2. How is the fabric of society today different from pre-internet society? p. 31

3. How many more links separate any pair of web pages compared to people in society? What can explain the difference? p. 34
Any pages of the Web is on average nineteen clicks away from any other, while people in society are separated by only six other people. The difference between six to nineteen is caused by the factor that the Internet is huge far more than our society.

Network scientists discovered a wide variety of networks, such as, network of food webs, mollecules in the cell, scientists in different fields, and the neurons in the brain of the C.elegans.
5. What does research suggest about the fundamentals of networks? p.34-35

6. What is your estimate of your personal number of connections to society? What connections are your strongest?
I'm not sure about the number of connections, but maybe I have almost ten type of connections to society so far. For example, family, schools, cram schools, neighborhoods, church, piano, intern, part-time, volleyball club, and getting friend with someone who is friend of a friend. And I think the connection related to my school days is strongest.
