query: What is the field of study to become a scientist?
passage: Scientist
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. Although there have been remarkable discoveries with regard to brain function and neurotransmitters, the nature of the mind and human thought still remains unknown.
passage: Candidate of Sciences
Kandidat nauk (, literally ""Candidate of Sciences"") is the first of two doctoral level scientific degrees in some former Soviet countries. It is formally classified as UNESCO ISCED level 8, 'doctoral or equivalent', and is thus officially translated into English and other languages as Doctor of Philosophy (i.e. PhD) and recognised as such.
