In the late 19th century, a man named Sir Francis Galton made the first attempt to scientifically measure human intelligence. Galton tried to use a psychological approach to his testing, rather than the medical /anatomical approach of scientists and researchers before him. From 1884 to 1890, Galton ran a service in a museum in London, where people could pay for a test of their intelligence. However, the specific tests that Galton chose to use were not very good ones. For example, in one test, Galton tried to find the highest-pitched sound a person could perceive, so he made a whistle for people to listen to. In another test, he tried to measure people’s sensitivity to the smell of roses. Thus, Galton tried to show that intelligence could have a scientific measure, but he was not able to create a test that truly did this.
The average population density of the world is 47 persons per square mile. Continental densities range from no permanent inhabitants in Antarctica to 211 per square mile in Europe. In the western hemisphere, population densities range from about 4 per square mile in Canada to 675 per square mile in Puerto Rico. In Europe the range is from 4 per square mile in Iceland to 831 per square mile in the Netherlands. Within countries there are wide variations of population densities. For example, in Egypt, the average is 55 persons per square mile, but 1,300 persons inhabit each square mile in settled portions where the land is arable.
The interpretation of words is a never-ending task for any citizen in a modern society. As a result of modern means of communication, we now have hundreds of thousands of words flung at us daily. We are constantly being talked at, by teachers, preachers, salesmen, and public officials. In some houses, the radio is never turned off from morning to night. In large cities, the newsboy brings us the daily newspaper, from thirty to fifty enormous pages of print, and almost three times that amount on Sunday. The mailman brings magazine and direct-mail advertising. We go out and get more words at bookstores and libraries, and billboards confront us on highways. Words fill our lives.
