Actually, what occurred to Einstein was something more like the beginning of a solution to
panic
A panic is a form. of collective in which a group of people, face with an immediate threat, re- act in an uncoordinated and irrational way. Their behawor is uncoordinated in the sense that co- operative social relationships and break down. It is irrational in the sense that people&39;s actions are not appropriate for the goals they wish to achieve.
The progress of a panic follows a fairly typical course. A sudden crisis occurs ; people experi- ence intense fear; normal social expectations are broken; each individual tries desperately to es- cape from the source of danger; mutual cooperation breaks down; and the situation becomes even more threatening as a result. Panics are especially likely to occur in unusual conditions in which everyday norms have little relevance, such as fires, floods, earthquakes or military invasions.
Some kind of response is necessary in these situations, but there are few social norms that specify an appropriate reaction. Thus, when a passenger aircraft makes a crash landing people may at- tempt to flee before fire breaks out and cause an explosion, but there only succeed in stopping themselves and others by creating bottlenecks at the exits. Awareness of bottlenecks, may lead to increased panic, with people fighting and trampling one another in the effort to escape. Despite intensive training of airline personnel in emergency evacuation procedures, a high proportion of passenger deaths are caused by a panic that prevents people from escaping in time.
The most dramatic panics are those that occur in situations of extreme emergency, but not all panics are quite so frantic or short-lived. A different form. of this collective behavior. is the finan- cial panic, which is typically provoked by rumor that the price of stocks will fall or that a bank will be unable to repay its depositors. The classic example, of course, occurred at the outset of the Great Depression in 1929: as in other forms of panic, the individuals involved tried to protect their own interests, and in so doing they worsened the situation for themselves and everyone else. By trying to sell their stocks as quickly as possible, people ensured that the price of stocks did fall; by demanding their money back from banks, they ensured that the banks actually did collapse.

Understanding anthropology requires understanding its dual nature. Perhaps two inelegant but useful terms borrowed from linguistics will help. Emic refers to the array of categories (and their systematic relationships) through which the bearers of a particular culture perceive the world. Eric refers to the array of categories (and their systematic relationships) used by Western social scientists to explain the word. In other words, the emic view is the insider's, the participant's view, and the etic is the outsider's, the scientific observer's view. Pierre's emic view of his death, for exam- pie, is that he died from the power of the sorcerer; the anthropologist's "etic view" is that he died from physiological effects of fear, induced by his belief in the sorcerer. Both views are valid under the proper circumstances, but anthropology requires that they be clearly distinguished from each other because they derive from different methodologies, consist of different kinds of data, and lead to different types of knowledge. Together they facilitate a complete understanding of a culture. Anthroplogy's uniqueness lies in the fact that it encompasses them both.
In this passage the author mainly attempts to ______.
A.explain what anthropology is concerned with
B.compare two different schools of anthropology
C.show people how anthropologists do their studies
D.distinguish anthropology from other disciplines
In what kind of sleep does dreaming occur?
Dreaming occurs in ______.
Although April did not bring the rains we all hoped for, and although the Central Valley doesn’t generally experience the atmospheric (大气的) sound and lightning that can accompany those rains, it is still important for parents to be able to answer the youthful questions about thunder and lightning.
The reason that these that these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lighting we see flashing(闪烁) down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes cheat us into thinking we see a downward motion when it’s actually the other way round. But then, if we believe only what we think we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between the earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on the earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashes reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval between the flash and the crash to learn how close they are to the actual spark.

C. People can seldom see lightning flashes running between two clouds or between the earth and a cloud.
