Navigation
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.
Radio
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I really worked, is mine.

It is impossible to understand the American public without taking into account the tremendous psychological effect of bringing up a generation of people in a daily environment of advertising. It is impossible to escape the advertising man; his sales talk assaults us in the morning newspaper, in the street car, with billboards along the highways, and in his shameless use of the radio. This means that from morning till night, in the midst of our work as in our recreation, we live constantly in an atmosphere of intellectual shoddiness. Every popular prejudice and vulgar conceit is played upon and pandered to in the interests of salesmanship. Everywhere material interests and herd opinion are strengthened to the loss of personal independence. The tendency is to think and speak for effect rather than out of one's inner life. There is a marked decline the ability to play with ideas, or to live the spiritual life for its own sake. Hence a decline in civilization of interest, humor and urbanity. Advertising tends to make mechanized barbarians of us all.
