1. What is the principle of six degrees of separation? What number of social links does any one person need to be connected to global society? p. 30
The principle of six degrees is that it can easily be navigated by following social links from one person to another.
One person needs only five people and six links to be connected to another person.
2. How is the fabric of society today different from pre-internet society? p. 31
People became to share their knowledge with other people on network by a few click of links.
3. How many more links separate any pair of web pages compared to people in society? What can explain the difference? p. 34
There are 13 more links in web pages.
4. So far, what ranges of separation have network scientists discovered in different kinds of networks? p. 34
There are two ranges for food webs, three ranges for molecules in the cell, four to six ranges for scientists in different fields of science and fourteen ranges for neurons in the brain of the C. elegans worm.
5. What does research suggest about the fundamentals of networks? p.34-35
There should be more links to make the network's world smaller to connect each other.
6. What is your estimate of your personal number of connections to society? What connections are your strongest?
I think I need more than six degrees because I do not have much acquaintance so it is difficult to be connected to a lot of people in the world. I think it can be close to six degrees when I become more old.

Homework : Barabasi
1. What elements or factors were critical to Paul's success in spreading the Christian message?
There were two reason for his succeed. First, he made the high barriers to becoming a Christian lower so that people could become Christian more easily. In addition, he used the social network to spread the Christian message to many people.
2. Barabasi asks the question, "Could it happen again?" (p.4), what is your answer?
No. Nowadays, there are too many information on the Internet and TV and so on so that there would be no impact to people as same as the Paul’s time.
3. What new kinds of maps have been made of our interconnectivity (p.5)?What kinds of interconnectivity would you like to see mapped?
The scientist’s maps which offer surprises and challenges. There are kinds of maps of the Internet, maps of companies connected by trade or ownership, maps of interactions between species in ecosystems and maps of genes working together in a cell.
I want to see a maps of countries connection of sharing technology knowledge.
4. What is the 'real surprise' (p.5) that such maps have revealed?Personally, does this surprise you?
The 'real surprise' is the fact that any diverse map follows a common blueprint.
I was surprised a little bit because if there were no any exchanging information and it had happened, it means that all people made up a same way to solve their problems of needs.
5. How does the author define the nature of most scientific research in the 20th Century? What is the problem associated with such an approach (p.6-7)?
Reductionism was the most scientific research which told us that we first must decipher its components to understand the nature. However, the way to make the nature back is not easy by one way and it takes billions of years for us.
6. What does Barabasi predict will be the new focus of scientific research in the coming era (p.7)? What is your view?
The connection of linking each other by networks. I think so too. Without the Internet, it will not be the acceptable way to get knowledge.
