A field of mathematics six dimensional theory
conjecture, called Six Degrees of Separation, Chinese translation include the following: six degrees of separation or the small world theory etc.. Theory suggests that: between you and any a stranger interval not more than five, that is to say, by at most five people and you can know any stranger, see chart. This is the six degrees of separation theory, also called small world theory.
meaning small world phenomenon (also known as the small world effect), also known as the six dimensional theory, six degrees of separation (English: Six Degrees of Separation).If in the world all strangers with only a little man in the middle can establish contact. Later Stanley Milgram professor of psychology at Harvard University in 1967 according to the concept of a chain of experiments, trying to prove that an average of only five people can connect any two strangers americans.
this phenomenon, is not to say that any human contact with other people must connect through six levels only, but expressed such an important concept: any two people be strangers to each other, through a certain way, can always have inevitable connection or relationship. Obviously.With the contact and connection capacity of the different, the realization of personal expectation opportunity will have obvious difference.
social network is not high, its theoretical foundation is the "six degrees of separation". While the social software is based on the real social network of value-added software and service value no matter how esoteric
theory ", the close combination of six degrees of separation" and the Internet, has begun to reveal the commercial value. The more people pay attention to the study of social network in recent years, more and more network software, also began to support the people to build more trust and tight social association,The software is referred to as the "social software" (Social Software). For example, Blog is a kind of social software, because the Blog needs for writing character and continuity, has enabled the Blogger circle of the Like attracts like. ecological typical form, more and more like a circle in real life. It is dedicated to the study of social software introduction Mao Xianghui, in today's more popular abroad is a kind of fast friends, or business communication tools, such as LinkedIN. People can easily find themselves in the world and the common interests of the people, easier to find business opportunities, to reach the understanding and communication between different ethnic groups, etc..
The definition of social software, and are in constant development and evolution. Its core idea is in fact a polymerization effect. Man, society, business has many kinds of permutation and combination way, if there is no information means together, it is easy to lose. WWW will be successful in text, graphics together, make the Internet become application; instant communication and people together, the ICQ and OICQ tools. However this is virtual, virtual is an advantage of network world, but the requirements and commercial society's real name, separated by a gap of credit. Through acquaintances,Produced by "six degrees of separation" polymerization, will produce a trusted network, the business potential is inestimable.
polymerization as object of social research has practical value. Scientists at the Cornell University have developed an algorithm, to identify an article some of the words "sudden" growth, and these "burst" growth of text can be used to quickly identify the new trend and a hot topic, and thus can be more effective screening of important information. In the past many search technique uses a simple count words / phrases appear frequency method, but ignore the rate increase text using.If this method is applied to advertisers, can quickly find the potential demand of fashion.
social, network, geographical, commercial, Blog, SNS, these words you may have heard numb. However, once those who anticipate people find aggregate their commercial value, change is not only the network world.
20 60's of the 20th century, America psychologist Milgram designed a chain mail experiment. Milgram put the letter sent to live in the city American random part of residents, to write a Boston stockbroker name,And each recipient to send this letter to my view is more close to the stockbrokers friends. The friend received the letter, then the letter sent to his view is closer to the stockbrokers friends. Finally, most of these letters are sent to the hands of stockbrokers, each handling an average of 6.2 letters arrived.
so, milgor lamb raised six degrees of separation theory, think the world between any two individuals to establish contact, only need 6 people
summary
six degrees of separation is a sociological theory, but in fact it is more like a mathematical theory, a lot of people say it and four colour problem have different approaches but equally satisfactory results and wonderful. In my opinion,Six degrees of separation is well described the structure of a mesh of (our human society), enhanced the different links between nodes and connections, however it is not complete, it is not enough to guide our practice. But this theory to a great extent, people have to understand and explore deep in the information era. Analysis and application of relationship strength
the weight problem -- six degrees of separation affirmed the universal relation between man and man, but not for the contact to make quantitative analysis. Our life may know hundreds of people, some of them is extremely important to me, I have to be of little,We contact the reason and method established is also differ in thousands of ways. Parents and relatives the inherent relation, also because the location close to the development of. As the neighborhood relationship, and because the common learning life and development out of the students, the relationship between colleagues. Six degrees of separation theory only put them all down to contact, but not the strong and weak points. In the reticular formation, the relation between people and people, need to be weighted, here, six degrees of separation still incomplete.
in fact, not only the strength and type of relations between the human and the human decisions, but also decided by the degree of six degree theory. It is understandable:The 1 degree relation must be more than 2 degrees between strong. In addition, if in SNS, strength also may according to the established relationship basis to determine, with interest, interest / group / the same circle, with the same application, this kind of relationship is relatively weak, but the more relations with a class intersection relationship may be stronger.
-- the relations and differences between the purpose and results of the
20 60's of the 20th century, Milgram, a social psychologist at the Harvard University (Stanley Milgram) on the design of a chain mail experiment. He will be a chain mail sent to live in the 160 individuals randomly in Omaha, the letter put a Boston stockbroker name,The letter asked each person will this letter to you believe is relatively close to the stockbroker friend. After the friend with that. Finally, most of it after five or six steps all arrived the stock broker.
six degree concept of the resulting segmentation.
this story many six degrees of separation of lovers know, and bible. But I notice the important difference between this story and we are now popular SNS concept. In this story, the letter arrived in Boston stockbroker hand inside yes, but please pay attention to the whole process, each person's friends have not changed. Yes.This is very important, this story's message, and we currently see SNS website hope what are transferred between users? Is the contact or friends?
the linkage experiments, reflects an objective law seems very popular: between the modern human society member, may through the "six degrees of separation" and linked, absolutely no A and B does not exist. This is a more typical, profound and widespread natural phenomenon. So, how to reveal the "six degrees of separation" phenomena in mathematics? This is a significant mathematical conjecture in modern mathematics.
This is a bit like adjacent color map, but adjacent color problem by mathematical method can be used to prove (or at least only use 4 colors can be), and the six degrees of separation theory I can only be estimated by incomplete induction to form hypotheses it, social model or to complex and unpredictable than a two-dimensional map model.
transfer cost -- damping in the Stanley Milgram experiment and torch of the experiment, no cost, or look for the cost of 0. But Is it right? Really cost is 0? Everyone pass the letter took very low, under the name MSN is not cost,However, those who do, is actually looking at a friend's face, so this cost is what? Is Chinese said debt, cost relationship called. No one likes a day to help the help that person, debt and money debt, back must also, this is the transfer of costs.
Gmail invitation until today is still a lot of praise, when just appeared, an invitation can even sell for $60. Many people said it was the greatest marketing. However, until today, many people have become unable to send out the invitation. Why?Because the beginning Gmail is scarce goods, so the high value, plus the Gmail Google with a strong brand and highly user identity, so the more sought after by Gmail, has become a symbol of honor. It is the honor of being invited to the Gmail spread madness in six degrees of separation in the network drive. However, with the high popularity of Gmail, the sense of honor gradually decline, and ultimately reduce the incentive, so that the communication in the doldrums.
damping is good or bad? No damping, we can send messages to any,Each SNS sites are that you only need six person can know Clinton can know Bill Gates, but there are a few people really get to know them? Because they are not worth understanding? No, because the contact looks only six degrees, but each degree of damping are possible are insurmountable. But you do not pessimistic, if there is no damping you might more!
for example. Assume that each person has 30 friends, the information after the six degree calculation, enough to reach a can cover all possible human level. If the connection is six degrees without any damping,To estimate the information of all kinds from friends we received every day will make our heads explode. In our life, an identity more people, more famous people he will have more friends, so he is not want to expand the circle of their relationships, because they tend to be the disturbance. If a moment, damping disappeared, you can easily call Robin Li, Ma Yun, Ma Huateng, you don't want to talk with Feng Xiaogang movie? You can call now. However, we can only say that this was a disaster, many famous people complain, said many people to call their home, saying, "are you XXX?I like you very much. And then hung up the phone. A lot of people extremely scrambling to stop the machine, even for no..
this disaster is a very interesting story for those of us outsiders, once the relationship between flat these celebrities and public (six degree turn after once), their value to the public began to drain, the public can call the past, ask, and then show off oneself to star played telephone, That's it. This huge flat engineering does not extend fans circle of friends, they are still far away from the star......
-- assuming the relationship orientation and transfer problems.SNS website is the most loving words may be "a friend of a friend is a friend", a guy I know if a A friend B is my very repugnant, but my friend there is one C on a B more hate the guy. So in the current SNS service inside me is not a A and a C introduced at the same time, because they were introduced at the same time, it is likely the result of connection was established between a B and a C, began to quarrel.
