. But every one is calm while driving car: people who drive sports-car don't take it pride and people who drive outdated car don't think it embarrassed. I can still give many other examples of this kind which indicate that every one lives on their own choice and the prosper, equal and highly welfare society mechanism fully guarantee their free choices.

I remembered one puzzling thing occurring when I just arrived there was that when I went shopping in supermarket I found that, whatever long queen was waiting before the check desk, the check ladies would always express greetings to customers at leisure by nodding and smiling before orderly checking merchandises one by one. Also I found that in constructing site the workers seemed to work very slowly and at great leisure. Once at a time I happened to chat with an oversea student who majored in Engineering Control about this phenomenon and expressed my puzzle: it is not the case that Finland must be highly efficient as I originally thought, for it is such a small country with only 6 million populations but can make out international brand like Nokia and its national income is in the first class of Europe. But that student argued that this work style is the most efficient way, which although seems not to be very quickly but does thing well at the beginning without any bad tail. And it is the most economic way too.

The 2 months in Finland only can offered me general view of local conditions and customs like skimming over the surfaces. It passed so rapidly that I soon had to leave. But I felt very lucky to have this chance to enable me wide my horizon. This nice period of time is forever a wonderful experience for me.
