It involves the study of algorithms that process, store, and communicate digital information. A computer scientist specializes in the theory of computation and the design of computational systems.
Science is a strict systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the world. [1] [2] Modern science is typically divided into three major branches: [3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study ...

While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them. Many of those names are known only to professionals.
Scientific evidence. Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, [ 1] although scientists also use evidence in other ways, such as when applying theories to practical problems. [ 2] Such evidence is expected to be empirical evidence and interpretable in accordance with the ...
Simple Knowledge Organization System ( SKOS) is a W3C recommendation designed for representation of thesauri, classification schemes, taxonomies, subject-heading systems, or any other type of structured controlled vocabulary.
