Today began with a class in the morning. We were lectured on the principles of ultrasound and how sound waves work. I enjoy how similar the content and lecture style is between America and Korea. It is a certain kind of reassurance that what you are learning is universal. Later on in the day we took a bus and subway to a professional baseball game. It was much smaller than in America but the crowd was completely different. They were so much more organized and involved in what was going on. I got tired just watching them sing and cheer.
