My major

I major in physics. For one thing, I like physics. But I have 3 classes this semester. When going slope up, I've felt like ''ah, mgsinθ prevents me from going up, however, my mgh is growing!!''

The other, that is because there are many things to study.
My collage has many area of studying, that is exciting to me. One is studying with X ray, one is studying about space. Actually, I don't know what professors or others studying very well, however I know a little bit of the utility.One example is GPS. We are owe it to physics that we can know where we are. If you want to know it, you have to make it calculate how some information is affected by gravities and the speed of light.
