History

The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natural historians, natural theologians, engineers, and others who contributed to the development of science) have had widely different places in society, and the social norms,

Whewell wrote of "an increasing proclivity of separation and dismemberment" in the sciences; while highly specific terms proliferated—chemist, mathematician, naturalist—the broad term "philosopher" was no longer satisfactory to group together those who pursued science, without the caveats of "natural" or "experimental" philosopher. Whewell compared these increasing divisions with Somerville's aim of " enderinga most important service to science" "by showing how detached branches have, in the history of science, united by the discovery of general principles." Whewell reported in his review that members of the

Career

After the completion of their training, many scientists pursue careers in a variety of work settings and conditions. In 2017, the British

'' published the results of a large-scale survey of more than 5,700 doctoral students worldwide, asking them which sectors of the economy they would like to work in. A little over half of the respondents wanted to pursue a career in academia, with smaller proportions hoping to work in industry, government, and nonprofit environments. Other motivations are recognition by their peers and prestige. The

. Some scientists have a desire to apply scientific knowledge for the benefit of people's health, the nations, the world, nature, or industries (academic scientist and industrial scientist). Scientists tend to be less motivated by direct financial reward for their work than other careers. As a result, scientific researchers often accept lower average salaries when compared with many other professions which require a similar amount of training and qualification.

Demography

By country

The number of scientists is vastly different from country to country. For instance, there are only four full-time scientists per 10,000 workers in India, while this number is 79 for the United Kingdom, and 85 for the United States.

in 2015, across all disciplines and employment sectors. The figure included twice as many men as women. Of that total, 17% worked in academia, that is, at universities and undergraduate institutions, and men held 53% of those positions. 5% of scientists worked for the federal government, and about 3.5% were self-employed. Of the latter two groups, two-thirds were men. 59% of scientists in the United States were employed in industry or business, and another 6% worked in non-profit positions.

By gender

Scientist and engineering statistics are usually intertwined, but they indicate that women enter the field far less than men, though this gap is narrowing. The number of science and engineering doctorates awarded to women rose from a mere 7 percent in 1970 to 34 percent in 1985 and in engineering alone the numbers of bachelor's degrees awarded to women rose from only 385 in 1975 to more than 11000 in 1985.
