Example Input: Complexity through connections . The work of Duncan J. Watts was admittedly inspired by the work of social-psychologist at Harvard University, Stanley Milgram, in the late 1967 on experiment on the problem called "small world" problem: "anyone person in the world could be reached through a network of friends in only a few steps; in Watts language, "after the cocktail party banter in which two strangers discover that they have a mutual acquaintance and remind each other what "a small world" it is. Surprisingly, Milgram's results led to the phrase "six degrees of separation": the degree of network of friends between me and you will never be more than six! I know someone who knows someone who knows someone else who knows someone that knows someone who becomes my friend! I feel a must to urge the readers to read the book in order to understand further what science of network can give us. Among the popular books of networks, reading Watts' Six Degrees is important since the book was made seriously by the author for unlimited readers. It is a time for physics gives something valuable on constructing new scientific sociological work to day. Hokky Situngkir Bandung Fe Institut

Example Input: JOB APPROVAL DOWN TO 38% . and falling...The cover photo makes Bush look thoughtful, somber and deep. What a crock! The president isn't "misunderestimated". If anything this administration was given a free ride after 911. (Where IS Cheney, BTW?) And Dubya, who has yet to string together a coherent sentence, is an embarrassment. That vaunted Yale degree has to be courtesy of the elder Bush's wealth and connections. How can Bill Sammon can write such tripe in the face of this inane war, nation-building, huge deficits, and the sophomoric, cavalier mentality of Bush? Hey Sammon, we've now been in Iraq 2-1/2 years. It isn't enough that we've donated several hundred billion to build state of the art hospitals, roads, electrical grids, etc. for these people? BTW, there is concern there aren't enough educated Iraquis to actually operate these facilities. It isn't enough that Iraqis gas up their vehicles for pennies per gallon while U.S. citizens pay ridiculous prices. The Iraquis are still letting our people do all the heavy lifting - and dying. Only 1,500 Iraqui troops are adequately trained to date? You have to wonder if these people have the desire or the guts to defend their own freedoms. Speaking of defense, when is Bush going to do something about the southern borders with Mexico. Illegal immigration is up 23% since this man took office and we are paying a heavy price. AZ and NM have already declared a state of emergency. Texas is overrun. Illegals are overwhelming schools, emergency rooms, welfare systems. Meanwhile Bush bicycles on his 1600 acres of Texasss brushland, kisses Vicente Fox's behind, panders for Latino votes to maintain power, and refers to peaceful U.S. citizens trying to monitor our borders as "vigilantes". But he protects the borders of Iraq and Afghanistan with our military. This man is at the least incompetent, and at the worst treasonous. I'm embarrassed to admit I voted for this dumbkopf.
