Question

　　Usually social scientists have greater difficulty in their research work than physical scientists. By that I do not mean to belittle (cause to seem unimportant) the great achievements of physical scientists, who have been able, for example, to describe the atom(原子) without seeing it. That is a splendid achievement, yet in many ways it is not so difficult as what social scientists are expected to do. The conditions under which social scientists must work would drive a physical scientist mad. Here are five of those obstacles (障碍) . He can make few experiments, he cannot measure the results exactly, he cannot control the conditions surrounding the experiments, he is often expected to get quick results with low-acting economic force, and he must work with people, not with objects.
