Famous quotes containing the words radio, medium and/or wave:
“The radio ... goes on early in the morning and is listened to at all hours of the day, until nine, ten and often eleven o’clock in the evening. This is certainly a sign that the grown-ups have infinite patience, but it also means that the power of absorption of their brains is pretty limited, with exceptions, of course—I don’t want to hurt anyone’s feelings. One or two news bulletins would be ample per day! But the old geese, well—I’ve said my piece!”
—Anne Frank (1929–1945)
“In the one instance, the dreamer ... loses sight of this object in a wilderness of deductions and suggestions ... until ... he finds the incitamentum, or first cause of his musings,... forgotten. In my case, the primary object was invariably frivolous, although assuming, through the medium of my distempered vision, a refracted and unreal importance.”
—Edgar Allan Poe (1809–1849)
“The wave of evil washes all our institutions alike.”
—Ralph Waldo Emerson (1803–1882)
