It's only the third week of the semester but I got to do homework all the time. If I were in Taiwan, it should still be a leisure time. As a matter of fact, the most difficulty remains arising from my English deficiency. For instance, one of the lecturer teaching my corrosion course is from Italy. It's really not easy to understand his accent. On the other hand, I am very weak on chemistry and electro-chemistry is so related to corrosion so it's indeed tough to me.
Another lecturer teaching the course, "Interaction of radiation with matter", is a gentleman on his age of 80. The way he talk is really a murmuring to me. So all that I can do is to take notes. Even though he is so old, I am sure that he is still clear-headed. When he started teaching, he just wrote down what he murmured immediately without taking a glance at his note. In conclusion, he is good. By the way, I heard that he is the first Nuclear Engineering PhD in the world. If true, that's pretty cool.
Conversely the situation is quite different in Taiwan. A professor is forced to retire around age of 65. Sometimes they would like to retire as soon as possible. I think the professor who insist on teaching and research whole life is really respectable.
