Physics Reunion

Today is the first day of my first termal physics class of the semester.After eating a wonderful breakfast, I walk to my physics lecture hall.It has such a long time since I step into the same lecture hall.I was exited because I really miss the comfortable theater-like lecture hall.I like the lighting and the comfortable chair.I remember falling asleep almost every single time when I had my physics lecture over there. Once I step into the lecture hall, I saw my lecturer. He has white and curly hair just like those of Albert Einstein. Maybe the "physics people" just use their brain too much.Haha....Then when my first lecture actually begins, I found that how fun and interesting it is to have so many cool demonstration. Right after my first lecture,I have my discussion section. I realized that I have to make use of all the previous knowledge about momentum and kinetic energy which is a bad news for me because I just hate everything about kinematics.Then,I have a difficult time catching up in my discussion group because everybody just seems to be so smart.Sigh....At the end of the class,my TA comes up with a conclusion that most events that happens in nature are irreversible. Ya,at least I can apply physics in real life.Things that have done can rarely be re-done.
