CELSIUS VERSUS CENTIGRADE

The Ninth General Conference on Weights and Measures, held in October, 1948, adopted the name “Celsius” for the scale of temperature which had more commonly been called “centigrade”. This action, which had not been proposed in advance of the Conference, arose from a question regarding preferred usage in French, the sole official language of the Conference. The decision might be considered as applying strictly only to that language. In the interest of eventual uniformity of practice the use of “Celsius” appeared desirable, but it was not practicable to impose this term on those who preferred “centigrade”.

In preparation for the General Conference the National Bureau оf Standard submitted a revised text defining the International Temperature Scale to supersede that adopted in 1927. The proposed text was drafted in English and, in accordance with common English practice as well as the official French text adopted in 1927, it used the name “centigrade”. This name was earned over into the French translation prepared for consideration by the Advisory Committee on Thermometry in May, 1948. However, in the printed report of that meeting, the term “centigrade” had, in most cases, been changed to “centesimal”, the term that was used in the French law governing weights and measurements. When it was asked to choose between the two, the International Committee on Weights and the General Conference voted to substitute “Celsius”.

With regard to the merits of the decision it might be remarked that Celsius (abbreviated C) was analogous to the names Kelvin, Fahrenheit. Reaumur, and Rankine, used for other temperature scales, that it had previously been used considerably in some countries, and occasionally in America. It might also be argued that “centigrade” was logically ambiguous, since the absolute Kelvin scale, as well as the centigrade scale has 100 degrees between the ice point and the boiling point of water. On the other hand, the name “centigrade” was thoroughly established in English speaking countries, the need for choosing between that name and “centesimal” arose only in French, and the decision on a term in the official French language of the

151

Conference might not be considered as controlling the terms to be used in translating into other tongues.

ANALYTICAL CHEMISTRY – THE OLDEST FIELD

OF CHEMISTRY

Analytical chemistry is probably the oldest field in the broad spectrum of the science of chemistry. Many years were required to dispel the lure of alchemy; more were needed to demonstrate the fallacy of the phlogiston theory. However, it was not until the brilliant French chemist Lavoisier (1743-1794) demonstrated, about 1785, by actual experimental methods that combustion was a combination of a substance with oxygen, that he laid the basic groundwork of modem chemistry, and, in a very particular sense, analytical chemistry. Indeed, with considerable justification he can be called the “father” of analytical chemistry because of the great emphasis he placed in all experimental work on quantitative measurement. It is in this very necessary characteristic of the true analytical chemist that he differed

152

from Priestley(1733-1804), a discoverer of oxygen. Priestley, a clergyman forced to flee from Birmingham, England, to America because of his unorthodox political and religious views, was more of a philosopher than a scientist.

The first problem to engage the interest of most chemists was to determine as exactly as possible the composition of the earth. Greater emphasis was perhaps placed on chemistry than physics at this stage in the evolution of the natural sciences - yet, the contributions of such scientists as Avogadro, Boyle, and Charles all had a direct bearing and, therefore, great usefulness in analysis. Avogadro’s law, for example, is extremely important in the chemistry of gases, because it docs serve as a basis for relating weight to volume. Indeed, it is not an overstatement to say that during the 18th and most of the 19th century the chemistry that did exist was largely analytical chemistry. The pinnacle of ambition of most chemists at that time was to be a highly successful analyst. Any study of chemical literature of this period shows a preponderance of titles related to analytical chemistry.

It was in the latter half of the 19th century that the so-callcd “industrial revolution’’ took place. Many beginnings (modest at first) were made in the industrial manufacture of numerous items consumed in the household which were traditionally produced in the home or not at all. The raw materials in such manufacturing operations consisted chiefly of chemicals.

The pressing and dyeing of textiles, the production of glass, leather, soap - these are merely four examples (many others could be quoted) of operations that moved slowly out of the home and into the factory. Slowly, but surely, this trend built up a demand for modest changes for a limited number of chemicals. Except for the natural dyes and tanning extracts, most of the industrial chemicals produced in this area were inorganic in nature, principally alkalies, mineral acids, etc.

ENVIRONMENT PROTECTION MUST BE GLOBAL

That the problem of pollution and ecology has become the most important one for mankind is evident to all. The more civilization is developing, 1…………. .Air and water pollution by industry is now reaching tremendous proportions. In our era it is changing from a national to international problem, 2………………. . The seas and oceans are also becoming seriously polluted. A similar situation is

154

developing in the atmosphere. It is known that many cities throughout the world suffer from air pollution.

However, our scientific knowledge and technological advancement make it possible to eliminate it 3………………… . The development of natural resources on a global scale is already possible from a scientific and technical standpoint (точка зрения). Large-scale experimental work in this area is successfully being carried out.

At present scientists in industrially developed countries are working on the theory of interaction of all the atmospheric and oceanic global processes that determine the climate and weather of the world. Increasing growth of population, industrialization and the use of resources 4……………. .This can be described as a great experiment, one that may bring about changes in the environment more serious than ever before.

The essential feature in the environment protection is that many problems can be solved only on the level of world community.

Therefore, the planning of protection against pollution by human society as a whole is 5……………….. . It is necessary to develop an international program to study data on land, forest, atmospheric and oceanic resources, both renewable and non-renewable. It is the joint efforts of many scientists and special public organizations that can deal with the problem and take 6………………. .

It is still a big job and much remains to be done (еще многое предстоит сделать). However, scientists are confident that planned actions of all countries can eliminate pollution and achieve successes in purifying air, water and soil and in safeguarding natural resources. At the same time one must realize that social and political circumstances may stand in the way of further progress in this
