Every profession or trade, every art, and every science has its technical vocabulary, the function of which is partly to designate things or processes which have no names in ordinary English, and partly to secure greater exactness in nomenclature. Such special dialects, or jargons, are necessary in technical discussion of any kind. Being universally understood by the devotees of the particular science or art, they have the precision of a mathematical formula. Besides, they save time, for it is much more economical to name a process than to describe it. Thousands of these technical terms are very properly included in every large dictionary, yet, as a whole, they are rather on the outskirts of the English language than actually within its borders.
Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other vocations, like farming and fishery, which have occupied great numbers of men from re mote times, the technical vocabulary, is very old. It consists largely of native words, or of borrowed words that have worked themselves into the very fiber of our language. Hence, though highly technical in many particulars, these vocabularies are more familiar in sound, and more generally understood, than most other technicalities. The special dialects of law, medicine, divinity, and philosophy have also, in their older strata, become pretty familiar to cultivated persons, and have contributed much to the popular vocabulary. Yet every vocation possesses a large body of technical terms that remain essentially foreign, even to educated speech. And the pro portion has been much increased in the last fifty years, particularly in the various departments of natural and political science and in the mechanic arts. Here new terms are coined with the great freedom, and abandoned with indifference when they have served their turn. Most of the new coinages are confined to special discussions, and seldom get into general literature or conversation. Yet no profession is nowadays, as all professions once were, a close guild. The lawyer, the physician, the man of science, the divine, associates freely with his fellow-creatures, and does not meet them in a merely professional way. Furthermore, what is called "popular science" makes everybody acquainted with modem views and recent discoveries. Any important experiment, though made in a remote or provincial laboratory, is at once reported in the newspapers, and everybody is soon talking about it--as in the case of the Roentgen rays and wireless telegraphy. Thus our common speech is al ways taking up new technical terms and making them commonplace. (419)

问答题When the leaders of media, telecommunications, IT and Internet companies congregate, as they did recently in Davos, the talk is upbeat about new accomplishments but subdued about recent ordeals: the dotcom bubble; the telecoms crash; the music industry bust; the advertising downturn; the e-publishing revenue stagnation; the PC slowdown; the wireless saturation; the semiconductor slump; the newspaper recession; tile R&D retrenchment. And the question is, why do these predicaments sweep over the information sector so regularly The prevalence of these problems points to fundamental issues beyond a specific industry or short- term period. Instead, we need to recognize that the entire information sector — from music to newspapers to telecoms to Internet to semiconductors and anything in-between — has become subject to a gigantic market failure in slow motion. A market failure exists when market prices cannot reach a self-sustaining equilibrium. The market failure of the entire information sector is one of the fundamental trends of our time, with far-reaching long-term effects, and it is happening right in front of our eyes. The basic structural reason for this problem is that information products are characterized by high fixed costs and low marginal costs. They are expensive to produce but cheap to reproduce and distribute, and therefore exhibit strong economies of scale with incentives to an over-supply. Second, more information products are continuously being offered to users. And information products and services are becoming more commodified , open, and competitive.
