Why do some people a chance to be more fat than others to consider this issue. Common sense tells us that some people eat too much, so heavier. But why is it so? • Nicholas Christakis (Nicholas Christakis) in the Framingham Heart Study (Framingham Heart Study) • James Fowler (James Fowler) use social network approach to study the problem. More than 12,000 people from their network of people drawn in the study: People gain weight and their spouses, friends, siblings and neighbors have a relationship to gain weight; this relationship even beyond the scope of direct social relationships, and even never met a stranger people also can affect your fat or thin.
Finally, discuss the idea spread on social networks. We rely on common sense judgment is that when you intend to develop new products or try to convince others of the time, the closest relationship will most influential people. But the study of the relationship between the network of those who have found a relationship with your general outside your immediate circle instead of the most right to speak.
Affect our social networks on our lives is important. For example, when a group of people, only a close friend, family, co-workers and a coterie circle of no other words, this small group can sometimes be harmful breeding hotbed of ideas and practices. For example, in the cultural and geographical differences in the huge North American cities and towns on the island in Micronesia and the Western Pacific on the same place in each youth “contagion” of suicides.
This idea is not only to change in the social sciences. Social networks also have a great impact on biology and physics. Take the basic unit of the gene we are most familiar organisms, we all know that genes determine our features: from hair color to like to put a rubber band tied to the wrist by genes determine hobby. Now, evolutionary biologists began to complex social network relationships at different levels of modeling: from the genome of each base, the interaction network of proteins and genes to the interactive network between organisms. These studies show that our genes has been able to dominate our destiny lies in the interaction between them and their interaction with the outside world.
