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 of separation is that two people in anywhere in the world are linked by only six social links. It means that a parson is connected to any other person mediating about five people.
2. How is the fabric of society today different from pre-internet society? p. 31
The fabric of society today is different from pre-internet society because the collection of individual documents are linked in a huge web network. People have became able to access to other people's document easily and quickly with the internet.
3. How many more links separate any pair of web pages compared to people in society? What can explain the difference? p. 34
Any pair of web pages is "nineteen degrees of separation" and people's one is "six degrees of separation," so web pages' link has thirteen more links than people's one.
The biggest difference between web's society and people's society is that to find every links on the network is easier in the web's society than people's society because to find every links between one person and the others is almost impossible.
4. So far, what ranges of separation have network scientists discovered in different kinds of networks? p. 34
The network scientists discovered that every networks which were examined display separation between two and fourteen. For example, "species in food webs appear to be on average two links away from each other; molecules in the cell are separated on average by three chemical reactions; scientists in different fields of science are separated by four to six coauthorship links; and the neurons in the brain of the C. elegans worm are separated by fourteen synapses." Therefore, the web's nineteen degrees of separation is the largest record.
5. What does research suggest about the fundamentals of networks? p.34-35
The logarithm can make the huge network to the small world. (I am not good at math so I could not understand why logarithm can do such a thing.)
6. What is your estimate of your personal number of connections to society? What connections are your strongest?
I cannot believe that I am connected to every person in the world mediating 5 or 6 people.
I have no idea about my strongest connections.

Lesson3: blog post - Think, Explore, Explain
Think:
What arrangements do you have to make now to be able to work on whatever you want to wherever you are?
The Web Browser in the USB drive. It can be able us to work easy for essays or anything else on the computer.
Explore:
View a couple of these screenshot tours 1 2 3 4 showing how different users have developed a personal work environment in Firefox (FF). Most users have provided details on what extensions or tweaks they've made to develop their browser as a personal work environment. Take notes on some of the features that look interesting.
In the screenshot tour 1, I thought Pasha's "All-in-One Sidebar" seems useful because it shows the sites which I access frequently.
In the tour 2, I found that Adam's "Menu editor" seems good because I can organize the various sites easily.
In the tour 3, I felt Thomas' one is cool.
In the tour 4, I thought Wade's "Split Browser" is very convenience because I can do two or more things at the same time.
Explain:
Write a post reflecting on Firefox (especially the add-on you have learned to use) with reference to the four Key Questions.
Social Computing Key Questions:
1. What are the main skills needed to use social software?
To install the social software to the USB drive.
2. What are the affordances (what the software makes possible, what it impedes)?
People can organize their internet life easily, and they can carry out to anywhere they want. However, it cannot be used without computer, so depending this technology deeply is danger.
3. How can the technology be used to network professionally and connect users to learning resources?
People can search sites with their organized own Firefox.
4. What learned skills and understandings may promote your development as an effective learner in the digital age?
I can search on the internet more easily.

Lesson2: blog post - Think, Explore, Explain
Think:
What arrangements do you have in place now to be able to show others (and to yourself), what you know and what you can do?
I think the blog is a good way to show what I know and what I can do. Also SNS site like mixi can show them.
Explore:
What main benefits/disadvantages do you see (if you see any) in the design of an e-portfolio compared to a traditional resume?
Benefits: It is easy to edit and carry out if people use an e-portfolio.
Disadvantages: People cannot see their e-portfolio without computer.
Explain:
Write a post reflecting on your blog as an e-Portfolio with reference to the four Key Questions.
Social Computing Key Questions:
1. What are the main skills needed to use social software?
People need the skill to use a computer. (I'm not sure about this question)
2. What are the affordances (what the software makes possible, what it impedes)?
What the software makes possible is that people can make contact with other people. However, it is difficult to save people's personal data.
3. How can the technology be used to network professionally and connect users to learning resources?
The network can be used to research on the internet.
4. What learned skills and understandings may promote your development as an effective learner in the digital age?
To use Databases, to search official sites, etc...

Lesson1: Barabasi - The First Link
1. What elements or factors were critical to Paul's success in spreading the Christian message?
Firstly, Paul abolished circumcision and the strict food laws. In addition, he exploded the message using the social network; he walked about 10,000 miles in 12 years, spread the Christian message to the biggest communities which had many people. He used the social network effectively, and that is one of the critical factors to Paul's success.
2. Barabasi asks the question, "Could it happen again?" (p.4), what is your answer?
I think it could happen again, but the way to the success is different from what Paul did because at now people can use another kind of social network; people can make conversations without being face to face. Also I think the chance of the success like Paul did is very low because at present, people have lots of information and they can choose what they believe after judging the information.
3. What new kinds of maps have been made of our interconnectivity (p.5)? What kinds of interconnectivity would you like to see mapped?
Firstly, maps of the internet have been made, and they have told the people about the internet's vulnerability to hackers. Secondly, maps of the companies which show the links of trade or ownership have been made, and they have made people to be able to trace the trail of power and money in Silicon Valley. Thirdly, maps which shoes the interactions between species on ecosystems have been made, and they have told people about the humanity's destructive impact on the environment. In addition, the maps of genes working together in a cell have provided insights have been made, and it have shown people how cancer works.
I want to see the map which tells how the languages of the world are connected with each other.
4. What is the 'real surprise' (p.5) that such maps have revealed? Personally, does this surprise you?
The 'real surprise' is that these maps have the similar or the same blueprint though the maps are very different from each other. Actually, this structure and evolution of the complex networks are governed by the natural laws.
Personally, I was surprised because I did not know that the basics of those maps are the same even though their categories are completely different from each other.
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)?
The author defines the nature of most scientific research in the 20th century as Reductionism. The notion of Reductionism is that people have to divide the nature to its constituents to understand the whole; people can never understand the whole without considering the constituents.
However, the problem of this approach is that people became not able to put the constituents back together to understand the whole of nature. It was very complex because nature consists of the all-encompassing laws of self- organization.
6. What does Barabasi predict will be the new focus of scientific research in the coming era (p.7)? What is your view?
Barabasi predict that the networks will dominate the new century, and he claims that everything in the world are linked together and to understand the networks which link everything is most important. I think that to investigate the details and to understand the networks are both important, and to see the networks after investigating the details seems good idea.
