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 Nobel Prize, a widely regarded prestigious award, is awarded annually to those who have achieved scientific advances in the fields of medicine, physics, and chemistry. 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. Research interests Scientists include experimentalists who mainly perform experiments to test hypotheses, and theoreticians who mainly develop models to explain existing data and predict new results. There is a continuum between two activities and the division between them is not clear-cut, with many scientists performing both tasks. Those considering science as a career often look to the frontiers. These include cosmology and biology, especially molecular biology and the human genome project. Other areas of active research include the exploration of matter at the scale of elementary particles as described by high-energy physics, and materials science, which seeks to discover and design new materials. Others choose to study brain function and neurotransmitters, which is considered by many to be the "final frontier". There are many important discoveries to make regarding the nature of the mind and human thought as much still remains unknown.

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. United States According to the National Science Foundation, 4.7 million people with science degrees worked in the United States in 2015, across all disciplines and employment sectors. The figure included twice as many men as
