Definitions and quotes

Microwave
Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm). Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio engineering is the range between 1 and 100 GHz (wavelengths between 300 and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.
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.

Books are the friends of solitude. They develop individuality and freedom. In solitary reading a man who is seeking himself has some chance of finding himself. … Radio, on the other hand, is now the chief agent of imperialism. It does not purify the spirit of man, does not, like the book, bring him back to the sanctuary of solitude, but throws him to the lions, subtly preparing his mind for the blood and chains of public sacrifice.
Georges Duhamel, In Defense of Letters (1937), E. Bozman, trans. (1939), p. 42
Radio
First radio, then television, have assaulted and overturned the privacy of the home, the real American privacy, which permitted the development of a higher and more independent life within democratic society.
Allan Bloom, The Closing of the American Mind (New York: 1988), p. 58
Radio
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.

An EU team modelled factors affecting the life cycle of mobile phones. Utilising Israeli householder data, the study examined the linked economic and environmental effects of four types of industry-player companies.
