Things to say about my HW this week

This is the 7th week of our second semester. Although this is not a busy week because all the exams and works that happened in the last week, but still we have some work this week. I read a article called "One Hundred Years of Multitude." You may think the title of the article is quiet familiar, because it is a allusion of the book One Hundred Years of Solitude by Gabriel García Márquez. The article mainly talks about different groups of people, like Asian and Slavs. This makes me think about the world that we live in. It the world that have tons of different cultures, races, and countries. In the past, people often time united due to a common races and nationalism, and they fight with the other groups of people because they wanted to prove their superiority. But now, people cooperate internationally, disregard their country and nationality. I found it interesting because I was wondering what is the force that cause people to turn fighting into collaboration. Is it the world-wide economy? Or because they are tired about war and fighting?
