In classifications, scientist refers to a student of the knowledge of the material world and the energy world.

Etymology
The term "scientist" as a student of the knowledge of the material world was coined by English mathematical philosopher William Whewell in 1833 in the context of and followup to the Whewell-Coleridge debate. Whewell introduced the term to replace the older term ‘natural philosopher’, a subtle caveat, however, being that the ‘material world’, in unwritten assumption, should not be confused with the ‘moral world’, which is the work of a deity.
