"The microphone-amplifier-loudspeaker combination is having an enormous effect on our civilization. Not all of it is good! Consider to what heights of impudence and tyranny, and to what depths of moral depravity, has radio broadcasting and the loudspeaker attained in that recent monstrosity, Transit Radio, Inc. Almost incredible is the loathsome fact that already in 21 cities bus riders must listen to never-ending, blatant advertising and unwelcome jitterbug and bop music."

“Unwittingly then had I discovered an Invisible Empire of the Air, intangible, yet solid as granite, whose structure shall persist while man inhabits the planet.”

“I foresee great refinements in the field of short-pulse microwave signaling, whereby several simultaneous programs may occupy the same channel, in sequence, with incredibly swift electronic communication; vastly important developments in microwave technique, whereby present clumsy connecting leads between wall or floor sockets and electric devices like toasters and vacuum sweepers may become unnecessary; gigantic magnetrons and klystrons, or their successors, will generate megawatts in microwaves; living rooms and their occupants will be heated by high-frequency waves from walls or ceilings; short waves will be generally used in the kitchen for roasting and baking, almost instantaneously”

“To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth—all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances.”

“The actual poetry of this engineering triumph was first brought stunningly upon me in 1915 when I sat in an audience in San Francisco and heard the breaking of the surf upon the far Atlantic shore.”

“The children of the white families in town were not permitted to associate with me, because my father was committing the then unpardonable crime, in Southern eyes, of educating negroes.”

“So I repeat that while theoretically and technically television may be feasible, yet commercially and financially, I consider it an impossibility; a development of which we need not waste little time in dreaming.”
