It's not that bad, as long as plans are well made. Feeling miserable now is because I was too lazy over the 1st year, when I learned almost nothing new. Classes taken in the 1st year were actually already learned in undergrad study. Passing quals is a piece of cake for Chinese students. What I should really have done was to learn driving and pass the SPEAK/TOEP test, but I failed to.
Now the 2nd year comes. "Sophomore = suffer more" also applies to grad school. It's time to work hard to learn some new stuff, not just physics stuff, but also some math stuff. Taking some math classes, I realize math is a total different thing from physics. Physics is real. If you say a car driving at 90mph, I can imagine there's a car on a freeway. I can imagine it moves very fast. It takes about an hour for this car to drive from Irvine to San Diego, if it doesn't get in trouble with the police. Math, however, is abstract. A simplex in 2-D is a triangle. In 3-D it's a tetrahedron, like a pyramid. In 4-D or n-dimension, it's ... uhm ... it's ... Damn it! What the hell is it?
