I hope to continue working on my blog, after more than one year blank. The social networkings boost, and I have more experience among connecting people and informations. The blog is a good field for me to cultivate. Today, I change the Header Image of this Blog. I took this photo (Luzern_Picasa) when I traveled to Luzern in 2007. I like the image with blue sky, blue lake, and beautiful buildings. About the Physics and Music pages, I don’t plan to modify them at this moment. Please forgive my laziness.
