binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use latin grammatical forms, although they can be based on words from other languages. such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also called a latin name. the first part of the name – the "generic name" – identifies the genus to which the species belongs, while the second part – the specific name or specific epithet – identifies the species within the genus. for example, humans belong to the genus "homo" and within this genus to the species "homo sapiens". "tyrannosaurus rex" is probably the most widely known binomial. the "formal" introduction of this system of naming species is credited to carl linnaeus, effectively beginning with his work "species plantarum" in 1753. but gaspard bauhin, in as early as 1622, had introduced in his book "pinax theatri botanici" (english, "illustrated exposition of plants") many names of genera that were later adopted by linnaeus.

there are different types of biologists. theoretical biologists use mathematical methods and develop models to understand phenomena and ideally predict future experimental results, while experimental biologists conceive experiments to test those predictions. some biologists work on microorganisms, while others study multicellular organisms (including humans). some investigate the nano or micro-scale, others emergent properties such as ecological interactions or cognition. there is much overlap between different fields of biology (e.g. zoology, microbiology, genetics and evolutionary biology) and due to the interdisciplinary nature of the field it is often difficult to classify a life scientist as only one of them. many biological scientists work in research and development. some conduct fundamental research to advance human knowledge of life. furthermore, applied biological research often aids the development of solutions to problems in areas such as human health and the natural environment. biological scientists mostly work in government, university, and private industry laboratories.
