c.1300, "knowledge (of something) acquired by study," also "a particular branch of knowledge," from O.Fr.
science, from L.
scientia "knowledge," from
sciens (gen.
scientis), prp. of
scire "to know," probably originally "to separate one thing from another, to distinguish," related to
scindere "to cut, divide," from PIE base
*skei- (cf. Gk.
skhizein "to split, rend, cleave," Goth.
skaidan, O.E.
sceadan "to divide, separate;" see
shed (v.)). Modern sense of "non-arts studies" is attested from 1678. The distinction is commonly understood as between theoretical truth (Gk.
episteme) and methods for effecting practical results (
tekhne), but
science sometimes is used for practical applications and
art for applications of skill. Main modern (restricted) sense of "body of regular or methodical observations or propositions ... concerning any subject or speculation" is attested from 1725; in 17c.-18c. this concept commonly was called
philosophy. To
blind (someone) with science "confuse by the use of big words or complex explanations" is attested from 1937, originally noted as a phrase from Australia and New Zealand.
