Busy but fulfilling DaysWeek 4---Undergraduate Students from the College of Optical Science and Engineering did Scientific Research in Boston University during 2018 Summer

Aug 06

The students who participate in the Summer Research Program have been in Boston, USA for more than 20 days. Although we gradually adapt to the living, studying, and socializing in the United States in the process of continuous experimentation and exploration, we still encounter new challenges again and again. These challenges are largely based on scientific research. And when it comes to research, we have to say weekly meetings.

The different research groups at the Boston University Photonics Center conduct two or three group discussions each week. The students prepare PPT and lecture notes, present their own research progress, problems encountered, strategies for response, and further research. The plan is followed by enthusiastic discussion and questioning. A very "strong" group meeting will be held on Wednesday. The current research of the group is mainly divided into two parts: the stimulation of neurons and the photoacoustic conversion module.

And part of what we are attending is about the photoacoustic conversion module. After a period of time spent on sleepless nights modeling and calculation, we have better repeated the results of a paper, and mapped the images that are very similar to the results of the paper, but also found the high-frequency carrier components that were not found in previous papers. For this issue, there was a heated discussion at the group meeting. Some seniors are the first to propose whether there will be errors in our model or errors in calculations. Some people think that it is the high-frequency component caused by the problem of iterative convergence, and the high-frequency component that the seniors think is its own particle resonance. At the scene, everyone discussed the atmosphere, the various views of the confrontation, and finally the instructor asked us to change the size of the structure to find out whether the results will change.

There is a discussion on literature discussions every Friday. People from all majors, fields, and research directions will come. Everyone discuss a new emerging problem or research direction. Every time, a doctor will give a lecture and discuss the questions. After that, everyone will have lunch, we can often see some researchers eating and discussing, and even forgetting to eat and pick up paper and pencils for calculation analysis. In these days in Boston, we realize the rigorous and realistic learning and the dedication of selflessness in science. These are all we need to learn.

Compared with the strict atmosphere of research, tutors of Boston University put much stress on the cultivation of lab environment and culture. Just on this Thursday, one of us took part in a group lunch with his tutor and fellow graduates. Through the gourmet and lunch conversation, we get to deepen our friendship with lab mates and get to know more about American culture in lunch parties.

At first, it is the active guys in the group that raised an invitation through email, and everyone expressed his opinion and offers suggestion on the selection of time and place. In this way we can avoid possible situations that someone might not be able to spare time for the lunch, or not be able to relish the meal out of personal affairs or cultural reasons. This process is inevitable specially for a diversified team.

When the day came, we gathered in the lab and headed for the restaurant together. We had decided on an Indian restaurant. The restaurant was not crowded, and was decorated in Indian style. Waiter had us seated in a table in the middle. The recipes on the menu all have simple notations explaining the ingredients and cooking techniques lest customers might not understand the terms of food.

Tutors and fellow graduates enjoyed a lot in their conversation while having their lunch. Different from the serious attitude in the lab, it was relaxing during the meal. At that time, there was no distinction between teachers and students, and nation and culture did not seem to matter so much as well. Chinese, American, Kenyan, Turkish and Russian just sat around the same table. The topic of peoples dialogue also changed to families, hobbies and sports. At the end of conversation, we were surprised to find out that the Turkish of our group had a ping-pong certificate. A Chinese in the group, who is also good at ping-pong, decided to play with him some time.

Two months research experience might be short, but we are sure to have a strong bind of friendship with professors and fellow graduates here.\
