Sound
In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.
Technology
Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is first robustly defined by Jacob Bigelow in 1829 as: "...principles, processes, and nomenclatures of the more conspicuous arts, particularly those which involve applications of science, and which may be considered useful, by promoting the benefit of society, together with the emolument [compensation ] of those who pursue them" .
Technology
To appeal to contemporary man to revert, in this twentieth century, to a pagan-like nature worship in order to restrain technology from further encroachment and devastation of the resources of nature, is a piece of atavistic nonsense.
Norman Lamm, Faith and Doubt (1971).
